The first layer visible beneath the crumb is rich melted cheese with a smooth, gooey texture and light yellow color, stretching slightly from the spoon. Below the cheese, pieces of browned chicken with slightly crispy edges add texture, accompanied by some orange-colored sauce or cooked vegetables peeking through. The crumb topping looks crunchy and crumbly with different shades of light golden brown. The background shows the casserole in a white dish on a white marbled textured surface, slightly blurred to keep focus on the spoon. Photo taken with an iphone --ar 4:5 --v 7

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: Stir in the Italian seasoning, marinara sauce, almond flour, and chicken. Combine well and cook for 5 minutes to meld the flavors.
Step 4: Spray a 9” x 13” casserole dish with non-stick cooking spray, then pour in the chicken and sauce mixture, spreading evenly.
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, until the casserole is heated through and the cheese is melted and golden.
Step 7: Remove from the oven and let the casserole cool for a few minutes before serving.

Tips & Variations

Use leftover cooked chicken or a rotisserie chicken for convenience.
For extra flavor, sprinkle some fresh basil or parsley on top before serving.
If you prefer, substitute pork rinds for parmesan crisps to add a different crunch.
Add a pinch of red pepper flakes to the sauce for a subtle kick.

Storage

Store leftover casserole in an airtight container in the refrigerator for up to 4 days. Reheat in the oven or microwave until warmed through. For longer storage, freeze portions for up to 2 months and thaw in the refrigerator overnight before reheating.

How to Serve

The dish looks warm and cheesy, with some black specks of seasoning on the cheese. The background shows more of the same dish blurred out, placed on a white marbled surface.
