Ingredients Method

Ingredients

  

• 1.5 pounds boneless, skinless chicken breasts, cut into 1-inch pieces
• 4 cups broccoli florets (fresh or frozen, thawed)
• 1 tablespoon olive oil
• 1 small yellow onion, finely diced
• 3 cloves garlic, minced
• 2 tablespoons butter
• 2 tablespoons all-purpose flour
• 1 cup low-sodium chicken broth
• 1 cup milk (whole or 2%)
• 1 teaspoon Dijon mustard (optional but recommended)
• 1/2 teaspoon smoked paprika (or regular paprika)
• 1/2 teaspoon salt, plus more to taste
• 1/4 teaspoon black pepper
• 2 cups shredded cheddar cheese, divided
• 1/2 cup grated Parmesan cheese
• 1/2 cup sour cream or plain Greek yogurt
• 1 cup cooked rice or small pasta (optional, for a heartier bake)
• Nonstick spray or butter for greasing the baking dish

Method

 

1. Preheat and prep: Heat the oven to 375°F (190°C). Grease a 9x13-inch baking dish with nonstick spray or butter.
2. Par-cook the broccoli: Steam fresh florets for 2–3 minutes until bright green and just tender. If using thawed frozen broccoli, pat it dry well. This prevents a watery bake.
3. Cook the chicken: Season chicken pieces lightly with salt and pepper. Heat olive oil in a large skillet over medium-high. Sear chicken for 4–5 minutes, stirring occasionally, until just cooked through. Transfer to a plate.
4. Sauté aromatics: In the same skillet, reduce heat to medium. Add butter and the diced onion. Cook 3–4 minutes until softened. Stir in garlic and cook 30 seconds until fragrant.
5. Make the sauce: Sprinkle flour over the onion mixture and stir for 1 minute. Slowly whisk in chicken broth until smooth, then add milk. Stir in Dijon, paprika, salt, and pepper. Simmer 2–3 minutes until slightly thickened.
6. Add the cheeses: Remove skillet from heat. Stir in 1.5 cups cheddar and all the Parmesan until melted. Fold in sour cream or Greek yogurt. Taste and adjust seasoning.
7. Combine the bake: In a large bowl, mix the chicken, broccoli, and optional rice or pasta. Pour the cheese sauce over and toss to coat evenly.
8. Assemble: Transfer mixture to the prepared baking dish. Smooth the top and sprinkle with the remaining 1/2 cup cheddar.
9. Bake: Bake uncovered for 18–22 minutes, until the edges bubble and the top is golden in spots.
10. Rest and serve: Let it rest 5 minutes to set. Serve warm with a side salad or crusty bread.

Why This Recipe Works

Save

This bake nails the texture balance: juicy chicken, crisp-tender broccoli, and a melty cheese topping that brings it all together. A quick, creamy sauce keeps everything moist without turning soupy.

Using pre-cooked or quickly seared chicken speeds things up and prevents overcooking. Broccoli is lightly pre-steamed so it stays vibrant and doesn’t water down the dish. The result is a family-friendly, make-ahead meal that reheats beautifully.

Ingredients

• 1.5 pounds boneless, skinless chicken breasts, cut into 1-inch pieces
• 4 cups broccoli florets (fresh or frozen, thawed)
• 1 tablespoon olive oil
• 1 small yellow onion, finely diced
• 3 cloves garlic, minced
• 2 tablespoons butter
• 2 tablespoons all-purpose flour
• 1 cup low-sodium chicken broth
• 1 cup milk (whole or 2%)
• 1 teaspoon Dijon mustard (optional but recommended)
• 1/2 teaspoon smoked paprika (or regular paprika)
• 1/2 teaspoon salt, plus more to taste
• 1/4 teaspoon black pepper
• 2 cups shredded cheddar cheese, divided
• 1/2 cup grated Parmesan cheese
• 1/2 cup sour cream or plain Greek yogurt
• 1 cup cooked rice or small pasta (optional, for a heartier bake)
• Nonstick spray or butter for greasing the baking dish

Keeping It Fresh

Store leftovers in an airtight container in the fridge for up to 4 days.

Reheat in the oven at 325°F (165°C) for 15–20 minutes, or microwave in short bursts, stirring halfway. If it looks a bit dry, splash in a tablespoon of milk before reheating. For freezing, cool completely, wrap tightly, and freeze up to 2 months.

Thaw overnight in the fridge, then reheat covered until hot.

Benefits of This Recipe

• Balanced and filling: Protein from chicken, fiber and vitamins from broccoli, and calcium from cheese.
• Family-friendly: Mild flavors, creamy texture, and a cheesy top that wins over picky eaters.
• Flexible: Works with rice, pasta, or low-carb without either. Easy to swap cheeses and veggies.
• Great for meal prep: Assembles ahead and reheats well for busy nights.
• Budget-conscious: Uses simple pantry items and a short ingredient list.

Common Mistakes to Avoid

• Skipping broccoli prep: Raw or wet broccoli releases water and makes the bake soupy. Par-cook and pat dry.
• Overcooking the chicken: It goes into the oven again, so just cook it through on the stove—no more.
• Thin sauce: Let the flour-butter mixture cook a minute and simmer the sauce briefly so it thickens before adding cheese.
• Using pre-shredded cheese only: Bagged shreds can be coated with anti-caking agents.

  For best melt, use at least some freshly grated cheese.

• Overbaking: Too long in the oven can dry it out. Pull it as soon as it’s bubbling with some golden spots on top.

Variations You Can Try

• Ranch twist: Add 1 tablespoon ranch seasoning to the sauce and use a cheddar–Monterey Jack blend.
• Bacon upgrade: Stir in 1/2 cup crisp, crumbled bacon before baking for smoky richness.
• Whole-grain boost: Swap in cooked brown rice or whole-wheat pasta.
• Spicy kick: Add a pinch of red pepper flakes or a diced jalapeño to the onions and garlic.
• Lightened-up: Use 1% milk and Greek yogurt, and reduce cheese by 1/2 cup. Still creamy, just lighter.
• Different veggies: Mix in peas, cauliflower, or sautéed mushrooms.

  Aim for about 4 cups total veggies.

• Gluten-free: Use a 1:1 gluten-free flour blend for the roux, and check that your broth and mustard are gluten-free.

FAQ

Can I use rotisserie chicken?

Yes. Shred about 3 cups of rotisserie chicken and skip the stovetop sear. Add it when combining with the broccoli and sauce.

Do I have to pre-cook the broccoli?

It’s best to steam or blanch it briefly.

This keeps it bright and prevents excess water from thinning your sauce.

What cheeses work best?

Sharp cheddar is classic for flavor and melt. You can blend in mozzarella for stretch or Gruyère for nuttiness. Parmesan adds a salty, savory finish.

Can I make it ahead?

Assemble the casserole up to a day in advance, cover, and refrigerate.

Bake straight from the fridge, adding 5–10 extra minutes if needed.

How can I make it lower carb?

Skip the rice or pasta and stick with chicken and broccoli. You can also reduce the flour to 1 tablespoon and simmer the sauce a bit longer to thicken.

What if my sauce is lumpy?

Whisk vigorously as you add the broth and milk slowly. If lumps persist, strain the sauce or blend it carefully before adding the cheese.

Can I freeze it unbaked?

Yes.

Assemble in a freezer-safe dish, wrap well, and freeze. Thaw overnight, then bake as directed. Add 5–10 minutes if it’s still slightly chilled.
