Ingredients

Scale
  • 1½ pounds fresh green beans, trimmed and halved
  • 4 tablespoons unsalted butter
  • 8 ounces cremini mushrooms, sliced ¼-inch thick
  • 3 cloves garlic, minced
  • 2 tablespoons all-purpose flour
  • 1½ cups whole milk, warmed
  • ½ cup heavy cream
  • ½ teaspoon salt, plus more to taste
  • ¼ teaspoon black pepper
  • ¼ teaspoon nutmeg, freshly grated
  • ½ cup grated Parmesan cheese
  • 3 large shallots, thinly sliced into rings
  • ¼ cup all-purpose flour
  • ½ teaspoon salt
  • ¼ teaspoon paprika
  • ¼ cup vegetable or canola oil, for frying

Instructions

  1. Bring a large pot of salted water to a boil. Add green beans and cook for exactly 2 minutes. Drain and plunge into ice water. Drain well and pat dry.
  2. Toss sliced shallots with ¼ cup flour, ½ teaspoon salt, and paprika until coated. Heat oil in a small skillet over medium heat. Fry shallots in a single layer for 2-3 minutes until golden and crispy. Transfer to paper towels and sprinkle with salt.
  3. In a large skillet, melt butter over medium heat. Swirl until it foams and turns golden brown with a nutty aroma, about 3-4 minutes. Immediately add mushrooms.
  4. Cook mushrooms without stirring for 2 minutes, then stir and cook 2-3 minutes more until golden. Add garlic and cook 30 seconds.
  5. Sprinkle 2 tablespoons flour over mushrooms and stir for 1 minute. Slowly whisk in warm milk, then cream, salt, pepper, and nutmeg. Cook until thickened, about 2 minutes. Stir in Parmesan until melted.
  6. Preheat oven to 375°F. Add blanched green beans to the skillet and stir to coat. Transfer to an 8×8 baking dish. Top with crispy shallots.
  7. Bake for 12-15 minutes until bubbly. Let rest 5 minutes before serving.

Notes

For best results, use fresh green beans and do not skip the ice bath. Watch the brown butter carefully to avoid burning. Crispy shallots can be made up to 3 days ahead and stored in an airtight container at room temperature. To make ahead, assemble casserole without shallots up to 2 days in advance; add shallots before baking.
