Ingredients
You only need a few basic ingredients to make Garlic Butter Tilapia. These keep the flavors simple and delicious:

- Tilapia fillets: Use fresh or fully thawed fillets. Tilapia’s mild flavor soaks up seasonings well.
- Onion powder and paprika: Onion powder adds savory depth; paprika brings color and warmth.
- Crushed red pepper flakes: For a touch of heat (optional).
- Unsalted butter: Melted and mixed with garlic to coat the fish.
- Minced garlic: Fresh garlic gives the best flavor—about 1 tablespoon (roughly 3 cloves).
- Salt and pepper: To taste.
- Garnishes: Fresh minced parsley (and dill if you like) and lemon wedges for serving.
Is Tilapia Healthy?
Most tilapia sold is farm-raised. Responsibly farmed tilapia can be a healthy choice—it’s a good source of lean protein and contains omega-3 fatty acids. When possible, choose responsibly raised fish for the best nutrition and environmental practices.

Substitutions and Variations
Small swaps let you adapt this recipe to what you have on hand:
- Different fish: Use cod, flounder, halibut, red snapper, or whiting.
- Seasonings: Try all-purpose, Cajun, Italian seasoning, or Old Bay for a different flavor profile.
- Fat: Replace half the butter with olive oil for a lighter option.
- Vegetables: Roast asparagus, mushrooms, or bell peppers alongside the fish.
- Citrus: Add lemon or lime juice or zest to brighten the dish.
If you prefer stovetop preparations, consider pan-seared tilapia or lemon butter tilapia for similar quick dinners.
How To Make Garlic Butter Tilapia
This is a very straightforward recipe—prep, season, pour butter mixture, then bake. Steps at a glance:
1. Pat the fillets dry and season both sides with salt, pepper, onion powder, paprika, and red pepper flakes.

2. Whisk melted butter with minced garlic, then pour the mixture over the seasoned fillets so they’re evenly coated.


3. Bake at 400°F (200°C) for about 10–12 minutes, until the fish flakes easily with a fork. Garnish with fresh herbs and serve warm.

Tip: Fish is done when it flakes easily with a fork. If using an instant-read thermometer, the internal temperature should reach 145°F (63°C).
How To Bake Tilapia From Frozen
You can bake tilapia from frozen; expect a longer cook time. Place frozen seasoned fillets in a greased baking dish and bake at 400°F (200°C) for about 20 minutes, or until the fish flakes easily.
Storage
- Leftovers: Refrigerate in an airtight container for up to 3 days.
- Freezer: Freeze cooked tilapia for up to 3 months in an airtight container.
- Reheating: Reheat in a 350°F (180°C) oven until warmed through, or use the microwave or a skillet. Note reheated fish may be less flaky.
Expert Tip
For a touch of color and extra flavor, broil the tilapia for 1–2 minutes at the end of cooking—watch it closely to prevent burning.

Recipe FAQs
Tilapia pairs well with vegetables, rice, mashed potatoes, salads, and many other side dishes.
Tilapia absorbs flavors well, so a marinade can help, but it’s not required. Simply seasoning and cooking will still yield a tasty result.
No—there’s no need to flip tilapia while baking.
Thaw fillets overnight in the refrigerator, or accelerate thawing by placing them in cool water and changing the water every 30 minutes until thawed.
