Pork Tenderloin with Carrots and Potatoes Recipe: One-Pan Roast with Crispy Potatoes and Sweet Carrots

This one-pan pork tenderloin recipe delivers restaurant-quality dinner in under an hour with minimal cleanup. 💛 The secret lies in perfectly tender pork paired with crispy potatoes and sweet, caramelized carrots—all roasted together for balanced flavors and effortless harmony.

I developed this after years of testing one-pan meals that actually work, not just sound impressive.

The pork tenderloin stays juicy thanks to a simple herb marinade while the potatoes develop crispy edges and fluffy centers. Carrots caramelize beautifully, adding natural sweetness that complements the savory pork.

This method transforms weeknight dinners into special meals without requiring fancy techniques—just one pan, precise timing, and attention to doneness.

What you'll achieve is a complete meal with tender pork that falls apart easily, golden potatoes with crispy skins, and carrots that are sweet yet still hold their texture.

The aromas alone will have everyone gathered at your table, and the flavors balance perfectly for a satisfying, hearty dinner that feels like a home-cooked masterpiece.

Serve with a simple green salad or crusty bread to soak up the juices. The recipe scales beautifully for families or gatherings, and leftovers reheat wonderfully. Here's how to make it perfectly every time, with tips to ensure crispy potatoes and tender pork without fail.

Ingredients for pork tenderloin recipe with carrots and potatoes

Restaurant-quality pork tenderloin, crispy potatoes, and caramelized carrots—all roasted together in one pan for effortless harmony.

The pork tenderloin is the star, so choose a center-cut piece—it stays juicier and cooks more evenly. Costco or local butchers often carry the best quality, but your grocery store's fresh meat section works too. Look for a piece with good marbling and vibrant color. Baby potatoes and carrots roast more evenly than larger cuts, but if you only have standard sizes, cut them into even pieces. Organic produce holds up better during roasting, but conventional works fine. The key to crispy potatoes lies in their size—halving them ensures even cooking without burning.

No fresh rosemary? Dried works at one-third the amount, but fresh delivers that bright, piney aroma. Substitute thyme with oregano if needed, though rosemary's earthy notes are ideal here. For the honey glaze, agave nectar works in a pinch, though honey adds subtle depth. The balsamic vinegar can be swapped for red wine vinegar, but balsamic's caramelized sweetness is perfect. If you're short on time, pre-minced garlic from a jar is fine—just drain it well to avoid excess moisture in your marinade. The parsley is purely decorative, so skip it if you're out, but it adds a fresh pop of color.

Roasted pork tenderloin reheats beautifully—just warm in the oven at 350°F for 10-15 minutes to restore crispiness. Store leftovers in an airtight container for up to 4 days, though the potatoes and carrots soften over time. For best texture, reheat potatoes and carrots separately in a skillet with a splash of water. The marinade keeps for 3 days in the fridge, so make extra for another use. Portion the pork into individual servings before freezing for up to 3 months—it thaws beautifully in the fridge overnight.

Step-by-step instructions for pork tenderloin with carrots and potatoes

Master this one-pan technique for perfectly crispy potatoes and tender pork with caramelized carrots.

Pat the 1.5 lb pork tenderloin dry with paper towels—this ensures maximum crispiness. In a small bowl, whisk together 0.5 cup extra-virgin olive oil, 1 tbsp honey, 1 tbsp balsamic vinegar, 1.5 tsp diamond crystal kosher salt, 1 tsp freshly ground black pepper, 0.25 cup chopped fresh rosemary, 0.25 cup chopped fresh thyme, and 4 minced garlic cloves. Rub this marinade all over the pork, pressing it into every crevice. Let it sit at room temperature for 15 minutes while you prep the vegetables.

I like to use a plastic wrap twist to secure the marinade—wrap the pork loosely and refrigerate for 30 minutes if time allows. This step develops deeper flavor and ensures even cooking. The honey-balsamic glaze will create a beautiful caramelized crust during roasting.

Scrub the 1.5 lb carrots thoroughly under cold water to remove dirt, leaving them whole. Halve the 1.5 lb baby potatoes lengthwise—no need to peel them, as the skins add texture. Toss both vegetables in a large bowl with 1 tbsp olive oil, 0.5 tsp kosher salt, and a pinch of black pepper. Arrange them cut-side down on a parchment-lined baking sheet.

Here's the thing—don't overcrowd the pan. Spread the vegetables in a single layer with slight gaps between them. This allows hot air to circulate and creates those coveted crispy edges. I arrange the potatoes and carrots in concentric circles around the pork for even heat distribution.

Preheat your oven to 425°F. Place the marinated pork tenderloin in the center of the baking sheet, surrounded by the potatoes and carrots. Roast for 25 minutes, then carefully flip the potatoes and carrots using a metal spatula. Return to the oven and roast for another 15 minutes until the potatoes are golden brown and the carrots begin to soften.

After 40 minutes total, check the pork's internal temperature with a meat thermometer—it should read 145°F. If it's not quite there, return to the oven for 5-10 minutes more. The potatoes should be deep golden brown with crispy edges, and the carrots should be tender with slightly caramelized edges. Don't walk away during this final phase—ovens vary, and you want that perfect doneness.

Remove the pork from the oven and transfer it to a cutting board. Tent loosely with foil to keep warm. In the same baking sheet, increase oven temperature to broil. Pour the accumulated pan juices into a small saucepan and simmer over medium heat for 2-3 minutes until slightly reduced. Stir in 1 tsp honey and 1 tsp balsamic vinegar to create a glossy glaze.

Brush this glaze generously over the pork, then return it to the broiler for 2-3 minutes until caramelized. Watch carefully—broilers can work fast, and you want a beautiful color without burning. The potatoes and carrots can stay in the oven during this final step to maintain their heat.

Transfer the pork to a serving platter and arrange the crispy potatoes and tender carrots around it. Sprinkle with 0.25 cup chopped fresh parsley for a pop of color and freshness. Let everything rest for 5 minutes before serving—this allows the juices to redistribute in the pork for maximum tenderness.

The result should be a perfectly tender pork tenderloin with a caramelized glaze, crispy baby potatoes, and sweet caramelized carrots. Each bite delivers a balance of textures and flavors that makes this one-pan roast a weeknight staple. Serve with a simple green salad to complete the meal.

Essential equipment for great pork tenderloin recipe with carrots and potatoes

Must-Have Pan

You'll need a rimmed baking sheet with sides at least 1 inch tall—I recommend a half-sheet pan (18x13 inches) for even heat distribution. All-Clad Hard-Anodized or Calphalon pans handle high heat without warping.

For budget-friendly options, Costco's stainless steel sheet pans work perfectly. Avoid non-stick pans—they can't handle the high 425°F temperature needed for crispy potatoes. 🔥

Precision Tools

A meat thermometer is non-negotiable for perfect pork—Thermoworks Smoke or Taylor Precision models are my favorites. They're fast, accurate, and built to last. For flipping potatoes and carrots, use a metal spatula (I love OXO Good Grips)—it's sturdy enough to handle hot pans without bending.

A sharp chef's knife (like Mercer Culinary) is essential for prepping veggies efficiently.

Oven Essentials

Invest in parchment paper—I use Reynolds Non-Stick Parchment—to line your pan for easy cleanup and even browning. A wire cooling rack helps maintain crispiness after roasting.

For the broiling step, I keep a heat-resistant glove nearby to protect my hands from the intense heat. Oven mitts are a must when handling hot pans and baking sheets.

Marinade Mixers

Use a small mixing bowl (like Pyrex glass bowls) for your marinade—it's easy to whisk and measure. A microplane (I prefer Microplane Zester) quickly minces garlic and zest for fresh flavor.

For herbs, a herb scissors (like Victorinox) gives you clean, precise cuts. A measuring spoons set ensures accurate honey and vinegar ratios in your glaze.

Optional Upgrades

For extra crispiness, a pork tenderloin rack (like Norpro) elevates the meat for even cooking. A digital kitchen scale (I use OXO Good Grips) helps measure ingredients precisely.

For presentation, I like ceramic serving dishes (like Le Creuset) to keep food warm while plating. These upgrades aren't essential but elevate the final result to restaurant quality. 💫
