Chicken Rice Casserole Recipe Without Canned Soup: Homemade Creamy Base From Scratch

This chicken rice casserole proves that scratch-made can be just as convenient as shortcuts. A homemade cream sauce replaces canned soup without adding complexity.

The result is a creamy, comforting dish with tender chicken, fluffy rice, and a rich, velvety base that bakes to golden perfection. No processed ingredients required.

Ingredients for Chicken Rice Casserole Recipe Without Canned Soup

Whole food ingredients create this creamy, comforting casserole with no shortcuts needed.

The chicken quality matters here. Boneless, skinless breasts from a trusted butcher or Whole Foods ensure tender results. For the rice, long-grain white absorbs the creamy sauce best—avoid instant varieties. The cheddar should be block cheese you grate yourself (pre-shredded contains anti-caking agents that affect melt). Look for low-sodium chicken broth to control seasoning precisely.

No whole milk? Half-and-half with a splash of water works, but avoid skim—it won’t deliver the same richness. Swap celery for fennel or bell pepper if preferred. For a gluten-free version, rice flour or cornstarch replaces all-purpose (use half the amount). The Dijon can be regular yellow mustard in a pinch, though the flavor profile will be milder.

Assemble the casserole within 2 hours of prepping ingredients to prevent rice from absorbing too much liquid. Leftovers keep 4-5 days refrigerated or 3 months frozen. Reheat covered with foil to maintain moisture.

Step-by-Step Instructions for Chicken Rice Casserole Without Canned Soup

Achieve a velvety, homemade sauce from scratch with this professional, foolproof method.

Step 1: Sauté Aromatics and Cook Chicken

Melt ¼ cup unsalted butter in a large skillet over medium heat. Add the finely diced yellow onion, minced garlic, and finely chopped celery, cooking for 5-6 minutes until softened and fragrant. The onion should turn translucent at the edges without browning.

Push the aromatics to one side and add the diced boneless skinless chicken breast. Cook for 6-8 minutes until the chicken is no longer pink and reaches an internal temperature of 165°F. Season with 1½ teaspoons kosher salt and ½ teaspoon freshly ground black pepper during cooking.

Step 2: Create the Creamy Roux-Based Sauce

Reduce heat to medium-low and add the remaining ¼ cup unsalted butter to the skillet. Once melted, whisk in the ⅓ cup all-purpose flour to form a smooth roux. Cook for 2 minutes, stirring constantly, until the mixture turns a light golden color and smells slightly nutty.

Gradually pour in the 2 cups whole milk and 2 cups chicken broth, whisking continuously to prevent lumps. Increase heat to medium and bring to a gentle simmer, stirring frequently. The sauce should thicken enough to coat the back of a spoon within 5-7 minutes.

Step 3: Incorporate Flavor Enhancers and Rice

Stir in the 1 tablespoon Dijon mustard and 1 teaspoon Worcestershire sauce to the sauce, blending well. These ingredients add depth and umami without overpowering the dish. Taste and adjust seasoning if needed—remember the chicken and broth may already contribute saltiness.

Add the 1.5 cups uncooked long-grain white rice to the skillet, stirring to ensure each grain is coated in the creamy sauce. The rice should appear glossy and well-distributed throughout the mixture. Remove from heat and fold in the 1 cup thawed frozen peas.

Step 4: Bake to Perfection with Cheese Topping

Transfer the chicken and rice mixture to a greased 9×13-inch baking dish, spreading it evenly. Sprinkle the 2 cups shredded cheddar cheese uniformly over the top. The cheese should form a complete layer with no bare spots to ensure a golden, melted finish.

Bake in a preheated 375°F oven for 30-35 minutes until the casserole is bubbling at the edges and the cheese is deep golden brown with some spots of lighter color. The rice should be tender and fully cooked when tested with a fork.

Remove from the oven and let rest for 5-10 minutes before serving. This allows the casserole to set slightly, making it easier to portion while ensuring the sauce doesn’t run out when served.

Dietary Considerations for This Dish

Gluten-Free Version

Replace the ⅓ cup all-purpose flour with ⅓ cup rice flour or ¼ cup cornstarch for a gluten-free roux. I find Bob’s Red Mill rice flour works best without altering the flavor profile. The sauce will thicken similarly but may need an extra minute of cooking. 💪

Dairy-Free Adaptation

Swap whole milk for unsweetened almond milk or oat milk, and use dairy-free cheddar shreds like Violife or Daiya. The sauce may be slightly thinner, so add an extra tablespoon of flour to the roux to compensate.

Lower-Carb Option

Use cauliflower rice instead of long-grain white rice—about 5 cups of fresh or thawed frozen cauliflower rice. Reduce baking time to 20-25 minutes since cauliflower cooks faster. The dish will be lighter but just as flavorful.

Vegetarian Swap

Replace chicken with 1.5 lbs cremini mushrooms, sliced thickly. Sauté them until they release their moisture and turn golden brown. Use vegetable broth instead of chicken broth to keep it fully vegetarian.

Lactose-Free Notes

For lactose intolerance, use lactose-free milk and lactose-free cheddar cheese. Brands like Green Valley Creamery work beautifully. The texture and taste remain identical to the original.

If avoiding dairy entirely, nutritional yeast adds a cheesy flavor to the topping.
