Costco Rotisserie Chicken Casserole (Instant Pot)
Probably the best deal you can buy these days is a rotisserie chicken from Costco. It costs around $5. You can’t even buy a whole, uncooked chicken for that price. Let alone the fact that it is cooked and seasoned to perfection and ready to enjoy the moment you get home. Buy two next time you go! Eat one for dinner and take the meat from another one and use it in another recipe like this chicken casserole!
This recipe is versatile. You can use lots of different types of pasta, cream of chicken soup or cream cheese and a cheese of your choice. It’s creamy and delicious! You’re going to love how it makes enough for some now and leftovers later. My kids have been enjoying the leftovers immensely.
Ingredients/Substitution Ideas
- Chicken broth–water and Better than Bouillon Chicken Base
- Cavatappi pasta–you can also use penne or farfalle
- Dry ranch dressing mix–I like Hidden Valley
- Rotisserie chicken–the Costco chickens are probably the cheapest and the best. This is about 4 cups of cooked/shredded chicken.
- Cream of chicken soup–or another cream of soup you like. You can also use 4-8 ounces of cream cheese (depending on how creamy you like it).
- Bacon crumbles–I find these in the salad dressing aisle. You can also fry up some bacon and crumble it instead. I like using my air fryer* to cook bacon!
- Monterey jack cheese–of another cheese you like (pepper jack, colby jack)
- Green onions–optional
Steps
This is such an easy dump and go recipe and it feeds a crowd.
- Dump ingredients into the pot: Dump chicken broth and pasta into Instant Pot. Sprinkle the ranch on top. Dump the chicken and cream of chicken soup on top. Don’t stir.
- Pressure cook: Cover Instant Pot and secure the lid. Make sure valve is set to sealing. Set the manual/pressure cook button to 3 minutes. When time is up let the pot sit for 5-10 minutes and then move valve to venting. Remove the lid.
- Stir in remaining ingredients: Stir well. Stir in the bacon, cheese and onions.
- Serve: Scoop onto plates and serve.
Notes/Tips
- This recipe makes a lot! You can easily halve the recipe (cut all ingredients in half and use the same cooking time). Another idea is to eat half now and spread the other half in a baking dish and cover tightly with foil and freeze. When you’re ready to eat it place it in the oven and bake for 45 minutes at 350 degrees. Remove the foil and bake for 10 more minutes.
- Serve with a green salad or some roasted broccoli.
- I used my 6 quart Instant Pot*, you can also use your 8 quart pot. For the 3 quart pot, halve the recipe.
- Store leftovers in an airtight container* in the refrigerator for up to 5 days or in the freezer for up to 3 months.
- Other recipes you can make with dry ranch dressing mix are Instant Pot Mashed Ranch Cauliflower, Instant Pot Ranch Chicken Taco Rice, Instant Pot Parmesan Ranch Potatoes, Instant Pot Garlic Cheddar Chicken, and Instant Pot Beef And Cheddar Ranch Potatoes.

Thanks so much Kathy!!
Thanks for dinner again tonight Karen! 😉😜It was really good!
★★★★★
yay!!!!! Thanks for the 5 stars 🙂
Sorry, I just noticed in your notes that you say it is about 4 cups of chicken. That answers my question.
Karen, the ingredients say “Meat from 1 rotisserie chicken, shredded”. Do you really mean the WHOLE chicken? Seems that would be an awful lot of chicken. Just don’t want to overdo on that ingredient. TIA
I made this last Saturday and it’s a big winner in my house. We love it and no doubt will make it again and again.
I didn’t have any Cream of Chicken soup but did have a Garlic Cream of Mushroom. It still came out terrific.
★★★★★
Oh, I bet garlic cream of mushroom was even better!
I actually had everything I needed to make this tonight, so I did. It was very easy, and very tasty. I halved the recipe, as I live alone; but, it still made a lot! The pasta wasn’t mushy, but it was soft. Since I will have to reheat leftovers, I’m wondering if I could have done with two minutes, or not have let it natural release for four minutes. I’m sure I would have had to release the pressure slowly, so as not to have it spray everywhere. Any thoughts on that? Thanks!
★★★★★
Oh yes I think that would work just great!
I always worry about any type of pasta (in an instant pot recipe) to be overcooked and not “al dente” as I like. Do you think that it would be possible to cook the pasta separately and then stir it into the pot at the end?
I would just cook the whole thing on the stove if I were you. The chicken is already cooked so there is no need to pressure cook if you are not cooking the pasta in the instant pot.
