There’s something deeply satisfying about a perfectly cooked pork loin roast with potatoes and carrots, all infused with fresh herbs. This one-pan meal transforms simple ingredients into a Sunday dinner masterpiece with minimal effort and maximum flavor.
I developed this recipe after years of testing different herb combinations and roasting techniques. The key is searing the pork first to lock in juices, then letting everything cook together so the vegetables absorb all those rich, meaty flavors.
What emerges from the oven is tender pork with a golden crust, surrounded by caramelized potatoes and carrots that have soaked up every bit of the herb-infused pan juices. It’s the kind of meal that brings everyone to the table.
Serve straight from the pan for an impressive yet unfussy presentation.
Ingredients for Pork Loin Roast Recipe with Potatoes and Carrots
A handful of quality ingredients transforms into a Sunday dinner centerpiece with ease.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Loin Roast 🥩 | 2 lb | Boneless, center-cut preferred |
| Yukon Gold Potatoes 🥔 | 1 ½ lb | Peeled and quartered |
| Carrots 🥕 | 4 whole | Peeled and cut into chunks |
| Fresh Rosemary 🌿 | 2 tbsp | Finely chopped |
| Fresh Thyme 🍃 | 2 tbsp | Leaves stripped from stems |
| Garlic Cloves 🧄 | 6 cloves | Minced for maximum flavor |
| Olive Oil 🫒 | 3 tbsp | Divided for searing and roasting |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | 1 tsp | Freshly ground for best results |
| Dijon Mustard 🟡 | 1 tbsp | For crust and flavor enhancement |
| Chicken Stock 🍲 | ½ cup | Low-sodium for controlled seasoning |
| Unsalted Butter 🧈 | 2 tbsp | For basting the pork |
The pork loin is the foundation—look for center-cut roasts with even marbling at Whole Foods or your trusted butcher. Yukon Gold potatoes add creaminess, while carrots provide natural sweetness. Fresh herbs are non-negotiable; sourced from farmers markets when possible, they deliver the vibrant flavor that dried simply can’t match. The garlic should be plump and firm, not sprouting.
No fresh rosemary or thyme? Dried herbs at one-third the amount work in a pinch, though the flavor won’t be as bright. Out of Dijon? Whole-grain mustard adds a nice texture. Chicken stock can be swapped for vegetable stock without issue. For the butter, ghee or olive oil can stand in, though the richness will differ slightly.
Store the pork in the coldest part of your fridge for up to 3 days before cooking. Potatoes and carrots keep well in a cool, dark place for 2 weeks. Fresh herbs should be wrapped in damp paper towels and used within 5 days for peak flavor.

Step-by-Step Instructions for Pork Loin Roast With Potatoes And Carrots
This one-pan method ensures perfectly cooked pork with tender vegetables and minimal cleanup.
Step 1: Prepare the Herb Rub and Sear the Pork
In a small bowl, combine the 2 tbsp Fresh Rosemary, 2 tbsp Fresh Thyme, 6 cloves Garlic Cloves, 1.5 tsp Kosher Salt, 1 tsp Black Pepper, and 1 tbsp Dijon Mustard with 1 tbsp Olive Oil. Rub this mixture all over the 2 lb Pork Loin Roast, pressing it into the meat to create a flavorful crust.
Heat 1 tbsp Olive Oil in a large oven-safe skillet over medium-high heat. Sear the pork on all sides until deep golden brown, about 3-4 minutes per side. This creates a rich fond in the pan that will enhance the final dish.
Step 2: Add Vegetables and Deglaze the Pan
Remove the pork from the skillet and set it aside. In the same pan, add the 1.5 lb Yukon Gold Potatoes and 4 whole Carrots, tossing them in the remaining oil and pork drippings. Arrange them in a single layer around the edges of the skillet.
Pour in the 0.5 cup Chicken Stock to deglaze the pan, scraping up any browned bits with a wooden spoon. This step infuses the vegetables with flavor while preventing them from sticking to the pan.
Step 3: Roast Until Pork Reaches Temperature
Return the pork to the center of the skillet, placing it on top of the vegetables. Transfer the skillet to a preheated 375°F oven. Roast for 30-40 minutes, or until the pork reaches an internal temperature of 145°F.
The vegetables should be fork-tender and lightly caramelized. If they begin to dry out, add a splash of water or additional Chicken Stock to the pan.
Step 4: Rest and Finish with Butter
Remove the skillet from the oven and transfer the pork to a cutting board. Tent it loosely with foil and let it rest for 10 minutes. During this time, stir the 2 tbsp Unsalted Butter into the vegetables in the skillet, allowing it to melt and create a glossy, flavorful coating.
Slice the pork into ½-inch thick medallions and serve it alongside the roasted Yukon Gold Potatoes and Carrots. Spoon any pan juices over the top for added moisture and flavor.
Pro Tips For Making Pork Loin Roast Recipe With Potatoes And Carrots
- Sear the Pork First: Crank the heat to medium-high and sear the pork loin on all sides until golden brown—about 3-4 minutes per side. I learned this the hard way: skipping this step leaves the roast pale and the flavors flat, even with herbs. —
- Cut Potatoes Evenly: Slice the Yukon Golds into 1.5-inch chunks so they cook at the same rate as the carrots. Sounds fussy, but nothing ruins a meal faster than half-burnt, half-raw potatoes. —
- Use a Meat Thermometer: Pull the pork at 145°F internal temperature—it’ll rise to 150°F while resting. After overcooking my first three roasts, I finally bought one and now the meat stays juicy every time. —
- Toss Veggies in Drippings: After removing the pork, toss the potatoes and carrots in the pan juices before roasting. It’s the easiest way to add depth without extra effort—I do this even when I’m in a rush.
Health Benefits of These Flavors
Protein Powerhouse
This dish delivers 48 grams of protein per serving from the pork loin alone, making it an excellent choice for muscle maintenance and growth. I love how lean pork provides high-quality protein without excessive saturated fat. 💪
Vitamin Rich Vegetables
The Yukon Gold potatoes contribute 45% of your daily vitamin C needs, while the carrots provide over 300% of vitamin A in a single serving. These nutrients support immune function and eye health beautifully.
B Vitamin Boost
Pork is one of the best sources of vitamin B6 and B12, essential for energy metabolism and nervous system health. A 6-ounce serving provides nearly 50% of your daily B12 needs.
Iron and Zinc
The pork in this meal supplies heme iron, which your body absorbs more easily than plant-based iron. Combined with the zinc from both pork and potatoes, this helps maintain healthy red blood cells and immune function.
Antioxidant Properties
Carrots contain beta-carotene, a powerful antioxidant that gives them their vibrant color. The rosemary and thyme in this recipe also provide rosmarinic acid and thymol, compounds with antioxidant benefits. ✨
Low Sodium Option
By controlling the salt content yourself, you can keep this meal heart-healthy. The recipe uses just 1.5 tsp Kosher Salt for the entire dish, making it suitable for those watching their sodium intake.
Nutrition Facts
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 juices should run clear, not pink.
Can I use baby potatoes instead?
Yes! Halve baby potatoes and roast them alongside the pork. They’ll cook in about the same 30-40 minutes at 375°F.
Why rest the pork before slicing?
Resting for 10 minutes lets juices redistribute. Skipping this step can make the meat dry as all the moisture escapes when cut.
What if my vegetables aren’t tender?
If they’re still firm after roasting, return the pan to the oven for 5-10 minutes. Add a splash of chicken stock to prevent drying.
