Recipe for Broccoli Rice Casserole with Chicken: Ingredients

• 1 1/2 cups uncooked long-grain white rice, or 4 cups cooked rice
• 1 pound (450 g) boneless skinless chicken breast, cut into 3/4-inch pieces
• 1 teaspoon fine salt, divided
• 1/2 teaspoon black pepper, divided
• 1 tablespoon olive oil
• 1 large head broccoli, cut into small florets (about 4 cups)
• 2 tablespoons unsalted butter
• 1 small yellow onion, finely diced
• 3 garlic cloves, minced
• 3 tablespoons all-purpose flour
• 2 cups low-sodium chicken stock
• 1 cup whole milk
• 1 teaspoon Dijon mustard
• 1/2 teaspoon sweet paprika
• 2 cups (200 g) shredded sharp cheddar cheese, divided
• 1/3 cup plain Greek yogurt
• 2 tablespoons chopped parsley, optional

Step-by-Step Instructions

1. Cook the rice and heat the oven

Cook the rice according to the package directions until just tender, then fluff it with a fork. You need 4 cups of cooked rice for the casserole. Heat the oven to 190°C / 375°F. Lightly oil a 9-by-13-inch baking dish or another 3-quart casserole dish.

Cooked, cooled rice is particularly handy here. If you are using leftovers, break up compact clumps with clean fingers or a fork before mixing in the sauce.

2. Blanch the broccoli

Bring a medium pot of water to a boil and salt it lightly. Add the broccoli florets and cook for 2 minutes, until bright green but still firm. Drain immediately and rinse under cold water to stop the cooking. Set the broccoli aside.

Small florets distribute evenly and turn tender in the final bake. Large stems can remain too firm, so peel and thinly slice them or save them for another meal.

3. Brown the chicken

Pat the chicken dry and season it with 1/2 teaspoon salt and 1/4 teaspoon black pepper. Heat the olive oil in a large skillet over medium-high heat. Add the chicken in a single layer and cook for 3 to 4 minutes, stirring once or twice, until it has some golden edges. Transfer it to a plate; it will finish cooking in the oven.

The chicken does not need to be fully cooked yet. Partial cooking helps the pieces stay juicy as they bake in the sauce. Keep the skillet from getting crowded, or the chicken will steam instead of brown.

4. Make the creamy cheese sauce

Reduce the heat to medium. Melt the butter in the same skillet, then add the onion with the remaining salt and pepper. Cook for 4 to 5 minutes until softened. Stir in the garlic for 30 seconds. Sprinkle the flour over the vegetables and stir continuously for 1 minute to remove the raw flour taste.

Slowly whisk in the chicken stock and milk. Add the Dijon mustard and paprika. Simmer for 3 to 5 minutes, whisking often, until the sauce is smooth and thick enough to coat a spoon. Remove the skillet from the heat and stir in 1 1/2 cups of cheddar until melted. Stir in the Greek yogurt until smooth.

5. Assemble and bake

Fold the cooked rice, browned chicken, and blanched broccoli into the sauce. Scrape everything into the prepared baking dish and level the surface. Scatter the remaining 1/2 cup cheddar over the top.

Bake uncovered for 22 to 26 minutes, until the edges are bubbling and the thickest chicken pieces reach 74°C / 165°F on an instant-read thermometer. Rest the casserole for 5 minutes before serving so the sauce settles. Finish with parsley, if using.

Tips for Best Results

Keep the rice fluffy

Very soft rice can make the finished casserole dense. Cook it only until tender, or use day-old rice that has been chilled and separated. Long-grain white rice gives the lightest texture, though fully cooked brown rice works too.

Grate the cheese yourself

Pre-shredded cheese is convenient, but its anti-caking agents can make a sauce slightly grainy. Sharp cheddar grated from a block melts more smoothly and gives the broccoli rice casserole with chicken a richer finish.

Check the chicken, not the clock

Ovens and casserole dishes vary, so start checking near the lower end of the baking time. Use a thermometer in several chicken pieces. Poultry is safe at 74°C / 165°F.

Ingredient Substitutions

• Use boneless skinless chicken thighs in place of breast; cut them into bite-size pieces and cook to the same safe temperature.
• Replace cheddar with Monterey Jack, mild cheddar, or a mix of cheddar and mozzarella.
• Use frozen broccoli florets when fresh broccoli is unavailable. Thaw, pat dry, and skip the blanching step.
• Substitute cooked brown rice for white rice for a nuttier flavor and more chew.
• For a little heat, add a pinch of cayenne or crushed red pepper with the paprika.

What to Serve With

This creamy casserole is especially good with a light, crunchy side. Try a green salad with lemon dressing, roasted carrots, or cucumber and tomato salad. For another easy chicken dinner later in the week, browse our chicken recipes or make these oven baked chicken thighs.

Storage Instructions

Cool leftovers promptly and transfer them to airtight containers within 2 hours of baking. Refrigerate for up to 3 days. For longer storage, portion the cooled casserole into freezer-safe containers and freeze for up to 2 months.

Move frozen portions to the refrigerator overnight to thaw. Do not leave chicken casserole at room temperature to thaw. Shallow portions cool and reheat more evenly.

Reheating Instructions

Reheat individual portions in the microwave, loosely covered, in 60-second intervals until hot throughout. Add a tablespoon of milk or chicken stock before heating if the rice looks dry.

For a larger portion, place the casserole in an oven-safe dish, cover with foil, and bake at 175°C / 350°F for 20 to 25 minutes. Reheat leftovers until the center reaches 74°C / 165°F. Add the cheese topping for the final few minutes if you like a freshly melted finish.

Frequently Asked Questions

Can I assemble this casserole ahead of time?

Yes. Assemble the mixture in the baking dish, cover, and refrigerate for up to 24 hours. Let the dish stand at room temperature for about 20 minutes while the oven heats, then bake. Because it starts cold, it may need a few extra minutes; verify that the chicken reaches 74°C / 165°F.

Can I use rotisserie-style cooked chicken?

Yes. Fold 3 cups of cooked, shredded chicken into the sauce with the rice and broccoli, then bake until hot and bubbling. Since the chicken is already cooked, you only need to heat the casserole through; use a thermometer to confirm the center reaches 74°C / 165°F when reheating.

Why is my casserole dry?

Dry casserole usually means the rice absorbed more sauce than expected or the dish baked too long. Measure the cooked rice, use the full amount of sauce, and take the casserole out as soon as the chicken is safely cooked. A splash of warm stock helps restore leftovers.

Can I make it without broccoli?

Certainly. Swap in blanched cauliflower, cooked peas, or sautéed mushrooms. Keep the vegetable pieces small and remove excess moisture so the sauce remains creamy.

Conclusion

This recipe for broccoli rice casserole with chicken brings creamy comfort, tender chicken, and a satisfying vegetable together in one baking dish. Cooked rice, a quick cheese sauce, and a reliable temperature check keep it simple enough for a weeknight. Save the leftovers for tomorrow’s lunch or keep it in your regular dinner rotation for an easy, crowd-pleasing meal.
