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 grated parmesan cheese
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. Combine well and cook for 5 minutes, allowing the 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 cheese, and finely crushed parmesan crisps evenly over the top.
Step 6: Bake in the preheated oven for 25-30 minutes, or 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

Use rotisserie chicken to save time, or swap with leftover cooked chicken breast.
For extra flavor, add a sprinkle of crushed red pepper flakes to the sauce.
Substitute pork rinds for parmesan crisps if preferred or to vary the crunch.
Fresh basil or parsley sprinkled on top before serving adds a bright, fresh note.

Storage

Store leftover casserole in an airtight container in the refrigerator for up to 4 days. To reheat, warm individual portions in the microwave or oven until heated through. Avoid freezing as the texture of the cheese may change.

FAQs

Can I make this casserole dairy-free?

This recipe relies heavily on cheese for flavor and texture, so making it fully dairy-free would require significant substitutions. You might try using dairy-free cheese alternatives, but the texture and taste will differ.

What can I use instead of almond flour?

If you’re not avoiding carbs, panko breadcrumbs can be a substitute, but this will increase the carb content. Otherwise, you may omit it, but keep in mind the thickening effect might be reduced.
