How to Make this Recipe

Spread evenly into the bottom of the crockpot and cook on high for 1.5 hours or low for 2-3 hours. Top with remaining onions and enjoy!
Substitutions and Additions
- substitute cream of mushroom soup with cream of chicken. Or make it cheesy and try cream of cheddar.
- sprinkle parmesan cheese on top of the casserole with the remaining onions.
- try using french style onions, or frozen green beans for a different taste. (I personally hate frozen green beans, but some like it that way!)
- add bacon bits or diced ham
FAQs
You can. Frozen green beans don’t need to be thawed first- just add a little extra cooking time. Fresh beans need to be blanched for a few minutes before adding to the crockpot to help them stay tender.
Yes. Assemble everything in the crockpot the day before, cover it and refrigerate overnight. When ready just cook as directed.
You can, but I recommend warming in the oven later so that the onions crisp back up. You may also need to add a touch of milk to help make it creamy again.
