Ingredients Method Notes

Ingredients
  

  • 2 15-ounce cans green beans, drained
  • 1 10.5-ounce can condensed cream of mushroom soup
  • 1/2 cup milk
  • 1 tsp soy sauce
  • 1/2 tsp black pepper
  • 1 1/3 cups French fried onions divided
Ingredient Substitutions
  • Use heavy cream for extra richness or unsweetened almond milk for lighter version
  • Replace canned beans with 2 lbs fresh beans blanched
  • Use homemade crispy shallots instead of French fried onions

Method
 

  1. Preheat oven to 350°F and grease a 9x9 baking dish.
  2. In a large bowl, combine green beans, mushroom soup, milk, soy sauce, pepper, and 2/3 cup onions. Mix well.
  3. Spread mixture evenly in prepared dish and bake 25 minutes until hot and bubbling.
  4. Top with remaining onions and bake an additional 5 minutes until golden and crispy.
  5. Rest 3-5 minutes before serving.

Notes

For best results, add onions in two stages—during mixing and again at the end—for maximum crunch. Assemble casserole up to 2 days ahead and bake fresh before serving.
