Why This Recipe is Awesome

Equipment needed: Large deep skillet or Dutch oven, wooden spoon, measuring cups, knife

One Pot Creamy Mushroom Pasta
Ingredients
- 8 oz 225g fettuccine or linguine (can use any pasta shape)
- 2 Tbsp olive oil
- 1 Tbsp butter
- 1 small onion finely diced
- 3-4 cloves garlic minced
- 1 lb 450g mixed mushrooms (cremini, button, or shiitake), sliced
- 1 tsp dried thyme or 1 Tbsp fresh
- ½ tsp dried rosemary or 1 tsp fresh, chopped
- ¼ tsp red pepper flakes optional
- 3 cups vegetable or chicken broth
- ½ cup heavy cream or half-and-half for a lighter version
- ½ cup freshly grated Parmesan cheese plus extra for serving
- Salt and freshly ground black pepper to taste
- 2 Tbsp fresh parsley chopped (for garnish)
Instructions
- Heat the oil and butter in a large, deep skillet or Dutch oven over medium heat until the butter melts and starts to foam.
- Add the diced onion and cook for 3-4 minutes until translucent, stirring occasionally to prevent browning.
- Stir in the garlic and cook for just 30 seconds until fragrant, being careful not to let it burn.
- Add the mushrooms, thyme, rosemary, and red pepper flakes (if using). Cook for 5-7 minutes until the mushrooms release their moisture and begin to brown, stirring occasionally.
- Season with salt and pepper to taste, remembering the broth and cheese will add saltiness later.
- Pour in the broth and bring to a simmer, scraping any browned bits from the bottom of the pan (these add flavor!).
- Add the uncooked pasta to the pot, making sure it’s mostly submerged in the liquid. Reduce heat to medium-low and cook, stirring occasionally, for about 10-12 minutes or until the pasta is al dente and most of the liquid is absorbed.
- Stir in the heavy cream and Parmesan cheese until fully incorporated and the sauce coats the pasta evenly.
- Remove from heat and let the pasta sit for 2 minutes to allow the sauce to thicken slightly.
- Taste and adjust seasoning if needed, then serve immediately topped with additional Parmesan and fresh parsley.
Notes
- For deeper mushroom flavor, use a mix of varieties – cremini provide earthiness, while shiitake add a more intense umami quality.
- The pasta will continue to absorb liquid as it sits, so the dish is best served immediately after cooking.
- If the sauce becomes too thick, add a splash of broth or hot water to reach your desired consistency.
- For meal prep, you can sauté the mushrooms and onions in advance, then complete the recipe when ready to serve.
- This dish doesn’t reheat perfectly but is still delicious the next day – just add a splash of cream when reheating to revive the sauce.

Common Mistakes to Avoid
- Crowding the mushrooms in the pan – this causes them to steam rather than brown. If necessary, cook them in batches to ensure proper caramelization and flavor development.
- Using cold dairy products straight from the refrigerator – this can cause the sauce to separate. Let your cream come to room temperature before adding it.
- Overcooking the pasta – since it continues cooking in the residual heat, aim for slightly firmer than al dente when you add the cream.
- Not stirring enough during cooking – pasta can stick to the bottom of the pot, especially as the liquid reduces.
- Adding pre-grated cheese – these often contain anti-caking agents that prevent proper melting. Always grate your Parmesan fresh for the creamiest sauce.
Alternatives & Substitutions
- For dairy-free version: Replace butter with additional olive oil, use coconut cream instead of heavy cream, and nutritional yeast instead of Parmesan.
- For gluten-free diets: Substitute regular pasta with your favorite gluten-free pasta, but watch cooking times as they often cook faster.
- Protein additions: Add grilled chicken, sautéed shrimp, or crispy bacon for a non-vegetarian version.
- Vegetable variations: Add baby spinach, peas, or asparagus in the final minutes of cooking for extra color and nutrition.
- Herb options: Fresh tarragon or sage work beautifully with mushrooms if you want to change up the flavor profile.
FAQs
Can I use any type of pasta for this recipe?
Yes, though medium-length pasta like fettuccine, linguine, or penne works best. Very small pasta like orzo may cook too quickly, while very large shapes might not cook evenly. Adjust cooking time according to the package instructions.
Why did my sauce turn out watery?
This typically happens if you don’t let the pasta release enough starch or if you added too much liquid. Make sure your simmer is gentle but consistent, and if needed, let the finished pasta stand uncovered for a few minutes to thicken naturally.
Can I make this ahead of time for a dinner party?
This dish is best made fresh, but you can prep all ingredients in advance. For serving guests, cook it just before eating and keep it slightly saucier than you normally would, as it will continue to thicken as it sits.
What’s the best type of mushroom to use?
A mix provides the best flavor, but cremini (baby portobello) mushrooms offer the most bang for your buck with rich flavor and wide availability. Wild mushrooms like chanterelles or oyster mushrooms make an amazing splurge if available.
Is there a lower-calorie version of this dish?
Absolutely! Use half-and-half instead of heavy cream, reduce the Parmesan to ¼ cup, and increase the proportion of mushrooms to pasta. You’ll still get creaminess from the pasta starch while cutting fat and calories.
