  • 1 pound fresh green beans (rinsed and trimmed)
  • 8-12 ounces button mushrooms (trimmed and sliced)
  • 4-6 ounces french fried onions (homemade or store bought)
  • 2 TBSP butter or Earth Balance for vegan
  • 2 cloves garlic minced
  • 1/4 tsp nutmeg
  • 2 TBSP all-purpose flour
  • 1 cup mushroom broth or veggie broth
  • 1 cup almond milk
  • a sprinkle of garlic powder if you have it!
  • salt and pepper to taste


  1. Preheat oven to 400 F.
  2. Blanch green beans by bringing a pot or skillet of water to boil, adding green beans, then removing after 3-5 minutes. You'll want them bright green and slightly tender. While the green beans are cooking, add ice and water to a large bowl and set aside. This will serve as your "ice bath" to shock the green beans and prevent them from continuing to cook. No mushy green beans here! Once the beans have finished boiling, drain them in a colander, pop em in the ice bath, and then drain again.
  3. Set aside.
  4. Next melt your butter in a skillet on medium-high heat.
  5. Add the mushrooms, along with a sprinkle of garlic powder, salt, and pepper.
  6. Saute, stirring occasionally, until the mushrooms begin to give up some of their liquid.
  7. Next add the minced garlic and 1/4 tsp nutmeg and continue to cook for another 1 to 2 minutes.
  8. Add your flour and stir to combine.
  9. Cook for 1 minute and add the broth.
  10. Simmer for about a minute, then decrease the heat to medium-low.
  11. Add your almond milk and cook until the mixture thickens, stirring occasionally, for approximately 6 to 8 minutes.
  12. Remove from the heat and stir in 1/4 of the onions and all of the green beans.
  13. Top with the remaining onions.
  14. Place into the oven and bake until bubbly for approximately 15 minutes.
