Before you start

Before beginning, ensure all vegetables are properly washed and prepared. Dice the gold potatoes into uniform half-inch cubes to ensure they cook evenly. Slice the mushrooms thinly to maximize their surface area, which helps them release their earthy flavor into the broth as the soup cooks.

Keep the turkey refrigerated until the moment it is needed to maintain food safety, and clear your counter space to allow for an organized assembly process.

Ingredients at a glance (6)
  • 1 lb ground turkey
  • 8 oz sliced mushrooms
  • 2 cups diced gold potatoes
  • 1 cup shredded Swiss cheese
  • 1 packet dry onion soup mix
  • 4 cups creamy beef broth

Instructions

Initial Assembly

  1. Assemble the base
    Place the raw ground turkey into the bottom of a slow cooker, ensuring the meat is broken into small crumbles. Add the sliced mushrooms and the diced gold potatoes on top of the turkey.
    Look for The turkey is spread evenly across the bottom of the slow cooker ceramic insert.
    Tip Ensure the turkey is broken into small pieces to allow for even cooking.

At this phase, the slow cooker insert should contain the raw turkey, mushrooms, and potatoes. The turkey should be spread out in a single layer at the bottom to ensure it cooks thoroughly. Check that your ingredients are fresh and that the potatoes are cut to a uniform size to avoid uneven cooking later in the process.

Seasoning and Liquid Addition

  1. Season and pour
    Sprinkle the dry onion soup mix over the vegetables and meat. Top with the shredded Swiss cheese, then pour the creamy beef broth over the entire mixture to submerge the ingredients.
    Look for The broth reaches the top of the ingredients and the cheese is distributed.
    Tip Pouring the broth slowly helps keep the seasonings in place.

The soup is now ready for the slow cooker. Ensure the onion soup mix is evenly distributed over the vegetables and that the shredded Swiss cheese is spread across the top.

Once the creamy beef broth is poured in, the ingredients should be submerged. Ensure the slow cooker lid is securely placed before you begin the cooking cycle.

Cooking and Finishing

  1. Slow cook and serve
    Cover and cook on low for 4 to 6 hours or on high for 3 hours, until the turkey reaches an internal temperature of 165°F (74°C) and the potatoes are fork-tender. Stir well before serving hot in shallow bowls.
    Look for The soup is thickened, the potatoes are soft, and the turkey is fully cooked through.
    Safe temperature 165°F (74°C) internal temperature (poultry)
    Tip Stir the soup vigorously at the end to ensure the cheese is fully melted and incorporated.

After the cooking time, the soup should look rich and smell savory. The turkey should be fully cooked, and the potatoes should be tender. Before serving, give the soup a thorough stir to ensure the melted cheese is fully incorporated into the broth, creating a smooth and uniform consistency throughout the entire dish.

Common mistakes

A common mistake is overcrowding the slow cooker or failing to break the turkey into small enough pieces, which can lead to large, uneven clumps. Another error is using potatoes that are cut too large, as they will remain hard in the center while the turkey overcooks.

Finally, avoid lifting the lid frequently during the cooking process, as each lift releases heat and significantly increases the total cooking time required for the meal.

How to tell it’s done

The soup is done when the ground turkey has reached an internal temperature of 165°F (74°C) as verified by a food thermometer. You should also check the potatoes; they are perfectly cooked when they can be easily pierced with a fork with no resistance.

The soup should have a thick, creamy consistency and the Swiss cheese should be completely melted and integrated into the broth.

  • Poultry: 165°F (74°C) in the thickest part
