How to Make Ultimate Green Bean Casserole
Ingredients:
- 2 lbs of fresh green beans (trimmed)
- 3 tablespoons of unsalted butter

Directions:
- Preheat oven to 350°F.

- In a large bowl, stir together the soup, half and half, black pepper, soy sauce, and thyme sprigs.
- Combine the soup mixture, mushrooms, ½ cup of crunchy onions, and green beans together. Transfer the mixture to a large casserole dish. Cover with foil and bake for 20 minutes.
- Remove the foil, top with remaining onions, and bake for an additional 5-10 minutes or until bubbly and golden brown.
