Ingredients (Serves 4-6)

For the Pasta and Vegetables:

12 ounces (340g) fettuccine pasta (or linguine/tagliatelle for similar texture)
2 tablespoons olive oil
2 tablespoons unsalted butter
16 ounces (450g) mixed mushrooms (cremini, button, shiitake, or portobello), sliced
4 cloves garlic, minced
5-6 cups fresh baby spinach (about 150-200g), roughly chopped if large
Salt and freshly ground black pepper, to taste
Optional: Pinch of red pepper flakes for a subtle kick

For the Creamy Alfredo Sauce:

1 cup heavy cream (or half-and-half for a lighter version)
1 cup freshly grated Parmesan cheese (plus more for serving)
½ cup reserved pasta cooking water (essential for thinning the sauce)
2 tablespoons unsalted butter
Freshly grated nutmeg (a pinch, optional but recommended for authentic flavor)
Fresh parsley or basil, chopped, for garnish

Optional Add-Ins for Extra Flavor:

¼ cup dry white wine (like Pinot Grigio) for deglazing
1 small onion or shallot, finely diced
Lemon zest or juice for brightness

Using fresh, high-quality ingredients makes all the difference. Opt for real Parmesan (Parmigiano-Reggiano) grated at home—it melts better and tastes superior to pre-shredded varieties.

Step-by-Step Instructions

Follow these detailed steps for perfect results every time.

Prepare the Ingredients: Start by bringing a large pot of salted water to a boil for the pasta. While waiting, slice the mushrooms evenly for uniform cooking, mince the garlic, and wash the spinach. Grate the Parmesan cheese fresh— this is key for a smooth sauce.
Cook the Pasta: Add the fettuccine to the boiling water and cook according to package instructions until al dente (usually 8-10 minutes for dried pasta). Reserve at least 1 cup of pasta water before draining. This starchy liquid is crucial for adjusting the sauce consistency later.
Sauté the Mushrooms: In a large skillet or Dutch oven over medium-high heat, melt 2 tablespoons butter with the olive oil. Add the sliced mushrooms in a single layer (work in batches if needed to avoid crowding). Cook undisturbed for 3-4 minutes until golden on one side, then stir and continue cooking for another 4-5 minutes until browned and tender. Season with salt and pepper. Browning the mushrooms deeply enhances their umami flavor—don’t rush this step!
Add Aromatics and Spinach: Reduce heat to medium. Add minced garlic (and onion/shallot if using) and cook for 1-2 minutes until fragrant, being careful not to burn it. If using wine, pour it in now and scrape up any browned bits from the pan—let it reduce by half. Stir in the spinach in handfuls, allowing it to wilt down (about 2-3 minutes). The spinach will reduce significantly in volume.
Make the Creamy Sauce: Pour in the heavy cream and bring to a gentle simmer. Add the remaining 2 tablespoons butter and grated Parmesan. Stir constantly until the cheese melts and the sauce thickens slightly (about 3-5 minutes). Season with black pepper, a pinch of nutmeg, and salt to taste. If the sauce is too thick, add reserved pasta water a splash at a time until silky.
Combine Everything: Add the drained fettuccine directly to the skillet. Toss gently with tongs to coat every strand in sauce. If needed, add more pasta water for a glossy finish. Let it sit off the heat for 1-2 minutes to allow the sauce to adhere.
Serve Immediately: Divide into bowls, top with extra Parmesan, fresh herbs, and black pepper. Pair with crusty bread and a simple green salad.

Pro Tip: For extra creaminess, finish with a pat of butter or a drizzle of truffle oil.

Detailed Cooking Tips and Techniques

To achieve restaurant-quality results:

Mushroom Selection and Prep: Use a mix of mushrooms for complex flavor—cremini for meatiness, shiitake for earthiness. Clean with a damp paper towel; never soak as they absorb water.
Perfect Sauce Consistency: The sauce should coat the back of a spoon. Pasta water helps emulsify it, creating that signature gloss.
Avoid Curdling: Add cream off high heat and stir Parmesan gradually.
Al Dente Pasta: Slightly undercook as it finishes in the sauce.
Seasoning Layers: Salt the pasta water generously (it should taste like seawater), season mushrooms early, and adjust sauce at the end.

Common Mistakes to Avoid:

Overcooking spinach—it turns mushy.
Crowding the pan—mushrooms steam instead of brown.
Using low-quality cheese—it won’t melt smoothly.

Variations and Customizations

This recipe is incredibly adaptable:

Protein Additions: Stir in grilled chicken, shrimp, bacon, or Italian sausage for a heartier meal.
Vegan Version: Use cashew cream or coconut milk, vegan butter, nutritional yeast instead of Parmesan, and egg-free pasta.
Lighter Option: Substitute half the cream with milk or broth, or use Greek yogurt.
Extra Veggies: Add sun-dried tomatoes, peas, asparagus, or broccoli.
Spicy Twist: Incorporate chili flakes or hot sauce.
One-Pot Method: Cook everything in one skillet for easier cleanup—sauté veggies, add uncooked pasta with broth/cream, and simmer.

For gluten-free: Use GF fettuccine.
