Ingredients
  

Main
  • 1 1/2 pounds green beans trimmed and halved
  • 1 10 1/2 ounce can cream of mushroom soup
  • 2/3 cup whole milk
  • 1 1/3 cups fried onions divided
  • Pinch of salt
  • Pinch of pepper
  • 3 tablespoons shredded cheddar cheese optional

Method
 

  1. Boil a large pot of salted water. Add green beans and cook for 5 minutes until bright green and slightly tender. Drain and set aside. Alternatively, use frozen green beans.
  2. In a large bowl, combine cream of mushroom soup, milk, salt, and pepper. Stir in half of the fried onions.
  3. Add the green beans to the sauce mixture and toss to coat evenly. Transfer to a baking dish. Add shredded cheddar cheese if desired.
  4. Preheat the oven to 350°F (175°C). Bake uncovered for 25 minutes.
  5. Remove the casserole from the oven, top with remaining fried onions, and bake for another 5 minutes until onions are crispy.
  6. Let the casserole rest for 1–2 minutes before serving.

Notes

To make ahead, assemble the casserole through Step 3, cover, and refrigerate overnight. Bring to room temperature for 30 minutes before baking. Add the final layer of fried onions just before the last 5 minutes of baking to maintain their crispiness.
