A simple and flavorful side dish of sautéed mushrooms and onions cooked with garlic, thyme, and a blend of butter and olive oil for a rich, savory taste. Perfect for complementing main courses or enhancing breakfast dishes.

Ingredients

Main Ingredients

  • 2 tablespoons extra virgin olive oil
  • 2 tablespoons unsalted butter
  • 1 pound brown or white mushrooms, sliced
  • 1 large sweet yellow onion, sliced
  • 2 cloves garlic, minced

Seasonings

  • 1/2 teaspoon kosher salt
  • 1/2 teaspoon freshly ground black pepper
  • 1/2 teaspoon dried thyme

Instructions

  1. Heat the fat. Add the olive oil and butter to a large skillet set over medium-high heat and allow the butter to melt completely.
  2. Sauté the mushrooms. Add the sliced mushrooms to the pan, stirring them gently and cooking for 4 to 5 minutes without disturbing to allow them to brown nicely.
  3. Add aromatics and onions. Reduce heat to medium, then add the sliced onion, minced garlic, salt, pepper, and dried thyme to the skillet.
  4. Cook until tender. Continue cooking for 6 to 7 minutes, stirring occasionally until the mushrooms and onions are soft and have a lovely browned color.
  5. Adjust seasoning and serve. Taste and season with additional salt and pepper as desired, then serve warm as a side dish or garnish.

Notes

  • Use a combination of butter and olive oil to achieve both flavor and a higher smoke point.
  • Do not overcrowd the pan to ensure mushrooms brown properly instead of steaming.
  • Fresh thyme can be substituted for dried thyme if available, using about 1 1/2 teaspoons.
  • Try adding a splash of balsamic vinegar or soy sauce at the end for extra depth of flavor.
  • To keep it vegan, substitute butter with additional olive oil or a plant-based margarine.
