You love green bean casserole, but now that you are eating healthier, you realize that the traditional recipe heavily relies on processed foods. This recipe from GE uses fresh green beans, mushrooms, caramelized onions, and panko bread crumbs to heighten the traditional flavors. It just might find a permanent home on your holiday menu.
Ingredients
For the Topping:
- 3/4 cup Panko (Japanese-style breadcrumbs)
- 2 tablespoons butter
- 1/4 teaspoon salt
- 1/8 teaspoon ground black pepper
- 2 medium onions, sliced thinly
For the Beans and Sauce:
- 2 tablespoons salt
- 2 pounds green beans, ends trimmed, and halved
- 3 tablespoons unsalted butter
- 1 pound white button mushrooms, stems removed, wiped clean and broken into 1/2-inch pieces
- 3 cloves garlic, minced (about 1 tablespoon)
- Salt and pepper, to taste
- 3 tablespoons all-purpose flour
- 2 1/2 cups chicken broth
- 3/4 cup heavy cream
Directions
For the Topping: Combine Panko, salt, and pepper in a small bowl and set aside. In a large skillet over medium-high heat, saute onions in 2 tablespoons of unsalted butter for about 10 minutes. Reduce heat to medium-low and sprinkle with salt and cook, stirring occasionally, for about 30 minutes, or until the onions are golden, caramelized, and soft. Combine onions with panko mixture and set aside.
For the Beans and Sauce: Adjust oven rack to middle position and heat oven to 425 degrees.
Fill a large bowl with ice water. Bring 4 quarts of water to a boil in a large pot or Dutch oven. Add 2 tablespoons salt and beans. Cook beans until bright green and crisp-tender, about 6 minutes. Drain beans in colander and plunge immediately into ice water to stop cooking. Spread beans on paper towel-lined baking sheet to drain.
Add butter to now-empty pot and melt over medium-high heat until foaming subsides. Add mushrooms, garlic, 3/4 teaspoon salt, and 1/8 teaspoon pepper; cook until mushrooms release moisture and liquid evaporates, about 6 minutes.
Add flour and cook for 1 minute, 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 3 cups, about 10 minutes. Season with salt and pepper to taste.
Add green beans to sauce and stir until evenly coated. Arrange in an even layer in 3-quart (or 9×13-inch) baking dish. Spread onion mixture over the top. Bake until top is golden brown and sauce is bubbling around edges, about 15 minutes. Serve immediately.
Chef’s Notes
You can prep this ahead of time. Store the Panko topping in an airtight container and combine with the onions just before cooking. Combine the beans and cooled sauce in a baking dish, cover with plastic wrap, and refrigerate for up to 24 hours. To serve, remove the plastic wrap and heat the casserole in a 425-degree oven for 10 minutes, then add the topping and bake as directed.
This recipe can be halved and baked in a 2-quart (or 8-inch square) baking dish. If making a half batch, reduce the cooking time of the sauce in Step 3 to about 6 minutes (1-3/4 cups) and the baking time in Step 4 to 10 minutes.
