Ingredients

4 cups cubed rotisserie chicken (or chicken breast, cooked and 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.
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: Add Italian seasoning, marinara sauce, almond flour, and chicken to the skillet. Stir to combine and cook for 5 minutes.
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 parmesan cheese, shredded mozzarella, and finely crushed parmesan crisps 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 from the oven and let cool for a few minutes before serving.

Tips & Variations

For a spicier kick, add red pepper flakes to the sauce mixture before baking.
Use shredded rotisserie chicken for an easy shortcut.
Substitute crushed pork rinds if you prefer a crunchier topping.
Try adding sautéed mushrooms or spinach to the chicken mixture for extra veggies.

Storage

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat gently in the oven or microwave until warmed through to keep the cheese melty and delicious.
