Ingredients
  

For the casserole
  • 2 tablespoons butter for sautéing
  • 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 for cooking green beans
  • 1 can low-sodium cream of mushroom soup 10.75 ounce
  • 1/4 cup grated Parmesan cheese for flavor and thickening
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • crispy onion strings for topping

Method
 

Preparation
  1. Preheat the oven to 350 degrees Fahrenheit.
  2. In a large skillet, melt butter over medium heat.
  3. Sauté diced onions and mushrooms until just tender, stirring occasionally.
  4. Add garlic and cook for another 1–2 minutes, then remove from heat and set aside.
  5. In a medium saucepan, combine green beans with chicken broth and bring to a boil.
  6. Continue cooking for about 8 minutes, until beans are crisp-tender. Drain the green beans thoroughly and set aside.
Assembly
  1. Prepare a 2-quart baking dish by spraying it with cooking spray.
  2. In a large bowl, combine the soup, mushroom mixture, green beans, Parmesan, salt, and pepper. Stir to combine.
  3. Transfer the mixture to the prepared baking dish and top with crispy onion strings.
Baking
  1. Bake at 350 degrees Fahrenheit for 20 minutes, or until the casserole is heated through.

Notes

Serve hot to maintain the crunch of crispy onion strings. Can pair with roasted turkey, baked ham, or grilled chicken. Store leftovers in an airtight container for up to 3 days, keeping the crispy onions separate until ready to reheat.
