It is the sort of weeknight dinner that comes together in a single pan while the pasta cooks. Serve it as a main dish or as a simple side, and customize it with whatever herbs or vegetables you have on hand.

Why This Garlic Butter Mushroom Pasta Recipe Works
Mushrooms are the star, so they get proper treatment. A hot pan and a little space let the slices brown instead of steam, which builds a deep, meaty flavor that needs very little help.
Butter and olive oil work as a team. The oil raises the cooking temperature so the butter does not burn, and the butter brings richness and a toasty aroma to the sauce.
Tossing the hot pasta with Parmesan and the remaining butter creates a light, silky coating without any cream. A splash of pasta water makes the sauce glossy.
Ingredients for Garlic Butter Mushroom Pasta
- 12 ounces pasta, a mix of short and long shapes or all one shape
- 1 tablespoon kosher salt for the pasta water
- 14 ounces mushrooms, sliced 1/4 inch thick
- 3 tablespoons unsalted butter, divided
- 1 tablespoon olive oil
- 2 cloves garlic, finely minced
- 1/4 teaspoon kosher salt
- 1/2 teaspoon black pepper
- 1/2 cup freshly grated Parmesan, plus 2 tablespoons for serving
- 2 tablespoons finely chopped fresh parsley
- 1/2 cup reserved pasta cooking water
Pasta: A mix of orecchiette and spaghetti gives fun texture, but any single shape works. Cook it until al dente and drain, saving a little water.
Mushrooms: Cremini, white button, or a mix all work. Wipe them clean rather than soaking and slice them evenly so they cook at the same pace.
Butter and oil: Unsalted butter lets you control the salt. The olive oil helps the mushrooms brown without scorching the butter.
Garlic: Add garlic only after the mushrooms are golden. It burns quickly and turns bitter.
Parmesan and parsley: Freshly grated Parmesan melts smoothly. Parsley adds a bright, fresh finish.
How to Make Garlic Butter Mushroom Pasta
1. Cook the pasta. Boil the pasta in generously salted water until al dente. Reserve 1/2 cup of the cooking water, then drain.
2. Heat the pan. Warm the olive oil and 1 tablespoon of the butter in a large skillet over medium high heat until the butter foams.
3. Brown the mushrooms. Add the mushrooms in a single layer, working in two batches if needed. Cook for 5 to 7 minutes, stirring only now and then, until golden and tender.
4. Add the garlic. Stir in the garlic, salt, and pepper and cook for about 1 minute, until fragrant.
5. Toss. Add the hot pasta, the remaining 2 tablespoons butter, and the Parmesan. Stir until the butter melts, adding pasta water a splash at a time until glossy.
6. Serve. Top with parsley and extra Parmesan and serve right away.
How to Serve Garlic Butter Mushroom Pasta
Serve the pasta hot in shallow bowls with extra Parmesan. A simple Italian house salad and a side of air fryer asparagus round out the plate, while fluffy homemade dinner rolls soak up any buttery sauce. For something refreshing to sip, try a blueberry mojito pitcher on the side.
How to Store and Reheat Garlic Butter Mushroom Pasta
Refrigerate leftovers in an airtight container within 2 hours and use within 3 days. Reheat in a skillet over medium heat with a splash of water or broth until steaming hot, 165 degrees F. Freezing is not recommended because the mushrooms turn watery.
Tips and Variations for Garlic Butter Mushroom Pasta
Do not crowd the pan. Too many mushrooms at once will steam and turn gray. Cook in batches for better browning.
Leave them alone. Let the slices sit for a minute or two before stirring so they develop color.
Salt at the end. Adding salt late keeps the mushrooms from releasing too much water early.
Mix your mushrooms. A blend of cremini, shiitake, and oyster mushrooms adds depth.
Make it creamier. Stir in a splash of heavy cream or a spoonful of creme fraiche before serving.
Add herbs. Fresh thyme or basil goes well with mushrooms and butter.
Wipe, do not soak. Mushrooms absorb water, so clean them with a damp towel.
Store smart. Cooked pasta dishes should cool quickly. See the Texas AgriLife Extension food safety guide for basic handling tips.
Frequently Asked Questions About Garlic Butter Mushroom Pasta
Can I make garlic butter mushroom pasta without Parmesan?
Yes. Skip the cheese and add a little extra salt and a squeeze of lemon for brightness.
What kind of mushrooms work best in garlic butter mushroom pasta?
Cremini mushrooms are a reliable choice with deep flavor. White button mushrooms work too, and a mix of wild varieties adds extra depth.
How do I keep garlic butter mushroom pasta from getting dry?
Reserve pasta water and add it a splash at a time while tossing. The starch and butter create a glossy sauce that coats the noodles.
Can I add chicken or shrimp?
Yes. Cook the protein first, set it aside, and fold it back in at the end. Chicken should reach 165 degrees F and shrimp should turn pink and opaque.
Can I make this ahead?
It tastes best fresh, but you can slice the mushrooms and mince the garlic ahead of time. Cook the pasta and sauce right before serving.
