Equipment: Nice-to-haves
- Skillet (for searing and sauce)
- Meat thermometer
- Small bowl (for slurry)
- Silicone spatula
- Serving platter
Ingredients
- 1 pork tenderloin (about 1.25–1.5 lb), trimmed
- 1 small onion, thinly sliced
- 2 tablespoon butter, softened
- 1 cup cranberry sauce (jellied or whole-berry)
- 2 tablespoon brown sugar
- 1 tablespoon Dijon mustard
- 1 tablespoon balsamic vinegar
- 1/2 cup chicken broth
- 2 clove garlic, minced
- 1 teaspoon dried thyme
- 1 teaspoon cornstarch
- 1 tablespoon cold water
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1 tablespoon olive oil (optional for searing)
Instructions
- Pat the pork tenderloin dry and season it with salt and pepper.
- If using a skillet, heat oil over medium-high and quickly sear the pork on all sides until golden to lock in flavor; transfer the pork to the crock pot.
- On the cutting board, slice the onion and mince the garlic while your skillet is still warm.
- In the skillet, melt butter and sauté the onion until it softens and starts to caramelize, then add the garlic and stir until fragrant.
- Add the cranberry sauce, brown sugar, Dijon mustard, balsamic vinegar, chicken broth, and thyme to the skillet and stir with the wooden spoon to combine.
- Bring the sauce to a gentle simmer so flavors mingle; taste and adjust seasoning with salt and pepper if needed.
- If you want a thicker sauce, whisk the cornstarch with cold water in the small bowl to make a slurry, then stir the slurry into the skillet sauce until it thickens slightly.
- Pour the onion-cranberry sauce over the pork in the crock pot, spooning some sauce over the top so the meat gets cozy.
- Cover and cook on low until the pork reaches the right doneness, or cook on high if you’re short on time; use the meat thermometer to check for the safe internal temperature.
- Once the pork is cooked, remove it from the crock pot and let it rest a few minutes on the serving platter; tent it loosely with foil.
- Spoon the sauce from the crock pot into the skillet and reduce over medium heat if you want a more concentrated glaze for serving.
- Slice the pork against the grain using the sharp knife, arrange slices on the platter, and drizzle with the warm cranberry-onion sauce using the silicone spatula or wooden spoon.
- Serve with mashed root vegetable or grain of choice and garnish with extra thyme if feeling fancy.
Good to Know
Timing tip: Cook low for a gentle result that stays juicy, or cook high if you need dinner sooner. That’s why a meat thermometer is useful—aim for the safe internal temperature and then rest the meat so juices settle.
Searing shortcut: Searing is optional but recommended because it adds flavor and color. If you skip it, the recipe still works—no judgment.
But here’s the catch! Skipping the sear can make the sauce paler and the crust less snappy.
Thickening trick: If the sauce looks thin, use the cornstarch slurry and reduce briefly in a skillet to get a glossy glaze. You can also mash a bit of the sauce in the crock pot to thicken naturally.
Variation ideas: Swap dried thyme for fresh herb if you have it, or add a pinch of red pepper flake for heat. Try orange zest or a splash of orange juice for bright citrus notes.
Serving suggestion: This pork loves creamy mash or buttered grain and a simple green on the side. Leftovers keep well in the fridge for a couple of days and reheat beautifully—just add a splash of broth when warming to keep it juicy.
Food-safety note: Use the thermometer and rest the meat; slicing too soon steals the juices. Enjoy the cozy combo of butter, onion, and cranberry—it’s comfort with a little wow.
