Ingredients
  

  • 4 cups fresh green beans, trimmed and cut into pieces
  • 2 cans (10.5 ounces each) condensed cream of mushroom soup
  • ½ cup milk
  • 1 cup sliced fresh mushrooms
  • 1 teaspoon soy sauce
  • ½ teaspoon garlic powder
  • ½ teaspoon black pepper
  • ¼ teaspoon salt, or to taste
  • 1 cup crispy fried onions, divided
  • ½ cup shredded cheddar cheese (optional)
  • 1 tablespoon butter

Instructions
 

  • Wash the fresh green beans thoroughly. Remove the ends and cut them into bite-sized pieces. If using fresh green beans, blanch them in boiling water for approximately 3–4 minutes, then drain.
  • Take a large mixing bowl and add the condensed cream of mushroom soup and milk. Whisk until smooth and creamy.
  • Add soy sauce, garlic powder, black pepper, and salt to the mushroom mixture. Stir well to combine all the flavors.
  • Add the prepared green beans and sliced mushrooms to the creamy sauce. Mix gently until the vegetables are evenly coated.
  • Lightly grease the inside of a 5–6-quart slow cooker with butter or nonstick cooking spray. Transfer the green bean mixture into the slow cooker and spread it evenly.
  • Cover with the lid and cook on LOW for approximately 3–4 hours or until the green beans are tender. Cooking time may vary depending on your slow cooker and the type of green beans used.
  • If using cheddar cheese, sprinkle it over the casserole during the final 15 minutes of cooking. Add half of the crispy fried onions and gently mix.
  • Sprinkle the remaining crispy fried onions over the top just before serving. Garnish with fresh parsley if desired.

Notes

  • Fresh or Frozen Beans: Both fresh and frozen green beans work well in this recipe.
  • Canned Green Beans: Drain them thoroughly before adding to the mixture. Reduce cooking time to prevent them from becoming too soft.
  • Mushroom Soup: Condensed cream of mushroom soup creates the traditional creamy texture.
  • Seasoning: Adjust salt and pepper according to your preference.
  • Slow Cooker Size: A 5–6-quart slow cooker is ideal for this recipe.
  • Crispy Topping: Add fried onions near the end to maintain their crunch.
  • Cheese Option: Cheddar cheese adds extra richness and flavor.
  • Storage: Refrigerate leftovers in an airtight container within two hours.
