Prepare for a symphony of textures and tastes. You'll find tender, vibrant green beans and earthy mushrooms swimming in a velvety smooth, savory sauce, brightened by a hint of dry white wine and aromatic thyme. The combination of unsweetened non-dairy milk and full-fat coconut milk creates an incredibly rich and satisfying creaminess. Each bite is a warm embrace, perfectly balanced by the irresistible crunch of golden French fried onions on top. It's a comforting, hearty side dish that feels both familiar and special, sure to be a crowd-pleaser for its rich, umami depth.
While delicious as is, this Classic Vegan Green Bean Casserole is also wonderfully adaptable. You could swap white button mushrooms for cremini for an even deeper, earthier flavor. Feel free to experiment with different unflavored and unsweetened non-dairy milks, though oat or soy milk tend to be excellent choices for creaminess. If you're out of French fried onions, try a crispy breadcrumb topping or toasted pecans for a similar textural contrast.
