Ingredients

  • 8 cups string beans blanched
  • 3 Tbsp extra virgin olive oil divided use
  • 1 cup white button mushrooms quartered
  • 2 cloves garlic peeled and minced
  • 2 Tbsp whole wheat flour
  • 1/2 cup low-sodium chicken broth
  • 1 cup organic whole milk
  • 4 Tbsp parmesan cheese grated, divided use
  • 1 cup white onion thinly sliced
  • 3/4 cup whole wheat panko breadcrumbs
  • 1/4 cup fresh parsley chopped

Instructions

  1. Preheat oven to 375 F and spray a large casserole dish with nonstick cooking spray. Set aside.

  2. Heat 1 Tbsp oil in a large nonstick skillet over medium-high heat, add mushrooms and garlic, cook for 5-8 minutes, or until mushrooms are tender, stirring occasionally.

  3. Meanwhile, combine the flour and broth in a separate bowl and whisk together.

  4. Once mushrooms are tender, reduce the heat to medium, and add broth mixture to skillet. Whisk the mushroom broth and cook for about 2 minutes.

  5. Slowly add milk to the skillet, stirring continuously.

  6. Reduce the heat to medium-low and cook the mushroom sauce for approximately 3-5 minutes, or until the sauce begins thicken. Stir in 2 Tbsp parmesan, mix well and remove from heat.

  7. Mix the blanched green beans and mushroom sauce together, ensuring that the beans are equally covered in mushroom sauce. Transfer to casserole dish and set aside.

  8. Spray the same skillet you used for the mushroom sauce with nonstick cooking spray and place over medium-high heat. Add the thinly sliced onions, and cook for 8-10 minutes, until the onions are soft and begin to brown, stirring frequently. Remove from heat. 

  9. In a separate bowl, combine onions, panko crumbs, remaining 2 Tbsp. parmesan, parsley and remaining 2 Tbsp. oil. Stir well and sprinkle onion mixture over the green beans and place casserole in oven. Cook for 25-30 minutes.

  10. Serve immediately.  Leftover can be stored in an airtight container for up to 5 days.
