Ingredients in Keto Chicken Parmesan Casserole

This dish brings bold flavors with keto-friendly ingredients you’ll feel good about. Let’s take a look:

Chicken

Cooked, shredded, or chopped—this is the protein-packed base of the casserole. Rotisserie chicken works great here for extra convenience.

Marinara Sauce

Rich, garlicky, and low in sugar. Look for a keto-approved version or make your own to keep it extra clean and flavorful.

Mozzarella Cheese

Melty, stretchy, and perfectly gooey when baked—this is the glue that holds the whole dish together.

Parmesan Cheese

Sharp, salty, and nutty—adds that classic Chicken Parm flavor and crisps up beautifully on top.

Almond Flour or Crushed Pork Rinds

This is your secret to a crunchy topping without the carbs. Gives that perfect golden-brown finish we all love.

Italian Seasoning

A savory blend of herbs like oregano, basil, and thyme that ties everything together with those cozy, familiar Italian notes.

Garlic

Freshly minced or powdered—it adds depth and punch to the dish. Don’t skip it!

Olive Oil or Butter

Just a bit to help toast the topping and carry the flavors.

Instructions

Let’s dive into the steps to create this flavorful masterpiece:

Preheat Your Equipment

Preheat your oven to 375°F. It’s always best to get your oven nice and ready so everything bakes up evenly.

Combine Ingredients

In a large mixing bowl, combine the shredded chicken with the marinara sauce, garlic, and a sprinkle of Italian seasoning. Stir until everything is well coated and flavorful.

Prepare Your Cooking Vessel

Grease a baking dish with olive oil or non-stick spray. This keeps everything from sticking and helps that bottom layer get a little toasty.

Assemble the Dish

Spoon the chicken mixture into the prepared dish and spread it out evenly. Layer on the shredded mozzarella and Parmesan next, then top with a mix of almond flour (or pork rinds), more Parmesan, and a drizzle of olive oil or melted butter.

Cook to Perfection

Bake for 20–25 minutes, or until the cheese is bubbly and the top is golden and crisp. If you want extra browning, pop it under the broiler for a minute or two—but watch it carefully!

Finishing Touches

Let the casserole rest for 5 minutes after baking. This helps it set and keeps those cheesy layers intact when you serve.

Serve and Enjoy

Scoop onto plates, garnish with fresh basil or parsley if you’re feeling fancy, and dig in while it’s warm and gooey!

How to Serve Keto Chicken Parmesan Casserole

This dish is rich and satisfying on its own, but here are a few keto-friendly ideas to complete the meal:

Zucchini Noodles: A light, fresh base that soaks up all that saucy, cheesy goodness.
Cauliflower Rice: Keeps it low-carb and adds a mild, fluffy contrast.
Roasted Veggies: Think asparagus, Brussels sprouts, or broccoli tossed in olive oil and garlic.
Simple Side Salad: A crisp romaine salad with a lemony vinaigrette is the perfect complement to the warm, cheesy casserole.
On Its Own: Honestly? You don’t need a side. Just grab a fork and enjoy the comfort!

Additional Tips

Here are some extra tips to help you get the most out of this recipe:

Make It Ahead: Assemble the casserole and store it in the fridge for up to 24 hours before baking.
Go Spicy: Add red pepper flakes or a touch of hot sauce if you like heat.
Dairy-Free Option: Use dairy-free cheese alternatives if needed—just make sure they melt well!
Low-Oxalate Tip: If you’re watching oxalate levels, opt for pork rinds over almond flour for the topping.
Leftover Magic: Leftovers are just as good the next day! Store in an airtight container and reheat gently.
