Creating Creamy Mushroom and Spinach Pasta is simple if you follow these straightforward steps:

1. Cook the Pasta: Boil salted water in a large pot. Add the fettuccine and cook according to package instructions until al dente. Drain and set aside, reserving about ½ cup of the pasta water.

2. Sauté the Onions: In a large skillet over medium heat, heat olive oil. Add the diced onion and sauté for about 3-4 minutes, until translucent.

3. Add Garlic and Mushrooms: Stir in the minced garlic and sliced mushrooms. Cook for about 5-7 minutes, or until the mushrooms are tender and browned.

4. Add Spinach: Toss in the fresh spinach and cook until wilted, about 2-3 minutes.

5. Make the Cream Sauce: Lower the heat and pour in the heavy cream. Mix well, bringing it to a gentle simmer. Stir in the grated Parmesan cheese until smooth. Season with salt and pepper to taste.

6. Combine with Pasta: Add the drained pasta to the skillet, tossing to coat in the sauce. If it’s too thick, add some reserved pasta water a little at a time until the desired creaminess is reached.

7. Serve: Plate the pasta, garnishing with additional Parmesan cheese and fresh parsley if desired.

8. Enjoy: Serve immediately and enjoy your delectable Creamy Mushroom and Spinach Pasta!
