Keto Chicken Parmesan Casserole

I stumbled onto this recipe during one of those desperate weeknights when I wanted chicken parmesan but absolutely refused to spend an hour breading and frying individual cutlets. My keto journey had left me craving comfort food, and the idea of throwing everything into one dish felt almost too good to be true. That first bubbling casserole came out of the oven smelling exactly like an Italian grandmother's kitchen, and I knew I'd never go back to the traditional version.

Last winter my brother came over skeptical about anything keto actually tasting good. He watched me dump shredded chicken and cream cheese into a bowl and literally asked if we were having diet food for dinner. One bite later and he asked me to pack him a container for lunch the next day. Now he requests this casserole whenever he visits, which is basically the highest compliment I can imagine receiving.

Ingredients

• 2 cups cooked chicken breast: Rotisserie chicken works perfectly here and saves so much time, or bake some breasts ahead of time
• 1 ½ cups sugar-free marinara sauce: Read those labels carefully because hidden sugar lurks in so many marinara brands
• 1 cup shredded mozzarella cheese: Part of it gets mixed into the chicken for extra creaminess
• ½ cup grated Parmesan cheese: The real stuff makes a huge difference in flavor depth
• 4 oz cream cheese, softened: This is the secret ingredient that makes the filling incredibly rich and binds everything together
• 1 teaspoon dried Italian herbs: Fresh herbs are great but dried ones work beautifully in a baked dish
• ½ teaspoon garlic powder: Add more if you really love garlic like my family does
• ¼ teaspoon salt and pepper: Adjust based on how seasoned your cooked chicken already is
• ¼ cup crushed pork rinds: Totally optional but they give you that satisfying breadcrumb crunch
• 1 tablespoon fresh basil: The bright green color and fresh flavor on top makes the whole dish look and taste special

Instructions

Preheat and prep:

Get your oven to 375°F and grease a casserole dish with butter or olive oil

Mix the filling:

Combine the chicken, cream cheese, half of both cheeses, and all seasonings in a large bowl until everything is evenly distributed

Spread it out:

Press the chicken mixture into your prepared dish so it creates an even layer

Add the sauce:

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

Cheese it up:

Sprinkle the remaining mozzarella and Parmesan all over the sauce, then add crushed pork rinds if you are using them

Bake until bubbly:

Let it cook for 25 to 30 minutes until you see those gorgeous golden brown spots on top and the sauce is bubbling around the edges

The hardest part:

Let it rest for 5 minutes before serving because the filling holds heat like crazy, then garnish with fresh basil

This recipe has become my go-to for meal prep Sundays because it actually tastes better the next day when all those flavors have had time to hang out together. I love pulling a container out of the fridge for lunch and feeling like I am having something indulgent instead of another boring salad. There is something so satisfying about eating comfort food that also happens to fit perfectly into my lifestyle.

Make It Your Own

Sometimes I throw in a handful of sautéed spinach or chopped cooked bacon when I am mixing the chicken filling. The variations are endless and I have found that almost any keto-friendly addition works beautifully. My friend adds chopped sun-dried tomatoes and swears it takes the whole dish to another level.

Perfect Pairings

A simple green salad with an olive oil dressing cuts through the richness beautifully. I have also served this alongside roasted broccoli or cauliflower when I want something warm on the plate. The key is keeping sides light since the casserole itself is so satisfying and filling.

Storage and Reheating

This casserole keeps perfectly in the refrigerator for up to five days and actually freezes beautifully if you want to make a double batch. I reheat individual portions in the microwave for about two minutes, but the oven gives you that freshly baked texture again. Cover with foil if reheating in the oven so the cheese does not burn.

• Let the casserole cool completely before covering and storing to prevent condensation
• Frozen portions should be thawed overnight in the fridge before reheating
• Add a fresh sprinkle of Parmesan after reheating to revive that crispy top layer

There is nothing quite like pulling this bubbling, golden casserole out of the oven and watching everyone's faces light up. It is the kind of comfort food that happens to be good for you, and honestly, that is the best kind of recipe there is.

Recipe FAQs

→ Can I use raw chicken instead of cooked?

→ What can I substitute for pork rinds?

Crushed pork rinds add crunch, but you can omit them entirely or replace with almond flour mixed with Parmesan, crushed pork-free chips, or simply extra shredded cheese for that golden crispy top.

→ How do I store leftovers?

Store cooled portions 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 bubbly.

→ Can I freeze this casserole?

Yes! Assemble the entire casserole, wrap tightly with plastic and foil, and freeze for up to 3 months. Thaw overnight in the refrigerator before baking as directed.
