This creamy green bean casserole is a nostalgic, crowd-pleasing side dish made effortlessly in the crockpot. Tender green beans, a rich mushroom sauce, and crispy fried onions make it perfect for parties, holidays, or cozy family dinners.
For gluten-free, use gluten-free soup and fried onions. For dairy-free, substitute coconut yogurt and vegan cheese. If using canned green beans, drain well and reduce cooking time by 30 minutes. For extra flavor, stir in a tablespoon of butter before serving. Garnish with fresh parsley or chives for color.
