Ingredients

Scale

Vegetables

  • 1 lb fresh green beans, trimmed

Dressing

  • 1 can (10.5 oz) cream of mushroom soup
  • 1/2 cup whole milk (or dairy-free alternative)
  • Salt and pepper to taste

Topping

  • 1 cup fried onions (store-bought or homemade)

Instructions

  1. Prepare the Green Beans: Rinse the green beans under cold water and trim the ends off to ensure freshness and clean preparation.
  2. Blanch the Green Beans: Boil salted water and blanch the green beans for 3-4 minutes until crisp-tender. Then immediately drain and plunge them into ice water to stop the cooking and preserve their bright green color.
  3. Mix the Sauce: In a large bowl, combine the cream of mushroom soup with whole milk, seasoning it with salt and pepper to your taste to create a creamy mixture.
  4. Combine Beans and Sauce: Gently fold the blanched green beans into the mushroom soup mixture, ensuring each bean is well coated with the sauce.
  5. Assemble the Casserole: Transfer the green bean and mushroom mixture into a greased baking dish. Evenly spread the fried onions over the top to form a crispy crust.
  6. Bake the Dish: Bake at 350°F (175°C) for 25-30 minutes until the casserole is bubbly and the onions on top are golden brown and crisp.

Notes

  • For a dairy-free version, substitute milk with almond or oat milk and use a dairy-free cream of mushroom soup.
  • You can make your own fried onions by thinly slicing onions, coating them lightly with flour, and frying until golden and crispy.
  • Blanching the green beans helps retain their bright color and crisp texture while preventing overcooking during baking.
  • This casserole can be prepared ahead of time and baked just before serving.
  • Adjust seasoning according to your preference; a dash of garlic powder or thyme can complement the mushroom flavor.
