Ingredients

Scale
  • 4 medium zucchinis, grated (drain excess moisture)
  • 1 ½ cups fresh sweet corn kernels (or frozen, thawed)
  • 2 cups shredded sharp cheddar cheese
  • ½ cup grated Parmesan cheese
  • 2 large eggs, beaten
  • ¾ cup whole milk (or 2% milk)
  • 3 tablespoons all-purpose flour
  • 3 tablespoons butter, melted
  • 2 cloves garlic, minced
  • 1 small onion, finely chopped
  • 6 slices bacon, cooked and crumbled
  • Salt and pepper to taste
  • Fresh herbs (optional): chopped parsley or thyme for garnish

Instructions

  1. Preheat your oven to 375°F (190°C).
  2. Grate 4 medium zucchinis using the large holes of your grater. Place the grated zucchini in a clean kitchen towel and squeeze out as much moisture as you can.
  3. In a frying pan over medium heat, cook 6 slices of bacon until crispy. Remove and drain on paper towels, then crumble once cooled. Keep the bacon fat in the pan.
  4. Using the bacon fat, sauté 1 small chopped onion and 2 minced garlic cloves until translucent and fragrant, about 3-4 minutes.
  5. In a large bowl, whisk together 2 beaten large eggs, ¾ cup milk, and 3 tablespoons melted butter.
  6. Stir 3 tablespoons all-purpose flour into the wet mixture until smooth.
  7. Fold in the drained zucchini, 1 ½ cups sweet corn kernels, sautéed onions and garlic, 2 cups shredded sharp cheddar, and ½ cup grated Parmesan. Season generously with salt and pepper.
  8. Pour the mixture into a greased 9×13-inch casserole dish, spreading it out evenly.
  9. Sprinkle the crumbled bacon evenly over the top.
  10. Bake for 35-40 minutes, or until the top is golden and bubbly and a toothpick comes out clean from the center.
  11. Let the casserole sit for 10 minutes before serving to set.

Notes

Squeeze out as much moisture as possible from the grated zucchini to avoid sogginess. Slow cook bacon to render fat for sautéing onions and garlic. If the top browns too fast, cover loosely with foil halfway through baking. Let casserole rest 10 minutes before serving for easier slicing.
