Notes

  • Slice zucchini and squash uniformly to ensure even cooking and a consistent texture throughout the casserole.
  • Fresh corn kernels work best, but frozen corn can be a convenient substitute when fresh isn’t available.
  • Drain sautéed vegetables thoroughly to prevent excess moisture from making the casserole soggy.
  • For a gluten-free version, swap regular breadcrumbs with gluten-free breadcrumbs or crushed gluten-free crackers.
