Broccoli Cheddar Chicken and Rice Casserole That's Actually Creamy (Not Gluey) — in 45 Minutes
Creamy, cheesy, and on the table in 45 minutes with rotisserie chicken. This is the weeknight casserole that actually delivers.
Equipment
- Large pot for blanching broccoli
- Medium saucepan
- 9x13 baking dish
- Whisk
- Chef's Knife and Cutting Board
- Large bowl for mixing
Ingredients
- 2 tbsp unsalted butter
- 1/4 cup all-purpose flour
- 2 cups whole milk
- 1 cup low-sodium chicken stock
- 2 cups shredded sharp cheddar (freshly grated)
- 1/2 tsp smoked paprika
- 1/2 tsp garlic powder
- 1/4 tsp cayenne pepper (optional)
- 3 cups fresh broccoli florets
- 2 cups shredded rotisserie chicken
- 2 cups cooked white rice
- to taste salt
- to taste black pepper
- 1/2 cup panko breadcrumbs
- 1 tbsp melted butter (for topping)
Instructions
- Preheat your oven to 375°F. Bring a large pot of salted water to a boil for the broccoli.
- Drop the florets into the boiling water for exactly 90 seconds. Drain and immediately run cold water over them to stop the cooking. Set aside.
- In a medium saucepan over medium heat, melt the butter. Whisk in the flour and cook for 1-2 minutes, stirring constantly, until it smells toasty and looks like wet sand.
- Slowly pour in the milk and chicken stock while whisking constantly to prevent lumps. Bring to a gentle simmer. It will thicken in about 3-4 minutes.
- Remove the pot from the heat. Stir in the shredded cheddar, smoked paprika, garlic powder, cayenne (if using), salt, and pepper. Stir until the cheese is completely melted and the sauce is smooth.
- In a large bowl, gently mix the cooked rice, shredded chicken, blanched broccoli, and the cheese sauce. Transfer to your baking dish.
- Sprinkle the buttered panko breadcrumbs evenly over the top. Bake for 20-25 minutes, until the casserole is bubbly around the edges and the topping is golden brown.
- Let it sit for 5 minutes before scooping. It sets up beautifully and won't be soupy.
Notes
Pro tips: Grate your own cheese – pre-shredded has anti-caking agents that turn the sauce grainy. Don't skip the broccoli blanch – raw broccoli releases water and thins the sauce. Season at every stage – a pinch of salt at each step builds depth. Let the casserole rest 5 minutes before serving – it sets up cleanly.
Storage and reheating: Store in an airtight container in the fridge for up to 4 days. The flavors meld overnight. To freeze, assemble without the panko topping, cover tightly, and freeze for up to 3 months. Thaw overnight in the fridge, add the topping, and bake. Reheat in a 350°F oven for 10 minutes to restore crisp topping. Microwave works in a pinch but breadcrumbs will soften.
Gluten-free option: Use a 1:1 gluten-free all-purpose flour blend in the roux. Whisk a little longer to cook out the raw flour taste.
