Before you start
Before beginning, ensure that the slow cooker vessel is clean and dry. Prepare the ingredients by slicing the apples into uniform wedges to ensure they cook evenly.
If the turkey tenderloins have any excess silver skin or fat, trim it away with a sharp knife to ensure the best texture. Have your measuring tools ready to accurately portion the sugar, cinnamon, and cider for the best flavor balance.

Ensure the meat is arranged in an even layer to promote consistent cooking throughout the process.Look for The turkey should be laid flat at the bottom of the cooker.Tip Avoid overcrowding the slow cooker to ensure even heat distribution.
The turkey is placed in the slow cooker, creating a stable base for the remaining ingredients. The apples are layered on top, and the seasonings are added. Everything should look neat and ready for the slow-cooking process to begin.
Flavor infusion

Sprinkle the brown sugar and ground cinnamon over the apples, then pour the apple cider over the entire mixture.Look for The sugar and cinnamon should be distributed as evenly as possible.Tip Layering the ingredients allows the flavors to meld as the turkey cooks.
As the cooking progresses, the apple cider and spices begin to combine with the juices released by the apples and turkey. The kitchen will begin to smell warm and fragrant, and the liquid level will slightly rise as the fruit softens.
Final cook and rest
- Cook and serveCover and cook on low for 4 hours until the turkey reaches an internal temperature of 165°F (74°C). Remove the turkey and let it rest for at least 5 minutes before slicing into medallions to serve with the cooked apples.Look for The turkey should be opaque and reach the required temperature.Safe temperature 165°F (74°C) internal temperature (poultry)Tip Use a meat thermometer to check the thickest part of the tenderloin.
The turkey has reached the correct internal temperature. The apples are tender and have formed a light, syrupy consistency. After resting, the turkey is ready to be sliced into medallions and served with the spiced fruit topping.
Common mistakes
A common mistake is overcooking the turkey, which can lead to a dry, stringy texture even in a slow cooker. To avoid this, start checking the temperature toward the end of the suggested cooking time.
Another error is failing to trim the meat properly; while tenderloins are lean, removing connective tissue ensures a better mouthfeel.
Finally, ensure the slow cooker lid is kept closed during the cooking cycle to maintain the necessary temperature and moisture levels for safe and efficient cooking.
How to tell it’s done
The turkey is ready when it reaches an internal temperature of 165°F (74°C) as measured by a reliable meat thermometer inserted into the thickest part of the tenderloin. At this stage, the meat should be opaque throughout and pull apart easily with a fork.
It is essential to let the turkey rest for at least 5 minutes before slicing, as this allows the juices to redistribute, ensuring every slice remains moist and flavorful.
