You literally just toss everything into a dish, pop it in the oven, and let the magic happen. No precooking the chicken, no boiling the rice. Now, how’s that for a lifesaver on a busy weeknight?

Why You’ll Love This

First off, it’s a true one-dish wonder. You mix everything right in the baking dish, which means cleanup is an absolute dream. But the best part? This meal is so, so comforting. We’re talking tender chunks of chicken, creamy alfredo sauce, and fluffy rice all baked together into a cohesive, delicious meal. It’s incredibly forgiving, too—perfect for those nights when you’re juggling homework, chores, and a million other things. And honestly, it just tastes like you spent hours in the kitchen, when your secret is safe with me.

Ingredients You’ll Need

• 1 ½ lbs boneless, skinless chicken breasts, cubed: Using pre-cut pieces means no extra work.
• 1 ½ cups uncooked long-grain white rice: The perfect base to absorb all that creamy sauce.
• 1 (15 oz) jar of quality alfredo sauce: The star of the show for that rich, creamy flavor.
• 3 cups chicken broth: Helps cook the rice perfectly and adds a ton of savory depth.
• 1 cup whole milk: Adds extra richness and creaminess to the sauce base.
• 4 cloves garlic, minced: Because what’s an alfredo without that punch of garlic?
• 1 tsp Italian seasoning: A simple blend that brings all the classic herbal notes.
• 1 ½ cups shredded Italian cheese blend (or mozzarella): For that irresistible, gooey, cheesy top.
• Salt and black pepper to taste: To make all those flavors pop.
• Fresh parsley, chopped (optional for garnish): A little green for a pop of color and freshness.

Let’s Get Cooking Step by Step

1. Preheat your oven to 400°F (200°C). Grab a 9×13 inch baking dish – no need to grease it.
2. Now for the fun part: the dump! In the baking dish, combine the uncooked rice, cubed chicken, alfredo sauce, chicken broth, milk, minced garlic, Italian seasoning, and a good pinch of salt and pepper.
3. Stir everything together until it’s well combined and the rice is submerged in the liquid. This ensures every grain cooks up fluffy.
4. Cover the dish tightly with aluminum foil. This traps the steam, which is essential for cooking the rice and chicken through.
5. Bake for 45 minutes. Carefully remove the dish from the oven and take off the foil. Give everything a good stir. The rice should be nearly tender at this point.
6. Sprinkle the shredded cheese evenly over the top. Return the dish to the oven, uncovered, for another 10-15 minutes, or until the cheese is beautifully melted and bubbly and the top is just starting to get golden.
7. Take it out and let it sit for about 5-10 minutes before serving. This lets the sauce thicken up nicely. Garnish with a little fresh parsley if you’re feeling fancy. So good.

Serving Ideas & Pairings

This casserole is a complete meal all on its own, but I love to round it out with a simple side. A crisp green salad with a tangy vinaigrette is the perfect contrast to the rich, creamy alfredo. Some roasted green beans or asparagus would be fantastic, too. And if you’re serving a crowd, a loaf of warm, crusty garlic bread is basically non-negotiable for soaking up every last bit of that delicious sauce. It’s the ultimate cozy dinner for two or a easy family meal.

Variations & Substitutions

This recipe is a wonderful canvas for your own creativity! For a Tuscan twist, stir in a handful of chopped sun-dried tomatoes and a couple big handfuls of fresh spinach when you remove the foil. If you’re out of chicken broth, you can use water with an extra teaspoon of seasoning, but the broth adds so much more flavor. Don’t have an Italian blend? Mozzarella or even a Parmesan-Asiago mix works beautifully. And for a lighter version, try using half-and-half instead of whole milk and a light alfredo sauce.

Storage & Reheating

Let any leftovers cool completely before storing. They’ll keep in an airtight container in the fridge for up to 4 days. To reheat, the microwave is quick and easy—just splash a tablespoon of water or broth over a portion to keep it from drying out, cover it, and heat in 30-second bursts, stirring in between. For a crisper top, reheat it in a 350°F oven in an oven-safe dish until warmed through, about 15-20 minutes. You can also freeze this casserole! Portion it out, freeze for up to 3 months, and thaw in the fridge overnight before reheating.

Pro Tips For Perfect Results

• Don’t skip the foil! Covering the dish for the first part of baking is crucial for the rice to cook properly.
• Use a good quality alfredo sauce from a jar—it really makes a difference in the final flavor.
• Cube your chicken into even, bite-sized pieces so they cook through at the same rate.
• Letting the casserole rest for a few minutes after baking is not just a suggestion. It allows the sauce to set up and makes serving so much easier.
• Give it a good stir when you take the foil off. This helps redistribute the liquid and ensures no rogue grains of rice are left uncooked.
• And remember, all ovens vary, so if your cheese isn’t bubbly and gorgeous at 15 minutes, give it a few more!

Frequently Asked Questions

Can I use a different type of rice? I really recommend sticking with long-grain white rice for the best results and cook time. Brown rice requires more liquid and a longer baking time, which could lead to overcooked chicken.

My casserole came out a little soupy. What happened? This usually means it just needs a few more minutes uncovered in the oven to let some of the liquid evaporate and thicken. Also, letting it rest before serving is key, as the sauce continues to thicken as it cools.

Can I make this alfredo rice casserole ahead of time? You can mix all the ingredients (except the cheese topping) in the baking dish, cover it tightly, and refrigerate for up to 8 hours. You might need to add a few extra minutes to the bake time since it’s going into the oven cold.

What other proteins work in this alfredo chicken and rice recipe? This method is fantastic with cubed smoked turkey or even meatballs! It’s a great way to use up leftover turkey after the holidays for a whole new meal. Truly, this Dump-and-Bake Chicken Alfredo Casserole is my go-to for a reason—it’s reliable, delicious, and frees you up to enjoy your evening instead of slaving over the stove.
