Ingredients

• 1 pound Brussels sprouts
• 3 tablespoons Unsalted butter
• 1 tablespoon Olive oil
• 2 large Yellow onion
• 1 teaspoon Fresh thyme leaves
• 2 cloves Garlic
• 0.5 teaspoon Salt
• 0.25 teaspoon Black pepper
• 2 teaspoons Balsamic vinegar
• 0.5 cup Gruyère cheese
• 0.25 cup Panko breadcrumbs

Directions

Step 1

Preheat your oven to 400°F (200°C).

Step 2

Trim the ends of the Brussels sprouts and remove any yellow or damaged outer leaves. Slice them in half lengthwise.

Step 3

Thinly slice the yellow onions and mince the garlic cloves. Set aside.

Step 4

In a large oven-safe skillet, melt 2 tablespoons of butter with 1 tablespoon of olive oil over medium heat.

Step 5

Add the sliced onions to the skillet and sauté, stirring often, for 15-20 minutes until they are deeply caramelized. Lower the heat as needed to prevent burning.

Step 6

Stir in the fresh thyme, minced garlic, salt, and black pepper, cooking for an additional 1-2 minutes until fragrant.

Step 7

Add the Brussels sprouts to the skillet, cut side down, and sauté for 3-4 minutes until they begin to brown.

Step 8

Drizzle the balsamic vinegar over the Brussels sprouts and mix well to coat the vegetables evenly.

Step 9

Sprinkle the shredded Gruyère cheese over the Brussels sprouts and caramelized onions.

Step 10

Melt the remaining 1 tablespoon of butter and toss it with the panko breadcrumbs in a small bowl. Scatter the breadcrumbs evenly over the cheese layer.

Step 11

Transfer the skillet to the preheated oven and bake for 10-15 minutes, or until the cheese is melted and bubbling, and the breadcrumbs are golden brown.

Step 12

Remove the skillet from the oven and let the dish cool slightly before serving. Enjoy your French Onion Brussels Sprouts as a side or stand-alone dish!
