Instructions

  1. Preheat the oven to 375°F
  2. Add the chicken, zucchini, spinach, tomatoes, sun-dried tomatoes, shallot, garlic, olive oil, oregano, basil, garlic powder, salt, black pepper, paprika, and red pepper flakes to a 2.5-quart (11×7-inch baking dish).
  3. Toss everything together until well coated in the seasonings.
  4. Sprinkle the mozzarella and Parmesan evenly over the top.
  5. Cover the baking dish with aluminum foil and bake for 20 minutes
  6. Remove the foil and bake uncovered for another 10 minutes.
  7. Broil on high for 1 to 2 minutes, watching closely, until the cheese is golden. Check every 20 seconds to avoid burning.
  8. Sprinkle parsley over the top before serving.
  9. Optional: Add a pinch of oregano, black pepper, and red pepper flakes for extra seasoning.

Notes

  • Use oil-packed sun-dried tomatoes for the best flavor and texture.
  • If using boneless chicken thighs, trim the fat and cube the same way.
  • This recipe is naturally low in carbs and doesn’t need pasta or rice to feel complete.
  • For a make-ahead option, assemble up to the cheese layer and refrigerate until ready to bake. Add a few minutes to baking time if starting cold.
