Keto Chicken Parmesan Casserole

The kitchen smelled like an Italian trattorio the evening I first experimented with keto versions of my favorite comfort foods. My husband looked skeptical when I mentioned chicken parmesan without breading, but that first bubbling casserole won him over completely. Now it is the Wednesday dinner we actually look forward to after busy days.

Last month my sister-in-law stayed for dinner and went back for thirds before finally asking what made it so rich. I watched her face light up when I told her the entire thing was keto-friendly. She texted me the next morning saying her family had already requested it for their weekly meal rotation.

Ingredients

• 2 cups cooked chicken breast: Rotisserie chicken works beautifully here and saves so much time on busy weeknights
• 1 ½ cups sugar-free marinara sauce: Read labels carefully because many brands sneak in hidden sugars
• 1 cup shredded mozzarella cheese: This creates that irresistible cheese pull in every serving
• ½ cup grated Parmesan cheese: Adds that salty, nutty depth that makes Italian food taste authentic
• 4 oz cream cheese, softened: The secret ingredient that makes the chicken mixture luxuriously creamy without heavy cream
• 1 teaspoon dried Italian herbs: Dried oregano, basil, and thyme blend works perfectly here
• ½ teaspoon garlic powder: Fresh garlic can burn in the oven so powder gives consistent flavor throughout
• ¼ teaspoon salt: Adjust based on how salty your Parmesan and chicken already are
• ¼ teaspoon black pepper: Adds just enough bite to balance the rich cheeses
• ¼ cup pork rinds, crushed: Creates that crunch everyone misses on keto without the carbs
• 1 tablespoon chopped fresh basil: Adds a bright, fresh finish against all the rich, warm flavors

Instructions

Preheat and prepare your baking dish:

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

Mix the creamy chicken filling:

Combine the chicken, cream cheese, half the mozzarella, half the Parmesan, and all seasonings in a large bowl until everything is evenly distributed.

Spread and layer:

Press the chicken mixture into your prepared dish, then pour the marinara sauce over the top and spread it gently to cover.

Add the cheesy topping:

Sprinkle the remaining mozzarella and Parmesan across the entire surface, then scatter crushed pork rinds if you want extra crunch.

Bake until golden:

Slide the dish into the oven for 25 to 30 minutes until the sauce bubbles up around the edges and the cheese turns golden brown.

Rest and serve:

Let the casserole cool for about 5 minutes so the cheese sets slightly, then scatter fresh basil over the top and serve warm.

Save

My neighbor smelled this baking through our open kitchen window one Sunday and texted me immediately asking what I was making. She came over with a plate of zucchini noodles just to try a forkful, and left with the full recipe written on a napkin.

Making Ahead and Storage

I have learned through experimentation that this casserole actually tastes better the next day. The flavors meld together beautifully overnight in the refrigerator, making it perfect for meal prep Sundays.

Creative Variations

Adding a handful of sautéed spinach or chopped cooked bacon into the chicken mixture takes this from great to outstanding. The spinach wilts into the creamy filling while bacon adds a smoky depth that pairs perfectly with Italian herbs.

Serving Suggestions

A crisp green salad with a simple vinaigrette cuts through the richness beautifully. Roasted broccoli or cauliflower also makes an excellent low-carb side that soaks up any extra sauce.

• Keep the portion sizes in mind because this dish is very filling thanks to all that protein and fat
• The leftovers reheat perfectly in the microwave but the oven restores the crispy cheese texture best
• If freezing, wrap tightly and thaw overnight in the refrigerator before baking at 350°F until heated through

Save

There is something deeply satisfying about serving comfort food that fits your lifestyle without anyone feeling like they are missing out. Enjoy every creamy, crunchy bite.

Recipe FAQ

→ Can I make this ahead of time?

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

→ What can I use instead of pork rinds?

Crushed pork rinds provide a crispy breadcrumb-like texture. For substitutions, try almond flour mixed with Parmesan, crushed pork-free pork rind alternatives, or simply omit for a cheesier top.

→ Is this casserole freezer-friendly?

Absolutely. Freeze unbaked for up to 3 months or freeze leftovers in individual portions. Thaw overnight in the refrigerator before reheating at 350°F until heated through.

→ Can I use uncooked chicken?

For best results, use cooked chicken as the recipe states. If using raw, cube and brown it first in a skillet before mixing with the other ingredients to ensure proper cooking and texture.

→ How do I store leftovers?

Store in an airtight container in the refrigerator for up to 4 days. Reheat in the microwave or oven at 350°F until warmed through and cheese is melty again.
