There are some dinners that feel like autumn on a plate, and this 4-Ingredient Slow Cooker Fall Harvest Pork Tenderloin is absolutely one of them. It is a tender, juicy pork tenderloin bathed in a sweet and savory sauce that captures everything we love about the season—warm spices, a touch of sweetness, and that deep, comforting flavor that makes you want to curl up by the fire.

What I love most about this recipe is how effortlessly it comes together. With just four simple ingredients and a few hours in the slow cooker, you can create a meal that tastes like you spent all day in the kitchen.

Ingredients

2 pounds pork tenderloin (or pork loin)
1 can (14 ounces) whole berry cranberry sauce
1 packet (1 ounce) dry onion soup mix
½ cup apple cider or apple juice

Salt and pepper are considered free pantry staples and can be added to taste.

Directions

Prep the slow cooker: Lightly grease the inside of a 4- to 6-quart slow cooker with nonstick spray or a little butter.
Season the pork: Pat the pork tenderloin dry with paper towels and season all over with salt and pepper.
Place in slow cooker: Place the pork tenderloin in the bottom of the slow cooker.
Mix the sauce: In a medium bowl, whisk together the cranberry sauce, dry onion soup mix, and apple cider until well combined.
Pour over pork: Pour the sauce mixture evenly over the pork tenderloin.
Cook: Cover and cook on LOW for 6 to 8 hours, or on HIGH for 3 to 4 hours, until the pork is very tender and easily shreds with a fork.
Rest and serve: Remove the pork from the slow cooker and let it rest for 5-10 minutes before slicing or shredding. Return the pork to the sauce and stir to coat. Serve hot.

Variations

Cranberry Apple Pork: Add 1 sliced apple to the slow cooker along with the pork for extra sweetness and texture.
Spicy Harvest Pork: Add a pinch of red pepper flakes or a diced jalapeño to the sauce for a little heat.
BBQ Harvest Pork: Stir in ½ cup of your favorite barbecue sauce along with the cranberry sauce for a smoky, tangy twist.
Herb Infusion: Add 1 teaspoon of dried thyme or rosemary to the sauce for an earthy, aromatic note.
Pork Chops Version: Use 4 thick-cut boneless pork chops instead of tenderloin and reduce the cooking time to 4-5 hours on LOW.
Slow Cooker Harvest Chicken:Swap the pork for 2 pounds of boneless, skinless chicken thighs and cook for 5-6 hours on LOW.

Expert Tips

Use pork tenderloin or pork loin:Tenderloin is lean and cooks quickly, while pork loin is slightly larger and equally delicious. Both work beautifully.
Don’t lift the lid: Resist the urge to peek during cooking. Every time you lift the lid, you release heat and extend the cooking time.
Sear for extra flavor: For a deeper flavor, sear the pork in a hot skillet with a little oil before placing it in the slow cooker. This step is optional but highly recommended.
Shred or slice: This pork is tender enough to shred, but it also slices beautifully. Let it rest before slicing for the juiciest results.
Adjust sweetness: If the cranberry sauce is too sweet for your taste, add a splash of apple cider vinegar or lemon juice to balance it.

Storage and Reheating

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat gently on the stovetop or in the microwave with a splash of broth or water to loosen the sauce. This dish freezes beautifully for up to 3 months—thaw overnight in the refrigerator before reheating.

Frequently Asked Questions

Can I use jellied cranberry sauce instead of whole berry? Yes. Jellied cranberry sauce works just as well and creates a smoother sauce.
Can I use a different cut of pork?Pork shoulder or pork butt also work well and become very tender, though they require a longer cooking time.
Can I make this in the oven? Yes. Place everything in a Dutch oven, cover, and bake at 325°F for 2-3 hours, until the pork is tender.
What if I don’t have apple cider?Apple juice, white grape juice, or even chicken broth works well as a substitute.
Can I add vegetables? Yes. Carrots, potatoes, or parsnips can be added to the slow cooker with the pork for a complete one-pot meal.

What to Serve With This Dish

Creamy mashed potatoes or buttered egg noodles.
Steamed green beans, roasted carrots, or a crisp green salad.
