A textural masterpiece that transforms the classic holiday side dish with a homemade roux-based sauce and deeply caramelized, crispy shallots. This recipe ensures vibrant green beans and a golden-brown topping that stays crisp, avoiding the soggy texture of traditional casseroles.

Ingredients

Scale
  • 1.5 lbs fresh green beans, trimmed and cut into 2-inch pieces
  • 3 medium shallots, thinly sliced
  • 3 tablespoons unsalted butter, softened
  • 3 tablespoons all-purpose flour
  • 1 cup whole milk
  • 1 cup low-sodium chicken broth
  • 1 teaspoon Dijon mustard
  • ½ teaspoon garlic powder
  • ½ teaspoon salt (plus more to taste)
  • Black pepper to taste
  • 1 tablespoon olive oil or avocado oil

Instructions

  1. Preheat oven to 400°F (200°C) and grease a 9×13 inch baking dish.
  2. Toss sliced shallots with olive oil, salt, and pepper on a rimmed baking sheet. Roast for 15-20 minutes until golden brown and crispy, then set aside.
  3. While shallots roast, blanch green beans in boiling salted water for 3-4 minutes until crisp-tender. Transfer to an ice bath, drain, and pat dry.
  4. In a medium saucepan over medium heat, melt butter. Whisk in flour and cook for 1-2 minutes until light blonde.
  5. Slowly whisk in chicken broth and milk. Simmer for 3-5 minutes until thickened. Stir in Dijon mustard, garlic powder, salt, and pepper.
  6. Pour the sauce over the blanched green beans in the prepared baking dish and stir to coat evenly.
  7. Sprinkle the roasted crispy shallots evenly over the top.
  8. Bake for 15-20 minutes until the sauce is bubbling and the top is golden.
  9. Let rest for 5 minutes before serving.

Notes

For the best texture, use fresh green beans. If using frozen, thaw and squeeze dry thoroughly. Do not crowd the shallots on the baking sheet to ensure they crisp up. For a gluten-free version, swap all-purpose flour for a 1:1 gluten-free blend. Store leftovers in an airtight container in the refrigerator for up to 3 days; reheat in the oven to restore crispiness.
