Contents
Equipment: Must-haves
- Slow cooker (crock pot)
- Sharp knife
- Cutting board
- Mixing bowl
- Measuring spoons
- Wooden spoon or silicone spatula
- Tongs

Equipment: Nice-to-haves
- Cast-iron skillet (for optional searing)
- Meat thermometer (for perfect doneness)
- Small saucepan (for thickening sauce if you skip searing)

Ingredients
- 1 pork tenderloin (about 1 to 1.25 lb), trimmed of silver skin
- 1 cup cranberry (fresh or frozen)
- 1/2 cup whole-berry cranberry sauce (store-bought or homemade)
- 1/2 cup apple cider or apple juice
- 2 tablespoon brown sugar
- 1 tablespoon Dijon mustard
- 1 small onion, thinly sliced
- 1 apple, peeled and diced (sweet-tart variety recommended)
- 2 clove garlic, minced
- 1 sprig fresh rosemary (or 1/2 teaspoon dried rosemary)
- 1 bay leaf
- 1 tablespoon Worcestershire sauce (or soy sauce for a lighter salt note)
- 1 teaspoon smoked paprika
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1 tablespoon cornstarch (for slurry)
- 2 tablespoon cold water (for slurry)
- 1 tablespoon olive oil (optional, for searing)

Instructions
- Pat the pork tenderloin dry and trim any visible silver skin on a cutting board with a sharp knife.
- Season the pork all over with the smoked paprika, salt, and black pepper and set it aside.
- In a mixing bowl, combine the cranberry, whole-berry cranberry sauce, apple cider, brown sugar, Dijon mustard, Worcestershire sauce, minced garlic, and stir with a spoon until smooth.
- Toss the sliced onion and diced apple into the slow cooker and nestle the bay leaf and rosemary on top of them.
- Place the seasoned pork tenderloin on top of the onion and apple bed in the slow cooker.
- Pour the cranberry mixture evenly over the pork so it gets a generous glaze while it cooks.
- If you want deeper flavor and crisper edges, heat a cast-iron skillet with olive oil and sear the pork briefly on all sides before placing it in the slow cooker (optional).
- Cover and cook on low until the pork reaches the proper internal temperature, or on high if you’re short on time.
- Use tongs to lift the pork out of the slow cooker and let it rest on a cutting board while you finish the sauce.
- Remove and discard the bay leaf and rosemary stem from the slow cooker liquid.
- Skim off excess fat if needed, then transfer some of the cooking liquid to a small bowl and whisk the cold water into the cornstarch to make a slurry.
- Pour the slurry into the slow cooker liquid and whisk, then simmer in a small saucepan or on the warm setting of the slow cooker until the sauce thickens and becomes glossy.
- Slice the pork tenderloin against the grain into medallions and spoon the thickened cranberry sauce over the slices before serving.
- Serve immediately with your favorite sides and garnish with a small sprig of rosemary if you’re feeling fancy.

Good to Know
Tip: Use a meat thermometer to check for doneness; the safe and juicy internal temperature for pork is 145°F. That’s why resting the meat matters — it keeps juices where you want them.
But here’s the catch! If you skip searing, you still get great flavor; searing just adds a caramelized crust and faster-looking results.
Variation: Swap the apple cider for pear nectar or orange juice to change the sweet-acid balance and experiment with a hint of citrus brightness. Serving suggestion: Pair the sliced pork with mashed potato, roasted root vegetable, or buttered egg noodles to soak up the cranberry sauce like a true culinary sponge.
Sauce hack: If the sauce is too tart, stir in a pinch more brown sugar or a dab of honey until it sings. If it’s too sweet, a splash of apple cider vinegar will balance it right away.
Make-ahead note: You can prepare the cranberry mixture and aromatics the night before; refrigerate them separately and pop everything into the slow cooker when you’re ready. Leftovers: Slice the chilled pork thin for sandwiches with a smear of sauce and arugula — adult lunchbox level unlocked.
Final thought: This recipe is cozy, forgiving, and a little bit showy — which means you get comfort food without the drama. Enjoy every saucy bite.
