This recipe transforms a comfort food favorite into a keto-friendly masterpiece that your whole family will love. And the best part? It’s simple to prepare, so you can spend less time cooking and more time enjoying your meal.

Why This Recipe Stands Out

When I first discovered this recipe, I knew it was something special. It delivers all the rich, savory flavors of traditional Chicken Parmesan — crispy chicken, gooey cheese, and tangy tomato sauce — but without the breading and extra carbs.

What’s even better is that this casserole is versatile. You can make it with homemade tomato sauce or a store-bought no-sugar-added marinara, making it adaptable for busy schedules. This flexibility makes it an ideal recipe for anyone embracing a keto lifestyle.

A Bit About the Inspiration

This recipe was inspired by the love of comfort food with a keto twist. Just like in the cookbook Easy Keto Dinners by Carolyn Ketchum, it blends convenience with flavor. Carolyn is known for creating recipes that are approachable yet delicious, proving that keto doesn’t have to be complicated.

In fact, Easy Keto Dinners contains over 50 simple yet flavorful recipes, all made from everyday ingredients. That’s exactly the spirit behind this casserole — making a classic dish accessible while keeping it low-carb.

The Joy of Casseroles

There’s something undeniably satisfying about casseroles. They combine flavor, ease, and comfort into one dish. Especially on a busy night, tossing everything together and letting the oven do the work is a relief.

This keto casserole isn’t just about convenience — it delivers in taste. With rich Italian seasoning, savory chicken, and a creamy cheese topping, it’s a dish that feels indulgent without derailing your dietary goals.

A Quick Note on Tomato Sauce

One of the secrets to this recipe’s flavor is the tomato sauce. Carolyn includes a special Cheater’s Tomato Sauce recipe in her cookbook, which is perfect for keeping things low carb. But if you’re short on time, you can easily swap this out for a no-sugar-added marinara from your local store. Rao’s Homemade Marinara, for example, has just 3 net carbs per ½ cup and works wonderfully here.

This small adjustment allows you to whip up this keto casserole without skipping a beat, making it even more practical for weeknight dinners.

Keto-Friendly Macros That Impress
