A pork tenderloin simmered all afternoon in sweet-tart cranberry sauce turns meltingly tender, the sauce deepens to a glossy burgundy, and your house smells like the holidays. This slow cooker cranberry pork tenderloin looks like you worked far harder than you did.
The base method never changes, but the sauce can lean classic, citrusy, spicy, herby, or cider-sweet. Below are five variations on one reliable technique. Each feeds four, takes about ten minutes of hands-on prep, and lets the slow cooker handle the rest.
Why You’ll Love This Slow Cooker Cranberry Pork Tenderloin
Pork tenderloin is one of the leanest cuts of pork, which also makes it easy to dry out in the oven. The slow cooker solves that problem: gentle, moist heat surrounds the meat for hours, tenderizing it without a hot oven’s harsh blast. The cranberry sauce adds moisture plus bright acidity that cuts the pork’s richness. It is also low-effort, and leftovers reheat beautifully over rice or mashed potatoes.
Ingredients You’ll Need
Every variation starts with the same foundation:
- 2 pork tenderloins (about 1 pound each), silver skin trimmed
- 1 tablespoon olive oil
- 1 teaspoon kosher salt
- 1/2 teaspoon black pepper
- 1 (12-ounce) bag fresh cranberries, or 1 can (14 ounces) whole-berry cranberry sauce
- 1 small yellow onion, thinly sliced
- 2 cloves garlic, minced
Each variation adds its own sauce ingredients, listed below. If you use canned cranberry sauce, halve any added sugar, since it is already sweetened.
How to Make Slow Cooker Cranberry Pork Tenderloin
The method is identical for all five versions. Pat the tenderloins dry, season, and sear in olive oil over medium-high heat, 2 to 3 minutes per side. Searing is not about sealing in juices — that is a myth — but about flavor: the Maillard reaction creates savory browned notes a slow cooker alone cannot produce. Transfer the pork to the slow cooker, pour the sauce over, and cook as directed. Verify doneness with an instant-read thermometer; pork is done at 145°F, and a 10-minute rest lets juices redistribute so every slice stays moist.
1. Classic Cranberry Pork Tenderloin
The original favorite. Brown sugar and orange juice round out the cranberries’ tartness without making the sauce candy-sweet.
- 1 cup fresh cranberries
- 1/2 cup brown sugar
- 1/2 cup orange juice

- Sear the seasoned tenderloins, 2 to 3 minutes per side.
- Whisk the cranberries, brown sugar, orange juice, and vinegar together and pour over the pork.
- Cook on LOW 3 to 4 hours or HIGH 2 to 2 1/2 hours, to 145°F.
- Rest the pork 10 minutes, tented loosely with foil, then slice into medallions.
- Simmer the sauce in a small saucepan over medium heat for 5 to 8 minutes until it coats a spoon, then spoon over the pork.
2. Orange Rosemary Cranberry Pork Tenderloin
Rosemary and orange zest give this version a fragrant, holiday-roast character — ideal for a dinner party.

- Cook on LOW 3 to 4 hours or HIGH 2 to 2 1/2 hours, to 145°F.
- Rest the pork 10 minutes before slicing; discard the rosemary sprigs.
- Reduce the sauce over medium heat for 5 to 8 minutes until glossy, then spoon over the pork.
3. Spicy Chipotle Cranberry Pork Tenderloin
Smoky chipotle peppers turn the sweet cranberry sauce bold and warming. The heat is gentle, and lime at the end keeps it bright.
- 1 cup fresh cranberries

- Rest the pork 10 minutes before slicing.
- Stir in the lime juice, simmer the sauce 5 minutes to thicken slightly, and spoon over the pork.
4. Balsamic Herb Cranberry Pork Tenderloin
This savory-leaning version trades sweetness for depth: balsamic, thyme, and Dijon make a sauce like a pan reduction.
- 1 cup fresh cranberries
- 1/3 cup balsamic vinegar
- 2 tablespoons maple syrup
- 1 tablespoon Dijon mustard
- 1 teaspoon fresh thyme leaves
- Sear the seasoned tenderloins, 2 to 3 minutes per side.

- Simmer the sauce 5 to 8 minutes until syrupy, then spoon over the pork.
5. Apple Cider Cranberry Pork Tenderloin
Apple cider and a diced apple make this the coziest version — fall orchard flavors that pair beautifully with sweet potatoes.
- 1 cup fresh cranberries
- 3/4 cup apple cider
- 1 apple, peeled and diced
- 2 tablespoons brown sugar
- 1/2 teaspoon ground cinnamon
- Sear the seasoned tenderloins, 2 to 3 minutes per side.
- Combine the cranberries, cider, apple, brown sugar, and cinnamon and pour over the pork.
- Cook on LOW 3 to 4 hours or HIGH 2 to 2 1/2 hours, to 145°F.

- Simmer the sauce 5 to 8 minutes until the apple is soft and the sauce coats a spoon, then spoon over the pork.
Tips for the Best Slow Cooker Cranberry Pork Tenderloin Every Time
Do not skip the sear: a slow cooker never gets hot enough to brown meat, and without it the pork tastes flat. Trim the silver skin first — that tough membrane never breaks down and makes the tenderloin curl and chew tough. Watch the clock, not just the setting: tenderloin is lean and small, so most slow cookers finish it in 3 to 4 hours on LOW, and 8 hours will dry it out regardless of sauce.
If your sauce looks thin, reduce it on the stovetop a few minutes: this concentrates flavor and thickens it naturally, since cranberries are rich in pectin. Always rest the meat — slicing immediately lets juices run onto the board instead of staying in the pork.
Easy Variations
Swap in boneless pork chops and reduce the LOW cook time to 2 1/2 to 3 hours. For a holiday version, double the sauce and serve sliced pork over stuffing. Frozen cranberries work like fresh ones — no thawing, just add 15 minutes. For a chunkier sauce, mash a few cranberries with a fork in the slow cooker.
Storage and Reheating
Store leftover pork and sauce together in an airtight container in the refrigerator for up to 4 days; keeping the meat in the sauce prevents drying out. Reheat gently in a covered skillet over low heat for 8 to 10 minutes, adding a splash of water or cider if the sauce thickened too much. Freeze sliced pork with sauce up to 3 months, thaw overnight in the refrigerator, and avoid microwaving on high, which turns tender pork rubbery fast.
Frequently Asked Questions
Can I use frozen cranberries?
Yes — no thawing needed. Add about 15 minutes to the cook time and reduce the sauce a little longer.
How do I know when pork tenderloin is done?
Use an instant-read thermometer in the thickest part. Pork tenderloin is done at 145°F, followed by a 10-minute rest. Slight pinkness in the center is safe and normal.
Can I cook this on HIGH if I am short on time?
Yes — 2 to 2 1/2 hours on HIGH works for all five. Check at the 2-hour mark, since slow cookers vary, and pull the pork at 145°F.
Why is my pork dry even though it cooked in sauce?
Usually overcooking: tenderloin dries out quickly past 150°F, so a thermometer matters more than the clock. Skipping the rest also costs moisture — give the pork its full 10 minutes.
Can I make this ahead for a party?
Absolutely. Cook fully the day before and refrigerate the pork in its sauce — flavors deepen overnight and the sauce thickens as it chills. Reheat gently in a covered skillet.
