Green Bean Casserole
 
  • 1 Tablespoon + 1 teaspoon salt, divided
  • 1 pound fresh green beans, rinsed, ends trimmed, and halved
  • 2 Tablespoons (28g) unsalted butter
  • 8 ounces sliced mushrooms
  • 1/2 teaspoon ground black pepper
  • 2 cloves garlic, minced
  • 2 Tablespoons (15g) all-purpose flour
  • 3/4 cup (180ml) chicken or vegetable broth
  • 1 and 1/4 cups (300ml) half-and-half

Instructions

  1. Preheat oven to 450°F (232°C). Line a baking sheet with parchment paper.
  2. For onions: Thinly slice onion and separate into rings. Arrange flour, beaten egg with milk, and panko mixed with salt and pepper in three separate bowls.
  3. Dip onion slices first in flour, then egg mixture, then coat with panko. Arrange on baking sheet.
  4. Bake onions for 20 minutes, flipping twice, until golden brown. Set aside and reduce oven to 400°F (204°C).
  5. Blanch green beans: Boil in salted water for 5 minutes, then immediately transfer to ice water. Drain well.
  6. In an ovenproof skillet, melt butter over medium-high heat. Add mushrooms, salt, and pepper, cooking for 5 minutes.
  7. Add garlic and cook 2 more minutes. Sprinkle with flour and stir to combine.
  8. Add broth and simmer for 3 minutes. Reduce heat to medium-low, add half-and-half, and cook until thickened, about 10 minutes.
  9. Remove from heat. Stir in one-quarter of the onions and all green beans.
  10. Top with remaining onions and bake for 15 minutes until bubbling. Serve warm.
