Ingredients Equipment Method Notes

Ingredients
  

  • 2 lbs boneless, skinless chicken breast cut into 1-inch cubes
  • 4 cups fresh broccoli florets
  • 4 tbsp unsalted butter
  • 3 cloves garlic minced
  • 1.5 cups heavy cream
  • 4 oz cream cheese softened and cubed
  • 1 cup grated Parmesan cheese freshly grated
  • 1 tsp Italian seasoning
  • 1 tsp salt or to taste
  • 0.5 tsp black pepper or to taste
  • 2 cups shredded mozzarella cheese

Equipment

  • 1 9x13 inch Baking Dish
  • 1 Large Skillet

Instructions
 

  1. Preheat your oven to 375°F (190°C). Prepare your chicken, broccoli, and garlic as directed.
  2. In a large skillet, melt 1 tablespoon of butter over medium-high heat. Add the chicken, season with salt and pepper, and cook until golden and cooked through (5-7 minutes). Remove chicken and set aside.
  3. In the same skillet, melt the remaining 3 tablespoons of butter over medium heat. Add garlic and cook for 30 seconds until fragrant. Reduce heat to low, then whisk in the heavy cream and cream cheese until smooth. Stir in the Parmesan cheese until melted. Season with Italian seasoning, salt, and pepper.
  4. Return the cooked chicken to the skillet. Add the broccoli florets and stir to coat everything evenly in the sauce.
  5. Transfer the mixture to a 9x13 inch baking dish. Top with the shredded mozzarella cheese. Bake for 20-25 minutes, until the sauce is bubbly and the cheese is golden brown.

Notes

For the best texture, use fresh broccoli instead of frozen.
Grating your own cheese from a block will result in a smoother, creamier sauce.
Let the casserole rest for 5 minutes before serving to allow the sauce to set.
