Soy Free Classic Mushroom Green Bean Casserole

Fresh green beans get blanched until just crisp-tender, then folded into a rich, from-scratch mushroom sauce built on sautéed onion, garlic, and thinly sliced cremini mushrooms for real earthy depth. Butter and a splash of heavy cream give the sauce its silky body, while a touch of nutmeg and black pepper round out the flavor beautifully. Everything gets layered into a baking dish and topped with crispy fried onions, then baked until the edges bubble and the topping turns deep golden brown. It’s comfort-food casserole at its best — tender beans, glossy sauce, and a crunchy finish in every bite. This one is a great fit to bring to your table without worrying about soy-based ingredients sneaking in. Perfect for a holiday spread or a cozy weeknight side, it reheats well and always disappears fast.

Chef's tip
Coconut aminos are sweeter and less salty; taste and adjust the seasoning.
½ tsp black pepper
¼ tsp freshly grated nutmeg

2 ½ cups crispy fried onions (one 6 oz can), divided

Instructions

1
Preheat the oven to 375°F (190°C). Bring a large pot of generously salted water to a boil. Add the green beans and cook for 5 minutes, until bright green and just barely tender but still with a firm bite. Drain in a colander and set aside.
2
Melt the butter in a large skillet over medium heat. Add the onion and cook, stirring occasionally, until softened and translucent, about 5 minutes. Add the garlic and cook, stirring, until fragrant, about 1 minute.
