Instructions
 

Preparation

  • Preheat oven to 375°F. Lightly grease a 9×9-inch baking dish with olive oil.

Cooking Chicken

  • In a medium bowl, combine oregano, smoked paprika, garlic powder, salt, and pepper. Toss the chicken pieces in the spice mixture until coated.
  • Heat olive oil in a large skillet over medium-high heat. Add seasoned chicken and sear for 3–4 minutes per side until golden. Transfer the chicken to a plate.

Sauté Aromatics

  • In the same skillet, reduce heat to medium. Add onion and sauté for 3 minutes until softened. Add minced garlic and cook for 30 seconds, stirring constantly.
  • Return the seared chicken to the skillet and mix with the onion and garlic.

Custard Mixture

  • In a bowl, whisk together eggs and Greek yogurt until smooth. Season lightly with salt and pepper.

Layering

  • Layer half of the zucchini in the baking dish. Spread half of the chicken mixture over it, pour half of the yogurt mixture, and sprinkle half of the mozzarella and Parmesan on top. Repeat the layering with the remaining ingredients.

Baking

  • Cover with foil and bake for 20 minutes. Remove foil and bake for an additional 10–15 minutes until cheese is melty and golden.
  • Let it rest for 5 minutes before slicing. Garnish with parsley or basil if desired.

Notes

Great for meal prep as it reheats well. For variations, feel free to use different cheeses or add herbs to the custard.
