I love making green bean casserole because it’s such a comforting and classic dish. The recipe is incredibly simple yet packed with flavor. To start, I preheat my oven to 350°F (175°C) and then mix together green beans, cream of mushroom soup, milk, and a bit of black pepper. After combining everything, I transfer it to a greased baking dish and bake it for about 25 minutes. The final touch is adding a generous layer of fried onions on top and baking it for another 5-10 minutes until it’s bubbly and golden. This process takes about 35-40 minutes in total, including prep and cook time. It serves 4-6 people, making it perfect for family dinners or gatherings. I find that this dish never fails to impress and is always a hit with everyone around the table.
