Yummy Green Bean Casserole

Some sides are sacred. Green bean casserole is one of them, and this is the no-frills version that’s been showing up on Thanksgiving tables since Dorcas Reilly first sketched it out in the Campbell’s test kitchen in 1955. Cream of mushroom soup, green beans, milk, a slug of soy sauce for that umami backbone, and a crown of crispy fried onions. That’s the whole show.

The order of operations matters more than people realize. Reserving half the onions for the last five minutes of baking is the move that separates a great casserole from a soggy one. Stir them all in at the start and they go limp. Save half for the final bake and they shatter into salty, golden shards on top.

The soy sauce is what most home cooks skip and shouldn’t. A teaspoon adds depth the soup alone can’t deliver, and unless you tell anyone, they’ll just notice the casserole tastes better than the one Aunt Linda made.

Kitchen Tips

• Drain the green beans well. Excess liquid in the can turns the sauce thin and the topping limp.
• Use whole milk if you have it. Skim makes the sauce break and look watery as it cools.
• For an extra-crisp top, pop the broiler on for the last minute of baking. Watch it like a hawk, the onions go from gold to burnt fast.
• Make it ahead through the first bake. Topping with onions and finishing in the oven takes 5 minutes when guests arrive.

Variations

• Use frozen French-cut green beans instead of canned for a fresher bite. Blanch them first.
• Stir in 4 ounces of sauteed fresh mushrooms for a deeper, more savory casserole.
• Top with crushed Ritz crackers or panko mixed with melted butter alongside the onions for extra crunch.
