Instructions Step-by-Step Southern-Style Green Bean Casserole
1. Preheat Your Oven
Start by preheating your oven to 350°F (175°C). This sets the perfect temperature to ensure even cooking of your casserole.
2. Prepare the Green Beans
Bring a pot of salted water to a boil, then add the trimmed green beans. Blanch them for about 5 minutes until they are bright green and slightly tender. Drain and transfer to an ice bath to stop the cooking process. This helps maintain their vibrant color and crunch!
3. Make the Casserole Mixture
In a large mixing bowl, combine the cream of mushroom soup, milk, and seasonings like garlic and onion powder. Add salt and pepper to bring out the flavors.
4. Combine and Layer
Stir in the blanched green beans and half of the crispy fried onions into the soup mixture. Mix until everything is evenly coated. Transfer the entire mixture into a greased 1.5-quart casserole dish.

5. Bake to Perfection
Place the casserole in the preheated oven and bake for 25-30 minutes, until the mixture is bubbly and heated through. This is where the magic happens!
6. Top with Fried Onions
After the casserole has baked, remove it from the oven and sprinkle the remaining crispy fried onions on top. Return the dish to the oven for an additional 5-10 minutes, or until the onions are golden brown and crispy. This crispy topping adds that perfect crunch everyone loves.

Storing Tips for the Recipe
To enjoy your green bean casserole later, let it cool completely and store it in an airtight container in the refrigerator. It will stay fresh for up to 3-4 days. When reheating, place it back in the oven at 350°F until warmed through to maintain the crispy texture of the onions.
