how to make Green Bean Casserole
Ingredients :
- Kosher salt
 - 3 lb. green beans, trimmed
 - 12 Tbsp. (1 1/2 sticks) unsalted butter, divided
 - 2 yellow onions, thinly sliced
 - 1 lb. cremini mushrooms, sliced
 - Freshly ground black pepper
 - 4 cloves garlic, finely chopped
 - 1/2 cup (60 g.) all-purpose flour
 - 6 cups whole milk
 - 1 1/2 cups French’s fried onions
 
Directions :
- Preheat your oven to 350°F (175°C).
 - Prepare an ice bath in a large bowl.
 - In a large pot, bring generously salted water to a boil. Add the green beans and cook for 2 to 3 minutes, stirring occasionally, until they are bright green.
 - Use a slotted spoon or tongs to take the beans out and place them in the ice bath to cool. Once cooled, drain the beans and transfer them to another large bowl.
 - In another large pot or saucepan over medium heat, melt 4 tablespoons of butter. Add the sliced onions and a big pinch of salt. Cook and stir occasionally for about 7 minutes, until they start to soften.
 - Add the mushrooms to the pot and cook, stirring often, until the mushrooms are browned, about 7 minutes more.
 - Add the finely chopped garlic and cook for another minute, stirring until fragrant. Season with salt and pepper. Transfer the onion mixture to the bowl with the green beans.
 - In the same pot over medium heat, melt the remaining 8 tablespoons of butter. Add the flour and cook, whisking frequently, until it turns golden and smells toasty, about 3 minutes.
 - Gradually whisk in the whole milk, and season with salt and pepper. Bring it to a simmer and cook, stirring occasionally, until the mixture thickens, about 4 minutes.
 - Pour the thickened sauce into the bowl with the green beans and stir everything together.
 - Transfer the mixture to a 13 by 9 inch baking dish. Bake in the preheated oven for about 30 minutes, until it is warmed through and bubbling.
 - Top the casserole with fried onions and continue to bake for an additional 5 minutes, until the onions are crispy and warmed through.
