Ingredients

Scale
  • 1 pound fresh green beans, trimmed and cut into 2-inch pieces
  • 3 tablespoons unsalted butter
  • 8 ounces cremini mushrooms, sliced thin
  • 1 medium yellow onion, finely diced (about 1 cup)
  • 3 cloves garlic, minced
  • 3 tablespoons all-purpose flour
  • 1 cup whole milk
  • ½ cup heavy cream
  • ½ cup low-sodium chicken or vegetable broth
  • 1 teaspoon salt, plus more for blanching water
  • ½ teaspoon freshly ground black pepper
  • 1 teaspoon fresh thyme, chopped (or ½ teaspoon dried)
  • ¼ teaspoon freshly grated nutmeg
  • 3 large shallots, thinly sliced into rings (about 1 cup)
  • 2 tablespoons unsalted butter (for shallots)
  • ¼ teaspoon salt (for shallots)
  • 2 tablespoons fresh parsley, chopped (optional, for garnish)

Instructions

  1. Preheat your oven to 375°F (190°C).
  2. Blanch the green beans: Bring a large pot of salted water to a boil. Add the green beans and cook for exactly 3 minutes until bright green and tender-crisp. Transfer to a bowl of ice water to stop cooking. Drain well and pat dry.
  3. Make the crispy shallots: In a small skillet over medium heat, melt 2 tablespoons butter. Add the sliced shallots in a single layer and cook for 4-5 minutes, stirring occasionally, until golden brown and crispy. Sprinkle with ¼ teaspoon salt and transfer to a paper towel-lined plate.
  4. Cook the mushrooms: In a large skillet over medium-high heat, melt 3 tablespoons butter. Add the sliced mushrooms in a single layer and cook without stirring for 2 minutes. Stir and cook for another 3-4 minutes until browned and liquid has evaporated.
  5. Add the onion and garlic: Add the diced onion and cook for 3 minutes until softened. Add the minced garlic and cook for 30 seconds until fragrant.
  6. Make the roux: Sprinkle the flour over the mushroom mixture and stir constantly for 1-2 minutes until golden and nutty-smelling.
  7. Add the liquids: Slowly pour in the milk, heavy cream, and broth while stirring constantly. Bring to a gentle simmer and cook for 2-3 minutes until thickened to a gravy-like consistency.
  8. Season the sauce: Stir in 1 teaspoon salt, ½ teaspoon black pepper, thyme, and nutmeg. Taste and adjust seasoning if needed.
  9. Combine everything: Add the drained green beans to the skillet and stir gently until every bean is coated in sauce.
  10. Transfer to the baking dish: Pour the green bean mixture into a 9×13-inch baking dish and spread evenly. Sprinkle the crispy shallots on top.
  11. Bake: Place the dish in the preheated oven and bake for 15-18 minutes until bubbly around the edges and the shallots have deepened in color.
  12. Rest and serve: Let the casserole sit for 5 minutes before serving. Garnish with fresh parsley if desired.

Notes

Don’t skip blanching the green beans—it sets the color and ensures they’re tender. Watch the shallots carefully as they go from golden to burnt quickly. Season as you go for the best flavor. For make-ahead, assemble without the shallot topping and refrigerate for up to 2 days; add shallots and bake for 20-25 minutes. Leftovers keep in the fridge for up to 4 days.
