Ingredient Notes

Pork Loin Roast

A boneless pork loin roast is the centerpiece of this recipe. A larger roast is ideal when you are feeding a family or preparing dinner for guests.

Make sure you distinguish between pork loin and pork tenderloin. They are different cuts and have very different sizes and cooking times.

Coca-Cola

Regular Coca-Cola provides sweetness and contributes to the flavor of both the marinade and glaze. The classic recipe uses regular Coca-Cola rather than diet soda.

Dark Brown Sugar

Dark brown sugar adds sweetness and a deeper molasses-like flavor to the marinade. It also helps create a beautifully caramelized exterior during roasting.

Dijon Mustard

Dijon mustard adds tanginess and helps balance the sweetness of the Coca-Cola and brown sugar.

Worcestershire Sauce

Worcestershire sauce provides savory depth and complements the pork beautifully.

Balsamic Vinegar

Balsamic vinegar contributes acidity and balances the sweetness of the glaze. It also adds another layer of complexity to the finished sauce.

Garlic, Ginger, and Thyme

These aromatics add warmth and fragrance to the marinade, helping prevent the pork from tasting overly sweet.

How to Make Old South Coca-Cola Pork Loin

Step 1: Make the Marinade

In a large bowl, baking dish, or large resealable bag, combine the soy sauce, Coca-Cola, dark brown sugar, Dijon mustard, oil, Worcestershire sauce, ketchup, minced garlic, dry mustard, balsamic vinegar, ginger, and crushed thyme.

Whisk or stir until the ingredients are well combined and the brown sugar has started to dissolve.

Step 2: Add the Pork Loin

Place the pork loin roast into the marinade. Turn the roast several times so that the marinade coats as much of the surface as possible.

If using a resealable bag, place the bag inside a large bowl or container to prevent leaks and make handling easier.

Step 3: Marinate Overnight

Seal the bag or cover the baking dish and refrigerate the pork overnight, ideally for up to about 24 hours. Turn the roast several times during the marinating process.

Keeping the pork refrigerated during marinating is important for food safety.

Why Marinate Pork Loin Overnight?

The overnight marinade gives the pork time to absorb the flavors of the Coca-Cola, mustard, garlic, soy sauce, Worcestershire sauce, balsamic vinegar, and spices.

It also allows the sweet and savory flavors to become more integrated before the roast enters the oven.

Step 4: Preheat the Oven

Preheat your oven to 325°F (163°C).

Remove the pork from the refrigerator and take it out of the marinade.

Discard the used marinade. Because it has been in contact with raw pork, do not use it as a finishing sauce unless it is separately cooked to a safe temperature.

Step 5: Prepare the Pork for Roasting

Place the pork loin fat-side up on a rack inside a roasting pan.

Insert a meat thermometer into the thickest part of the roast. Try to position the thermometer in the center of the meat without touching bone.

There is no need to add water to the roasting pan, and the traditional preparation leaves the roast uncovered.

Step 6: Roast the Pork

Place the pork in the preheated oven and roast until it reaches the appropriate internal temperature.

Cooking time will vary depending on the exact size and shape of your roast, so use a meat thermometer rather than relying only on minutes per pound.

For a whole pork loin roast, the USDA recommends cooking to a minimum internal temperature of 145°F (63°C), followed by at least a 3-minute rest.

Step 7: Prepare the Coca-Cola Glaze

While the pork is roasting, prepare the glaze.

Combine the brown sugar, cornstarch, dry mustard, butter, balsamic vinegar, Coca-Cola, sea salt, and freshly ground black pepper in a saucepan.

Place the saucepan over medium heat and stir as the mixture warms.

Bring it to a gentle simmer and continue stirring until the glaze thickens and becomes glossy.

Why the Glaze Makes This Pork So Special

The glaze is what gives this pork roast its signature finish.

The brown sugar and Coca-Cola create sweetness, while balsamic vinegar adds acidity. Butter contributes richness, and dry mustard adds a subtle sharp flavor.

As the glaze cooks down, it becomes thicker and more concentrated, making it ideal for brushing over the pork during the final stage of roasting.

Step 8: Glaze During the Final Stage

During approximately the final 30 minutes of cooking, brush or spoon the Coca-Cola glaze over the pork.

Apply the glaze generously, but keep an eye on the roast because the sugar can caramelize quickly.

You can brush the pork several times during the final cooking period to build a beautiful glossy coating.

Step 9: Rest the Pork

Once the pork has reached the desired internal temperature, remove it from the oven and place it on a serving platter or cutting board.

Loosely tent the roast with foil and allow it to rest for at least 3 minutes, with a longer rest of around 10–15 minutes often making carving easier.

Resting allows the juices to redistribute and helps the slices remain moist.

Step 10: Slice and Serve

Use a sharp carving knife to slice the pork loin into even pieces.

Arrange the slices on a platter and spoon some of the remaining glaze over the top. Any extra glaze can be served alongside the pork.

What Does Coca-Cola Do to Pork?

Coca-Cola contributes sweetness and flavor to the marinade and glaze. When combined with brown sugar and cooked, it also contributes to the caramelized exterior.

The finished pork should not taste like a glass of Coca-Cola. Instead, the cola becomes one part of a balanced combination of sweet, savory, tangy, and aromatic flavors.

Does Coca-Cola Tenderize Pork?

The marinade contributes flavor and moisture, and its acidic ingredients can influence the surface of the meat. However, the final tenderness of pork loin depends heavily on the cut, cooking temperature, internal temperature, and resting time.

The most important way to achieve juicy pork is to avoid overcooking it and to monitor its internal temperature with a reliable meat thermometer.

How to Get the Best Caramelized Glaze

Because the glaze contains sugar, timing is important.

Instead of applying a thick sugary coating at the beginning of roasting, add the glaze toward the end. This gives it enough time to caramelize without exposing the sugars to prolonged high heat.

If the surface begins to darken too quickly, loosely cover the roast with foil while it finishes cooking.

Best Tips for Juicy Coca-Cola Pork Loin

Choose a fresh pork loin roast with a good shape for even cooking.
Marinate the pork overnight for maximum flavor.
Keep the pork refrigerated during marinating.
Discard the used marinade.
Use a meat thermometer to check doneness.
Do not rely exclusively on cooking time.
Prepare the glaze separately.
Apply the glaze during the final stage of cooking.
Watch carefully because the glaze contains sugar.
Let the pork rest before slicing.
Use a sharp knife for clean slices.

What to Serve With Old South Coca-Cola Pork Loin

This pork roast pairs beautifully with classic comfort-food side dishes. Because the pork has a sweet and savory glaze, simple sides work especially well.

Mashed potatoes
Roasted potatoes
Green beans
Roasted carrots
Sweet potatoes
Macaroni and cheese
Coleslaw
Cornbread
Steamed broccoli
Roasted Brussels sprouts
Garden salad

Coca-Cola Pork Loin With Mashed Potatoes

Creamy mashed potatoes are one of the best side dishes for glazed pork loin. Their mild, buttery flavor balances the sweetness of the Coca-Cola glaze.

Add a spoonful of extra glaze over the pork and let a little run onto the mashed potatoes for an especially comforting dinner.

Coca-Cola Pork Loin With Green Beans

Fresh green beans provide a simple vegetable side that complements the richness of the pork.

Keep the seasoning simple with butter, salt, pepper, or a little garlic.

Coca-Cola Pork Loin With Sweet Potatoes

Sweet potatoes enhance the caramelized flavors of the pork. Serve them roasted, mashed, or baked.

For a less sweet plate, balance the meal with green vegetables or a crisp salad.

Perfect Sunday Dinner

This Southern pork loin recipe is ideal for Sunday dinner because the marinade can be prepared the night before.

On cooking day, the pork simply needs to be removed from the marinade, placed in the oven, and glazed during the final stage.

While the pork roasts, you can prepare potatoes and vegetables so everything is ready around the same time.

Perfect Holiday Pork Roast

If you are looking for an alternative to the usual holiday ham or turkey, Coca-Cola pork loin can make an impressive centerpiece.

The glossy glaze gives the roast a beautiful presentation, while the sliced pork is easy to serve to a crowd.

Add roasted vegetables, mashed potatoes, dinner rolls, and a fresh salad for a complete holiday meal.

Can I Use Pork Tenderloin?

Yes, but pork tenderloin is much smaller and cooks significantly faster than a large pork loin roast.

If you substitute tenderloin, do not follow the cooking time intended for a five-pound pork loin. Instead, adjust the cooking time and use a meat thermometer to determine when it is done.

Can I Use a Smaller Pork Loin?

Absolutely. A smaller pork loin works well, especially when cooking for a smaller family.

You can reduce the marinade and glaze quantities if desired, although making the full amount of glaze can be useful if you want extra sauce for serving.

Can I Use a Bone-In Pork Loin?

A bone-in pork loin can be used, but the shape and cooking time will be different from a boneless roast.

Use the internal temperature as your primary guide rather than attempting to follow the exact timing of the original recipe.

Can I Make This Recipe in a Slow Cooker?

The classic Old South Coca-Cola Pork Loin is an oven-roasted recipe. A slow cooker can be used for other Coca-Cola pork variations, but the cooking method, liquid level, and timing need to be changed for the appliance.

If you want the signature caramelized exterior, finishing the pork under an oven broiler or in a hot oven may help, but watch the sugary glaze closely.

Can I Grill Coca-Cola Pork Loin?

Some versions of this recipe can be adapted for grilling or smoking. However, cooking a large pork loin over a grill requires careful temperature control.

Use indirect heat and monitor the internal temperature carefully. Apply sugary glaze toward the end to reduce the chance of burning.

How to Make a Spicy Coca-Cola Pork Loin

If you enjoy sweet and spicy flavors, add a small amount of cayenne pepper, crushed red pepper flakes, chili powder, or hot sauce to the marinade or glaze.

The heat creates a delicious contrast with the sweetness of the Coca-Cola and brown sugar.

Garlic Coca-Cola Pork Loin

For a stronger garlic flavor, increase the amount of fresh minced garlic in the marinade.

Fresh garlic pairs especially well with Worcestershire sauce, soy sauce, mustard, and balsamic vinegar.

Orange Coca-Cola Pork Loin

For a citrus-inspired variation, add a little orange zest to the glaze.

The fresh citrus aroma cuts through the richness of the pork and works beautifully with caramelized flavors.

Can I Use Diet Coca-Cola?

Some variations use sugar-free cola, but the glaze and caramelization can behave differently because regular Coca-Cola contributes sugar.

For the classic version of this recipe, regular Coca-Cola is the better choice.

Can I Use Another Cola?

Yes. Another regular dark cola can work as a substitute, although the final flavor will vary slightly.

For the closest result to the classic recipe, use regular Coca-Cola.

How to Store Leftover Coca-Cola Pork Loin

Place leftover pork in an airtight container and refrigerate it promptly.

If you have extra glaze, store it separately whenever possible.

Keeping the glaze separate allows you to reheat the pork without making the exterior excessively soft.

How to Reheat Pork Loin Without Drying It Out

Slice the pork before reheating if you are only warming a portion.

Place the slices in a covered baking dish with a small amount of glaze or another suitable liquid. Heat gently until warmed through.

For individual servings, the microwave can also work. Use short intervals and avoid overheating the pork.

How to Use Leftover Coca-Cola Pork

Leftover pork can become the foundation for several quick meals.

Pork sandwiches
BBQ-style pork sliders
Rice bowls
Salads
Wraps
Quesadillas
Loaded baked potatoes
Breakfast hash

Coca-Cola Pork Sandwiches

Thinly slice leftover pork and serve it on toasted buns with extra glaze.

Add coleslaw, pickles, caramelized onions, or a little mustard for a delicious leftover sandwich.

How to Make the Glaze Thicker

The cornstarch in the glaze helps it thicken as it heats.

If the glaze is still too thin after simmering, continue cooking gently until some of the liquid evaporates and the sauce reaches a glossy, spoon-coating consistency.

How to Prevent the Glaze From Burning

The glaze contains brown sugar and Coca-Cola, so it can burn if exposed to high heat for too long.

Apply it during the last part of cooking and monitor the pork closely.

If the top becomes too dark before the pork reaches its target internal temperature, loosely cover it with foil.

Common Mistakes to Avoid

Skipping the Overnight Marinade

The overnight marinade is one of the defining features of this recipe. It gives the pork time to develop its sweet and savory flavor.

Using the Raw Marinade as Sauce

Never serve the marinade directly after it has been in contact with raw pork. Discard it, or if you intend to turn it into a sauce, cook it separately and thoroughly according to safe food-handling practices.

Overcooking the Pork

Pork loin is relatively lean, so overcooking can make it dry. Use a meat thermometer and remove it when it reaches the recommended safe internal temperature.

Glazing Too Early

Adding the glaze too early can cause the sugars to burn before the pork is fully cooked.

Slicing Immediately

Allow the pork to rest before slicing. This helps preserve moisture and makes carving easier.

How to Get Beautiful Slices

Use a sharp carving knife and make steady, even cuts.

If possible, slice across the grain of the meat. This can make each bite feel more tender.

How to Make This Pork Roast for a Crowd

A large pork loin is a practical option when serving several people.

Prepare the marinade the day before and refrigerate the pork overnight. On the day of the meal, roast the pork while preparing your side dishes.

Once the roast reaches the proper internal temperature, allow it to rest before carving. Arrange the slices on a large platter and spoon extra glaze over the top.

Make-Ahead Tips

Prepare the marinade the night before.
Marinate the pork overnight.
Prepare the glaze ahead of time and refrigerate it if needed.
Reheat the glaze gently before using.
Slice leftovers for easy lunches.
