  • 2 tablespoons butter, cut into small pieces
  • 1 cup apple cider or apple juice Apple cider gives more flavor.
  • 1 tablespoon Dijon mustard

  • 1 teaspoon cinnamon (optional) Adds a cozy flavor.
  • Salt and pepper to taste
  • Cornstarch slurry (optional for thickening sauce) Mix with water to thicken sauce at the end.

Method
 

Preparation
  1. Season the pork tenderloin all over with salt and pepper.
  2. Optional: Sear the pork in a hot pan with a splash of oil for 5 minutes to enhance flavor and appearance.
  3. Layer the sliced apples and onion in the bottom of the slow cooker.
  4. Whisk together the apple cider, Dijon mustard, brown sugar, and cinnamon, then pour over the fruits.
  5. Place the pork on top and dot with butter.
Cooking
  1. Cover and cook on low for about 2.5 to 4 hours, depending on thickness.
  2. Aim for an internal temperature of 145°F, then let rest for 5 to 10 minutes before slicing.
  3. If the sauce is thin, remove the pork, turn the cooker to high, stir in the cornstarch slurry, and let bubble for 5 to 10 minutes until thickened.

Notes

Serve with mashed potatoes, rice, or buttered noodles. Leftovers taste great and can be stored in the fridge for 3-4 days or frozen for up to 2 months. Reheat gently to maintain tenderness.
