Before you start
Before starting, verify that the turkey tenderloins are fully thawed if they were previously frozen. Clear your countertop of any unnecessary items to provide a clean workspace. Gather all measuring tools and ingredients to ensure a seamless preparation process.
Ensure your slow cooker is clean and that the insert is securely positioned. If your tenderloins have any excess silverskin or fat, trim it off with a sharp knife to ensure the best texture. Set out the mustard, syrup, and pecans so they are within easy reach when you begin assembling the dish in the slow cooker.

Instructions
Assembly
- Prepare the slow cookerPlace the raw turkey tenderloins into the bowl of your slow cooker. Ensure they are laid out in a single layer to promote even cooking throughout the process.Look for Turkey is arranged in the slow cooker base.Tip Ensure the turkey is completely thawed if using frozen tenderloins to maintain food safety.
The raw turkey tenderloins rest in an even, single layer flat along the bottom of the slow cooker insert without overlapping. The surface of the meat is cool to the touch and fully thawed, presenting a clean base ready to receive the glaze. Double check that all ingredients and measuring tools are organized within reach before continuing.
Glazing
- Add the glaze ingredientsSpoon the Dijon mustard over the turkey tenderloins. Scatter the chopped pecans over the top, then pour the maple syrup evenly across the turkey and nuts to coat them.Look for All ingredients are added to the slow cooker.Tip Distribute the mustard evenly to ensure every part of the turkey receives the flavor.
The rich mustard is distributed across the tenderloins, crowned with an even scatter of chopped pecans and a glossy blanket of maple syrup. The sweet, pungent aroma of maple and Dijon fills the air. Verify that the lid is securely seated on the slow cooker to seal in moisture before starting the heat cycle.
Slow Cooking
- Cook and finishCover the slow cooker and set to low heat for 4 hours. Once finished, ensure the internal temperature of the turkey reaches 165°F (74°C). Remove the turkey and let it rest for at least 3 minutes, up to 5 minutes, before slicing.Look for Turkey is tender and reaches internal temperature.Safe temperature 165°F (74°C) internal temperature (poultry)Tip Use a digital meat thermometer inserted into the thickest part of the tenderloin to check the temperature.
The slow cooker lid is warm, and steam rises carrying an aromatic blend of toasted nuts and caramelized maple syrup. The tenderloins appear plump, glossy, and fully opaque, with a food thermometer reading at least 165°F (74°C) in the thickest section. Allow the meat to rest at least 3 minutes on a board before slicing into medallions.
Common mistakes
A common mistake is overcrowding the slow cooker, which can lead to uneven cooking; ensure the tenderloins are in a single layer. Another error is failing to reach the safe internal temperature of 165°F (74°C), which is essential for poultry.
Avoid lifting the lid of the slow cooker frequently during the cooking process, as this releases heat and moisture, significantly increasing the total cooking time and potentially affecting the tenderness of the meat.
Finally, do not skip the resting period, as cutting the meat too soon will cause the juices to escape, resulting in a drier texture.
How to tell it’s done
The turkey is done when it is opaque throughout and reaches an internal temperature of 165°F (74°C). Use a meat thermometer inserted into the thickest part of the tenderloin to verify this reading. The meat should be firm to the touch but still tender, and it should slice easily into clean medallions.
The glaze should appear glossy and slightly thickened, coating the meat thoroughly. Always allow the cooked turkey to rest on a cutting board for at least 3 minutes, or up to 5 minutes, before slicing, as this helps the juices redistribute throughout the meat, ensuring each medallion remains moist and flavorful.
- Poultry: 165°F (74°C) in the thickest part
- Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
