Cooking Instructions

  1. Preheat the oven to 375°F (190°C). This temperature ensures that the casserole cooks evenly without drying out the chicken or vegetables.
  2. Season the chicken breasts generously with salt, freshly ground black pepper, and a sprinkle of Italian seasoning: don’t be shy with the seasoning! This step is very important to add flavor to the chicken, especially since we are using lean cuts for this keto recipe. For added depth of flavor, consider using a smoked paprika or poultry seasoning blend.
  3. Cook the chicken in a skillet over medium heat with a pat of butter or a drizzle of olive oil, until cooked through and no pink in the middle, about 7-8 minutes per side: here, the medium heat provides a nice sear evenly on the outside of the chicken. Allow time to cook. To ensure perfect doneness, use a meat thermometer and aim for an internal temperature of 165°F (74°C). If your chicken breasts are thick, thin them out a bit before cooking to cook them through.
  4. Once cooked, remove the chicken from the skillet and let it rest for a few minutes on a cutting board lined with foil before slicing it into bite-sized pieces: this resting step allows the chicken’s juices to redistribute, resulting in more tender and flavorful meat.
  5. Steam broccoli florets for 4 to 5 minutes, until tender-crisp: Steaming is a gentle cooking method that helps preserve broccoli’s vibrant green color and nutrients. Suppose you don’t have a steamer, blanch broccoli florets in boiling water for a similar effect.
  6. Pulse the cauliflower in a food processor fitted with the shredding blade until it is reduced to rice-sized pieces: this is a brilliant low-carb alternative to the traditional pasta in the casserole. If you don’t have a food processor, you can get a similar result by finely grating the cauliflower florets with a box grater.
  7. Using a spiralizer or vegetable julienne peeler, cut the zucchini into long, thin noodles similar to fettuccine: These zucchini noodles add a delightful textural element to the casserole and provide an extra serving of vegetables.
  8. In a saucepan over medium heat, melt the butter and fry the minced garlic for about 30 seconds, until fragrant: roasting the garlic releases its aromatic flavors which will infuse the whole Alfredo sauce. Be careful not to brown the garlic, as it can become bitter.
  9. Stir in the heavy cream and bring to a simmer, whisking occasionally: heating the cream thickens it slightly and helps it blend smoothly with the other ingredients in the sauce.
  10. Add the cubed cream cheese to the simmering cream mixture and stir constantly until melted and fully incorporated: Cream cheese adds richness and tang to Alfredo sauce. Using a whisk ensures that no lumps form.
  11. Next, stir in your favorite keto-friendly store-bought alfredo sauce or your own homemade version: this provides the base flavor for the sauce. For extra flavor, consider adding a splash of grated nutmeg or a pinch of white pepper.
  12. Grate fresh Parmesan cheese directly into the sauce and rub until melted and well combined: Parmesan cheese adds depth of saltiness and nutty flavor to the sauce.
  13. Season the alfredo sauce with salt, freshly ground black pepper, and a pinch of red pepper flakes (optional): Adjust the seasonings to your taste preference.
  14. In a large bowl, combine cooked and shredded chicken, steamed broccoli florets, fresh spinach, riced cauliflower, and zucchini noodles: this is where all the delicious ingredients of the casserole come together.
  15. Pour the creamy alfredo sauce over the mixture and toss gently with tongs or a large spoon to coat all the ingredients evenly: folding or tossing with gentle hands prevents the delicate zucchini noodles from breaking up.
  16. Transfer the mixture to a greased baking dish: this ensures easy removal of the casserole after baking.
  17. Generously top the casserole with shredded mozzarella cheese: Mozzarella cheese adds a nice gooey texture and a cheesy finish to the casserole.
  18. Bake the casserole in a preheated oven at 375°F (190°C) for 20-25 minutes, or until the cheese is melted and bubbly: the casserole is done when the cheese is golden brown and the filling is heated through.
  19. Let the casserole rest for 5-10 minutes before serving: this allows the cheese to set slightly and prevents mouth irritation.
  20. Serve hot and enjoy this delicious low-carb twist on a classic chicken alfredo dish!

Variation

  1. If you love vegan then substitute chicken with sautéed mushrooms, spinach, and bell peppers.
  1. Replace chicken with shrimp or scallops for a delightful seafood twist. The seafood twist is my personal favorite.
  1. Try adding cayenne pepper or red pepper flakes for a spicy kick to the keto chicken alfredo casserole with cream cheese.
  1. Try steamed broccoli florets for added texture and nutrition to the keto chicken alfredo casserole.
