Green Bean Mushroom Casserole Recipes

Steps:

• Preheat the oven to 450 degrees F.
• Bring a large pot of salted water to a boil. Add the green beans and cook until they just turn bright green, 2 to 3 minutes. (You don't want to cook the green beans through as they will cook in the oven also.) Strain and plunge the green beans immediately in a large bowl of ice water to stop the cooking process. When cool, drain and set out to dry on paper towels.
• Set a 12-inch cast-iron skillet over medium-high heat. Add the butter and vegetable oil. Once the butter is melted and the pan is hot, add the mushrooms. Cook undisturbed so the mushrooms sear nicely, about 1 minute. Add the thyme and garlic and continue cooking the mushrooms to achieve some nice color. Season with the salt, pepper, cayenne and nutmeg. Cook 2 to 3 more minutes longer, dusting the mushrooms with some of the flour as they release moisture. Stir with a whisk to incorporate the flour (just like making a roux) and gradually add in the chicken stock. Bring to a simmer, then reduce the heat and add the sour cream and cream. Stir gently and cook over low heat until gravy thickens, 5 to 6 minutes. Add the blanched green beans to the pan and fold together so everything is mixed well. Spread out evenly in the pan. Sprinkle the green beans with the grated Parmesan and transfer to a roasting tray (to catch any spill-over). Bake until the casserole is bubbly and the top is melted and golden, 15 minutes.
• Pour the vegetable oil into a deep skillet and heat to 350 degrees F. Pour the flour into a large mixing bowl and sprinkle generously with salt and pepper. Toss the shallot rounds in the seasoned flour, then place in a strainer and shake off any excess flour. Fry the shallots in the hot oil in small batches until golden brown, 3 to 5 minutes. Drain on paper towels and season with salt while still hot.
• Top the green bean casserole with the fried shallots and serve.

Steps:

• Preheat oven to 350 degrees F (175 degrees C).
• In a medium casserole dish mix together green beans, milk, cream of mushroom soup, and 1/2 of the can of onions.
• Bake for 25 minutes in the preheated oven, until heated through and bubbly. Sprinkle remaining onions over the top, and return to the oven for 5 minutes. Season with salt and pepper to taste.

Steps:

• Heat oven to 350°F. In 1 1/2-quart casserole or glass baking dish, mix green beans, soup and milk.
• Bake 20 to 25 minutes, topping with onions during last 5 minutes of baking, until bubbly.
• ALTERNATE METHOD: Heat oven to 325°F. In 1 1/2-quart casserole or glass baking dish, mix green beans, soup and milk. Bake 25 to 30 minutes, topping with onions during last 5 minutes of baking, until bubbly.

Steps:

• Melt the butter in a large skillet over medium heat; add in mushrooms and garlic; cook stirring until mushrooms loose their moisture then set aside.
• Place the green beans in a medium saucepan; cover with chicken broth and bring to a boil; cook for about 8-10 minutes or until just fork-tender drain but do not rinse.

• Place the mushroom soup, onion/mushroom mixture, Parmesan cheese, black pepper and onion rings in a large bowl; mix well to combine, add in the cooked green beans; mix to combine.
• Transfer to the prepared casserole dish.
• Bake in a preheated 350 degrees F oven for 20 minutes.
• Remove from oven and sprinkle the grated cheddar cheese on top; return to oven for about 5-7 minutes or until the cheese has melted.

Steps:

• Make sauce: In a saucepan scald milk and bay leaf. In another saucepan, melt butter over medium heat. Add flour and cook, whisking constantly, 2 minutes.
• Remove bay leaf from milk and slowly pour into butter-flour mixture, whisking constantly. Season, to taste, with mustard, nutmeg, salt and pepper. Cook, stirring occasionally, until thickened, about 5 minutes. Remove from heat and add cheddar, stirring until melted and smooth.
• Heat oven to 350 degrees F. Fold green beans and mushrooms into sauce, then transfer to a buttered casserole. Sprinkle top with Parmesan and buttered bread crumbs. Bake 50 minutes, or until casserole is bubbly and topping is lightly browned.

Steps:

• Sauté chopped garlic in the butter and olive oil, add mushrooms until mostly soft.
• Set aside to cool.

Steps:

• Over high heat, bring pot of salted water to boil. Add beans. Cover; cook 4-5 minutes. Coat 2-quart baking dish with cooking spray. Drain beans; reserve. Preheat oven to 375 degrees.
• In large skillet, melt 1 T. butter over medium heat. Add onions; cook, stirring, 3-4 minutes. Add mushrooms; cook, stirring, until softened, 1-2 minutes. Add wine; cook 2 minutes. Stir in Boursin cheese; cook until melted. Toss with beans; transfer to baking dish.

Steps:

• Make the casserole:
• Preheat oven to 425ºF. Line 2 rimmed baking sheets with parchment paper. Arrange mushrooms and 2 thyme sprigs in a single layer on prepared baking sheets. Drizzle with oil; season with 3/4 tsp. salt and 1/2 tsp. pepper. Roast mushrooms, stirring once and rotating pan halfway through, until lightly golden, crisp-tender, and liquid is evaporated (watch carefully as cook time can vary between types of mushrooms), 25-35 minutes. Remove sheets from oven and reduce oven temperature to 375ºF.
• Meanwhile, cook green beans in a large pot of boiling generously salted water until crisp-tender, 3-5 minutes. Drain in a colander and rinse under cold water to stop cooking. Drain well, then layer on a rimmed baking sheet with paper towels and pat dry. Wipe pot dry.
• Melt butter over medium-low heat in same pot. Add onion and garlic and cook, stirring occasionally, until tender, 5-8 minutes. Stir in flour and cook, stirring occasionally, until aroma is mildly nutty, 4-6 minutes. Add 3 Tbsp. cream and stir well to combine. Repeat twice, then stir in remaining cream, broth, bay leaves, and remaining 2 thyme sprigs. Bring to a simmer and cook, stirring occasionally and scraping sides of pot, until sauce is the consistency of slightly thickened cream and coats the back of a wooden spoon, about 20 minutes (do not over-reduce). Discard thyme and bay leaves. Stir in zest, 1/2 tsp. salt, and 1/4 tsp. pepper.
• Arrange beans and mushrooms in 3-qt. baking dish. Pour cream sauce over; stir to evenly coat. Bake casserole until sauce is thickened and bubbling around the edges, about 20 minutes.
• Make the fried onion topping:
• Pour oil into a large wide pot or high-sided skillet to a depth of 1/2". Heat over medium-high until hot but not smoking (about 350°F on a deep-fry thermometer). Line a rimmed baking sheet with paper towels.
• Whisk cornmeal, cornstarch, paprika, coriander, and cumin in a large shallow bowl. Toss onion rings in cornstarch mixture to coat.
• Working in batches, fry onion rings, stirring and turning occasionally, until golden and crisp, 2-3 minutes. Using tongs or a slotted spoon, transfer to prepared sheet to drain. Season with salt and pepper while hot.
• Bake the casserole:
• Arrange beans and mushrooms in a 3-quart baking dish. Pour cream sauce over; stir to evenly coat. Bake at 375ºF until sauce is thickened and bubbling around edges, about 20 minutes.
• Top casserole with fried onions and serve warm.
• Do Ahead
• Onions can be fried 1 day ahead. Let cool. Arrange in a flat layer on a paper towel-lined rimmed baking sheet, cover loosely with foil, and store at room temperature.
• Green beans and mushrooms can be cooked 3 days ahead; keep chilled in separate airtight containers. Let come to room temperature before using.
