Tips + Tricks

No. 1 --> As with any pasta being cooked in the Instant Pot, it's super important to toss the noodles in willy nilly. The more they touch, the more likely they will stick. Lay the noodles in the pot crosshatch.

No. 2 --> Avoid the dreaded burn notice by layering your ingredients properly. I know I just say throw the noodles in, but there is a method to the madness that is Instant Potting.

Key ingredients

Chicken breast: We always have chicken breast in the freezer, it's one of the most versatile foods out there, even though we don't actually eat much chicken!

Cream cheese: Philadelphia cream cheese adds so much creaminess to the sauce that it just is a must in this recipe.

Marinara sauce: I love a very basic tomato, garlic, basil marinara sauce for all my spaghetti recipes, it allows the other flavors in the dish a chance to shine without competing.

How to make Creamy Instant Pot chicken spaghetti

  1. Add water to the pot of your Instant Pot. Layer in the noodles, they must be placed in the pot spread out, in a crosshatch pattern.
  2. Slice the chicken breasts in half, and place them on top of the noodles.
  3. Add the diced onion, bell pepper, and garlic cloves.
  4. Top with the sauce.
  5. Close the Instant Pot and set the valve to the sealing position. Cook on high pressure for 4 minutes. Do a natural pressure release of 5 minutes before quick releasing the remainder of the steam.
  6. Open the lid and remove the chicken. Add the cream cheese. Close the lid again and allow the cheese to soften while shredding the chicken. Return the shredded chicken to the Instant Pot.
  7. Stir in the milk and cream cheese until completely combined.
  8. Serve hot.

Batch + Storage Information

Batch:

This recipe makes about 10 - 12 cups.

I find this to be enough for 2 meals for our family of 4 and then some.

It can be doubled, easily, but you'd definitely need the 8QT Instant Pot.

Storage:

If you've got leftovers, your Instant Pot chicken spaghetti can be stored in the fridge for 2 - 3 days in an airtight container. Reheat it in the microwave - add a little milk or cream to loosen the sauce as required.

Instant Pot: Spoiler, I don't actually have an "Instant Pot" brand instapot. I have a Breville FastSlow Pro and I love it! That said, my mom and sister both own Instant Pots and love them too!
