Ingredients for turkey breast and sweet potato
Pantry staples meet holiday flavors in this one-pan turkey and sweet potato masterpiece.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless Turkey Breast 🦃 | 1 ½ lb | Skin-on preferred for crispiness |
| Sweet Potatoes 🍠 | 2 medium | Peeled, cut into 1-inch cubes |
| Fresh Rosemary 🌿 | ½ oz | Chopped, stems removed |
| Fresh Thyme 🌿 | ¼ oz | Leaves only, stems discarded |
| Garlic Cloves 🧄 | 4 cloves | Minced for even distribution |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | High-quality, fruity variety |
| Honey 🍯 | 1 tbsp | For sweet potato glaze |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly ground for best flavor |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for garnish |
The turkey breast is the star here—bone-in, skin-on if you can find it, but boneless works too. Costco or local butchers often carry pre-trimmings for easier prep. Sweet potatoes should be firm with no soft spots; orange-fleshed varieties like Beauregard roast most evenly. Fresh herbs make all the difference: Trader Joe's sells pre-chopped rosemary and thyme that saves time, but whole sprigs work better for infusing flavor. The honey should be raw or wildflower for deeper flavor—local markets often carry these varieties.
No fresh rosemary? Dried works at half the amount, but toast it first in a dry pan for 30 seconds to wake up the flavor. Substituting sweet potatoes? Yams or regular potatoes both work, but adjust cooking time—they stay denser. Running low on honey? Maple syrup or agave work in a pinch, though honey’s floral notes are ideal. The olive oil is non-negotiable for crispiness; avoid vegetable oil—it won’t caramelize like extra-virgin. For extra richness, brush the turkey with melted butter before roasting (just don’t tell anyone it’s not all olive oil).
Turkey and sweet potatoes keep best in the fridge for 3-4 days when stored separately—turkey in an airtight container, sweet potatoes in a sealed bag. Reheat gently in the oven at 325°F until warmed through. For meal prep, portion into containers with a drizzle of honey and parsley; freezes beautifully for 3 months. The herbs lose potency after 3 days, so add fresh parsley when reheating. This dish reheats even better than it tastes fresh—perfect for leftovers.

Step-by-step instructions for one-pan herb-roasted turkey and sweet potatoes
This method delivers perfectly balanced flavors and textures with minimal cleanup.
Prep the Turkey and Sweet Potatoes
Start by patting the 1.5 lb boneless turkey breast dry with paper towels—this ensures maximum crispiness. Season both sides generously with 1.5 teaspoons salt and 0.5 teaspoon black pepper, pressing firmly so the seasoning adheres. For extra flavor, I like to add a light coating of 2 tablespoons extra-virgin olive oil to the turkey, rubbing it evenly over the surface.
While the turkey seasons, peel and cut the 2 medium sweet potatoes into 1-inch cubes. Toss them in a large bowl with 1 tablespoon honey and 1 teaspoon salt, coating each piece evenly. This pre-seasoning ensures the sweet potatoes develop a caramelized crust while staying tender inside. Keep the turkey and sweet potatoes separate until ready to roast.
Create the Herb Glaze and Layer the Pan
In a small bowl, finely chop the 0.5 ounces fresh rosemary and 0.25 ounces fresh thyme, removing any woody stems. Mince the 4 cloves garlic and combine all three with 1 tablespoon extra-virgin olive oil to create a fragrant herb glaze. Spread this mixture evenly over the turkey breast, pressing gently so it sticks.
Arrange the seasoned turkey breast in a single layer on a rimmed baking sheet, skin-side up if possible. Surround it with the honey-sweetened sweet potato cubes, leaving about 1 inch of space between pieces for even browning. This arrangement ensures the turkey roasts evenly while the sweet potatoes caramelize without steaming.
Roast Until Golden and Tender
Preheat your oven to 400°F for optimal browning. Place the baking sheet on the middle rack and roast for 30 minutes, then reduce the heat to 375°F. This initial high heat jumpstarts the browning process, while the lower temperature ensures even cooking without drying out the turkey.
After 30 minutes, check the turkey's internal temperature with a meat thermometer—it should read 155°F in the thickest part. If the sweet potatoes aren't tender yet (they should pierce easily with a fork), continue roasting for another 15-20 minutes, basting occasionally with the pan juices. The sweet potatoes should be caramelized with crisp edges, while the turkey should be golden and juicy.
Rest and Garnish for Serving
Transfer the turkey to a cutting board and tent loosely with foil. Let it rest for 10 minutes—this crucial step allows the juices to redistribute, preventing dryness. While it rests, return the sweet potatoes to the oven for 5 minutes at 375°F to crisp any remaining soft spots.
Before serving, garnish everything with the 0.25 cup chopped fresh parsley for a pop of color and freshness. Slice the turkey against the grain for tender bites, and serve the sweet potatoes directly from the pan for easy cleanup. The result is a perfectly balanced meal with crispy, caramelized edges and juicy, herb-infused centers.
Pro Tips For Making Turkey Breast And Sweet Potato
- BRINE THE TURKEY: I learned this the hard way—skipping the brine makes turkey breast dry as cardboard. Soak it in ice water with 1 tablespoon salt per cup for 30 minutes minimum. Even if you're short on time, 15 minutes helps, and the texture stays juicy.
- PEEL AND CUBE SWEET POTATOES: Cut them into even 1.5-inch cubes so they cook at the same rate. Uneven pieces mean some burn while others stay raw. A mandoline makes this faster, but a sharp knife works—just don’t rush the cuts.
- SEAR THE TURKEY HOT AND FAST: Cold turkey sticking to the pan is a nightmare. Pat it bone-dry, then sear over high heat for 3–4 minutes per side until golden. This locks in flavor and prevents steaming, which turns turkey bland.
- REST THE TURKEY UNDER FOIL: After roasting, tent it with foil and let it sit for 10–15 minutes. I know, you want to cut into it now, but slicing too soon means dry, stringy meat. The residual heat keeps it moist while you finish the sweet potatoes.
Regional styles of this turkey breast and sweet potato
Southern Comfort Style
In the South, turkey breast and sweet potatoes take on a richer, slightly sweeter profile. I love adding ½ cup pecan pieces to the sweet potatoes during the last 10 minutes of roasting for crunch and depth.
A splash of ¼ cup apple cider poured over the pan before roasting creates a sticky, caramelized glaze that Southern cooks call "sweet potato candy." For the turkey, swap the rosemary for 1 teaspoon smoked paprika and add ½ teaspoon cayenne—this gives it that classic BBQ joint vibe. 🍠
New England Herb Garden
Up north, fresh herbs take center stage. I recommend doubling the rosemary to 1 ounce and adding ½ teaspoon dried sage to the turkey rub.
The sweet potatoes get a glaze of 1 tablespoon maple syrup instead of honey, and I finish with 2 tablespoons chopped chives for a bright, fresh contrast. This version feels lighter but still hearty—perfect for chilly New England winters.
The key is using local honey if available, as it adds subtle floral notes that complement the herbs beautifully.
Midwest Holiday Classic
The Midwest loves its comfort food, so I boost the sweet potatoes with 2 tablespoons brown sugar and ½ teaspoon cinnamon during roasting. For the turkey, I add 1 teaspoon onion powder and ½ teaspoon dried thyme to the seasoning mix.
A drizzle of 2 tablespoons bourbon (like Maker's Mark) over the sweet potatoes before the final 5 minutes of roasting adds a smoky depth that Midwest families adore. Serve with crusty bread to soak up all the juices—this is pure holiday nostalgia. 🦃
Southwest Spiced Fusion
For a Southwest twist, I swap the honey for 1 tablespoon adobo sauce (from canned chipotles) mixed with 1 teaspoon cumin and ½ teaspoon chili powder in the sweet potato toss. The turkey gets a rub of 1 teaspoon ground coriander and ½ teaspoon oregano instead of rosemary.
After roasting, I finish with 2 tablespoons crumbled cotija cheese and ¼ cup chopped cilantro for a bright, tangy kick. This version feels fresh and vibrant while keeping the dish comforting and satisfying.
Pacific Northwest Freshness
Out West, I focus on bright, fresh flavors. The sweet potatoes get a glaze of 1 tablespoon balsamic vinegar and 1 teaspoon Dijon mustard instead of honey, while the turkey is seasoned with 1 teaspoon lemon zest and ½ teaspoon fennel seeds (toasted lightly in a dry pan first).
Garnish with 2 tablespoons chopped dill and a sprinkle of toasted hazelnuts for crunch. This version feels lighter but still rich, with a tangy-sweet balance that Pacific Northwest palates love.

Frequently asked questions
Can I use bone-in turkey breast instead of boneless?
Yes, but you'll need to adjust the cooking time. Bone-in turkey breast takes about 15-20 minutes longer to reach 165°F internally. Use the same seasoning method, but place it skin-side down on the baking sheet first to render fat, then flip halfway through roasting. The bone adds natural moisture, so you may need to reduce oven temperature to 350°F after the initial 30 minutes to prevent overcooking.
How do I prevent the sweet potatoes from burning while the turkey cooks?
Arrange the sweet potatoes around the turkey in a single layer with 1-inch gaps between pieces. Roast at 400°F30 minutes to jumpstart browning, then reduce to 375°F and cover loosely with foil if they're browning too quickly. Basting occasionally with pan juices helps create a caramelized crust without burning.
What's the best way to reheat leftovers?
Reheat turkey and sweet potatoes separately for best results. Place turkey slices on a baking sheet and warm at 325°F for 10-15 minutes until reaching 165°F. For sweet potatoes, cover with foil and reheat at 350°F for 10 minutes. Add a splash of water to the pan to prevent drying. Fresh parsley and a drizzle of honey restore that restaurant-quality finish!
Can I make this recipe in an air fryer?
Preheat air fryer to 400°F and cook turkey breast for 15 minutes, flipping halfway. Toss sweet potatoes with honey and salt, then air fry in batches for 12-15 minutes at 375°F, shaking the basket every 5 minutes. The air fryer creates crispier edges, but you'll need to monitor closely to prevent overcooking the turkey.
What are good side dishes to serve with this?
This dish pairs beautifully with crisp green salads (like arugula with lemon vinaigrette), roasted Brussels sprouts with bacon, or buttery mashed potatoes. For a complete meal, add steamed green beans with almonds or a simple cornbread. The herby flavors in the turkey and sweet potatoes complement lighter sides perfectly while balancing the richness.
