Pasta and Broth
- 8 ounces Spaghetti
- 2 cups Vegetable Broth
Vegetables
- 8 ounces Cremini Mushrooms, sliced
- 2/3 cup Onion, diced
- 2 cloves Garlic, finely diced
Fats and Dairy
- 3 tablespoons Olive Oil, divided
- 1/2 cup Heavy Whipping Cream
- 1/2 cup Parmesan cheese (pecorino Romano works well too)
Seasonings and Garnishes
- Salt and Pepper to taste
- 1 tablespoon Lemon Juice
- Parmesan cheese for garnish
- Parsley leaves, chopped for garnish
- Red Chili Flakes (optional)
- Heat the Instant Pot: Set the Instant Pot to sauté mode and add 2 tablespoons of olive oil to heat.
- Sauté Mushrooms: Add the sliced mushrooms and cook for 4-5 minutes, stirring frequently until they release their moisture and turn golden brown. Remove mushrooms and set aside.
- Sauté Aromatics: Without cleaning the pot, add the remaining tablespoon of olive oil, then sauté diced onions and garlic for 2 minutes until fragrant. Turn off the sauté mode.
- Deglaze the Pot: Pour in the vegetable broth and scrape the bottom of the pot with a spatula to loosen any browned bits, preventing burning during pressure cooking.
- Add Pasta: Break spaghetti noodles in half and spread evenly in the pot, ensuring they are submerged in the broth.
- Pressure Cook: Close the lid, set the vent to sealing position, and pressure cook on high for 5 minutes—about 1 minute less than half the recommended stovetop pasta cooking time.
- Release Pressure: When cooking completes, perform a quick release to release steam manually.
- Add Cream and Cheese: Stir in the heavy cream and Parmesan cheese until fully melted and combined into a creamy sauce.
- Combine Mushrooms: Return the sautéed mushrooms to the pot and mix well with the pasta and sauce.
- Season and Finish: Adjust salt and pepper to taste, then stir in the lemon juice for brightness.
- Garnish and Serve: Top with additional Parmesan cheese, chopped parsley, and optional red chili flakes before serving.
Notes
- You can substitute cremini mushrooms with white button mushrooms or portobello for variation.
- Use pecorino Romano cheese instead of Parmesan for a sharper flavor.
- The lemon juice adds a fresh contrast to the creaminess—do not skip.
- Red chili flakes are optional if you prefer a little heat.
- If preferred, chicken broth can be used instead of vegetable broth for non-vegetarian versions.
- For a dairy-free version, substitute cream and cheese with plant-based alternatives.
