Equipment

  • 9" x 9" baking dish
  • Large skillet

Ingredients

  • 2 tablespoon vegan butter
  • 1 cup mushrooms, finely chopped
  • 2 tablespoon all purpose flour
  • ¾ cup vegetable broth
  • 1 cup unsweetened almond milk
  • 1 teaspoon soy sauce
  • ¼ teaspoon garlic powder
  • ½ teaspoon onion powder
  • ¼ teaspoon pepper
  • ½ teaspoon salt (or less depending on salt preference)
  • 2 cans French style green beans, drained
  • 1 ½ cups crispy fried onions, divided

Instructions

  • Preheat the oven to 400°.
  • Prepare the mushrooms by finely chopping them.
  • In a large skillet, melt the vegan butter over medium heat. Add the mushrooms and saute for 4-5 minutes.
  • Add the flour and whisk to combine. Keep whisking as it cooks for 1 minute.
  • Add the vegetable broth and whisk until very well combined.
  • Add the unsweetened almond milk, soy sauce, salt, pepper, garlic and onion powder. Cook for 5 minutes while whisking occasionally. Sauce will thicken.
  • Pour the drained green beans in a 9" x 9" baking dish.
  • Add ½ cup of the crispy fried onions to the green beans.
  • Pour in the creamy mushroom sauce into the baking dish and stir until combined.
  • Sprinkle the remaining 1 cup of crispy fried onions over the top of the creamy green bean mixture.
  • Bake in the preheated oven for 15 minutes. Let sit about 10 minutes before serving.
  • Store leftovers in an airtight container in the fridge for up to 4 days.

Notes

  • Even if you prefer fresh green beans, in this recipe canned French style green beans are best. Make sure they are well drained before putting them in the baking dish. If you must use fresh, check out the FAQs for tips.
  • I recommend Earth Balance vegan butter.
  • My favorite brand of crispy fried onions is French's. Don't double the amount of fried onions you put in, even if you love them. I made that mistake once and it came out really oily.
