Ingredients you will need
Here is a quick snapshot of the ingredients you'll need. Scroll down to the recipe card where you'll find exact measurements.
- Parmesan cheese - you can use the pre-shredded kind or shred it yourself. You can also mix it up and add a little Asiago cheese as well for your Instant Pot Fettucine Alfredo.
- Cream cheese - I like to use full-fat but reduced-fat cream cheese will work as well. If you want to add additional flavor you can add some Boursin cheese in place of the cream cheese or herb-flavored cream cheese.
- Pasta - can be easily doubled. If you don't have Fettucine noodles then linguine or spaghetti will work as well. You may have to adjust the time.
- Water - I prefer to use water to cook the noodles but you can also use chicken or vegetable broth. You can also add a little garlic bouillon as well to the pasta water to kick it up a notch.
How to make this
Step 1: Cooking the Fettucine pasta
The first step is to cook the pasta. Break the pasta in half, and place it in the Instant Pot in a crisscross fashion. Pour the olive oil evenly over the top, and then pour the water over the pasta.
Cook on high pressure for 5-minutes then follow with a controlled quick release. A controlled quick release means you release the pressure in short bursts. This will make sure that you don't have pasta water spraying out all over your kitchen.
If you used a different type of pasta that's okay. You will need to adjust the cooking time to half of the lowest recommended time minus one minute for perfect pasta.
Once the pressure is released using a pair of tongs or a fork to toss the pasta in the pasta water. Reserve ½ cup of the pasta water, and then drain the pasta of the remaining pasta water.
Step 2: Making the alfredo sauce
Set the Instant Pot to saute. Add the butter, cream cheese, heavy whipping cream, reserved pasta water, Parmesan cheese, garlic powder, and pepper to the Instant Pot. Stir or whisk until everything is melted and combined. Turn off the saute function.
Add the pasta back to the pot and toss with the sauce until it is well coated. Don't worry if it seems a little thin since it will thicken as it stands. Sprinkle finished plates with parsley prior to serving.
If using different pasta for your Instant Pot Fettucine Alfredo be sure to adjust the cooking time if needed.
If you want to add chicken to this cut it into bite-sized pieces or strips. Place under the pasta in the Instant Pot prior to cooking. There must be at least a 4-minute cook time for the chicken to be properly cooked.
If you want to add shrimp to this instead you can add frozen shrimp with a minimum 4-minute cook time as well.
You can also add to the pasta at the end some spinach, broccoli, and some cooked chicken or shrimp. Kick up the heat or flavor by adding sauteed shallots or fresh garlic along with some hot red pepper flakes.
Alfredo isn't thought of as an authentic dish and has several ingredients like Parmesan and cream. Carbonara is an authentic Italian dish comprised of eggs, cured pork or bacon, and lots of cheeses.
If you're a fan of the movie 'The Holiday' then yes you definitely know it is. This is an easy dish you can feed a crowd before the big feast on Christmas day making it a perfect holiday eve dinner.
