Ingredients

Makes 4 servings · serves 4

Main

  • 1 lb ground beef
  • 16 oz frozen cut green beans
  • 1 packet onion soup mix
  • 1 can condensed mushroom soup

Topping

  • 1 cup french fried onions
Contains: gluten, milk

Why this recipe works

The slow cooking method allows the ground beef to release its juices, which then mingle with the condensed mushroom soup and the onion soup mix to create a rich, savory gravy.

By layering the ingredients, the beans are gently steamed by the rising moisture, ensuring they remain tender without becoming mushy. This process creates a balanced texture where each component retains its integrity while contributing to the overall depth of the dish.

Additionally, the slow cooker provides a controlled environment that ensures even heat distribution throughout the cooking duration. This consistency is crucial for breaking down the proteins in the ground beef while infusing the green beans with the savory notes of the onion and mushroom.

By the time the cooking cycle is complete, the flavors are perfectly melded, resulting in a dish that feels like it has been simmering on the stove for hours with almost no active oversight.

Notes and substitutions

When selecting ingredients, choose a lean ground beef to minimize excess grease in the final dish. If using a higher fat content, it is advisable to drain any rendered fat before serving. The frozen cut green beans are ideal here as they are pre-washed and chopped, saving significant preparation time. Ensure that the condensed mushroom soup is fully incorporated during the final stir for the best consistency.

The choice of equipment is straightforward; any standard oval or round slow cooker will work perfectly for this recipe. If your slow cooker has a particularly high heat setting, you may want to check the internal temperature of the beef earlier than suggested to prevent overcooking.

Feel free to adjust the amount of onion soup mix if you prefer a more pronounced onion flavor, though the standard packet is generally sufficient for a balanced result.
