- 1 lemon, sliced into thin rounds with the ends reserved
- 3 tablespoons olive oil
- 1 1/2 teaspoons minced garlic
- 1 1/2 teaspoons minced onion
- salt and ground black pepper to taste
- 1 filet steelhead trout
- Lightly oil the grate of your grill. Arrange lemon slices on the grate so they overlap slightly and form a shape slightly larger than your trout fillet.
- Preheat grill for medium heat to 350 degrees F (175 degrees C).
- Heat olive oil in a small skillet over medium-high heat.
- Saute garlic and onion in the hot oil until the garlic browns slightly, 2 to 3 minutes; season with salt and pepper. Squeeze the reserved lemon ends over the garlic mixture.
- Gently lay the trout fillet onto the lemons with the skin side down. Brush the garlic mixture over the top of the fish.
- Cook trout on hot grill until the fish flesh flakes easily with a fork, about 10 minutes.
