Chicken Alfredo Rice Casserole is a warm and comforting dish you can prep ahead and bake just before serving. If you plan ahead and have extra cooked rice, a rotisserie chicken, and prepared Alfredo sauce, this recipe only takes a few minutes to stir together.

A blue plate has a serving of chicken rice alfredo casserole. You can see the red peppers and peas popping up through out the serving.

I first prepared this chicken alfredo rice casserole in the last couple of weeks before my second daughter was born.

I was busy prepping dinners for our freezer to help with life after baby's arrival.

What's nice about this particular rice casserole is that there's just the right amount of sauce to prevent it from getting mushy when you bake it.

The vegetables stay nice and crisp, the rice is firm, and the buttery breadcrumbs on top give a nice crunch.

You can use prepared Alfredo sauce, but I highly recommend making a batch of our homemade Alfredo sauce with cream cheese. Use one half of the sauce to make Alfredo pasta or a chicken spinach Alfredo pizza, and save the other half for this freezer-friendly casserole.

Ingredients

This may look like a lot of ingredients, but I have several tricks for keeping it easy and making quick work of the prep of this dish.

The Ingredients for Chicken Alfredo Rice are on the kitchen counter.
  • Shredded chicken
  • Alfredo sauce
  • Cooked rice
  • Frozen peas
  • Roasted red peppers
  • Basil & Crushed red pepper flakes
  • Bread crumbs
  • Grated parmesan cheese
  • Sliced almonds
  • Garlic salt

How to Make This A Quick Prep Recipe

Cooked Chicken:

The first key to cutting time is to use a rotisserie chicken.

One good sized chicken will provide 2 - 3 cups of shredded meat once the skin and bones have been removed.

I love to stock up on rotisserie chickens from Costco, pre-shred the meat, and store them in separate zip-top baggies in the freezer.

Then, I can thaw just what I need for a single recipe.

Cooked Rice:

You need about 4 cups of cooked rice (or 2 cups raw rice, then cooked) for this recipe.

I have 3 time-saving tricks for planning ahead for cooked rice:

  1. Chinese Takeout: Order extra containers of white rice when you do carryout. Keep them on hand for meal planning later in the week.
  2. Freeze Cooked Rice: You can cook and freeze rice for using later.
  3. Instant Pot Jasmine Rice: I can place 2 cups of jasmine rice in my Instant Pot mini and the 4 cups of rice I need is ready to use in the casserole by the time I've shredded the rotisserie chicken and chopped the peppers.

Alfredo Sauce:

A bowl of homemade alfredo sauce is waiting by the rice.

You can use jarred or prepared Alfredo sauce from the grocery store with a little milk to thin it out for this dish.

However, if you make our favorite homemade Alfredo sauce earlier in the week, you can save half of it for this recipe. It is SO MUCH better than the prepared kind and only takes a few minutes.

Instructions

Once you have those main ingredients ready to go, the rest of the recipe is SO easy to prep!

If you plan to bake and serve it right now, preheat your oven to 350°F.

In a very large mixing bowl, combine the rice, Alfredo sauce, shredded chicken, diced roasted red peppers, frozen peas, sliced almonds, dried basil, and crushed red pepper flakes.

All the ingredients for the casserole have been prepped and placed in a large mixing bowl.

This is a very thick mixture.

If you don't have a very large mixing bowl, you may prefer to stir it in stages:

  • First, the alfredo sauce and seasonings
  • Then the alfredo sauce and the rice
  • Then add the chicken and peppers
  • Then add the peas and almonds

Be sure to check the recipe card for a note on whether or not you need to add milk at this point.

Spray a baking dish with cooking spray and spread the mixture out evenly.

The ingredients have been mixed together and spread into a casserole pan

Hint: You can use a 2-quart covered casserole dish or a 9 x 13-inch baking dish.

The 9 x 13-inch dish will give more crispy edges, a thinner breadcrumb layer, and may bake more quickly.

The deeper casserole dish we used leaves more of a creamy center but can take longer to heat in the center.

Bake the covered casserole for 30 minutes.

Meanwhile, prepare the breadcrumb topping.

The ingredients for the breadcrumb topping are ready to be mixed.

Mix together the breadcrumbs, grated parmesan, melted butter, garlic salt, and dried parsley until the breadcrumbs are evenly dampened.

Uncover the casserole, spread the breadcrumb mixture evenly over the top and bake for an additional 20 minutes.

The chicken alfredo rice casserole sits on the stovetop and has had the breadcrumb topping sprinkled over the top to finish baking.

The breadcrumbs should be golden brown and the center of the casserole piping hot.

Serve warm.

The baked casserole has a serving spoon scooping out a portion onto a blue plate.

Variations

Frozen peas and roasted red peppers are so easy to keep on hand, but there are several substitutions and variations you could also play with:

  • Sundried tomatoes
  • Chopped broccoli
  • Chopped asparagus

Freezer Tips

If you plan to freeze the casserole, simply assemble it as instructed but then stop before baking.

Spread the mixture into a freezer-safe baking dish, top with the breadcrumbs, cover with aluminum foil, and freeze.

Thaw the dish in your fridge overnight. Bake covered for 30 minutes, uncover and finish baking for 15 - 20 minutes.

  3. How can you not like Alfredo sauce?! It's cream and cheese! And butter! I mean, I can see not being *able* to eat it due to cholesterol or lactose or fat or self-respect issues, but not *wanting* to eat it?

  4. Tiffany this is great! I've been looking at what recipes freeze back well for when I'm doing the same thing later this summer before our twins arrive. Thank you!
