For the best crispy topping, add the remaining onions during the last 15-20 minutes of cooking.
If using fresh green beans (1.5 lbs), blanch them first until tender-crisp before adding to the slow cooker.
Use a good quality cream of mushroom soup for richness.
Stir all ingredients well to evenly distribute flavors.
Store leftovers in an airtight container in the refrigerator for 3-4 days.
To reheat, warm gently in the microwave or in a covered oven-safe dish at 300ยฐF (150ยฐC) for 20-30 minutes. Broil briefly or add fresh onions for crispness.
For a dairy-free version, use a dairy-free cream of mushroom soup alternative and plant-based milk. Other variations include cream of chicken/celery soup, shredded cheddar cheese, garlic/onion powder, or a dash of hot sauce.
