Step‑by‑Step Instructions for Baked Lemon Butter Tilapia
Step 1: Preheat Your Oven
Begin by preheating your oven to 425°F (220°C). This high temperature ensures that your Baked Lemon Butter Tilapia cooks quickly, yielding a deliciously flaky texture. While the oven heats up, take a moment to gather all your ingredients. The inviting aroma of melted butter and lemon will soon fill your kitchen!
Step 2: Prepare the Baking Dish
Lightly oil a 9×13 inch baking dish with nonstick spray or a little olive oil. This step is vital for ensuring that your tilapia fillets don’t stick to the dish while baking. The oil also helps create a lovely golden crust on the fish. Make sure the dish is placed on a stable surface as you continue preparing the rest of the dish.
Step 3: Mix the Butter Sauce
In a small bowl, combine the melted unsalted butter, minced garlic, fresh lemon juice, and lemon zest. Whisk these ingredients together until well combined. Letting the mixture sit for a couple of minutes will enhance the flavors, allowing the garlic to infuse into the butter, making your Baked Lemon Butter Tilapia even more delicious.
Step 4: Season the Tilapia
Place the tilapia fillets in the greased baking dish, ensuring they are evenly spaced. Generously season the fillets with kosher salt and freshly cracked black pepper, focusing on both sides. This simple seasoning will elevate the natural flavors of the fish and complement the zesty butter sauce that will be added next.
Step 5: Add the Butter Sauce
Drizzle the prepared butter sauce generously over the seasoned tilapia fillets. Make sure to cover each piece to ensure that every bite is packed with that rich, buttery flavor. The aroma will start to mingle with the freshness of lemon, creating an irresistible invitation to the dinner table.
Step 6: Bake the Tilapia
Carefully place the baking dish in the preheated oven and bake the tilapia for 10-12 minutes. Keep an eye on the fish as it cooks—the tilapia is done when it flakes easily with a fork and turns opaque in color. The golden crust that forms on top will signal that your Baked Lemon Butter Tilapia is just about ready to serve.
Step 7: Garnish & Serve
Once the tilapia is cooked to perfection, remove it from the oven and let it cool for just a minute. Serve immediately, garnished with freshly chopped parsley for an added splash of color and freshness. Pair it with your favorite sides for a delightful meal that will please the whole family!

Baked Lemon Butter Tilapia Recipe FAQs
How do I choose the best tilapia fillets?
Look for tilapia that is fresh with a bright, clean appearance. The flesh should be translucent and not have any dark spots or an off smell. If frozen, ensure the fish is properly sealed without any signs of freezer burn; opt for fillets that are firm to the touch and have a slight ocean scent.
What’s the best way to store leftover tilapia?
Absolutely! Store any leftover Baked Lemon Butter Tilapia in an airtight container in the refrigerator for up to 2 days. This keeps it fresh while preventing it from drying out. When you’re ready to reheat, gently warm it in the oven at 350°F (175°C) for about 10 minutes for the best texture.
Can I freeze baked tilapia? If so, how?
Yes, you can! To freeze, allow the tilapia to cool completely after baking. Wrap each fillet tightly in plastic wrap, placing a piece of parchment paper in between to prevent sticking. Then, wrap them in aluminum foil. Label your package and freeze for up to 3 months. When ready to enjoy, let it thaw in the refrigerator overnight before reheating.
What can I serve with my Baked Lemon Butter Tilapia?
Very! Pair this dish with a side of steamed vegetables, such as broccoli or asparagus, or a light salad for a refreshing contrast. You can also serve it over rice or quinoa to soak up the buttery lemon sauce. The options are endless!
Are there any dietary considerations I should be aware of?
This dish is relatively low in carbs and high in protein, making it suitable for most diets. However, if you or your loved ones have allergies, be cautious with the garlic and butter. You can easily substitute the butter with a dairy-free alternative, and garlic powder can replace fresh garlic for less risk of allergy.
Why did my tilapia not flake properly?
If your tilapia didn’t flake as expected, it may have been overcooked or undercooked. The key is to monitor the baking time; it should be cooked just until it turns opaque and flakes easily with a fork, generally around 10-12 minutes at 425°F (220°C). Always check it at the lower end of the baking time to avoid overcooking.
