📝 Instructions

9 steps
1

Peel and thinly slice the red onions. Mince the garlic cloves.

2

Pat the trout fillets dry with paper towels, and season both sides with 1 teaspoon of salt and 1 teaspoon of black pepper.

3

Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the sliced red onions and cook for 8–10 minutes, stirring occasionally, until they begin to soften and caramelize.

4

Add the minced garlic and fresh thyme to the onions, and cook for an additional 1–2 minutes until fragrant.

5

Deglaze the skillet by adding the optional white wine (or 2 tablespoons of water if not using wine) to the onion mixture. Stir well, scraping the bottom of the pan to release any browned bits. Let it simmer for a minute, then transfer the onion mixture to a plate and set aside.

6

In the same skillet, heat the remaining 1 tablespoon of olive oil and 1 tablespoon of butter over medium heat. Place the trout fillets skin-side down and cook for 3–4 minutes, until the skin becomes crispy.

7

Flip the trout fillets gently and cook for another 2–3 minutes, or until the fish is opaque and flakes easily with a fork. Add the remaining 1 tablespoon of butter to the skillet as the fillets finish cooking and baste the fish with the melted butter using a spoon.

8

Return the caramelized onions to the skillet, spooning them around and over the trout fillets. Squeeze fresh lemon juice over the fish and garnish with additional thyme if desired.

9

Serve immediately with your favorite side dish, such as roasted vegetables or a light salad.
