expert tips

  • Be sure to cover the baking dish with foil tightly for baking. This will create steam inside the baking dish so that the Rice-a-Roni is cooked perfectly.
  • Sprinkle over crushed Ritz crackers for a little extra crunch. Always toss them in butter so they toast a little bit in the oven to become extra crunchy.
  • Use rotisserie chicken for ease. This keeps the prep time to 15 minutes. I even shred mine using a stand mixer or hand mixer to avoid making a mess.
  • Add as many veggies as you’d like. I suggest peas and broccoli, but you can also add green beans, carrots, and greens like spinach or kale.
  • Make a homemade cream of chicken soup. If you are looking to control the sodium in the soup, make your own cream of chicken soup. Melt 3 tablespoons butter in a saucepan over medium heat. Whisk in ⅓ cup all-purpose flour and cook for 1 minute. Whisk in ⅓ cup milk and ⅓ cup chicken broth until well combined. Season with ¼ teaspoon onion powder and salt and pepper to taste. Stir and cook for 1-2 minutes or until thickened and creamy.

storage

Store any leftover Rice-a-Roni Chicken Casserole in an airtight container in the fridge for up to 3 days. You can easily freeze it too for up to 2 months, just thaw before reheating.

When it comes to reheating, use the microwave or oven and allow to warm through. It’s also an easy casserole to make ahead of time if you want to bring it to a potluck or just make dinner easier on a busy weeknight.

Notes

Storage: 
Store any leftover Rice-a-Roni Chicken Casserole in an airtight container in the fridge for up to 3 days. You can easily freeze it too for up to 2 months, just thaw before reheating.
When it comes to reheating, use the microwave or oven and allow to warm through. It’s also an easy casserole to make ahead of time if you want to bring it to a potluck or just make dinner easier on a busy weeknight.
Tips: 
  • Be sure to cover the baking dish with foil tightly for baking. This will create steam inside the baking dish so that the Rice-a-Roni is cooked perfectly.
  • Add the cheese towards to the end. You’ll want the casserole to cook first, then sprinkle the cheese over just to melt for even gooeyiness in every bite.
  • Sprinkle over crushed Ritz crackers for a little extra crunch. Always toss them in butter so they toast a little bit in the oven to become extra crunchy.
  • Use rotisserie chicken for ease. This keeps the prep time to 15 minutes. I even shred mine using a stand mixer or hand mixer to avoid making a mess.
