Equipment

  • 1 air fryer with baking dish
  • 1 mixing bowl large
  • 1 knife for chopping

Ingredients
  

Main Ingredients

  • 1 lb fresh green beans trimmed and halved
  • 1 can 10.5 oz cream of mushroom soup
  • 1/2 cup milk
  • 1 cup crispy fried onions

Optional Add-ins

  • 1/2 cup bacon bits
  • 1/2 cup shredded cheddar cheese

Instructions
 

Preparation

  • Trim the ends of the green beans and cut them into bite-sized pieces. If using fresh, blanch them in boiling water for 2-3 minutes and then cool them immediately in an ice bath.
  • In a large bowl, combine the blanched green beans, cream of mushroom soup, milk, and any optional add-ins. Stir until the green beans are evenly coated.

Cooking

  • Preheat your air fryer to 350°F. This ensures even cooking and a crispy top.
  • Transfer the green bean mixture to an air fryer-safe baking dish. Spread it evenly for consistent cooking.
  • Place the dish in the air fryer and cook for 15 minutes. Check halfway through and stir if necessary for even cooking.
  • After 15 minutes, evenly sprinkle crispy fried onions over the top of the casserole and cook for another 5 minutes until golden brown.

Serving

  • Let the casserole cool slightly before serving. Enjoy as a side dish with your favorite main course.

Storage

  • Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the air fryer or microwave before serving.
