Place the pork tenderloins in the slow cooker.
In a small bowl, whisk together the maple syrup, Dijon mustard, soy sauce, apple cider vinegar, minced garlic, salt, and pepper.
Pour the maple Dijon mixture over the pork tenderloins, ensuring they are well coated.
Cover and cook on low for 6-8 hours or until the pork is tender and cooked through.
Once cooked, remove the pork from the slow cooker and let it rest for a few minutes before slicing.
Serve the sliced pork with the sauce from the slow cooker drizzled over the top.
Variations & Tips
For a bit of heat, add a teaspoon of crushed red pepper flakes to the sauce mixture. If you prefer a thicker sauce, remove the pork once cooked and transfer the sauce to a saucepan. Simmer on the stove until it reduces to your desired consistency. You can also substitute honey for maple syrup if you prefer a different kind of sweetness. For a more herbaceous flavor, add a teaspoon of dried thyme or rosemary to the sauce.
