Calling all carb lovers! This one’s for you. I absolutely love pasta in any form, so I am super excited to share this Instant Pot recipe with you. 

One thing that I’ve found with some Instant Pot recipes is you have to use the pressure cooker for one part of the recipe, then some other appliance or pan for the rest. You will be happy to know that Instant Pot Fettuccine is truly a one pot meal!

Step by Step: How to Make Fettuccine Alfredo in the Instant Pot 

Start by placing the fettuccine noodles in the inner pot and covering them with enough water so they are submerged. If the noodles don’t fit, break them in half before adding the water. 

Lock the lid in place, turn the valve to “Sealing” and cook on High pressure for 7 minutes. Perform a quick release and remove the cooked pasta and drain. Set aside. 

Change the function to Saute and add the butter. Once it’s melted, toss in the garlic and cook until fragrant (about a minute). 

Next, stir in the cream and heat to boiling. Add the Parmesan cheese and seasonings and cook until the sauce has thickened.

Pour the Alfredo sauce over the cooked noodles or add the noodles back to the pot and toss to coat evenly. At this point you can turn the Instant Pot off or select Warm if serving later.

If desired, top with additional shredded cheese and a little chopped parsley as a garnish. 

Can I Substitute Milk for Heavy Cream?

While it won’t be quite as rich and creamy you can substitute whole milk thickened with a little bit of cornstarch. We don’t recommend using 2% or fat free milk for this recipe.

Tips for Storing and Reheating Fettuccine with Alfredo Sauce

Leftover Alfredo should be stored in the fridge and is best when eaten within 3 days after cooking. 

When you reheat leftovers, you may need to thin it with a bit of milk, water, or cream. Also we typically reheat ours on the stove versus using the microwave. Take care not to overheat because the sauce will curdle if heated too long. 

What to Serve with Fettuccine Alfredo

While this is a one pot meal, we enjoy serving it with garlic bread, soup, a simple dinner salad, or a veggie side dish.
