Ingredients
- 3 cups cooked rice (white, brown, or a blend)
- 3 cups cooked, shredded chicken (use halal chicken)
- 3 cups broccoli florets, lightly steamed
- 2 cups shredded cheddar cheese
- 1 small onion, finely diced
- 2 cloves garlic, minced
- 1 1/2 cups milk (dairy or unsweetened plant milk)
- 1 cup low-sodium chicken stock
- 3 tbsp butter or neutral oil
- 3 tbsp all-purpose flour (or gluten-free flour for a GF version)
- 1 tsp Dijon mustard
- 1/2 tsp dried thyme
- Salt and pepper to taste
- 1/2 cup panko breadcrumbs or crushed crackers (optional topping)
- 2 tbsp grated Parmesan (optional)
Step-by-step instructions
- Preheat and prep: Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
- Cook the base: In a medium saucepan, melt butter over medium heat. Sauté diced onion until translucent (3–4 minutes), add garlic and cook 30 seconds.
- Make the sauce: Stir in flour to form a roux and cook 1 minute. Slowly whisk in milk and chicken stock until smooth. Add Dijon, thyme, salt, and pepper. Simmer until slightly thickened, about 3–4 minutes.
- Combine ingredients: In a large bowl, mix cooked rice, shredded chicken, steamed broccoli, and 1 1/2 cups shredded cheddar. Pour the warm sauce over the mix and stir until evenly coated.
- Assemble casserole: Transfer the mixture to the prepared dish and spread evenly. Sprinkle remaining cheddar on top. If using, mix panko with Parmesan and a drizzle of olive oil, then sprinkle over the cheese for a crisp topping.
- Bake: Bake for 20–25 minutes until bubbly and golden on top. Let rest 5–10 minutes before serving.
Tips for success
- Use day-old rice if possible; it holds up better and prevents a mushy casserole.
- Don’t overcook the broccoli—slightly underdone before baking keeps it bright and tender.
- Taste the sauce before mixing with rice; you can adjust salt, pepper, or a splash more Dijon if it needs more depth.
- For even melting, shred your own cheese instead of using pre-shredded varieties that may contain anti-caking agents.
- If you prefer a lighter casserole, swap half the cheddar for a milder melting cheese like Monterey Jack.
Possible variations
- Gluten-free: Substitute gluten-free flour for the roux and use gluten-free breadcrumbs to top.
- Streusel or savory crumble topping: Combine 1/2 cup panko or gluten-free crumbs, 2 tbsp melted butter, 1/4 cup grated Parmesan, and 1 tsp dried herbs; sprinkle over the casserole for added crunch.
- Creamy mushroom twist: Sauté 1 cup sliced mushrooms with the onions and stir into the sauce for earthy depth.
- One-pot comfort: For a quick weeknight version, assemble in a large oven-safe skillet and bake—fewer dishes to wash.
Serving suggestions
Serve this Chicken Broccoli Rice Casserole with a crisp green salad and roasted autumn vegetables for a cozy, seasonal meal. It pairs beautifully with a tart-sweet cranberry relish or pickled red onions to cut through the richness.
Storage recommendations
- Refrigerator: Cool completely, cover tightly, and refrigerate for up to 4 days.
- Freezer: Assemble but don’t bake, then tightly wrap or frost with an airtight lid and freeze for up to 3 months. Thaw overnight in the fridge and bake as directed, adding a few extra minutes if still cold.
- Reheating: Reheat individual portions in the microwave or a covered dish in a 350°F oven until warmed through. Add a splash of milk if the casserole seems dry.
