Ingredients:
- 1 lb cremini mushrooms, sliced 1/4 inch thick
- 2 tbsp extra virgin olive oil
- 2 tbsp unsalted butter
- 2 large shallots, finely minced
- 4 cloves garlic, minced
- 1 tsp fresh thyme leaves, chopped
- 12 oz fettuccine pasta
- 1 cup heavy cream
- 3/4 cup freshly grated Parmesan cheese
- 2 cups fresh baby spinach
- 1/2 cup reserved starchy pasta water
- 1/2 tsp sea salt
- 1/2 tsp freshly cracked black pepper
- 1/4 tsp ground nutmeg
Instructions:
- Bring a large pot of salted water to a boil and cook fettuccine according to package instructions until al dente. Reserve at least 1/2 cup of pasta water before draining.
- Heat olive oil and butter in a wide skillet over medium-high heat. Add mushrooms in a single layer and dry-sear without stirring for 4-5 minutes until mahogany brown. Stir and cook for 2 more minutes.
- Reduce heat to medium. Add the minced shallots, and thyme. Sauté for 2-3 minutes until shallots are translucent.
- Add the minced garlic and cook for 30-60 seconds until fragrant, being careful not to burn it.
- Pour in the heavy cream and bring to a gentle simmer for 3-4 minutes until the liquid reduces slightly and starts to thicken. Whisk in the Parmesan cheese until melted and smooth.
- Add the baby spinach and cooked pasta to the skillet. Toss vigorously, adding the reserved pasta water a tablespoon at a time until the sauce emulsifies and clings to the noodles.
- Season with sea salt, black pepper, and nutmeg. Serve immediately with extra Parmesan.
