My kids love spaghetti but I needed a little change. This Instant Pot white chicken spaghetti recipe is perfect for something a bit different. You will love the cheesy goodness this easy pressure cooker recipe brings to the table.
I have a confession to make, I am not the biggest fan of tomato sauce. I mean, when it is good I enjoy eating it, but for the most part, I prefer white sauces. My family and I have been loving our pressure cooker and have been making some wonderful Kid-Friendly Instant Pot Recipes but I was ready for a little bit of a change with our regular spaghetti recipe. It was time to create an Instant Pot White Chicken Spaghetti meal that we would all love.
White Chicken Spaghetti
White chicken spaghetti has been a favorite pasta dish of mine ever since I was a little girl. I grew up eating mushrooms and cream sauce, so I thought they would be perfect for an easy chicken spaghetti, and I was right!
The great thing about this recipe is that you can adapt it very easy to fit your family’s tastes. If your kiddos aren’t a fan of mushrooms, throw in some peas or broccoli! If you have leftover rotisserie chicken in the fridge, use that instead of cubed chicken breast. I am all about making recipes tasty and easy for us busy parents like this amazing Instant Pot Crack Chicken recipe.
This white chicken spaghetti is going to be a family classic in no time. In fact, my kids have asked for it more times than my personal favorite Instant Pot Cashew Chicken! Another pasta favorite is our family-friendly Instant Pot Cheeseburger Macaroni recipe, so be sure to check that one out!

Instant Pot White Chicken Spaghetti Recipe
Ingredients:
- 1lb chicken breast, cubed
- 2 tablespoons olive oil
- 1/2 cup chopped onion
- 1 tablespoon minced garlic
- 1 teaspoon basil
- 1 teaspoon oregano
- 1 teaspoon salt
- 1/2 teaspoon pepper
- 8 ounces sliced mushrooms (optional)
- 4 cups chicken broth
- 8 ounces thin spaghetti pasta (uncooked)
- 1 tablespoon butter
- 4 ounces cream cheese, cubed
- 1 cup half & half
- optional: 2 tablespoons cornstarch mixed with 1/4 cup cold water (to thicken the sauce)
Directions:
Add chicken, oil, onion, and garlic to the instant pot. Sautee until chicken is browned. Add spices and mix well. 
Stir in mushrooms, broth, and pasta. 
You may have to break pasta in half as you’ll want it to be covered with the liquid. Mix well.
Place the lid on the Instant Pot and seal it. Close the pressure release valve. Set the Instant Pot to manual 8 minutes (high). When cooking cycle is complete, quick release the steam and open the lid.
Carefully stir in butter and cream cheese until melted. Add cream and stir well. 
The mixture will continue to thicken as it cools, or, if desired, add cornstarch mixture and return the pot to sautee until spaghetti boils and begins to thicken.

Can this recipe be doubled? If so does the cook time stay the same? Thank you!
Yes and yes, the cooktime will be the same.
Can I substitute milk for the half and half?
Yes, but it won’t be as rich or thick. You could thicken it with a cornstarch slurry.
