I'm not sure what it is about green bean casserole that makes it somehow only seem normal at fall and winter holidays (at least that's how I feel). I remember eating it at potlucks every once in awhile, but green bean casserole was never something I ate much growing up. It wasn't until high school that I asked my mom if we could please add green bean casserole to our Thanksgiving meal. I had seen the countless "Who brought the green bean casserole?" commercials and being the advertising junkie that I am, I suddenly began to wonder why no one in my family ever brought the green bean casserole. Where was this delicious looking dish that I'd only had a handful of times?
Of course my mom was happy to add such an easy dish to her Thanksgiving repertoire. It's little effort and big payoff. So, why change up a timeless dish that everyone already loves and make this more complicated version? I don't have a great answer for that, but I liked the idea of having real mushrooms and I also think this spin on the dish looks far more elegant. Sure, it's green bean casserole, but no one would know it if you brought it to a party. They'd take a bite, love it (because it's fantastic) and then realize that it's a dressed up version of an old favorite. I kind of like that about it. It's seems much less "holiday-only" and much more of a dish that is really just a combination of a lot of delicious ingredients. You'll notice it says "Best Ever" on Alton Brown's recipe. That's his wording, not mine. I loved this variation, but now that I've been exposed to a whole new world of GBC I think I may have to try out a few more before awarding that title! (Starting with Paula's...which had even better ratings!)
Enjoy!
Recipe from Alton Brown
Ingredients
For the topping:
2 medium onions, thinly sliced
1/4 cup all-purpose flour
2 tablespoons panko bread crumbs
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
1/4 teaspoon freshly ground nutmeg
2 tablespoons all-purpose flour
1 cup chicken broth
1 cup half-and-half
Directions
Preheat the oven to 475 degrees F.
Combine the onions, flour, panko and salt in a large mixing bowl and toss to combine. Coat 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 2 to 3 times during cooking. 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 nutmeg 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.
