Ingredients
  

For the Casserole
  • 2 lbs boneless, skinless chicken breasts cut into 1-inch pieces
  • 1 lb broccoli florets about 5 cups
  • 1 tbsp olive oil
  • 1 tsp garlic powder
  • 1 tsp salt or to taste
  • 1/2 tsp black pepper or to taste
  • 1.5 cups shredded mozzarella cheese for topping
For the Keto Alfredo Sauce
  • 4 tbsp unsalted butter
  • 3 cloves garlic minced
  • 1.5 cups heavy cream
  • 4 oz cream cheese softened
  • 1 cup grated Parmesan cheese freshly grated

Equipment

  • 1 9x13 inch Baking Dish
  • 1 Large Skillet

Method
 

  1. Preheat your oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish.
  2. Season chicken pieces with garlic powder, salt, and pepper. Heat olive oil in a large skillet over medium-high heat. Cook the chicken until golden and cooked through. Transfer to the baking dish.
  3. Steam or blanch the broccoli florets for 2-3 minutes until tender-crisp. Drain well and add to the baking dish with the chicken.
  4. In the same skillet, melt the butter over medium heat. Add minced garlic and cook until fragrant (about 30 seconds).
  5. Reduce heat to low and whisk in the heavy cream and softened cream cheese until the mixture is completely smooth.
  6. Gradually stir in the grated Parmesan cheese until the sauce is smooth and has thickened. Season with additional salt and pepper if needed.
  7. Pour the Alfredo sauce over the chicken and broccoli. Stir gently to coat everything evenly. Sprinkle the shredded mozzarella cheese over the top.
  8. Bake for 15-20 minutes, or until the sauce is bubbling and the cheese is melted and golden brown. Let it rest for 5 minutes before serving.

Notes

For best results, use freshly grated Parmesan cheese as it melts much smoother than pre-shredded varieties.
Ensure your cream cheese is well-softened to prevent lumps in your sauce.
Don't overcook the broccoli before baking to avoid it becoming mushy.
