Sheet Pan Green Bean Casserole Recipes

Steps:

• Cook the green beans: In a large pot, bring 6 quarts of water to a boil. Salt the water generously; it should taste like sea water.
• Prepare an ice bath: Fill a large bowl halfway with ice and add some cold water. Place a colander squarely inside the ice bath; the colander will keep you from having to pick the beans out from amongst the ice cubes. Plunge the green beans into the water and cook 2 to 3 minutes. When the beans are cooked, remove them from the hot water with a strainer and transfer them to the colander inside the ice bath. Use a spoon to "swirl" the beans around in the ice bath so they cool quickly. Drain.
• Make the mushroom base: In a 10-inch cast-iron skillet, melt the butter and add the mushrooms. Season with salt and add the mustard and cayenne. Cook until the mushrooms give off most of their liquid, 5 to 8 minutes. Whisk the garlic and flour into the mushrooms. Cook the flour 1 to 2 minutes, stirring constantly so it doesn't stick or burn, and then add the chicken stock. Bring to a simmer and reduce 1 to 2 minutes. Stir in the cream and sour cream and simmer gently. Continue cooking over low heat until the mixture thickens, 5 to 8 minutes. Set aside.
• Preheat the oven to 350 degrees F.
• Fry the onions: Pour the oil into a medium frying pan. Heat to 350 degrees F.
• In a medium bowl, combine the flour and cayenne. Toss the onion rounds in the flour and "shake" off excess by shaking the rounds in a strainer once they have been breaded. Test the oil by dropping in a few slices; they should rise to the surface and fry gradually.
• Prepare a baking sheet fitted with a kitchen towel. Drop a small batch of the onions into the oil and gently "swirl" with a slotted spoon in the oil as they fry; this will help them fry more evenly on all sides. Fry until golden brown, 1 to 2 minutes. Remove from the oil and spread on the baking sheet. Season immediately with salt.
• Bake and serve: When ready to serve, stir the green beans into the mushrooms. Simmer on the stove over low heat for 2 to 3 minutes so the beans and sauce meld together. Add more cream and a splash water if the sauce is too thick. Transfer the skillet to the oven for 8 to 10 minutes to finish heating it and to give the casserole that "baked" effect. Remove from the oven and top with the fried onions. Serve immediately.

Steps:

• Combine green beans, cream of chicken soup, milk, Parmesan cheese, salt, black pepper, and half the can of French-fried onions in a slow cooker.
• Cover and cook on Low for 5 to 6 hours. Top casserole with remaining French-fried onions to serve.

Steps:

• Heat oven to 400 degrees. Coat a 9-by-13 baking dish with nonstick cooking spray. On a rimmed sheet pan lined with parchment paper, toss together green beans, mushrooms, sliced shallots, garlic and olive oil; season with salt and pepper to taste then spread evenly on the pan. Roast until the vegetables brown in spots and soften, about 30 minutes, tossing halfway through. (Alternatively, if you want the green beans extra soft, set them on an unlined sheet pan, add 3 tablespoons water, cover with aluminum foil, and cook until the vegetables are slightly firmer than you want in the end result, about 30 to 45 minutes.)
• Meanwhile, in a large saucepan over medium-low heat, melt the butter, then add the flour. Cook for about 1 to 2 minutes, whisking constantly until it comes together and begins to turn golden in color.
• Add heavy cream and whisk until it starts to thicken, 6 to 8 minutes. Add the Cajun seasoning, onion and garlic powders, chicken base, nutmeg and 1/2 teaspoon pepper. Whisk to combine, then add 1 1/2 cups Parmesan until melted. Taste and adjust seasonings.
• When the green beans are cooked, add them to the saucepan, and toss to coat until mixture is thoroughly heated. Transfer green bean mixture to the baking dish.
• In a medium bowl, combine bread crumbs, fried shallots and the remaining 1/4 cup Parmesan. Spread evenly over the top of the casserole.
• Set the broiler to high, and broil until brown and bubbly (don't walk away!), about 1 to 2 minutes. Serve hot.

Steps:

• Melt the butter in a large skillet over medium heat. Add the onions and cook for 2 minutes. Add the mushrooms and cook until golden, 4 to 5 minutes.
• Stir in the soup and cream and bring to a simmer. Add the Cheddar and season with salt and pepper. Stir in the green beans and toss to coat.
• Butter a 1 1/2-quart baking dish, spoon in the green bean mixture and top with the fried onions. Bake until bubbly, about 30 minutes.

Steps:

• Preheat the oven to 400 degrees F.
• For the crispy shallot topping: Line a plate with paper towels. Put the shallots in a small saucepan and pour in canola or vegetable oil to cover. Put the pan on the stove, turn the heat to medium and cook, stirring occasionally, until the shallots turn a medium brown, about 4 minutes. Drain them in a fine-mesh sieve, reserving the oil for another use, then turn the shallots onto the paper-lined plate and blot with another paper towel. Sprinkle with salt and set aside.
• For the green bean casserole: Fill a large bowl with water and some ice. Bring a large pot of salted water to a boil.
• Plunge the green beans into the boiling water and cook just until crisp-tender, about 5 minutes. Drain, then plunge them into the ice water to stop the cooking. Drain again.
• Butter a shallow 3-quart casserole and set aside.
• Melt the butter in a large skillet. Saute the mushrooms until browned and any liquid they have released has evaporated, about 6 minutes. Add the minced shallots and saute until slightly softened, another 2 minutes. Sprinkle over the flour and continue to saute until the flour coats the mushrooms well and turns golden, another 2 minutes. Slowly pour in the broth while stirring. Stir in the half-and-half and continue to cook, stirring frequently, until the liquid has thickened. Add the partially cooked green beans, then turn the mixture into the prepared casserole.
• Bake until hot and bubbly, about 15 minutes. Sprinkle over the reserved crispy shallots and bake until the shallots are hot and re-crisped, about 5 more minutes. Garnish with fresh parsley or chervil if desired and serve hot.

Steps:

• Preheat oven to 325 degrees F (165 degrees C). Grease a 2 quart casserole dish.
• In a mixing bowl, combine mushroom soup, milk, cheddar cheese, and half of the onions. Mix together.
• Layer the bottom of a 2 quart casserole dish with 1/2 of the green beans. Pour half of the soup mixture over beans, and add half of the processed cheese. Repeat layering, and top with remaining onions.
• Bake for 30 to 40 minutes.
