Instant Pot Sandy’s Casserole–pasta in a creamy sauce with chicken, mushrooms, onions, spinach, garlic and topped with crispy fried onions.

Instant Pot Sandy’s Casserole
Today’s recipe is my take on a recipe I found on food.com. My family ate this all up. After Skyler had his first bite he said, “I’ma eat more of that pasta…it’s bussin’!” I liked how easy this was to make and I had all the ingredients I needed at home.
This recipe is quite versatile. Switch up the type of pasta you use, the type of cream soup, whether your chicken is cooked or raw, spinach or kale, etc. This recipe is awesome because you can really customize it to your own family’s preferences.
Ingredients/Substitution Ideas
- Butter–or olive oil
- Onion–fresh or frozen. You can also use shallots.
- Mushrooms–I used white button mushrooms. You can also use canned mushrooms.
- Salt and pepper
- Garlic cloves–I used fresh but you can also use jarred
- Chicken broth–or water and Better than Bouillon Chicken Base
- Bowtie pasta–or penne, macaroni, etc.
- Chopped, cooked chicken (I used rotisserie chicken)–or 1 pound raw chicken, cut into cubes
- Cream of chicken soup–or cream of mushroom soup or 4 ounces of cream cheese
- Spinach–I used fresh but you can use frozen too
- Milk–to thin it out
- French fried onions–the crispy topping you put on green bean casserole. I usually find these at the store next to the green beans.
Steps
Turn Instant Pot to saute setting. When display says HOT add in the butter and let it melt. Add in the onion, mushrooms and a pinch of salt and pepper. Saute for 3 minutes. Add in the garlic and saute for 30 seconds.

Pour in the broth and scrape bottom of pot so that nothing is sticking. Turn off Instant Pot.

Sprinkle in the pasta.

Dump chicken, cream of chicken and spinach on top. Don’t stir.

Cover Instant Pot and secure the lid. Make sure valve is set to sealing. Set the manual/pressure cook button to 4 minutes. When time is up let pot sit for 5-10 minutes and then move valve to venting. Remove the lid.

Stir in the milk. Scoop onto plates and top each serving with 2 Tbsp of the crispy french fried onions. I sprinkled parmesan cheese on top of mine.

Notes/Tips
- Serve with garlic bread and a side salad. We love the Olive Garden brand Italian dressing.
- I used my 6 quart Instant Pot*. You can also make this in a 8 quart pot.
- If you don’t want to use cream of chicken soup you can use 4 ounces of cream cheese instead.
- You can use kale instead of spinach, if you prefer. Another option is to stir in some peas after the pressure cooking time is up.
- There are so many others types of pastas that you can use instead of bowties. To figure out pressure cooking time take the time on the back of the box and divide by two and then subtract 1 minute. For example if it says to boil 10 minutes then you’d divide by 2 (5) and then subtract 1 (4 minutes of pressure cooking time).
- 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 spinach are Instant Pot Dude Pasta and Instant Pot Garlic Parmesan Chicken.
