Why Coconut Seafood Soup is a Paleo Favourite
Following a Paleo lifestyle means focusing on nutrient-dense, whole foods that support your health. This soup delivers on every front. Coconut milk provides healthy fats and adds a luscious, creamy texture without needing any dairy. Seafood is an excellent source of lean protein, omega-3 fatty acids, and essential minerals like zinc and selenium.
The combination of herbs and spices such as fresh coriander, lime, ginger, and chilli not only adds complex flavour but also boosts the immune system and aids digestion. It’s no surprise this soup has become a firm favourite in many Paleo households.
Tips for Choosing the Best Seafood
When making this soup, choosing fresh, high-quality seafood makes all the difference. Aim to source sustainably caught fish and shellfish where possible. Prawns, scallops, calamari, and firm white fish such as snapper or barramundi all work beautifully. If you’re short on time, frozen seafood can also be a good option—just make sure it’s fully thawed and drained before cooking.
You might also consider buying a seafood marinara mix for convenience. Look for one that doesn’t contain any added fillers or preservatives.
Customising the Flavour Profile
This dish can be tailored to suit your individual palate. If you love spice, leave the seeds in the chilli or add an extra one. For a milder version, use just half a chilli or swap it for a dash of chilli flakes. You could also add extra garlic or ginger if you like a bolder, more aromatic soup base.
To make it even more filling, consider adding sliced mushrooms, julienned carrots, or baby spinach just before serving. These additions complement the flavours well and bring extra nutrients to the dish.
Perfect Pairings
While this soup is satisfying on its own, it can also be served as a starter or part of a larger meal. Try pairing it with a crisp Thai-style salad or grilled skewers of lemongrass chicken or herbed pork. A wedge of lime on the side never goes astray and enhances the fresh flavours.
If you're serving the soup as a main, a side of steamed Asian greens with garlic and a drizzle of sesame oil makes an excellent addition. Keep it Paleo by skipping the rice or noodles, and lean into the wholesome simplicity of the ingredients.
Make-Ahead and Freezing Options
Although best served fresh, this soup can be made ahead of time if necessary. Simply prepare the soup base up to the point before adding the seafood. Store it in an airtight container in the fridge for up to two days. When ready to serve, reheat the base and add your seafood just before serving to keep it tender and perfectly cooked.
Storage Tips:
Any leftovers can be frozen in small batches immediately, ready to reheat for a quick and easy lunch another time. Use freezer-safe containers or silicone pouches for easy portioning. When reheating, bring the soup to a gentle simmer on the stovetop rather than microwaving to prevent the seafood from becoming rubbery.

Frequently Asked Questions
Can I use chicken or another protein instead of seafood?
Absolutely. While seafood gives this soup its signature flavour, chicken or even tofu (if you tolerate it) can be used. Just adjust the cooking time to ensure the protein is fully cooked through.
Is this soup spicy?
It can be, but you’re in control of the heat. Start with a small amount of chilli and adjust to your taste. Remember, you can always add more, but you can’t take it away.
What can I do if I don't have fresh herbs?
Fresh herbs do offer the best flavour, but if you only have dried, use smaller quantities. For example, use a teaspoon of dried coriander or basil in place of a tablespoon of fresh.
Can I add noodles?
If you follow a strict Paleo diet, traditional noodles are out. However, spiralised zucchini or kelp noodles can be added for a similar experience without breaking the rules.
