Classic side dish with a twist. Have the same delicious flavor of green beans with half of the prep time. No canned ingredients! Make-ahead friendly.

Love green beans? Try my cheesy green bean casserole, green bean casserole with cream cheese, and green beans and potatoes. Want something different? Try my smothered garlic green beans or Indian style green beans.

Even in a slow cooker, it’s possible to overcook the casserole, turning the green beans mushy. Keep it on low and check for doneness at the 2-hour mark. If you prefer a thicker sauce, whisk in a tablespoon of cornstarch with the milk before adding it to the soup mixture. Add a dash of soy sauce to the soup mixture for a deeper, umami flavor profile. You can assemble everything the night before and refrigerate. Just add an extra 15 minutes to the cook time to account for the cold start.

🍴Storage and reheating suggestions

Store leftover Green Bean Casserole in an airtight container in the fridge for 3-5 days. Heat leftovers in the microwave. This recipe can also be frozen in a tightly covered container for 2-3 months. Thaw in the fridge overnight and then reheat in the oven or microwave.
