Mississippi Chicken Casserole–an Instant Pot chicken and noodle dish with ranch seasoning, chopped pepperoncinis, sweet corn, and green beans all simmered in a zesty pepperoncini broth and topped with melted cheddar.

Mississippi Chicken Casserole
Mississippi roast is made with pepperoncinis and ranch dressing mix and this chicken noodle casserole incorporates those flavors into a yummy meal. I didn’t have any thawed chicken so I incorporated the frozen chicken into the cooking process. I cooked the chicken first in the pepperoncini juice to infuse it with flavor. Then I added in the noodles and vegetables that only require a short cooking time. It worked out well and didn’t require much work from me…which I love 😉
Ingredients/Substitution Ideas
- Olive oil–or canola oil
- Onion–yellow or white
- Chicken broth–or water and Better than Bouillon chicken base

Steps
Turn Instant Pot to saute setting. When display says HOT add in the oil and swirl around. Add in the onion and saute until soft and translucent.

Move chicken to a cutting board and set aside.

Notes/Tips
- Serve with a green salad and fresh fruit.
- Use full-fat sour cream or Greek yogurt for the creamiest texture.
- You can also make this recipe with cooked chopped rotisserie chicken. Do away with the first pressure cooking time and just pressure cook the noodles, chicken, corn and beans for 1 minute with a 5 minute pressure cook time.
- I used my 6 quart Instant Pot*. You can also make this in a 3 or 8 quart pot.
- Store leftovers in an airtight container* in the refrigerator for up to 4 days or in the freezer for up to 3 months.
