These are lean turkey burgers seasoned with grated onion, Dijon mustard, and garlic, cooked in a skillet and served alongside oven-roasted sweet potato wedges. The honest reason to make them: the whole meal is on the table in about 40 minutes, uses one pan and one sheet tray, and the cleanup is minimal. Turkey burgers get a bad reputation for being dry — this recipe has a few small tricks that fix that.
Before you start
Two things actually matter here. First, do not skip the grated onion — it adds moisture directly into the mix, which is the main reason lean turkey stays juicy instead of turning chalky. Grate it on the fine side of a box grater and squeeze out just a little of the liquid before adding it; too much water and the patties won’t sear properly. Second, get the sweet potato wedges into the oven before you touch the turkey. They need 25–30 minutes at high heat and they can hold warm easily, so starting them first means everything finishes together without you having to rush the burgers. Skip the egg in the mix — it makes the patty mushy and the grated onion already does the binding work you need.
Keeping and reheating
Cooked turkey patties keep in the fridge for up to 4 days in an airtight container. Reheat them in a covered skillet over medium-low heat with a splash of water — about 3 minutes per side — and they come back close to fresh without drying out. The microwave works in a pinch but tends to toughen the edges. Roasted sweet potato wedges keep for 3 days refrigerated; reheat them on a bare sheet tray at 400°F for 8–10 minutes to get some crispness back. For freezing, wrap raw patties individually in plastic wrap, then bag them — they’ll keep for up to 3 months. Thaw overnight in the fridge before cooking; do not cook from frozen or the outside will scorch before the center reaches the required 165°F internal temperature for ground poultry.
Mistakes to avoid
- Packing the patties too tight. Overworking the turkey mix compresses the proteins and produces a dense, rubbery patty. Mix just until the ingredients are combined — stop as soon as you don’t see dry pockets.
- Crowding the skillet. If the patties are touching, they steam instead of sear and you lose the browned crust. Use a 12-inch skillet or cook in two batches.
- Pulling the patties too early. Ground turkey must hit 165°F internal — use an instant-read thermometer. Cutting into them to check lets the juices run out and you end up with a dry burger regardless of how well you seasoned it.
- Cutting the sweet potato wedges unevenly. Thick wedges on the same tray as thin ones means some burn before others are cooked through. Aim for uniform 3/4-inch thickness so they roast at the same rate.
- Not drying the sweet potato wedges before seasoning. Surface moisture turns into steam in the oven and prevents browning. Pat them dry with a paper towel after cutting, then toss with oil and spices.
Turkey Burger with Roasted Sweet Potato Wedges
Ingredients
For the Roasted Sweet Potato Wedges:
- 2 medium sweet potatoes peeled and cut into thick wedges
- 2 tablespoons olive oil extra virgin
- 1 teaspoon smoked paprika
- ½ teaspoon garlic powder
- ½ teaspoon sea salt or to taste
For the Turkey Burgers:
- 1 pound ground turkey 93% lean for optimal juiciness
- ¼ cup finely grated onion with juices
- 2 cloves garlic minced
- 1 teaspoon Dijon mustard
- ½ teaspoon kosher salt
- ¼ teaspoon black pepper freshly ground
- 1 tablespoon olive oil for sautéing
To Serve:
- 4 pieces whole-grain burger buns lightly toasted
- 1 cup lettuce leaves washed and dried
- 1 medium tomato sliced into rounds
- 4 slices red onion optional, raw or grilled
Instructions
- Preheat the oven to 425°F (220°C). Line a baking sheet with parchment paper.
- Prepare the Sweet Potato Wedges: In a large bowl, toss sweet potato wedges with olive oil, smoked paprika, garlic powder, and sea salt. Spread them out in a single layer on the prepared baking sheet. Roast for 25–30 minutes, flipping once halfway through, until they're golden and crisp on the edges.
- While the Potatoes Roast, Prepare the Turkey Burger Mix: In a mixing bowl, combine the ground turkey, grated onion (with its juices), minced garlic, Dijon mustard, kosher salt, and black pepper. Mix gently with clean hands or a spatula—do not overwork, or the burgers will be tough.
- Form into Patties: Divide the turkey mixture into 4 equal parts and shape into burger patties about 1/2-inch thick. Press a small indentation into the center of each to help retain shape while cooking.
- Cook the Burgers: In a skillet over medium heat, add 1 tablespoon olive oil. When hot, add the patties and cook for 5–6 minutes per side or until the internal temperature reaches 165°F (74°C). Let rest for 3 minutes after cooking.
- Assemble the Burgers: Place each patty on a toasted bun and top with lettuce, tomato slices, and onion. Serve with roasted sweet potato wedges on the side.
Notes
Chef’s Tips:
- For a juicy burger, don’t skip the grated onion—it adds both moisture and flavor.
- For a spicy kick, add a pinch of chili flakes to the turkey mixture.
- You can also swap sweet potato wedges for baked zucchini fries in the warmer months.
- If time permits, refrigerate patties for 15 minutes before cooking—they’ll hold their shape better during searing.

FAQ
Can I use 99% fat-free ground turkey instead of 93% lean?
You can, but the patties will be noticeably drier and more prone to falling apart. The small amount of fat in 93% lean turkey is what carries flavor and holds moisture — if 99% is all you have, add an extra tablespoon of olive oil directly into the mix.
How do I know when the turkey burgers are done without a thermometer?
You really need a thermometer — ground poultry must reach 165°F (74°C) and there is no reliable visual shortcut. A $10 instant-read thermometer is the only way to be sure without cutting the patty open and losing the juices.
Can I make the patties ahead of time?
Yes — form them up to 24 hours in advance, cover tightly, and refrigerate. Keep them cold right up until they go in the pan; letting raw turkey patties sit at room temperature before cooking increases the risk of uneven cooking and food safety issues.
My sweet potato wedges always come out soft instead of crispy — what am I doing wrong?
The two most common causes are wet wedges and an overcrowded pan. Pat the cut wedges dry before oiling them, and make sure they are in a single layer with space between each piece — if they touch, they steam and go soft.
Can I grill these turkey burgers instead of using a skillet?
Yes, but chill the patties for at least 30 minutes before grilling so they hold together on the grates. Lean turkey patties are more fragile than beef — a well-oiled grill and cold, firm patties are what keep them from sticking and breaking.
What whole-grain buns work best and do I have to toast them?
Any whole-grain sandwich bun works — look for ones that aren’t too thick or they’ll overpower the patty. Toasting is worth the 60 seconds: it creates a slight barrier so the bun doesn’t go soggy from the burger’s juices while you’re plating.
