Difficulty Level
Easy – accessible for cooks of any experience
Ingredients
- 1 lb fresh green beans, trimmed and cut into 2-inch pieces
- 1 cup raw cashews, soaked in hot water for 20 minutes
- 8 oz mushrooms, finely chopped (cremini or button)
- 1 medium yellow onion, thinly sliced
- 2 cloves garlic, minced
- 2 tablespoons olive oil or vegan butter
- 2 cups vegetable broth, preferably low sodium
- 1 tablespoon all-purpose flour or gluten-free alternative
- 1 teaspoon soy sauce or tamari for depth of flavor
- 1/2 teaspoon smoked paprika
- Salt and freshly ground black pepper to taste
- 1/2 cup walnuts, roughly chopped and toasted
- 1 cup crispy fried onions, store-bought or homemade (see tips)
- Fresh parsley, chopped, for garnish
Instructions
- Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch casserole dish.
- Prepare the green beans: Blanch the trimmed green beans in boiling salted water for 3 minutes until bright green and slightly tender. Drain and immediately plunge into ice water to stop cooking; drain again and set aside.
- Create the creamy sauce: Drain the soaked cashews. In a blender, combine cashews, vegetable broth, soy sauce, smoked paprika, and a pinch of salt and pepper. Blend until smooth and creamy; set aside.
- Sauté the mushroom mixture: Heat olive oil in a skillet over medium heat. Add the sliced onions and cook until translucent. Add minced garlic and chopped mushrooms, cooking until mushrooms release their moisture and turn golden brown, about 8 minutes. Stir occasionally to prevent sticking.
- Incorporate the flour: Sprinkle the flour over the sauteed mushrooms and onions. Stir for 1-2 minutes to cook out the raw flavor, ensuring the mixture thickens slightly.
- Add the blended sauce to the skillet. Stir continuously and simmer for 5 minutes until the sauce thickens and coats the mushroom mixture beautifully. Adjust seasoning with salt and pepper as needed.
- Combine and assemble: Toss the blanched green beans in the creamy mushroom sauce until well coated. Transfer the mixture evenly to the prepared casserole dish.
- Add crunchy toppings: Evenly sprinkle toasted walnuts and crispy fried onions over the top for a delightful textural contrast.
- Bake uncovered for 25-30 minutes or until the top is golden and bubbly.
- Garnish with fresh parsley before serving to add a vibrant pop of color and freshness.
Tips for Success
- Make ahead: Prepare the creamy sauce and mushroom mixture a day in advance. Store in airtight containers and assemble just before baking.
- Cashew alternative: For nut-free options, substitute soaked sunflower seeds or use commercial vegan cream available in stores.
- Crispy fried onions: For a homemade version, thinly slice onions, coat lightly in flour and salt, and fry in oil until golden crisp. Drain on paper towels to remove excess oil.
- Adjust sauce thickness: If the sauce seems too thick before baking, whisk in a little more vegetable broth. If too thin, cook a few minutes longer on the stove to reduce.
- Flavor boost: Add a splash of white wine or a teaspoon of Dijon mustard to the sauce mixture for complexity.
Serving Suggestions for a Memorable Vegan Feast
Pair this simple vegan green bean casserole delight with roasted garlic mashed potatoes or creamy polenta to create a cozy holiday or weekend meal. A side of oven-roasted baby carrots glazed with maple syrup complements the creamy casserole’s earthiness beautifully. For added color and freshness, a crisp kale salad with lemon vinaigrette offers a refreshing counterbalance.
Garnish each serving with freshly chopped herbs like thyme or chives to enhance the aroma. Serve straight from the casserole dish to maintain warmth and encourage sharing. Add rustic sourdough bread or vegan dinner rolls for soaking up every last morsel of the rich sauce.

Q&A
Q&A: A Flavorful Twist – Simple Vegan Green Bean Casserole Delight
Q1: What makes this vegan green bean casserole different from the traditional version?
A1: This vegan green bean casserole offers a delicious twist by swapping out cream-based soups and crispy fried onions with plant-powered ingredients. Instead of heavy cream, it uses a creamy cashew or coconut-based sauce, and for that irresistible crunch, it features baked or toasted onions made from scratch. The result is a lighter, yet equally comforting dish bursting with flavor.
Q2: How do you achieve that creamy texture without dairy?
A2: The secret lies in blending soaked cashews, coconut milk, or silken tofu with sautéed mushrooms, garlic, and a splash of vegetable broth. This creates a velvety, savory sauce that mimics the richness of traditional cream soups without any dairy. Herbs and nutritional yeast add an umami depth that takes this casserole to the next level.
Q3: Can this recipe be prepared ahead of time?
A3: Absolutely! The casserole can be assembled and refrigerated a day before baking. Just be sure to add the crispy onion topping right before popping it in the oven to maintain that perfect crunch. This makes it a fantastic option for holiday meals or busy weeknights when you want a comforting dish with minimal stress.
Q4: What are some tips for selecting the best green beans?
A4: For the freshest flavor and texture, go for firm, bright green beans without blemishes or wrinkles. If using frozen green beans, make sure to thaw and drain them properly to avoid excess moisture in your casserole. You can also blanch fresh green beans briefly before adding them to keep their vibrant color and slight crunch.
Q5: Is this casserole suitable for gluten-free diets?
A5: Yes! Simply swap the traditional fried onion topping, which often contains wheat flour, for gluten-free crispy onions or homemade baked shallots. Additionally, ensure your vegetable broth and other ingredients are labeled gluten-free. This way, everyone at the table can enjoy this delicious and inclusive side dish.
Q6: How can I add an extra flavor boost or creative flair?
A6: Experiment by incorporating toasted almonds or walnuts for a nutty crunch, or add a splash of tamari or soy sauce to the sauce for a savory umami kick. Fresh herbs like thyme or rosemary bring aromatic warmth, while a hint of smoked paprika or cayenne pepper can give the casserole a subtle spicy edge. The possibilities are endless in this flavorful vegan delight!
