This vegetarian-friendly mushroom pappardelle pasta is cozy, delicious, and lightly creamy! It's quick and easy, so dinner's on the table in just under 30 minutes.
Cook the pasta: Bring a large pot of salted water to a boil. Add 8 ounces dried pappardelle pasta, and cook until just before al dente (follow package instructions). Drain and save 1 cup of pasta cooking water for later.
Meanwhile, prepare the mushrooms. Remove any hard, woody stems and tear or slice them into bite-sized pieces.
Cook the mushrooms: Set a large skillet over medium-high heat with2 tablespoons neutral oil. Once the oil is shimmering, add 10 ounces oyster mushrooms in an even layer (cook in batches if needed). Cook for 2 - 3 minutes on each side until nicely golden-brown. Using tongs, flip and cook the mushrooms for an additional 2 - 3 minutes until golden-brown on the other side. Turn the heat off, then remove mushrooms from the pan and transfer to a plate. Season generously with salt and pepper and set aside. Note: Resist the urge to touch the mushrooms before the 2 minute mark here! They need to stay put to get a nice sear.
Cook the aromatics: With the heat still off, add 2 tablespoons unsalted butter. Once melted, add the minced 3 cloves garlic and 1 large shallot, and saute over medium-low heat for 1 - 2 minutes until aromatic.
Simmer the sauce: Stir in¾ cup heavy cream1 teaspoon Dijon mustard, lemon zest, and the seared mushrooms. Season with salt and black pepper, and simmer over low heat for 2 - 3 minutes until slightly thickened.
Add the pasta: Stir in the pasta, and toss to combine with tongs. If needed, stir in a bit of the reserved cooking water to loosen the sauce until it clings nicely to the pasta.If the sauce feels too loose, simmer it over medium-low heat to thicken it slightly as you continue to toss the pasta.
Finish the dish: Remove the pan from the heat, and stir in ¼ cup finely grated parmigiano-reggiano cheese, the juice from ½ a lemon, and ¼ cup flat-leaf parsley. Season again to taste, with salt and black pepper.
Divide amongst serving bowls and top with more cheese and parsley if desired.
Notes
Fresh Mushrooms: You can use any kind of mushrooms you like, but I recommend against white button mushrooms, as they won't have enough flavor! I love a mix of oyster mushrooms, wild varieties like maitake or chanterelles, and cremini mushrooms. For even more shroomy flavor, try adding in a pinch of ground porcini powder.
Pappardelle: I prefer pappardelle because it has a wide shape and soft, slightly chewy texture. You can use a high-quality dried pasta or a fresh egg pasta.
Heavy Cream: Heavy cream adds a bit of richness to the dish, but don't worry, it won't feel heavy! Do not use half-and-half or milk, as it won't be thick enough and may curdle with the lemon juice.
