Easy Oven-Dried Tomatoes for Paleo Snacks

Ok so my recipe isn’t strictly accurate, as my tomatoes are oven-dried tomatoes rather than sun-dried – and my method doesn’t take 7-days, but the end result is the close enough. These are such a simple alternative to buying sun-dried tomatoes, and come with no preservatives or added nasties.

Use different colours and varieties of tomatoes and put these in a jar, to make a beautiful and practical gift.

Instead of basil, you can experiment with your favourite combinations. Try some other Italian herbs, garlic or even lemon for some variety. Capsicum (bell pepper) is also great dried out using this method and complements the sun-dried tomatoes perfectly.

Equipment

  • Baking Tray
  • Grease-proof paper
  • Bowl

Ingredients

  • 250 g tomatoes I used regular cherry tomatoes, but have got some colourful varieties growing in my garden to try next time
  • Splash of extra virgin olive oil
  • 1 teaspoon of dried basil
  • Sea salt and black pepper to taste

Instructions

  • Preheat the Oven: First, preheat your oven to 150°C (300°F).
  • Prepare the Tomatoes: Slice the tomatoes in half, lengthways. It helps to keep them all evenly sized.
  • Mix the Ingredients: In a bowl, mix all the ingredients, ensuring the tomato halves are evenly coated with olive oil, dried basil, sea salt, and black pepper.
  • Arrange on Baking Tray: Line a baking tray with grease-proof paper, and arrange the tomatoes evenly on the tray. It’s fine if some face up and some down.
  • Bake: Bake for 2 – 3 hours, ensuring they don’t burn. You’ll want the tomatoes to retain a little moisture to ensure a nice texture.
  • Store: Store your oven-dried tomatoes in an airtight container in the fridge.

Alternative Method: Alternatively, you can simply dry out the tomatoes in a dehydrator, if you have one.

Tips for Choosing the Best Tomatoes

For the richest flavour, opt for small, firm tomatoes like Roma, cherry, or grape varieties. These types naturally have a lower water content, which helps them dry more efficiently and intensify in taste. You can also use heirloom varieties to add visual appeal to your final product, especially if you're giving them as a gift. Always choose ripe, unblemished tomatoes for the best results.

Storage and Shelf Life

Once fully dried, your oven-dried tomatoes should be stored in an airtight container or jar. You can store them dry, or pack them in olive oil with herbs for a ready-to-use ingredient. In the fridge, they’ll last around a week if packed in oil, or longer if vacuum sealed or kept in the freezer. Just ensure they're completely cool before sealing to avoid excess moisture.

Pairings and Serving Suggestions

These tomatoes add bursts of flavour to almost any dish. Add them to a Paleo-style antipasto platter with cured meats, olives, and fermented veggies. Chop and mix into your favourite guacamole or toss through a fresh zucchini noodle salad with basil and almonds. They’re also incredible on Paleo wraps or flatbreads with grilled chicken or lamb.

Batch Prep and Scaling Up

Because drying tomatoes takes time, consider making a large batch at once. Use multiple trays if your oven allows. Rotate them halfway through the drying time to ensure even dehydration. When using a dehydrator, you can run several trays simultaneously, making it more energy-efficient if you plan to preserve lots of produce from your garden or a market haul.

Creative Gifting Ideas

Layer a selection of oven-dried tomatoes, roasted capsicum, and fresh herbs like thyme or rosemary in a glass jar and top with good-quality olive oil. Tie with string and a handwritten label for a beautiful homemade gift. For an added touch, include a tag with recipe suggestions or a pairing guide. It’s the kind of present that feels thoughtful, delicious, and practical all at once.

Why They’re Better Than Store-Bought

Many commercial sun-dried tomatoes contain preservatives like sulphites, which can cause adverse reactions in sensitive individuals. By making your own, you control every ingredient—there’s no sugar, additives, or processed oils. Plus, they’re far more cost-effective than their store-bought counterparts.

Fun Variations to Try

  • Spicy Kick: Add a pinch of chili flakes or cayenne before drying.
  • Smoky Flavour: Try smoked paprika for a deeper, earthy undertone.
  • Middle Eastern Twist: Add ground cumin and coriander with fresh mint after drying.
  • Herb Infused Oil: After storing in oil, toss in a few sprigs of thyme or oregano to deepen the flavour over time.

Using Oven-Dried Tomatoes in Everyday Meals

Once you've mastered making oven-dried tomatoes, the real fun begins with incorporating them into your regular meals. Their deep, sweet-savory flavour can completely transform simple dishes. Toss them through scrambled eggs or a veggie-loaded frittata for an instant flavour boost. Add a handful to a tray of roasted vegetables just before serving, or stir into cauliflower rice for a Mediterranean flair. They also work beautifully in slow-cooked dishes, where their richness intensifies further and adds depth without overpowering other ingredients.

Paleo-Friendly Sauces and Dressings

Blending your oven-dried tomatoes into sauces and dressings is another excellent way to use them. For a simple Paleo pasta sauce, blend a handful of dried tomatoes with olive oil, garlic, fresh basil, and a touch of lemon juice. You can thin it with water or bone broth for a looser consistency. This works perfectly over spiralised zucchini noodles or grilled vegetables. For a salad dressing, pulse them into a vinaigrette with apple cider vinegar and Dijon mustard. The result is a bold, tangy dressing that livens up any salad without the need for additives or emulsifiers.

Turn Them Into a Savoury Spread

Another creative idea is to use your dried tomatoes as the base for a spread or dip. Blend with soaked cashews, garlic, lemon juice, and herbs to create a creamy tomato spread that’s perfect for Paleo crackers or raw veggie sticks. For a nut-free option, blend them with roasted red capsicum and a splash of olive oil for a simple tapenade-like dip. It makes an excellent addition to grazing boards or packed lunches and is a great way to add interest to leftovers.

Protein Pairings for Maximum Flavour

Oven-dried tomatoes pair wonderfully with many protein sources, especially within a Paleo framework. Toss them through a lamb salad with mint and cucumber, or use them to top grilled chicken thighs with fresh herbs and avocado. They’re also brilliant in slow-cooked beef dishes, bringing natural acidity and richness. If you eat eggs, they’re an easy upgrade to any omelette or egg muffin. With seafood, try them in a warm salad with prawns, olives, and rocket for a nutrient-dense lunch.

Make a Paleo-Friendly Tapenade

If you're missing traditional tapenade, these tomatoes can help. Blend them with olives, garlic, and a drizzle of olive oil for a robust, savoury spread that works on everything from Paleo bread to lettuce wraps. You can keep it chunky or blend until smooth depending on your preference. Add a few toasted pine nuts for texture or a splash of lemon juice to brighten the flavour. Store in a jar in the fridge and use within a few days.

Meal Prep with a Mediterranean Twist

Including oven-dried tomatoes in your weekly meal prep can bring variety to your usual rotation. Add them to pre-cooked chicken and steamed greens for easy lunches, or mix with roasted sweet potatoes, rocket, and tahini dressing for a plant-based bowl. Their concentrated flavour means you only need a few pieces to change the entire dish, so they’re ideal for portion-controlled meals or adding variety without extra prep each day.

Use in Paleo Baking

Believe it or not, oven-dried tomatoes also have a place in savoury baking. Add finely chopped tomatoes to almond flour muffins, seed crackers, or savoury scones for bursts of flavour. They pair particularly well with rosemary, thyme, and black olives in rustic-style breads or focaccia-style bases. Just ensure they’re well-dried and chopped small to avoid adding too much moisture to your mix.

Incorporating Them Into Entertaining Platters

When entertaining, having a jar of your homemade oven-dried tomatoes on hand can elevate your offerings. Serve them with crudités, compliant cured meats, activated nuts, and fermented vegetables for a well-rounded Paleo platter. Their bold taste balances beautifully with creamy elements like avocado or goat cheese (if tolerated), making them a reliable go-to for creating vibrant, nutrient-dense spreads.

Building a Seasonal Pantry

If you grow your own tomatoes or shop seasonally, oven-drying is the perfect preservation method. When tomatoes are abundant and inexpensive, make large batches and store them in portions. You’ll capture that peak flavour to use all year long, even when supermarket tomatoes are bland and watery. Stored properly, they retain their taste and texture, making them a pantry essential through winter months.

Creating a Flavour Base for Paleo Dishes

Think of these tomatoes as flavour bombs you can drop into a range of dishes. Chop and sauté them with onions and garlic as a base for soups and stews. Stir into bone broth for a quick lunch soup, or mash into ghee and melt over steak or grilled fish. Their natural umami quality enhances the depth of meals without needing artificial flavour enhancers or sauces.

Beyond Tomatoes: Experiment With Other Veggies

Once you’re comfortable with the method, try it with other produce. Capsicum is a natural pairing, but zucchini, mushrooms, and even thinly sliced carrots can all be oven-dried with great results. Follow the same slow-drying principle and experiment with spice combinations. Mixing different dried vegetables in a jar with herbs and oil makes a colourful, deeply flavoured base for countless meals.

A Delicious Habit Worth Keeping

Making your own oven-dried tomatoes might feel like a novelty at first, but it’s the kind of low-effort, high-reward habit that becomes second nature. With minimal ingredients and a bit of patience, you’ll have a versatile, flavour-packed staple that’s free from additives and perfectly suited to the Paleo lifestyle. Plus, they make your meals look and taste gourmet, even when you’re just throwing something together from the fridge. So next time tomatoes are in season, buy extra — your future self will thank you.

Final Thoughts

Oven-dried tomatoes are a deceptively simple recipe that delivers big on both flavour and versatility. They’re one of those make-ahead pantry staples you’ll reach for constantly, whether to elevate a meal or enjoy as a nourishing snack. Play around with herbs and oils to suit your taste or seasonal availability, and don’t forget to tag your creations on social if you share them—I’d love to see how you make them your own!

How to Stop Herbs and Spices Clumping Together

It can't just be me – I come to use a particular jar of dried herb, spice or seasoning, to find it completely stuck together and impossible to get out. It's so frustrating, and seems to be worse with onion and garlic powder, which always seem to cake soon after the containers are opened.

This happens when moisture and humidity get into the container causing it to clump together and form a rock. Whilst the moisture will reduce the flavour and strength of the herbs, a lot of them you can re-invigorate by removing the moisture. Far less wasteful than throwing unused herbs and spices away.

Herbs Spices Seasoning Moisture Storing Clumping Caking the Paleo Network-min

How to remove the moisture

The easiest way is in the oven. I heat my oven to about 125C (250F) and use a metal skewer to get break the clump (or in this case garlic powder) out of the container, onto a sheet of baking paper, on a baking tray.

After just a couple of minutes, the heat will have removed the moisture, and I remove the tray and allow it to cool. Once cooled, I transfer it back into the container using a funnel and it now dispenses freely!

To prevent it happening again

Make sure the containers you store your dried herbs,spices and seasonings in are completely air-tight and always shut the lid/ close the container properly. Storing somewhere cool and dark (or even in the freezer!) will also help prevent moisture coming into contact with the inside of the container.

Avoid the temptation to shake the container directly into a pot of steaming food – this will allow moisture in. Spoon what you need out of the container, away from the stove top.

You can also add some dried beans or rice to the container to absorb any moisture and prevent the mixture from clumping.

Storing the containers upside down will also help prevent air getting in, making them last longer.

Why Some Spices Are More Prone to Clumping

Not all herbs and spices react the same way when exposed to moisture. Fine powders like onion powder, garlic powder, cinnamon, and ground ginger tend to absorb moisture far more quickly than coarser blends. This is because the finer the grind, the greater the surface area exposed to the air. Seasonings that contain natural sugars, like onion and garlic powder, are even more susceptible as sugar attracts and holds onto moisture. Blends with added salt can also clump faster, especially if the salt used is unrefined and retains trace minerals.

The Impact of Humidity in Australian Kitchens

Here in Australia, particularly in coastal or tropical regions, humidity plays a major role in spice spoilage. Even when your kitchen feels dry, the ambient moisture in the air can still creep into containers if they’re not properly sealed. During summer, when humidity levels peak and windows are more likely to be open, your spice rack can become a hotspot for clumping. Using a dehumidifier in your pantry or switching to moisture-resistant storage solutions can make a big difference in maintaining spice quality year-round.

How Long Do Herbs and Spices Actually Last?

While dried herbs and spices don’t necessarily “go off” like fresh produce, they do lose potency over time. Most ground spices stay fresh for around 6 months to a year, while whole spices can last up to 2 or 3 years when stored correctly. The issue with clumping is that it often signals early degradation caused by moisture, which speeds up flavour loss. If a spice no longer smells fragrant or tastes sharp, it’s probably time to replace it — regardless of its expiry date.

Reviving Clumped Spices Without Heat

If you don’t want to use your oven, there are a few gentler ways to rescue stuck-together spices:

  • Use a blender or spice grinder: Transfer the clumped spice to a grinder or mini blender and pulse it back into a fine powder. Make sure the appliance is completely dry before use.
  • Microwave method: Place the spice on a paper towel and microwave it in 10-second bursts. Stir between each burst and stop once the mixture is dry and loose again.
  • Silica gel packs: Place a food-safe silica packet in your spice container to draw out moisture without the need for heat.

Choose the Right Storage Containers

The type of container you use has a huge impact on spice longevity. Glass jars with rubber-sealed lids are ideal, as they create a tight barrier against air and humidity. Avoid plastic containers with ill-fitting lids, as they allow moisture to seep in slowly over time. Dark or amber glass jars can also protect the spices from light exposure, which breaks down essential oils and dulls the flavour. If you're decanting bulk spices, label them with the purchase date so you can keep track of their age.

Best Practices for Refilling Spice Jars

When refilling your spice containers, avoid topping up old spices with new ones. It’s better to wash and dry the container completely before adding fresh product. Mixing old and new spices dilutes the flavour and increases the chances of contamination. Allow jars to air dry thoroughly before use to avoid trapping any residual moisture inside. This one small step helps keep your spices potent and clump-free for longer.

Bulk Buying Tips for Paleo Cooks

Buying spices in bulk can be cost-effective, but it does increase the risk of spoilage if you don’t store them correctly. Consider dividing bulk quantities into smaller airtight containers and storing the extras in the freezer or back of the pantry until needed. Only keep a small working jar in your spice rack, and refill as needed. This method also helps minimise exposure to light and heat — both of which degrade essential oils in spices, making them less effective in your cooking.

When to Replace Spices Entirely

Sometimes, no matter what you try, a spice just won’t revive. If it smells faint, looks faded, or tastes flat even after drying and grinding, it’s probably beyond saving. A spice that has turned musty or sour in scent may have absorbed too much moisture or begun to spoil. In these cases, it’s safer and more effective to replace it. Fresh, vibrant herbs and spices are crucial for paleo recipes where seasoning and wholefood flavours do the heavy lifting.

Simple Paleo Spice Blends to Make at Home

One of the best ways to ensure your spices stay fresh is to make your own blends in small batches. Here are a few paleo-friendly mixes that are easy to prepare and less likely to clump when stored correctly:

  • Simple Meat Rub: Paprika, cumin, garlic powder, salt, pepper, and dried oregano.
  • Herbed Roast Mix: Dried thyme, rosemary, sage, onion powder, and cracked black pepper.
  • Curry Base Blend: Turmeric, ground coriander, cumin, cinnamon, ginger, and fenugreek.

Mix only what you need and store in small, airtight jars in a dark, cool cupboard. This way, you're always using fresh, fragrant blends that bring out the best in your paleo meals.

Stay One Step Ahead of Clumping

With just a few simple adjustments, you can dramatically reduce spice waste in your paleo kitchen. Whether it's storing containers upside down, adding moisture absorbers, or transferring clumped powders into the oven for revival, the key is prevention. Keep your herbs and spices dry, cool, and well-sealed — and you’ll never have to chip away at a garlic powder boulder again. A little care goes a long way toward keeping your cooking full of flavour and your ingredients as vibrant as your lifestyle.
