I'm going to shoot straight with you, my husband and I almost got into a fight when I made this. He was supposed to photograph it and he looked at it and said, “You used a can of mushroom soup?” Does the man not know me??

OF COURSE NOT! This Mushroom Pasta recipe is the dish that will convince you that you never need to use a can of mushroom soup again.

This dish is so very creamy, cheesy, rich and absolutely crave-worthy. It's a simple mushroom pasta recipe, yet it's absolutely bursting with complex flavors!

And you know what else makes this recipe so very appealing? How ridiculously quick and easy it is. As you probably already know, I'm all about taking a delicious dish and making it as simple as possible without compromising on flavor. This dish absolutely delivers on all fronts. It's made in my trusty Instant Pot, and it's done in less than 30 minutes with minimal effort on my part. It's seriously everything I dream of in a pasta recipe: simple, quick, and crazy delicious.

Ingredients You'll Need

• Fettuccini- Although it's not customary, you will need to break the pasta noodles in half to be able to fit them in the Instant Pot and submerge them in water.
• Butter
• Minced Garlic
• Red Pepper Flakes- Adds just a touch of heat to help balance the fat content of the mascarpone cheese.
• Dried Thyme
• Ground Black Pepper
• Kosher Salt
• Portabella Mushrooms- These will be sliced into small bite-sized pieces
• Onions
• Mascarpone Cheese- Creates the decadent sauce that perfectly covers every noodle
• Shredded parmesan cheese
• Dried Thyme- This is an optional ingredient. If you don't have it in your spice rack, feel free to omit it.

How To Make Mushroom Pasta With Mascarpone Sauce

1. Saute. Turn the Instant Pot on Sauté. Once the pot is hot, add butter, garlic, red pepper flakes, thyme, and sauté for 30 seconds.
2. Add veggies. onions, mushrooms, salt, pepper, and water and stir.
3. Add pasta. Put in the pasta and push down into the water as much as possible.
4. Add cheese. Place the mascarpone cheese on top of the pasta. Do not stir otherwise your cheese could stick and burn.
5. Cook. Secure the lid on the pot. Close the pressure-release valve. Select PRESSURE COOK and set the pot at HIGH pressure for 6 minutes. Allow the pot to sit undisturbed for 5 minutes, then release any remaining pressure.
6. Stir. Open the lid and stir. Stir in the parmesan cheese and mix well, allowing the mixture to thicken.
7. Serve. Garnish with thyme and serve.

Tips And Tricks

• When I say don't stir after adding the mascarpone cheese to the Instant Pot, I really mean don't stir! That is unless you like the flavor of burnt cheese in your dishes.
• Serve with a simple salad and some crusty bread on the side to sop up all that delicious sauce.
• If you are having a hard time finding mascarpone cheese (or if you just don't feel like going to the grocery store), you can use cream cheese mixed with heavy whipping cream in its place. Simply mix 8 ounces of room temperature cream cheese with a 1/4 cup of heavy whipping cream and mix well. I do highly recommend picking up some mascarpone cheese though, as it gives the Mushroom Pasta a richer taste.

How Long Does It Last?

Pasta is always a great dish to double up on when you're cooking because it makes some of the best leftovers. The noodles continue to absorb the flavor the longer they are sitting in the sauce.

For the best bite, I would suggest enjoying this mushroom pasta within 4-5 days of preparing it.
