Hey everyone, Jenn here! This chicken and rice casserole is one of my kids’ favorite pressure cooker meals. They love the combination of creamy rice, melted cheddar, and perfectly steamed broccoli. It’s a regular menu item at my house, especially because it’s so easy to make on busy nights. 

A bonus is that this cheesy casserole also makes tasty leftovers, so go ahead and double the recipe, and you’ll have a satisfying lunch to enjoy the next day. 

Update: Things certainly have changed in the pressure cooking world since we first posted this recipe in 2013! I’ve updated the recipe so that it works even in the newest pressure cooker models, including the Instant Pot Evo.

How to Make Cheesy Chicken and Broccoli Casserole in an Instant Pot / Pressure Cooker

This Cheesy Chicken and Rice Casserole recipe will work in any brand of electric pressure cooker, including the Instant Pot Evo, Ninja Foodi, or Power Pressure Cooker XL.

Did I mention how easy this one-pot meal is?

You’ll start by browning the cubed chicken and diced onions using the Sauté function on your pressure cooker. Then deglaze the pot with chicken broth, add the white rice and seasonings, seal up the lid, and cook at High Pressure for just 3 minutes.

Once you release the pressure, thicken the rice into a smooth, creamy sauce with a quick slurry of cornstarch and water. 

💡 Tip: If you find that your rice is still a little watery, you can simmer for a couple more minutes or add a bit more cornstarch. 

Finally, add the broccoli and steam until just crisp-tender.

Can I Make Chicken and Rice Casserole with Frozen Broccoli?

Yes! This Instant Pot / Pressure Cooker recipe works with fresh or frozen broccoli. 

🥦 To use frozen broccoli: Allow the pressure to release as described in the recipe. Turn off the pressure cooker and carefully remove the lid. Then stir in the frozen broccoli and place the lid back on the pressure cooker (keep the pot turned off).

The residual heat inside the pressure cooking pot will cook your broccoli in just a few minutes.

Ingredient Substitutions and Swaps

This Creamy Chicken and Rice Casserole is very versatile. You can really use whatever vegetables you have on hand.

If you don’t have broccoli, frozen peas, cauliflower, or other veggies will work just the same. 

Can I Make Instant Pot Chicken Broccoli and Rice Casserole Ahead of Time?

This is a great make-ahead meal!

When making ahead, I keep the broccoli separate from the cheesy rice casserole. 

That way, when I reheat and serve, I can quickly steam a fresh batch of broccoli to stir into the casserole.

Ingredients

  • 1 tablespoon vegetable oil
  • 1 pound boneless skinless chicken breasts, cubed (about 2 large breasts)
  • 1 onion diced
  • 1 cup white rice
  • 2 cups reduced-sodium chicken broth
  • 1 teaspoon salt*
  • 1/4 teaspoon pepper
  • 1/4 teaspoon garlic powder
  • 1 tablespoon cornstarch
  • 1/2 cup milk
  • 1 1/2 cups shredded cheddar cheese
  • 2 cups small broccoli florets

Instructions

  • Select Sauté to preheat the pressure cooking pot. When hot, add oil, cubed chicken, and onion. Sauté, stirring frequently, until onion is translucent, about 3 minutes.
  • Add chicken broth and stir to scrape the brown bits from the bottom of the pan. Add salt, pepper, and garlic powder and stir to combine. Add the rice and stir to ensure it’s distributed evenly. Lock the lid in place. Select High Pressure and 3 minutes cook time. 
  • When the cook time ends, allow the pressure to release naturally for 7 minutes, then finish with a quick pressure release. When the valve drops, carefully remove the lid.
  • In a small bowl, whisk together the cornstarch and milk. Select Sauté and add the milk mixture and broccoli. Stir and simmer until thickened, about 1 to 2 minutes. Turn off the pressure cooker.
  • Add the cheddar cheese a handful at a time, stirring between additions until well combined and melted. Place the lid back on the pressure cooker for 3 to 5 minutes, until the broccoli reaches desired tenderness.

Notes

*Omit the salt if using regular chicken broth.
