Ingredients

Crockpot Turkey Tenderloin

1.5 lbs Turkey breast tenderloins these come packaged with two and are already pre-brined
1/2 tbsp 24 Herbs Sprinkle Seasoning (Salt-free)
1/2 tsp Onion Powder
1/2 tsp Smoked Paprika
1/4 tsp Xanthan Gum optional, for gravy

Turkey Tenderloin Marinade

2 tbsp Garlic minced
1/2 tbsp 24 Herbs Sprinkle Seasoning (Salt-free)
1/2 cup Olive Oil
1/4 tbsp Lemon Juice
1/2 tsp Natural Ancient Sea Salt
1/2 tsp Granular Sweetener or any 1:1 sugar substitute

Instructions

Pat Turkey tenderloins dry with a paper towel.
Add the ingredients for the marinade to a bowl. Whisk to incorporate.
Add the Turkey tenderloin to the bowl with the marinade, and cover. Marinate for up to 24 hours - if short on time, head right to the slow cooker.
Mix the spices for the meat (herb seasoning, onion powder, smoked paprika) in a small bowl - this helps with applying the spice mix evenly over the meat.
Add the Turkey tenderloin and all the contents of the marinade to the slow cooker. Sprinkle the tops of the Turkey tenderloin with the spices.
Slow Cook on Low for 3-3.5 hours (or until the center of the meat is 165 degrees.
Remove the turkey and allow to rest for 5-10 minutes before cutting
For gravy: whisk in the Xanthan gum, turn the slow cooker to high, cook uncovered until the gravy starts to thicken (5-10 minutes)

Notes

Marinate only if it fits your schedule: You can let the turkey sit in the marinade ahead of time for more flavor, but it is not required. The turkey cooks low and slow in the marinade, so you can add everything to the crockpot and start cooking right away.
Use a meat thermometer: Turkey tenderloin is lean and can dry out if overcooked. Start checking around 3 hours and remove it once the center reaches 165°F.
Adjust for pre-marinated tenderloins: If your turkey tenderloin is already seasoned or marinated, use the same cooking method and adjust the added marinade or spices based on the flavor in the package.
Thicken the juices: Use xanthan gum, cornstarch, or another simple thickener to turn the slow cooker juices into a quick gravy or glaze. You can also spoon the juices over the sliced turkey as-is.
Let it rest before slicing: Rest the turkey for a few minutes after cooking so the juices settle back into the meat.
