Ingredients

Scale

Green Beans

  • 4 cups fresh green beans, stems removed and chopped into bite-sized pieces

Mushroom Sauce

  • 4 tablespoons butter
  • 1 large onion, minced
  • 2 cloves garlic, minced
  • ½ lb mushrooms (cremini, shiitake, baby bella), thinly sliced
  • ¼ cup white wine
  • 1 cup chicken broth
  • 1 teaspoon dried thyme
  • ½ teaspoon black pepper
  • ¼ cup heavy whipping cream
  • 2 tablespoons flour
  • 1 teaspoon salt

Topping

  • Onion straws (preferably homemade and crispy)

Instructions

  1. Prepare Onion Straws: Make your air fryer onion straws ahead of time to ensure they are crispy and ready for topping the casserole.
  2. Preheat Oven: Preheat your oven to 350°F (175°C) to get it ready for baking the casserole.
  3. Cook Green Beans: Trim and chop the fresh green beans, then boil them in water for 5-6 minutes until just tender. Drain and place them in your casserole dish. If using canned green beans, drain them first and skip this step.
  4. Sauté Aromatics: Melt 4 tablespoons of butter over medium heat in a skillet. Add the minced onion and cook until translucent, about 5 minutes. Add minced garlic and sauté for an additional 30 seconds to release its aroma.
  5. Add Mushrooms and Liquids: Add the sliced mushrooms, white wine, chicken broth, dried thyme, and black pepper to the skillet. Bring to a boil and let it cook for about 5 minutes to reduce and concentrate the flavors.
  6. Thicken Sauce: In a separate bowl, whisk together the heavy cream, flour, and salt until smooth. Stir this mixture into the skillet and let it simmer for about a minute until the sauce thickens. This step is crucial to prevent the casserole from becoming soupy.
  7. Combine Sauce and Beans: Pour the thickened mushroom sauce over the green beans in the casserole dish and gently stir to combine evenly.
  8. Bake Casserole: Bake the uncovered casserole in the preheated oven at 350°F for 30 minutes, allowing the flavors to meld and the sauce to set.
  9. Add Onion Straw Topping: Sprinkle the crispy onion straws evenly on top of the casserole. Return to the oven and bake for an additional 5 minutes until the onions turn golden and crispy.
  10. Serve: Remove from the oven and serve the casserole hot as a delicious side dish.

Notes

  • If using canned green beans, be sure to drain them well before adding to the casserole.
  • This casserole can be prepared a day in advance, but leave the onion topping off until just before baking.
  • For deeper flavor, combine different mushroom varieties such as cremini, shiitake, and baby bella.
  • Store leftover casserole in the refrigerator for 2-3 days. Reheat portions in the microwave; however, the onion straws will lose their crispiness but remain tasty.
