How to Make the Best Green Bean Casserole

1. Preheat your oven to 350°F (175°C). Gather all your ingredients before starting.
2. In a medium casserole dish, mix the drained green beans, cream of mushroom soup, milk, and half of the French fried onions. Stir until well combined.
3. Place the casserole in the preheated oven. Bake for about 25 minutes, until hot and bubbly around the edges.
4. Remove the casserole and sprinkle the remaining fried onions on top.
5. Return it to the oven for 5 minutes to crisp the topping.
6. Season with salt and pepper to taste. Serve the Green Bean Casserole hot and enjoy.

Tips for the Perfect Green Bean Casserole

• Don’t Overbake: Overcooking can dry out the casserole. Look for bubbling edges as your signal to stop baking.
