Keto Chicken Parmesan Casserole

My friend Sarah swore she'd never give up pasta until I served this at our weekly dinner get-together. She took three bites, fork froze mid-air, and asked what kind of magic low-carb noodle I'd discovered. The pure joy on her face when I told her it was all chicken and cheese still makes me laugh every time I make it.

Last winter my husband came down with a terrible flu and couldn't keep much food down except warm comfort meals. I made a triple batch of this casserole and that simple dish somehow became the highlight of his sick week. Now he requests it whenever he's feeling under the weather, which I find absolutely charming.

Ingredients

• 2 cups cooked chicken breast, shredded or diced: Rotisserie chicken works perfectly here and saves about twenty minutes of prep time
• 1 ½ cups sugar-free marinara sauce: Read those labels carefully because sugar hides in unexpected places
• 1 cup shredded mozzarella cheese: Divide this in half before you start cooking so you dont forget
• ½ cup grated Parmesan cheese: The real stuff from the cheese counter melts better than the green shaker can
• 4 oz (115 g) cream cheese, softened: Leave it on the counter for thirty minutes before you begin
• 1 teaspoon dried Italian herbs: Homemade herb blends work great if you have them
• ½ teaspoon garlic powder: Fresh garlic burns in the oven so powder is actually better here
• ¼ teaspoon salt: Adjust up or down depending on how salty your marinara and cheeses are
• ¼ teaspoon black pepper: Freshly ground makes a noticeable difference
• ¼ cup pork rinds, crushed (for crunch, optional): These create the most incredible crispy topping
• 1 tablespoon chopped fresh basil (for garnish): Dont skip this because the bright flavor cuts through all that rich cheese

Instructions

Preheat and prep your baking dish:

Set your oven to 375°F (190°C) and give a medium casserole dish a quick coating of oil or butter.

Make the creamy chicken base:

Mix the cooked chicken, softened cream cheese, half the mozzarella, half the Parmesan, Italian herbs, garlic powder, salt, and pepper in a large bowl until everything is well combined.

Spread the mixture:

Press the chicken mixture evenly into your prepared baking dish using the back of a spoon.

Add the saucy layer:

Pour the marinara sauce over the chicken and spread it gently so you dont disturb the layer underneath.

Create the cheesy crust:

Sprinkle the remaining mozzarella and Parmesan over the top, then add crushed pork rinds if you're using them.

Bake until golden:

Slide the dish into the oven for 25 to 30 minutes until you see bubbling sauce and beautifully browned cheese.

Rest and garnish:

Let the casserole sit for five minutes so it sets up, then scatter fresh basil over the top before serving.

This recipe became my go-to contribution for family potlucks after my uncle who claims to hate all diet food went back for seconds. His wife pulled me aside later to get the recipe because he kept talking about it the whole way home.

Making It Your Own

I've discovered that adding sautéed spinach or chopped cooked bacon to the chicken mixture takes this from great to absolutely incredible. The bacon adds smoky depth while spinach brings a fresh element that balances the richness.

The Perfect Side Dish

A crisp green salad with an olive oil vinaigrette or some roasted broccoli and cauliflower completes the meal perfectly. Something fresh and bright on the plate keeps every bite interesting.

Meal Prep Magic

This casserole meal preps like a dream and actually tastes better on day two when all the flavors have had time to become friends. Cut it into individual portions before storing so you can grab exactly what you need throughout the week.

• Store in airtight containers for up to five days in the refrigerator
• Freeze individual portions for those busy weeknights when cooking feels impossible
• Reheat at 350°F until heated through, about 15 to 20 minutes

There's something deeply satisfying about serving comfort food that fits your lifestyle without feeling like a compromise at all. Enjoy every bite.

Recipes Q&A

→ Can I make this ahead of time?

Assemble the entire casserole up to 24 hours in advance, refrigerate covered, then bake when ready. You may need an additional 5–10 minutes of cooking time if baking from cold.

→ What other proteins work well?

Ground turkey or leftover roasted pork make excellent substitutes. For a vegetarian version, use a mixture of ricotta and chopped spinach instead of chicken.

→ Can I freeze leftovers?

Yes, portion cooled leftovers into airtight containers and freeze for up to 3 months. Thaw overnight in the refrigerator and reheat at 350°F until warmed through.

→ How do I get the crispiest cheese topping?

Broil for 2–3 minutes at the end of cooking, watching closely to prevent burning. The pork rind layer also creates an exceptional crunchy texture while adding virtually no carbs.

→ What vegetables pair nicely?

Serve alongside roasted broccoli, cauliflower, zucchini noodles, or a crisp green salad with olive oil and vinegar dressing for a complete low-carb meal.
