Ingredients

• 2 tablespoons unsalted butter
• 1 tablespoon olive oil
• 1 large yellow onion
• 8 ounces cremini or white mushrooms
• 2 cloves garlic
• 1 teaspoon fresh thyme leaves
• 1 teaspoon low-sodium soy sauce
• 0.5 teaspoon salt
• 0.25 teaspoon black pepper

Directions

Step 1

Peel the onion and slice it into thin rings, about 1/4-inch thick.

Step 2

Clean the mushrooms with a damp paper towel to remove any dirt, then slice them into 1/4-inch thick pieces.

Step 3

Mince the garlic cloves and set them aside for later use.

Step 4

Heat a large skillet over medium heat and add the butter and olive oil. Allow the butter to melt completely and start to bubble slightly.

Step 5

Add the sliced onions to the skillet and sauté for about 5 minutes, stirring occasionally, until they begin to soften.

Step 6

Add the sliced mushrooms and continue to cook for another 8-10 minutes, stirring often, until the mushrooms release their moisture and begin to brown.

Step 7

Stir in the minced garlic and thyme leaves, cooking for 1-2 minutes until fragrant.

Step 8

Add the soy sauce, salt, and black pepper, and mix well to coat the mushrooms and onions evenly.

Step 9

Lower the heat slightly and cook for an additional 3-4 minutes to allow the flavors to meld together.

Step 10

Taste and adjust seasoning as needed before serving the mushroom and onion mixture over steak.
