Easy Pork Roast with Roasted Vegetables: The Best One-Pan Dinner

This easy pork roast with roasted vegetables is a complete one-pan dinner made with a 2 to 2 1/2-pound boneless pork loin, baby potatoes, carrots, and onion. Roast the vegetables first at 425°F, then add the seasoned pork and finish cooking at 375°F until the thickest part reaches 145°F for tender, juicy slices.

The pork is rubbed with garlic, Dijon mustard, rosemary, thyme, salt, and pepper, creating a savory crust while the vegetables roast in the flavorful drippings. With about 15–20 minutes of preparation, 55–75 minutes of roasting, and a 10–15-minute rest, this comforting meal is ready in approximately 1 hour 15 minutes to 1 hour 40 minutes.

Why You’ll Love This Recipe

This pork roast dinner brings the comfort of a traditional Sunday supper to the table with very little cleanup. The pork, potatoes, carrots, and onion all cook in one rimmed pan, so the savory juices mingle with the vegetables as they roast.

The seasoning is simple but full of character. Dijon adds gentle tang, garlic brings savory depth, and rosemary and thyme give the pork a fragrant herb crust without overpowering its mild flavor.

The two-temperature method is especially useful. Starting the vegetables at 425°F gives the potatoes and carrots time to begin tenderizing, while finishing the pork at 375°F helps it cook evenly and remain juicy.

If you enjoy hearty meals built around a seasoned roast, you may also like this garlic and herb pork roast for another comforting dinner idea.

Ingredients You’ll Need

Choose a boneless pork loin roast weighing 2 to 2 1/2 pounds. This cut is wider and larger than pork tenderloin, which is important because the cooking time in this recipe is written for a pork loin roast.

• Pork: One boneless pork loin, patted dry before seasoning.
• Vegetables: Baby potatoes, carrots, and a large yellow onion.
• Seasoning: Olive oil, garlic, Dijon mustard, kosher salt, black pepper, rosemary, and thyme.
• Optional sauce: One-half cup chicken broth for loosening the browned pan drippings.

Cut the potatoes and carrots into similarly sized pieces, roughly 1 1/2 inches thick where possible. Consistent pieces cook at a similar rate, preventing small pieces from burning while larger pieces remain firm.

Fresh herbs work beautifully if you have them, but dried rosemary and thyme are convenient and dependable. Use 1 teaspoon of each dried herb, or 1 tablespoon of each fresh herb.

How to Make It Step-by-Step

Step 1: Heat the oven to 425°F (220°C) and prepare a large rimmed roasting pan or sheet pan. Pat the pork dry with paper towels, since a dry surface helps the mustard-and-herb coating cling to the meat and encourages better browning.

Step 2: In a small bowl, combine 1 tablespoon of the olive oil with the Dijon mustard, minced garlic, about half of the salt and pepper, rosemary, and thyme. Rub the mixture all over the pork, including the sides, so every slice receives a little of the aromatic seasoning.

Step 3: Place the halved baby potatoes, carrot pieces, and onion wedges in the roasting pan. Toss them with the remaining olive oil, salt, and pepper, then spread them out as evenly as possible so hot air can reach the exposed surfaces.

Step 4: Roast the vegetables at 425°F for 20 minutes. This first roasting period gives the potatoes and carrots the head start they need, while the onion begins to soften and develop sweet browned edges.

Step 5: Carefully push the vegetables toward the sides of the pan and set the seasoned pork in the center, fat side up. Reduce the oven temperature to 375°F (190°C), then continue roasting for 35–55 minutes based on the roast’s thickness.

Step 6: Begin checking the pork before the upper end of the time range. Insert an instant-read thermometer into the thickest part, avoiding contact with the pan, and remove the roast as soon as it reaches 145°F (63°C).

Step 7: Transfer the pork to a cutting board and let it rest for 10–15 minutes. Stir the vegetables, and if they need additional color or tenderness, return them to the oven briefly while the pork rests.

Step 8: If you want a quick pan sauce, add the chicken broth to the drippings in the roasting pan and scrape up the flavorful browned bits. Slice the pork across the grain, arrange it with the vegetables, and spoon the warm juices over the top.

How to Get Tender, Juicy Pork

Temperature matters more than the clock. A 2 to 2 1/2-pound pork loin usually needs another 35–55 minutes after the vegetables’ initial roast, but thickness, starting temperature, and individual ovens can change the timing.

Whole cuts of pork should reach a minimum internal temperature of 145°F (63°C), followed by at least a 3-minute rest. A longer 10–15-minute rest is recommended here because it gives the juices time to settle and makes the roast easier to slice.

Try not to substantially overcook the pork. Pork loin is lean, and cooking it far beyond the target temperature can leave the meat dry even when the exterior looks beautifully browned.

Do not swap in pork tenderloin without changing the method and timing. Tenderloin is much smaller and generally cooks in about 20–30 minutes at 425°F, so using the loin timing could overcook it.

Roasting Pan Tips and Variations

Use a pan large enough to hold the vegetables in a fairly open layer. Crowding traps steam and can prevent the potatoes and carrots from developing the roasted edges that make this meal so appealing.

Keep the pork fat side up during roasting. The fat cap helps protect the top of the loin and contributes flavor to the pan juices as it cooks.

• Add a pinch of extra black pepper to the vegetables for a sharper finish.
• Use fresh rosemary and thyme when available for a brighter herbal aroma.
• Let the onion wedges remain fairly large so they do not disappear during roasting.
• If the pork finishes before the vegetables, remove the meat and continue roasting the vegetables until tender.

Serving, Storage, and Reheating

Serve each plate with several slices of pork and a generous spoonful of potatoes, carrots, and onion. The optional broth pan sauce is particularly good drizzled over the meat, where it adds moisture without masking the garlic and herb flavor.

Store cooled leftovers in an airtight container in the refrigerator. Keep the pork and vegetables together or separately, depending on how you plan to reheat them, and use them within a few days for the best texture.

Reheat gently so the lean pork does not dry out. A covered oven-safe dish with a splash of broth works well, while individual portions can be warmed in the microwave in short intervals.

This one-pan format is also a useful companion to roasted chicken and vegetables when you want a similar all-in-one meal with a different protein.

What to Serve with Pork Roast

This dinner is already complete with protein and roasted vegetables, but a crisp green salad can bring freshness to the plate. A simple vinaigrette balances the richness of the pan juices and keeps the meal feeling light.

Warm crusty bread is another practical choice, especially if you make the quick broth sauce. It can be used to catch every last drop of the savory drippings.

For a family meal that ends with something festive, serve a small sweet treat afterward, such as this easy snowman cupcake recipe. If you are comparing simple protein dinners, these crispy pan-fried chicken ideas are another option to keep in your rotation.

Ingredients

  

Main Ingredients

• 1 2 to 2 1/2-pound roast Boneless pork loin roast, not pork tenderloin
• 1 1/2 pounds Baby potatoes, halved
• 1 pound Carrots, peeled and cut into 2-inch pieces
• 1 large Large yellow onion, cut into wedges
• 3 tablespoons Olive oil, divided

Pork Seasoning

• 4 cloves Garlic, minced
• 1 tablespoon Dijon mustard
• 1 1/2 teaspoons Kosher salt, divided
• 1 teaspoon Freshly ground black pepper, divided
• 1 teaspoon or 1 tablespoon Dried rosemary or chopped fresh rosemary
• 1 teaspoon or 1 tablespoon Dried thyme or fresh thyme leaves

Optional Pan Sauce

• 1/2 cup Chicken broth

Method

 

Step-by-Step

1. Heat the oven to 425°F (220°C). Pat the pork loin dry with paper towels so the seasoning adheres well and the exterior browns properly.
2. Mix 1 tablespoon olive oil with the Dijon mustard, minced garlic, about half of the kosher salt and black pepper, rosemary, and thyme. Rub this mixture evenly over every surface of the pork loin.
3. Toss the halved potatoes, carrots, and onion wedges with the remaining olive oil, salt, and pepper. Arrange the vegetables in a large rimmed roasting pan or sheet pan, keeping the pieces in a mostly even layer.
4. Roast the vegetables at 425°F for 20 minutes. This head start helps the denser potatoes and carrots soften before the pork is added.
5. Push the vegetables aside and place the pork in the center of the pan, fat side up. Reduce the oven temperature to 375°F (190°C), then roast for another 35–55 minutes, depending on the thickness of the loin.
6. Check the thickest part of the pork with an instant-read thermometer. Remove it when it reaches 145°F (63°C), then transfer it to a cutting board and rest for 10–15 minutes.
7. Stir the vegetables and return them to the oven briefly if they need more browning while the pork rests. For a quick sauce, add 1/2 cup chicken broth to the pan drippings and stir, scraping up the browned bits.
8. Slice the rested pork across the grain and serve it with the roasted potatoes, carrots, and onion. Spoon a little of the pan sauce over each portion if desired.

Notes

Use an instant-read thermometer rather than relying only on the clock. Whole-cut pork should reach at least 145°F (63°C), followed by at least a 3-minute rest; resting for 10–15 minutes helps retain moisture. Do not substitute pork tenderloin without changing the timing, because it is much smaller and generally cooks in about 20–30 minutes at 425°F.

Final Thoughts

Easy pork roast with roasted vegetables is the kind of dinner that feels special without demanding complicated preparation. The pork develops a fragrant garlic-Dijon crust, while the potatoes, carrots, and onion become tender, browned, and rich with pan-roasted flavor.

For the best result, remember the three essentials: give the vegetables a 20-minute head start, use a thermometer to remove the pork at 145°F, and rest the roast for 10–15 minutes before slicing. Those simple steps make this dependable one-pan dinner juicy, balanced, and ready for both busy weeknights and relaxed family meals.
