Ingredients
Tilapia Fillets: This is the star of the dish. Mild and flaky, tilapia is the perfect canvas for soaking up buttery garlic flavors without overpowering them.
Butter: Essential for that rich, comforting base. When melted in the oven, it envelopes the fish and infuses every bite with warmth.
Garlic: Freshly minced garlic brings the bold, aromatic essence that elevates this simple dish to something irresistible.
Lemon Juice: A squeeze of lemon balances the richness of the butter and brightens the entire flavor profile.
Paprika: Just a pinch gives the fish a gentle smoky undertone and an appealing hint of color.
Salt and Pepper: These staples are key to highlighting the natural taste of the tilapia.
Fresh Parsley (Optional): Adds a pop of freshness and a vibrant green touch right before serving.
How to Make Garlic Butter Oven Baked Tilapia
Step 1: Preheat and Prepare
Preheat your oven to 400°F (200°C). Lightly grease a baking dish or line it with parchment paper for easy cleanup.
Step 2: Make the Garlic Butter Mixture
In a small saucepan or microwave-safe bowl, melt the butter. Stir in the minced garlic, lemon juice, paprika, salt, and pepper. Mix well until combined.
Step 3: Arrange the Tilapia
Place the tilapia fillets in the prepared baking dish in a single layer. Pour the garlic butter mixture evenly over the fillets, making sure they are well-coated.
Step 4: Bake to Perfection
Bake uncovered for 12 to 15 minutes, or until the fish flakes easily with a fork and is opaque in the center.
Step 5: Garnish and Serve
Remove from the oven and, if desired, sprinkle with chopped fresh parsley. Serve immediately with your favorite side dishes.
Recipe Variations and Possible Substitutions
If tilapia isn’t available or isn’t your preference, you can easily swap it with cod, haddock, or even salmon. These white fish varieties maintain a mild flavor and bake well in the same buttery garlic blend. For a dairy-free twist, use olive oil or vegan butter instead of traditional butter. Want to add some heat? A sprinkle of crushed red pepper or a dash of cayenne will do the trick. And if you’re a fan of herbs, try mixing in fresh dill or thyme to give it a different herbal note.
Serving and Pairing Suggestions
Garlic Butter Oven Baked Tilapia pairs beautifully with both light and hearty sides. I often serve it with garlic mashed potatoes or a buttery rice pilaf to complement the richness of the fish. For a low-carb option, roasted zucchini or a crisp green salad does the trick. If you’re planning a full dinner spread, add some crusty bread to mop up every drop of that golden garlic butter. A chilled glass of Sauvignon Blanc or a citrusy sparkling water makes an excellent beverage match.



Storage and Reheating Tips
Store leftover baked tilapia in an airtight container in the refrigerator for up to 2 days. When reheating, place it in a covered oven-safe dish and warm at 300°F (150°C) until just heated through to avoid drying out the fillets. You can also reheat it gently in the microwave at medium power. Avoid freezing, as the texture of the fish can change and become watery upon thawing.
