Ingredients You’ll Need

This Garlic Butter Oven Baked Tilapia Recipe relies on fresh and aromatic ingredients that blend perfectly to enhance the delicate flavor of the tilapia. I recommend using fresh garlic and quality butter—the difference really shows here.

• Tilapia fillets: Choose fresh, firm fillets that are about the same size for even cooking.
• Salt and freshly ground black pepper: Classic seasoning to bring out the natural fish flavor.
• Paprika: Adds a hint of smokiness and a beautiful color.
• Dried thyme: Earthy herb that complements fish wonderfully.
• Dried oregano: Offers a subtle savory note.
• Butter: Use unsalted if possible, melting it gently to mix with the garlic and lemon.
• Garlic: Fresh minced garlic is key—avoid powders here for the best flavor.
• Lemon juice and lemon zest: They add brightness and a burst of citrus that cuts through the richness of the butter.
• Lemon slices: For garnish and extra zing.
• Red pepper flakes: Optional, for a little heat.
• Chopped fresh parsley: Adds freshness and color to finish.

Variations

I love that this Garlic Butter Oven Baked Tilapia Recipe is a perfect canvas for your own creativity. Over time, I’ve discovered a few tweaks that really make it my own, but feel free to experiment based on your preferences or what you have on hand.

• Herb Swap: I sometimes swap out thyme and oregano for fresh dill or basil—both add a bright, fresh twist that goes perfectly with fish.
• Spicy Kick: For heat lovers, I add extra red pepper flakes or a dash of cayenne pepper. Just a little gives a nice balance to the buttery sauce.
• Garlic Lovers: When hosting friends who love garlic as much as I do, I double the garlic for a seriously garlic-forward feast.
• Lemon Twist: Add a splash of white wine or a teaspoon of capers to the sauce for a tangy variation that’s always a hit.

How to Make Garlic Butter Oven Baked Tilapia Recipe

Step 1: Season Your Fish With Love

Start by preheating your oven to 400°F. While it’s warming up, pat your tilapia fillets dry with paper towels—this little trick helps the seasoning stick better and the fish bakes up nice and tender. Sprinkle salt, pepper, paprika, thyme, and oregano evenly over both sides of each fillet. I like to give each piece a gentle press to make sure the spices really adhere. Next, lay the fillets in a single layer in a 9×13 baking dish, making sure not to crowd them.

Step 2: Whisk Together the Garlic Butter Sauce

In a mixing bowl, whisk melted butter with freshly minced garlic, lemon juice, and lemon zest. This sauce is the star of the show—it adds richness, zing, and aroma that makes your kitchen smell incredible while the fish bakes. Pour this mixture evenly over the tilapia, coating each fillet with that tasty buttery garlic blend.

Step 3: Bake to Perfection

Pop the baking dish into the preheated oven and bake for 10 to 12 minutes. Here’s where you want to keep an eye on the fish so you don’t overcook it—tilapia is done when it easily flakes with a fork and looks opaque all the way through. Overcooking can make it dry, so start checking at 10 minutes if your fillets are thinner.

Step 4: Garnish and Serve

Once your fish is baked, sprinkle with red pepper flakes for a little kick, chopped fresh parsley for color and freshness, and arrange lemon slices on top or on the side for an extra citrusy pop. Serve right away, letting everyone dig into the melty garlic butter goodness.

Garnishes

I always reach for fresh chopped parsley to garnish this tilapia because it adds a bright, herbaceous flavor and a pop of green that makes the dish look as good as it tastes. Lemon slices scattered on top add freshness and a zesty visual appeal. And if I want a bit of heat, I sprinkle a pinch of red pepper flakes right before serving.

Side Dishes

My favorite sides here are roasted vegetables, like asparagus or Brussels sprouts, which complement the buttery fish perfectly. A light quinoa salad or garlic mashed potatoes also work beautifully to soak up all that garlic butter sauce. If you want to keep it super simple, steamed green beans or a crisp garden salad are always winners.

Creative Ways to Present

For a special occasion, I love plating this tilapia over a bed of lemon herb couscous, garnished with edible flowers or microgreens to impress guests. Stack the fillets slightly overlapping on a serving platter, drizzle any remaining garlic butter over the top, and surround with colorful roasted veggies for a restaurant-style presentation your guests will rave about.

Make Ahead and Storage

Storing Leftovers

I store leftover tilapia in an airtight container in the fridge for up to 2 days. The buttery garlic sauce holds up nicely, and the fish stays tender if you reheat it gently. Just be sure to cool the fish completely before sealing and refrigerating to keep freshness.

Freezing

While I don’t usually freeze cooked tilapia because I prefer the fresh texture, if you want to make this recipe ahead, you can freeze the raw seasoned fillets without sauce for up to 2 months. Then thaw overnight in the fridge before baking with the garlic butter sauce.

Reheating

To reheat, I gently warm leftovers in a low oven (around 300°F) for 8-10 minutes to keep the fish moist without drying it out. Microwave reheating tends to make fish rubbery, so the oven is my preferred method if you want leftovers tasting almost as good as fresh.
