- Wooden spoon
- Paper towels
Equipment: Nice-to-haves
- Skillet for searing (optional)
- Kitchen twine (optional)
- Meat thermometer (optional)
- Apple corer or slicer (optional)
Ingredients
- 1 pork tenderloin (about 1 to 1.5 lbs)
- 1 apple, cored and sliced
- 3 clove garlic, minced
- 2 sprig fresh rosemary
- 1/2 cup apple cider
- 2 tbsp brown sugar
- 1 tbsp olive oil
- 1 small onion, sliced
- 1 tbsp Dijon mustard
- 1 tsp salt
- 1/2 tsp black pepper
- 1 tbsp butter (optional, for finishing)
- 1 tsp cornstarch (optional, for thickening sauce)
- 1 tbsp water (for cornstarch slurry)
Instructions
- Pat the pork tenderloin dry with paper towels like you’re giving it a tiny spa treatment.
- Season the pork evenly with salt and pepper on all sides so flavor gets personal.
- If you have a skillet, heat olive oil until shimmering and sear the pork on all sides until golden; this step adds flavor but is optional if you’re short on time.
- Transfer the pork to the slow cooker using tongs and try not to admire your reflection in the pot.
- In a mixing bowl, combine apple cider, brown sugar, minced garlic, Dijon mustard, and a pinch of salt and pepper to make a sticky, tangy glaze.
- Place the sliced apple and onion in the slow cooker around and on top of the pork so they can cozy up together.
- Nestle the rosemary sprig on top of the pork so its aroma slowly sneaks into everything.
- Pour the glaze over the pork and apples, being sure to get some under the pork too so every bite gets attention.
- Cover the slow cooker and set it to low for a long, slow cook that makes the meat tender and juicy or set to high for a faster finish if you’re impatient.
- Halfway through cooking, spoon some cooking liquid over the pork to keep it moist and to make you feel like a fancy home chef.
- Check the pork toward the end of the cook time with a meat thermometer if you have one; you’re aiming for safe, pleasant doneness.
- When the pork is done, carefully remove it and tent it with foil to rest so the juices don’t bolt out like a startled horse.
- If you like a glossy sauce, skim excess fat from the slow cooker juices, then whisk cornstarch and water into a slurry and stir it into the juices over medium heat in a skillet until slightly thickened.
- Return the juices to the slow cooker or spoon the thickened sauce over the pork for serving so nobody misses out on saucy goodness.
- If you used kitchen twine to keep the pork tidy while cooking, remove it before slicing unless you like chewing string (don’t).
- Slice the pork into medallions on the cutting board against the grain so each bite is tender and easy to eat.
- Arrange slices on a platter with the cooked apple and onions, drizzle with sauce, and dot with butter if you want a rich finish.
- Serve immediately with your favorite side and watch everyone act like you’ve been cooking professionally this whole time.
What Else You Should Know
Timing: Low-and-slow will give you the best texture; high setting is fine in a pinch. Thickening: That cornstarch slurry is a small trick that turns cooking liquid into a silky sauce.
Swap ideas: Use a pear instead of an apple for a softer, sweeter twist. Serving: This pork loves mashed potato, creamy polenta, or buttered rice to soak up the sauce.
Make-ahead: The pork holds well in the fridge and slices reheat nicely; store sauce separately for best texture. But here’s the catch!
if you overcook it, even the best spices can’t save it—so rest and check temp. That’s why a meat thermometer is a tiny device that pays dividends in juicy bites.
Final tip: use fresh rosemary for brightness; dried works in a pinch, but fresh makes you look like you had a plan.
