Instructions
Step 1: Prepare the Marinade
In a large bowl or baking dish, combine the Coca-Cola, soy sauce, brown sugar, Dijon mustard, oil, Worcestershire sauce, ketchup, garlic, dry mustard, balsamic vinegar, ginger, and thyme.
Whisk until the brown sugar is mostly dissolved and everything is well combined.
Step 2: Marinate the Pork
Place the pork loin in a large resealable bag or deep baking dish.
Pour the marinade over the pork, making sure it is well coated.
Cover and refrigerate for at least 8 hours, preferably overnight.
Turn the pork occasionally so the marinade reaches all sides.
Step 3: Prepare the Oven
Preheat your oven to 325°F (165°C).
Remove the pork from the marinade and discard the used marinade.
Pat the outside of the pork gently with paper towels.
Place the roast fat-side up on a rack inside a roasting pan.
Step 4: Roast the Pork
Roast uncovered for approximately 30–40 minutes per pound, depending on the size and shape of the roast.
For a traditional 5-pound roast, this can take roughly 2½–3 hours.
Use a meat thermometer to determine doneness rather than relying solely on cooking time.
Food-safety note: For modern pork cooking, whole pork roasts can be served at 145°F (63°C) followed by a 3-minute rest. If you prefer the older, more well-done style of this particular recipe, the pork can be cooked longer.
Step 5: Make the Glaze
While the pork is roasting, combine the brown sugar, Coca-Cola, balsamic vinegar, cornstarch, butter, dry mustard, salt, and pepper in a saucepan.
Place over medium heat.
Bring the mixture to a gentle boil, then reduce the heat and simmer for approximately 10–15 minutes, stirring frequently, until the glaze thickens.
Step 6: Glaze the Pork
During the final 30 minutes of roasting, brush the Coca-Cola glaze generously over the pork.
Continue glazing several times as it cooks.
The sugar in the glaze will create a glossy, caramelized exterior.
Watch carefully near the end so the glaze doesn’t burn.
Step 7: Rest the Pork
Remove the pork from the oven and transfer it to a cutting board or serving platter.
Tent loosely with foil and let it rest for approximately 10–15 minutes before slicing.
Resting allows the juices to redistribute throughout the meat.
Step 8: Slice and Serve
Slice the pork into thin or medium-thick pieces.
Drizzle with additional Coca-Cola glaze and serve immediately.
Tips for the Best Coca-Cola Pork Loin
Marinate overnight
The longer marinade allows the sweet, savory, and tangy flavors to penetrate the pork.
Use regular Coca-Cola
Traditional versions use regular Coca-Cola because its sugar contributes to the caramelized flavor and glaze.
Don’t skip the glaze
The glaze is what gives the finished pork its distinctive sweet, glossy exterior.
Use a meat thermometer
Pork loin is lean, so a thermometer is the easiest way to avoid overcooking.
Let it rest
Cutting immediately after roasting can cause the juices to run out. Give the roast time to rest before slicing.
Delicious Variations
Spicy Coca-Cola Pork
Add cayenne pepper, crushed red pepper flakes, or hot sauce to the marinade.
Garlic Herb Pork
Increase the garlic and add fresh rosemary or sage.
Orange Coca-Cola Pork
Add a little orange zest and fresh orange juice to the glaze for a bright citrus flavor.
Smoky Southern Pork
Add smoked paprika to the marinade and glaze.
Slow-Roasted Pork
For a slower preparation, roast at a lower temperature for a longer period. Some versions recommend 250–275°F (120–135°C) for a more tender result.
What to Serve With It
This pork loin pairs beautifully with:
- Creamy mashed potatoes
- Roasted potatoes
- Sweet potatoes
- Green beans
- Glazed carrots
- Corn on the cob
- Southern-style coleslaw
- Macaroni and cheese
- Roasted vegetables
- Dinner rolls
For a classic Southern-inspired dinner, serve it with mashed potatoes, green beans, and extra Coca-Cola glaze.
Make-Ahead Instructions
The marinade can be prepared a day ahead and the pork can marinate overnight.
You can also prepare the glaze ahead of time and refrigerate it.
Reheat the glaze gently in a saucepan before using.
Storage
Store leftover pork in an airtight container in the refrigerator for up to 4 days.
For longer storage, freeze the cooled pork in a freezer-safe container for up to 3 months.
To reheat, cover the pork with foil and warm gently in a 350°F (175°C) oven until heated through.
Frequently Asked Questions
Does Coca-Cola make the pork taste like soda?
Not strongly. The Coca-Cola contributes a subtle sweetness and caramel-like flavor rather than making the pork taste like a soft drink.
Can I use pork shoulder instead?
Yes, although pork shoulder has considerably more fat and will require a different cooking approach and longer cooking time.
Can I use Diet Coke?
Some versions suggest sugar-free cola as an alternative, but regular Coca-Cola is preferable when you want the traditional caramelized glaze.
Can I make this in a slow cooker?
Yes, although the traditional recipe is roasted. A slow-cooker adaptation can produce very tender pork, but the exterior won’t caramelize in quite the same way unless you finish it under high heat.
Final Thoughts
Old South Coca-Cola Pork Loin is a memorable centerpiece for a Southern-style dinner. The combination of savory soy sauce, tangy mustard, garlic, herbs, Coca-Cola, brown sugar, and balsamic vinegar creates layers of flavor, while the finishing glaze gives the pork a beautiful caramelized coating.
Slice it thickly, spoon the glossy glaze over the top, and serve it alongside mashed potatoes and your favorite vegetables for a comforting homemade meal
