Servings 6 servings

Ingredients

  

• 3 cups cooked chicken, shredded or cubed (rotisserie works great)
• 4 cups broccoli florets (fresh or frozen; bite-sized)
• 1 small onion, finely chopped (optional but adds flavor)
• 2 cloves garlic, minced
• 2 tablespoons butter
• 2 tablespoons all-purpose flour
• 1 cup chicken broth (low-sodium if possible)
• 1 cup milk (whole or 2% for best creaminess)
• 1/2 teaspoon kosher salt, plus more to taste
• 1/2 teaspoon black pepper
• 1/2 teaspoon onion powder (optional)
• 1/2 teaspoon paprika (optional, for color and flavor)
• 1 1/2 cups shredded cheddar cheese, divided
• 1/2 cup shredded mozzarella or Monterey Jack (optional for extra melt)
• 1/2 cup sour cream or plain Greek yogurt (adds tang and creaminess)
• 1/2 cup panko or regular breadcrumbs (for topping)
• 1 tablespoon olive oil or melted butter (to toss with breadcrumbs)
• Cooking spray or a little butter for greasing the dish

Instructions

 

• Prep the oven and dish: Preheat the oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with cooking spray or butter.
• Par-cook the broccoli: If using fresh broccoli, steam or microwave for 2–3 minutes until just tender-crisp. If using frozen, thaw and pat dry. You want the broccoli to be bright and not watery.
• Sauté aromatics: In a medium saucepan, melt the butter over medium heat. Add onion and cook 3–4 minutes until softened. Stir in garlic and cook 30 seconds until fragrant.
• Make the sauce: Sprinkle in flour and whisk for 1 minute to form a roux. Slowly add chicken broth and whisk until smooth, then add milk. Simmer 3–5 minutes, stirring, until slightly thickened.
• Season and enrich: Stir in salt, pepper, onion powder, and paprika. Off the heat, add 1 cup cheddar and the mozzarella/Jack (if using). Stir until melted and smooth, then fold in sour cream or yogurt.
• Combine in the dish: Add the cooked chicken and broccoli to the baking dish. Pour the cheese sauce over and gently mix to coat everything evenly.
• Add the topping: In a small bowl, combine breadcrumbs with olive oil or melted butter. Sprinkle the remaining 1/2 cup cheddar over the casserole, then the breadcrumb mixture on top.
• Bake: Place in the oven and bake 20–25 minutes until bubbly around the edges and the top is golden.
• Rest and serve: Let it rest 5–10 minutes to set slightly. Serve warm as-is or with rice, buttered noodles, or crusty bread.

How to Store

• Refrigerate: Cool completely, then cover tightly. Keeps 3–4 days in the fridge.
• Reheat: Warm single servings in the microwave in 60–90 second bursts, stirring halfway.

  For a full pan, cover with foil and bake at 350°F until heated through, about 15–20 minutes.

• Freeze: Assemble but don’t bake, or freeze leftovers. Wrap well and freeze up to 2 months. Thaw in the fridge overnight and bake at 350°F until hot and bubbly.

Benefits of This Recipe

• Nutritious comfort: Offers protein, fiber, and calcium alongside a cozy, cheesy texture.
• Budget-friendly: Uses simple, affordable ingredients and stretches leftovers well.
• Time-saving: Rotisserie chicken and frozen broccoli keep prep quick.
• Family-approved: Familiar flavors make it an easy weeknight win.
• Versatile base: Swaps easily for different diets and preferences.

Pitfalls to Watch Out For

• Watery casserole: Wet broccoli or frozen chicken can dilute the sauce.

  Pat dry and par-cook broccoli briefly.

• Gritty sauce: Add liquids slowly to the roux and whisk well to avoid lumps. Don’t boil hard once dairy is added.
• Overbaking: Too long in the oven can dry out the chicken and split the sauce. Pull it when bubbly and golden.
• Under-seasoning: Taste the sauce before assembling.

  Cheese is salty, but you still need a balanced seasoning.

• Soggy topping: Toss breadcrumbs with fat and bake uncovered for a crisp finish.

Recipe Variations

• Rice or pasta bake: Stir in 2 cups cooked rice or 8 ounces cooked pasta for a heartier casserole. Increase sauce by 25% to keep it creamy.
• Bacon ranch twist: Add 1/3 cup cooked, crumbled bacon and 1–2 teaspoons ranch seasoning to the sauce.
• Healthier swap: Use Greek yogurt instead of sour cream and part-skim cheese. Add extra veggies like peas or cauliflower.
• Spicy kick: Stir in 1–2 teaspoons hot sauce or a pinch of red pepper flakes.

  Pepper jack cheese works well too.

• Gluten-free: Use a gluten-free flour blend for the roux and gluten-free breadcrumbs—or skip the crumb topping.
• Keto-friendly: Omit the flour and thicken the sauce with 2–3 ounces cream cheese; skip breadcrumbs.
• Dairy-free: Use a plant-based butter, unsweetened non-dairy milk, and a good melting dairy-free cheese. Thicken with a cornstarch slurry if needed.

FAQ

Can I use raw chicken instead of cooked?

Yes, but it needs to be cooked before baking with the sauce. Cube or shred chicken after sautéing it in a skillet with salt and pepper until fully cooked, then proceed with the recipe.

Using pre-cooked chicken keeps the bake tender and prevents overcooking.

Do I have to pre-cook the broccoli?

A quick steam or microwave helps avoid excess moisture and keeps the texture crisp-tender. If you skip this step, the broccoli may release water and make the casserole runny.

What cheese works best?

Sharp cheddar brings classic flavor, and a bit of mozzarella or Monterey Jack adds stretch. Gruyère, Colby, or a cheddar blend also work well.

Freshly shredded cheese melts more smoothly than pre-shredded.

Can I make it ahead?

Yes. Assemble the casserole, cover, and refrigerate up to 24 hours. Add the breadcrumb topping just before baking.

You may need an extra 5–10 minutes in the oven if starting cold.

How can I lighten the recipe without losing flavor?

Use 2% milk, Greek yogurt instead of sour cream, and reduce cheese by 25% while keeping a sharp variety for stronger flavor. Load up with extra broccoli and season the sauce well.

What can I serve with it?

A simple green salad, roasted carrots, or garlic bread are great sides. If you want more carbs, serve over rice or egg noodles.
