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 (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: Add Italian seasoning, marinara sauce, almond flour, and chicken to the skillet. Stir to combine and cook for 5 minutes, allowing flavors to meld.
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 over the top.
Step 6: Bake in the preheated oven for 25-30 minutes, until the casserole is thoroughly heated and the cheese is melted and bubbly.
Step 7: Remove from the oven and let the casserole cool for a few minutes before serving.

Tips & Variations

Use leftover rotisserie chicken to save time and add extra flavor.
For a spicier kick, add crushed red pepper flakes to the marinara mixture.
Substitute crushed pork rinds for parmesan crisps if preferred or unavailable.
Add fresh basil or parsley on top just before serving for a burst of freshness.

Storage

Store any leftover casserole in an airtight container in the refrigerator for up to 4 days. Reheat portions in the microwave or oven until hot throughout. This dish also freezes well; thaw overnight in the refrigerator before reheating.
