Ingredients Equipment Method Notes

Ingredients
  

  • 1/2 cup milk whole or 2%
  • 1 teaspoon soy sauce
  • 1/4 teaspoon black pepper
  • 4 ounces sliced mushrooms, sauteed optional

Equipment

  • 9x13 inch baking dish
  • Large bowl
  • Measuring cups
  • Measuring spoons
  • Can opener (if using canned green beans or soup)
  • Colander (if using canned green beans)
  • Pot (if using fresh green beans)

Method
 

  1. Preheat oven to 350°F (175°C).
  2. If using canned green beans, drain them well. If using fresh, blanch them and then drain well.
  3. In a large bowl, combine the drained green beans, cream of mushroom soup, milk, soy sauce, black pepper, and half of the French fried onions. If using sauteed mushrooms, add them here as well. Mix everything together until well combined.
  4. Pour the mixture into a 9x13 inch baking dish.
  5. Bake for 20-25 minutes, or until the casserole is bubbly and heated through.
  6. Remove the casserole from the oven and sprinkle the remaining French fried onions evenly over the top.
  7. Return the casserole to the oven and bake for another 5-10 minutes, or until the onions are golden brown and crispy. Watch them carefully so they don't burn!
  8. Let the casserole rest for a few minutes before serving.

Notes

To prevent a soggy casserole, ensure green beans are well-drained. Add a tablespoon of flour to the soup mixture to help thicken it. For crispy fried onions, add them at the very end and spread in a single layer. The casserole can be assembled up to 24 hours in advance and stored in the refrigerator. Add shredded cheddar cheese for a cheesy twist, or red pepper flakes for a spicy kick. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days and reheated in the oven or microwave.
