Hearty Roasted Pork Loin & Vegetables: Easy Recipe

This hearty roasted pork loin is served with golden potatoes, sweet carrots, and tender onions, all seasoned with garlic, rosemary, and paprika. Roasting the vegetables before adding the pork gives them a head start, while a thermometer keeps the meat juicy and safely cooked. It is a flexible, one-pan-style dinner with familiar ingredients and plenty of savory pan juices.

Ingredients

1 boneless pork loin roast, about 2½ lb (1.13 kg), trimmed of excess surface fat
1½ lb Yukon Gold or red potatoes, cut into 1½-inch (4 cm) chunks (680 g)
4 medium carrots, peeled and cut into 1½-inch (4 cm) pieces, about 12 oz (340 g)
1 large yellow onion, cut into 8 wedges, about 10 oz (280 g)
3 tbsp olive oil (45 ml), divided
4 garlic cloves, finely grated or minced, about 1 tbsp (10 g)
1½ tsp kosher salt (about 8 g), divided, plus more to taste
1 tsp freshly ground black pepper (about 2 g), divided
1 tsp dried rosemary (1 g), or 1 tbsp finely chopped fresh rosemary (3 g)
1 tsp dried thyme (1 g), or 1 tbsp finely chopped fresh thyme (3 g)
1 tsp sweet paprika (2 g)
½ cup low-sodium chicken broth or water (120 ml)
1 tbsp chopped fresh parsley (4 g), optional, for serving

Instructions

Heat the oven and prepare the pan. Set a rack in the middle of the oven and heat it to 425°F (220°C). Use a large, sturdy roasting pan or rimmed sheet pan that gives the vegetables room to brown. If the pan is crowded, divide the vegetables between two pans; packed vegetables steam instead of roasting. Pat the pork dry with paper towels and set it aside while you prepare the vegetables.
Season and start the vegetables. Put the potatoes, carrots, and onion in the pan. Toss with 2 tablespoons (30 ml) of the olive oil, ¾ teaspoon of the salt, and about half the pepper. Spread everything in one layer with cut sides facing down where possible. Roast for 20 minutes. This head start helps the denser vegetables soften without requiring the pork to stay in the oven too long.
Season the pork. While the vegetables roast, combine the remaining 1 tablespoon (15 ml) olive oil with the garlic, rosemary, thyme, paprika, remaining ¾ teaspoon salt, and remaining pepper. Rub the mixture over all sides of the pork. If the roast is tied with butcher’s twine, leave the twine in place during roasting so it holds an even shape; remove it before slicing.
Add the roast and broth. After the vegetables have roasted for 20 minutes, remove the pan carefully. Stir the vegetables and move them toward the edges to make space in the center. Set the pork in the open space, fat side up if it has a fat cap. Pour the broth into the pan around the vegetables, not over the seasoned pork. The liquid helps keep browned bits from scorching and gives you a little flavorful juice for serving.
Roast until done. Return the pan to the oven and roast for about 45 to 60 minutes, checking the pork after 40 minutes because the shape of the loin and individual ovens affect the timing. Turn the vegetables once if they are browning unevenly. Insert an instant-read thermometer into the thickest part of the pork, avoiding the pan and any fat. USDA FSIS guidance sets the safe minimum for whole cuts of pork at 145°F (63°C), followed by a 3-minute rest; cook to that temperature and verify it with the thermometer rather than relying on color. If the vegetables are tender and nicely browned before the pork is ready, transfer them to a serving dish and keep them loosely covered while the roast finishes.
Rest, then carve. Transfer the pork to a cutting board and let it rest for 10 minutes before slicing across the grain into slices about ½ inch (1 cm) thick. The required 3-minute safety rest is included within this longer rest, and the pause also makes the meat easier to carve. If the vegetables need more color, return them to the oven while the pork rests. Spoon a little of the pan liquid over the vegetables, taste, and adjust the salt. Scatter with parsley if using, and serve the pork with the roasted vegetables.

Tips

Choose the right cut. Pork loin and pork tenderloin are different cuts. This recipe is written for a broad, boneless loin roast; tenderloin is much narrower and cooks significantly faster, so it should not be substituted using the same timing. Ask a butcher to tie a loose roast if it is uneven, or tie it at 1½-inch (4 cm) intervals with kitchen twine.
Let the pan breathe. Use a pan large enough to keep the vegetables in a mostly single layer. Crowding traps steam and leads to pale, soft vegetables. Two pans are better than a crowded one, but check them separately because pans in different oven positions may brown at different rates.
Use a thermometer, not a time-only rule. Start checking early and place the probe in the thickest section. If one end of the roast is thinner, angle the thermometer so its tip lands in the center of the thick part. A little pink color can remain in pork cooked to the safe temperature; color alone does not confirm doneness.
Swap herbs and vegetables thoughtfully. Use 1 teaspoon (2 g) of dried Italian seasoning in place of the rosemary and thyme, or use parsnips in place of some carrots. Keep vegetable pieces roughly the same size so they cook evenly. Delicate herbs such as parsley are best added after roasting because they can lose their fresh flavor in the oven.

Serving Suggestions

Serve the sliced pork and vegetables straight from a warm platter, with the browned edges of the potatoes and carrots visible and a spoonful of pan juices over the meat. A crisp green salad with a simple vinaigrette makes a bright contrast to the rich roast. Steamed green beans, sautéed cabbage, or roasted Brussels sprouts are also good additions if you want another vegetable on the table.

If you would like a sauce, skim excess fat from the pan liquid and spoon the remaining juices over each serving. For a thicker gravy, move the liquid to a small saucepan, bring it to a simmer, and whisk in a slurry made from 1 teaspoon cornstarch (3 g) mixed with 1 tablespoon cold water (15 ml). Simmer until lightly thickened, then taste before adding salt. Warm dinner rolls or crusty bread are useful for catching any juices left on the plate.

Variations

Change the vegetable mix: Swap up to half the potatoes or carrots for peeled parsnips, chunks of peeled sweet potato, or fennel wedges. Sweet potato tends to soften sooner than regular potatoes, so cut it into larger pieces and check it as the pork cooks. Brussels sprouts can be added for the final 25 to 30 minutes; adding them at the beginning may leave them too soft by the time the loin reaches temperature.

Make it mustard-herb flavored: Stir 1 tablespoon Dijon mustard (15 g) into the oil and herb mixture before rubbing it onto the pork. The mustard brings a gentle tang and helps the seasonings cling, but it will not make the roast taste strongly of mustard. For a more peppery, savory variation, replace the paprika with ½ teaspoon ground cumin (1 g) and add ½ teaspoon fennel seed (1 g), lightly crushed.

Use fresh herbs or broth alternatives: Fresh rosemary and thyme can replace dried herbs as listed in the ingredients; use about three times as much fresh herb by volume. Vegetable broth can stand in for chicken broth, and water works if that is what you have, though it produces a less savory pan liquid. If using salted broth, reduce the added salt slightly and adjust after roasting.

Cook without a roasting pan: A rimmed sheet pan works well as long as it is sturdy enough to hold the roast and its juices. A shallow pan encourages browning; a deep casserole can trap steam around the vegetables. Avoid glass cookware under a broiler or sudden temperature changes, and follow the manufacturer’s instructions for oven use.

Storage and Reheating

Refrigerate cooked pork and vegetables within 2 hours of cooking, dividing large amounts into shallow containers so they cool promptly. Store them covered in the refrigerator for 3 to 4 days. For easier reheating, keep the pork slices and vegetables in separate containers, or place them together with a spoonful of pan juices to limit drying.

Reheat only the portion you plan to eat. In the oven, place pork and vegetables in a covered baking dish with a splash of broth or water and warm at 325°F (165°C) until the leftovers reach 165°F (74°C), checked with a food thermometer. A microwave also works: cover the food, heat in short intervals, and turn or stir the vegetables so the portion warms evenly to 165°F (74°C). The oven usually gives the vegetables a better texture, though reheating takes longer.

For longer storage, freeze the cooked pork and vegetables in airtight freezer-safe containers for about 2 to 3 months for best quality. Thaw overnight in the refrigerator, then reheat to 165°F (74°C). Potatoes may become a little softer after freezing and thawing, but the leftovers remain convenient for another meal.

Frequently Asked Questions

Can I prepare the pork ahead?
Yes. You can mix the oil and seasonings and rub them onto the pork up to a day ahead, then cover and refrigerate it. Keep raw pork refrigerated and set it on the counter only while the oven heats and the vegetables begin roasting; do not leave it at room temperature for an extended period. You can also cut the vegetables ahead and refrigerate them in a covered container, but dry them if they become wet so they roast rather than steam.

Should I sear the pork before roasting?
No searing is necessary for this method. The hot oven browns the seasoned exterior while the roast cooks, and the vegetables develop browned edges on the pan. Searing first can add another layer of color, but it also adds a pan and extra handling; if you choose to sear, do it briefly in an oven-safe skillet, then continue with the recipe and still rely on the thermometer for doneness.

Why did my pork loin turn out dry?
The most common reason is cooking it past the safe temperature, especially if the roast is smaller or thinner than the one in the recipe. Begin checking early, measure the thickest part, and rest the roast before slicing. Cutting with the grain or slicing it too thin can also make each bite seem less tender; cut across the grain and serve with the pan juices.

Can I use bone-in pork loin?
Yes, but the bones can change the shape and cooking time, so use temperature rather than the clock to judge doneness. Keep the vegetables in the pan and begin checking the roast early, then continue roasting as needed until the thickest edible section reaches the safe temperature. Make sure the thermometer tip is in the meat and not touching a bone, which can give a misleading reading.

What if the pork is ready before the vegetables?
Remove the roast to a board, cover it loosely with foil, and let it rest while the vegetables return to the oven for several minutes. Resting the pork for at least 3 minutes after it reaches 145°F (63°C) meets the USDA FSIS guidance for whole cuts; the recipe’s 10-minute rest gives the vegetables extra time if needed. Avoid tightly wrapping the roast, which can soften its browned exterior.

Can I make this recipe with pork tenderloin instead?
The seasoning works with tenderloin, but the timing and pan sequence do not transfer directly. Tenderloin is much smaller and leaner, so it may finish well before the potatoes and carrots. Roast the vegetables until nearly tender first, then add the seasoned tenderloin and check its temperature frequently, removing it as soon as it reaches 145°F (63°C) and giving it a 3-minute rest.
