Ingredients
- 1 pork tenderloin (about 1 lb), trimmed
- 1 apple (Fuji or Honeycrisp), cored and sliced
- 1 onion (yellow), thinly sliced
- 2 tbsp unsalted butter
- 1/3 cup apple butter
- 1/4 cup chicken broth
- 1 tbsp Dijon mustard
- 1 tbsp brown sugar
- 1 tsp apple cider vinegar
- 1 garlic clove, minced
- 1 sprig fresh thyme
- 1/2 tsp salt
- 1/4 tsp black pepper
- 1 tsp cornstarch (optional, for thickening)
- 1 tbsp cold water (for slurry)
- 1 tsp olive oil (for searing)
Instructions
- Pat the pork tenderloin dry and season it with salt and pepper so it doesn’t feel ignored.
- Heat a heavy skillet over medium-high heat and add a splash of olive oil until it shimmers.
- Sear the pork on all sides until golden brown; this builds flavor and gives the tenderloin some personality.
- Transfer the pork to the slow cooker and set it aside like a VIP guest.
- In the same skillet, lower the heat, add butter, then sauté the sliced onion until it softens and sweetens.
- Toss in the apple slices and cook briefly until they start to caramelize; if your kitchen smells amazing, that’s normal.
- Stir in the minced garlic just until fragrant; don’t let it burn unless you enjoy bitterness as a spice.
- In a small bowl whisk together apple butter, chicken broth, Dijon mustard, brown sugar, apple cider vinegar, and the thyme sprig to form a glossy sauce.
- Pour the sauce and the soft apple-onion mixture over the pork in the slow cooker so everything can get cozy together.
- Cover and cook on low until the pork reaches a safe and juicy internal temperature; use the meat thermometer to check doneness.
- When the pork is done, remove it to a serving platter and let it rest so the juices settle and you don’t scare your tongue.
- Use a slotted spoon to transfer the apple and onion from the slow cooker into the skillet with the cooking liquid.
- Simmer the cooking liquid in the skillet to concentrate flavor, then whisk in a cornstarch slurry if you prefer a thicker glaze.
- Brush the warm, glossy sauce over the rested pork with the basting brush so every slice gets some love.
- Slice the tenderloin against the grain and spoon extra apple-onion butter sauce over each slice before serving.
What Else You Should Know
Timing tip: Cooking time will vary based on slow cooker model and tenderloin size; low heat usually yields the juiciest result. Check temperature: Aim for an internal temperature of 145°F for tender, slightly pink pork.
Use that meat thermometer like it’s your new best friend. Variation: Swap apple butter for peach or apricot preserves if you want a fruity twist.
Serving suggestion: Serve sliced pork over mashed potato, creamy polenta, or buttered egg noodles to catch every drop of sauce. Storage: Leftover pork keeps well in the fridge for a few days and makes a shout-worthy sandwich with extra apple-onion butter.
Pro tip: If you like a caramelized finish, pop the sliced pork under a hot broiler for a minute or two after glazing — watch it like a hawk. Enjoy this low-effort, high-reward dish that proves crock pot cooking can be elegant and comforting at the same time.
