Ingredients for turkey breast and sweet potato
Sixteen ingredients, two techniques, one showstopping holiday meal.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless Turkey Breast 🦃 | 2 ½ lb | Freshly trimmed, skin-on preferred |
| Large Sweet Potatoes 🍠 | 3 whole | Organic if possible, uniform size |
| Fresh Rosemary 🌿 | ¼ cup | Chopped, stems removed |
| Fresh Thyme 🌿 | ¼ cup | Leaves only, finely chopped |
| Garlic Cloves 🧄 | 6 cloves | Peeled, minced |
| Extra-Virgin Olive Oil 🫒 | ½ cup | High-quality, fruity |
| Brown Sugar 🍚 | ¼ cup | Light or dark, packed |
| Kosher Salt 🧂 | 2 tbsp | Diamond Crystal preferred |
| Ground Black Pepper 🌶️ | 1 tbsp | Freshly cracked |
| Ground Cinnamon 🌶️ | 1 tsp | Freshly toasted |
| Ground Nutmeg 🌶️ | ½ tsp | Freshly grated |
| Fresh Lemon Juice 🍋 | 2 tbsp | From organic lemons |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed |
| Vegetable Broth 💧 | 1 ½ cups | Low-sodium preferred |

The turkey breast is non-negotiable here—look for a piece with good marbling and uniform thickness for even cooking. Costco or Whole Foods usually have excellent quality, but your local butcher can trim it perfectly if you ask. Fresh herbs make all the difference: Trader Joe's sells pre-chopped rosemary and thyme, but I always grab whole sprigs and chop them myself. The sweet potatoes should be firm with no soft spots—organic varieties like Beauregard hold up best to roasting. For the brown sugar, muscovado adds depth if you want to splurge, but regular light brown works perfectly fine.
No fresh rosemary? Dried works at half the amount, but it lacks that piney aroma. Short on thyme? Oregano or marjoram can stand in, though the flavor will differ slightly. Want to skip the pecans? Toasted walnuts or candied pumpkin seeds add a similar crunch. The vegetable broth can be swapped for apple cider or white wine if you're making gravy separately. For the turkey brine, use a 1:4 ratio of salt to water—so 1 cup salt to 4 cups water—and let it soak for at least 2 hours (overnight is ideal). Don't skip this step—it's what makes the turkey truly tender.
The turkey keeps best in the fridge for 2 days if wrapped tightly in foil, but honestly, it reheats beautifully—just warm in a 325°F oven with a splash of broth. Sweet potatoes reheat well too, though they're best eaten fresh out of the oven. For make-ahead prep, peel and cube the potatoes up to 2 days ahead, store in an airtight container, and toss with olive oil and spices right before roasting. The herbs? Store them in damp paper towels in a sealed bag for up to 5 days. This meal tastes even better the next day—perfect for Thanksgiving leftovers that actually get rave reviews.

Step-by-step instructions for herb-roasted turkey breast with caramelized sweet potatoes
Here's how to create a perfectly balanced dish where tender turkey meets sweet, spiced potatoes.
Prepare the Turkey and Sweet Potatoes with Herb Rub
Pat the 2.5 lb boneless turkey breast completely dry with paper towels—this ensures crispy skin. In a small bowl, combine 0.25 cup chopped fresh rosemary, 0.25 cup chopped fresh thyme, 1 tbsp ground black pepper, 1 tsp ground cinnamon, and 0.5 tsp ground nutmeg. Rub this mixture all over the turkey, pressing firmly so the spices adhere. Let it sit at room temperature for 30 minutes.
While the turkey rests, scrub and dry the 3 whole large sweet potatoes. Prick each potato 4-5 times with a fork to prevent bursting. In a separate bowl, whisk together 0.5 cup extra-virgin olive oil, 0.25 cup packed brown sugar, 2 tbsp kosher salt, and 2 tbsp fresh lemon juice. Brush this mixture generously over the sweet potatoes, coating them evenly. Let them sit while you preheat the oven.
Roast the Turkey Until Juicy Perfection
Preheat your oven to 375°F. Place the seasoned turkey breast on a rack set inside a roasting pan, with the fat side up if your turkey has skin. Roast for 1 hour 15 minutes until the internal temperature reaches 160°F when measured at the thickest part. The skin should be golden brown and crispy, while the meat remains juicy.
Here's the thing—don't overcook the turkey. It'll continue cooking slightly as it rests, and you want it tender, not dry. If the skin browns too quickly, tent it loosely with foil for the last 15 minutes of cooking. Remove the turkey from the oven and let it rest for 15 minutes before slicing—this allows the juices to redistribute throughout the meat.
Roast the Sweet Potatoes Until Caramelized
While the turkey rests, place the prepared sweet potatoes directly on the oven rack (no pan needed) and return them to the oven at 375°F. Roast for 45-50 minutes, turning them occasionally, until their skin is deeply caramelized and they yield slightly to pressure. The potatoes should be tender inside with a crispy exterior—this is where the magic happens.
About 10 minutes before the potatoes are done, add 0.5 cup cubed unsalted butter and 1.5 cups vegetable broth to the roasting pan. Scrape up any browned bits from the bottom of the oven with a wooden spoon—these contain concentrated flavor. Pour this mixture over the potatoes and return them to the oven to steam slightly, creating a glossy, caramelized glaze.
Slice and Serve with Toasted Pecans
Slice the rested turkey breast into ¼-inch thick pieces against the grain for maximum tenderness. Arrange the slices on a platter alongside the caramelized sweet potatoes. The potatoes should be fork-tender with a sticky, sweet glaze—if they're not quite glazed enough, return them to the oven for another 5 minutes with a splash of water.
Just before serving, toast the 0.25 cup chopped toasted pecans in a dry skillet over medium heat for 2-3 minutes until fragrant. Sprinkle them over the top for added crunch and nutty depth. Serve immediately with a side of the pan juices for dipping—this ensures every bite delivers that perfect harmony of herb-roasted turkey and caramelized sweetness.
Pro Tips For Making Turkey Breast And Sweet Potato
- BRINE THE TURKEY 4 HOURS EARLY: I learned this the hard way—dry turkey breast is tough turkey breast. Mix 1 cup kosher salt with 4 cups water, submerge the turkey, and let it soak in the fridge. The salt penetrates deeper than seasoning alone, and the meat stays juicy even when roasted. (Yes, even if you're impatient like me, resist the urge to skip this.)
- TEST SWEET POTATOES WITH A KNIFE: Piercing them once to check doneness is lazy—cut into the thickest part. If the center offers no resistance and the flesh pulls away cleanly from the skin, they're done. Overcooked sweet potatoes turn to mush, and nobody wants that. (Your future self will thank you for not guessing.)
- SEAR THE TURKEY HOT AND FAST: Crank your oven to 425°F (220°C) for the first 15 minutes, then drop to 325°F (165°C). That initial blast builds a crust that locks in flavor, while the lower temp finishes it evenly without drying it out. I used to rush this, and my turkey always came out bland.
- SMASH THE GARLIC: Minced garlic burns. Smash 3-4 cloves with the flat side of your knife, peel, then slice thinly into paper-thin strips. They’ll infuse the dish without turning bitter. (Sounds weird, but it works—trust me.)

Frequently asked questions
Can I use ground turkey instead of turkey breast for this recipe?
Ground turkey would work for a completely different dish—this recipe is designed for roasted turkey breast to achieve that tender, juicy texture. If you're looking for ground turkey, try a stuffing or meatball recipe instead. For this specific dish, boneless turkey breast is ideal because it stays moist and slices beautifully.
How do I adjust the recipe for fewer servings?
For 4 servings, reduce the turkey breast to 1.5 lbs and use 2 medium sweet potatoes. Cut all other ingredients in half, including the herbs, olive oil, and spices. The cooking times will stay similar, but check the turkey's internal temperature at 150°F for 1 hour instead of 160°F.
Why did my turkey breast turn out dry?
Overcooking is the most common cause. Remove the turkey from the oven when it reaches 160°F (it'll rise to 165°F while resting). Another tip: Brining the turkey for 2-4 hours before cooking helps retain moisture. If it's already cooked, try slicing thinly and reheating with a splash of broth in a 325°F oven for 10 minutes.
Can I make this recipe ahead of time?
Cook the turkey and sweet potatoes 1 day ahead. Store the turkey in an airtight container in the fridge, then reheat in a 325°F oven for 20 minutes with a splash of broth. The sweet potatoes reheat well too—just warm in the oven for 15 minutes with a drizzle of water to refresh their glaze.
What's the best way to serve leftovers?
Slice the turkey into sandwiches with crusty bread and a smear of Dijon mustard. The sweet potatoes make a great breakfast hash—crisp them in a pan with eggs and bacon. For a hearty salad, toss turkey slices with mixed greens, avocado, and a honey-mustard dressing. Leftovers keep well for 3-4 days in the fridge.
