Instructions

Prepare the Potatoes

Toss sliced potatoes with oil, salt, and pepper, then arrange them in a lightly greased baking dish.

Cook the Chicken Filling

Sauté onions, garlic, and bell peppers in oil until soft. Add the chicken, tomato paste, spices, and diced tomato. Cook until the chicken is fully cooked and well coated in the sauce. Stir in cilantro.

Layer half the potatoes, spread the chicken filling on top, then pour half the béchamel sauce over it. Repeat with the remaining potatoes and sauce.

Add Cheese & Bake

Sprinkle mozzarella cheese over the top and bake at 375°F (190°C) for 25-30 minutes until golden and bubbly.

Let It Rest & Serve

Allow to cool slightly before slicing. Enjoy warm!
