Keto Chicken Parmesan Casserole

The smell of bubbling marinara and melting mozzarella always transports me back to my grandmother's tiny kitchen, where she'd somehow turn leftovers into something magical. One rainy Tuesday, I found myself staring at leftover rotisserie chicken and a jar of sugar-free marinara, wondering if I could recreate that cozy comfort without the carbs. My husband was skeptical when I mentioned the pork rind topping, but one bite converted him completely.

I first made this for a keto-conscious friend who was mourning the loss of her favorite Italian dishes. Watching her face light up when she took that first bubbling, golden bite reminded me why food is about so much more than nutrition—it's about feeling cared for and satisfied. Now she requests it every time she visits, and honestly, I never say no.

Ingredients

• 2 cups cooked chicken breast: Rotisserie chicken works beautifully here, saving you precious time while infusing the dish with extra flavor
• 1 ½ cups sugar-free marinara sauce: Look for brands with no added sugar or make your own—this simple choice keeps you firmly in ketosis
• 1 cup shredded mozzarella cheese: Part gets mixed in for creaminess and part creates that irresistible golden blanket on top
• ½ cup grated Parmesan cheese: The salty, nutty depth it adds transforms the entire casserole from good to absolutely exceptional
• 4 oz cream cheese, softened: This is the secret weapon that makes the chicken mixture incredibly creamy without any heavy cream or flour
• 1 teaspoon dried Italian herbs: I keep a small bowl of this homemade blend on my counter for whenever inspiration strikes
• ½ teaspoon garlic powder: Fresh garlic can burn in the oven, but powder distributes that savory flavor perfectly throughout
• ¼ teaspoon each salt and pepper: The cheese is already salty, so season carefully—taste as you go and adjust accordingly
• ¼ cup crushed pork rinds: My husband was horrified until he tried it—now he insists on extra for the crunch factor
• 1 tablespoon fresh basil: The pop of bright green and fresh flavor makes the finished dish look and taste restaurant worthy

Instructions

Prep your oven and dish:

Set your oven to 375°F and give a medium casserole dish a quick coating of oil or cooking spray while the oven heats up

Mix the creamy base:

In a large bowl, combine the chicken with softened cream cheese, half the mozzarella, half the Parmesan, and all those wonderful seasonings until everything is evenly distributed

Build your layers:

Press the chicken mixture into your prepared dish, then pour the marinara sauce over the top like a cozy blanket

Add the golden crown:

Sprinkle the remaining mozzarella and Parmesan across the sauce, then scatter those crushed pork rinds if you are brave enough to try them

Bake until bubbly:

Let it cook for 25 to 30 minutes until the edges are bubbling enthusiastically and that cheese has turned perfectly golden brown

The patience moment:

Give the casserole five minutes to rest so the flavors settle and the sauce thickens slightly, then scatter fresh basil over the top before serving

Pin it

This casserole became our go-to Sunday dinner after my sister started keto and complained about missing all her favorite comfort foods. There is something profoundly satisfying about watching someone take that first skeptical bite and then immediately reach for seconds.

Making It Ahead

I have assembled this the night before and baked it straight from the refrigerator with perfect results. Just add about five extra minutes to the baking time and you will have a hot, bubbling dinner waiting for you on busy weeknights.

Customizing Your Casserole

The beauty of this recipe lies in how easily it adapts to whatever vegetables or proteins you have on hand. I have added sautéed spinach, chopped cooked bacon, and even diced bell peppers when the garden was overflowing.

Serving Suggestions

A simple green salad with an olive oil dressing cuts through the richness beautifully. I also love serving this alongside roasted broccoli or cauliflower rice when I want a complete meal that feels substantial.

• Let the casserole rest before serving
• Grate your own Parmesan for the best flavor
• The pork rind topping is truly worth trying

This casserole proves that eating keto does not mean sacrificing comfort or flavor—sometimes the most satisfying meals are the ones that remind us of home, whatever that looks like for you.

Recipe FAQ

→ Can I make this ahead of time?

Yes, assemble the casserole up to 24 hours in advance and store covered in the refrigerator. Add 5-10 minutes to the baking time if cooking from cold.

→ What can I substitute for pork rinds?

Crushed pork rinds provide crunch but can be replaced with almond flour, crushed pork-free panko, or simply omitted for a still-delicious cheesy top layer.

→ Is this casserole freezer-friendly?

Absolutely. Wrap the cooled, baked casserole tightly and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating at 350°F until warmed through.

→ Can I use different cheeses?

While mozzarella and Parmesan create the classic flavor, you can substitute provolone, fontina, or Italian cheese blends. Avoid very soft cheeses as they may affect the texture.

→ How do I know when it's done?

The casserole is ready when the cheese is melted and golden brown, the sauce is bubbling around the edges, and the internal temperature reaches 165°F.
