Why You’ll Love This Recipe
- Hands-off cooking: You mostly load the slow cooker and let it work.
- Simple ingredients: Pork, apples, cinnamon, and a few pantry staples.
- Tender texture: Slow cooking keeps the pork moist and easy to slice.
- Family-friendly flavor: The mild sweetness appeals to both kids and adults.
Ingredients
- 1 1/2 lb (680 g) pork tenderloin
- 2 medium apples, such as Gala or Fuji, peeled, cored, and sliced into 1/2-inch (1 cm) wedges
- 1/2 cup (120 ml) apple juice or low-sodium chicken broth
- 2 tbsp (25 g) packed brown sugar
- 1 tsp ground cinnamon
- 1 tsp kosher salt
- 1/2 tsp black pepper
- 1 tsp garlic powder (optional)
- 1 tbsp (8 g) cornstarch mixed with 1 tbsp (15 ml) cold water (optional, for thickening)
Ingredient Notes
Tart-sweet apples like Granny Smith or Honeycrisp hold their shape well, while softer apples break down into a smoother sauce. Apple juice adds sweetness, and broth gives the pork a more savory base. Brown sugar helps the sauce turn glossy and caramel-colored.
Equipment You’ll Need
- Slow cooker (4-quart or larger)
- Cutting board and sharp knife
- Meat thermometer
- Small bowl and spoon for the cornstarch slurry
How to Make Slow-Cooker Apple Cinnamon Pork Tenderloin
- Season the pork. Pat the tenderloin dry with paper towels. Mix the salt, pepper, cinnamon, brown sugar, and garlic powder in a small bowl, then rub the mixture over all sides of the pork.
- Layer the slow cooker. Scatter the apple wedges across the bottom of the slow cooker. Place the seasoned pork on top, then pour in the apple juice or broth around the meat, not over the top, so the seasoning stays on the pork.
- Cook on low. Cover and cook on low for about 3 to 4 hours. Cooking times vary by slow cooker, so start checking at around 3 hours.
- Check the internal temperature. Insert a meat thermometer into the thickest part of the pork. The pork is done when it reaches 145°F (63°C), followed by a short rest. The meat should be pale pink in the center, and the juices should run clear.
- Rest the pork. Transfer the pork to a cutting board and let it rest for about 5 to 10 minutes. This helps the juices settle back into the meat.
- Make the sauce (optional). Skim any excess fat from the cooking liquid. For a thicker sauce, pour the liquid and apples into a small saucepan over medium heat, stir in the cornstarch slurry, and simmer for 1 to 2 minutes until glossy and slightly thickened.
- Slice and serve. Cut the pork into 1/2-inch (1 cm) slices and spoon the apples and sauce over the top.
Pro Tips for the Best Results
- Pat the pork dry before seasoning so the rub sticks and the outside develops more flavor.
- Avoid overcooking. Pork tenderloin is lean and can dry out quickly, so use a thermometer rather than guessing.
- Keep the lid closed while cooking, since each peek adds time and heat.
- Use firm apples so they don’t turn to mush during the long cook.
- Let the pork rest before slicing to keep the slices juicy.
Common Mistakes to Avoid
Using a pork roast instead of tenderloin. Pork tenderloin is much smaller and leaner, so it needs far less time than a shoulder roast. Check it early.
Adding too much liquid. The apples and pork release moisture as they cook. Too much liquid can dilute the flavor and make the sauce thin.
Skipping the thermometer. Slow cookers vary, and the color of the meat is not a reliable sign of doneness.
Variations and Substitutions
- Maple version: Replace the brown sugar with 1 tbsp maple syrup.
- Onion add-in: Place 1/2 sliced yellow onion under the pork for extra savory flavor.
- Dijon glaze: Stir 1 tsp Dijon mustard into the finished sauce for a slightly tangy taste.
Serving Suggestions
Serve the pork with mashed potatoes, roasted green beans, or wild rice to soak up the sauce. A simple green salad with a light vinaigrette also works well. For drinks, try sparkling apple cider or iced tea.
Storage and Reheating
Store leftover pork and apples in an airtight container in the refrigerator within 2 hours of cooking. Leftovers are generally best eaten within 3 to 4 days. To reheat, warm slices gently in a covered dish with a splash of the sauce or broth until heated through. Freezing is possible, though the apples may soften more after thawing.
Frequently Asked Questions
Can I cook this pork tenderloin on high?
Yes, but cooking time will be shorter, usually around 1.5 to 2 hours. Check the internal temperature early to avoid overcooking.
Can I use pork loin instead?
Pork loin is larger and may need a longer cook time. Use a thermometer and cook until it reaches 145°F (63°C), then rest the meat before slicing.
Why did my pork turn out dry?
Overcooking is the most common cause. Pork tenderloin is lean, so it should be checked early and removed once it reaches 145°F (63°C).
Can I make this ahead of time?
You can season the pork the night before and refrigerate it in the sealed container. Add it to the slow cooker the next day.
