- Small bowl and whisk (for sauce and slurry)
- Measuring spoons
- Ladle (for serving)
- Serving platter

Ingredients
- 1 pork tenderloin (about 1½ lb), trimmed
- 1 tablespoon olive oil
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 2 clove garlic, minced
- 1 small onion, thinly sliced
- 1 cup cranberry sauce (whole-berry or homemade)
- 1/2 cup low-sodium chicken broth
- 2 tablespoon brown sugar
- 1 tablespoon Dijon mustard
- 1 tablespoon balsamic vinegar
- 1/2 teaspoon dried thyme
- 1/4 teaspoon red pepper flakes (optional)
- 1 tablespoon cornstarch
- 2 tablespoon cold water
- 1 tablespoon fresh parsley, chopped (for garnish)

Instructions
- Pat the pork tenderloin dry and season all over with salt and pepper.
- Heat the skillet over medium-high heat and add the oil until shimmering.
- Sear the tenderloin on all sides until golden to lock in flavor and add texture.
- Place the seared tenderloin into the slow cooker and tuck any stray juices in the skillet into the crock for bonus flavor.
- In a bowl, whisk together the cranberry sauce, chicken broth, brown sugar, Dijon, balsamic, garlic, thyme, and red pepper flakes until smooth.
- Pour the cranberry mixture over the tenderloin in the slow cooker, coating it evenly.
- Cover and cook on low until the pork reaches the safe internal temperature and is tender.
- When the pork is nearly done, transfer the cooking liquid to a small saucepan or keep it in the slow cooker insert on high to reduce slightly.
- Make a cornstarch slurry by whisking the cornstarch into the cold water until smooth.
- Stir the slurry into the simmering cooking liquid and whisk until the sauce thickens and becomes glossy.
- Return the thickened sauce over the tenderloin or spoon it on when serving to keep the presentation tidy.
- Let the tenderloin rest briefly so the juices settle before slicing against the grain.
- Slice the tenderloin into medallion-thin pieces and arrange on a platter.
- Spoon extra cranberry glaze over the sliced pork and sprinkle with chopped parsley for color and freshness.

Good to Know
Tips: Searing is optional, but it adds a lovely caramelized flavor and keeps the tenderloin from turning into a mushy memory. Timing: Cook on low for a more forgiving finish and deeper flavor; cook on high if you’re short on time.
Internal Temp: Aim for an internal temperature of 145°F for safe, juicy pork—use a meat thermometer and don’t guess. Variations: Swap the brown sugar for maple syrup to lean into autumn vibes, or stir in a splash of orange juice for a bright twist.
Serving Suggestions: Pair with mashed potato, roasted root vegetable, or a simple green salad to balance the sweet glaze. Make-Ahead & Storage: Refrigerate sliced pork and sauce separately for up to three days; reheat gently in a skillet or low oven to preserve juiciness.
Thickening Trick: If your sauce gets too thick, loosen it with a splash of chicken broth. If it’s too thin, simmer it a bit longer or add a touch more slurry.
Final Thought: This recipe is comfort without the fuss—perfect for a cozy night in or when you want to impress without breaking a sweat. But here’s the catch!
Don’t skip the parsley unless you’re into monotone plating—garnish matters.
