đź›’ Ingredients You’ll Need
For the Crispy Chicken:
- 2 lbs chicken breast, cut into bite-sized cubes
- 1 cup almond flour (or crushed pork rinds for extra crunch)
- 2 large eggs, beaten
- 1 cup grated Parmesan cheese
- 1 tsp Italian seasoning
- 1 tsp garlic powder
- ½ tsp salt & ½ tsp black pepper
- 2 tbsp olive oil (for pan-frying)
For the Casserole:
- 2 cups sugar-free marinara sauce (check labels for hidden carbs!)
- 3 cups shredded mozzarella cheese
- ½ cup grated Parmesan (for topping)
- Fresh basil leaves (for garnish)
👩‍🍳 Step-by-Step Instructions (The Classic Recipe)
Step 1: Prep Your Station
Preheat your oven to 400°F (200°C). Grease a 9×13 inch baking dish with olive oil or cooking spray. Set aside.
Step 2: Set Up Your Breading Station
Create three shallow bowls:
- Bowl 1: Beat the 2 eggs
- Bowl 2: Combine almond flour, grated Parmesan, Italian seasoning, garlic powder, salt, and pepper
- Bowl 3: Your cubed chicken
Step 3: Bread the Chicken
Dip each chicken cube first into the egg, then coat thoroughly in the almond flour mixture. Press gently to help the coating adhere.
Step 4: Pan-Fry for Extra Crispiness
Heat olive oil in a large skillet over medium-high heat. Pan-fry the breaded chicken pieces for 2-3 minutes per side until golden brown. (Don’t worry about cooking through — they’ll finish in the oven!)
Step 5: Assemble the Casserole
Spread 1 cup of marinara sauce on the bottom of your baking dish. Arrange the crispy chicken pieces in a single layer. Top with the remaining marinara sauce, then cover generously with mozzarella and Parmesan.
Step 6: Bake to Perfection
Bake uncovered for 20-25 minutes, until the cheese is bubbly and golden and the chicken reaches an internal temperature of 165°F (74°C).
Step 7: Garnish & Serve
Let the casserole rest for 5 minutes before slicing. Top with fresh basil leaves and serve hot!
🍽️ Serving Suggestion: Pair with a side of zucchini noodles, cauliflower rice, or a fresh green salad for a complete low-carb meal.

đź’ˇ Pro Tips for the BEST Results
🔥 Don’t skip the pan-fry step — It creates a crispy crust that holds up in the oven.
🧂 Taste your marinara — Some sugar-free brands are too acidic. Add a pinch of erythritol or stevia if needed.
🧀 Use freshly grated cheese — Pre-shredded cheese contains anti-caking agents that prevent perfect melting.
⏰ Let it rest — Resting for 5 minutes allows the flavors to meld and makes slicing easier.
🌿 Add fresh basil AFTER baking — Adding it before will turn it black and bitter.
