Instructions

  1. Step 1: Melt 3 tbsp unsalted butter in a large skillet over medium heat until foaming. Add 4 minced garlic cloves and sauté for 30 seconds until fragrant, being careful not to brown the garlic.
  2. Step 2: Add 16 oz sliced white button mushrooms to the skillet. Cook for 8-10 minutes, stirring occasionally, until mushrooms release their juices and become tender and golden around the edges.
  3. Step 3: Stir in 1 tbsp fresh thyme leaves, 1/2 tsp salt, and 1/4 tsp black pepper. Continue cooking for 2 more minutes until the thyme is fragrant.
  4. Step 4: Remove from heat and sprinkle 1/4 cup grated Parmesan cheese over the mushrooms. Toss gently to combine and garnish with 2 tbsp chopped fresh parsley before serving warm.
