Ingredients

  • 1/2 small yellow onion , diced
  • 2 Tablespoons butter
  • 2 Tablespoons all-purpose flour
  • 1/2 teaspoon salt
  • 1/2 cup milk (I used 1%)
  • 1/2 cup sour cream
  • 2 cans green beans
  • 1 cup swiss cheese
  • 1/2 cup fried onions

Instructions

  • Preheat oven for 400 degrees F.
  • In a skillet, cook onion in butter slightly, for just about a minute.
  • Whisk in the flour and salt. Add milk gradually and cook until thick and bubbly. Remove from heat and stir in sour cream and beans.
  • Spread 1/3 of bean mixture in 1-quart casserole. Sprinkle 1/2 of the swiss cheese over the beans. Repeat layers, ending with the beans. Top with fried onions.
  • Bake for 20 minutes.

Notes

If you need to make more, this recipe can easily be doubled or even tripled and made in a 9x13 pan.
