Creamy One-Pot Mushroom Pasta Recipe for Weeknight Dinners

Umami-packed comfort in one pot: this One Pot Creamy Mushroom Pasta is a rich, easy vegetarian dish that tastes restaurant-worthy and comes together quickly — perfect for busy weeknights.

What are the ingredients in this One Pot Creamy Mushroom Pasta?

This vegetarian one-pot pasta uses familiar ingredients and offers simple swaps. Below is what I used and notes on each item:

• Butter – Sauteeing mushrooms in butter adds depth of flavor; olive oil is used later when cooking the onion.
• Mushrooms – Cremini are my pick for flavor and color, but white button or sliced portobello work well. A mix of types is great too.
• Olive oil – Used when cooking the onions to add flavor and prevent sticking.
• Onion – Thinly sliced and cooked until soft and golden to build flavor.
• Garlic cloves – Adds essential aroma and savory balance; use to taste.
• White wine – Deglazes the pot and brings brightness; can be replaced with broth if you prefer, though flavor will be slightly different.
• Vegetable broth – A quality broth is the sauce base.
• Water – Add a small amount if the liquid level is too low to cook the pasta evenly.
• Short pasta – Campanelle, rigatoni, or other short shapes with grooves hold the sauce well.
• Heavy cream – Makes the sauce rich and silky. A dairy-free creamer like plain Nutpods can substitute for a lighter option.
• Parmesan – Freshly grated is best; stir in gradually so it melts evenly into the sauce.
• Salt & pepper – Season to taste after finishing the pasta.
• Parsley – Optional, for freshness and presentation.

Equipment you’ll need to make this pasta:

Use a heavy-bottomed pot with a lid so the pasta cooks evenly. A Dutch oven or large lidded saucepan works best. You’ll also want a sharp knife and cutting board plus a wooden spoon for deglazing and stirring.

How to make this One Pot Creamy Mushroom Pasta:

Choose a heavy-bottomed pot with a lid. Everything cooks in the same pot from start to finish.

1) Cook the mushrooms: Melt 2 tablespoons unsalted butter over medium-high heat. When it froths, add 12 ounces thickly sliced mushrooms and cook 6–8 minutes until they begin to brown. Stir minimally so they can color.

2) Cook the onions: Add 1 tablespoon olive oil, 1 large thinly sliced onion and a generous pinch of salt. Cook 8–10 minutes, stirring occasionally, until the onions are soft and slightly golden. Add 3 minced garlic cloves and cook 1 minute until aromatic.

3) Deglaze: Pour in 1/2 cup white wine a splash at a time and scrape up browned bits with a wooden spoon as the alcohol cooks off, about 2–3 minutes. The onions will become jammy.

4) Add broth and pasta: Stir in 4 cups low-sodium vegetable broth and 1 pound short pasta. The liquid should nearly reach the top of the pasta; if it’s far below, add up to 1/2 cup room-temperature water. Bring to a boil, reduce to medium-low, cover, and simmer 15–20 minutes, stirring every 5 minutes. Add extra liquid if it looks dry.

5) Finish the sauce: When pasta is al dente and most liquid is absorbed, stir in 1/2 cup heavy cream and 1/4 cup freshly grated Parmesan. Season with fresh ground black pepper and salt to taste. If the sauce seems thick, add a splash of water or broth. The sauce will thicken as it cools.

6) Serve: Stir in chopped parsley just before serving and top with extra Parmesan if desired. Leftovers keep well in the refrigerator for up to 5 days.

Best tips for making one pot pasta:

• Trust the process. One-pot pastas release moisture during cooking; give it time to reduce and thicken.
• Adjust as you go. Different pots, stoves, and liquid temperatures change cook time slightly — use the ranges and watch the pot.
• Lid on vs off. Lid on traps steam and cooks faster; lid off lets moisture escape. Use whichever helps the pasta finish correctly.

What to serve with this One Pot Creamy Mushroom Pasta?

This works as a satisfying vegetarian main. You can also add diced cooked chicken for extra protein. Serving suggestions:

• Sourdough or garlic bread for dipping.
• Serve alongside grilled steak, salmon, roasted chicken, a green salad, or roasted vegetables.
• Pair with a tray of roasted vegetables for a full meal.

Ways to customize this pasta recipe:

• Stir in a handful of chopped spinach near the end of cooking.
• Add frozen peas for an easy vegetable boost.
• Use chicken broth and add cooked chicken for a meatier version.
• Include red chili flakes for heat.

Is this recipe freezer friendly?

No — I don’t recommend freezing this dish; the cream and pasta texture don’t hold up well after freezing and thawing.

How to store One Pot Creamy Mushroom Pasta:

Store leftovers in an airtight container in the refrigerator for up to 5 days.

How to reheat One Pot Creamy Mushroom Pasta:

Reheat on the stovetop: add about 1/4 cup water or broth to a small pot, warm over medium, and stir frequently until the pasta is silky and heated through. Add more liquid if it looks dry while heating.
