Ingredients for boneless pork loin roast recipe with potatoes and carrots
Six ingredients transform into a showstopping Sunday roast with crispy edges and tender meat.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless Pork Loin 🐖 | 2 ½ lb | Center-cut for juiciness, room temperature |
| Baby Potatoes 🥔 | 2 lbs | Halved, skin-on for crispiness |
| Carrots 🥕 | 1 ½ lbs | Whole, scrubbed, trimmed |
| Fresh Rosemary 🌿 | ¼ cup | Finely chopped, stems removed |
| Fresh Thyme 🌿 | 2 tbsp | Leaves only, stems removed |
| Garlic Cloves 🧄 | 6 cloves | Minced for herb crust |
| Olive Oil 🫒 | ⅓ cup | Extra-virgin for richness |
| Dijon Mustard 🍯 | 1 tbsp | For crust adhesion |
| Kosher Salt 🧂 | 2 tbsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | 1 tbsp | Cracked peppercorns preferred |
| Honey 🍯 | 1 tbsp | For caramelizing carrots |
| Fresh Parsley 🌿 | ⅛ cup | Chopped, for garnish |
| Vegetable Oil 🫒 | 1 tbsp | For pan coating |
The pork loin is the star—center-cut for juiciness, not lean cuts that dry out. Grab one from Whole Foods or your local butcher; they'll often trim it for you. Room temperature pork sears better, so take it out of the fridge 1 hour before cooking. For the potatoes, baby potatoes (halved) get crispy faster than large ones. Carrots? Organic is worth it here—they caramelize better without wax. Fresh herbs make all the difference: Trader Joe's has great pre-chopped rosemary and thyme if you're short on time.
No fresh rosemary? Dried works at half the amount, but it lacks that piney aroma. Out of Dijon mustard? Yellow mustard in a pinch, though it's less refined. The honey can be swapped for maple syrup if you're avoiding it. For extra crispy potatoes, toss them in 1 tbsp cornstarch before roasting. The garlic? Pre-minced from a jar is fine—just drain it well. And if you're serving a crowd, double the carrots and potatoes; the pork can handle it too.
Prep ahead like a pro: Make the herb crust the night before and store it in the fridge. The pork and veggies can sit in the pan for up to 4 hours before roasting—just cover and refrigerate. Leftovers? 3-4 days in the fridge, or freeze for 3 months. I always save the pan juices—reduce them with a splash of broth for a quick gravy. The pork reheats beautifully sliced thin; the potatoes and carrots? Microwave with a damp paper towel for 30 seconds to revive crispiness.

Step-by-step instructions for herb-crusted pork roast with potatoes and carrots
This one-pan wonder delivers a showstopping centerpiece with minimal cleanup.
👨🍳 Step 1: Prep the Pork and Vegetables for Perfect Roasting
Start by preheating your oven to 400°F. While it heats, take the 2.5 lb boneless pork loin and pat it completely dry with paper towels—this is non-negotiable for crispy crust. In a small bowl, mix together 0.33 cup olive oil, 1 tbsp Dijon mustard, 2 tbsp kosher salt, 1 tbsp freshly ground black pepper, and 6 minced garlic cloves. Rub this mixture all over the pork, pressing firmly so it adheres.
Next, chop 0.25 cup fresh rosemary and 2 tbsp fresh thyme and sprinkle half of each over the pork. Save the rest for the vegetables. Halve the 2 lbs baby potatoes (leave skins on for texture) and scrub the 1.5 lbs carrots clean. Toss everything with the remaining rosemary, thyme, 1 tbsp honey, and a drizzle of olive oil. Here's the thing—don't skip the honey on the carrots. It caramelizes beautifully during roasting, adding natural sweetness that balances the savory pork.
🍳 Step 2: Sear the Pork for Maximum Flavor
Heat 1 tbsp vegetable oil in a large oven-safe skillet over medium-high heat until shimmering. Place the pork loin in the pan and sear for 3-4 minutes per side until golden brown. You're not cooking it through here—just creating that gorgeous crust that'll lock in juices later. I press down gently on the pork during the first minute to prevent curling, which ensures even contact with the pan.
Once browned, remove the pork and set it aside. In the same pan, add the potatoes and carrots in a single layer, spreading them out so they have room to crisp. Don't crowd the pan—this prevents steaming and ensures crispy edges. Roast uncovered for 20 minutes at 400°F to start par-cooking the vegetables while you finish the pork.
🥘 Step 3: Build the Herb Crust and Roast to Perfection
After the initial 20 minutes, return the pork to the skillet and spoon any accumulated pan juices over the top. Sprinkle the remaining 0.125 cup chopped fresh parsley over everything. Here's where the magic happens: cover the skillet tightly with foil and transfer to the oven. This traps steam and helps the pork cook through evenly while the vegetables finish roasting.
Reduce heat to 325°F and roast for another 45-50 minutes until the pork reaches 145°F internally. You'll know it's done when the meat is fork-tender with just a hint of resistance in the center. The potatoes should be fork-tender with crispy edges, and the carrots should be tender with caramelized tops from the honey. Real talk: your oven might run hot, so start checking at the 40-minute mark if you're unsure.
⏰ Step 4: Rest and Garnish for Showstopping Presentation
Remove the pork from the oven and let it rest on a cutting board for 10-15 minutes before slicing. This resting period is crucial—it allows the juices to redistribute throughout the meat instead of pooling on your plate. While it rests, use a slotted spoon to transfer the potatoes and carrots to a serving platter. Spoon any pan juices over the vegetables and sprinkle with additional chopped parsley for freshness.
Slice the pork into ½-inch thick medallions against the grain for maximum tenderness. Arrange the slices over the vegetables and drizzle any remaining pan juices over the top. The result should be golden, herb-infused pork with perfectly caramelized carrots and crispy baby potatoes—everything you'd expect from a Sunday feast without the fuss. Serve immediately while the pork is still juicy and the vegetables are warm.
Pro Tips For Making Boneless Pork Loin Roast Recipe With Potatoes And Carrots
- Sear the Pork First: Hit the pork loin with a screaming-hot pan—no oil needed, just the natural fat—until deep brown crust forms. I learned this the hard way: skipping the sear means a bland, gray slab instead of juicy, flavor-packed meat that’ll hold up to roasting.
- Parboil Potatoes Roughly: Toss baby potatoes in boiling water for 8–10 minutes until just fork-tender, not mushy. Overcooking turns them to mush; undercooking means they’ll stay raw inside. Drain well—wet potatoes steam instead of crisp up.
- Don’t Overcrowd the Pan: When searing carrots after the pork, work in batches if needed. Crowding steams them instead of caramelizing, and you’ll end up with sad, pale sticks instead of deep golden, sweet edges. Patience here makes a real difference.
- Use Butter for Herbs: Toss the drained potatoes and carrots with 2 tablespoons melted butter, then sprinkle in chopped rosemary and thyme. The fat clings to the herbs, releasing their aroma as they roast—way better than just sprinkling dry. (Yes, even if you’re impatient like me.)
Dietary considerations for boneless pork loin roast recipe with potatoes and carrots
Gluten-Free Adaptations
This recipe is naturally gluten-free, but I always double-check labels on ingredients like Dijon mustard and honey—some brands add gluten as a thickener. I recommend Annie's Organic mustard or Bragg's for certified gluten-free options.
The herb crust and vegetables stay completely gluten-free as long as you avoid cross-contamination with shared utensils or pans. 🌱
Low-Carb Version
For a lower-carb option, swap the baby potatoes for cauliflower florets (tossed in the same herb-oil mix) or zucchini slices. The carrots can stay—their natural sweetness enhances the dish without overpowering.
Just reduce the honey to ½ tbsp to balance flavors. I've tested this version with my daughter Lily (who loves veggies) and it's a hit!
Dairy-Free Considerations
This recipe is already dairy-free, but if you're using pre-chopped herbs from a jar, check for butter or whey additives. The Dijon mustard and honey are naturally dairy-free, and the olive oil provides richness without dairy.
For extra crispiness on the potatoes, I sometimes add 1 tbsp nutritional yeast to the herb mix—it adds a cheesy flavor without any dairy. 🥔
Allergen-Friendly Swaps
For nut allergies, ensure your olive oil is refined (some brands process with nuts). If you're avoiding honey, maple syrup works perfectly in the vegetable mix. For soy allergies, check your vegetable oil—avocado oil is a great alternative.
I always keep these swaps handy in my Portland kitchen, especially when hosting friends with dietary restrictions.
Protein-Packed Boost
Want extra protein? Add ½ cup cooked quinoa to the vegetable mix before roasting, or sprinkle ¼ cup crumbled feta cheese (if dairy isn't an issue) over the pork before the final roast.
I've also tested this with chickpeas for a vegetarian twist—they absorb the herb flavors beautifully. The pork already provides 40g protein per serving, so these additions make it a powerhouse meal. 💪
Keto-Friendly Adjustments
For a keto version, eliminate the potatoes entirely and use radishes or asparagus instead. The carrots can stay in moderation (about ½ lb total), and the pork remains the star. Boost the fat content by adding 1 tbsp butter to the herb crust.
I've found that 1 tbsp erythritol mixed with the honey on the carrots gives that caramelized sweetness without carbs. The result is a satisfying, low-carb feast that still feels indulgent. 🥕
Nutrition facts
Frequently asked questions
How do I keep the pork loin juicy and avoid drying it out?
Pat the pork completely dry before seasoning—this helps create a crispy crust that locks in juices. Use a meat thermometer to check for 145°F internal temperature (not 160°F), and let it rest for 10-15 minutes before slicing. Room-temperature pork sears better, so take it out of the fridge 1 hour before cooking.
Can I use regular potatoes instead of baby potatoes?
Yes, but you'll need to cut them into 1-inch chunks and increase roasting time by 5-10 minutes. Baby potatoes cook faster and get crispier because their skins are thinner. For even cooking, parboil regular potatoes for 5 minutes before roasting if you're short on time.
What's the best way to caramelize the carrots without burning them?
The honey is key! Toss carrots with 1 tbsp honey and roast at 400°F for 20 minutes uncovered, then reduce heat to 325°F for the final 45 minutes. For extra color, broil for 2-3 minutes at the very end. Avoid overcrowding—they need space to caramelize evenly.
How do I adjust this recipe for a larger crowd?
Double the pork (use a 5 lb loin) and increase potatoes/carrots by 50%. Use two roasting pans if needed, and add 10-15 minutes to the cook time. For presentation, arrange slices on a platter with extra herbs and pan juices—it'll look just as impressive!
Can I make this ahead of time?
Assemble the pork and vegetables in the pan up to 4 hours ahead, cover, and refrigerate. Add 10-15 minutes to cook time when roasting from cold. For leftovers, store in an airtight container for 3-4 days—reheat pork slices in a skillet with a splash of broth to revive moisture.
