Creating Mushroom Garlic Spaghetti is a simple process. Follow these steps to achieve the perfect dish:

1. Cook the Spaghetti: Bring a large pot of salted water to a boil. Add the spaghetti and cook according to package instructions until al dente. Drain and set aside, reserving a little pasta water.

2. Heat the Olive Oil: In a large skillet, heat the olive oil over medium heat.

3. Sauté the Garlic: Add the minced garlic to the skillet. Sauté for about 1-2 minutes until fragrant, but be careful not to burn it.

4. Add the Mushrooms: Stir in the sliced mushrooms. Cook for about 5-7 minutes until they are tender and browned.

5. Season: If desired, add red pepper flakes for a little heat. Season with salt and pepper to taste.

6. Combine with Pasta: Add the cooked spaghetti to the skillet with the mushrooms. Toss to combine, adding reserved pasta water as needed to create a light sauce.

7. Finish with Cheese: If using, sprinkle grated Parmesan cheese over the spaghetti and toss until well combined.

8. Garnish: Remove from heat and garnish with chopped fresh parsley before serving.
