Lone Star Chicken Casserole–a creamy chicken sauce with Rotel served over rice. An easy dinner you can make in the Instant Pot or slow cooker.

Lone Star Chicken Casserole
This is a different take on king ranch chicken casserole. Instead of tortillas I decided to use rice as the carb base. Skyler is always weird about what he terms “soggy tortillas” so I decided to just make the king ranch chicken sauce and pour it over a bed of rice instead of baking it with tortillas. It was an easy and yummy dinner that satisfied all of us!
Ingredients/Substitution Ideas
- Canola oil–or olive, vegetable
- Onion–yellow, white
- Celery
- Garlic powder
- Chili powder
- Cumin
- Chicken broth–or water and Better than Bouillon chicken base
- Boneless skinless chicken thighs–frozen or fresh
- Kosher salt
- Rotel tomatoes–I used mild
- Cream of chicken soup–or cream of mushroom
- Hot cooked rice, for serving
Steps
Turn Instant Pot to saute setting. When display says HOT add in the oil and swirl around. Add in the onion and celery and saute for 4 minutes. Stir in the garlic powder, chili powder and cumin.

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

Add in the chicken thighs. Sprinkle the salt onto the chicken. Dump Rotel and cream of chicken over the chicken (try to keep cream of chicken on top of the chicken and not touching bottom of pot).

Cover Instant Pot and secure the lid. Make sure valve is set to sealing. Set manual/pressure cook button to 12 minutes. When time is up let pot sit for 10 minutes and then move valve to venting. Remove the lid.

Move chicken to a cutting board and chop it up. Stir the chicken back into the pot.
Serve chicken and sauce over hot cooked rice.

Notes
You can cook rice at the same time as the chicken using the pot-in-pot method. This technique involves placing rice in a separate heatproof container that sits on a tall trivet inside the Instant Pot, allowing both the rice and chicken to cook together without mixing. To do this, add 2 cups of white rice and 3 cups of water to a heatproof container that fits inside the Instant Pot (a stainless steel pan works well*). Then, add the chicken ingredients directly to the bottom of the Instant Pot. Place the container of rice on top of the chicken using a tall trivet* to keep it elevated. Secure the lid, set the valve to sealing, and cook according to the recipe instructions. Once done, carefully remove the rice container—it will be perfectly cooked and ready to serve alongside the chicken.
