Set Instant Pot to Sauté. Add 1-2 tablespoons of butter and after it melts, add the minced garlic with 1-2 teaspoons of chopped parsley.

Sauté for about 1 minute and then hit Cancel to shut off the sauté function. Scrape off any bits that might be stuck to the bottom, then add remaining butter, Broth (or water), Heavy Cream, Half and Half, Cream Cheese and Parmesan Cheese

Add Salt and Pepper (optional) to taste. I Like Roughly 2-3 teaspoons salt and 1-2 teaspoons of pepper.

Break the fettuccini noodles in half and add them to the instant pot.

Work the noodles so that they are as submerged as possible.

Place the lid and ensure your valve is set to “Sealing”.

Use Manual or Pressure mode and set it to 7 minutes.

Once the timer is complete, wait another 7-9 minutes before fully venting the pressure. (7-9 Minute Natural Release)

Carefully remove the lid and stir the fettuccine Alfredo until everything is combined well.

Let sit for 2-3 minutes to thicken

Garnish with your remaining parsley
