pro tips for the best chicken casserole

A few pro tips for you as you make this delicious chicken broccoli rice casserole! It’s an easy recipe but you’ll want to be sure that you follow it in order to get the best results.

Make sure you deglaze the bottom of the pot to avoid the burn message on your Instant Pot. To deglaze the pot, add the broth to the hot pot after you sauté the chicken, garlic and onion. Scrape the bottom of the pot to remove any cooked-on bits.

Can I use frozen broccoli instead of fresh broccoli? Yes, you can! Just make sure you thaw it out completely before putting it in the Instant Pot. Drain out any liquid after thawing.

Do not turn the Instant Pot on after you add the broccoli. The broccoli will cook with the residual heat. It takes about 10 minutes with the IP lid closed to get the broccoli to a tender-crisp stage. If you like your broccoli cooked softer then let the pot sit for 12 minutes.

You can add cooked broccoli at the end if you don’t want to wait the extra 10 minutes. If you want to make steamed broccoli on the stovetop or in the microwave then do that while the rice mixture is cooking.

Instant Pot Chicken Broccoli and Rice Casserole

Yield: 5 to 6 servings
Prep Time: 8 minutes
Cook Time: 4 minutes
Additional Time: 10 minutes
Total Time: 22 minutes

This Instant Pot chicken broccoli rice casserole is cheesy, creamy, comfort food. It comes together in a flash and it is made completely from scratch.

Ingredients

  • 2 tablespoon olive oil
  • 1 onion
  • 2 garlic cloves (or 1 teaspoon garlic powder)
  • 2 boneless skinless chicken breasts, sliced or cubed
  • 1 teaspoon dried oregano
  • 3/4 teaspoon salt
  • 1/4 teaspoon pepper
  • 2 cups chicken broth
  • 1-1/2 cups white rice (uncooked)

After the rice and chicken finish cooking:

  • 3 tablespoons butter
  • 3 tablespoons flour
  • 1-1/2 cups milk
  • 3 to 4 cups broccoli florets
  • 2 cups shredded cheddar cheese

Instructions

  1. Press the saute function and add the olive oil. When the oil is hot, add the onion and saute until it is soft. Add the garlic and stir until fragrant, about 30 seconds.
  2. Add the chicken oregano, salt, and pepper. Cook until it starts to turn white. Turn off the saute function.
  3. Add the broth then scrape the bottom of the pot to remove any cooked-on bits (this will prevent the burn notice).
  4. Add the rice and push it down into the liquid. Place the lid on the Instant Pot and make sure the pressure valve is in the sealed position. 
  5. Set the function to high pressure for 4 minutes. 
  6. When finished cooking, allow the Instant Pot to release pressure naturally for 10 minutes.
  7. While the rice is cooking, make the sauce. Melt the butter in a saucepan. Whisk in the flour and stir for 2 minutes to cook the flour mixture. 
  8. Slowly whisk in the milk, stirring as you go. Continue to whisk until the mixture is smooth and thick. 
  9. After 10 minutes of natural pressure release, let the rest of the pressure out of the Instant Pot manually. 
  10. Stir in the broccoli, cream sauce and 1-1/2 cups of the cheese. Sprinkle the rest of the cheese on top then immediately replace the lid. Do not turn the Instant Pot on. Just let the casserole sit with the lid closed for 10 minutes. The residual heat will cook the broccoli.

Notes

  • Make sure you deglaze the bottom of the pot to avoid the burn message. To deglaze the pot all you do is add the broth to the hot pot and scrape the bottom of the pot to remove any cooked-on bits. Do this to prevent the burn message.
  • If you use frozen broccoli make sure you thaw it first and drain the liquid.
  • You could also add cooked broccoli at the end instead of raw broccoli. If you add cooked broccoli, you will only need to let the casserole sit for 3 minutes to melt the cheese.

Made today for this evening, very delish! As we don't have this piece of kitchen equipment I improvised. Used my slow cooker. I omitted the onions and added a teaspoon of English mustard to the cheese sauce (we do this in the UK)and also dome double cream with the milk. The whole recipe turned out very well and was like a creamy cheesy risotto and so very easy to make.

Thank you a hit in our house!
