Equipment: Must-haves

• Slow cooker
• Cutting board
• Sharp knife

• Measuring spoons
• Instant-read thermometer

Equipment: Nice-to-haves

• Skillet (for searing and reducing sauce)
• Small bowl (for mixing sauce)
• Whisk
• Serving platter
• Kitchen twine (optional, to keep shape while cooking)

Ingredients

• 1 pork tenderloin (about 1 pound), trimmed
• 1/2 cup apple butter
• 2 tablespoons soy sauce
• 1 tablespoon Dijon mustard
• 1 tablespoon brown sugar (lightly packed)
• 1 clove garlic, minced
• 1/2 teaspoon smoked paprika
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• 1 teaspoon apple cider vinegar
• 1 tablespoon olive oil
• 1 small onion, thinly sliced
• 1 sprig fresh thyme (or 1/2 teaspoon dried thyme)
• 1 tablespoon cornstarch
• 1 tablespoon water
• 1 tablespoon unsalted butter (optional, for glossy finish)

Instructions

1. Pat the pork tenderloin dry with paper towel and season it with salt, pepper, and smoked paprika.
2. Heat the skillet over medium-high heat and add the olive oil.
3. Sear the pork tenderloin on all sides until a golden crust forms, using the tongs to turn it—this builds flavor and looks impressive with almost no extra effort.
4. Transfer the seared pork tenderloin to the slow cooker and nestle it on top of the sliced onion and thyme.
5. In the small bowl, whisk together the apple butter, soy sauce, Dijon mustard, brown sugar, minced garlic, and apple cider vinegar until smooth.
6. Pour the apple butter sauce over the pork tenderloin, making sure the sauce coats the top and sides.
7. Cover and cook on low in the slow cooker until the pork reaches the proper internal temperature, checking with the instant-read thermometer toward the end of the cook time.
8. When the pork tenderloin reaches the target temperature, remove it from the slow cooker and tent it lightly with foil to rest.
9. Pour the cooking juices into the skillet and bring them to a simmer over medium heat.
10. Whisk the cornstarch with water to make a slurry, then whisk the slurry into the simmering juices to thicken into a glossy sauce.
11. Stir in the optional butter for an extra-silky finish and taste to adjust seasoning.
12. Slice the rested pork tenderloin into medallions and spoon the thickened apple butter sauce over the top before serving.
