These Diablo Turkey Burgers pack serious heat from crushed red pepper flakes and get a smoky, slightly sweet finish from homemade roasted red peppers. The whole recipe — peppers included — comes together in 40 minutes, and the roasted peppers keep in the fridge for up to three weeks, so making a big batch now pays off all week long. At 203 calories and 41 grams of protein per patty, they pull real weight without a lot of effort.
Before you start
Two things actually matter here. First, the thumb indentation in the center of each raw patty is not optional — ground turkey has less fat than beef, which means it tightens and domes aggressively over heat, and a shallow dimple keeps the patty flat enough to cook evenly all the way through to the required 165°F (74°C) internal temperature. Use an instant-read thermometer; color alone is not a reliable guide with turkey. Second, do the roasted peppers first. The sweating step — sealing the hot charred peppers in a bag or covered bowl for 10 minutes — is what loosens the skin so it scrapes off cleanly. Rush it and you’ll spend twice as long picking off stubborn bits. If you’re making a double batch of peppers to use through the week, they store covered in the fridge for up to three weeks, so the extra broiler time is worth it.
About the ingredients
- Ground turkey (93/7): Use 93/7 lean-to-fat ground turkey. Anything leaner — 99/1 — produces a dry, crumbly patty that’s hard to hold together without binders. Stick with 93/7.
- Crushed red pepper flakes: Two teaspoons is genuinely spicy. If you’re cooking for mixed heat tolerances, start with one teaspoon and taste the raw mix before forming patties.
- Fresh basil vs. dried: Dried basil works fine here — use 1 teaspoon in place of the ¼ cup fresh. The flavor is less bright but still comes through once the garlic and pepper flakes are in the mix.
- Red bell peppers: Any color bell pepper roasts well, but red ones are sweeter and balance the chili heat better than green. They’re also typically cheaper in bulk, which matters if you’re roasting a larger batch to use across multiple meals.
Mistakes to avoid
- Mixing the meat too long: Once the ingredients look evenly distributed, stop. Overworking ground turkey develops the proteins and makes the finished patty dense and rubbery. A brief fold-and-press is all it needs.
- Skipping the salt until after cooking: The recipe calls for salting right before the grill, which is correct — salting too early draws moisture out of the patty and can make it fall apart on the grate. Don’t season the mix in the bowl.
- Pulling the patties too soon: Skip the egg in the mix — it makes the patty mushy — but do let each patty develop a full sear before flipping. Turkey sticks badly to a grill or pan when it’s undercooked; it releases naturally once a proper crust forms, usually around the 5-minute mark per side.
- Storing assembled burgers: If you’re prepping these ahead, store patties and roasted peppers separately in the fridge (patties up to 2 days raw, or freeze them flat for up to 3 months). Assembling in advance makes the bun soggy and the pepper strips lose their texture.
- Using a cold pan: Whether you’re on a grill or a cast iron skillet, make sure it’s fully preheated to medium-high before the patties go on. A lukewarm surface steams the meat instead of searing it, and you lose the crust that holds everything together.
Spicy Diablo Turkey Burgers With Roasted Peppers
Equipment
- Rimmed baking sheet
- Large mixing bowl
- Grill or cast iron skillet (12-inch)
- Instant-read thermometer
- Tongs
- Heavy-duty zip-top bags or heatproof bowl with plastic wrap
Ingredients
For the Roasted Peppers
- 3 medium red bell peppers
For the Burgers
- 1 ½ pounds ground turkey 680g
- ¼ cup fresh basil leaves chopped, or 1 teaspoon dried basil
- 3 cloves garlic minced
- 2 teaspoons crushed red pepper flakes
- 1 teaspoon dried oregano
- ½ teaspoon kosher salt or to taste
- ¼ teaspoon ground black pepper or to taste
For Serving
- 4 whole burger buns brioche or standard
Instructions
Roast the Peppers
- Preheat the broiler to high (500°F / 260°C if your oven has an adjustable broiler setting). Cut off the top and the bottom of each pepper, so they look like short columns. Then slit the pepper open and discard the membranes and seeds. Lay them out flat on a rimmed baking sheet, shiny side up.3 medium red bell peppers
- Place directly under the broiler, about 4 inches from the heat source, and cook until the skin is fully charred and blistered, about 5–8 minutes. Watch closely — broilers vary significantly.3 medium red bell peppers
- While still hot, remove the peppers and place them in a heavy-duty zip-top bag or heatproof bowl covered with plastic wrap; let sweat for about 10 minutes. Scrape off and discard the burned skin. Set peppers aside to cool. Cut into strips, cover and refrigerate for up to 3 weeks.3 medium red bell peppers
Make the Burgers
- Place the ground turkey, basil, garlic, red pepper flakes and oregano in a large mixing bowl. Mix the ingredients until all are well incorporated. Divide the meat mixture into 4 balls of equal size. Form each into a patty. Using your thumb, make a 1/2-inch indentation in the center of the burger to ensure more even cooking. Handle the patties as little as possible.1 1/2 pounds ground turkey, 1/4 cup fresh basil leaves, 3 cloves garlic, 2 teaspoons crushed red pepper flakes, 1 teaspoon dried oregano
- Preheat a grill or grill pan/cast iron skillet to medium-high.
- Sprinkle both sides of the burgers with salt and pepper.1/2 teaspoon kosher salt, 1/4 teaspoon ground black pepper
- Grill the patties until well seared on both sides and an instant-read thermometer inserted into the thickest part reads 165°F / 74°C, about 5–6 minutes per side. Do not serve turkey burgers below this temperature.1 1/2 pounds ground turkey
- Once cooked, transfer the patties to buns or a serving platter and serve immediately topped with the roasted peppers and with extra whole basil leaves, if desired.3 medium red bell peppers, 4 whole burger buns, 1/4 cup fresh basil leaves
- Alternatively, place a grill pan/cast iron skillet over medium-high heat. Once hot, add the burgers to the dry pan and cook until well seared on both sides and an instant-read thermometer reads 165°F / 74°C, about 5–6 minutes per side (10–12 minutes total).1 1/2 pounds ground turkey

Frequently asked questions
Can I freeze these turkey burger patties before cooking?
Yes — freeze raw patties flat on a parchment-lined sheet until solid, then transfer to a zip bag for up to 3 months. Thaw overnight in the fridge before cooking; don’t cook from frozen or the outside will overcook before the center hits the safe 165°F (74°C) internal temperature.
How do I know when the turkey burgers are done without cutting them open?
Use an instant-read thermometer inserted sideways into the thickest part of the patty — you’re looking for 165°F (74°C). Unlike beef, turkey shows no reliable visual cues like juice color, so a thermometer is the only accurate method.
Can I make the roasted peppers on the stovetop instead of under the broiler?
Yes — hold each pepper directly over a gas burner on high heat, turning with tongs, until the skin is fully charred on all sides, then sweat and peel as the recipe describes. It takes about 8–10 minutes per pepper and works just as well as the broiler method.
What bun works best with these, and does it need anything on it?
A sturdy brioche or potato roll holds up to the juicy pepper strips without going soggy. A thin spread of garlic aioli or even plain mayo on both cut sides adds enough fat to complement the lean turkey patty without competing with the chili heat.
