Equipment: Must-haves
- Slow cooker
- Skillet (preferably cast iron)
- Sharp knife
- Cutting board
- Mixing bowl
- Tongs
- Meat thermometer

Equipment: Nice-to-haves
- Kitchen twine
- Silicone spatula
- Mandoline (for even apple slices)
- Slotted spoon

Ingredients
- 1 pork loin (about 2 to 3 lb), trimmed
- 2 tablespoon butter (unsalted), for browning
- 1 apple (firm variety), cored and sliced
- 1 onion, thinly sliced
- 2 clove garlic, minced
- 1/4 cup brown sugar (packed)
- 1/4 cup apple cider
- 2 tablespoon Dijon mustard
- 1 teaspoon dried thyme
- 1 tablespoon olive oil
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 tablespoon apple cider vinegar
- 1 bay leaf
- 1 tablespoon cornstarch
- 1 tablespoon water

Instructions
- Pat the pork loin dry with paper towel and season it all over with salt and pepper.
- Heat the skillet over medium heat and melt the butter until it foams and the color turns nutty and golden.
- Add the apple slices and onion to the skillet and sauté briefly until they start to brown and smell irresistible.
- Stir in the garlic and let it get fragrant for just a moment so it doesn’t turn bitter.
- Transfer the browned apple and onion mix into the slow cooker and spread it into an even layer.
- Wipe the skillet clean, add the olive oil, and sear the pork loin on all sides until it has a golden crust.
- Place the seared pork loin on top of the apple and onion bed in the slow cooker.
- In the mixing bowl whisk together the brown sugar, apple cider, Dijon mustard, dried thyme, and apple cider vinegar until smooth.
- Pour the sauce over the pork loin and tuck the bay leaf beside the meat.
- Cover and cook on low until the pork reaches a safe temperature and is tender when pierced.
- When the pork is done, transfer it to a cutting board and tent it with foil to rest.
- Skim fat from the slow cooker juices with a spoon or slotted spoon, then pour the remaining juices into the skillet and bring to a simmer.
- Mix the cornstarch with water to make a slurry and whisk it into the simmering juices until the sauce thickens into a glossy gravy.
- Slice the pork loin against the grain and spoon the apple-butter gravy over each slice.
- Serve immediately with extra cooked apple on the side and smile like you planned this all along.

Good to Know
Timing and temp: Cook low and slow unless you like a chewy pork loin. Use a meat thermometer and remove the pork at the right internal temperature to keep it juicy.
That’s why a thermometer is not optional. Swap ideas: Use maple syrup in place of brown sugar for a deeper autumn vibe.
Add a pinch of cayenne if you want a tiny surprise. Serving suggestion: Plate slices with mashed potato or polenta and spoon the apple-butter gravy over everything.
A green vegetable brightens the plate and the mood. Make-ahead note: Leftovers are excellent.
Chill the pork with gravy, then reheat gently in a skillet. The gravy thickens in the fridge; thin with a splash of apple cider if needed.
Pro tips: Tie the pork with kitchen twine before searing if it’s uneven, so it cooks more uniformly. If you want more texture, crisp leftover slices under the broiler for a minute before serving.
Food safety: Resting is not optional. It lets juices redistribute so you don’t get a puddle of disappointment on the cutting board.
Enjoy the combo of browned butter and apple—comfort food that sounds fancy but is shockingly easy. And hey, you just out-cooked takeout without breaking a sweat.
