Chicken Parmesan is one of those classic comfort dishes that always hits the spot — and it happens to be one of my family’s favorites. But I wanted to create a version that’s healthier, keto-friendly, and gluten free without losing any of the flavors that make it so irresistible. That’s how this Low Carb Chicken Parmesan Casserole was born.
This recipe transforms the traditional Italian favorite into a wholesome, low carb dish without compromising taste or texture. It’s perfect for busy weeknights, family dinners, or even meal prepping for the week. Plus, it’s a guaranteed crowd-pleaser whether your guests follow keto, gluten free, or simply crave a hearty comfort meal.
Why This Low Carb Chicken Parmesan Works So Well
Instead of the usual bread crumbs, I use a flavorful coating of almond flour mixed with Parmesan cheese and Italian herbs. This not only keeps the dish low carb but also adds a nutty, cheesy crunch that rivals traditional breading. The result? Crispy chicken bites smothered in a rich tomato sauce and gooey melted mozzarella cheese — comfort food at its finest.
Over time, this coating has become my go-to for chicken, pork chops, and even low carb fried eggplant. It’s easy to prepare and adds a flavor boost without the extra carbs.
Why I Chose the Casserole Style
While I sometimes serve chicken parmesan alongside pasta for my family, I wanted to make a dish that’s easy to serve and perfect for leftovers. Turning it into a casserole solved both problems.
For this recipe, I cut the chicken into smaller chunks before breading and frying them. This simple step means you get more crispy coating in every bite — something I believe is essential for chicken parmesan lovers. It also makes portioning quick and convenient, especially if you’re serving a crowd.
Comfort in Every Bite
Imagine this: tender chicken bites with a crispy coating, bright and tangy tomato sauce, and layers of stretchy mozzarella cheese all nestled over a bed of soft spaghetti squash. It’s a perfect combination of flavors and textures — rich, cheesy, and comforting without feeling heavy.
Whether you’re serving this for dinner with the family or bringing it to a gathering, it’s bound to be a hit.
Versatility for Every Preference
One of the best parts about this recipe is how adaptable it is. You can serve it as a traditional casserole over spaghetti squash for a low carb option, or pair it with spiralized zucchini noodles. For those who aren’t watching carbs, pasta works beautifully too. This flexibility makes it a go-to dish for mixed-diet households or when you’re entertaining guests.
A Meal Everyone Will Love
The combination of textures — crunchy chicken, creamy cheese, and tangy sauce — makes this recipe irresistible. And because it’s baked into a casserole, it’s easy to make ahead, reheat, and serve.
This low carb chicken parmesan casserole doesn’t just satisfy cravings — it’s also a healthier alternative without sacrificing flavor. It’s a dish that will have your whole family asking for seconds.
✅ Pro Tip: If spaghetti squash is expensive in your area, you can swap it with zucchini noodles, cauliflower rice, or even a side of roasted vegetables for the perfect low carb meal.
