Ingredients

Crispy onions:

  • ½ cup onion chopped
  • 1 tablespoon olive oil or other vegetable oil
  • 1 tablespoon unsalted butter

Green bean casserole:

  • 3 cups green beans cut into 1-inch pieces
  • 1 cup white cheddar cheese grated
  • 1 tablespoon soy sauce or Worcestershire sauce
  • ½ teaspoon garlic powder
  • 1 cup milk
  • 2 tablespoons all-purpose flour
  • 2 tablespoons butter
  • ¼ teaspoon salt
  • ¼ teaspoon black pepper
  • Pinch of nutmeg ground

Instructions

Crispy onions from scratch:

  • Have ½ cup onion in thin slices. Heat 1 tablespoon olive oil and 1 tablespoon unsalted butter in a large skillet over medium-high heat.
  • Add the onions. Salt them lightly to taste, and make sure they're spread out. Cook until browned but not burned. Move them around a few times so they brown evenly, but don't touch them too much. Blot on several layers of paper towels.

For the green bean casserole:

  • Preheat the oven to 375°F (190°C).
  • Cook 3 cups green beans in a large pot with abundant salted water until al dente (crisp and tender, not too soft). Drain under cold water and reserve. You can put them in a large bowl of ice water to help maintain the green color. 
  • Melt 2 tablespoons butter in a large skillet. Sprinkle 2 tablespoons all-purpose flour and stir with a whisk until well integrated. Cook for 2 minutes, stirring constantly until you have a shiny, lightly colored paste.
  • Slowly pour 1 cup milk while you stir constantly over medium heat. It's important to incorporate the milk as you add it. If lumps form, break them up with a spatula. You need a smooth, lump-free sauce. 
  • Add ¼ teaspoon salt, ¼ teaspoon black pepper, ½ teaspoon garlic powder and pinch of ground nutmeg. Mix well. 
  • Place green beans, ⅔ cup grated cheddar cheese, and half the fried onions in a bowl.
  • Add the white sauce to the green bean mixture and toss to mix with a spatula.
  • Transfer to an 8-inch inch baking dish. Bake for 10 minutes.
  • Add the remaining ⅓ cup grated cheese on top and bake for 10 more minutes. Top with the remaining half of crispy onions and bake for 10 more minutes, until crisp and golden brown. 
  • Serve immediately.
  • Refrigerate leftovers, covered, in the refrigerator. Reheat before eating. 

Notes

Make in advance: assemble and refrigerate, covered, until ready to bake. When it's time to serve, pop it in a preheated oven and bake until golden. 
Spicy: add chili pepper flakes, chili powder or smoked paprika to the white sauce. 
Creamier and richer: use half the amount of cream and substitute the rest for cream.
