Gently clean the baby bella mushrooms using a damp paper towel. Trim the stems to ensure they're bite-sized.

Melt butter over medium heat, then add minced garlic and sauté until fragrant.

Add the mushrooms to the skillet and cook, stirring occasionally, until browned.

Pour Worcestershire sauce and soy sauce into the skillet and sprinkle in black pepper. Stir to coat.

Allow the mushrooms to simmer for a few minutes until the sauce thickens.

Remove from heat and top with chopped parsley before serving.
