1-First Step: Bring a large pot of salted water to a boil. Start your pasta when you begin mushrooms so everything finishes around the same time.

2-Second Step: Cook pasta according to package instructions minus 1 minute. Reserve one mug of pasta cooking water, then drain pasta.

3-Third Step: Melt half of the butter and all the olive oil in a large skillet over medium heat.

4-Fourth Step: Add mushrooms and cook until water is released and evaporated, mushrooms start to turn golden around edges, about 5 minutes. Add salt and pepper halfway through.

5-Fifth Step: Add garlic and the remaining butter, then cook 2 more minutes until mushrooms and garlic are golden.

6-Sixth Step: Add pasta, about 3/4 cup reserved pasta water, and parmesan cheese. Toss gently until water reduces and thickens into a glossy sauce coating the pasta. Add more pasta water if pasta dries out.

7-Seventh Step: Adjust seasoning with salt and pepper if needed.

8-Final Step: Remove from heat and serve immediately topped with fresh parsley and more parmesan.
