The chicken is the star here. Boneless, skinless breasts stay juicy when cubed small—avoid pre-cut strips (they dry out). Costco has great bulk packs, but any supermarket carry works fine. For the rice, long-grain white gives that fluffy texture (jasmine or basmati work too). The cheddar? Block cheese grated fresh melts better than pre-shredded (those anti-caking agents are the enemy of smooth sauce).

No cream of chicken soup? Cream of mushroom works in a pinch, or mix 1 cup milk + 3 tbsp cornstarch for a quick substitute. Broccoli can be fresh or frozen (thaw and drain first). Swapping rice? Brown rice needs more liquid, so add an extra half cup broth. Sour cream sub? Greek yogurt at 1:1 ratio, but full-fat is key—low-fat gets watery.

Assemble and bake right away, or prep ahead and refrigerate for 24 hours before baking. Leftovers keep 4-5 days in the fridge, reheat covered. Freezes beautifully for 3 months—portion before freezing for easy meals.

Step-by-Step Instructions for Broccoli Rice Casserole with Chicken

Easier than it looks and ready in under an hour with this method.

Step 1: Cook the Rice and Chicken

Start by cooking the 1.5 cups long-grain white rice according to package directions, but use chicken broth instead of water for extra flavor. While the rice cooks, cut the 1.5 lb boneless chicken breast into bite-sized pieces and season with 1 tsp salt and 0.5 tsp black pepper.

Heat a large skillet over medium-high heat and cook the chicken until lightly browned and cooked through, about 6-8 minutes. Remove from heat and set aside. Preheat your oven to 375°F so it’s ready when you need it.

Step 2: Prepare the Creamy Sauce Base

In a large saucepan, melt the 0.5 cup unsalted butter over medium heat. Add the finely diced yellow onion and cook for 3-4 minutes until soft and translucent. Stir in the minced garlic cloves and cook for 30 seconds until fragrant.

Whisk in the 0.5 cup all-purpose flour to create a roux. Cook for 1 minute, stirring constantly, to remove the raw flour taste. Slowly pour in the 1 cup whole milk and 1 can cream of chicken soup, whisking continuously until the mixture is smooth and begins to thicken.

Step 3: Combine All Ingredients

Stir in the 1 cup sour cream and 1 tbsp Dijon mustard until fully incorporated. Fold in the cooked rice, chicken, and 3 cups fresh broccoli florets (cut into small pieces) until everything is evenly coated in the sauce.

Here’s the thing—this is where the magic happens. The sauce should be creamy but not runny. If it seems too thick, add a splash of milk to loosen it up. Transfer the mixture to a greased 9×13-inch baking dish.

Step 4: Top with Cheese and Bake

Sprinkle the 2 cups shredded cheddar cheese evenly over the top of the casserole. Bake in the preheated oven for 20-25 minutes until the cheese is melted and golden brown and the edges are bubbling.

Real talk: don’t skimp on the baking time. You want that cheese to form a beautiful, slightly crispy layer on top. Let the casserole rest for 5 minutes after removing it from the oven before serving—this allows everything to set and makes it easier to portion out.

Storing and Reheating This recipe for broccoli rice casserole with chicken

Refrigerator Storage

Let the casserole cool for no more than 2 hours before transferring to airtight containers. I use glass containers with locking lids to keep everything fresh. Store in the fridge for up to 4-5 days at 40°F or below. ❄️

Freezer Storage

This dish freezes beautifully for up to 3 months. Portion into individual servings in freezer-safe containers or heavy-duty freezer bags. Leave ½ inch of headspace to prevent expansion, and squeeze out excess air to avoid freezer burn.

Oven Reheating

Preheat your oven to 350°F and place the casserole in an oven-safe dish. Cover with aluminum foil and bake for 20-25 minutes, or until the internal temperature reaches 165°F. Add a splash of milk if it seems dry.

Microwave Reheating

For quick meals, microwave individual portions covered with a damp paper towel. Heat on 70% power for 2-3 minutes, stir, then continue in 30-second intervals until heated through. This prevents the cheese from separating.

Make-Ahead Tip

Assemble the casserole completely, cover tightly, and refrigerate for up to 24 hours before baking. This actually enhances the flavors as the ingredients meld together. Just add 5-10 minutes to the baking time if starting cold. 💡
