Ingredients
- 2 pounds green beans fresh
- 3 cups vegetable broth or equivalent amount of vegetable bouillon and water), divided
- ½ cup cashews raw
- ¼ teaspoon salt
- ½ teaspoon ground black pepper
- ½ cup vegan butter
- 1 onion diced, small
- 2 cups button mushrooms sliced or dicced
- 4 garlic roughly chopped, medium cloves
- ½ cup all-purpose flour
- 2 cups fried onions we use store-bought, crispy
Instructions
- To prepare the green beans, wash them, trim the stem ends, cut them in half, place them in a steamer basket, and steam for 7 minutes. Remove the green beans from the steamer, rinse them with ice cold water to preserve the green color, and set aside.
- In a highpowered blender, combine 1 cup of the vegetable broth and the cashews and blend on high until smooth. Blend in the remaining 2 cups of vegetable broth, salt, and pepper and set aside.
- Preheat the oven to 375 degrees F (190 degrees C).
- In a large pot over medium high heat, melt the vegan butter. Add the onion, mushrooms, and garlic and sauté for 5 minutes, stirring occasionally. Add the flour and whisk to create a roux. Continue to whisk the thickened roux constantly for 3 minutes. Add the broth and cashew mixture and whisk continuously for 2 to 3 minutes, until thickened (thickening will happen fast and suddenly, so be sure to turn off the heat just as the mixture gets thick enough).
- Spoon the green beans and the creamy mixture into a 9 × 13 inch baking dish and mix until well combined. Top with an even layer of fried onions and bake for 20 minutes.

Notes
- Using pre-sliced mushrooms and diced onions reduces prep time.
- Brown mushrooms enhance umami flavor better than white mushrooms.
- You can make your own crispy fried onions by sautéing thinly sliced onions in oil until browned and crisp.
- Steam green beans to your preferred doneness; less steam for tender-crisp, more for softer texture.
