Ingredients
- 4 cans (14.5 ounces each) cut green beans, drained
- 2 cans (10.5 ounces each) condensed cream of mushroom soup
- 1/2 cup milk
- 1/2 teaspoon garlic powder
- 1/4 teaspoon black pepper
- 1 cup shredded cheddar cheese (optional)
- 1 1/2 cups French fried onions, divided
How to Make Crock Pot Green Bean Casserole
Drain the canned green beans and add them to your slow cooker.
In a medium bowl, whisk together the cream of mushroom soup, milk, garlic powder, and black pepper.
Pour the soup mixture over the green beans and stir gently until everything is combined.
If you’re adding cheddar cheese, stir it in now.
Cover and cook on LOW for 3 to 4 hours or HIGH for about 2 hours, until heated through and bubbly around the edges. Cooking times can vary depending on your slow cooker.
Stir in about 1/2 cup of the French fried onions during the last 20 to 30 minutes of cooking.
Sprinkle the remaining French fried onions over the top just before serving.
For the best crunchy topping, wait until you’re ready to serve before adding the final layer of fried onions.
Tips for Making Green Bean Casserole in the Crock Pot
Drain the green beans well. Too much extra liquid can make your casserole watery. Make sure to drain the canned green beans before adding them to the slow cooker.
Use frozen green beans. You can substitute frozen green beans if you prefer. Thaw and drain them before adding them to the Crock Pot.
Don’t add all the fried onions at once. The fried onions soften as they cook. Save most of them for the end so you still get that delicious crunchy topping.
Add cheese for extra flavor. A little shredded cheddar cheese makes this casserole extra creamy and delicious.
Keep it warm for serving. Once the casserole is fully cooked, you can use the warm setting to keep it ready for dinner. Add the crispy onions right before serving.
Can You Make Green Bean Casserole Ahead of Time?
Yes! You can mix together the green beans, cream of mushroom soup, milk, and seasonings the night before. Store the mixture covered in the refrigerator.
When you’re ready to cook, transfer everything to your slow cooker and follow the cooking instructions. You may need a little extra cooking time if the mixture is still cold.
Wait until the end to add the fried onions so they don’t become soggy.
