Bring a large pot of salted water to a rolling boil. Add the fettuccine and cook according to package directions until al dente. Before draining, reserve 1/2 cup of the pasta water. Drain the pasta and set aside.

While the pasta cooks, melt the unsalted butter in a large skillet or Dutch oven over medium heat. Add the sliced cremini mushrooms and sauté for 5-7 minutes, stirring occasionally, until they are tender and have released their moisture.

Add the minced garlic to the skillet with the mushrooms and cook for 1 minute more, until fragrant. Be careful not to burn the garlic.

Pour in the heavy cream, freshly grated nutmeg, salt, and freshly ground black pepper. Bring the mixture to a gentle simmer, then reduce the heat to low and let it cook for 2-3 minutes, stirring occasionally, until it thickens slightly.

Remove the skillet from the heat. Gradually stir in the 1 1/2 cups of freshly grated Parmesan cheese until it is fully melted and the sauce is smooth and creamy. If the sauce is too thick, add a splash or two of the reserved pasta water until it reaches your desired consistency.

Add the drained fettuccine directly into the skillet with the Alfredo sauce. Toss gently to coat the pasta evenly with the creamy mushroom sauce. If needed, add a bit more reserved pasta water to achieve a silky texture.

Serve immediately, garnished with fresh chopped parsley and extra grated Parmesan cheese, if desired.
