Fresh Green Bean Casserole
Made from scratch, this green bean casserole recipe is a levelled up version of the classic. Fresh beans, creamy mushroom sauce (not a soup can in sight!) and crispy onions make this a truly delicious side dish recipe, any time of the year.
Many people have grown up with the classic green bean casserole made with a can of Campbell’s mushroom soup. There’s nothing wrong with a nostalgic recipe but this version made with homemade mushroom sauce is just so much better. Using fresh green beans also amps up the flavor and topping the casserole with a mixture of crispy onions (I use packaged but you can make them yourself) and panko bread crumbs makes the whole thing so much more irresistible.
