🦃FAQ
Yes, although the slow cooker time will increase. For fresh green beans, trim them, then cook on low for 4-6 hours or high for 3 hours.
Frozen green beans should be thawed before use. Otherwise, the casserole will be too watery. Once they are thawed, cook them as if they were canned.
The slow cooker is excellent at cooking the casserole but won’t get the onions on top crispy. If you want crispy onions, either bake them in a 400-degree F oven for a few minutes or fry them on the stovetop in butter. Then sprinkle them on top of the casserole right before serving.
