Karamelizovaná červená cibulka

Preparation Peel the red onions and slice them into 1/4-inch thick rounds.

Caramelizing the Onions In a large skillet, heat the butter and olive oil over medium heat. Add the sliced red onions and cook, stirring occasionally, for 15-20 minutes or until the onions are deep golden brown and caramelized.

Making the Glaze Once the onions are caramelized, pour in the balsamic vinegar and sprinkle the brown sugar over the onions. Stir well to combine. Allow the mixture to simmer for an additional 5-7 minutes, or until the glaze thickens and coats the onions.

Finishing Touches Season the caramelized onions with salt and pepper to taste. Transfer to a serving dish and garnish with fresh thyme leaves. Serve as a side dish or as a topping for burgers, steaks, or salads.
