Soy Free Classic Green Bean Casserole

Cook time45 min

Crisp-tender green beans get folded into a rich, from-scratch mushroom sauce, built by sautéing golden cremini mushrooms and garlic before whisking in broth and cream until velvety and thick. A touch of warm nutmeg and black pepper rounds out the flavor, giving the sauce real depth without relying on anything canned or premade. The whole thing gets layered into a baking dish and finished with a generous scatter of crispy fried onions, then baked until the top turns deep golden and the sauce bubbles at the edges. It’s the kind of homestyle side that feels nostalgic but tastes noticeably fresher than the classic version, with a creamy interior and that essential crunchy top layer intact. This casserole is a solid pick for a soy free table, easy to make ahead and just as comforting reheated the next day.
