Originally a food network recipe.

Ingredients

  • 1 ½ cups half-and-half
  • 1 ½ cups low-sodium chicken broth
  • 1 cup all-purpose flour
  • 1 cup buttermilk
  • 1 cup panko breadcrumbs
  • 1 large red onion, thinly sliced lengthwise
  • 1 pound white button mushrooms, quartered
  • ½ cup grated parmesan cheese (about 1 ounce)
  • 2 cloves garlic, minced
  • 2 pounds green beans, trimmed and halved
  • 2 tablespoons all-purpose flour
  • 2 tablespoons finely chopped fresh parsley
  • 2 teaspoons fresh thyme
  • 3 tablespoons unsalted butter
  • Kosher salt
  • Pinch of cayenne pepper
  • Vegetable oil, for frying

Directions

Make the topping:

Separate the onion strips and soak in the buttermilk at least 10 minutes. Heat 2 inches of vegetable oil in a large pot or Dutch oven over medium heat until a deep-fry thermometer registers 360 degrees F. Combine the flour, panko, parsley and 1 teaspoon salt in a medium bowl. Working in batches, remove the onion strips from the buttermilk, dip in the flour mixture and fry until golden brown and crisp, about 3 minutes. Transfer to a paper towel-lined plate; season with salt.

Make the casserole:

Bring a large pot of salted water to a boil. Add the green beans; cook until crisp-tender, about 6 minutes. Drain, rinse under cold water and blot dry with paper towels. Preheat the oven to 375 degrees F. Melt the butter in a large pot over medium-high heat. Add the mushrooms, season with salt and cook, stirring occasionally, until lightly browned and tender, about 7 minutes. Add the garlic and thyme; cook 1 minute. Add the flour and stir to coat, 1 minute.

Whisk in the half-and-half, chicken broth, cayenne and ½ teaspoon salt. Bring to a simmer and cook, whisking occasionally, until slightly thickened, about 5 minutes. Stir in the parmesan and green beans. Transfer to a 3-quart baking dish. (You can refrigerate the casserole, covered, for up to 4 hours; keep the topping at room temperature.)

Bake the casserole until bubbling, about 15 minutes. Stir, then sprinkle with the topping; bake until warmed through, 5 more minutes.
