Equipment: Must-haves

• Slow cooker (crock)
• Skillet (cast iron or heavy-bottomed)
• Sharp knife
• Cutting board
• Measuring spoons
• Measuring cup
• Wooden spoon
• Tongs
• Meat thermometer
• Serving platter

Equipment: Nice-to-haves

• Kitchen twine (for tying the tenderloin)
• Slow cooker liner (for easy cleanup)
• Immersion blender (to smooth the sauce)
• Fine mesh strainer (for glossy sauce finish)

Ingredients

• 1 pork tenderloin (about 1 to 1.25 lb)
• 1 tablespoon olive oil
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• 1 teaspoon ground cinnamon
• 1/4 teaspoon ground clove
• 1/2 teaspoon ground allspice
• 1 tablespoon brown sugar
• 1 small onion, thinly sliced
• 1 clove garlic, minced
• 1/2 cup red wine (a fruity red like Merlot)
• 1/2 cup cranberry sauce (or whole cranberry preserve)
• 1/4 cup orange juice
• 1 tablespoon balsamic vinegar
• 1 bay leaf
• 1 sprig thyme
• 1 tablespoon cornstarch
• 1 tablespoon cold water
• 1 tablespoon butter (optional, for finishing)
• 1 orange, zested (for brightness)
• 1 pinch flaky salt (to finish)

Instructions

1. Pat the pork dry on the cutting board and season it with salt and pepper.
2. Tie the tenderloin loosely with the kitchen twine so it keeps a nice shape while cooking.
3. Heat the skillet over medium-high and add the olive oil until it shimmers.
4. Sear the tenderloin on all sides until browned; use tongs to turn it like you mean it.
5. Transfer the seared tenderloin to the slow cooker and set it aside on the serving platter for a moment.
6. Add the sliced onion to the hot skillet and sauté until it softens and gets a little color.
7. Stir in the minced garlic and cook until fragrant for one quick moment.
8. Deglaze the skillet with the red wine, scraping up browned bits with the wooden spoon.
9. Stir in the cranberry sauce, orange juice, balsamic vinegar, brown sugar, cinnamon, clove, and allspice to the skillet to make the spiced wine cranberry base.
10. Bring the sauce to a gentle simmer so the flavors marry and the sugar dissolves.
11. Pour the warm sauce over the tenderloin in the slow cooker, then add the bay leaf and the sprig of thyme.
12. Cover and cook on low until the pork reaches the correct internal temperature and is tender.
13. Use the meat thermometer to check the thickest part of the tenderloin for doneness.
14. Remove the tenderloin from the slow cooker and let it rest briefly on the serving platter.
15. Whisk the cornstarch with cold water until smooth to make a slurry for thickening the sauce.
16. Skim any fat from the sauce in the slow cooker and spoon the sauce into the skillet or a bowl for thickening.
17. Stir the cornstarch slurry into the sauce over medium heat while whisking until it thickens to a glossy consistency.
18. For an extra-smooth sauce, use the immersion blender briefly in the skillet or pass the sauce through the fine mesh strainer.
19. Swirl the butter into the hot sauce for sheen and add orange zest for a bright lift.
20. Slice the tenderloin on the cutting board into medallions and arrange them on the serving platter.
21. Spoon the spiced wine cranberry sauce over the sliced pork and finish with a pinch of flaky salt.
22. Serve immediately while the sauce is warm and fragrant.

Good to Know

Tips: Use a slow cooker liner if you hate scrubbing; it’s like a crockery superhero cape. Doneness: The safe and juicy target is an internal temperature of 145°F followed by a short rest.

Searing is optional but recommended; it adds flavor and color that the slow cooker won’t give you. Sauce tricks: If the sauce is too tart, add a touch more brown sugar.

If it’s too thin, simmer with the cornstarch slurry until it thickens. Variations: Swap red wine for apple cider for a family-friendly version.

Serving: Pair with creamy mashed root vegetable or roasted sweet potato for a cozy plate. Make-ahead: You can prepare the sauce base ahead and freeze it; then thaw and finish in the slow cooker for an easy dinner rescue.

Leftovers: Slice cold leftover pork onto salads or tuck into sandwiches; the sauce makes everything feel fancy. Final note: That spiced wine cranberry aroma will make neighbors suspicious of your hosting skills.

Embrace it.
