What Makes This Recipe Special

Truly no-fuss prep: There is no stovetop work required. You dump the ingredients into your baking dish, give everything a quick stir, and let the oven do all the heavy lifting.
One-dish cleanup: Everything bakes together in a single casserole dish, which means fewer dishes and more time to relax after dinner.
Creamy Chicken Alfredo flavor: The classic combination of Parmesan, garlic, butter, and cream infuses every bite with that iconic Chicken Alfredo taste you love, now in hearty casserole form.
Family-friendly and flexible: Kids adore it, adults go back for seconds, and the recipe is easy to adapt for different tastes and dietary needs.

Key Ingredients

Boneless skinless chicken breasts: Cut into bite-sized pieces so they cook evenly and distribute throughout the casserole without leaving dry spots.
Long-grain white rice: Uncooked rice goes straight into the dish and absorbs all that savory Alfredo liquid as it bakes, becoming perfectly tender.
Jarred Alfredo sauce: A good-quality store-bought Alfredo sauce is the shortcut that makes this a true dump-and-bake recipe. Look for one with real Parmesan and cream for the best flavor.
Chicken broth: Adds extra savory depth and ensures the rice has enough liquid to cook through completely during baking.
Garlic powder and Italian seasoning: Simple pantry seasonings that boost the flavor without any extra effort.
Shredded mozzarella cheese: Melted over the top during the last few minutes of baking for that golden, gooey finish.
Grated Parmesan cheese: Stirred into the casserole and also sprinkled on top for a salty, nutty punch that ties the whole dish together.
Salt and black pepper: Season to taste, keeping in mind the Alfredo sauce already carries a good amount of sodium.

Using the right baking dish and quality ingredients makes a big difference in how evenly this casserole cooks and how creamy the final texture turns out.

Equipment

9x13 inch baking dish
Aluminum foil
Cutting board and knife

Ingredients

1.5 lbs boneless skinless chicken breasts cut into 1-inch pieces
1.5 cups long-grain white rice uncooked
15 oz jarred Alfredo sauce 1 standard jar
2 cups chicken broth low sodium recommended
1 tsp garlic powder
1 tsp Italian seasoning
0.5 tsp salt or to taste
0.25 tsp black pepper
1.5 cups shredded mozzarella cheese
0.5 cup grated Parmesan cheese divided
2 tbsp fresh parsley chopped, for garnish

Instructions

Preheat your oven to 375 degrees F (190 degrees C). Lightly grease a 9x13 inch baking dish with cooking spray or butter.
Add the uncooked rice, chicken broth, Alfredo sauce, garlic powder, Italian seasoning, salt, black pepper, and half of the Parmesan cheese to the prepared baking dish. Stir well until everything is evenly combined.
Nestle the bite-sized chicken pieces into the rice and sauce mixture, pressing them down gently so they are partially submerged in the liquid.
Cover the baking dish very tightly with a double layer of aluminum foil, pressing it firmly around all the edges to seal in the steam. This is essential for cooking the rice properly.
Bake covered for 50 to 55 minutes, until the rice is tender and has absorbed most of the liquid and the chicken is cooked through. Check the rice at the 50-minute mark by carefully lifting the foil.
Remove the foil carefully, watching out for escaping steam. Sprinkle the shredded mozzarella and the remaining Parmesan evenly over the top of the casserole.
Return the dish to the oven uncovered and bake for an additional 10 to 15 minutes, until the cheese is fully melted, bubbly, and beginning to turn golden at the edges.
Remove the casserole from the oven and let it rest for 5 minutes before serving. Garnish with fresh chopped parsley and serve warm directly from the baking dish.

Notes

Do not substitute instant rice or parboiled rice as these will become mushy. Always seal the foil tightly for the covered bake or the rice will not cook through. Leftovers keep in the refrigerator for up to 4 days and reheat best with a splash of chicken broth stirred in. The casserole can be assembled up to 24 hours ahead and refrigerated unbaked. Add 10 to 15 minutes to the covered baking time when cooking straight from the refrigerator.

Ways to Customize

Swap the protein: Rotisserie chicken works beautifully here if you want to cut prep time even further. Shredded leftover turkey or diced ham are also excellent options for using up fridge staples.
Add vegetables: Stir in frozen broccoli florets, baby spinach, or sliced mushrooms before baking to sneak in extra nutrition and turn this into one of those Healthy Casseroles the whole family will actually eat.
Make it spicy: A pinch of red pepper flakes or a spoonful of calabrian chili paste stirred into the sauce adds a gentle kick that balances the richness of the Alfredo.
Go gluten-free: Most jarred Alfredo sauces are naturally gluten-free, but always check the label. This recipe is otherwise already free of any flour or pasta, making it easy to accommodate gluten-free diners.

How to Make Dump & Bake Chicken Alfredo Rice Casserole

Preheat the oven: Set your oven to 375 degrees F and lightly grease a 9×13 inch baking dish with cooking spray or a thin layer of butter so nothing sticks to the sides.
Combine the base: Add the uncooked rice, chicken broth, Alfredo sauce, garlic powder, Italian seasoning, salt, and pepper directly into the prepared baking dish. Stir well to combine everything into an even, saucy mixture.
Add the chicken: Nestle the bite-sized chicken pieces into the rice mixture, pressing them down slightly so they are partially submerged in the liquid. This helps them stay moist as they cook.
Cover tightly: Seal the baking dish completely with a double layer of aluminum foil, pressing it snugly around the edges. This traps the steam and is what cooks the rice from below while keeping the chicken tender.
Bake covered: Place the dish in the preheated oven and bake for 50 to 55 minutes, until the rice is fully cooked and has absorbed most of the liquid.
Add the cheese: Remove the foil carefully, watching out for the steam. Sprinkle shredded mozzarella and grated Parmesan evenly over the top of the casserole.
Bake uncovered: Return the dish to the oven uncovered for 10 to 15 minutes, until the cheese is melted, bubbly, and just starting to turn golden at the edges.
Rest before serving: Allow the Baked Chicken Casserole to rest for 5 minutes before serving. This lets the sauce thicken slightly and makes it much easier to scoop into neat portions.

Expert Tips

Do not skip the foil: The tight seal is non-negotiable for this Chicken Alfredo Bake. Without it, the liquid evaporates too quickly and the rice ends up undercooked and crunchy. Press the foil all the way to the edges.
Check your rice at the 50-minute mark: Ovens vary, and the rice can finish anywhere between 45 and 60 minutes. If it still has a noticeable bite, cover it back up and give it another 5 to 10 minutes before adding the cheese.
Avoid instant or parboiled rice: These varieties cook much faster than regular long-grain white rice and will turn mushy by the time the chicken is fully cooked. Stick with standard long-grain white rice for the best texture.
Cut chicken pieces uniformly: Pieces that are roughly the same size, about 1-inch cubes, will cook at the same rate and prevent some from drying out while others finish cooking.

Serving Suggestions

Garnish with fresh herbs: A handful of chopped fresh parsley or basil scattered over the finished casserole adds a pop of color and a fresh, bright note that cuts through the richness.
Pair with a crisp salad: A simple arugula salad with lemon vinaigrette or a classic Caesar balances the creamy Rice Casserole beautifully and rounds out the meal.
Serve with garlic bread: Crusty garlic bread or soft dinner rolls are perfect for scooping up every last bit of that creamy Alfredo sauce from the dish.
Add a vegetable side: Roasted asparagus, steamed green beans, or sauteed zucchini complement this dish well and add color to the plate.

Make Ahead and Storage

Refrigerating leftovers: Store cooled leftovers in an airtight container or cover the baking dish tightly with plastic wrap. Refrigerate for up to 4 days.
Freezing: This casserole freezes well. Portion it into freezer-safe containers and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
Reheating from the fridge: Add a splash of chicken broth or milk to the portion before reheating to loosen the sauce, then microwave in 60-second intervals, stirring between each, until heated through. You can also reheat it covered in a 350 degree F oven for about 20 minutes.
Make ahead tip: You can assemble the entire unbaked casserole up to 24 hours in advance, cover it tightly, and store it in the refrigerator. Add 10 to 15 extra minutes to the covered baking time since it will be going into the oven cold.

Frequently Asked Questions

Can I use brown rice instead of white rice?
Brown rice requires significantly more liquid and a longer cook time, so it is not a direct swap in this recipe. If you want to use brown rice, increase the broth by half a cup and extend the covered baking time to around 75 to 80 minutes.

Can I use frozen chicken?
It is best to use thawed chicken for this recipe. Frozen chicken releases too much water as it cooks, which can throw off the liquid ratio and leave the rice soupy.

What if my casserole looks too liquidy when I remove the foil?
Do not worry. The casserole will thicken noticeably as it bakes uncovered and then rests. If it still seems loose after resting 5 minutes, it will continue to firm up as it cools slightly on the table.

Can I use homemade Alfredo sauce instead of jarred?
Absolutely. If you have a favorite homemade Alfredo sauce recipe, use about 15 ounces of it in place of the jarred version. Just make sure it is a full-fat, cream-based sauce for the richest results.
