Making One Pot Pasta with Spinach & Mushrooms is a breeze if you follow these steps:

1. Sauté the Onions and Garlic: In a large pot, heat olive oil over medium heat. Add the diced onion and sauté until translucent, about 3-4 minutes. Stir in the minced garlic and cook for an additional 1 minute until fragrant.

2. Add the Mushrooms: Add the sliced mushrooms to the pot and cook for about 5-7 minutes, or until they are tender and have released their moisture.

3. Combine the Pasta and Broth: Pour in the vegetable broth and bring to a boil. Once boiling, add the pasta, Italian seasoning, salt, and pepper. Stir well to ensure the pasta is submerged in the broth.

4. Cook the Pasta: Reduce the heat to a simmer and cover the pot. Cook according to the pasta package instructions, usually about 10-12 minutes, stirring occasionally.

5. Add the Spinach: When the pasta is just about done, stir in the fresh spinach leaves. Cook for an additional 2-3 minutes until the spinach wilts.

6. Incorporate Heavy Cream: If you prefer a creamy sauce, stir in the heavy cream at this stage. Allow it to heat through for another minute.

7. Serve: Once the pasta is cooked and the sauce has thickened slightly, remove the pot from heat. Taste and adjust seasoning if necessary.

8. Garnish: Serve the pasta hot, topped with grated Parmesan cheese and fresh basil leaves for a burst of flavor.
