Ingredients Notes
The quality of your pork tenderloin can greatly impact the flavor, so consider sourcing it from a butcher or a reputable meat supplier. For the sweet potatoes, choose firm ones with smooth skin for the best texture. A sprinkling of fresh rosemary and thyme can elevate this dish, but if fresh herbs are unavailable, dried alternatives work well too. A drizzle of olive oil helps the flavors meld perfectly during roasting.
Recipe Steps
Step 1
Preheat your oven to 400°F (200°C). While waiting, rinse the pork tenderloin under cold water and pat dry with paper towels.
Step 2
In a small bowl, combine olive oil, minced garlic, salt, pepper, and chopped rosemary. Rub this mixture all over the pork tenderloin.
Step 3
Peel and dice the sweet potatoes into even chunks. Toss them with olive oil, salt, and pepper, ensuring they are well-coated.

Step 4
Place the seasoned pork in the center of a large baking sheet, arranging the sweet potatoes around it. Roast for about 25-30 minutes.
Step 5
Check the pork’s internal temperature—it should reach 145°F (63°C). Let it rest for 5 minutes before slicing and serving with the roasted sweet potatoes.
Storage Options
To store, place leftovers in an airtight container and refrigerate for up to three days. For longer storage, slice the pork and freeze in individual portions along with the sweet potatoes. Reheat in the oven or microwave, adding a splash of broth or water to maintain moisture.
Variations & Substitutions
For a different flavor profile, try using Dijon mustard in the marinade or swap sweet potatoes with butternut squash. If you prefer a spicier kick, add a pinch of cayenne. For those avoiding pork, this recipe works beautifully with chicken breasts.
Serving Suggestions
This dish is a fantastic centerpiece for a cozy dinner. Pair it with a fresh green salad or steamed vegetables for a complete meal. It’s also a delightful choice for a holiday feast, offering a lighter alternative to traditional roasts.
Frequently Asked Questions
Can I use a different cut of pork for this recipe? Absolutely, you can use pork loin if tenderloin is unavailable. Just adjust the cooking time, as pork loin is thicker and may require a longer roasting period.
Are there alternative seasonings that work well? Yes, if you’re out of rosemary, try thyme or sage. For a hint of heat, add some smoked paprika or chili flakes to the seasoning mix.
How can I ensure the pork stays juicy? The key is not to overcook it. Using a meat thermometer can help ensure it’s cooked perfectly. Letting the meat rest after roasting allows the juices to redistribute, keeping it tender and juicy.
