3 cups broccoli florets (fresh or frozen) If frozen, thaw and pat dry to avoid excess water.

1 ½ cups shredded sharp cheddar cheese Grated for quick melting; reserve ¼ cup for topping.

1 cup shredded mozzarella cheese Adds stretch and mild flavor; can replace with Monterey Jack.

3 Tbsp all‑purpose flour Creates a roux; use cornstarch for gluten‑free.

1 cup whole‑milk milk Full‑fat gives the sauce body; low‑fat works but be gentler on heat.

½ cup chicken broth Boosts umami; can replace with vegetable broth.

1 tsp garlic powder Adds depth without extra moisture.

½ tsp smoked paprika Adds subtle warmth; optional for a milder profile.

Salt and freshly ground black pepper Season to taste throughout the cooking process.

Instructions

Prepare the Chicken & Broccoli

Cut chicken into bite‑size cubes, season lightly with salt and pepper. Steam or blanch broccoli until just tender (≈3 minutes); set aside to dry. This prevents soggy layers later.

Pro Tip: Pat the broccoli with a kitchen towel to remove excess moisture.

Make the Cheese Roux

In a large saucepan melt 2 Tbsp butter over medium heat. Whisk in flour, cooking 1‑2 minutes until golden. Gradually stir in milk and broth, whisking constantly to avoid lumps. Simmer 3‑4 minutes until thickened.

Pro Tip: Keep the heat moderate; high heat can cause the sauce to scorch.

Combine Cheese and Seasonings

Reduce heat to low; stir in garlic powder, smoked paprika, and half of the cheddar and all mozzarella. Mix until fully melted and smooth. Adjust salt and pepper, then remove from heat.

Pro Tip: Adding cheese off‑heat prevents it from becoming grainy.

Assemble the Casserole

In a greased 9‑x‑13 in baking dish, spread the chicken cubes evenly, then the broccoli. Pour the cheese sauce over the top, smoothing with a spatula. Sprinkle remaining cheddar evenly for a golden crust.

Pro Tip: A light drizzle of olive oil on the cheese topping encourages browning.

Bake to Perfection

Bake in a pre‑heated 375°F (190°C) oven for 25‑30 minutes, or until the casserole is bubbling and the cheese topping is golden‑brown. Let rest 5 minutes before serving.

Pro Tip: Resting allows the sauce to set, making slices cleaner.

Expert Tips

Tip #1: Pre‑Cook Chicken

Sear the chicken cubes quickly in a hot pan before adding them to the casserole. This locks in juices and adds a subtle caramelized flavor.

Tip #2: Use Fresh Herbs

A sprinkle of chopped parsley or chives just before serving brightens the dish and adds a fresh contrast to the rich cheese.

Tip #3: Add a Crunch

Top the casserole with a handful of panko breadcrumbs mixed with melted butter for an extra golden, crunchy layer.

Tip #4: Freeze & Reheat

Cool completely, then wrap portions individually. Reheat covered at 350°F for 20‑25 minutes; uncover for the last 5 minutes to restore crispness.

Storage & Variations

Store leftovers in an airtight container in the refrigerator for up to 4 days; reheat gently in the oven or microwave, adding a splash of milk to revive creaminess. For a low‑carb version, replace the flour with almond flour and omit the breadcrumb topping. Swap broccoli for cauliflower or a mix of winter vegetables for seasonal variety.

Frequently Asked Questions

Yes. Thaw the frozen florets, then pat them dry. This prevents excess water from making the casserole soggy while still delivering the same flavor.

Substitute the all‑purpose flour with an equal amount of cornstarch or a gluten‑free flour blend. The sauce will thicken just as well.

Absolutely. Cauliflower, carrots, or a mix of winter squash work well. Keep the total vegetable volume similar to maintain the casserole’s balance.

Use a mix of Gruyère, Fontina, or a sharp white cheddar for a richer flavor profile. Just keep the total cheese amount the same.
