Simple to prepare yet impressive to serve, this casserole is ideal for family dinners or potlucks. Here’s how to make it perfectly every time.

Ingredients for Chicken and Rice Casserole Recipe with Mayonnaise

Tender chicken, fluffy rice, and a velvety mayonnaise sauce create pure baked comfort in every bite.

The chicken quality is paramount here. Boneless, skinless breasts from Whole Foods or Costco ensure tenderness without chewiness. For the rice, long-grain white varieties like jasmine or basmati resist mushiness better than instant. The mayonnaise should be full-fat—Hellmann’s or Duke’s provide the richest base for that signature creamy texture that defines this dish.

No cream of chicken soup? Cream of mushroom works as a direct substitute, or make a roux with butter, flour, and broth for a from-scratch version. Fresh vegetables can replace the frozen mix—just use 1 cup total of diced carrots, peas, or bell peppers. For extra richness, swap half the cheddar for Gruyère, which melts beautifully and adds depth.

Assemble and refrigerate up to 24 hours before baking for make-ahead convenience. Leftovers keep 4-5 days in the fridge or freeze for 3 months. Reheat covered with foil to prevent the top from over-browning during warming.

Step-by-Step Instructions for Chicken and Rice Casserole With Mayonnaise

This method ensures a creamy texture and perfectly cooked rice with a golden, bubbly top.

Step 1: Sauté Aromatics and Cook the Chicken

Heat a large skillet over medium heat and melt the 2 tbsp unsalted butter. Add the finely diced yellow onion and chopped celery stalks, cooking for 4-5 minutes until they soften and become translucent. Stir in the minced garlic cloves and cook for 30 seconds until fragrant.

Add the 1.5 lb boneless skinless chicken breasts, cut into bite-sized pieces, along with 1 tsp kosher salt, 0.5 tsp ground black pepper, and 0.5 tsp dried thyme. Cook for 6-8 minutes, stirring occasionally, until the chicken is no longer pink and is cooked through. This builds a flavor foundation for the casserole.

Step 2: Prepare the Rice and Combine Ingredients

In a large mixing bowl, combine the 1.5 cups long-grain white rice (rinsed thoroughly), 1 can cream of chicken soup, 2.5 cups chicken broth, and 0.25 cup all-purpose flour. Whisk until the mixture is smooth and the rice is fully coated. This ensures the rice will cook evenly in the oven.

Add the cooked chicken, sautéed vegetables, 1 cup frozen peas and carrots (thawed and drained), and 1.5 cups mayonnaise to the rice mixture. Stir until everything is well combined and the rice is evenly distributed. The mayonnaise adds richness and creaminess to the dish.

Step 3: Assemble and Bake the Casserole

Transfer the mixture to a greased 9×13-inch baking dish and spread it evenly. Sprinkle the 1.5 cups shredded cheddar cheese over the top, ensuring full coverage for that golden, bubbly finish. This layer will melt into a delicious, cheesy crust.

Bake in a preheated 375°F oven for 45-50 minutes, or until the casserole is bubbling around the edges and the top is golden brown. If the top begins to darken too quickly, tent the dish with foil for the remaining baking time. This ensures the casserole cooks through without burning.

Step 4: Rest and Serve

Remove the casserole from the oven and let it rest for 10 minutes before serving. This allows the rice to absorb any remaining liquid and the cheese to set slightly, making it easier to serve.

Scoop portions onto plates, ensuring each serving includes a mix of chicken, rice, and vegetables. The casserole should be creamy with a well-browned top and tender chicken throughout. Serve warm for the best texture and flavor.

Common Mistakes When Making This Recipe

Overmixing the Rice

Stirring the rice too vigorously after combining all ingredients can break the grains, leading to a mushy texture. I gently fold everything together just until the rice is evenly coated with the creamy mixture. This keeps the grains intact for that perfect bite. 💡

Skipping the Rinse

Unrinsed rice releases excess starch, which can make your casserole gummy. I always rinse my 1.5 cups long-grain white rice under cold water until the water runs clear. This simple step ensures fluffy, separate grains in the final dish.

Undercooking the Chicken

Adding raw chicken to the casserole risks uneven cooking. I always sear the 1.5 lb chicken breasts first until no longer pink, about 6-8 minutes. This builds flavor and guarantees the chicken is perfectly cooked when the casserole comes out of the oven.

Using Low-Fat Mayo

The recipe needs full-fat mayonnaise for its signature creaminess. I’ve tried light versions, and the texture suffers. Stick with Hellmann’s or Duke’s—they provide the rich base this dish deserves.

Overbaking the Top

That golden crust can turn burnt if left too long. I check at 45 minutes and tent with foil if it’s browning too quickly. The casserole is done when bubbling at the edges and the center reaches 165°F. 🔥

Skipping the Rest

Cutting too soon lets the juices escape, making the casserole runny. I always wait the full 10 minutes after baking. This gives the rice time to absorb the last bit of liquid and the cheese a chance to set.
