The beauty of Coconut Lime Fish with Avocado Salsa is how these humble ingredients come together for something truly magical. Each ingredient is chosen to layer complexity and balance, giving you maximum flavor with minimal fuss. Here’s what you’ll need, along with just why each one matters.

- Canned coconut milk: The luscious backbone of the marinade, giving the fish richness while keeping it wonderfully moist.

- Lime zest: Don’t skip this! The zest provides intense lime aroma and depth that juice alone can’t replicate.
- Minced garlic: Adds a subtle pungency to balance the sweetness of the coconut milk.
- Olive oil: Helps emulsify the marinade and gives a silky mouthfeel to the baked dish.
- Salt: Brings all the flavors together and enhances every tropical note in the fish and salsa.
- Black pepper: Offers a gentle warmth; freshly ground is best for aroma.
- Chili powder: Gives a whiff of smokiness and just a whisper of heat to round out the marinade.
- Ripe avocados: The heart of your salsa, they deliver creaminess and gorgeous color contrast.
- Red onion: Lends a sharp crunch and beautiful purple hue to your topping.
- Jalapeño: Seeded for subtle fire—add more or less to match your spice preference.

- Salt (for salsa): Just a pinch brings all those bold salsa flavors into balance.
How to Make Coconut Lime Fish with Avocado Salsa
Step 1: Marinate the Fish
Start by whisking together the coconut milk, lime juice, lime zest, garlic, olive oil, salt, black pepper, and chili powder in a shallow dish. This dreamy mixture is what makes Coconut Lime Fish with Avocado Salsa so unforgettable—the coconut milk makes everything lush, while the lime and garlic keep things perky. Lay in your fish fillets, coating each generously. Allow to chill and marinate in the refrigerator for 20 to 30 minutes, so the flavors truly soak in.
Step 2: Prepare the Baking Dish
As your fish absorbs all those gorgeous flavors, preheat your oven to 400°F and lightly grease a baking dish. This prevents any sticking and ensures your fillets will lift out whole and beautiful. You can also prep your workstation for the salsa while the oven heats!
Step 3: Bake the Fish
Remove the fish from the marinade and nestle it snugly into your prepared baking dish. Pop it into the hot oven and bake for 12 to 15 minutes, or until the flesh flakes easily with a fork. You’ll notice the fish turning opaque and the kitchen filling with the most enticingly tropical aroma.
Step 4: Make the Avocado Salsa
While the fish cooks, toss together your diced avocado, red onion, minced jalapeño, chopped cilantro, lime juice, and a pinch of salt in a medium bowl. Be gentle when mixing—you want those creamy avocado chunks to keep their shape. This fresh, zingy salsa is the crowning jewel of Coconut Lime Fish with Avocado Salsa.
Step 5: Assemble and Serve
Once the fish is cooked through and temptingly flaky, it’s time for the fun part—serving! Spoon a generous mound of avocado salsa over each fillet and finish with an extra squeeze of lime juice. Watch as the salsa’s colors pop against the tender white fish, making every plate an edible tropical postcard.
How to Serve Coconut Lime Fish with Avocado Salsa

Garnishes
A final shower of extra cilantro leaves, a sprinkle of lime zest, or even some finely sliced scallions can add visual flair and a hit of fresh flavor. If you like a little crunch, scattered toasted coconut flakes or crispy shallots make a fun, textural contrast atop Coconut Lime Fish with Avocado Salsa.
Side Dishes
This sunny fish is incredibly versatile with sides. Coconut rice subtly echoes the marinade and complements the dish, while a peppery arugula salad adds some leafy lightness. Or, keep things simple with roasted sweet potatoes or quinoa for a wholesome, satisfying finish.
Creative Ways to Present
Elevate dinner party vibes by serving portions of Coconut Lime Fish with Avocado Salsa on a bed of shredded cabbage or inside lettuce cups for a playful, hand-held experience. For a festive platter, arrange sliced fish fillets with the salsa in the center and offer warm tortillas for easy fish-taco vibes.
Make Ahead and Storage
Storing Leftovers
Leftover Coconut Lime Fish with Avocado Salsa keeps best when the components are stored separately. Place cooked fish in a sealed container in the fridge for up to two days. The avocado salsa is best eaten fresh but will hold up (if covered tightly) for about a day without too much browning.
Freezing
While the baked fish on its own freezes nicely, avocado salsa does not—avocado just doesn’t love the freezer. Freeze any extra fish portions in airtight containers for up to one month. Plan to make fresh salsa when you’re ready to serve leftovers.
Reheating
Gently reheat the fish in a 300°F oven or in a covered skillet over low heat until warmed through. If you microwave, use short bursts to prevent drying. Always add fresh avocado salsa after reheating so the flavors stay bright and the textures contrast beautifully.
FAQs
What kind of fish works best for Coconut Lime Fish with Avocado Salsa?
Mild, sturdy white fish like cod, halibut, or tilapia are traditional picks. These varieties soak up the marinade beautifully and bake to flaky perfection. Feel free to try mahi-mahi or snapper if you’re feeling adventurous!
Can I make this recipe on the grill instead of baking?
Absolutely! Grilling adds a lovely smoky flavor that pairs so well with the coconut and lime. Oil your grill grates and cook the marinated fish over medium heat for about 3 to 4 minutes per side, depending on thickness.
How spicy does the salsa get with jalapeño?
With seeds removed, the jalapeño just adds a subtle kick and lots of fresh flavor. If you like things mild, use just half a pepper; if you crave heat, leave in some seeds or swap in a serrano for extra fire.
Is Coconut Lime Fish with Avocado Salsa gluten-free?
Yes, this entire dish is naturally gluten-free as written. It fits beautifully into gluten-free and even paleo-friendly diets, making it a great choice for guests with dietary restrictions.
How do I keep the avocado salsa from browning?
Tossing the diced avocado immediately with lime juice does wonders for preventing browning. If you need to prep ahead, press plastic wrap directly onto the salsa’s surface before storing in the fridge.
