Instructions

Step 1: Bring a large pot of salted water to a boil. Add 12 oz spaghetti and cook for 8-10 minutes until al dente, then drain and set aside.
Step 2: Heat 3 tbsp unsalted butter in a large skillet over medium heat. Add 4 minced garlic cloves and sauté for 30 seconds until fragrant — do not let it brown.
Step 3: Add 8 oz button mushrooms, cut into 1/4-inch slices, and cook for 5-7 minutes until golden and tender, stirring occasionally.
Step 4: Pour in 1/2 cup heavy cream, then stir in 1/4 cup grated Parmesan cheese. Cook for 3-4 minutes until the sauce thickens and coats the back of a spoon.
Step 5: Add 1 tsp fresh thyme, 1/2 tsp salt, and 1/4 tsp black pepper. Toss the cooked pasta into the skillet and mix until well coated.
Step 6: Serve immediately, garnished with additional Parmesan and thyme if desired.
