Ingredients

Scale

Main Ingredients:

  • 2 14.5 ounces (411 grams) green beans (any style, drained)
  • 1 10.5 ounces (298 grams) condensed cream of mushroom soup

Liquid and Seasoning:

  • 3/4 cup (180 milliliters) milk
  • 1/8 teaspoon pure ground black pepper

Topping:

  • 1 1/3 cups (106 grams) crispy fried onions (divided)

Instructions

  1. Prepare the oven at 350F and select a 1 1/2-quart baking dish for assembling the casserole.
  2. Whisk cream of mushroom soup with milk and ground black pepper until smoothly integrated.
  3. Fold drained green beans into the creamy mixture, ensuring even distribution of sauce throughout the vegetables.
  4. Incorporate 2/3 cup of crispy fried onions into the casserole, stirring gently to combine all ingredients.
  5. Transfer the casserole to the preheated oven and bake for 30 minutes, ensuring the mixture becomes thoroughly heated.
  6. Gently stir the casserole to redistribute the ingredients and promote even cooking.
  7. Sprinkle the remaining 2/3 cup of crispy fried onions across the top of the casserole.
  8. Return to the oven and bake an additional 5 minutes until the onion topping turns golden brown and crispy.
  9. For advance preparation, assemble the casserole and wrap tightly with plastic wrap and foil before freezing.
  10. When ready to serve from frozen, thaw overnight in the refrigerator and follow original baking instructions, extending cooking time as needed to reach 160F internal temperature.

Notes

  • Choose fresh green beans for a vibrant, crisp texture that elevates the entire dish’s quality.
  • Blanch green beans briefly in salted boiling water to maintain their bright color and prevent mushiness during baking.
  • Experiment with homemade crispy onions by thinly slicing sweet onions, coating in seasoned flour, and deep-frying for an extra crunchy topping.
  • Consider dairy-free alternatives like coconut milk or cashew cream for a lactose-intolerant friendly version that doesn’t compromise on rich, creamy flavor.
