My Italian relatives would be so mad at me for what I’m about to say but here goes. You ready?

This Instant Pot Alfredo is the easiest and the best Alfredo I’ve ever had. I know, I know. In an Instant Pot!

I’m the first to admit that I am the biggest Instant Pot skeptic but this pasta recipe is a game changer for me.

I honestly don’t know if I would make Alfredo on the stove again and it makes me love my Instant Pot for something other than soups and cauliflower.

It’s an easy one pot meal with almost no prep other than dumping everything in the pressure cooker and pressing start. There’s no stirring, no dirtying multiple pots and pans and no hoping that your sauce thickens and coats the noodles.

(Spoiler: It coats them perfectly because the noodles are cooked in the sauce.)

It’s just simple pasta perfection and I know you’ll love it.

Ingredients

To make this you’ll need:

• Butter- Go for unsalted butter in this so you can better control how salty the dish is. The cheese adds a lot of saltiness so you won’t want the extra.
• Garlic- Fresh, pressed garlic cloves will give better flavor than dried garlic powder
• White wine- Any wine you’d drink. I wouldn’t recommend skipping it as it adds flavor and richness.
• Water- Here’s the deal. I NEVER recommend water when you have the option to use another more flavorful liquid like broth. BUT I have tried this with broth and I found the broth to be too intense of a flavor. It made the whole dish seem like cup o soup noodles, which is not what we are going for here.
• Heavy cream- You can add it right to the Pot and cook the noodles in it. Don’t substitute milk or lower fat cream here. It’s Alfredo, you want maximum richness.
• Fettuccine- A whole 16 ounce package of fettuccine, broken in half.
• Parmesan cheese– Go for the good stuff you can buy in the specialty cheese case for best flavor, but the plain old can of Parm will work fine too.

How to Make Instant Pot Fettuccine Alfredo

This recipe is almost embarrassingly easy to make and the perfect recipe for Instant Pot beginners to try.

To make it:

Add the liquid and butter to the inner liner of the pot.

To start, add the butter, pressed garlic, wine, water and heavy cream into the inner liner of the Pot. Stir it together.

Break the noodles in half and add them to the liquid, crisscrossing them over each other.

Add the broken in half noodles to the liquid. Criss cross them on top of each other by making small bundles of noodles and laying them in so they form an x. Push the noodles down so the liquid covers them all.

Pressure cook the fettucine.

Secure the lid on the Pot and make sure the valve is set to seal. Pressure cook on high for 6-7 minutes depending on how firm you like your noodles. After the Pot beeps, let the pressure naturally release for 5 minutes. Then quick release the remaining pressure.

Stir in the cheese.

Once the pressure is released, remove the lid. Everything will look a little liquidy and that’s ok. Add the cheese and stir. The sauce will quickly thicken up.

If it gets too thick, add another splash of heavy cream. Serve and top with more cheese if desired and fresh herbs. Enjoy!

Saving and Reheating

I don’t recommend saving and reheating fettuccine Alfredo. The sauce tends to separate in the fridge and loose that luscious creaminess when you reheat it. 

FAQs

Tips and Tricks

• Don’t worry about it if your sauce looks thin at first. The first time I made this, I was horrified initially by the runny sauce. However, once you add in the cheese the starchiness of the liquid will thicken the cheesy sauce right up.
• If the sauce is too thick, stir in a bit more heavy cream at the end.
• I love adding fresh herbs at the end of this. It’s so good with fresh basil and parsley.
• Slice up some Easy Italian Grilled Chicken and serve it on top for a chicken alfredo situation.
• Serve it with some garlic bread to soak up all the creamy sauce.
• Do your own tour of Italy Olive Garden style and serve it with a side of authentic Italian meatballs or Italian Spicy Meatballs in real Italian tomato sauce.
• Or add some lobster tail to it if you are feeling fancy and make Lobster Alfredo
