Mushroom and Garlic Spaghetti Dinner

A fast and easy recipe for spaghetti tossed in a sautéed mushroom, garlic, and butter sauce.

INGREDIENTS

• 1 pound dried spaghetti
• 3 tablespoons unsalted butter, divided
• 1 tablespoon olive oil
• 1 pound cremini mushrooms, sliced
• Kosher salt
• Freshly ground black pepper
• 6 cloves garlic, minced
• 1/4 teaspoon red pepper flakes (optional)
• 1/2 cup grated Pecorino Romano cheese, plus more for serving
• 2 tablespoons coarsely chopped fresh parsley leaves

INSTRUCTIONS

1. Bring a large pot of salted water to a boil. Add the pasta and cook until al dente, 7 to 9 minutes or according to package instructions. Meanwhile, cook the mushrooms.
2. Heat 1 tablespoon of the butter and the oil in a large skillet over medium heat until shimmering. Add the mushrooms, season with salt and pepper, and sauté until browned and tender, about 5 minutes. Add the garlic, red pepper flakes if using, and remaining 2 tablespoons butter and sauté for 1 minute more.
3. When the pasta is ready, reserve 3/4 cup of the cooking water, then drain the pasta. Add the pasta, reserved cooking water, and cheese to the skillet. Toss over medium heat until the cheese is melted and the sauce thickens and coats the pasta, about 2 minutes. Add the parsley and toss to combine. Serve in shallow bowls with more cheese for serving.
