• For a vegan version, substitute cream with coconut milk and use a plant-based Parmesan alternative.
• Add cooked chicken or sausage for extra protein.
• Try different mushroom varieties like shiitake or button mushrooms for variety in texture and flavor.

FAQs

Can I use a different type of pasta?

Yes, you can substitute spaghetti with other long pasta like fettuccine or linguine. Adjust the cooking time slightly based on package instructions, keeping the pressure cooking rule of one minute less than half the stovetop time.

Do I have to use an Instant Pot for this recipe?

No, but cooking in an Instant Pot speeds up the process and infuses flavors well. If using a stovetop, sauté the mushrooms and aromatics separately, cook pasta in broth, then combine with cream and cheese off the heat.
