The Secret is in the Crispy Onions

The creamy sauce and 'cheesy' flavor are reasons enough to fall in love with this Green Bean Casserole but what elevates it the most are the salty and crispy onions on top. These little crunchers are absolutely delicious and can become the topping of many different dishes if you’re feeling creative. You can find them at Trader Joe’s, Sprouts, and other grocery stores. Beware, they are addictive.

How to Make Green Bean Casserole

Keep scrolling to the recipe card for the complete list of ingredients and recipe 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 ice­cold 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).
  • Melt the vegan butter in a large pot over medium­high heat. 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.

FAQs
