A creamy, cheesy low carb chicken alfredo bake packed with 40g of protein per serving. Easy to make and perfect for weekly meal prep or a satisfying weeknight dinner.
Preheat oven to 375 degrees F (190 degrees C) and grease a 9×13 inch baking dish.
Heat olive oil in a large skillet over medium-high heat. Add chicken pieces in a single layer and cook for 5 to 7 minutes until golden brown and cooked through with no pink inside. Add minced garlic and cook one more minute until fragrant.
In a mixing bowl, combine heavy cream, freshly grated Parmesan, softened cream cheese, Italian seasoning, salt, and pepper. Stir until completely smooth with no lumps.
Pour the cream mixture over the chicken in the skillet. Add chicken broth and stir well to combine. Add broccoli florets if using and stir them in.
Transfer the mixture to the prepared baking dish and spread into an even layer.
Sprinkle shredded mozzarella cheese evenly over the entire surface.
Bake for 20 to 25 minutes until cheese is bubbly and lightly golden. For a crispier top, broil for the final 2 to 3 minutes, watching closely.
Remove from oven and rest for 3 to 5 minutes before serving to allow the sauce to thicken slightly.
Notes
For extra protein, stir one scoop of unflavored protein powder into the sauce before baking. It blends in completely and does not affect flavor.
If the sauce is too thick before baking, add a splash more chicken broth. It will firm up as it rests after baking.
Freshly grated Parmesan melts more smoothly than pre-packaged shredded varieties and produces a creamier sauce.
