How to Make Green Bean Casserole (Step-by-Step)

Step 1: Preheat & Prep

Preheat your oven to 350°F (175°C). Lightly grease a 1.5-quart casserole dish. You can also use an 8×8-inch baking dish if that’s what you have on hand.

Step 2: Mix It All Together

In a large bowl, combine the cream of mushroom soup, milk, soy sauce, green beans, and 2/3 cup of the crispy onions. Stir until everything is well coated.

Step 3: First Bake

Transfer the mixture to your prepared dish. Bake uncovered for 25 minutes, or until hot and bubbling.

Step 4: Add That Crunch

Sprinkle the remaining 2/3 cup of crispy onions over the top. Bake another 5 minutes until golden brown and crunchy.

Step 5: Let It Set

Let the casserole rest for 5 minutes before serving. This helps it thicken slightly and settle.

Make It Your Own Variations & Swap

• Green Beans: Swap in fresh green beans (blanched 4–5 minutes) or frozen (thawed) for extra texture.
• Soup Base: Try cream of celery or cream of chicken for a twist.
• Vegan Option: Use plant-based cream soup and almond milk; top with fried shallots instead of traditional onions.
• Extra Crunch: Add 1/4 cup slivered almonds or panko breadcrumbs on top.

Tips for Success (and Common Mistakes to Avoid)

What Works:

• Don’t overbake or the onions will burn.
• Use thawed beans if going frozen excess water will ruin texture.
• Taste before salting the soup and onions already bring sodium.

What to Avoid:

• Soggy topping always add crispy onions after the first bake.
• Watery mix drain beans well, especially canned ones.
