Ingredients

  • pounds green beans rinsed, trimmed and cut into 1-1/2 to 2-inch pieces
  • 1 tablespoon sea salt
  • 6 tablespoons unsalted butter divided
  • 1 large shallot diced (about 1/3 cup)
  • 8 ounces cremini mushrooms sliced
  • 2 cloves garlic minced (about 3/4 teaspoon)
  • 1/4 cup unbleached all-purpose flour
  • 2 cups half & half
  • 1/3 cup freshly grated parmesan cheese
  • 1 teaspoon kosher salt or to taste
  • 1/2 teaspoon freshly ground black pepper
  • 1/8 teaspoon grated fresh nutmeg
  • 1 recipe air fryer beer battered onion rings lightly battered version

Instructions

  • Preheat your oven to 350℉ (or 180℃) and spray a 9 x 9 baking dish with olive oil spray. Fill a large bowl with ice water and place a colander inside.
  • Fill a 12-inch, deep-sided skillet with water half way. Bring to a boil and stir in 1 tablespoon of sea salt. Add in the green beans and simmer for 4 to 6 minute or until slightly tender. Use a slotted spoon to transfer the blanched green beans to the colander in the ice bath, discarding the remaining water in the pan. Once the green beans are cold, remove the colander and drain the beans.
  • In the same skillet, melt 2 tablespoons of butter over medium-low heat. Add the shallots and a pinch of kosher salt. Stir, cooking until soft. About 5 minutes.
  • Next add in the mushrooms, stir and cook until tender. About 5 to 8 minutes. Add in the minced garlic, stir and cook for 1 to 2 minutes. Then add in 4 tablespoons of butter.
  • Once the butter has melted, sprinkle the flour over top, stir and cook for 2 to 3 minutes. Stir while pouring in the half and half, scraping any browned bits off of the bottom of the skillet. Increase the heat to medium-high, stirring constantly until thickened to a creamy soup consistency.
  • Remove off of the heat and stir in the parmesan cheese. Season with the nutmeg, kosher salt and freshly ground black pepper. Add the green beans to the mushroom sauce and toss to coat.
  • Transfer green bean mixture to the prepared baking dish, cover with aluminum foil and bake on the middle rack of your preheated oven for 20 minutes.
  • Remove the foil and scatter the fried onions over top. Place back into your oven for 20 more minutes or until the onion are crisp and the casserole is bubbling.

Notes

If making in advance. Prep the onion rings and the casserole and store separately. Remove 30 minutes prior to baking, and follow the remainder of the instructions. Baking until bubbly and the onion rings are golden brown.
