How to Make Fish in Foil
Preheat: Begin by preheating your oven to 400 degrees F (200 degrees C). This step is essential for cooking the fish evenly and achieving that delicious flaky texture.
Prep: Rinse the trout fillets under cold water and pat them dry with a paper towel. Coat the fillets generously with olive oil, then sprinkle with garlic salt and black pepper for a flavorful kick.
Assemble: Lay each fillet on a large sheet of heavy-duty aluminum foil. Top them with the fresh jalapeño slices, and squeeze the juice from the lemon over the fillets, letting that vibrant flavor soak into the fish.
Garnish: Arrange additional lemon slices on top of each fillet. This will not only look pretty but will enhance the lemony zing that brings everything together beautifully.
Seal: Carefully fold and seal all edges of the foil to create enclosed packets. Place these packets on a baking sheet for ease of handling and to avoid any spills in your oven.
Bake: Pop the baking sheet into your preheated oven and bake for 15 to 20 minutes, or until the fish flakes easily with a fork. Timing may vary slightly depending on the thickness of your fillets, so keep an eye on them!
Optional: Serve with a sprinkle of fresh herbs for an added burst of flavor.
