There’s something about the combination of apple and cinnamon pork tenderloin that instantly feels like autumn — tender pork medallions slow-cooked alongside sweet potatoes and fresh apples, all dusted in warm cinnamon and simmered down into a glaze that’s sweet, savory, and deeply comforting all at once. This is the kind of dish that fills the house with the smell of a holiday dinner, even on an ordinary weeknight.
The slow cooker does the real work of marrying these flavors together. As the pork, sweet potatoes, and apples cook low and slow, the natural sugars in the apples and sweet potatoes caramelize gently, mingling with cinnamon and the pork’s own juices into a warm, cider-like glaze that coats everything in the pot. The tenderloin stays incredibly moist through the long cook, and the sweet potatoes turn soft and tender, soaking up all that cinnamon-apple flavor along the way.
This is the kind of dump-and-go dinner that feels like a genuine seasonal treat without demanding much from you at all. Load everything into the crockpot, let it simmer away for hours, and you’ll have a dinner that tastes like it belongs on a crisp fall evening, no matter what day of the week it actually is.

Ingredient Notes
Pork tenderloin, cut into thick medallions, is the ideal cut for this recipe since it’s naturally tender and takes on the sweet-savory flavors of the apples and cinnamon beautifully as it cooks. Be mindful not to overcook it, since tenderloin is leaner than other pork cuts and can dry out if left too long, even in the gentler environment of a slow cooker.
Sweet potatoes, sliced into rounds, bring natural sweetness and a hearty texture that holds up well through the cook time, while green apples (tart varieties like Granny Smith) provide a nice contrast to all that sweetness with their natural tartness. Using a tart apple variety rather than a sweeter one helps balance the dish, since the sweet potatoes and cinnamon already bring plenty of sweetness on their own.
A generous dusting of ground cinnamon, along with a splash of apple cider or apple juice, creates that warm, glaze-like sauce that coats everything in the slow cooker as it cooks. A touch of brown sugar or maple syrup stirred in enhances the natural sweetness further, while a pat of butter adds richness that ties the whole dish together into something that tastes truly indulgent despite its simple ingredient list.

Step-by-Step Instructions
- Season 1½ to 2 lbs pork tenderloin, cut into thick medallions, with salt, pepper, and ½ teaspoon cinnamon.Place the medallions in the bottom of your slow cooker. Tip: searing the pork briefly in a hot skillet before adding it to the slow cooker adds extra flavor, though this step can be skipped for a fully hands-off version.
- Peel and slice 2–3 medium sweet potatoes into rounds, about ½ inch thick, and arrange them around and on top of the pork.
- Core and slice 2 green apples into wedges and tuck them among the sweet potatoes and pork.
- Sprinkle everything generously with 1–1½ teaspoons ground cinnamon, along with a pinch of nutmeg if desired. Tip: dusting the cinnamon directly over the apples and sweet potatoes, as shown in the photo, helps it cling evenly rather than settling at the bottom of the pot.
- Pour ½ cup apple cider or apple juice over everything, along with 2 tablespoons melted butter and 1–2 tablespoons brown sugar or maple syrup. Tip: this liquid mixture is what creates that warm, glaze-like sauce, so don’t skip it even if you’re trying to keep things simple.
- Cover and cook on low for 4–5 hours, or on high for 2½–3 hours, until the pork reaches an internal temperature of 145°F and the sweet potatoes are fork-tender. Tip: check the pork’s temperature toward the earlier end of the time range, since tenderloin cooks faster than tougher cuts and can dry out if left too long.
- Once done, carefully remove the pork, sweet potatoes, and apples to a serving platter.
- If you’d like a thicker glaze, pour the remaining liquid into a small saucepan and simmer over medium heat for 5–10 minutes, until it reduces slightly. Tip: this step concentrates the flavor and gives you a glossier sauce to drizzle over the finished dish.
- Spoon the glaze over the pork, sweet potatoes, and apples before serving warm.

Storage & Reheating
Leftovers keep well in the refrigerator, covered, for up to 3–4 days. Reheat gently on the stovetop over medium-low heat or in the microwave in 1-minute intervals, being careful not to overcook the pork further during reheating. This dish also freezes reasonably well for up to 2 months, though the apples and sweet potatoes may soften slightly more after thawing.
Budget Note
This recipe costs roughly $2.75–$3.50 per serving, with pork tenderloin being the main expense. To save further, watch for sales on pork tenderloin, which is often discounted, and use in-season apples and sweet potatoes, both of which are typically more affordable in the fall.
Variations to Try
Healthy/Lighter Version: Reduce the brown sugar or maple syrup slightly and use a light drizzle of butter instead of a full pat to cut back on added sugar and fat. The natural sweetness of the apples and sweet potatoes still carries plenty of flavor even with less added sweetener.
Instant Pot / Pressure Cooker Method: Combine all the same ingredients in the Instant Pot and pressure cook on high for 8–10 minutes with a quick release, checking the pork’s internal temperature to ensure it’s fully cooked. Reduce the sauce using the sauté function afterward if you’d like a thicker glaze.
Meal-Prep Friendly: This dish reheats reasonably well, making it a good option to portion into containers for a few days’ worth of lunches or dinners. The flavors meld together nicely, so leftovers often taste just as good as the first serving.
Savory Twist: Reduce the cinnamon and sweetener slightly, and add fresh rosemary or thyme along with a splash of chicken broth instead of apple cider for a more savory-leaning version. This variation still keeps the apple and sweet potato pairing but shifts the overall flavor profile to be less dessert-like.
Frequently Asked Questions
Can I make this ahead of time? Yes, this dish reheats reasonably well, making it a good option to prepare a day in advance. Reheat gently to avoid overcooking the pork further, since it’s already a leaner cut that can dry out if reheated too aggressively.
What can I use instead of green apples? Honeycrisp or Gala apples can work if you prefer a sweeter apple, though the dish will lean even more toward dessert-like sweetness. Granny Smith or another tart variety is recommended to help balance out the overall sweetness of the dish.
Why is my pork dry instead of tender? This usually means the tenderloin cooked too long, since it’s a leaner cut that doesn’t have as much forgiving fat as something like a pork shoulder. Check the internal temperature toward the earlier end of the recommended cook time and remove it as soon as it reaches 145°F.
Can I use a different cut of pork? Pork loin or boneless pork chops can work as substitutes, though cooking times may vary slightly depending on thickness. Avoid cuts that are too lean and thin, since they’re even more prone to drying out over a long cook time.
What should I serve with apple cinnamon pork tenderloin? This dish is fairly complete on its own with the sweet potatoes included, though a simple green salad or steamed green vegetable helps balance out the sweetness. Crusty bread is also nice for soaking up any extra glaze.
