Print Recipe

A dairy-free twist on the classic green bean casserole featuring tender-crisp green beans, a creamy mushroom sauce, and crispy golden onions for a comforting and crowd-pleasing side dish.

Ingredients

Scale
  • 1 pound fresh green beans, trimmed and blanched
  • 2 large onions, thinly sliced
  • 1 tablespoon dairy-free butter or olive oil (Earth Balance preferred)
  • 3 tablespoons dairy-free butter
  • 8 ounces finely chopped mushrooms (cremini or button)
  • 3 tablespoons all-purpose flour (or gluten-free flour as substitute)
  • 2 cups dairy-free milk (unsweetened almond or oat milk)
  • 1 cup vegetable broth
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • Salt and pepper to taste
  • Optional: nutritional yeast for cheesy flavor

Instructions

  1. Preheat oven to 375°F (190°C). Line a baking sheet with parchment paper.
  2. Thinly slice onions and toss with 1 tablespoon dairy-free butter or olive oil and a pinch of salt. Spread in a single layer on the baking sheet and roast for 25-30 minutes, stirring halfway, until golden and crispy. Watch closely to avoid burning.
  3. Trim and blanch green beans by boiling in salted water for 3-4 minutes until bright green and just tender. Immediately transfer to an ice bath to stop cooking. Drain and set aside.
  4. In a large skillet, melt 3 tablespoons dairy-free butter over medium heat. Add chopped mushrooms and sauté for 5-7 minutes until soft and browned.
  5. Sprinkle in 3 tablespoons flour and cook, stirring constantly, for 2 minutes to remove raw flour taste.
  6. Slowly whisk in 2 cups dairy-free milk and 1 cup vegetable broth. Add garlic powder, onion powder, salt, and pepper. Continue cooking and whisking until sauce thickens and becomes creamy, about 5-7 minutes. Remove from heat.
  7. Gently fold blanched green beans into the mushroom sauce until evenly coated.
  8. Transfer mixture to a baking dish (9×13-inch or similar). Spread evenly and top generously with roasted golden onions.
  9. Bake uncovered for 15-20 minutes until casserole bubbles lightly and onions are crisp and golden.
  10. Let rest for 5 minutes before serving.

Notes

Roast onions slowly for best crispness and caramelization. Add dairy-free milk gradually to avoid lumps in the sauce. Blanch green beans to keep them vibrant and crisp. Onions can be prepared ahead and stored up to 3 days refrigerated. For gluten-free, substitute flour with gluten-free blend or cornstarch. Nutritional yeast adds a cheesy flavor without dairy.
