Slow Cooker Cranberry Pork Tenderloin

Introduction

There’s something quietly magical about combining the tart brightness of cranberries with succulent, slow-cooked pork tenderloin. This recipe is cozy and festive, yet entirely comforting—perfect for a relaxed weeknight dinner, or even a weekend gathering when you want something a little special without a lot of fuss. As the pork simmers gently in the slow cooker, the cranberries soften and burst, releasing their tangy juices, which mingle with sweet brown sugar, savory herbs, and a touch of citrus to form a deeply flavorful sauce.

When you lift the lid, you’re greeted by a warm, ruby-hued glaze and the fragrance of simmering fruit and meat melding in harmony. The pork itself becomes tender and juicy, infused with a gentle sweetness and subtle acidity. Each bite is a beautiful balance: the lean, delicate texture of tenderloin softened by the rich, fruity sauce. Serving this feels like giving your dinner table a festive hug.

This recipe is also wonderfully forgiving. With minimal hands-on time, you can set it and forget it, letting the slow cooker do all the work. And because the sauce is luscious and vibrant, it doubles beautifully as a finishing glaze or even a leftover sauce to drizzle over roasted vegetables or grain bowls.

Ingredients

• 2 lb (≈ 900 g) pork tenderloin, trimmed
• 1 tablespoon olive oil (or neutral oil)
• Salt and freshly ground black pepper, to taste
• 1 small yellow onion, finely chopped
• 3 cloves garlic, minced
• 2 cups fresh or frozen cranberries (about 240 g)
• ½ cup brown sugar, packed
• ¼ cup apple cider (or apple juice)
• ¼ cup orange juice (freshly squeezed is great)
• 2 tablespoons balsamic vinegar
• 1 teaspoon dried thyme, or 1 tablespoon fresh thyme leaves
• Zest of 1 orange (optional, for brightness)
• ½ cup low-sodium chicken broth (or water)
• 2 tablespoons cornstarch (for thickening, if needed)
• 2 tablespoons cold water (for the cornstarch slurry)

Optional garnish:

• Fresh parsley or thyme sprigs
• Orange slices or cranberry-sugar rim (for presentation)

Instructions

1. Prepare the pork
   • Pat the pork tenderloin dry with paper towels, then season generously all over with salt and pepper.
   • In a large skillet over medium-high heat, warm the olive oil.
   • Sear the tenderloin on all sides — about 2–3 minutes per side — until it develops a golden-brown crust. This step helps lock in flavor and juices.
2. Build the sauce in the slow cooker
   • Place the chopped onion and minced garlic in the bottom of the slow cooker.
   • Add the cranberries, brown sugar, apple cider, orange juice, balsamic vinegar, thyme, and orange zest (if using).
   • Pour in the chicken broth or water, and stir gently to combine.
3. Add the pork and cook
   • Nestle the seared pork tenderloin into the cranberry mixture in the slow cooker.
   • Cover and cook on Low for 6–7 hours, or on High for 3–4 hours, until the pork is tender and cooked through (internal temperature about 145°F / 63°C, but it may rest further).
4. Finish the sauce
   • Once the pork is cooked, carefully remove it from the slow cooker and set it aside on a cutting board; let it rest for 10–15 minutes.
   • Meanwhile, turn the slow cooker to High (if not already), and taste the cooking liquid.
   • If the sauce feels loose, combine the cornstarch and cold water to make a slurry, then stir into the liquid. Let the sauce thicken for 5–10 minutes, stirring occasionally.
   • Adjust the seasoning with additional salt, pepper, or a touch more brown sugar or vinegar, depending on your taste.
5. Serve
   • Slice the rested pork tenderloin into medallions and arrange on a serving platter.
   • Spoon the thickened cranberry sauce over the top.
   • Garnish with fresh parsley or thyme and a few orange slices, if desired.

You Must Know (Helpful Tips)

• Trim the tenderloin: Removing excess fat and silver skin ensures even cooking and better texture.
• Don’t rush the sear: Take your time to get a nice crust; it adds flavor and locks in moisture.
• Balance your sweetness: Taste the sauce as it cooks — cranberries are tart, so you may want more or less sugar depending on your batch.
• Thickening matters: Use the cornstarch slurry only if the sauce is very loose; over-thickening can make it gloopy.
• Rest the pork: Letting the tenderloin rest after cooking helps the juices redistribute and keeps it juicy when you slice.
• Stir gently: When thickening, stir slowly so you don’t break down the whole cranberries too aggressively.

Storage Tips

• Refrigerate: Place leftover pork and sauce in an airtight container. Keep in the fridge for up to 4 days.
• Freeze: Store in a freezer-safe container or bag for up to 3 months.
• Reheat: Thaw overnight in the fridge. Reheat on the stove over low heat, stirring often. If the sauce has thickened too much, add a splash of water or broth to adjust.

Ingredient Substitutions

• Fruit: If you don’t have cranberries, you can use tart cherries, pomegranate seeds, or a mix of berry fruit.
• Juice: Swap apple cider with pear juice or white grape juice if needed.
• Vinegar: Use red wine vinegar or apple cider vinegar in place of balsamic, though the flavor will be a little sharper.
• Herbs: Rosemary, sage, or a pinch of ground allspice can also complement the pork and fruit.
• Sweetener: Use maple syrup or honey instead of brown sugar, but reduce the amount slightly for balance.

Serving Suggestions

• Serve the pork medallions with creamy mashed potatoes, buttery egg noodles, or fluffy rice to soak up the sauce.
• Pair with roasted Brussels sprouts, sautéed green beans, or a crisp salad (like arugula with citrus vinaigrette) to contrast the sweetness.
• Offer crusty bread or a warm baguette on the side to let guests mop up every drop of the cranberry glaze.
• For a brunch twist, serve leftover tenderloin slices on toasted English muffins or croissants, topped with sauce and a sprinkle of fresh herbs.

Pro Tips

• For extra depth, marinate the pork in half of the cranberry mixture in the fridge for a few hours or overnight before slow cooking.
• Try using a slow cooker liner for easier cleanup — this sauce can get sticky.
• If you prefer a smoother sauce, blend part or all of the cranberry mixture with an immersion blender before thickening.
• Add a splash of red wine to the sauce in place of some of the broth for a richer flavor profile.
• Brighten up the final presentation by stirring in a teaspoon of orange or lemon zest just before serving.

Frequently Asked Questions (FAQ)

Q: Can I use pork loin instead of tenderloin?
A: Yes — pork loin works, though it’s a bit leaner and may need slightly more cooking time. Be careful not to overcook, and rest it well to retain moisture.

Q: My sauce is too tart / too sweet — how can I fix it?
A: Taste the sauce after cooking. If it’s too tart, slowly add more brown sugar (or a little honey) until balanced. If it’s too sweet, stir in a small extra splash of balsamic vinegar or a dash of apple cider vinegar to sharpen it up.

Q: Do I have to thicken the sauce with cornstarch?
A: Not necessarily — if you like a thinner, runnier glaze, you can skip the slurry. But if you want a rich, clingy sauce for serving over slices, thickening helps it coat beautifully.

Q: Is this recipe good for entertaining?
A: Absolutely. You can make it ahead of time, reheat gently, and serve family-style on a platter. The sauce is elegant and festive, making it great for guests.

Q: Can I make this in an Instant Pot or stovetop?
A: Yes, you can adapt it. On the stovetop, brown the pork and then simmer the fruit mixture gently until the pork is cooked (about 20–30 minutes). In an Instant Pot, sear using “Sauté,” then pressure cook on High for 10 minutes, allow a natural release, then thicken the sauce after removing the pork.

Q: Will the cranberries stain the meat or hands?
A: Cranberry juice can leave a slight stain, but rinsing and patting dry before searing helps. When handling, use gloves if it bothers you, and wash cutting boards promptly.
