A nostalgic and comforting green bean casserole featuring crisp-tender green beans, creamy mushroom sauce, and a golden crispy fried onion topping. Perfect for family meals, potlucks, and holiday gatherings.
Do not overcook green beans to keep them crisp-tender. Fry onions slowly over medium heat to avoid burning. Use fresh mushrooms for best flavor and texture. Whisk liquids gradually to prevent lumps in the sauce. Let casserole rest before serving. For extra crunch, reserve some fried onions to sprinkle on top before serving. Can be made ahead and refrigerated or frozen before baking.
