  • 16 oz frozen green beans
  • ¾ cup sliced mushrooms
  • 4 tbsp vegetable stock
  • 2 tbsp gluten-free flour
  • 1 ½ cups unsweetened soy milk
  • 1 tbsp dijon mustard
  • ½ tsp salt
  • ¼ tsp sage
  • ¼ tsp oregano
  • ¼ tsp black pepper
  • 1 small white onion finely sliced
  • ¼ cup gluten free Panko breadcrumbs


  • Preheat oven to 375 F. Add green beans, then mushrooms to casserole dish. Set aside.
  • In a saucepan on low heat, add 2 tbsps of vegetable stock. Stir in the gluten-free flour until a paste is formed. Add soy milk, dijon mustard, salt, pepper, sage, and oregano. Whisk together. Continue to whisk until sauce begins to thicken. Remove from heat, and set aside.
  • Add 2 tbsp of vegetable stock to fry pan. Add thinly sliced onions. Sauté until soft about 3 minutes. Sprinkle gluten-free breadcrumbs overtop. Continue to sauté for an additional 2-3 minutes or until breadcrumbs are toasted and onions begin to brown.
  • Pour cream sauce overtop the mushrooms and green beans. Top with onions and breadcrumbs. Add a touch more breadcrumbs if you desire.
  • Bake for 35 minutes. Remove and allow to cool for 10 minutes before serving.

  • Will freeze for 2-3 months.
  • There is no need to defrost the green beans prior to cooking.

  • Be sure to use unsweetened plain soy milk, no vanilla or sugar added. If you can't find unsweetened soy milk, use unsweetened coconut milk, or cashew milk.
