- Fine mesh strainer
Ingredients
- 1 pork tenderloin (about 1 to 1.5 lb), trimmed
- 1 tablespoon olive oil
- 1 small onion, thinly sliced
- 2 clove garlic, minced
- 1 cup whole berry cranberry sauce (store-bought or homemade)
- 1/2 cup orange juice
- 2 tablespoon brown sugar
- 1 tablespoon Dijon mustard
- 1 teaspoon fresh rosemary, chopped (or 1/2 teaspoon dried)
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1 tablespoon cornstarch
- 2 tablespoon cold water
- 1 sprig fresh thyme for garnish (optional)
Instructions
- Pat the pork tenderloin dry on the cutting board and trim any shiny bits so it looks tidy and not like a science experiment.
- Season the tenderloin with salt and pepper on all sides and set it aside on the cutting board.
- Heat the skillet over medium-high and add the olive oil until it shimmers like it’s excited.
- Sear the pork on each side until browned so you get a flavor boost; use tongs to turn it like a pro. That step is optional but worth the tiny effort.
- Move the seared pork to the slow cooker and place it on top of a bed of sliced onion and garlic.
- In the mixing bowl whisk together the cranberry sauce, orange juice, brown sugar, Dijon mustard, and chopped rosemary until glossy and slightly smooth.
- Pour the cranberry mixture over the tenderloin so it’s cozy and saucy in the slow cooker.
- Cover and cook on low for several hours or on high for a shorter time until the pork reaches a safe internal temperature. That’s why a meat thermometer is handy.
- When the pork is nearly done, remove it from the slow cooker and transfer to the cutting board to rest so the juices stay put instead of running away.
- Pour the sauce from the slow cooker into the skillet and bring it to a gentle simmer to concentrate the flavors.
- Mix the cornstarch with cold water in a small bowl to make a slurry and whisk it into the simmering sauce to thicken it to a glossy finish.
- Taste the sauce and adjust seasoning if needed. Add a pinch more salt or a splash of orange juice if it needs brightness.
- Slice the rested pork against the grain into medallions and arrange them on the serving platter with the onion tucked around them.
- Spoon the thickened cranberry sauce over the pork so every slice gets some sticky goodness.
- Garnish with the thyme sprig and a little extra rosemary if you’re feeling fancy.
- Serve immediately with your favorite side so you can bask in applause and excuses like, ‘I totally planned this.’
Good to Know
Cooking time: Cook on low for about 4 to 6 hours or on high for about 2 to 3 hours depending on your slow cooker and tenderloin size. Internal temperature: Aim for 145°F for juicy pork, then let the meat rest for a few minutes.
A meat thermometer takes the guesswork out of this and saves you from dry pork sorrow. Searing is optional but recommended.
Searing adds brown flavor and a better-looking crust. If you’re in a hurry, skip it and own your life choices.
Thickening: The cornstarch slurry gives the sauce a glossy coat. Add it slowly and simmer until you hit the right sheen.
If you prefer no-thicken, serve the sauce as-is for a looser glaze. Variations: Swap brown sugar for maple syrup for a rustic twist.
Stir in a splash of balsamic vinegar for depth. Add chopped apple or pear for a sweet-tart texture that plays well with cranberry.
Serving suggestion: This tenderloin loves mashed potato, buttered egg noodle, or wild rice. A simple green vegetable or roasted Brussels sprout makes dinner feel balanced and not like you only ate fruit and meat.
Leftovers: Slice cold and make a warm sandwich the next day with mustard and leftover sauce, or chop into salad for a grown-up lunch. Store in an airtight container in the fridge for up to three days.
Make-ahead: You can prepare the sauce in advance and refrigerate. Just pour it into the slow cooker when you start cooking.
Less morning drama. Final tip: Slow cooker meals are about layering flavor, not complexity.
Trust the process, wear an apron if you want, and get ready to enjoy a single pork tenderloin that somehow feeds more than your ego.
