Green Bean Casserole Recipe
We’re all familiar with the age old green bean casserole that combines frozen green beans with cream of mushroom soup. Don’t get me wrong, it tastes great. This recipe however kicks it up a notch by making all the components from scratch. The end result is so much more flavorful and will really impress your guests.
Be sure to keep an eye on the onions for the topping as I burned my first batch.
For the topping:
- 2 medium onions, thinly sliced
- 1/4 cup all-purpose flour
- 1 tablespoons panko bread crumbs
- 1 tablespoon regular unseasoned breadcrumbs
- 1 teaspoon kosher salt
- Nonstick cooking spray
- For beans and sauce:
- 2 tablespoons plus 1 teaspoon kosher salt, divided
- 1 pound fresh green beans, rinsed, trimmed and halved
- 2 tablespoons unsalted butter
- 12 ounces mushrooms, trimmed and cut into 1/2-inch pieces
- 1/2 teaspoon freshly ground black pepper
- 2 cloves garlic, minced
- 2 tablespoons all-purpose flour
- 1 cup chicken broth
- 1 cup half-and-half
Preheat the oven to 475 degrees F.
Use a mandolin to slice the onions very thin, then separate into rings.
Combine the onions, flour, panko and salt in a large mixing bowl and toss to combine. Spray a sheet pan with nonstick cooking spray and evenly spread the onions on the pan. Place the pan on the middle rack of the oven and bake until golden brown, approximately 30 minutes. Toss the onions a few times while they bake. Once done, remove from the oven and set aside until ready to use.
Turn the oven down to 400 degrees F.
While the onions are cooking, prepare the beans. Bring a gallon of water and 2 tablespoons of salt to a boil in an 8-quart saucepan. Add the beans and blanch for 5 minutes. Drain in a colander and immediately plunge the beans into a large bowl of ice water to stop the cooking. Drain and set aside.
Melt the butter in a 12-inch cast iron skillet set over medium-high heat. Add the mushrooms, 1 teaspoon salt and pepper and cook, stirring occasionally, until the mushrooms begin to give up some of their liquid, approximately 4 to 5 minutes. Add the garlic and continue to cook for another 1 to 2 minutes. Sprinkle the flour over the mixture and stir to combine. Cook for 1 minute. Add the broth and simmer for 1 minute. Decrease the heat to medium-low and add the half-and-half. Cook until the mixture thickens, stirring occasionally, approximately 6 to 8 minutes.
Remove from the heat and stir in 1/4 of the onions and all of the green beans. Top with the remaining onions. Place into the oven and bake until bubbly, approximately 15 minutes. Remove and serve immediately.
