Ovenbaked Southern Pork Loin

A bone-in pork loin roast gets basted repeatedly with a tangy-sweet sauce made from sauteed onions, celery, tomato puree, apple cider vinegar, and molasses. Each brushing builds up another layer of sticky, caramelized glaze on the outside while the meat stays juicy inside.

The sauce comes together in minutes: soften onions and celery in butter, then stir in the tomato puree, vinegar, and molasses. That combination hits the sweet-sour-smoky notes that define Southern barbecue flavor without needing a grill or a smoker.

Brushing the pork with sauce every 20 minutes or so during the roast is what builds that lacquered finish. The sugars in the molasses caramelize in the oven heat and create a dark, glossy bark.

Pro Tips

• Use a roasting rack so the heat circulates under the meat. Sitting in its own juices will braise the bottom instead of roasting it.
• Check for doneness by piercing the thickest part. The juices should run clear with no pink.
• Let the roast rest for 10 minutes before slicing so the juices redistribute through the meat.
• Bone-in gives better flavor and helps the roast stay moist. Don’t substitute boneless here.

Variations

• Add a tablespoon of Dijon mustard to the sauce for a sharper, more complex glaze.
• Stir a pinch of cayenne or hot sauce into the basting mixture for some heat.
• Use this same sauce on bone-in pork chops and reduce the baking time to about 35 minutes.
