- Tilapia fillets: Mild, tender, and quick-cooking, tilapia is the perfect canvas for bold garlic butter flavors.
- Unsalted butter (melted): Butter adds rich flavor and helps keep the fish moist and luscious in the oven.
- Garlic (minced): Fresh garlic infuses the dish with deep savory notes—don’t skimp on this aromatic essential.
- Lemon juice: A splash brightens the entire dish and keeps the flavors lively and fresh.
- Paprika: Adds a hint of warmth and a subtle, earthy color to the fillets.
- Salt: Just the right amount to balance and enhance every ingredient.

How to Make Garlic Butter Oven Baked Tilapia
Step 1: Prepare Your Oven and Baking Sheet
Start by preheating your oven to 400°F (200°C). This high heat means the fish cooks fast and evenly, so you’ll get that perfect moist and flaky texture. Line a baking sheet with parchment paper for effortless cleanup, or lightly grease it if you prefer. Arrange the tilapia fillets in a single layer—no overlap, so each piece bakes perfectly through.
Step 2: Make the Garlic Butter Sauce
In a small bowl, simply mix together your melted butter, minced garlic, fresh lemon juice, paprika, salt, and black pepper. This golden elixir does all the heavy lifting for flavor. Make sure the butter is fully melted so it mixes smoothly with the garlic and spices—each ingredient should shine through.
Step 3: Coat the Fish
Spoon or brush the garlic butter mixture generously over each tilapia fillet. The goal is to coat every surface so the flavors soak in while baking. If you’re feeling fancy, massage the sauce in a bit with a spoon or your fingers—you really can’t go wrong here!
Step 4: Bake to Perfection
Slide your baking sheet into the oven and bake the fish for 10 to 12 minutes. You’ll know it’s done when the tilapia flakes easily with a fork and looks opaque. Try not to overbake—this fish is delicate and cooks fast, so keep an eye on it.
Step 5: Garnish and Serve
Take the fillets out of the oven and immediately sprinkle on the chopped parsley for a burst of color and freshness. Serve the Garlic Butter Oven Baked Tilapia hot, with lemon slices on the side so everyone can add a bright, zesty squeeze just before digging in.

Garnishes
A handful of chopped fresh parsley looks beautiful scattered over the finished plate, and don’t forget those lemon slices. If you have a few extra herbs on hand, like dill or chives, a light sprinkle can take the flavors to another level. A pinch of extra paprika also gives a lovely pop of color.
Side Dishes
Garlic Butter Oven Baked Tilapia is super versatile—think fluffy rice, buttery mashed potatoes, or even quinoa for something a bit heartier. For veggies, go simple: steamed green beans, roasted broccoli, or a crisp salad all work wonders alongside the buttery tilapia.
Creative Ways to Present
For a dinner party twist, try serving the tilapia fillets over a bed of wilted spinach, or tuck them into warm tortillas with slaw for a zesty fish taco night. Even layering them in a hearty grain bowl with roasted veggies makes for a show-stopping weekday meal.
Make Ahead and Storage
Storing Leftovers
If you have any leftover Garlic Butter Oven Baked Tilapia, place the cooled fillets in an airtight container and store them in the fridge. They’ll stay fresh and tasty for up to two days, making them perfect for a speedy lunch or quick dinner the next day.
Freezing
Tilapia freezes well—just let the cooked fish cool completely before wrapping each fillet tightly in plastic wrap or foil. Store them in a freezer-safe bag or container for up to one month. Thaw overnight in the refrigerator before reheating for best results.
Reheating
To gently reheat Garlic Butter Oven Baked Tilapia, place the fillets on a baking sheet, splash a few drops of water or lemon juice over them, and warm in a 300°F oven for about 8–10 minutes. This helps the fish stay moist and prevents it from drying out. Avoid microwaving if you can—it can make the fish rubbery.
FAQs
Can I use frozen tilapia fillets for this recipe?
Yes, but make sure to thaw the fillets completely and pat them dry before baking. Excess moisture from frozen fish can dilute the flavors and prevent the butter sauce from sticking properly.
What can I substitute for tilapia?
If you can’t find tilapia, look for other mild, white fish like cod or haddock. These types work beautifully with the garlic butter sauce and cook in about the same amount of time.
Can I make Garlic Butter Oven Baked Tilapia dairy-free?
Absolutely! Just swap the butter for a dairy-free alternative, such as vegan margarine or olive oil. The garlic and lemon still shine and the fish bakes up deliciously moist.
Is this recipe gluten-free?
Yes, Garlic Butter Oven Baked Tilapia is naturally gluten-free, as long as you check that your spices and seasonings are certified gluten-free. It’s perfect for those with gluten sensitivities or anyone looking for a wholesome meal.
How do I know when the tilapia is done baking?
Your fish is ready when it looks opaque and flakes apart easily with a fork. The baking time is short, so start checking it after 10 minutes to ensure it stays perfectly moist and tender.
Final Thoughts
If you’re after a dish that’s fast, flavorful, and absolutely fuss-free, you’ll cherish making Garlic Butter Oven Baked Tilapia. It’s a meal that feels like a special treat, no matter how busy your day has been.
