This easy crockpot green bean casserole is the ultimate holiday side dish that saves oven space and delivers creamy, savory flavor with a crispy fried onion topping. Set it and forget it for a stress-free, crowd-pleasing comfort food.
For best results, drain canned green beans well to avoid watery casserole. Do not cook on high. Add the second cup of fried onions only at the end to maintain crunch. Leftovers keep in the refrigerator for up to 4 days and can be frozen for up to 3 months.
