The Best Green Bean Casserole Recipes

Steps:

• Make the casserole: Place the dried shiitake mushrooms in a small bowl and cover with boiling water, about 2 cups, and cover with plastic wrap. Let steep for 20 minutes. Strain through a fine mesh strainer, reserve 1/2 cup of the liquid and slice the steeped mushrooms.
• Melt the butter in a large Dutch oven over medium heat. Add the diced onion; cook, stirring, until softened, 7 to 10 minutes. Add the cremini and shiitake mushrooms; saute until softened and most of the liquid has evaporated, 10 minutes. Sprinkle in the flour; cook, stirring, 1 minute. Add the broth and mushroom liquid. Bring to a boil, then reduce the heat to medium-low and simmer until thickened, 5 to 10 minutes.
• Bring a pot of salted water to a boil. Add the green beans and cook until crisp-tender, 7 to 10 minutes. Drain; shake off any excess water and add to the mushroom sauce. Cook, stirring occasionally, until the beans are very tender and the sauce is thick, 10 to 12 minutes. Stir in the heavy cream and season with 2 teaspoons of salt and pepper.
• For the topping: Soak the sliced onions in the buttermilk, 5 minutes. Combine the flour and 1 teaspoon salt in a medium bowl. Heat 2 to 3 inches vegetable oil in a large pot until a deep-fry thermometer registers 350 degrees F. Working in batches, drain the onion, toss with the flour and shake off the excess, then fry until golden, 4 to 6 minutes. Drain on paper towels.
• Transfer the green bean mixture to a 4-quart baking dish and top with the fried onions. (The casserole and topping can be made up to 2 hours ahead; refrigerate the casserole. Bring to room temperature; reheat at 350 degrees F, 30 minutes. Top with the fried onion; bake 5 more minutes.)

Steps:

• Preheat the oven to 400˚F (200˚C).
• In a large pot of salted boiling water, blanch the green beans for 3 minutes, until tender and bright green. Drain and transfer to a 9x13-inch (23x33 cm) baking dish.
• Melt 4 tablespoons of butter in a large pan over high heat. Add the onions and cook for 8 minutes, until softened and translucent.
• Add the mushrooms and cook for 5 minutes, until browned. Add the garlic and cook just until fragrant, about 1 minute.
• Transfer the vegetable mixture to the casserole dish with the green beans. Wipe out the pan.
• Melt the remaining 4 tablespoons of butter in the same pan. Add the flour and stir to combine. Cook until a golden brown roux forms, for 5 minutes.
• Add the milk, heavy cream, salt, pepper, chicken broth, and Parmesan cheese, and stir to combine. Reduce the heat to medium-low and cook until the sauce is thickened, about 10 minutes.
• Pour the sauce evenly over the vegetables in the casserole dish and toss until everything is well coated. Cover with foil.
• Bake for 20 minutes, then remove the foil and bake for another 10 minutes.
• Top the casserole with the fried onions, then serve.
• Enjoy!

Steps:

• Preheat oven to 350 degrees F (175 degrees C).
• Place green beans and soup in a large microwave-safe bowl. Mix well and heat in the microwave on HIGH until warm (3 to 5 minutes). Stir in 1/2 cup of cheese and heat mixture for another 2 to 3 minutes. Transfer green bean mixture to a casserole dish and sprinkle with French fried onions and remaining cheese.
• Bake in a preheated 350 degrees F (175 degrees C) oven until the cheese melts and the onions just begin to brown.

Steps:

• In a bowl, combine soup, milk, soy sauce and pepper. Gently stir in beans. Spoon half of the mixture into a 13x9-in. baking dish. Sprinkle with half of the onions. Spoon remaining bean mixture over the top. Sprinkle with remaining onions., Bake at 350° until heated through and onions are brown and crispy, 30-35 minutes.
