Green Bean Casserole with Corn Flake Crust
Tender French green beans, savory sour cream sauce, Swiss cheese, and crispy corn flake coating make this the best green bean casserole ever!
- 3 cans French Style green beans drain liquid
- 4 TB butter divided
- 1/2 cup chopped onion
- 2 TB flour
- 1/2 tsp pepper
- 1 TB sugar
- 1 cup sour cream

Sour Cream Sauce
In a large saucepan, melt 1 TB butter.
Add the chopped onions and sauté on low heat until they are soft.
Add 2 TB flour, 1 TB sugar, 1 tsp. salt, and ½ tsp. black pepper. Stir until it forms a smooth paste.
Add 1 cup of sour cream. Stir until it is smooth and bubbly.
Add the drained green beans and gently stir them in.
Assembling the Casserole
Scoop the green bean mixture into an oven-safe baking dish.
Melt the remaining 2 TB butter in a 2 cup glass measuring cup. Add the cup of cornflake crumbs and stir together.
Top the green beans with the cup of Swiss cheese.
Spread the buttery cornflake crumbs on top of the Swiss Cheese.
Bake at 350 degrees for 20 to 30 minutes, until heated through and browned on top.
Let rest for about 10 to 15 minutes.
Notes on Swiss Green Bean Casserole
Salt: I use a combination of salted green beans and unsalted green beans. If you are watching salt, you can use all unsalted green beans. The original recipe called for more than a tsp. of salt. I used just 1 tsp. and that was plenty.
Flour: I always use gluten-free flour and that works fine. If flour isn’t an issue for you, use any all-purpose flour.
Swiss Cheese: I like to buy a nice one and grate it myself. The recipe calls for one cup, but I actually used about 1 and a half cups. You can use any Swiss cheese you like.
Cornflake crumbs: You can buy these already in crumbs or just make the crumbs yourself from a box of cereal. I did mine in my food processor and made extra to use later. I stored the extra crumbs in mason jars. This will be handy for the holidays.
