Ingredient Lowdown
- Cooked chicken (2 cups): Shredded or diced, it provides hearty protein and a tender base.
- Sugar-free marinara sauce (2 cups): Choose a low-carb, no-sugar-added version to keep it keto-friendly and flavorful.
- Mozzarella cheese (1 cup, shredded): Melts beautifully for a gooey, toasty topping.
- Grated Parmesan cheese (½ cup): Adds a sharp, nutty kick that complements the marinara.
- Italian seasoning (1 tsp): A fragrant blend to deepen savory notes without fuss.

Set Up for Success
Before diving in, make sure your oven is preheated to 375°F (190°C). This steady, moderate heat encourages that perfect cheese melt and golden top without drying out the chicken. I always like to give my 9×13-inch baking dish a light coating of olive oil — it keeps every bite coming out clean and adds a subtle toasty undertone on the edges.

Step-by-Step: Keto Chicken Parmesan Casserole Recipe
- Preheat oven: Set to 375°F (190°C) so it’s ready when your casserole is assembled.
- Mix the base: In a large bowl, combine the cooked chicken, marinara sauce, minced garlic, Italian seasoning, salt, and pepper. Take a moment to smell the fragrant garlic and herbs—the aroma sets the tone for the whole dish.
- Prepare the baking dish: Lightly grease with olive oil, especially the edges, to avoid sticking and create a lovely crisp crust.
- Transfer mixture: Pour your flavorful chicken and sauce blend into the baking dish, spreading it evenly.
- Top with cheese: Generously sprinkle shredded mozzarella and grated Parmesan over the surface, covering every corner for that rich, bubbly finish.
- Bake to golden perfection: Place in the oven and bake for 25–30 minutes. You’ll know it’s ready when the cheese is melted, bubbly, and gloriously golden with some toasted edges that add texture.
Chef’s Notes & Success Tips
Using shredded chicken rather than large chunks helps the sauce cling better, giving you evenly flavored bites. When spreading the cheese, don’t skimp—it’s the key to that signature golden bubbly crust. If your marinara is very watery, consider simmering it down a bit first to avoid soggy edges. Let the casserole rest for 5-10 minutes after baking; this settles the layers and improves slicing.
Flavor Twists for Keto Chicken Parmesan Casserole Recipe
- Add fresh basil or oregano for a vibrant herbal lift right before serving.
- Stir in sautéed mushrooms or spinach into the chicken mixture for extra veggies and earthiness.
- Swap mozzarella for provolone or fontina for a gooier, more buttery melt.
- For a spicy kick, mix in red pepper flakes or a dash of smoked paprika.
- Try topping with a sprinkle of crushed pork rinds for a crispy, keto-friendly crust upgrade.
Storage & Make-Ahead Tips
- Refrigerate: Store leftovers covered in the fridge for up to 3 days—reheat gently to preserve moisture.
- Freeze: Assemble but don’t bake, cover tightly, and freeze up to 2 months. Thaw overnight before baking.
- Reheat: Warm in a 350°F oven for 15–20 minutes for best texture; microwave reheats quickly but can make cheese rubbery.
- Make ahead: Cook the chicken and prep the sauce a day ahead to speed up assembly on a busy evening.
