Quick Facts
Yield: Serves 4
Prep Time: 10 minutes
Cook Time: 20 minutes
Total Time: 30 minutes
Ingredients
For the Main Dish:
12 oz fettuccine or linguine pasta
2 tbsp olive oil
8 oz cremini or white mushrooms, sliced
3 cups fresh spinach leaves
3 cloves garlic, minced
1/2 tsp salt, divided
1/4 tsp freshly ground black pepper
For the Sauce:
2 tbsp unsalted butter
2 cups heavy cream
1 cup freshly grated Parmesan cheese
1/4 tsp nutmeg (optional, but so good!)
How I Make It
Step 1:
Bring a large pot of salted water to a boil and cook your pasta until just tender (al dente), usually about 9-10 minutes. While it cooks, drain but save around 1 cup of that starchy pasta water—that’s a magic ingredient for your sauce.
Step 2:
Heat olive oil in a large skillet over medium-high heat. Add the sliced mushrooms with a pinch of salt and sauté until they’re golden and their moisture evaporates—about 6-7 minutes. You’ll notice their edges crisping up and that earthy aroma filling the kitchen, which is always a good sign!
Step 3:
Lower the heat to medium and stir in the minced garlic. Cook just until fragrant, around 30 seconds (watch carefully—garlic burns fast!). Add the spinach and toss until it wilts, which happens in about 1-2 minutes. Season with a bit more salt and black pepper.
Step 4:
In a separate saucepan, melt the butter over medium heat. Pour in the heavy cream and bring to a gentle simmer, stirring often. Add the nutmeg if using—it gives the Alfredo a subtle warmth that’s so comforting.
Step 5:
Gradually whisk in the Parmesan cheese until melted and the sauce thickens, about 3-4 minutes. If it feels too thick, add reserved pasta water a little at a time to reach your perfect creamy consistency.
Step 6:
Toss the cooked pasta into the skillet with mushrooms and spinach, then pour the Alfredo sauce over everything. Mix well to coat every strand, adding more pasta water if you want it saucier. Serve hot—with a sprinkle of extra Parmesan, of course!
Variations & Tips
Swap cremini mushrooms for shiitake or portobello for deeper flavor.
Add cooked grilled chicken or shrimp for some protein boost.
Use half-and-half instead of heavy cream for a lighter sauce (just expect it to be a bit thinner).
Don’t skip reserving pasta water—it helps your sauce cling perfectly to the noodles.
Add a squeeze of fresh lemon juice for a bright zing right before serving.
For a dairy-free twist, use cashew cream and nutritional yeast instead of butter, cream, and cheese.
How I Like to Serve It
This pasta is perfect on chilly evenings when you want something warming but fresh—the spinach adds just the right pop of color and nutrients. I love pairing it with a simple side salad or some garlic bread for dinner parties or busy weeknights. It also makes a great leftover lunch—you can gently reheat it in a skillet with a splash of milk to keep the sauce creamy.
Notes
Store leftovers in an airtight container in the fridge for up to 3 days. Reheat gently on the stove with a splash of cream or milk.
To save time, you can prep the mushrooms and spinach ahead of time and refrigerate before cooking.
Closing: This Mushroom Spinach Alfredo Pasta always wins in my kitchen because it’s creamy, comforting, and surprisingly simple—just what every home cook needs on a busy night.
