Step‑by‑Step Instructions for Baked Tilapia In Lemon Garlic Sauce
Step 1: Prep the Marinade
In a medium bowl, combine melted unsalted butter, minced garlic, fresh lemon juice, Italian seasoning, smoked paprika, onion powder, salt, and black pepper. Stir well until the mixture is fully blended, creating a fragrant marinade that will infuse your tilapia with delicious flavor. This zesty concoction sets the stage for your Baked Tilapia in Lemon Garlic Sauce.
Step 2: Prepare the Oven
Preheat your oven to 200°C (400°F). While it’s heating, adjust the oven rack to the upper third position to ensure a perfect cooking environment. This will help achieve a beautifully golden crust on your tilapia while keeping it moist inside. The enticing aroma of lemon and garlic will soon fill your kitchen!
Step 3: Arrange the Baking Tray
Line a baking tray with parchment paper for easy cleanup. Spread the sliced onions and bell peppers in a single layer across the tray, allowing for optimal roasting. This colorful base not only adds nutrition but also enhances the presentation of your baked tilapia as it cooks, soaking up all the delicious juices from the fish.
Step 4: Apply Marinade
Position the tilapia fillets on top of the arranged vegetables. Generously brush or spoon the marinade over both sides of each fillet, ensuring they are well-coated. Top the fish with fresh lemon slices for an added burst of citrus flavor and an appealing visual touch, which complements your Baked Tilapia in Lemon Garlic Sauce.
Step 5: Bake
Carefully place the baking tray in the preheated oven and bake for 10-12 minutes. The tilapia is done when it appears flaky and opaque, a clear sign that the fish has reached the perfect level of doneness. The vibrant veggies will also caramelize slightly, enhancing their natural sweetness.
Step 6: Serve and Savor
Once baked, remove the tray from the oven and let it rest for a minute. Serve your Baked Tilapia in Lemon Garlic Sauce over a bed of quinoa or with a side of sautéed greens. Don’t forget to drizzle some of the extra lemon butter sauce from the tray over each serving for an extra touch of flavor. Enjoy your delightful, healthy meal!

Baked Tilapia in Lemon Garlic Sauce Recipe FAQs
What kind of tilapia should I use?
I recommend using fresh or fully thawed tilapia fillets for the best flavor and texture. If opting for frozen fillets, ensure they’re completely thawed and patted dry to help the marinade adhere better and avoid watering down the sauce.
How should I store leftovers?
Store any leftovers in an airtight container in the refrigerator for up to 2 days. This keeps the fish fresh while preventing it from absorbing odors from other foods. When you’re ready to enjoy, simply reheat gently to maintain its delicious taste.
Can I freeze the baked tilapia?
Absolutely! You can freeze the unbaked marinated tilapia. Place it in a freezer-safe bag, ensuring to remove excess air, and you can enjoy it for up to 3 months. To cook, just thaw in the refrigerator overnight—then bake as usual.
Why is my tilapia coming out dry?
If your tilapia is turning out dry, it could be due to overbaking. Keep a close eye on it, and aim for an internal temperature of 145°F (63°C). Additionally, ensuring the fish is well-coated with marinade before baking helps retain moisture.
Is this recipe pet-friendly?
While tilapia is generally safe for dogs in small amounts, avoid adding garlic or excessive seasoning. Always consult your veterinarian before introducing any new food to your pet’s diet to ensure it aligns with their health needs.
