Ingredients for Slow Cooker Green Bean Casserole

GREEN BEANS: Use Frozen green beans or canned (and drained). If using fresh green beans, boil them for 4 minutes and the cool them in ice water.

SAUCE: Condensed cream of mushroom soup makes this dish super easy, but you could also use any ‘cream of soup’ like celery, potato, or chicken.

TOPPING: Crispy fried onions add a little salty crunch to this recipe, but you can also sprinkle on some seasoned bread crumbs or crushed pork rinds for a lower-carb dish.

VARIATIONS: We love an addition of cooked and crumbled bacon or a handful of shredded cheddar cheese for extra flavor!
