Green Bean Casserole

A fresh, home-grown twist on the classic Thanksgiving green bean casserole. Crisp garden green beans are folded into a creamy, from-scratch mushroom and herb sauce, then topped with crispy onions (or homemade herb breadcrumbs) and baked until golden and bubbling. It’s seasonal, comforting, and the perfect way to showcase your fall harvest at the holiday table.
