Main Ingredients

  • 1 ½ lb green beans trimmed and halved
  • 2 large yellow onions thinly sliced
  • ¼ cup all purpose flour for the onions
  • 2 tbsp panko breadcrumbs for the onion coating
  • ¼ tsp kosher salt for the onions
  • ¼ tsp black pepper for the onions
  • 4 cup vegetable oil for deep frying
  • 3 tbsp unsalted butter for the sauce
  • 12 oz mushrooms chopped into 1/3 inch pieces
  • ½ tsp kosher salt for the sauce
  • ¼ tsp black pepper for the sauce
  • 2 cloves garlic minced
  • 3 tbsp all purpose flour for the sauce
  • 1 ½ cup low sodium vegetable or chicken broth
  • ½ cup heavy cream
  • 1 pinch nutmeg

Instructions
 

Cooking

  • Blanch the beans. Boil in salted water 4 to 5 minutes, then cool in ice water and drain well.
  • Fry the onions. Coat the onions in the flour mixture and fry in 350 degrees F oil in batches for 2 to 3 minutes until golden. Drain on paper towels.
  • Build the sauce. Brown the mushrooms in butter, add the garlic, stir in 3 tablespoons of flour, then whisk in the broth and cream with the nutmeg until thick.
  • Assemble and bake. Mix the beans with the sauce in a baking dish, top with the onions, and bake at 350 degrees F for about 25 minutes until bubbly.

Notes

Substitutions: Frozen green beans work if thawed and patted dry. Half and half can replace the cream.
Tips: Dry the beans well and hold the oil near 350 degrees F.
Storage: Refrigerate up to 3 days. Do not freeze. Reheat to 165 degrees F.
