1 tablespoon olive oil
2 lbs pork tenderloin

Instructions

Begin by preparing the marinade. In a mixing bowl, thoroughly combine the following dried herbs and spices: thyme, marjoram, sage, garlic powder, onion powder, and ground ginger. Ensure there are no clumps and the mixture is uniform. This aromatic blend will infuse the pork with deep, savory notes.
To the herb and spice mixture, add the wet ingredients: soy sauce, Worcestershire sauce, and olive oil. Combine all the ingredients thoroughly until a smooth, emulsified marinade is achieved. The soy sauce will contribute umami and saltiness, while the Worcestershire sauce adds a tangy depth, and the olive oil helps to distribute the flavors and keep the pork moist during roasting.
Place the pork tenderloin in a resealable plastic bag or a shallow dish. Pour the prepared marinade evenly over the pork loin, ensuring that all sides are well coated. Gently massage the marinade into the meat.
Marinate the pork tenderloin in the refrigerator for at least 8 hours. This extended marinating time allows the flavors to penetrate deeply into the meat, resulting in a more flavorful and tender final product. Turn the bag or pork loin occasionally to ensure even marination.
When ready to cook, preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). It’s crucial to ensure your oven is properly preheated to maintain consistent cooking temperatures.
Remove the pork tenderloin from the refrigerator and allow it to come to room temperature for about 20 minutes. This step helps the pork cook more evenly.
Place the marinated pork tenderloin in a roasting pan. There’s no need to cover the pan with foil. Roasting uncovered allows the exterior of the pork to develop a beautiful crust while maintaining a moist interior.
Roast the pork tenderloin in the preheated oven for approximately 45 minutes. However, cooking time may vary depending on the thickness of the pork and the accuracy of your oven. Use a meat thermometer to accurately measure the internal temperature.
To ensure the pork tenderloin is cooked to perfection, use a meat thermometer inserted into the thickest part of the loin. The internal temperature should reach 145 degrees Fahrenheit (63 degrees Celsius) for medium-rare, or slightly higher for desired doneness.
Once the pork tenderloin has reached the desired internal temperature, remove it from the oven and transfer it to a cutting board. Tent loosely with foil and let it rest for 15 minutes before carving. This resting period is essential as it allows the juices to redistribute throughout the meat, resulting in a more tender and flavorful final product.
After resting, carve the pork tenderloin into ¼ inch slices. Use a sharp knife to achieve clean, even slices.

Expert Tips & Tricks

For extra flavor, consider adding a teaspoon of smoked paprika to the dry rub. It adds a wonderful smoky depth.
Don’t skip the resting period! It’s vital for a juicy and tender roast.
If you’re short on time, you can marinate the pork for as little as 4 hours, but the longer the better.
To prevent the pork from drying out during cooking, you can add a splash of chicken broth or wine to the bottom of the roasting pan.
If the pork starts to brown too quickly, you can loosely tent it with foil during the last 15 minutes of cooking.

Serving & Storage Suggestions

Serve the roasted pork tenderloin immediately after carving. It pairs beautifully with roasted vegetables like asparagus, Brussels sprouts, or sweet potatoes. Mashed potatoes or rice are also excellent side dishes. For a complete meal, consider serving it with a green salad and a crusty bread.

Leftover roast pork tenderloin can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, gently warm the slices in a skillet with a little olive oil or in the microwave. Avoid overheating, as this can dry out the meat.

For longer storage, the cooked pork tenderloin can be frozen for up to 2-3 months. Wrap it tightly in plastic wrap and then in foil to prevent freezer burn. Thaw overnight in the refrigerator before reheating.

FAQs (Frequently Asked Questions)

Q: Can I marinate the pork tenderloin for longer than 8 hours?
A: Yes, you can marinate it for up to 24 hours for a more intense flavor. However, avoid marinating it for much longer, as the acid in the marinade can start to break down the meat fibers and make it mushy.

Q: How do I know when the pork tenderloin is done?
A: The best way is to use a meat thermometer inserted into the thickest part of the loin. The internal temperature should reach 145 degrees Fahrenheit (63 degrees Celsius) for medium-rare.

Q: Can I use a different cut of pork for this recipe?
A: While this marinade works well with other cuts, pork tenderloin is ideal because it is lean and cooks quickly. Pork loin roast would be a good alternative, but it will require a longer cooking time.

Q: What if I don’t have all the herbs in the recipe?
A: Don’t worry! You can adjust the amounts of the herbs you do have, or use a pre-made herb blend like Italian seasoning.

Q: Can I grill the pork tenderloin instead of roasting it?
A: Yes, you can grill it. Preheat your grill to medium-high heat and grill the pork tenderloin for about 15-20 minutes, turning occasionally, until it reaches an internal temperature of 145 degrees Fahrenheit.
