Best Green Bean Casserole With Homemade Mushroom Gravy Recipes

CREAMY GREEN BEAN CASSEROLE FROM SCRATCH

Steps:

• Preheat the oven to 475°F (246°C). Line a large baking sheet with parchment paper or a silicone baking mat. Set aside.
• (while the onions bake, you can blanch the green beans- step 4.) Thinly slice the onion. Pour flour in one small bowl, Panko + salt + pepper into a medium bowl, and whisk the egg and milk together in another small bowl. To bread the onion slices, you'll want to use one hand for dry and one hand for wet. It helps things move a little quicker and easier. First, dip a few slices into the flour. Then into the egg mixture. And finally, give them a nice dunk into the Panko and coat them well. Place onto baking sheet. Repeat with the rest of the onions. Bake onions until golden brown, about 25 minutes. Flip them twice during this time. Set them aside.
• Reduce oven to 400°F (204°C).
• Bring a gallon of water and 1 Tablespoon of salt to a boil in a large saucepan. Add the beans and blanch for 5 minutes. Drain and immediately place into a large bowl filled with ice water to stop the cooking process. Drain again and set aside.
• Over medium-high heat, melt the butter in a large 10 - 12 inch ovenproof skillet. Add the mushrooms, 1 teaspoon salt, and the pepper. Cook, stirring occasionally, until the mushrooms begin to give off some of their moisture- about 5 minutes. Add the garlic, stir, and cook for another 2 minutes. Sprinkle the flour on top and stir until combined. The flour will soak up all the moisture. Add the chicken broth and simmer for 3 minutes. Decrease the heat to medium-low and add the half-and-half. Stirring occasionally, cook until the mixture is thick- about 10 minutes or maybe more if you prefer a thicker sauce.
• Remove from the heat and add 1/4 of the onions and all of the green beans. Give it a nice stir, combining the sauce and beans. Top with remaining onions and bake until bubbly, about 10-15 minutes. Remove from the oven and enjoy! Leftovers keep well in an airtight container in the refrigerator for up to 4 days. Reheat as desired.

GREEN BEAN MUSHROOM CASSEROLE

Steps:

• Make the casserole: 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 mushrooms; sauté until softened and most of the liquid has evaporated, 10 minutes. Sprinkle in the flour; cook, stirring, 1 minute. Add the broth and half-and-half. Bring to a boil, then reduce the heat to medium low and simmer until thickened, about 5 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 o any excess water and add to the mushroom sauce. Cook, stirring occasionally, until the beans are very tender, 10 to 12 minutes. Season with salt and pepper.
• Make the topping: Soak the sliced onion 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 o 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 onion. (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.)

HOMEMADE GREEN BEAN CASSEROLE

Steps:

• Make the onions: In a medium bowl, combine the onions with the flour, bread crumbs and salt, and toss to coat the onion pieces.
• In a heavy skillet with high sides, pour enough oil to reach 1/2-inch up the side. Heat over medium-high until the oil is hot - a drop of water should sizzle and sputter when flicked into the oil.
• Add the onions in batches, taking care not to overcrowd them. Fry until golden-brown (they don't have to be deep brown, as they'll continue cooking in the oven), about 5 to 6 minutes, then use a slotted spoon or a pair of tongs to transfer to paper towels. Sprinkle lightly with salt. Repeat until you've fried all of the onions.
• Butter a shallow 4-quart baking dish and heat the oven to 400 degrees.
• Blanch the green beans: Bring a large pot of water to a boil with an ice bath nearby. When boiling, salt the water generously, add the green beans, and cook for 4 to 5 minutes, until slightly tender and bright green. Immediately transfer beans to the ice bath. When beans are chilled, drain and set aside.
• Pour water out of the pot, wipe dry and return to the stovetop. Over medium-high heat, melt 3 tablespoons butter. When melted, add the red-pepper flakes and thyme, and stir until fragrant, about 1 minute. Add the sliced mushrooms and cook, stirring occasionally, until they start to brown significantly, 8 to 10 minutes. Add 1 teaspoon salt and sliced garlic and stir until fragrant, another 1 to 2 minutes.
• Sprinkle the flour all over and stir to coat the mushrooms. Gradually add the stock and milk, and bring to a simmer, stirring all the while. Turn the heat down to medium and continue to stir until the sauce is thick and creamy and coats the back of a spoon, 6 to 8 minutes. Remove from heat. Add nutmeg, black pepper, vinegar and Worcestershire, if using. Taste for salt, pepper and acidity.
• Add the green beans and half of the onions, stir to combine, and transfer to prepared baking dish. Top with remaining onions and bake for 15 to 20 minutes, until bubbling. Serve immediately.
