Instructions
 

Preparation

  • Preheat your oven to 350 degrees Fahrenheit.
  • Melt butter in a large skillet over medium heat.
  • Add onions and mushrooms, cooking and stirring occasionally until they are just tender.
  • Add garlic and cook for another 1-2 minutes, then remove from heat and set aside.
  • Place green beans and chicken broth in a medium saucepan, bringing it to a boil.
  • Cook the green beans for about 8 minutes until they are crisp-tender, then drain them.
  • Spray a 2-quart baking dish with cooking spray.
  • In a large bowl, combine the soup, mushroom mixture, green beans, Parmesan cheese, salt, and pepper. Stir to mix well.
  • Transfer the mixture to the prepared baking dish and top it with crispy onion strings.

Baking

  • Bake in the preheated oven for 20 minutes until the casserole is heated through.

Notes

Serve hot from the oven alongside your main course. Pairs well with roasted meats. Allow leftovers to cool completely and store in an airtight container in the refrigerator for 3-4 days.
