Vegan Green Bean Casserole

Green bean casserole is a true fall comfort dish; its creamy sauce, tender green beans and crunchy onion topping will have everyone coming back for seconds. We substituted a few vegan ingredients, such as unsweetened almond milk and vegan sour cream, for an equally comforting side dish that all can enjoy. Assemble the entire casserole in a large oven-proof skillet for easy cooking and minimal cleanup.

Ingredients

Kosher salt

1 1/4 pounds green beans, trimmed and cut into 2-inch pieces

3 tablespoons olive oil

8 ounces cremini mushrooms, thinly sliced

Freshly ground black pepper

1 medium onion, finely diced

2 cloves garlic, minced

1 tablespoon fresh thyme leaves

3/4 cup low-sodium vegetable broth

3 tablespoons all-purpose flour

1 cup unsweetened, unflavored almond milk

1/3 cup dairy-free sour cream

1 teaspoon soy sauce

2 cups crispy fried onions

Directions

  1. Preheat the oven to 400 degrees F.
  2. Bring a large pot of salted water to a boil and fill a large bowl with ice water. 
  3. Add the green beans to the boiling water and cook until crisp-tender and bright green, 4 to 5 minutes. Drain well and transfer to the ice water to cool completely. Drain again and transfer to a paper towel-lined baking sheet; pat dry. 
  4. Meanwhile, heat the olive oil in a large oven-proof skillet over medium-high heat. Add the mushrooms, a pinch of salt and several grinds of pepper and cook, stirring occasionally, until almost all the excess moisture has cooked off and the mushrooms start to turn golden brown, about 6 minutes. Add the onion, garlic and thyme, then continue to cook, stirring, until tender, about 2 minutes.  
  5. Pour 1/4 cup of the vegetable broth into the skillet. Cook, using a wooden spoon to scrape up any browned bits from the bottom of the pan. Simmer until broth is reduced by half, about 1 minute. Stir in the flour and cook, stirring, until completely absorbed, then add the remaining 1/2 cup vegetable broth, almond milk, 1/2 teaspoon salt and several grinds of pepper. Cook, stirring, until thickened and saucy, 3 to 4 minutes. Stir in the vegan sour cream and soy sauce until smooth. Taste and adjust the seasoning with salt and pepper.  
  6. Stir the blanched green beans into the sauce, tossing until evenly coated, then spread into an even layer. Top evenly with the fried onions.  
  7. Bake until golden brown and bubbling at the edges, about 15 minutes. Let sit 5 minutes before serving.
