Cooking with fish is not only a quick and healthy way to prepare a delicious dinner but also an opportunity to explore a world of flavors. Whether you're using fresh or frozen fillets, turning them into a mouth - watering baked fish entrée can be a breeze with the right steps and a minimal - mess recipe.

First, let's talk about choosing the right fish. When it comes to fresh fish, look for clear, bright eyes, shiny skin, and a fresh, ocean - like smell. If you're opting for frozen fillets, make sure they are properly sealed and free of ice crystals. Popular fish choices for baking include salmon, cod, tilapia, and haddock. Each fish has its own unique flavor profile, so you can choose based on your personal preference.

Preparing the fish is the next crucial step. If you're using frozen fillets, thaw them in the refrigerator overnight or under cold running water for a quicker method. Once thawed, pat the fillets dry with a paper towel. This helps to remove any excess moisture and ensures a crispy exterior when baking. You can also score the skin side of the fish with a sharp knife in a cross - hatch pattern. This not only makes the fish look more appealing but also allows the seasonings to penetrate better.

Now, it's time to season the fish. There are countless seasoning options available, but a simple and classic combination is salt, pepper, and lemon juice. Sprinkle a generous amount of salt and pepper on both sides of the fillets. Squeeze fresh lemon juice over the top, which adds a bright and tangy flavor. You can also add other herbs and spices such as garlic powder, paprika, or dried thyme for an extra kick. For a more complex flavor, you can create a marinade using olive oil, soy sauce, and honey. Let the fish marinate in the refrigerator for at least 15 - 30 minutes to allow the flavors to meld.

When it comes to baking, preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or aluminum foil to make cleanup a breeze. Place the seasoned fillets on the baking sheet, skin - side down if applicable. You can arrange them in a single layer, leaving some space between each fillet for even cooking. If you want to add some extra moisture and flavor, you can place a few slices of lemon or a sprig of fresh herbs on top of the fish.

Bake the fish for about 12 - 15 minutes, depending on the thickness of the fillets. To check if the fish is cooked, insert a fork into the thickest part of the fillet. If the fish flakes easily and is opaque in the center, it's ready. Overcooking fish can make it dry and tough, so it's important to keep an eye on it. Once the fish is cooked, remove it from the oven and let it rest for a few minutes before serving. This allows the juices to redistribute and makes the fish even more tender.

Now, let's talk about a minimal - mess recipe. One great option is to make a foil packet. Cut a large piece of aluminum foil for each fillet. Place the seasoned fillet in the center of the foil. Add some chopped vegetables such as bell peppers, onions, and zucchini around the fish. Drizzle a little olive oil over the vegetables and season them with salt and pepper. Fold the foil over the fish and vegetables, creating a sealed packet. Place the packets on a baking sheet and bake in the preheated oven for about 15 - 20 minutes. The foil keeps the mess contained, and the steam created inside the packet helps to cook the fish and vegetables evenly.

You can serve the baked fish with a variety of sides. A simple green salad with a light vinaigrette is a refreshing option. Roasted potatoes or sweet potatoes also pair well with fish. For a more complete meal, you can make a side of quinoa or brown rice. Garnish the fish with some fresh parsley or cilantro for an added pop of color and flavor.

In conclusion, cooking with fish to create a baked fish entrée is a wonderful way to enjoy a quick and healthy dinner. By following these steps and trying out different seasonings and recipes, you can become a master at baking fish in no time. So, head to the grocery store, pick up some fresh or frozen fillets, and start cooking!
