Clean the mushrooms with a damp paper towel and halve any large pieces.

Melt 2 tablespoons of butter in a large skillet over medium-high heat.

Add the mushrooms to the skillet in a single layer and sear without stirring for 3-4 minutes until browned.

Stir the mushrooms and continue to cook for another 3 minutes until tender.

Reduce heat to medium and add the remaining 2 tablespoons of butter and the minced garlic.

Sauté for 1 minute until the garlic is fragrant.

Stir in the Worcestershire sauce, salt, black pepper, red pepper flakes, and thyme.

Cook for an additional 2 minutes to glaze the mushrooms.

Remove from heat and garnish with fresh parsley before serving.
