Step-by-Step Instructions
Step 1: Cook the Pasta
Boil Water: In a large pot, bring salted water to a boil.
Add Pasta: Once boiling, add the pasta and cook according to package instructions until al dente.
Reserve Pasta Water: Before draining, reserve about ½ cup of the pasta cooking water.
Drain: Drain the pasta in a colander and set aside.
Step 2: Prepare the Sauce
Sauté Aromatics: In a large skillet, heat olive oil and butter over medium heat. Add the chopped onion and sauté for 3-4 minutes until translucent.
Add Garlic and Mushrooms: Add the minced garlic and sliced mushrooms to the skillet. Cook for an additional 5-6 minutes, stirring occasionally, until the mushrooms are soft and browned.
Make the Cream Sauce: Pour in the heavy cream and bring to a gentle simmer. Let it cook for about 2 minutes, allowing it to thicken slightly.
Incorporate Cheese: Stir in the grated Parmesan cheese until melted and well combined. Season with salt and pepper to taste.
Step 3: Combine Pasta and Sauce
Add Pasta to Sauce: Add the drained pasta to the skillet and toss to coat evenly in the creamy mushroom sauce. If the sauce is too thick, add a bit of the reserved pasta water until you reach the desired consistency.
Taste and Adjust: Taste the pasta and adjust the seasoning with more salt and pepper if needed.
Step 4: Serve
Garnish and Serve: Serve the pasta hot, garnished with freshly chopped parsley and extra Parmesan cheese if desired.
