Ingredients
- 1 pork tenderloin (about 1 to 1.5 lb)
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 tablespoon olive oil
- 1 small onion, thinly sliced
- 2 cloves garlic, minced
- 1/2 cup cranberry sauce (jellied or whole-berry both work)
- 1/2 cup chicken broth
- 1 tablespoon balsamic vinegar
- 1 tablespoon brown sugar
- 1 teaspoon Dijon mustard
- 1 teaspoon fresh thyme leaves (or 1/4 teaspoon dried thyme)
- 1 teaspoon orange zest (optional but excellent)
- 1 tablespoon cornstarch
- 2 tablespoons cold water
- 1 tablespoon butter (for finishing)
- Fresh parsley for garnish (optional)
- Tip: Use a single pork tenderloin so everyone knows exactly what they’re fighting over.

Instructions
- Pat the pork tenderloin dry and season it all over with salt and pepper.
- Heat the skillet over medium-high and add the olive oil until it shimmers.
- Sear the pork on all sides until it develops a golden crust to lock in flavor.
- Transfer the seared pork to the slow cooker and arrange the sliced onion and minced garlic around it.
- In the mixing bowl, whisk together cranberry sauce, chicken broth, balsamic vinegar, brown sugar, Dijon, thyme, and orange zest until smooth.
- Pour the cranberry glaze over the pork and onions so everything gets a cozy nap.
- Cover and cook on low or high depending on your schedule; check with a meat thermometer toward the end of the cook time.
- But here’s the catch! Don’t overcook—remove the pork when the thermometer reads the safe internal temperature and the meat feels tender.
- Transfer the pork to the cutting board and tent it loosely with foil to rest while you finish the sauce.
- Ladle the cooking liquid into the skillet and bring it to a gentle simmer to concentrate the flavors.
- Mix the cornstarch with cold water to form a slurry and whisk it into the simmering sauce to thicken.
- Stir in the butter for shine and taste; adjust seasoning with salt and pepper as needed.
- Slice the rested pork into medallions and arrange them on the serving platter.
- Spoon the glossy cranberry sauce over the pork and garnish with parsley.
- Serve with mashed potato, roasted vegetable, or a bed of rice to soak up every last drop.

Good to Know
Temperature tip: The safe internal temperature for pork is measured with a meat thermometer and should reach the recommended reading; rest the meat so juices redistribute. If you want deeper flavor, sear the pork well before slow cooking—this step is optional but highly recommended for texture and taste.
To make the sauce ahead, refrigerate the slow cooker juices separately and thicken on the stovetop when ready to serve. For a lighter version, swap brown sugar for a drizzle of maple syrup and cut back on added butter.
Leftovers keep well in the fridge for a few days and make excellent sandwiches or salad toppers. Serving suggestion: Pair with mashed potato or wild rice and a simple green for balance and a dinner that feels plated-by-someone-who-plans.
Variation idea: Add a sprig of rosemary to the slow cooker for an herbaceous twist, or stir in a splash of orange juice for extra brightness. Final trick: If your sauce is too thin, simmer it uncovered a few minutes longer; if it’s too thick, loosen with a little broth.
This recipe gives you juicy, tender pork with bright cranberry notes and minimal fuss—perfect for a weeknight win or a small celebration without sweating the details.
