Start by gathering the ingredients needed for this recipe.
In a medium bowl, mix cream of mushroom soup, milk, onion, garlic, salt, and pepper.
INGREDIENT SWAP: The key is to use a cream-based soup. Swap the traditional mushroom soup for cream of chicken, cream of asparagus or cream of broccoli.
Next, place the canned green beans into the bottom of the crockpot. Since I am making this green bean casserole for a crowd, I use 4 cans of green beans.
Then, pour the soup mixture on top of green beans and gently stir.
PRO TIP: If you are feeding less than 7 people, half the recipe.
At this point, you can cover the crockpot with foil and place in the fridge to be cooked the next day. On the day of the event, cook on high for 2-4 hours or low for 4-6 hours.
NOTE: If you cook the onions for less than 3 hours they will still have a bit of a crunch to them. Cook longer if you prefer softer onion pieces.
Before serving, sprinkle French fried onions on top for extra crunchiness. We like these gluten-free French Fried Onions Sprouts Farmers Market.
