Why This Recipe Works

The cook-in-foil method is incredibly easy because there is very minimalcleanup. I’m talking done-in-25-minutes easy. Because the fish is wrapped in foil, the fish is steamed, retaining the moisture, and rendering juicy and tender meat.

Ingredients

  • Steelhead trout filet: Look for a full longer portion of trout that hasn’t been cut into individual pieces. You can remove the skin but it’s optional. Once the fish is done cooking, the skin will easily separate from the meat. Salmon makes a great substitute.
  • Butter: butter helps form the paste that coats the whole fish. It adds buttery flavor and texture to every bite. Use salted or unsalted. If using unsalted, you may need an extra pinch of salt on the fish.
  • Lemon: I like to reserve lemon for just before serving as well. It’s hard to beat a fresh squeeze of lemon on finished fish. For even more flavor, incorporate lemon zest.
  • Garlic: fresh garlic is a must. Do not substitute with anything pre-minced or garlic powder for best results. A microphone is my favorite way to finely mince fresh garlic into a paste.
  • Parsley: both parsley and basil are delicious herbs for this recipe. I always suggest fresh over anything dried for best results. The measurements of fresh ingr

How to Cook Steelhead Trout in Foil

Step 1.

Preheat oven to 375°F. Soften butter in a microwave-safe bowl. Stir in fresh minced garlic and parsley. Set aside. This can be made ahead so the flavors meld.

Step 2.

Roll out a sheet of aluminum foil that is roughly 8 inches longer than the filet. If your filet is larger/wider, you can crimp together two pieces of foil so you have more foil to work with. Spray with cooking oil.

Step 3.

Place the trout filet in the center of the foil. Fold up all 4 sides of the foil. Season trout liberally with salt and then squeeze juice from half a lemon over the fish.

Step 4.

Spread the butter mix over the trout until evenly coated with a thin layer. You can alternatively melt the butter and pour it over the fish. Top with a sliced lemon wheel.

Step 5.

Fold the long sides of the foil over the trout, covering it completely, and seal it tightly. Fold the ends over and seal into a closed packet. Place directly on an oven rack or on a baking sheet and bake until cooked fully through (about 15-20 minutes).

Step 6.

Optional step: Open the foil exposing the top of the trout and broil for the last 1-2 minutes, for a browned top.

Expert Tips

  • There are a few methods when it comes to covering the fish in garlic butter. If you soften the butter into a soft paste, you can evenly spread it on top of the filet. It’s a great way to ensure the fish is entirely covered. Melting the butter entirely works, too.
  • This foil method will work for just about any fish and any topping. I’ve done it with cod, haddock, salmon, and of course trout. If your fish is on the larger side, you can crimp together two pieces of foil so you have a larger surface area.
