Instructions
Preheat your oven to 350°Fand grease a baking dish or sheet pan.
Rinse the grouper fillets under cold water, then pat them dry with paper towels. Arrange them in a single layer on the prepared dish and season both sides with salt and pepper.
Combine the sour cream, Parmesan cheese, lemon juice and zest, onion powder, and hot sauce in a small bowl. Mix until smooth.
Spoon the sour cream mixture evenly over the fillets, spreading it out to cover the tops. Lightly dust each fillet with paprika.
Place the dish in the oven and bake for 15–20 minutes, depending on the thickness of your fillets. They’re done when the fish is opaque and easily flakes with a fork.
Optional: If you want your baked fillets to have a bit more color, place them under the broiler for a minute or two.
Garnish the baked grouper fillets with lemon wedges and fresh parsley, and serve immediately.
Notes
Pat the fish dry so the topping sticks and bakes evenly.Trim thicker tail pieces or group similar sizes together for even cooking.Sprinkle paprika by hand, not straight from the jar, for a more even dusting.Watch the broiler closely if finishing under heat; it can go from golden to scorched in seconds!Store any leftover baked grouper in an airtight container in the fridge for up to 2 days. Reheat gently in a 300°F oven until warmed through. Avoid microwaving if possible, as it can dry the fish out.
