- Slotted spoon
- Carving knife
- Serving platter

Ingredients
- 1 pork tenderloin (about 1 lb), trimmed
- 1 tablespoon olive oil (for searing)
- 1 apple, cored and sliced (Granny Smith or Honeycrisp work great)
- 1 small onion, thinly sliced
- 2 cloves garlic, minced
- 1/2 cup apple cider
- 2 tablespoons Dijon mustard
- 1 tablespoon brown sugar (or maple syrup if you want fancy)
- 1 sprig fresh thyme (or 1/4 teaspoon dried thyme)
- 1/2 teaspoon smoked paprika
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1 tablespoon cornstarch
- 2 tablespoons cold water (for slurry)
- 1 tablespoon butter (optional, for finishing sauce)

Instructions
- Pat the pork tenderloin dry and season it all over with salt, pepper, and smoked paprika.
- Heat the skillet over medium-high heat and add the olive oil until shimmering.
- Sear the pork on all sides until golden brown so the exterior locks in flavor and looks proud.
- Transfer the seared pork into the slow cooker and tuck it into the center like it owns the place.
- Scatter the apple slices and onion around the pork so they get cozy during the slow cook.
- Add minced garlic, Dijon mustard, apple cider, brown sugar, and thyme to the slow cooker and spoon a little of the liquid over the pork.
- Cover and cook on low until the pork is tender and the internal temperature reaches the safe doneness point using a meat thermometer.
- When the pork is nearly done, whisk the cornstarch and cold water in the small bowl to make a smooth slurry.
- Carefully remove the pork to a cutting board and tent it with foil to rest while you finish the sauce.
- Turn the slow cooker to high and stir in the cornstarch slurry, letting the sauce bubble until it thickens slightly.
- Stir in butter if using to give the sauce a glossy finish and adjust seasoning to taste.
- Slice the rested pork across the grain into medallions and arrange them on a platter.
- Spoon the warm apple-onion sauce over the pork and serve immediately with your favorite side.
What Else You Should Know
Tips: Searing the pork is optional, but it adds flavor and a nice color—think of it as a tiny effort that pays dividends. Use a meat thermometer to check doneness; the safe internal temperature is the important number.
Resting the pork before slicing keeps juices locked in so each bite is moist and proud. Variation: Swap the apple cider for apple juice or a splash of white wine for a different flavor profile.
If you prefer savory over sweet, cut the brown sugar in half and add a splash of soy sauce for umami. Serving suggestion: This dish loves mashed potato, roasted root vegetable, or a bed of wild rice.
A simple green salad brightens the plate and makes you look balanced. Storage: Store leftovers in an airtight container for up to three days.
Reheat gently in a skillet with a splash of broth to avoid drying out the pork. Quick note: If the sauce is too thin, simmer it uncovered in the slow cooker on high until reduced.
If it’s too thick, stir in a little apple cider to loosen. That’s why a little patience and a tiny bowl for the slurry are your friends.
Final pep talk: You just made a dinner that smells like effort but tastes like genius. Serve with confidence and maybe warn your neighbor to bring a fork.
