Ingredients

• 2 tablespoons Unsalted butter
• 1 tablespoon Olive oil
• 1 large Yellow onion
• 2 cups Button mushrooms or cremini mushrooms, sliced
• 2 cloves Garlic cloves, minced
• 0.5 teaspoon Salt
• 0.25 teaspoon Black pepper
• 1 tablespoon Soy sauce
• 0.25 cup Beef stock or vegetable stock
• 1 teaspoon Fresh thyme leaves, chopped (optional)

Directions

Step 1

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

Step 2

Slice the onion thinly and add it to the skillet. Cook for 8-10 minutes, stirring occasionally, until the onions are golden and soft.

Step 3

Add the sliced mushrooms to the skillet with the onions. Stir well and cook for another 8-10 minutes, or until the mushrooms have released their moisture and start to brown.

Step 4

Stir in the minced garlic and cook for 1-2 minutes until fragrant, being careful not to burn the garlic.

Step 5

Season the mixture with salt and black pepper. Add the soy sauce and stir to coat the onions and mushrooms evenly.

Step 6

Pour in the beef stock or vegetable stock and allow it to simmer for 2-3 minutes, or until the liquid reduces slightly and creates a saucy consistency.

Step 7

If desired, sprinkle chopped fresh thyme over the mixture for an added layer of flavor. Stir well and cook for 1 more minute.

Step 8

Remove the skillet from heat and spoon the mushroom onion topping over cooked burgers or steaks. Serve immediately and enjoy!
