Ingredients You’ll Need

This recipe uses a handful of straightforward, wholesome ingredients that come together beautifully. Each one plays a key role in building those rich textures and layering those bold flavors that define the perfect Keto Chicken Parmesan Casserole.

• 4 cups cubed rotisserie chicken: Convenience meets flavor here—using pre-cooked chicken saves time and adds tenderness.
• 3/4 cup no added sugar marinara sauce: Keeps the dish low-carb while delivering that classic tomato tang.
• 1 tbsp Italian seasoning: This blend adds aromatic herbs that bring the whole dish to life.
• 2 garlic cloves, minced: Garlic infuses the casserole with a mouthwatering, savory depth.
• 1 tbsp olive oil: For sautéing garlic and creating a rich base of flavor.
• 2 tbsp almond flour: Helps to thicken the sauce naturally without extra carbs.
• 3/4 cup parmesan cheese, grated: Adds a nutty, salty bite essential for Parmesan perfection.
• 1 1/2 cups shredded mozzarella cheese: Brings melty, gooey texture you’ll want to dive into.
• 3/4 cup finely crushed parmesan crisps (or pork rinds): Creates a crispy, golden topping that’s pure indulgence.
• Non-stick cooking spray: Prevents sticking and keeps clean-up easy.

How to Make Keto Chicken Parmesan Casserole

Step 1: Prepare Your Oven and Garlic

Start by preheating your oven to 350 degrees Fahrenheit. While it warms up, heat the olive oil in a large skillet over medium heat. Toss in the minced garlic and sauté for about a minute, just until fragrant and golden. This step builds the flavorful foundation for your casserole and fills the kitchen with an irresistible aroma.

Step 2: Combine Chicken, Sauce, and Seasonings

Stir the Italian seasoning into the skillet, then pour in the marinara sauce along with the almond flour. The almond flour will gently thicken the sauce as it cooks. Now add the cubed chicken and mix everything until it’s well combined. Let the mixture simmer for about 5 minutes so those flavors blend perfectly and the chicken gets coated in the sauce.

Step 3: Assemble the Casserole

Coat a 9-by-13-inch casserole dish with non-stick cooking spray to ensure easy serving later. Pour the warm chicken and marinara mixture evenly into the dish. Then, layer on the parmesan cheese and mozzarella cheese, spreading them evenly. Finally, sprinkle the finely crushed parmesan crisps or pork rinds on top to create that signature crisp topping every bite needs.

Step 4: Bake to Melty, Golden Perfection

Place your assembled casserole in the oven and bake it for 25 to 30 minutes, or until the cheese is melted completely and the casserole is heated through. You’ll notice the top turning a beautiful golden brown with irresistible crispy edges. Once done, let it cool for a few minutes before serving—this helps the casserole set just right.

How to Serve Keto Chicken Parmesan Casserole

Garnishes

Fresh garnishes can really brighten up the dish, so consider sprinkling chopped fresh basil, parsley, or even a little red pepper flakes for a subtle kick. A drizzle of extra virgin olive oil right before serving can add a luscious finish as well.

Side Dishes

This casserole is wonderfully filling on its own, but pairing it with a crisp side salad or some roasted low-carb vegetables like asparagus or zucchini noodles makes the meal even more balanced and delightful. Garlic butter green beans also make a fantastic accompaniment.

Creative Ways to Present

For a fun twist, serve individual portions in small ramekins topped with extra parmesan crisps and a sprig of fresh herbs. You can also layer it over cauliflower rice for an especially hearty, keto-friendly presentation that guests will love.

Make Ahead and Storage

Storing Leftovers

Once cooled completely, store any leftovers in an airtight container in the refrigerator. This casserole keeps well for up to 3 days and remains just as flavorful and satisfying when reheated.

Freezing

You can absolutely freeze the Keto Chicken Parmesan Casserole for longer storage. Portion it into freezer-safe containers or wrap the whole casserole dish tightly with foil and plastic wrap. Freeze for up to 2 months. Thaw in the refrigerator overnight before reheating.

Reheating

Reheat leftovers in the oven at 350 degrees Fahrenheit for about 15-20 minutes or until warmed through and the cheese starts bubbling again. Alternatively, microwave individual portions on medium power in short bursts to avoid drying out the chicken.

FAQs

Can I use fresh chicken instead of rotisserie?

Absolutely! You can cook and cube chicken breasts or thighs yourself; just make sure they are fully cooked before combining with the other ingredients to ensure great texture and flavor.

What makes this casserole keto-friendly?

Yes! It freezes really well and makes for an excellent meal prep option. Just be sure to thaw it fully in the fridge before reheating to maintain the texture and flavor.
