Key Ingredients for an Unforgettable Meal
Crafting this delightful Roasted Pork Tenderloin with Mustard Sauce begins with selecting the right ingredients. Each component plays a crucial role in building the layered flavors that make this dish so special. Here’s a closer look at what you’ll need and why it matters:
Flavorful Spices: The foundation of our pork’s savory profile comes from a thoughtfully blended mix of granulated garlic, dried oregano, ground coriander, ground cumin, salt, and pepper. This aromatic combination creates a robust rub that penetrates the meat overnight, enhancing its natural flavor. While this blend is fantastic, feel free to adjust the ratios or add your favorite spices like smoked paprika or a touch of cayenne for an extra kick. Freshly ground spices will always offer a more vibrant aroma and taste.
Pork Tenderloin: This cut is celebrated for its lean, tender texture and quick cooking time, making it an excellent choice for roasting. Unlike a larger pork loin roast, tenderloins are smaller and more delicate, perfect for absorbing the spice rub and cooking evenly alongside the potatoes. When selecting, look for tenderloins that are pinkish-red with no signs of dryness. A typical package often contains two tenderloins, totaling 2.5 to 3 pounds, which is ideal for feeding a family or having delicious leftovers.
Baby Red Potatoes: These small, unpeeled red potatoes are perfect for roasting. Their thin skin becomes wonderfully tender when cooked, eliminating the need for peeling. Their naturally buttery flavor and creamy texture make them an ideal accompaniment to the savory pork. Cutting them into uniform 1-inch pieces ensures they roast evenly and achieve that desired crisp exterior and soft interior. Feel free to experiment with other small, waxy potatoes if red potatoes aren’t available, but avoid starchy varieties like Russets, which can become too mealy.
Crispy Bacon: This isn’t just a garnish; it’s a critical flavor component! As the bacon roasts alongside the potatoes, its savory fat renders, infusing the potatoes with an irresistible smoky depth. The crispy bacon bits themselves provide a fantastic textural contrast to the tender pork and soft potatoes. Four slices, cut into 1/2-inch pieces, are all you need to impart a significant amount of flavor.
Olive Oil: Extra virgin olive oil serves two purposes in this recipe: it helps bind the spices to the pork and coats the potatoes and bacon, promoting even roasting and beautiful browning. Its fruity notes complement the other ingredients without overpowering them. If you prefer, avocado oil is an excellent alternative due to its high smoke point and neutral flavor.
Fresh Parsley: Essential for the vibrant mustard sauce, fresh parsley adds a burst of herbaceous freshness that brightens the rich flavors of the pork and potatoes. I strongly recommend using fresh parsley over dried in this instance, as the dried version lacks the same lively aroma and delicate texture that the sauce requires. Chop it finely to ensure it disperses evenly throughout the sauce.
Shallot: Often described as a milder, sweeter cousin to the onion, a minced shallot provides a delicate allium flavor to the mustard sauce. Its subtle sweetness and nuanced aroma perfectly complement the tanginess of the mustard and vinegar. If shallots are hard to find, a very small amount of finely minced yellow onion can be substituted, though be mindful that onion has a stronger, sharper taste.
Whole-Grain Mustard: The true star of the sauce! Whole-grain mustard offers a delightful texture from the crushed mustard seeds and a complex, tangy flavor that is both pungent and slightly sweet. Its robust character stands up beautifully to the roasted pork. While regular yellow mustard is too mild, Dijon mustard can be used as a substitute if whole-grain is unavailable, providing a similar level of tanginess, albeit without the texture.
White Wine Vinegar: This ingredient adds a crucial acidic brightness to the mustard sauce, cutting through the richness of the pork and balancing the flavors. White wine vinegar is subtle and elegant, but apple cider vinegar or red wine vinegar can also work as suitable alternatives, each contributing a slightly different fruity or robust note.
A Pinch of Sugar: Just a touch of sugar is added to the mustard sauce to balance the acidity of the vinegar and mustard. It’s not meant to make the sauce sweet but rather to round out the flavors and prevent it from being overly sharp. A pinch is truly all you need!
Frequently Asked Questions About Roasting Pork Tenderloin
Here are some common questions to help you master this delicious Roasted Pork Tenderloin recipe:
The baking time for pork tenderloin can vary based on its size and your oven, but in this specific recipe, we cook it at a lower temperature (325ºF) initially to allow the potatoes ample time to roast and crisp up. You’ll roast the pork tenderloin until its internal temperature reaches 130ºF, which typically takes about 20-25 minutes. Following this, a quick broil will finish cooking the pork to perfection, achieving a lovely browned exterior and ensuring it’s cooked through to a safe temperature. Always use a meat thermometer for accuracy.
For optimal tenderness and safety, pork tenderloin is considered fully cooked and safe to eat when its internal temperature reaches 145ºF. To achieve this, I recommend removing the pork from the oven when it registers 140ºF. Then, cover it loosely with foil and let it rest for 10-15 minutes. This resting period is crucial, as the carryover heat will continue to cook the pork, allowing it to reach the ideal 145ºF while also redistributing the juices, resulting in a more succulent and flavorful cut. A slight pink in the center is perfectly normal and a sign of a perfectly cooked, tender pork tenderloin.
Any leftover roasted pork tenderloin and potatoes should be refrigerated promptly within two hours of cooking. I find it convenient to store the pork and potatoes together in an airtight container. However, for the best flavor and texture, the mustard sauce should be stored separately in its own sealed container. Properly stored, the leftovers will remain fresh for 3-4 days in the refrigerator. Reheat gently in the oven or microwave, being careful not to overcook the pork.

Tips for Achieving Perfect Roasted Pork Tenderloin
To ensure your roasted pork tenderloin turns out exceptionally tender and flavorful every time, consider these expert tips:
- Trim Properly: Before seasoning, always trim any silver skin or excess fat from the pork tenderloin. Silver skin is a tough membrane that won’t render during cooking and can make the meat chewy. A sharp knife can easily slide underneath it to remove it.
- Even Thickness: Pork tenderloins can sometimes be thicker at one end. To ensure even cooking, you can gently pound the thicker parts to a more uniform thickness or tuck the thinner tail end under and tie it with kitchen twine. This prevents the thinner parts from overcooking and drying out.
- Don’t Skimp on Seasoning: The dry rub is key to building flavor. Make sure to generously coat the entire surface of the pork tenderloin. The overnight refrigeration allows the flavors to penetrate deeply.
- Rest Your Meat: This step is non-negotiable for juicy pork! After removing the pork from the oven, tent it loosely with foil and let it rest for at least 10-15 minutes. This allows the muscle fibers to relax and redistribute the juices throughout the meat, resulting in a more tender and moist outcome. If you slice it too soon, the juices will run out, leaving you with dry pork.
- Use a Meat Thermometer: The only reliable way to ensure pork is cooked to perfection and safely is with a good meat thermometer. Digital instant-read thermometers are highly recommended. Aim for an internal temperature of 140°F before resting, which will rise to 145°F.
- Broiling for Color: The final broil step is crucial for achieving a beautiful golden-brown crust on both the pork and the potatoes. Keep a close eye on the oven during this stage, as broilers can quickly burn food.
Serving Suggestions & Variations
While this dish is a complete meal with the roasted potatoes, here are a few ideas to enhance your dining experience or explore new flavors:
- Complementary Sides: Beyond the potatoes, consider serving with steamed green beans, asparagus, a simple garden salad with a light vinaigrette, or roasted carrots for extra vegetables and color.
- Bread: A crusty bread is perfect for soaking up any extra mustard sauce or pan juices.
- Wine Pairing: A crisp white wine like Sauvignon Blanc or a light-bodied red such as Pinot Noir would beautifully complement the flavors of the pork and mustard sauce.
- Herb Variations: Experiment with different dried herbs in the rub. Rosemary or thyme would offer an earthier profile, while a touch of smoked paprika could add a subtle smoky sweetness.
- Spicier Sauce: For those who enjoy a little heat, a pinch of red pepper flakes or a dash of hot sauce can be added to the mustard sauce.
- Different Potatoes: While baby red potatoes are fantastic, small Yukon Gold potatoes or even quartered fingerling potatoes would also work wonderfully.

Roasted Pork Tenderloin with Mustard Sauce
Pin Recipe
Ingredients
- 1 1/2 teaspoons granulated garlic
- 1 1/2 teaspoons dried oregano
- 1 1/2 teaspoons ground coriander
- 1 1/2 teaspoons ground cumin
- Salt and pepper, to taste
- 2 pork tenderloins (2 1/2 – 3 lbs total)
- 2 1/2 lbs small red potatoes, unpeeled, cut into 1-inch pieces
- 4 slices bacon, cut into 1/2-inch pieces
- 6 tablespoons extra virgin olive oil, divided
- 1/4 cup minced fresh parsley
- 1 shallot, minced
- 2 tablespoons whole-grain mustard
- 1 1/2 tablespoons white wine vinegar
- Pinch of sugar
Instructions
- In a small bowl, combine the granulated garlic, oregano, coriander, and cumin. Add 1/2 teaspoon salt and 1/2 teaspoon pepper. Rub this spice mix generously all over the pork tenderloins and wrap them tightly with plastic wrap.
- Place the cut potatoes, bacon pieces, and 2 tablespoons of the olive oil in a large ziplock bag. Toss thoroughly to coat all the ingredients. Press out as much air as possible from the bag.
- In a separate small bowl, combine the remaining 1/4 cup olive oil, minced fresh parsley, minced shallot, whole-grain mustard, white wine vinegar, and a pinch of sugar. Stir well to combine. Cover the bowl.
- Store the seasoned pork tenderloins, the bag of potatoes and bacon, and the covered mustard dressing in the refrigerator for at least 1 hour, or up to 24 hours, to allow flavors to meld.
- When you’re ready to cook and serve, remove the mustard dressing from the refrigerator and allow it to come to room temperature while you prepare the oven.
- Adjust an oven rack to the upper-middle position and preheat your oven to 325ºF (160ºC). Line a large baking sheet with foil for easy cleanup and spray it lightly with nonstick cooking spray.
- Spread the seasoned potatoes and bacon onto the prepared baking sheet in a single layer. Season with additional salt and pepper to taste. Roast the potatoes for 30 minutes.
- Carefully remove the baking sheet from the oven. Using a spoon or spatula, push the roasted potatoes and bacon to the sides of the baking sheet to create space in the center. Pat the pork tenderloins dry with paper towels (this helps create a better crust) and place them in the center of the baking sheet.
- Return the baking sheet to the oven and continue to roast until the pork tenderloin registers 130ºF (54ºC) on an instant-read thermometer, which should take approximately 20-25 minutes.
- Remove both the pork and potatoes from the oven. Adjust the oven rack so it is about 6 inches from the broiler element. Switch your oven setting to broil.
- Return the baking sheet to the oven under the broiler. Broil the pork and potatoes until the pork develops a spotty brown crust and its internal temperature reaches 140ºF (60ºC), typically 3-5 minutes. Watch carefully to prevent burning.
- Transfer the pork tenderloins to a clean cutting board and tent them loosely with foil. Let the pork rest for 10-15 minutes. While the pork rests, return the potatoes to the oven and continue to broil for an additional 5-10 minutes, or until they are lightly browned and tender.
- After resting, slice the pork tenderloins into 1/2-inch thick medallions. Serve the sliced pork and roasted potatoes immediately, drizzled generously with the prepared mustard sauce.
