Ingredients for Pork Loin Roast Recipe with Potatoes and Carrots
A boneless pork loin with potatoes and carrots roasted together for a complete oven-baked meal.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Loin Roast 🥩 | 2 lb | Boneless, center-cut preferred |
| Yukon Gold Potatoes 🥔 | 1 ½ lb | Cut into 1.5-inch chunks |
| Carrots 🥕 | 4 whole | Peeled, cut into 2-inch pieces |
| Olive Oil 🫒 | 3 tbsp | Divided for roast and vegetables |
| Kosher Salt 🧂 | 2 tsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | 1 tsp | Coarse grind recommended |
| Garlic Cloves 🧄 | 4 cloves | Minced for rub |
| Dried Rosemary 🌿 | 1 tbsp | Crushed between fingers |
| Dried Thyme 🍃 | 1 tsp | Rubbed to release oils |
| Dijon Mustard 🟡 | 2 tbsp | For herb marinade base |
| Chicken Broth 🥣 | ½ cup | Low-sodium preferred |
| Unsalted Butter 🧈 | 2 tbsp | Melted, for basting |
The pork loin is the centerpiece—opt for center-cut boneless roast with even marbling for consistent cooking. Whole Foods or Costco offer quality options; ask the butcher to trim excess fat if needed. Yukon Gold potatoes provide the perfect creamy yet sturdy texture for roasting. For carrots, select firm, vibrant orange specimens without cracks.
No Yukon Golds? Russet potatoes work but may dry out slightly more. Swap fresh rosemary and thyme if available (one-third the amount for fresh). Dijon can be replaced with whole-grain mustard for texture. For a richer pan sauce, substitute beef broth for chicken. The butter can be omitted, though it adds depth to the vegetables.
Store raw pork in its packaging on a plate in the coldest part of the fridge for up to 3 days. Potatoes and carrots keep separately for 1-2 weeks in a cool, dark place. Leftovers maintain quality for 4-5 days refrigerated or freeze for 3 months.

Step-by-Step Instructions for Pork Loin Roast With Potatoes And Carrots
This method ensures perfectly roasted meat with tender vegetables every time.
Step 1: Prepare the Herb Marinade for the Pork
In a small bowl, combine the 2 tbsp Dijon mustard, 1 tbsp dried rosemary, 1 tsp dried thyme, and 2 tsp kosher salt. I crush the rosemary between my fingers as I add it to release its aromatic oils. Add the 4 cloves garlic cloves, minced, and 1 tsp freshly ground black pepper.
Rub this mixture evenly over the entire surface of the 2 lb pork loin roast. The mustard helps the herbs adhere while creating a flavorful crust. Let the pork sit at room temperature for 20 minutes while you prepare the vegetables this allows the flavors to penetrate the meat more deeply.
Step 2: Prepare the Vegetables for Roasting
Cut the 1.5 lb Yukon Gold potatoes into 1.5-inch chunks and the 4 whole carrots into 2-inch pieces. Place them in a large bowl and drizzle with 2 tbsp olive oil of the 3 tbsp olive oil. Toss to coat evenly.
Sprinkle with a pinch of the remaining kosher salt and freshly ground black pepper. The oil helps the seasoning stick and promotes even browning. Set aside while you sear the pork.
Step 3: Sear the Pork and Begin Roasting
Preheat your oven to 425°F. Heat the remaining 1 tbsp olive oil in a large oven-safe skillet or Dutch oven over medium-high heat. Sear the pork loin on all sides for 2-3 minutes per side until deeply browned. This creates a flavorful crust and locks in juices.
Transfer the seared pork to a plate and add the 0.5 cup chicken broth to the hot pan, scraping up any browned bits. These bits contain concentrated flavor that will enhance your roast and vegetables.
Step 4: Roast the Pork with Vegetables
Return the pork to the skillet and arrange the prepared potatoes and carrots around it. Pour any accumulated juices from the pork plate over the top. Place the skillet in the preheated oven and roast for 25 minutes.
After 25 minutes, reduce the oven temperature to 375°F and baste the pork with the 2 tbsp unsalted butter, melted. Continue roasting for another 25-30 minutes or until the pork reaches an internal temperature of 145°F and the vegetables are fork-tender.
Step 5: Rest and Serve
Transfer the pork to a cutting board and tent loosely with foil. Let it rest for 10 minutes this allows the juices to redistribute throughout the meat. The internal temperature will rise by about 5°F during this time.
Slice the pork into ½-inch thick pieces and arrange on a platter with the roasted potatoes and carrots. Spoon any pan juices over the top. The pork should be juicy with a lightly pink center, while the vegetables should be golden and caramelized at the edges.
Pro Tips For Making Pork Loin Roast Recipe With Potatoes And Carrots
- Sear First, Roast Later: I learned this the hard way—searing the pork loin in a hot pan with olive oil before roasting locks in juices and gives that golden crust. Skip this and you’ll miss out on depth of flavor.
- Cut Potatoes Evenly: Yukon Golds cook unevenly if left whole or chopped haphazardly. Aim for 1.5-inch chunks so they soften at the same rate as the carrots and finish with the pork.
- Don’t Crowd the Pan: After burning three batches, I finally figured out that spreading potatoes and carrots in a single layer ensures they roast, not steam. Pile them up and you’ll get soggy veggies.
- Rest Before Slicing: Give the pork loin a solid 10 minutes under foil after roasting. Sounds weird, but it works—the juices redistribute, and you won’t lose half of them on the cutting board.
Make-Ahead Tips for This pork loin roast recipe with potatoes and carrots
Prep Ahead Strategy
You can prep the herb marinade and chop all vegetables up to 12 hours in advance. Store the seasoned pork and cut veggies separately in the fridge—I use glass containers to avoid plastic odors. This makes the morning-of cooking seamless. 💡
Marinating Overnight
For deeper flavor, rub the pork with the herb-Dijon mixture and let it marinate overnight. The acids in mustard tenderize the meat while herbs infuse. Just take it out 30 minutes before cooking to bring to room temperature.
Partial Cooking Method
If you’re really pressed for time, sear the pork and par-roast it at 325°F for 20 minutes the night before. Refrigerate, then finish cooking with vegetables the next day. This head start cuts active time in half.
Vegetable Prep
Potatoes and carrots can be peeled and cut the day before. Submerge in cold water to prevent browning—I change the water once if storing longer than 8 hours. Drain and pat dry before using.
Reheating Leftovers
This dish reheats beautifully. Cover slices with foil and warm at 350°F for 10-12 minutes. Add a splash of broth to keep the pork moist. The vegetables actually taste better the next day.
Freezing Tips
Cool completely, then freeze pork and vegetables separately in airtight containers for up to 3 months. Thaw overnight in the fridge before reheating. The texture stays remarkably good for meal prep. ❄️

Frequently Asked Questions
How do I know when the pork is done?
Use a meat thermometer to check the internal temperature. It should read 145°F in the thickest part. The pork will continue cooking while resting, reaching 150°F after 10 minutes.
Can I use different vegetables?
Try parsnips, sweet potatoes, or Brussels sprouts. Cut them into similar sizes for even cooking. Stick to root vegetables that can handle 45-60 minutes of roasting.
Why does my pork come out dry?
Overcooking is the main cause. Pull it from the oven at 145°F and let it rest. Also, avoid skipping the searing step—it helps retain juices. Resting is crucial for moisture redistribution.
Can I make this in a slow cooker?
For a slow cooker, sear the pork first, then cook on low for 6-7 hours. Add vegetables in the last 2-3 hours to prevent overcooking. The texture will differ but remain flavorful.
