  • 2 pounds green beans fresh
  • 1 cup mushrooms
  • ½ onion yellow
  • 1 tablespoon olive oil
  • ½ cup butter
  • 3 tablespoons flour all-purpose
  • 1 ½ cups milk whole
  • 2 cups stock chicken or vegetable
  • 1 cup pepper jack cheese
  • 1 package French fried onions
  • salt and pepper to taste


  • Remove the ends of the green beans and chop into 1-inch pieces. 
  • Bring a pot of salted water to a boil and cook the green beans until just tender. Remove from water and allow to cool (keep in mind they will continue to cook a little more). If they are already as soft as you prefer, you can add them to an ice water bath to stop the cooking process. 
  • In a small pot, saute the chopped mushrooms and onions in the olive oil over medium heat until the onions have softened. Set aside.
  • In a pot, melt the butter. Add the flour and whisk to combine. Allow this to cook/bubble for 2 minutes. 
  • Now, add the milk and broth. Stir to combine. Add in the cheese. Season with a little salt and pepper if needed. 
  • Now add in the green beans, onion/mushroom mixture and stir so every bean is coated. Then stir in half the French fried onions.
  • Pour this mixture into ramekins or your square baking dish.
  • Bake at 350°F for 28-30 minutes. Top with the remaining French fried onions during the last 5-8 minutes of cooking.
