Ingredients

  • 1.5 pounds (680g) chicken breast – boneless and skinless
  • 4 cups broccoli florets – fresh or frozen
  • 1 cup shredded cheddar cheese – divided
  • 1 cup shredded mozzarella cheese
  • 1/2 cup cream cheese – softened
  • 1/2 cup heavy cream
  • 1/2 cup sour cream
  • 1/4 cup grated Parmesan cheese
  • 1/4 cup unsalted butter
  • 1 medium onion – finely diced
  • 2 cloves garlic – minced
  • 1 tsp salt (to taste)
  • 1/2 tsp black pepper
  • 1/2 tsp smoked paprika
  • 1/4 tsp ground mustard (optional, for added flavor)
  • 1/4 tsp dried thyme
  • 1/4 tsp dried basil
  • Olive oil or non-stick spray for greasing

Instructions

Step 1: Preheat and Prepare the Baking Dish

  1. Preheat your oven to 375°F (190°C).
  2. Lightly grease a 9×13-inch baking dish with olive oil or non-stick spray to prevent sticking and to make cleaning up easier later on.

Step 2: Cook the Chicken

  1. Bring a pot of water to a boil, add a pinch of salt, and place the chicken breasts in the boiling water.
  2. Boil for about 10-12 minutes or until the chicken is fully cooked through (internal temperature should reach 165°F/74°C).
  3. Remove the chicken from the water and allow it to cool slightly. Once cooled, shred the chicken into bite-sized pieces using two forks or a knife.

Step 3: Prepare the Broccoli

  1. While the chicken is cooking, prepare the broccoli by blanching it in boiling water for 2-3 minutes if using fresh florets. This helps to soften the broccoli without making it mushy.
  2. If using frozen broccoli, simply thaw it according to package instructions.
  3. Drain the broccoli well and pat it dry to prevent extra water from diluting the casserole.

Step 4: Make the Creamy Cheese Sauce

  1. In a large skillet, melt the butter over medium heat. Add the diced onion and cook until softened, about 3-4 minutes.
  2. Add minced garlic and cook for another minute until fragrant, ensuring not to burn it.
  3. Reduce the heat to low, then add the cream cheese, heavy cream, and sour cream. Stir continuously until smooth and well combined.
  4. Add in the grated Parmesan, half of the shredded cheddar, and half of the shredded mozzarella. Stir until all the cheeses are melted and the sauce is creamy.
  5. Season the sauce with salt, black pepper, smoked paprika, ground mustard, thyme, and basil. Taste and adjust seasoning as desired.

Step 5: Combine the Ingredients

  1. In a large mixing bowl, combine the shredded chicken, blanched broccoli, and creamy cheese sauce.
  2. Gently fold the mixture until all ingredients are evenly coated with the sauce.
  3. Pour the mixture into the prepared baking dish and spread it out evenly.

Step 6: Add the Topping

  1. Sprinkle the remaining shredded cheddar and mozzarella over the top of the casserole.
  2. For a crispier top, you can also sprinkle an extra tablespoon or two of grated Parmesan.

Step 7: Bake

  1. Place the casserole in the preheated oven and bake for 25-30 minutes, or until the top is golden brown and bubbly.
  2. If you prefer an extra crispy top, broil for an additional 2-3 minutes, watching closely to avoid burning.

Step 8: Serve and Enjoy

  1. Remove the casserole from the oven and let it cool for a few minutes.
  2. Serve warm and enjoy this hearty, keto-friendly dish.
