Equipment: Nice-to-haves
- Cast-iron skillet (for searing)
- Kitchen twine (for trussing)
- Immersion blender (for a silky sauce)
- Pastry brush (for glazing)
Ingredients
- 1 pork tenderloin (about 1 lb), trimmed
- 1 apple, peeled, cored, and chopped
- 1/2 cup applesauce (unsweetened)
- 1/2 cup apple cider
- 1 tablespoon olive oil
- 2 cloves garlic, minced
- 1 tablespoon fresh rosemary, chopped
- 1 teaspoon dried thyme
- 1 tablespoon Dijon mustard
- 1 tablespoon brown sugar
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/4 teaspoon red pepper flakes (optional)
- 1 tablespoon cornstarch
- 2 tablespoons cold water
- Fresh parsley, chopped (for garnish, optional)
Instructions
- Pat the pork tenderloin dry and season it all over with salt and pepper to help the surface get a nice crust.
- Heat the cast-iron skillet over medium-high heat and add the olive oil until it shimmers.
- Sear the tenderloin on all sides until golden brown to lock in juices, then transfer it briefly to a plate.
- Place the chopped apple and minced garlic in the mixing bowl and stir in applesauce, apple cider, Dijon mustard, brown sugar, rosemary, thyme, and red pepper flakes until combined.
- Pour half of the apple-herb mixture into the bottom of the slow cooker and spread it into an even layer.
- Lay the seared tenderloin on top of the sauce in the slow cooker and then spoon the remaining apple-herb mixture over the top.
- If desired, use the kitchen twine to gently truss the tenderloin so it cooks evenly; this is optional but neat.
- Cover and cook on low until the internal temperature reaches a safe and juicy point, checking with the instant-read thermometer.
- Carefully remove the tenderloin to a cutting board and tent it loosely while you finish the sauce in the slow cooker.
- Skim any large fat blobs from the surface of the sauce with the wooden spoon and then whisk the cornstarch into cold water to make a slurry.
- Stir the slurry into the sauce in the slow cooker and cook on high for a few minutes until the sauce thickens and becomes glossy.
- For a velvety texture, use the immersion blender right in the slow cooker to puree the sauce to your preferred smoothness.
- Brush a little sauce over the rested tenderloin with the pastry brush for a shiny finish.
- Slice the tenderloin into medallions, spoon extra sauce over the top, and garnish with chopped parsley before serving.
What Else You Should Know
Timing tip: The pork tenderloin will cook best on low until the center reaches the ideal temperature; pulling it a few degrees under target is smart because carryover heat finishes the job. Doneness guide: Aim for a juicy final temp rather than overcooking; use your instant-read thermometer to check.
Variation: Swap fresh rosemary for sage or a pinch of smoked paprika for a warmer profile. Make-ahead: The sauce keeps well in the fridge and actually tastes deeper the next day, so double the sauce if you like leftovers.
Serving suggestion: Serve with creamy mashed potato, roasted vegetable, or a simple green to balance the sweetness. Quick fix: If you prefer a thicker glaze, reduce the sauce on the stove in a skillet after removing the tenderloin.
Final note: This recipe celebrates one pork tenderloin and a single apple to keep things simple and fridge-friendly—no juggling multiple items or complicated prep. Enjoy the hug-in-a-bowl feeling, but on a plate.
