Ingredients
- 1 pork loin (about 2.5 lb), trimmed
- 1 tablespoon olive oil
- 1 small onion, thinly sliced
- 3 clove garlic, minced
- 1 can diced tomato (14 oz)
- 2 tablespoon tomato paste
- 1 cup low-sodium chicken broth
- 1 tablespoon Worcestershire sauce
- 1 tablespoon brown sugar
- 1 tablespoon apple cider vinegar
- 4 sprig fresh thyme
- 1 bay leaf
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 2 tablespoon cornstarch (for slurry)
- 2 tablespoon cold water (for slurry)
- 1 tablespoon butter (optional, to finish)
- 1 sprig fresh thyme (for garnish, optional)
Instructions
- Pat the pork loin dry and season the surface with salt and pepper.
- Heat the skillet over medium-high heat and add the olive oil.
- Sear the pork loin on all sides until browned for extra flavor and color.
- Transfer the seared pork loin to the crock pot using tongs.
- Add the sliced onion and minced garlic to the skillet and sauté briefly to soften and wake up the aromatics.
- Deglaze the skillet with a splash of chicken broth, scraping up browned bits, and pour that into the crock pot.
- Add the can of diced tomato, tomato paste, remaining chicken broth, Worcestershire sauce, brown sugar, apple cider vinegar, thyme sprig, and bay leaf to the crock pot.
- Nestle the pork loin into the tomato mixture so it sits mostly covered by the sauce.
- Cover and cook on low until the pork loin is tender and an inserted meat thermometer reads safe temperature, or cook on high for a faster finish.
- Use a meat thermometer to check doneness and remove the pork loin when it reaches a safe internal temperature and is tender to the touch.
- Transfer the pork loin to a cutting board and tent loosely with foil to rest while you thicken the sauce.
- Stir together the cornstarch and cold water in the small bowl to make a slurry.
- Ladle the cooking liquid into the skillet and bring it to a simmer, whisking in the slurry until the sauce thickens.
- Swirl in the butter to finish the sauce for a glossy mouthfeel and adjust seasoning with a pinch of salt and pepper if needed.
- Slice the rested pork loin against the grain and arrange on a serving platter.
- Spoon the thickened tomato thyme sauce over the sliced pork and garnish with a fresh thyme sprig.
- Serve with mashed potato, roasted vegetable, or crusty bread to mop up the sauce.
- Store leftovers in an airtight container in the fridge and reheat gently to avoid drying the meat.
Good to Know
Tips: Searing is optional, but it adds flavor and prettier color—don’t skip if you can. If you forget to sear, the slow cooker still saves the day.
For a quicker weeknight option, cook on high until the pork is tender—just watch the clock. Variations: Swap the fresh thyme for dried thyme if needed; use one teaspoon and add it earlier.
A splash of balsamic vinegar in place of apple cider vinegar gives a deeper sweetness. Low-carb option: Serve the pork over mashed cauliflower or a bed of sautéed greens.
Thickening note: The cornstarch slurry gives a glossy sauce; if you prefer a rustic finish, mash a few beans or soften the onion longer to naturally thicken. Serving suggestion: Slice the pork thin so each bite soaks in more tomato thyme goodness.
Leftovers and storage: Keep in the fridge for up to four days or freeze slices and sauce for up to three months. Reheat gently in a skillet with a splash of broth or in the oven covered at low heat to keep the pork juicy.
Timeline: Prep takes about 15 minutes, sear and deglaze add another 10, and slow cooking is the rest—plan your day accordingly. That’s why this recipe is perfect for busy nights or lazy weekends—minimal effort, maximum comfort.
Chef’s wink: Add a pinch of red pepper flakes if you like a sly little heat—because grown-up dinners deserve surprises too.
