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 into the dish.
Step 5: Layer the parmesan cheese, mozzarella cheese, and finely crushed parmesan crisps evenly over the top.
Step 6: Bake 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 the casserole cool for a few minutes before serving.

Tips & Variations

For extra flavor, add chopped fresh basil or oregano before baking.
Use cooked ground turkey or beef as a substitute for chicken.
Swap almond flour with coconut flour if preferred, but use less as it absorbs more moisture.
To make it dairy-free, use dairy-free cheese alternatives and nutritional yeast instead of parmesan.

Storage

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

FAQs

Can I use raw chicken instead of cooked chicken?

This recipe works best with cooked chicken to ensure the casserole heats evenly and maintains the right texture. Using raw chicken may result in uneven cooking.
