Ingredients

  • 2 teaspoons butter or vegan butter
  • 6-7 cups canned or frozen cut green beans (if using fresh green beans, blanch in boiling water first)
  • 1 tablespoon olive oil
  • 1 large onion, finely diced
  • 3 cloves garlic, finely minced
  • 3/4 teaspoon dried thyme
  • 3 tablespoons butter or vegan butter
  • 2 tablespoons all purpose flour
  • a pinch of ground nutmeg
  • salt and black pepper (to taste)
  • 1/2 cup dry white wine
  • 1 cup half and half cream use oat cream for vegan option
  • 1/2 cup water
  • 1 1/2 cups crispy fried onions (the French's brand is free of animal products)

Instructions

  1. Preheat your oven to 325 degrees Fahrenheit and grease a 9-inch by 9-inch baking dish (or roughly equivalent size) with 2 teaspoons butter.

  2. Add the green beans to the baking dish and set aside.

  3. Heat a large saucepan over medium heat and add the olive oil, onions, garlic, and thyme. Saute until the mixture is fragrant and the onions are very soft.

  4. Add the butter and when it's melted, add the all purpose flour and whisk until the mixture becomes thick. 

  5. Add the white wine and continue whisking until the liquid evaporates, about 3 minutes.

  6. Add the cream (or oat cream) and water and stir to combine.

  7. Turn the heat to low and stir the mixture regularly until a thick sauce forms (this will take a few minutes).

  8. Pour the sauce over the green beans in the baking dish and toss gently, just to make sure the sauce is evenly distributed.

  9. Smooth out the top and sprinkle the crispy fried onions over the top.

  10. Bake at 325 degrees until the sauce is bubbly and the top is golden brown (about 20 minutes).

Recipe Notes

This recipe can be made non-vegan (with regular butter and half and half cream) or vegan (with vegan butter or Oat Cream). Your choice!

Replace the white wine with vegetable stock, if desired.
