Equipment

  • Large skillet or sauté pan
  • Wooden spoon or spatula
  • Chef’s knife
  • Cutting board
  • Measuring spoons
  • Measuring cup for wine or broth

Ingredients

  • 2 tablespoons olive oil
  • 2 tablespoons butter
  • 2 large yellow or sweet onions thinly sliced
  • 8 ounces mushrooms sliced (cremini, baby bella, or your choice)
  • 2 cloves garlic minced
  • ½ cup white wine or use water or broth
  • ½ teaspoon sea salt
  • 2 teaspoons fresh herbs such as thyme or rosemary, chopped

Instructions

  • Heat the olive oil and butter in a large skillet over medium heat until melted and shimmering.
  • Add the sliced onions and cook, stirring occasionally, until they begin to soften and turn golden, about 10–15 minutes.
  • Stir in the mushrooms and continue to cook for another 8–10 minutes, until the mushrooms have released their moisture and everything is nicely browned.
  • Add the minced garlic and cook for another minute until fragrant.
  • Pour in the white wine (or your liquid of choice) to deglaze the pan, scraping up any browned bits from the bottom. Let it simmer until most of the liquid has evaporated, continuing to stir and encourage caramelization.
  • Season with sea salt and stir in the fresh herbs.
