What Cut of Pork Should I Use?

For this dish, pork tenderloin is the star. It’s lean, cooks quickly, and stays juicy when not overdone. Be careful not to confuse it with pork loin—a different cut that requires longer cooking times. The tenderloin’s mild flavor is a perfect canvas for the bold balsamic glaze.

Ingredients for the Balsamic Pork Tenderloin in Oven

2 pork tenderloins (1 to 1.5 lbs each)
1/4 cup balsamic vinegar
3 tablespoons olive oil
3 tablespoons brown sugar
1 tablespoon Dijon mustard
3 garlic cloves, minced
1 teaspoon dried rosemary (or thyme)
1 teaspoon salt
1/2 teaspoon black pepper
Optional: 1 tablespoon soy sauce for deeper umami

How To Make the Balsamic Pork Tenderloin in Oven

Step 1: Prep the Marinade

In a small bowl, whisk together balsamic vinegar, olive oil, brown sugar, Dijon mustard, garlic, rosemary, salt, pepper, and soy sauce (if using). Set aside.

Step 2: Marinate the Pork

Pat pork tenderloins dry. Place them in a zip-top bag or shallow dish and pour in the marinade. Let sit for at least 30 minutes, or refrigerate overnight for deeper flavor.

Step 3: Sear for Extra Flavor

Preheat oven to 400°F (200°C). In an oven-safe skillet over medium-high heat, sear the tenderloins on all sides for 5-6 minutes until golden brown.

Step 4: Roast to Perfection

Transfer the skillet to the oven. Roast for 18-22 minutes, or until the internal temperature reaches 145°F (63°C). Let rest for 5-10 minutes before slicing.

Step 5: Reduce the Glaze (Optional)

While the pork rests, pour the leftover marinade into a small saucepan. Simmer over medium heat for 5-7 minutes until thickened. Drizzle over sliced pork.

How to Serve and Store Balsamic Pork Tenderloin

This pork is delicious served hot with your favorite starches and vegetables—think creamy polenta, herbed couscous, or roasted carrots. It’s also fantastic sliced thin for sandwiches or salads the next day.

Store leftovers in an airtight container in the fridge for up to 3 days. Reheat gently in the oven or microwave to maintain moisture. You can also freeze cooked pork slices for up to 2 months—just thaw overnight in the fridge before reheating.

Frequently Asked Questions

Can I use pork loin instead?

No, pork loin is thicker and requires longer cooking time. Stick to tenderloin for best results.

Is it necessary to sear the pork?

Searing locks in juices and adds flavor but can be skipped if you’re short on time.

Can I grill this instead of roasting?

Absolutely! Grill over medium heat, turning every few minutes, until the internal temp reaches 145°F.

What can I substitute for balsamic vinegar?

Try red wine vinegar with a touch of honey or maple syrup for a similar tangy-sweet balance.

Should I let the pork rest before slicing?

Yes, resting helps redistribute juices so the meat stays moist.

Is the glaze safe to eat after marinating raw pork?

Only if you simmer it until it reaches a boil—this kills any bacteria.
