This recipe is designed for maximum flavor with minimal effort. The sear is highly recommended for the best results!
Gather Your Ingredients:
For the Pork & Rub:
- 1 (1.5 – 2 lb) pork tenderloin
- 1 tablespoon olive oil
- 1 teaspoon garlic powder
- 1 teaspoon dried thyme (or ½ tsp rosemary)
- ½ teaspoon salt
- ¼ teaspoon black pepper
For the Legendary Sauce:
- ⅓ cup pure maple syrup
- ¼ cup Dijon mustard
- 2 tablespoons soy sauce (or coconut aminos)
- 2 tablespoons apple cider vinegar
- 3 cloves garlic, minced
- 1 tablespoon cornstarch (for thickening at the end)
The Simple, Foolproof Method:
Step 1: The Flavor-Building Sear (Don’t Skip This!)
- Pat the pork tenderloin completely dry with paper towels. This is crucial for getting a good sear.
- Rub the tenderloin all over with the olive oil, then season evenly with the garlic powder, thyme, salt, and pepper.
- Heat a skillet over medium-high heat. Sear the pork for 1-2 minutes on all sides, until you have a beautiful golden-brown crust. This step adds a ton of flavor!
Step 2: The Slow Cooker Assembly
- Place the seared pork tenderloin into your slow cooker.
- In a small bowl, whisk together the maple syrup, Dijon mustard, soy sauce, apple cider vinegar, and minced garlic.
- Pour this sauce mixture over the pork in the slow cooker.
Step 3: The “Set It and Forget It” Magic
- Cover and cook on LOW for 4-5 hours or on HIGH for 2-3 hours. The pork is done when it reaches an internal temperature of 145°F (63°C) at the thickest part. Avoid overcooking!
Step 4: The Glossy, Restaurant-Quality Finish
- Once cooked, carefully transfer the pork to a cutting board and tent it loosely with foil. Let it rest for 10 minutes. This allows the juices to redistribute, ensuring every slice is moist.
- Pour the remaining liquid from the slow cooker into a small saucepan. In a separate cup, make a “slurry” by mixing the 1 tablespoon of cornstarch with 2 tablespoons of cold water until smooth.
- Bring the sauce to a simmer and whisk in the cornstarch slurry. Cook for 1-2 minutes, whisking constantly, until the sauce thickens into a rich, glossy glaze.
