Garlic Butter Oven Baked Tilapia

Save this recipe on:

I can still remember the first time I pulled a bubbling dish of garlic butter oven baked tilapia from the oven—the aroma alone was enough to make everyone rush to the kitchen. The garlic-infused butter, slightly caramelized around the edges, mingled perfectly with the delicate, flaky tilapia. It was love at first bite. Since then, this recipe has become one of my favorite go-tos when I want a quick yet flavor-packed dinner.

What I love most is how simple it is to prepare. Even after a long day, I can throw everything together in under 10 minutes and still end up with something that tastes like I spent hours in the kitchen. Plus, it’s naturally low-carb and gluten-free, making it ideal when I want something a bit lighter but still satisfying.

I’ve even served this to friends who claimed they weren’t “fish people,” and they always leave with the recipe in hand. The combination of butter, garlic, lemon juice, and gentle herbs really lets the mild flavor of tilapia shine. It pairs beautifully with rice, steamed vegetables, or even tucked inside a soft taco shell for a quick fish taco night.

Ingredients

Tilapia Fillets: Mild, flaky, and perfect for absorbing all the buttery, garlicky goodness. Fresh or thawed frozen fillets both work beautifully.

Butter: The base of our sauce, butter adds richness and depth that brings all the other flavors together.

Garlic: Fresh minced garlic is essential—it infuses the butter with bold aroma and flavor.

Lemon Juice: Adds brightness and cuts through the richness of the butter, enhancing the fish’s natural flavor.

Paprika: Gives a subtle warmth and color to the dish.

Dried Parsley or Italian Seasoning: Offers a gentle herbal note that pairs nicely with garlic and lemon.

Salt and Pepper: Essential for bringing out all the other flavors.

How to Make Garlic Butter Oven Baked Tilapia

Step 1: Preheat and Prep

Preheat your oven to 400°F (200°C). Lightly grease a baking dish with oil or nonstick spray. Arrange your tilapia fillets in a single layer.

Step 2: Make the Garlic Butter Sauce

In a small saucepan or microwave-safe bowl, melt the butter. Stir in the minced garlic, lemon juice, paprika, parsley (or seasoning), salt, and pepper. Mix until well combined.

Step 3: Pour and Coat

Evenly pour the garlic butter sauce over the tilapia fillets, using a spoon to ensure each piece is well coated.

Step 4: Bake to Perfection

Place the baking dish in the oven and bake for 12 to 15 minutes, or until the fish flakes easily with a fork. If you’d like a slight golden top, broil for an additional 2-3 minutes.

Step 5: Serve Immediately

Remove from the oven and serve hot with your favorite sides—steamed rice, roasted vegetables, or a crisp salad are all excellent choices.

Recipe Variations and Possible Substitutions

If you’re missing an ingredient or want to switch things up, this recipe is flexible. You can use olive oil instead of butter for a dairy-free option, or swap in lime juice for a citrus twist. For extra flavor, try adding grated Parmesan cheese or crushed red pepper flakes to the sauce. If you don’t have tilapia, other white fish like cod, haddock, or flounder also work well.

You can also incorporate fresh herbs like thyme or basil if you have them on hand. And for a heartier version, lay the fillets over thinly sliced potatoes or zucchini before baking to soak up the juices.

Serving and Pairing Suggestions

Garlic butter oven baked tilapia is delicious on its own but even better with a few thoughtful sides. I love serving it with jasmine rice or mashed potatoes to soak up the buttery sauce. Roasted asparagus, steamed broccoli, or a fresh cucumber tomato salad provide a refreshing contrast.

For a more filling dinner, try pairing it with garlic bread or a creamy pasta dish. And if you’re feeling fancy, a crisp white wine like Sauvignon Blanc complements the lemony, buttery notes beautifully.

Storage and Reheating Tips

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place the fish in an oven-safe dish, cover with foil, and warm at 300°F until heated through. Avoid microwaving for too long to keep the texture flaky and moist.

You can also freeze cooked tilapia for up to 2 months. Just be sure to thaw it in the fridge overnight before reheating.
