Cooking grouper in the oven gives you lots of flexibility to add different seasonings and ingredients. Try Mediterranean flavors like lemon and oregano or Caribbean inspired tropical fruit salsas. The possibilities are endless.

Oven-baked fish has a light, fresh taste that pairs well with a variety of sides. Round out your meal with rice, roasted veggies or a fresh salad.

Choosing Grouper Fillets for Baking

You can find grouper fillets fresh or frozen at most grocery stores and fish markets. When buying, look for:

• Meaty, thick fillets at least 1 inch thick. Thinner pieces may dry out.

• Shiny, translucent flesh without discoloration.

• Firm, resilient texture that springs back when touched.

• Mild, sweet scent, not overly fishy.

• Bright red gills if purchasing a whole fish.

For even cooking, choose fillets that are similarly sized and uniformly thick. Large fillets may need longer cook times.

Thawed frozen grouper works just as well as fresh. Defrost frozen fillets gradually in the refrigerator overnight. Don’t refreeze fish after it has thawed.

Preparing Grouper Fillets for Oven Baking

Follow these simple steps for preparing flawless oven-baked grouper:

• Rinse fillets under cold water and pat dry thoroughly with paper towels. Make sure no moisture remains on the fish.

• Brush both sides of the fillets lightly with olive oil or melted butter. This helps keep the fish moist and prevents sticking.

• Season as desired. Good options include salt, pepper, paprika, garlic powder, lemon pepper and Italian seasoning.

• For stronger flavors, you can optionally marinate the fish for 15-30 minutes before baking. Try marinades with citrus juice, herbs, garlic and olive oil.

• Line a rimmed baking sheet with parchment paper or foil for easy cleanup. Arrange fillets in a single layer with space between each piece.

How to Bake Grouper Fillets to Perfection

Follow these simple oven baking instructions for flawlessly cooked fish:

• Preheat oven to 400°F.

• Bake for 10-12 minutes per 1-inch thickness of fish. Check at the minimum time to avoid overcooking.

• Fish is done when it turns opaque and flakes easily with a fork. The flesh should look moist, not dried out.

• Baking time varies based on thickness. Thinner fillets may take only 8-10 minutes while thicker pieces bake for 12-15 minutes. Watch carefully to prevent over or undercooking.

• For food safety, verify fish reaches an internal temperature of 145°F. Use an instant-read thermometer to check thickness and ensure doneness.

• Turn oven to broil for 1-2 minutes at the end for lightly crisped, browned tops if desired. Watch carefully to avoid burning.
