How to Make Southern Green Bean Casserole

Step 1: Preheat, blanch, and prep

I preheat the oven to 375°F (190°C) to get the bake ready.

I blanch the green beans for about 5 minutes, then drain and pat dry.

I set out onion, garlic, and mushrooms so I’m not scrambling later.

Step 2: Sauté onion, garlic, and mushrooms

I melt butter in a large skillet over medium heat.

I add onion and garlic; I cook until they smell sweet, about 3 minutes.

I stir in mushrooms and cook until browned and tender, 5–6 minutes.

Step 3: Make the creamy sauce and fold in green beans

I sprinkle in flour and cook 1 minute to remove raw flavor.

I slowly whisk in milk and broth until the sauce is smooth and thickened.

I season with salt and pepper, then fold in the green beans so they’re well coated.

Step 4: Top, bake, rest, and serve

I transfer the mixture to a baking dish and crown it with crispy fried onions.

I bake at 375°F for about 25 minutes, until bubbling and golden.

I let it rest a few minutes before serving to set the creaminess.

Pro tips for each step in Southern Green Bean Casserole

• Step 1 tip: don’t overcook the beans in blanching; they should stay crisp-tender. Reserve a splash of the blanch water to loosen the sauce if needed.
• Step 2 tip: dry the mushrooms well; they brown better in batches for even flavor.
• Step 3 tip: whisk milk and broth smoothly; if the sauce thickens too fast, add a splash more liquid.
• Step 4 tip: bake uncovered to crisp the onions; rest briefly so the sauce thickens nicely.

Tips for Success

• In Southern Green Bean Casserole, I time steps like clockwork to keep textures perfect. Blanch the beans until crisp-tender, then shock them in ice. Dry well before mixing to avoid a soggy sauce. Bake uncovered so the onions stay crisp and golden.
• For Southern Green Bean Casserole, season thoughtfully; salt gradually and adjust. Taste as you go, then finish with a splash of acid. Pepper helps; cheese is optional for richness.
