This hearty keto chicken parmesan casserole transforms a traditionally carb-heavy Italian favorite into a delicious low-carb dream. The dish delivers all the comforting flavors and textures you crave without the guilt or afternoon energy crash. Perfect for busy weeknights when you want something satisfying but need to keep your carb count in check.
I first created this recipe during my early days of keto eating when I desperately missed Italian comfort food. What started as an experiment has become our family's most requested dinner even among the non-keto eaters at our table.
Ingredients
- Rotisserie chicken: Saves tremendous time and adds moisture and flavor
- Low sugar marinara sauce: Keeps carbs in check while delivering rich tomato flavor
- Cream cheese: Creates a luscious base that mimics the comfort of pasta
- Heavy cream: Adds richness and helps create the perfect sauce consistency
- Mozzarella cheese: Provides that classic stretchy cheese pull we all love
- Parmesan cheese: Creates the perfect crispy golden top
- Italian herbs: Infuse the dish with authentic flavor without adding carbs
- Garlic powder: Provides depth without the work of fresh garlic
Step-by-Step Instructions
- Prep Your Dish:
- Preheat your oven to 375°F and lightly grease a 9×9 baking dish. This temperature achieves the perfect balance of melting the cheese while creating those desirable crispy edges. Use a dish with some depth to allow proper layering of all components.
- Make the Creamy Base:
- Combine softened cream cheese heavy cream and seasonings until completely smooth. Take your time here as any lumps now will remain in the final dish. Fold in your shredded chicken ensuring every piece gets coated in the creamy mixture. This base is what makes the casserole satisfying without pasta.
- Layer It Up:
- Transfer the chicken mixture to your baking dish creating an even layer. Pour marinara sauce over the top without mixing it in. This creates distinct layers similar to traditional lasagna. Top with mozzarella first then Parmesan to create the ideal melt and browning effect.
- Bake Until Golden:
- Bake uncovered for 20–25 minutes watching for bubbling edges and a golden surface. The uncovered baking is crucial for developing flavor through caramelization rather than steaming. For an extra crispy top similar to traditional chicken parmesan broil for the final 2–3 minutes.
- Cool and Serve:
- Allow the casserole to rest for 5 minutes before serving. This resting period helps the layers set so you get clean portions rather than a sloppy mess. The flavors also intensify during this brief rest making for a more delicious final dish.

The combination of three different cheeses is what makes this casserole special. I discovered through multiple tests that using only mozzarella made the dish one-dimensional while the blend of cream cheese Parmesan and mozzarella creates layers of flavor and texture that make you forget you are eating a low-carb meal.
Make It Ahead
This casserole is perfect for meal prep. You can assemble everything up to the baking step cover tightly and refrigerate for up to 3 days. When ready to eat simply add an extra 10 minutes to the baking time if cooking directly from the refrigerator. The flavors actually develop nicely during this rest time making it even more delicious when you finally bake it.
Perfect Pairings
While completely satisfying on its own this casserole reaches new heights when paired strategically. Serve alongside roasted broccoli or asparagus drizzled with olive oil and lemon for a complete meal. For those not strictly counting carbs a small side of roasted cherry tomatoes provides a beautiful acid contrast to the rich casserole. For family members not following keto a side of garlic bread allows them to enjoy the same meal with some extra carbs.
Customization Options
This recipe welcomes personalization based on your preferences. Add spinach to the chicken mixture for extra nutrients or mix in diced pepperoni for an extra flavor punch. Swap the chicken for ground beef or turkey for a different protein profile. Try different cheese combinations like adding some fontina or provolone to the mix. For heat lovers increase the red pepper flakes or add some chopped jalapeños to the chicken mixture.

Frequently Asked Questions About the Recipe
- → Can I use chicken breasts instead of shredded rotisserie chicken?
Absolutely! You can cook and shred your own chicken breasts or thighs. Simply season with salt and pepper, bake or poach until cooked through (about 25 minutes at 375°F), then shred with two forks. This adds about 30 minutes to your prep time but works perfectly in the recipe.
- → What should I look for in a keto-friendly marinara sauce?
When choosing a marinara sauce, look for options with 5g of carbs or less per serving. Check the ingredient list for added sugars, as many commercial sauces contain sugar. Brands like Rao's, Primal Kitchen, and Yo Mama's are excellent keto-friendly options, or you can make your own using fresh tomatoes, olive oil, garlic, and herbs.
- → How can I store and reheat leftovers?
Store leftovers in an airtight container in the refrigerator for up to 3-4 days. For best results when reheating, use the oven at 350°F for about 15 minutes to maintain the crispy cheese top. Microwave reheating works too (1-2 minutes), though the texture won't be as perfect. The casserole also freezes well for up to 3 months—just thaw overnight before reheating.
- → Can I make this dairy-free while keeping it keto?
Yes, you can substitute the dairy components with alternatives. Use dairy-free cream cheese (like Kite Hill), coconut cream instead of heavy cream, and dairy-free cheese alternatives like Violife or Daiya. Note that this will alter the flavor profile somewhat, but will still produce a delicious casserole while maintaining the low-carb benefits.
- → What are the best low-carb sides to serve with this casserole?
Great low-carb side options include roasted broccoli, cauliflower rice, sautéed green beans with almonds, a simple arugula salad with olive oil and lemon, or roasted Brussels sprouts. For something more substantial, try keto garlic bread made with almond flour, or zucchini noodles tossed with olive oil and herbs.
- → How can I add more vegetables to this dish?
You can easily incorporate vegetables by adding a layer of spinach between the chicken and marinara, mixing in sautéed mushrooms or bell peppers with the chicken mixture, or adding chopped broccoli. Just make sure any vegetables you add are pre-cooked to remove excess moisture that could make the casserole watery.
