How to Make Cheesy Chicken and Broccoli Bake

Now that you have your ingredients ready, let’s dive into the steps for making this delightful Cheesy Chicken and Broccoli Bake. It’s as easy as pie, and I promise you’ll feel like a culinary superstar!

Step 1: Preheat and Prepare
Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish with butter or non-stick cooking spray.

Step 2: Cook the Chicken and Broccoli
In a large skillet, heat the olive oil over medium-high heat. Season the cubed chicken with garlic powder, onion powder, paprika, salt, and pepper. Add to the hot skillet and cook for 5-6 minutes, until seared on all sides and mostly cooked through. (It will finish cooking in the oven). In the last 2 minutes of cooking, add the fresh broccoli florets to the skillet to slightly tenderize them. If using frozen broccoli, there’s no need to thaw; it will cook perfectly in the sauce. Transfer the chicken and broccoli to the prepared baking dish.

Step 3: Create the Roux for the Sauce
In the same skillet, melt the 3 tablespoons of butter over medium heat. Once melted and bubbling, sprinkle the 3 tablespoons of flour over the butter. Whisk continuously and cook for 1-2 minutes until the mixture (the roux) is a light golden color and smells nutty.

Step 4: Build the Creamy Sauce Base
Gradually pour in the milk and chicken broth while whisking constantly. This prevents lumps from forming. Continue to whisk until the sauce begins to thicken and simmer, about 3-5 minutes.

Step 5: Incorporate the Cheese
Reduce the heat to low. Stir in 1 ½ cups of the shredded cheddar cheese and the ½ cup of Parmesan cheese, along with the dry mustard and nutmeg if using. Whisk until the cheese is completely melted and the sauce is smooth and velvety. Taste and adjust seasoning with salt and pepper.

Step 6: Combine and Assemble
Pour the creamy cheese sauce evenly over the chicken and broccoli in the baking dish. Gently stir to ensure everything is well-coated.

Step 7: Add the Final Toppings
Sprinkle the remaining ½ cup of cheddar cheese and the 1 cup of mozzarella cheese over the top. For a crispy topping, mix the Panko breadcrumbs with the 2 tablespoons of melted butter and sprinkle it over the cheese.

Step 8: Bake to Bubbly Perfection
Bake in the preheated oven, uncovered, for 20-25 minutes, or until the casserole is bubbly around the edges and the topping is golden brown. If the top is browning too quickly, you can tent it loosely with foil.

Step 9: Rest and Serve
Remove the bake from the oven and let it rest for 5-10 minutes before serving. This allows the sauce to thicken slightly, making it easier to serve.

Tips for Success:

  • Don’t Overcook the Chicken: Searing it just until it’s no longer pink on the outside ensures it stays tender and juicy during baking.
  • Shred Your Own Cheese: Pre-shredded cheese contains anti-caking agents that can make your sauce grainy. Block cheese that you shred yourself will melt much more smoothly.
  • Room Temperature Milk: Using milk that isn’t ice-cold will help it incorporate into the roux more easily and prevent the sauce from being lumpy.
  • Blanch Your Broccoli (Optional): For bright green, perfectly crisp-tender broccoli, blanch the fresh florets in boiling water for 2 minutes, then plunge them into ice water before adding to the bake.
  • Let it Rest: Allowing the casserole to rest after baking is key for the perfect, non-soupy consistency.

Equipment Needed:

  • 9×13 inch Baking Dish
  • Large Skillet
  • Whisk
  • Measuring Cups and Spoons
  • Grater (for cheese)

Variations of Cheesy Chicken and Broccoli Bake:

  • “Rice-a-Roni” Style: Stir 1 cup of uncooked long-grain white rice into the sauce mixture before baking. You will need to add an extra 1 ½ cups of chicken broth and extend the baking time to 45-50 minutes, covered for the first 30 minutes.
  • Cauliflower Swap: Replace the broccoli with an equal amount of cauliflower florets.
  • Buffalo Chicken Version: Toss the cooked chicken in ½ cup of buffalo sauce before adding it to the dish. Use a Colby-Jack or Pepper Jack cheese blend.
  • Ham and Broccoli Bake: Substitute the chicken with 2 cups of diced cooked ham.
  • Gluten-Free: Use a 1:1 gluten-free flour blend for the roux and ensure all other ingredients are certified gluten-free.

Serving Suggestions for Cheesy Chicken and Broccoli Bake:

  • The Classic Combo: Serve a generous scoop over a bed of steamed white rice or egg noodles.
  • With a Fresh Contrast: Pair it with a simple side salad with a tangy vinaigrette to cut through the richness.
  • As a Standalone Feast: This casserole is so complete that it can easily be the star of the meal without any sides.
  • Potluck Perfection: It travels well and holds its heat, making it an ideal dish to share.

FAQs about Cheesy Chicken and Broccoli Bake:

Q: Can I make this ahead of time?
A: Absolutely. You can assemble the entire casserole (through Step 7), cover it tightly, and refrigerate it for up to 24 hours. When ready to bake, you may need to add 5-10 minutes to the baking time since it will be starting from cold.

Q: Can I use frozen broccoli without cooking it first?
A: Yes! This is a great time-saver. There is no need to thaw it. Just add the frozen florets directly to the baking dish with the chicken. The baking time and the hot sauce will cook it perfectly.

Q: How do I store and reheat leftovers?
A: Store in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave, or reheat the entire casserole, covered with foil, in a 350°F (175°C) oven for 15-20 minutes until hot.

Q: My sauce is too thin. How can I thicken it?
A: If the sauce seems thin after baking, let it rest for a full 10-15 minutes; it will thicken as it cools. You can also mix 1 tablespoon of cornstarch with 2 tablespoons of cold water and stir it into the casserole, then return it to the oven for 5-10 minutes.

Q: Can I freeze this casserole?
A: Yes, it freezes well. Assemble the casserole (without the Panko topping) and freeze before baking. Thaw in the refrigerator overnight, add the topping, and bake as directed. The texture of the broccoli may be slightly softer after freezing.
