Ah! Now it clicks—you’re probably talking about the classic 3-ingredient party casserole that many aunts bring, often called “Green Bean Casserole” (or a variant). The version with cream of mushroom soup is iconic.
Here’s the basic idea:
3-Ingredient Casserole
Ingredients:
- Canned green beans (or any vegetable of choice)
- Cream of mushroom soup
- French fried onions (or a crunchy topping, sometimes English walnuts can substitute for a nutty twist)
Method:
- Preheat oven to 350°F (175°C).
- Mix green beans with cream of mushroom soup in a casserole dish.
- Top with fried onions (or walnuts) and bake 20–25 minutes until bubbly and golden.
This recipe is famous because it’s ridiculously simple, yet always a hit at parties.
If you want, I can also give a version with English walnuts instead of fried onions for a slightly gourmet twist—it still keeps the 3-ingredient rule. Do you want me to do that?
