green bean casseroleWhoa, best ever? That's a bold claim to make, especially when everyone is frantically scouring the Internet for recipes since Thanksgiving is coming up fast and furious. Still, this supposedly best ever green bean casserole recipe by Alton Brown should helpfully steer you in the right direction. There's nothing that screams Thanksgiving quite like a perfectly cooked, deliciously crunchy green bean casserole, after all (though with this recipe, Thanksgiving might not be the only time you prepare it!).

It seems that some folks had problems getting the onions to bake consistently per the reviews, so instead, you might want to buy some fried onions. You really can't go wrong with drenching green beans in mushrooms, garlic, and nutmeg with crunchy onions on top. Just be sure to wear your sweatpants.

Best Ever Green Bean Casserole by 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.
