Linguine with Creamy Mushroom Sauce

Bring a large pot of water to a boil over high heat. Cook pasta according to package directions. Reserve 1/2 cup of the pasta water, then drain the pasta.

Meanwhile, heat oil and garlic in a large skillet over medium heat until fragrant, about 2 minutes. Add mushrooms, shallots and thyme and increase heat to high. Cook, stirring occasionally, until the liquid the mushrooms release has evaporated and the mushrooms are starting to brown, 11 to 13 minutes.

Add wine to the pan and cook until it is reduced by about half, about 3 minutes. Stir in the reserved pasta water, sour cream (or crème fraîche), Parmesan, butter, salt and pepper. Add the pasta and toss to coat. Serve topped with more Parmesan and parsley, if desired.
