Before you start
Before beginning, ensure all ingredients are measured and ready. Pat the turkey tenderloins dry with paper towels to remove excess moisture, which helps the seasonings stick. Have your slow cooker clean and placed on a stable surface.
Ensure you have a reliable meat thermometer on hand, as it is the only accurate way to verify the turkey reaches the necessary temperature of 165°F (74°C) for food safety, ensuring the meal is safe and perfectly cooked.
Ingredients at a glance (7)
- 2 lb turkey tenderloins
- 4 slices deli ham
- 4 slices Swiss cheese
- 1 tsp mustard powder
- 1/2 tsp garlic powder
- 1 can (10.5 oz) cream of chicken soup

Instructions
Assembly of the layers
- Layering the ingredientsPlace the raw turkey tenderloins in an even layer at the bottom of the slow cooker insert. Top the turkey with slices of ham followed by slices of Swiss cheese. Sprinkle the mustard powder and garlic powder evenly over the cheese layer.Look for Ensure the turkey is in a single layer for even cooking.Tip Pat the turkey dry with paper towels before placing it in the slow cooker to help the seasoning adhere better.
The turkey should be arranged in a single, snug layer at the bottom of the slow cooker, with the ham and Swiss cheese distributed evenly on top.
The seasonings should be sprinkled uniformly over the cheese to ensure the flavor is balanced across the entire dish before the liquid components are added.
Adding the sauce
- Preparing and adding the sauceIn a small bowl, whisk together the cream of chicken soup and the chicken broth until smooth. Pour this mixture evenly over the turkey, ham, and cheese layers in the slow cooker. Cover the slow cooker with the lid.Look for The sauce should be completely combined before pouring.Tip Use a whisk to ensure no lumps remain in the soup mixture for a velvety final sauce.
The soup and broth mixture must be whisked until completely smooth and free of lumps. After pouring, the liquid should settle around the sides of the tenderloins. The slow cooker should be covered securely with the lid to begin the braising process, ensuring no heat escapes.
Final cook and rest
- Cooking to temperatureCook on low for 4 hours. Check that the turkey has reached an internal temperature of 165°F (74°C) using a meat thermometer inserted into the thickest part. Once cooked, let the turkey rest for 5 minutes before serving with the creamy sauce.Look for The sauce will be bubbly and the cheese melted into the cream base.Safe temperature 165°F (74°C) internal temperature (poultry)Tip Avoid lifting the lid during the cooking process to maintain a consistent temperature inside the slow cooker.
At the end of the cooking time, the turkey will be tender and the sauce will be thick and creamy. The internal temperature must reach 165°F (74°C). The meat should rest for 5 minutes after being removed from the heat to allow the juices to redistribute, ensuring maximum tenderness.
Common mistakes
A common error is crowding the slow cooker, which prevents even cooking and can lead to uneven textures. Always aim for a single layer of turkey. Another frequent mistake is opening the lid too frequently, which releases essential heat and steam, significantly increasing the total cooking time.
Additionally, failing to whisk the soup and broth mixture thoroughly can result in a lumpy sauce; ensure the liquid is smooth before pouring it over the assembled meat and cheese layers.
How to tell it’s done
The turkey is done when it reaches an internal temperature of 165°F (74°C) at its thickest point. The meat should be opaque throughout and fork-tender. The sauce will have thickened slightly and appear creamy with the cheese fully melted and incorporated.
If you notice any pinkness in the center, continue cooking for an additional 15 minutes before checking again, as internal temperatures can vary based on the specific shape and density of the tenderloins used.
