Ingredients For Baked Fish Fillets Recipe
Fish fillets: White fish fillets such as cod, haddock, or tilapia are ideal for this recipe. They are mild in flavor and cook quickly.
Olive oil: This healthy fat adds richness and helps keep the fish moist during baking.
Salt: Essential for seasoning and enhancing the natural flavors of the fish.
Black pepper: Freshly ground black pepper adds a subtle heat and depth of flavor.
Lemon: Sliced lemon not only adds a bright, zesty flavor but also helps to keep the fish moist and tender.
Technique Tip for This Recipe
To enhance the flavor of your fish fillets, consider marinating them for about 15-30 minutes before baking. A simple marinade of olive oil, lemon juice, garlic, and fresh herbs like dill or parsley can infuse the fish with additional layers of taste. This extra step can make a significant difference, especially if you're using a mild white fish.
