Step-by-Step Preparation: How to Make Best Southern Green Bean Casserole
Step 1 – Prepare the green beans
Bring a pot of salted water to a boil. Blanch green beans for 3–4 minutes until bright green and slightly tender. Drain and set aside.
Step 2 – Make the creamy sauce
In a skillet, melt butter over medium heat. Add onions and cook until softened, then stir in garlic. Sprinkle flour over onions and stir to create a roux. Slowly whisk in milk and broth until smooth. Simmer until thickened. Stir in salt, pepper, paprika, and cheese (if using).
Step 3 – Combine casserole
In a casserole dish, mix green beans with the creamy sauce until evenly coated.
Step 4 – Add topping
Sprinkle crispy fried onions evenly over the top.
Step 5 – Bake
Bake at 350°F (175°C) for 25–30 minutes, or until bubbly and golden.
