Keto Chicken Parmesan Casserole

Snow was falling outside my kitchen window last winter when I threw this together using a rotisserie chicken I'd picked up earlier that day. The house filled with that incredible garlic and melted cheese smell that makes everyone wander into the kitchen asking, "Is it ready yet?"

My sister who swore she'd never do keto asked for the recipe after taking one bite. She couldn't believe something so rich and satisfying fit into a low-carb lifestyle.

Ingredients

• 2 cups cooked chicken breast: Rotisserie chicken works perfectly here and saves so much time
• 1 ½ cups sugar-free marinara sauce: Read those labels carefully, many brands sneak in added sugar
• 1 cup shredded mozzarella cheese: Divide this in half, one portion goes inside the mixture
• ½ cup grated Parmesan cheese: Also split this, half gets mixed into the chicken
• 4 oz cream cheese, softened: Let this sit on the counter for 30 minutes first
• 1 teaspoon dried Italian herbs: The blend really matters more than measuring perfectly
• ½ teaspoon garlic powder: Fresh garlic burns too easily in casseroles
• ¼ teaspoon salt: The Parmesan adds saltiness so go easy here
• ¼ teaspoon black pepper: Freshly cracked makes a noticeable difference
• ¼ cup pork rinds, crushed: Optional but creates that authentic breadcrumb texture
• 1 tablespoon chopped fresh basil: Add this at the very end for a pop of green

Instructions

Preheat your oven:

Set it to 375°F and grab a medium casserole dish, giving it a quick coating of cooking spray or butter

Mix the filling:

In a large bowl, combine your chicken with the softened cream cheese, half the mozzarella, half the Parmesan, and all those seasonings

Spread it out:

Press the chicken mixture evenly into your prepared dish, creating a nice flat layer for the sauce

Add the marinara:

Pour the sugar-free sauce over the top, spreading it gently with the back of a spoon so you don't disturb the chicken layer underneath

Layer the cheese:

Sprinkle the remaining mozzarella and Parmesan across the entire surface

Add the crunch:

Scatter those crushed pork rinds over everything if you're using them for that extra crispy topping

Rest and garnish:

Give it five minutes to set, then scatter fresh basil on top before serving

Save

My husband actually asked if we could have this every Monday night now. That's saying something for someone who used to insist Italian food needed pasta on the plate.

Making It Your Own

Sometimes I sneak in sautéed spinach or chopped cooked bacon when I want to bulk it up. The variations are endless and still keep it keto-friendly.

Pairing Suggestions

A simple green salad with olive oil and vinegar is all you really need on the side. Roasted broccoli or cauliflower also works beautifully.

Meal Prep Magic

This casserole keeps in the refrigerator for up to five days and actually tastes better after the flavors have time to meld together.

• Portion it into individual containers for easy grab and go lunches
• Freeze portions for those nights when cooking feels impossible
• Reheat covered at 350°F until hot throughout

Save

There's something deeply satisfying about comfort food that doesn't leave you feeling heavy afterward. This keto chicken parmesan proves you don't have to sacrifice flavor for your health goals.

Your Recipe Questions Answered

→ 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 baking cold from the refrigerator.

→ What can I substitute for pork rinds?

Crushed almonds, almond flour, or additional Parmesan cheese work well as low-carb alternatives. You can also omit the crispy topping entirely.

→ Is this freezer-friendly?

Absolutely. Freeze before baking for up to 3 months. Thaw overnight in the refrigerator and bake as directed, adding extra time if needed.

→ Can I use raw chicken instead of cooked?

Cook the chicken first for best texture and food safety. Raw chicken releases too much liquid during baking and may result in a watery casserole.

→ How do I store leftovers?

Keep refrigerated in an airtight container for 3-4 days. Reheat in the oven at 350°F until hot and bubbly, or microwave individual portions.

→ Can I add vegetables to this casserole?

Sautéed spinach, mushrooms, or bell peppers mix beautifully into the chicken layer. Just cook them first to remove excess moisture before adding.
