Description

A comforting, veggie-packed zucchini cornbread casserole combining grated zucchini, sweet corn, melty cheese, and corn muffin mix into a hearty, golden-baked dish—perfect for summer produce or as a satisfying side.


Ingredients

  • 3½ cups grated and well-drained zucchini
  • 1 white onion, finely chopped
  • 16 oz shredded cheddar cheese, divided
  • 1 cup corn kernels (fresh, canned, or thawed frozen)
  • 1 jalapeño, finely chopped (seeds removed for milder flavor)
  • 2 large eggs
  • 1 tsp garlic powder
  • 1 tsp cumin
  • 1 tsp salt
  • ½ tsp black pepper
  • 1 box (8.5 oz) corn muffin mix

Instructions

  1. Preheat oven to 350°F (175°C). Grease an 8×8-inch baking dish.
  2. In a large bowl, combine grated zucchini, onion, half the cheese, corn, jalapeño, eggs, garlic powder, cumin, salt, and pepper.
  3. Stir in the corn muffin mix gently—stop when just combined.
  4. Transfer mixture to the prepared dish, spreading evenly. Sprinkle remaining cheese on top.
  5. Bake for 50–55 minutes until golden and set in the center.
  6. Let cool for 5–10 minutes before slicing to help it firm up.

Notes

  • Use yellow squash or a mix of squash and zucchini as a variation.
  • Try pepper jack, Gruyère, or a Mexican cheese blend in place of cheddar.
  • Canned, fresh, or frozen corn all work—drain if using canned.
  • For more heat, add cayenne or green chilies; omit jalapeño for milder flavor.
  • Store leftovers in the fridge up to 4 days; reheat covered at 350°F or microwave with damp towel.
  • Freeze individual portions—good for up to 3 months.
