Classic Vegetarian Green Bean Casserole With Creamy Mushroom Sauce

Classic Vegetarian Green Bean Casserole With Creamy Mushroom Sauce is a delicious, wholesome dish that captures the comforting flavors of traditional green bean casserole, but without any meat products. This festive and hearty side dish features tender green beans, a rich and creamy mushroom sauce, and crispy fried onions, making it a perfect addition to any holiday dinner or family gathering.

Cooking Steps

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C).
2. Prepare the Green Beans: Rinse the fresh green beans and trim the ends. If desired, cut them into smaller pieces (about 1-2 inches).
3. Blanch the Green Beans: Boil a pot of water and add the green beans. Blanch them for about 4-5 minutes until they turn bright green and are tender-crisp. Drain and immediately plunge them into a bowl of ice water to stop the cooking process. Once cooled, drain again and set aside.
4. Cook the Onion and Garlic: In a large skillet, heat the olive oil over medium heat. Add the chopped onion and sauté for about 3-4 minutes until it becomes translucent. Add the minced garlic and cook for an additional 1 minute, stirring frequently to prevent burning.
5. Add the Mushrooms: Stir in the sliced mushrooms and cook for about 5-7 minutes until they are softened and have released their moisture.
6. Make the Creamy Sauce: Sprinkle the flour over the mushroom mixture and stir well. Gradually whisk in the vegetable broth, ensuring there are no lumps. Add soy sauce, salt, and black pepper. Continue to stir until the mixture thickens, which should take about 3-4 minutes. Once thickened, stir in the cream (or vegan alternative) until fully incorporated.
7. Combine: In a large mixing bowl, combine the blanched green beans with the creamy mushroom sauce. Mix gently to coat the green beans evenly.
8. Assemble the Casserole: Transfer the green bean mixture into a greased 9×13-inch baking dish. Spread it out evenly.
9. Top with Crispy Onions: Evenly sprinkle the crispy fried onions over the top of the casserole.
10. Bake: Place the baking dish in the preheated oven and bake for about 25-30 minutes, or until the casserole is bubbly and the onion topping is golden brown.
11. Serve: Remove from the oven and let it cool for a few minutes before serving. Enjoy this comforting vegetarian green bean casserole with your loved ones!

This dish is not only comforting and flavorful but also makes a delicious side for holiday meals or any family gathering, adding a touch of elegance to your table.

Cooking Steps

1. Preheat the Oven: Preheat your oven to 350°F (175°C) to prepare for baking the casserole.

6. Make the Cheese Sauce: Sprinkle the flour over the mushroom and onion mixture, stirring well to combine. Slowly whisk in the vegetable broth to avoid lumps. Add soy sauce, salt, and black pepper, cooking the mixture for about 3-4 minutes until it thickens. Remove from heat and stir in the cream cheese and shredded cheese until fully melted and combined.
7. Combine Ingredients: In a large mixing bowl, combine the blanched green beans with the cheese sauce mixture, stirring to ensure that the beans are evenly coated.
8. Assemble the Casserole: Pour the green bean and cheese mixture into a greased casserole dish, spreading it out evenly. Top with crispy fried onions and additional cheese if desired.
