The 4 Ingredients You’ll Need
Pork Tenderloin
Pork tenderloin is naturally lean and cooks quickly compared with larger pork cuts. Choose a tenderloin that fits comfortably in your slow cooker.
Apples
Apples bring sweetness and a wonderful fall flavor to the dish. Firm apples such as Honeycrisp, Gala, or Granny Smith work well because they hold their shape during cooking.
Whole-Berry Cranberry Sauce
Cranberry sauce adds sweetness, tartness, and plenty of seasonal flavor. Whole-berry cranberry sauce also provides a pleasant texture throughout the dish.
Dijon Mustard
Dijon mustard adds a little sharpness that balances the sweetness of the apples and cranberry sauce. It also gives the cooking juices a more savory flavor.
How to Make Slow Cooker Fall Harvest Pork Tenderloin
Step 1: Prepare the Pork
Pat the pork tenderloin dry with paper towels. Trim away any excess silver skin or visible fat if necessary.
Season lightly with salt and pepper if desired. These seasonings are optional and are not counted among the four main ingredients.
Step 2: Prepare the Apples
Wash and core the apples, then cut them into wedges or thick slices.
Avoid cutting the apples too thin, since thicker pieces are more likely to retain their shape during slow cooking.
Step 3: Layer the Ingredients
Place about half of the apple slices in the bottom of the slow cooker.
Place the pork tenderloin on top of the apples.
Spoon the cranberry sauce over the pork, then spread the Dijon mustard over the top.
Arrange the remaining apple slices around the pork.
Step 4: Slow Cook
Cover the slow cooker and cook on LOW for approximately 3 to 4 hours, or until the pork reaches an internal temperature of 145°F.
Cooking time can vary depending on the size and thickness of the tenderloin and the slow cooker being used.
Avoid overcooking the pork, since tenderloin is lean and can become dry if left in the slow cooker too long.
Step 5: Rest the Pork
Carefully transfer the cooked pork to a cutting board.
Let it rest for about 5 to 10 minutes before slicing. This gives the juices time to redistribute and helps keep the pork moist.
Step 6: Slice and Serve
Slice the pork into medallions and arrange them on a serving platter.
Spoon some of the warm apples and cranberry mixture over the top. Serve immediately with your favorite fall side dishes.
Tips for the Best Pork Tenderloin
Don’t Overcook the Pork
Pork tenderloin is lean, so keeping an eye on the internal temperature is important. Remove it when it reaches 145°F and allow it to rest.
Use Firm Apples
Firm apples hold up better during slow cooking. Softer varieties can become very tender and may partially break down into the sauce.
Don’t Add Too Much Liquid
The apples and cranberry sauce release moisture as they cook. There is usually no need to add a large amount of broth or water.
Let the Pork Rest
A short resting period after cooking makes a noticeable difference in texture. It allows the juices to settle before slicing.
Slice Against the Grain
For the most tender bite, look at the direction of the muscle fibers and slice across them rather than parallel to them.
Easy Variations
Add Warm Fall Spices
For additional seasonal flavor, add a small pinch of cinnamon, thyme, rosemary, or sage.
Use Different Apples
Try Granny Smith for extra tartness, Honeycrisp for a crisp sweet flavor, or Fuji for a sweeter result.
Add Pears
Replace some of the apples with firm pear slices for another delicious fall-inspired combination.
Add Onions
Sliced yellow or red onions can be added to the slow cooker for a more savory version.
Make It More Savory
Instead of emphasizing the sweetness, use a little extra Dijon mustard and add fresh herbs such as rosemary or thyme.

Make-Ahead Instructions
You can prepare the ingredients several hours before cooking.
Slice the apples and keep them refrigerated in an airtight container. Prepare the cranberry and Dijon mixture separately, then assemble everything in the slow cooker shortly before cooking.
For the best texture, cook the pork the same day you plan to serve it.
Storage
Allow leftover pork and apples to cool before transferring them to an airtight container.
Refrigerate for up to 3 to 4 days.
Reheat gently in the microwave or in a covered skillet over low heat. Add a spoonful of the cranberry-apple mixture when reheating to help keep the pork moist.
Can You Freeze Pork Tenderloin?
Yes. Allow the cooked pork to cool completely, then place it in an airtight freezer-safe container or freezer bag.
For the best quality, use within 2 to 3 months.
Thaw overnight in the refrigerator before reheating.
The apples may become softer after freezing and thawing, but the pork will still make a convenient leftover meal.
Frequently Asked Questions
Can I cook pork tenderloin on HIGH?
Yes, although LOW is preferred for this recipe because it provides gentle cooking. If using HIGH, begin checking the pork earlier to prevent overcooking.
Do I need to brown the pork first?
No. Browning can add extra flavor, but it is not necessary for this easy four-ingredient recipe.
Can I use pork loin instead?
You can, but pork loin is a different cut and is usually larger and thicker than pork tenderloin. Cooking times will vary, so use an instant-read thermometer to determine when it is done.
What temperature should pork tenderloin reach?
The USDA-recommended safe internal temperature for whole cuts of pork is 145°F, followed by a short rest.
Can I use fresh cranberries?
Fresh cranberries can be used, but they will produce a more tart result and may require additional sweetness. Whole-berry cranberry sauce keeps this recipe especially quick and convenient.
Can I make this recipe without apples?
Yes. You can replace the apples with pears, or simply increase the amount of cranberry sauce and serve the pork with your favorite fall side dishes.
