- Tongs

Equipment: Nice-to-haves
- Cast-iron skillet (for optional sear)
- Meat thermometer
- Ladle
- Serving platter

Ingredients
- 1 pork tenderloin (about 1 to 1.5 lb)
- 1 apple (firm variety like Honeycrisp or Granny Smith), cored and sliced
- 1 onion (small), sliced
- 1 clove garlic, minced
- 1/2 cup apple cider
- 2 tbsp Dijon mustard
- 1 tbsp brown sugar
- 1 tbsp olive oil
- 1 tsp dried thyme
- Salt to taste
- Black pepper to taste
- 1 tbsp cornstarch
- 2 tbsp cold water
- Fresh parsley for garnish (optional)

Instructions
- Pat the pork tenderloin dry and season it all over with salt, pepper, and dried thyme.
- If you want deeper flavor, heat a cast-iron skillet with olive oil and quickly sear the pork on all sides until browned; this step is optional but delightful.
- Place sliced apple and sliced onion in the bottom of the slow cooker to make a cozy bed for the pork.
- Nestle the pork tenderloin on top of the apple and onion bed like it’s taking a comfy nap.
- Whisk together apple cider, Dijon mustard, brown sugar, and minced garlic in a small bowl to make the saucy magic.
- Pour the sauce over the pork and apples, covering everything evenly so the slow cooker does its job.
- Cover and cook on low until the pork is tender and the internal temperature reaches the safe mark; use a meat thermometer if you have one.
- When the pork is done, carefully transfer it to a cutting board and tent with foil to rest while you finish the sauce.
- Skim any excess fat from the slow cooker liquid and then whisk the cornstarch with cold water to make a slurry.
- Stir the slurry into the slow cooker liquid and cook on high for a few minutes until the sauce thickens and becomes glossy.
- Slice the pork tenderloin across the grain into medallions and return the slices to the slow cooker to warm in the sauce briefly.
- Use tongs to plate the pork with apples and onions and spoon plenty of thickened sauce over the top.
- Garnish with fresh parsley if using, and serve immediately with your favorite side.
- If you used a skillet to sear, don’t forget to clean it before it gives you the silent treatment.
What Else You Should Know
Tips:
Pat the pork dry before seasoning to help with browning; dry skin = better crust. If you skip the sear, the dish is still delicious—searing is just the polish.
Use a meat thermometer to check doneness; pork is safe and juicy at the correct temperature. Variations:
Swap apple cider for apple juice if that’s what’s hiding in your fridge.
Add a splash of balsamic vinegar for a tangy twist. Stir in a pinch of cinnamon for apple-pie vibes without the pastry.
Serving suggestions:
Serve this with mashed potato, buttered noodle, or a single roasted vegetable to keep things simple. A slice of crusty bread is perfect for mopping up the sauce.
Storage:
Store leftovers in an airtight container in the fridge and use within a couple of days. Reheat gently in a skillet or microwave and add a splash of water if the sauce tightens.
Final note:
This recipe leans into current trends: simple one-pot comfort, seasonal fruit pairing, and minimal hands-on time. It’s perfect for busy evenings and makes you look like a dinner hero with very little effort—and that, my friend, is practically culinary magic.
