Equipment

  • Large skillet
  • 9x13 inch baking dish
  • Cutting board
  • Chef's knife
  • Mixing spoon

Ingredients
  

  • 2 lbs boneless, skinless chicken breasts, cut into 1-inch cubes
  • 3 medium zucchini, sliced into 1/4-inch rounds
  • 1 medium onion, chopped
  • 2 cloves garlic, minced
  • 14.5 oz can diced tomatoes, drained
  • 10 oz can cream of mushroom soup (or healthy alternative)
  • 1 cup shredded mozzarella cheese
  • 0.5 cup grated Parmesan cheese
  • 1 tsp Italian seasoning
  • 0.5 tsp salt
  • 0.25 tsp black pepper
  • 2 tbsp olive oil

Instructions
 

  • Preheat your oven to 375°F (190°C).
  • Heat olive oil in a large skillet over medium heat. Add onion and sauté for 5 minutes until softened. Add garlic and cook another minute.
  • Add chicken to the skillet and cook until browned and cooked through.
  • Stir in diced tomatoes, cream of mushroom soup, Italian seasoning, salt, and pepper. Simmer for 5 minutes.
  • Layer half of the zucchini slices in a 9x13 inch baking dish. Top with half the chicken mixture. Repeat layers.
  • Sprinkle mozzarella and Parmesan cheese evenly over the top.
  • Bake for 25–30 minutes, until bubbly and zucchini is tender.
  • Let stand for 5–10 minutes before serving.

Notes

Lightly salt and drain zucchini to avoid excess moisture. Try adding crushed pork rinds or almond flour as a crunchy topping. Use shredded rotisserie or leftover chicken to save time.
