Ingredients
The 7 simple ingredients needed to make Instant Pot fettuccine alfredo are:
- Heavy cream
- Parmigiano Reggiano cheese (sub with parmesan cheese)
- Vegetable or chicken broth (or use water)
- Fettuccine pasta
- Shallot
- Garlic + butter
- Salt + pepper
Pre-shredded cheese will not melt smoothly into the sauce due to the preservatives added to it. It will likely turn rubbery or not dissolve fully.
So if you can't find a block of the real deal Parmigiano Reggiano, don't stress. It's more important to make sure that whatever cheese you use is freshly shredded by you.
Step-By-Step Directions
Instant Pot fettuccine alfredo is made in 3 easy steps.
- Set the Instant Pot to saute and add the butter. When melted, add the garlic and shallots and saute for 1 minute.
- Turn off saute and pour in the broth. Deglaze the bottom to ensure there is nothing stuck. Break the fettuccine noodles in half and add to the pot. Pour in the heavy cream, pressing down on the pasta to cover with the liquid. Add the salt and pepper.
- Seal the lid and set to pressure cook on high for 5 minutes. Complete a controlled quick release of the steam when finished. This means to gently hold down the vent so that the steam comes out slowly rather than at full force. At full force, heavy cream will eventually shoot out with the steam and make a big mess.
- Remove the inner pot and set on a trivet. Wait 3 minutes, then add the cheese 1 cup at a time, mixing to melt and incorporate into the sauce between cups. Season with additional salt and pepper if desired.
Serve immediately, garnished with fresh parsley or basil if desired.
💡 The general rule for pressure cooking pasta is to divide the lowest cook time on the package in half. Then subtract 1. For a more al dente pasta, subtract 2. Pressure cook on high for this amount of time.
If you'd like to add diced chicken, chop it into small pieces and cook with the butter during step 1 for 7-10 minutes, until cooked through. Add the garlic during the last minute.
You can also add shredded rotisserie chicken immediately before serving. Toss to coat with the sauce.
Cooking Tips
- Always shred the cheese and do not buy pre-shredded cheese
- Remove the inner pot from the outer pot and wait 3 minutes before adding the cheese. This will reduce the heat slightly and help to melt the cheese perfectly. If the cheese is added to the pasta when it's too hot, it will turn into rubbery strings.
The difference is that Parmigiano Reggiano is made in Italy while Parmesan cheese can be made anywhere. Essentially, Parmigiano Reggiano is the real version of Parmesan cheese, while the Parmesan cheese you find in local grocery stores is a close second.
The real deal, Parmigiano Reggiano, is best to use when making fettuccine alfredo. Parmesan cheese is the second best. But, we are so accustomed to using Parmesan cheese that you may not notice a big difference.
Parmigiano Reggiano has a deeply rich, nutty flavor. Parmesan cheese will taste slightly more acidic and salty.
Whether you use Parmigiano Reggiano or Parmesan cheese, always make sure that you buy a fresh block and shred it yourself.
Yes you can. Grated Parmesan will actually melt better than pre-shredded. Grated Parmesan tends to be pretty salty, so you may need to reduce the amount of salt.
Serving
This recipe yields 4 servings of 6 ounces of pasta and sauce. It will feed 3-4 people, depending on portion size.
Instant Pot fettuccine alfredo is best served immediately. When the sauce sits for a while, it will appear clumpy. There is no need to worry, though, as it will turn smooth when reheating.
Fridge Storage: will keep for 5 days in the fridge.
Freezer Storage: not freezer friendly.
Recipe
Instant Pot Fettuccine Alfredo
Equipment
Ingredients
- 4 tablespoon unsalted butter
- ¼ cup shallot diced
- 4 cloves garlic minced
- 16 oz fettuccine
- 2 cups chicken or vegetable broth or water
- 4 cups heavy cream
- ½ teaspoon black pepper
- 1 teaspoon salt
- 2 ½ cups freshly shredded Parmigiano Reggiano sub with Parmesan
- 4 tablespoon fresh parsley optional
Instructions
- Set the Instant Pot to saute for 3 minutes. Add the butter to melt and when the pot starts counting down add the diced shallot. Add minced garlic with 30 seconds remaining.
- Turn off saute and pour in the broth. Deglaze the bottom of the pot to ensure pieces of food are not stuck to the bottom.
- Break the fettuccine noodles in half and add to the pot. Pour in heavy cream, pressing down on the pasta to cover. Add salt and pepper. Seal the lid and set to pressure cook on high for 5 minutes. For a more al dente pasta, pressure cook for 3 minutes. *You can also cook for the amount of time you normally cook fettuccine if you have a specific tenderness that you like, without affecting the taste of the sauce.
- Complete a controlled quick release of the steam when finished (lightly press on the steam release valve in short bursts until all steam is released to avoid heavy cream spraying out and making a mess).
- Remove the inner pot to another surface. Wait 3 minutes, then add the cheese 1 cup at a time, mixing to melt and incorporate into the sauce between cups. Season with additional salt and pepper if desired. Serve immediately, garnished with parsley.
