Chicken Broccoli Potato Casserole this Recipe

Ingredients:

  • For the Chicken:
    • 2 lbs boneless, skinless chicken breasts, cut into 1-inch cubes
    • 1 tablespoon olive oil
    • 1 teaspoon garlic powder
    • 1 teaspoon onion powder
    • 1/2 teaspoon paprika
    • 1/4 teaspoon black pepper
    • 1/4 teaspoon salt, or to taste
  • For the Broccoli and Potatoes:
    • 1 large head of broccoli, cut into florets (about 4 cups)
    • 2 lbs Yukon Gold potatoes, peeled and cut into 1-inch cubes
    • 2 tablespoons olive oil
    • 1/2 teaspoon salt
    • 1/4 teaspoon black pepper
  • For the Cheese Sauce:
    • 1/2 cup (1 stick) unsalted butter
    • 1/2 cup all-purpose flour
    • 4 cups milk (whole or 2%)
    • 1 teaspoon salt
    • 1/2 teaspoon black pepper
    • 1/4 teaspoon nutmeg (optional, but adds a nice warmth)
    • 4 cups shredded cheddar cheese (about 16 oz)
    • 1 cup shredded Gruyere cheese (optional, but adds a great flavor depth)
  • For the Topping (Optional):
    • 1 cup panko breadcrumbs
    • 2 tablespoons melted butter
    • 1/4 cup grated Parmesan cheese

Preparing the Chicken

Okay, let’s start with the chicken. This is a super simple step, but it’s important to get it right because nobody wants bland chicken in their casserole!

  1. Prep the Chicken: Cut your chicken breasts into bite-sized cubes, about 1-inch in size. This ensures they cook evenly and are easy to eat in the casserole.
  2. Season the Chicken: In a large bowl, toss the chicken cubes with olive oil, garlic powder, onion powder, paprika, salt, and pepper. Make sure every piece is nicely coated with the spices. This is where the flavor party starts!
  3. Cook the Chicken: Heat a large skillet over medium-high heat. Add the seasoned chicken and cook until it’s cooked through and lightly browned. This usually takes about 5-7 minutes, depending on the size of your cubes. Make sure the internal temperature reaches 165°F (74°C). Set the cooked chicken aside.

Preparing the Broccoli and Potatoes

Next up, we’re tackling the broccoli and potatoes. Roasting them brings out their natural sweetness and gives them a lovely texture that complements the creamy sauce.

  1. Prep the Vegetables: Preheat your oven to 400°F (200°C). While the oven is heating, cut the broccoli into florets and peel and cube the potatoes into 1-inch pieces.
  2. Season the Vegetables: In a large bowl, toss the broccoli and potatoes with olive oil, salt, and pepper. Again, make sure everything is evenly coated.
  3. Roast the Vegetables: Spread the broccoli and potatoes in a single layer on a large baking sheet. Roast for 20-25 minutes, or until the potatoes are tender and the broccoli is slightly browned. You might want to flip them halfway through to ensure even cooking.

Making the Cheese Sauce

Now for the star of the show – the creamy, cheesy sauce! This is a classic béchamel sauce with a generous helping of cheese, and it’s what brings everything together.

  1. Melt the Butter: In a large saucepan over medium heat, melt the butter.
  2. Make the Roux: Whisk in the flour and cook for 1-2 minutes, stirring constantly. This creates a roux, which is the base of our sauce. It should be smooth and slightly golden.
  3. Add the Milk: Gradually whisk in the milk, a little at a time, making sure to incorporate it fully before adding more. This prevents lumps from forming. Keep whisking until the mixture is smooth.
  4. Simmer the Sauce: Bring the sauce to a simmer, stirring constantly. Reduce the heat to low and continue to simmer for 5-7 minutes, or until the sauce has thickened slightly. It should be thick enough to coat the back of a spoon.
  5. Season the Sauce: Stir in the salt, pepper, and nutmeg (if using). Taste and adjust the seasoning as needed.
  6. Add the Cheese: Remove the saucepan from the heat and stir in the cheddar cheese and Gruyere cheese (if using) until they are completely melted and the sauce is smooth and creamy.

Assembling the Casserole

We’re almost there! Now it’s time to put everything together and bake it to golden perfection.

  1. Combine Ingredients: In a large bowl, combine the cooked chicken, roasted broccoli and potatoes, and the cheese sauce. Gently stir everything together until it’s well combined.
  2. Transfer to Baking Dish: Pour the mixture into a greased 9×13 inch baking dish.
  3. Prepare the Topping (Optional): In a small bowl, combine the panko breadcrumbs, melted butter, and Parmesan cheese. Sprinkle the mixture evenly over the top of the casserole.
  4. Bake the Casserole: Bake in the preheated oven at 350°F (175°C) for 20-25 minutes, or until the casserole is bubbly and the topping is golden brown.
  5. Let it Rest: Let the casserole rest for 5-10 minutes before serving. This allows the sauce to thicken slightly and makes it easier to serve.

Tips and Variations:

  • Spice it up: Add a pinch of red pepper flakes to the cheese sauce for a little heat.
  • Add other vegetables: Feel free to add other vegetables like carrots, cauliflower, or peas to the casserole.
  • Use different cheese: Experiment with different types of cheese in the sauce, such as Monterey Jack, Colby Jack, or pepper jack.
  • Make it ahead: You can assemble the casserole ahead of time and store it in the refrigerator for up to 24 hours. Add a few extra minutes to the baking time if baking from cold.
  • Use rotisserie chicken: To save time, use shredded rotisserie chicken instead of cooking your own.
  • Add a crispy onion topping: Sprinkle some crispy fried onions on top of the casserole before baking for added flavor and texture.

Chicken Broccoli Potato Casserole

Conclusion:

This Chicken Broccoli Potato Casserole isn’t just another weeknight dinner; it’s a comforting, flavorful experience that the whole family will adore. From the creamy, cheesy sauce to the tender chicken, perfectly cooked broccoli, and satisfying potatoes, every bite is a symphony of textures and tastes.

If you’re looking for a lighter option, you can substitute the heavy cream with half-and-half or even Greek yogurt for a tangy twist. You could also add other vegetables like mushrooms, carrots, or bell peppers to boost the nutritional value and add even more flavor.

This casserole is fantastic on its own as a complete meal, but it also pairs beautifully with a simple side salad or some crusty bread for soaking up all that delicious sauce. For a more elegant presentation, you can bake it in individual ramekins.
