Ingredients

4 cups cubed rotisserie chicken (or cooked chicken breast, cubed)
3/4 cup no added sugar marinara sauce
1 tbsp Italian seasoning
2 garlic cloves, minced
1 tbsp olive oil
2 tbsp almond flour
3/4 cup parmesan cheese, grated
1 1/2 cups shredded mozzarella cheese
3/4 cup finely crushed parmesan crisps (or pork rinds)
Non-stick cooking spray

Instructions

Step 1: Preheat your oven to 350°F (175°C).
Step 2: In a large skillet, heat the olive oil over medium heat. Add the minced garlic and sauté until fragrant, about 1 minute.
Step 3: Stir in the Italian seasoning, marinara sauce, almond flour, and cubed chicken. Cook the mixture for 5 minutes, allowing the flavors to combine.
Step 4: Spray a 9” x 13” casserole dish with non-stick cooking spray. Pour the chicken and marinara mixture evenly into the dish.
Step 5: Layer the grated parmesan cheese, shredded mozzarella, and crushed parmesan crisps evenly on top of the chicken mixture.
Step 6: Bake in the preheated oven for 25-30 minutes, until the casserole is heated through and the cheese is melted and bubbly.
Step 7: Remove the casserole from the oven and let it cool for a few minutes before serving.

Tips & Variations

Use store-bought shredded rotisserie chicken to save time without sacrificing flavor.
Substitute pork rinds for parmesan crisps if preferred; both add a satisfying crunch.
For extra flavor, sprinkle some fresh basil or chopped parsley on top before serving.
If you want a richer taste, mix in a bit of cream cheese with the chicken mixture.

Storage

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave or oven until warmed through. This casserole can also be frozen for up to 1 month; thaw overnight in the fridge before reheating.
