Ingredients
  

For the casserole

  • 2 tablespoons butter
  • 2 cloves garlic (minced)
  • 1/2 cup onion (finely diced)
  • 8 ounce package button mushrooms (sliced)
  • 3 cups fresh green beans (ends removed and cut in half)
  • 3 cups low-sodium chicken broth
  • 1 can (10.75 ounce) low-sodium cream of mushroom soup
  • 1/4 cup grated Parmesan cheese
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • crispy onion strings For topping

Instructions
 

Preparation

  • Preheat the oven to 350 degrees.
  • In a large skillet, melt butter over medium heat.
  • Sauté diced onions and mushrooms until just tender, stirring occasionally.
  • Add garlic and cook for another 1–2 minutes, then remove from heat and set aside.
  • In a medium saucepan, combine green beans with chicken broth. Bring to a boil.
  • Continue cooking for about 8 minutes, until beans are crisp-tender. Drain the green beans thoroughly and set aside.
  • Prepare a 2-quart baking dish by spraying it with cooking spray.

Assembly and Cooking

  • In a large bowl, combine the soup, mushroom mixture, green beans, Parmesan, salt, and pepper. Stir to combine.
  • Transfer the mixture to the prepared baking dish and top with crispy onion strings.
  • Bake at 350 degrees for 20 minutes, or until the casserole is heated through.

Notes

Serve the casserole warm as a side dish, and consider using fresh herbs for added flavor. Drain green beans well to avoid a watery casserole. Can be made vegetarian by swapping chicken broth for vegetable broth.
