A completely fresh green bean casserole that can be made-ahead for your Thanksgiving feast. Once you try this fresh take on this casserole, you'll never go back to the canned type again!
Ingredients
  • ½ cup panko
  • 2 tablespoons olive oil (or melted butter)
  • ¼ teaspoon table salt
  • ⅛ teaspoon ground black pepper
  • 3 cups canned fried onions (about 6 oz.)
  • 2 lbs green beans, ends trimmed and halved
  • 3 tablespoons unsalted butter
  • 1 lb sliced white button mushrooms
  • 3 medium garlic cloves, minced
  • fresh ground black pepper
  • 3 tablespoons unbleached all-purpose flour
  • 1½ cups low sodium chicken broth
  • 1½ cups heavy cream
Instructions
  1. In a small bowl, mix together panko and fried onions with two tablespoons of olive oil (or melted butter). Set aside.
  2. Fill a large bowl with ice water. Bring a large pot of water to a boil. Add two tablespoons of salt and the green beans. Cook beans until bright green and crisp-tender, for about 6 minutes.
  3. Drain beans in colander and plunge into ice water to stop cooking. Set aside.
  4. Add butter to your now-empty pot and melt over medium-high heat until foaming subsides.
  5. Add mushrooms, salt and pepper them.
  6. Add the garlic next. Make sure to watch this so that it doesn’t burn.
  7. Cook this mixture until mushrooms release moisture and liquid evaporates, about 6 minutes.
  8. Add flour and cook for 1 minute, over medium heat, stirring constantly. Stir in broth and bring to simmer, stirring constantly. Add cream, reduce heat to medium, and simmer until sauce is thickened and reduced to 3½ cups, about 12 minutes. Season with salt and pepper to taste.
  9. Add green beans to sauce and stir until evenly coated. Arrange in even layer in 3 quart (or 13 x 9") baking dish.
  10. Store your onion & panko topping in a baggie in your pantry. Freeze in a freezer-safe container or in a foil pan. Allow the casserole to thaw 1-3 days before your event, covered with plastic wrap.
  11. Heat the casserole in a 425 degree oven for 10 minutes. Add the onion topping and bake for an additional 20 minutes. You want to bake this until the top is golden brown and the sauce is bubbling on the edges.
