Before you start
Before beginning, ensure all ingredients are gathered and measured. If the parmesan cream sauce was made ahead, ensure it has been stored properly in the refrigerator and brought to room temperature for no more than 30 minutes before starting.
Prepare the slow cooker by placing it on a stable, heat-resistant surface away from the edge of the counter. Have a clean cutting board and a sharp knife ready for when the turkey is finished resting and ready to be sliced.

The aroma of herbs and cheese begins to fill the kitchen as the ingredients are layered, creating a visually appealing foundation for the long, slow cook ahead.
Cooking and Final Resting
- Slow Cook and ServeCover the slow cooker and cook on low for 4 hours until the turkey reaches an internal temperature of 165°F (74°C). Allow the meat to rest for 5 minutes before slicing and serving.Look for The turkey is opaque throughout and the sauce is bubbling and thickened.Safe temperature 165°F (74°C) internal temperature (poultry)Tip Use an instant-read meat thermometer to ensure the turkey is safely cooked to the required internal temperature.
The turkey is fully cooked, tender, and coated in a rich, thickened sauce. After resting for five minutes, the meat is ready to be carved. The final dish should be steaming, fragrant, and perfectly set, with the sauce clinging to the tender slices of turkey.
Common mistakes
A common mistake is overcooking the turkey, which can lead to a stringy texture. Always use a thermometer to check the temperature rather than relying solely on timing.
Another mistake is crowding the slow cooker too much; ensure the tenderloins are in a single layer for uniform heat distribution. Finally, avoid lifting the lid during the first few hours of cooking, as this lets out essential heat and extends the total cooking time significantly.
How to tell it’s done
The turkey is done when it reaches an internal temperature of 165°F (74°C) as measured by a meat thermometer inserted into the thickest part of the tenderloin.
The meat should be opaque and tender, pulling apart easily with a fork. The sauce will have thickened slightly and appear glossy with the sun-dried tomatoes softened and fully incorporated into the creamy base.
