How to Make Southern Green Bean Casserole
-
Boil the Broth: Pour the chicken broth into a saucepan and set it over medium-high heat. Bring it to a rolling boil, which will form the base for your creamy sauce.
-
Mix the Dry Ingredients: In a separate bowl, combine the flour, milk, onion powder, garlic powder, salt, and pepper. Whisk gently until everything is blended smoothly.
-
Combine with Broth: Carefully add the flour mixture to the boiling broth while stirring continuously. This helps prevent any clumps from forming and ensures a silky sauce.
-
Thicken the Sauce: Lower the heat to medium-low and let the mixture cook, stirring occasionally, until it thickens (about 6-10 minutes). Look for a creamy consistency that coats the back of a spoon.
-
Preheat Oven: While the sauce is thickening, preheat your oven to 350°F so it’s ready when it’s time to bake.
-
Blanch the Green Beans: In a pot of boiling water, blanch the fresh or frozen green beans for about 2-3 minutes. They should be bright green and slightly tender. Drain them and quickly rinse in cold water to stop cooking.
-
Heat the Creamy Sauce: Place the creamed soup back on the stove at medium heat. Stir it gently to warm through, preparing it to combine the flavors.
-
Add Cheese and Spices: Mix in 1 cup of grated cheddar cheese, onion powder, garlic powder, salt, and pepper into the creamed soup. Stir until the cheese melts, yielding a creamy, delicious mixture.
-
Combine with Green Beans: Add the blanched green beans to the creamy sauce. Gently fold them in until they are fully coated and well combined.
-
Bake the Casserole: Transfer the mixture to a baking dish and place it in the preheated oven. Bake for 30-35 minutes, or until the filling is bubbling and heavenly.
-
Add Topping: Remove the dish from the oven and sprinkle the fried onions and an additional ½ cup of grated cheddar cheese on top for that perfect golden finish.
-
Final Bake: Return the casserole to the oven and bake for an additional 10 minutes, or until the topping is crisp and golden brown. Let it cool for a few minutes before serving.
Optional: Garnish with fresh herbs for a pop of color and extra flavor.
