2 lemons
Cooking spray
4 (6-ounce) red snapper or other firm white fish fillets
1/4 teaspoon salt
1/4 teaspoon paprika
1/4 teaspoon black pepper
2 tablespoons unsalted butter, softened
1½ teaspoons chopped fresh herbs (such as rosemary, thyme, basil, or parsley)
Fresh herb sprigs (optional)
Preheat oven to 425°F.
Cut 1 lemon into 8 slices. Place slices, in pairs, on a rimmed baking sheet coated with cooking spray. Grate remaining lemon to get 1 teaspoon lemon rind; set aside. Reserve lemon for another use.
Place 1 fillet on top of each pair of lemon slices. Combine salt, paprika, and pepper; sprinkle evenly over fish. Bake at 425° for 13 minutes or until fish flakes easily when tested with a fork or until desired degree of doneness.
While fish bakes, combine reserved lemon rind, butter, and herbs in a small bowl.
Place fish and lemon slices on individual serving plates; top each fillet with herbed butter, spreading to melt, if desired. Garnish with herb sprigs, if desired.
