Garlic butter mushroom pasta is a simple dish that anyone can make. It is as flavorful as a weekend meal but is perfect for weeknights because it only takes 20 minutes to prepare.

Serve this delicious pasta with a big green salad and your whole family will wonder if you spent hours in the kitchen.

Rich Mushroom Flavor

Mushrooms are a food that people either love or hate—but my family absolutely loves them. One of the best aspects of mushrooms is that they lend layers of flavor without a lot of effort, which makes them perfect for pasta dishes that aren’t complicated by a lot of ingredients.

Cooking Notes

This mushroom pasta recipe only takes around 20 minutes to make, and you can save a lot of time by buying pre-sliced mushrooms.

  • Start by cooking the pasta according to package instructions or making your own homemade pasta using my easy-to-follow recipe. I typically use spaghetti because I always have a box in the pantry. When my sister used this recipe she used bow tie pasta, but I imagine it would also be amazing with linguine or fettuccine noodles.
  • In a large skillet, sauté your mushrooms in about four tablespoons of butter. I prefer to use unsalted butter because I can always add more salt, but I can’t take it away once it’s in the dish. You can use any mushrooms that you find on sale or prefer. I typically try to find white mushrooms or baby portabella mushrooms because they are something my family is familiar with, even the little ones. Baby portabellas also have a much stronger flavor and make a more savory dish.
  • Four tablespoons may seem like a lot of butter, but remember this butter is going to be used to coat the pasta. It’s in the pot now to capture the flavor of the mushrooms.
  • After you have browned your mushrooms and they are nice and soft, add in your garlic. Salt and pepper to taste. Garlic only needs about one minute to become fragrant, and we don’t want it to burn as the mushrooms cook. Allow your sauce to sit to the side and allow the flavors to mix well while you cook your pasta.
  • After your pasta is cooked, reserve a quarter cup of the pasta water and add it to your sauce skillet. Drain the pasta as you usually would. Add your pasta to the sauce and toss with tongs or two forks to combine.
  • Portion out your pasta and grate some fresh Parmesan cheese on top.

4 servings


  • 8 ounces pasta
  • 12 ounces sliced mushrooms
  • 4 tablespoons unsalted butter, divided
  • 3 cloves garlic, minced
  • 1/2 teaspoon salt
  • 1/4 teaspoon pepper
  • 1/2 cup Parmesan cheese, grated or shredded
  • parsley, for serving


  1. Cook your pasta according to package directions in a large pot of salted boiling water. When your pasta is finished cooking, reserve ¼ cup of the pasta water and drain the rest.
  2. While your pasta is cooking, melt 2 tablespoons of the butter over medium-high heat in a large skillet. Meanwhile, slice the mushrooms. Add your sliced mushrooms to the hot skillet and cook for between 4 and 5 minutes, or until they start turning golden brown.
  3. Add the minced garlic to the skillet. Salt and pepper to taste. Cook for 1 more minute, stirring constantly so your garlic can become fragrant.
  4. Turn the heat to low and add in the remaining 2 tablespoons of butter. Allow the butter to melt and add in your pasta, the reserved pasta water, and parmesan cheese. Toss the pasta in the sauce using tongs or two forks.
  5. Taste your pasta and adjust the seasonings. Top with additional Parmesan cheese if desired and serve immediately.
