Why Cook Fish in Foil?

Cooking fish in foil has several advantages:

• Even Cooking: The foil acts as a protective barrier, preventing the fish from drying out and ensuring even cooking.
• Flavor Retention: Foil helps to preserve the natural flavors and nutrients, making your dish more aromatic and nutrient-dense.
• Easy Clean-Up: The foil catches all the juices, reducing mess and making clean-up a breeze.

Types of Fish Best Suited for Foil Cooking

Not all types of fish are created equal when it comes to foil cooking. Here are some that work exceptionally well:

• Salmon: Its rich, fatty texture holds up well in foil.
• Cod: This white fish is perfect for absorbing flavors.
• Tilapia: A budget-friendly option that cooks quickly.
• Trout: Another flavorful fish that steams well in foil.

Step-by-Step Guide

Prepare Your Fish

Start by rinsing the fish under cold water and patting it dry with paper towels. This ensures that your fish will cook evenly.

Seasoning

Season the fish with salt, pepper, and your favorite herbs or spices. Some popular choices include dill, garlic, and lemon slices. Feel free to get creative and use a marinade for extra flavor.

Wrapping the Fish

Place the fish in the center of a large piece of foil. If youre grilling multiple fillets, make sure they are spaced out evenly. You can also add vegetables like bell peppers, onions, or asparagus for a one-foil dinner solution.

Baking

Preheat your oven to 400F (200C). Once the oven is ready, place the foil packets on a baking sheet and bake for 15-20 minutes for small fillets. Larger fillets or whole fish may need 25-30 minutes. The fish is done when it flakes easily with a fork.

Timing for Different Types of Fish

The cooking time can vary depending on the type and thickness of the fish. Here are some general guidelines:

• Salmon Fillets: 15-20 minutes
• Whole Trout: 25-30 minutes
• Cod Fillets: 15-20 minutes
• Tilapia Fillets: 10-15 minutes

Always check the fish a few minutes before the end of the cooking time to ensure it doesnt overcook.
