Linguine with Creamy Mushroom Sauce is the best date-night in or weeknight vegetarian pasta recipe. Easy and absolutely delicious creamy mushroom pasta sauce with chunky mushrooms, garlic and Parmesan cheese. Yum!
Prepare the mushrooms: Trim the stems off the mushrooms. Tear the caps into generous bite-sized pieces - you want a nice chunky texture.
Bring a large (5-6 quarts) water to a boil along with 4 tablespoons kosher salt (use half the amount of regular table salt). Cook the pasta according to package directions, until al dente. Before draining the pasta, scoop out 1 cup of the cooking water and reserve.
While the pasta cooks, heat the oil in a large (12-inch) skillet (preferably nonstick) over medium-high heat. Add the mushrooms to the pan and spread them out in one layer. Cook 5 minutes without stirring. Give the pan a shake and stir the mushrooms around. Cook another 5 minutes.
At this point, the mushrooms should be taking on some color and releasing some liquid. Add 1 teaspoon salt, shallots, garlic, thyme and chili and stir well. Cook until the shallots are softened, about 2 minutes.
Add the lemon juice, creme fraiche and parsley to the mushrooms. Simmer until the sauce thickens. Add 1/3 cup of the reserved water and stir, scraping the pan to release any browned bits.
Put the cooked pasta in the pan and use tongs to toss in the sauce. Add a bit more pasta water if the sauce seems dry. Remove from the heat, sprinkle with the Parmesan and serve.
