Ingredients
For the Turkey Tenderloin
- 3 lbs. turkey tenderloins (The four tenderloins in my photographs were approximately .75 lbs each.)
For the Marinade
- 1/2 c. packed brown sugar
- 1/2 c. whole grain mustard (I used Inglehoffer Original Stone Ground)
- 1 T. apple cider vinegar
- 1 tsp. cumin
- 1 tsp. black pepper
- 1/2 tsp. smoked paprika
- 1/2 tsp. garlic powder
- 1/2 tsp. kosher salt
How to Make Grilled Turkey Tenderloin with Brown Sugar and Whole Grain Mustard
Step 1: Prepare the Marinade
In a medium bowl, whisk together the brown sugar, whole grain mustard, apple cider vinegar, cumin, black pepper, smoked paprika, garlic powder, and kosher salt. Reserve 1/3 cup of this mixture to drizzle over the turkey before serving.
Step 2: Marinate the Turkey
Place the turkey tenderloins in a low and wide medium bowl or pan. Pour the remaining marinade over them and ensure they are completely coated. Cover with plastic wrap and refrigerate for 1 hour. After marinating, remove from the refrigerator and let sit at room temperature while heating the grill.
Step 3: Preheat the Grill
Heat your grill to high heat and ensure that the grates are scrubbed clean. Oil them by dipping a folded paper towel into canola oil and running it over the grates using tongs. After oiling, reduce the heat slightly to medium-high.
Step 4: Grill the Turkey Tenderloins
Place each turkey tenderloin on the grill with its beauty side facing down. Sear for about 4 minutes until you see beautiful charred grill lines. Carefully flip each tenderloin using a metal turner to avoid tearing. Lower heat to medium and continue grilling for about 8 minutes; rotate on one side after 5 minutes to maintain those beautiful grill marks. Finally, reduce heat to medium-low until the internal temperature reaches 160°F; expect about 40 minutes total grilling time depending on thickness.
Step 5: Rest and Serve
Once grilled, transfer tenderloins to a platter to rest for 5 minutes before slicing. Drizzle reserved marinade over sliced pieces before serving hot or warm.

Common Mistakes to Avoid
Grilling turkey tenderloin can be a delightful experience, but avoiding common pitfalls is essential for the best results. Here are some mistakes to watch out for:
- Not marinating long enough: Failing to marinate the turkey tenderloin for at least an hour can lead to a lack of flavor. Ensure you give it enough time in the marinade for optimal taste.
- Ignoring grill temperature: Grilling on high heat without preheating can cause uneven cooking. Always preheat your grill and adjust the temperature as needed to achieve even cooking.
- Overcooking the turkey: Turkey can dry out if overcooked. Use a meat thermometer to check for doneness at 160°F for juicy, tender meat.
- Skipping resting time: Cutting into the turkey right after grilling allows juices to escape, leading to dryness. Let it rest for a few minutes before slicing to keep it juicy and flavorful.
- Not using a non-stick spray or oil: If you skip oiling your grill grates, your turkey may stick. Always make sure to oil the grates before grilling to prevent sticking.
