Southern green bean casserole is not the classic green bean casserole with mushroom gravy. No....this one is much tastier. My green bean casserole is a favorite at family meals, potlucks, and any gathering where food is the main deal!
Crisp green beans, gooey Swiss cheese, and cornflake crumbs combine to make this a sweet, savory, and crunchy dish. And it’s a make-ahead recipe that only takes 15 minutes to prep and 45 minutes in the oven.
How do you know it’s a recipe from the South? Sugar. Fat. Cheese. And generally sour cream or mayonnaise. This one has sour cream. (Some have both!) Southern cooks are the best.

Seriously, who wouldn’t love this recipe? Sugar, cheese, and sour cream, combined with French-style green beans and onions to make a deliciously creamy, sweet yet savory casserole.
Easy to make. The recipe calls for only 9 ingredients and is simple to make. Just grate the onions and cheese. Saute the flour, sugar, salt, and onions to make a paste. Add the cheese and sour cream.
Thaw and drain the green beans. And then it’s a simple 3-layer process. All told, 15 minutes of prep. You can make the casserole a few days before your event and just put it in the frig.
Then pop it in the oven with your other sides on the day of your meal, and bake it for just 45 minutes.
Fancy Dish.This special green bean casserole is an elegant dish fit for any family get-together, potluck meal, Thanksgiving, Christmas, or holiday table. Brown and crispy on the top, with bubbling cheese and green beans underneath. Put it in a lovely baking dish and watch people dig in.
Enticing flavor! Sweet, a bit tangy, and pure yum.
What Goes Into The Green Bean Casserole
- green beans
- butter
- flour
- sugar
- onions
- sour cream
- Swiss cheese
- cornflake crumb
The ingredients are generally easy to find. Occasionally, it is hard to find the most delicious ingredient, Kellogg’s Corn Flakes Crumbs. They are sprinkled over the top of the casserole to provide a wonderful, brown topping.
French-style green beans are the best green beans for this recipe. They look fantastic, stay crisp, and are super tasty.
There’s no need to buy fresh beans and cut them. The frozen ones work great.
Swiss Cheese. Swiss cheese has a little tang to it. It melts wonderfully. The flavor blends well with the sour cream and onions, making the cheese mixture super tasty.
Substitutions and Variations
Flour. If you want this recipe to be gluten-free, substitute an equal amount of gluten-free flour for the wheat flour. My favorite gluten-free flour is Bob’s Red Mill 1-to-1 Baking Flour, but any gluten-free flour will work.
Corn Flake Crumbs. If you can’t find Kellogg’s Cornflake Crumbs, make your own using regular cornflakes and simply crush them.
Try Bread Crumbs. If you are allergic to corn, sprinkle breadcrumbs over the casserole instead of the cornflake crumbs.
You can even use Italian-seasoned breadcrumbs as a delicious option. It will create an even deeper flavor burst.
Cheese. Swiss is best, but you can use Gouda, Pecorino Romano, or Parmesan if you prefer.
Beans. If you don’t have French-cut green beans, you can use any style of green bean. If you use fresh beans, you will need to parboil them.
How To Make This Recipe
There are 4 basic steps to making this casserole.
- Prepare the ingredients
- Grate the onion. You want the onions to be tiny pieces. I’m lazy. I do this in my mini food processor.
- Grate the cheese. The cheese does not have to be small. Make it the size you would put on tacos.
- Thaw and pat dry the frozen green beans.
- Make a paste
- Saute butter, flour, sugar, salt, and onions. This will be a thick, gooey mess when finished.
- When it looks like a thick, not-too-wet concoction, add the sour cream and cheese and mix to combine.
- Layer. Make sure the dish is large enough to put the casserole together and leave about ½ inch at the top of the dish. Otherwise, it might overflow when baking. Butter or oil your casserole dish before making three layers consisting of green beans, cheesy paste mixture, and cornflake crumbs.
- Bake and serve. 45 minutes in a 350F degree oven. The top will be nicely browned and the cheese mixture will drip down through the green beans. Serve hot. So amazing!
How To Store This Casserole
If there is any casserole leftover, simply let it cool. Then, cover with plastic wrap and refrigerate for up to one week.
Recipe FAQs
Yes! You can make this green bean casserole up to a week ahead of time, cover it, and refrigerate it. However, wait to put the cornflake crumbs on top until just before you bake it. Just pull it out of the fridge, remove the cover/plastic wrap, sprinkle the cornflake crumbs, and bake at 350F degrees for 45 minutes until done.
Not if you use frozen green beans. When using frozen green beans, you simply thaw, drain, and pat them dry. If you are using fresh green beans, you will need to clean and steam them first.
No, but you might have to bake it for a different length of time. A deeper dish may bake a little slower than a shallow dish, so you will have to keep an eye on it when cooking.
You may need more crumbs for the topping if the top surface is larger. Make sure the entire top of the casserole has a nice, thin layer of cornflake crumbs on it.
