  • 1 lb . Fresh Green Beans, or haricot verts
  • 2 c . Chopped Mushrooms
  • 1 tbsp . Butter
  • 2 tbsp . All-Purpose Flour
  • 1 c . Low Sodium Chicken Chicken
  • 1 c . Fat Free 1/2 & 1/2
  • 2 c . French Fried Onions, divided, Durkee or homemade
  • Salt and Pepper, to taste


  • Preheat oven to 350 degrees F.
  • Trim the ends of the green beans; then cut them in half.
  • Next, blanch the beans in boiling water for about 2 minutes or cook over a double boiler. You want to them to turn bright green and still be a little crisp. Remove the beans, drain the water and set aside.
  • In the same pot (or bottom of the double boiler), melt the butter and add diced mushrooms. Cook until they start to soften; then whisk in flour to form a roux. Add chicken stock and 1/2 & 1/2 and mix until it thickens.
  • Add the beans back into the pot along with 1 c. fried onions; mix well.
  • Place in an oven safe baking dish and bake for 20 minutes; then place the remaining fried onions on top and bake for an additional 5 minutes until golden brown and bubbly.
