Holly’s Recipe Highlights

  • Flavor: These burgers have a delicious smoky flavor, complemented by sweet grilled peppers, fresh cilantro, and a tangy sauce for the perfect burger-meets-fajita flavor mashup.
  • Budget: This easy recipe is perfect for weeknights, but using ground turkey and peppers makes this colorful burger affordable for a crowd.
  • Recommended Tools: All you need is a grill, mixing bowls, a cutting board, sharp knife, and a spatula. Use an instant-read thermometer for safely cooked and juicy burgers.
  • Serving Suggestions: I love serving these tender turkey burgers in lettuce wraps or burger bowls for an easy backyard dinner. Add avocado or sliced tomato for even more flavor.

Ingredients

  • Turkey: Using lean ground turkey keeps the burgers light tasting. Avoid extra lean ground turkey because the burger can dry out faster.
  • Veggies: Use half of the bell peppers and onion in the patties for added moisture and flavor, while the rest are grilled for topping. A mix of colors looks best and adds natural sweetness. Red onion is a bit sweeter than white or yellow varieties.
  • Sauce: This bright and tangy southwest sauce brings all the flavors together. Try a DIY fajita, Southwest, or taco seasoning recipe. Swap in sour cream in place of the yogurt and mayo, if desired.
  • Variations: For a milder, smoky flavor, use poblano instead of jalapeno, or skip the pepper entirely for a family friendly version. Add pepper jack cheese in the last minute for a cheesier Southwest burger.

How These Burgers Come Together

  1. Mix the sauce ingredients.
  2. Prepare veggies (full recipe below).
  3. Combine turkey with diced veggies and seasoning.
  4. Divide into patties and grill along with reserved veggies.
  5. Top each patty with grilled veggies and southwest sauce.

Holly’s Best Burger Tips

  • Gently mix ground turkey so the patties stay tender.
  • Dice the veggies added to the ground turkey small so the patties hold together well. Chill the formed patties for 15 to 20 minutes.
  • To prevent the burgers from sticking to the grill, oil or spray the outside of the patties, not the grill grates.
  • Cook only to a safe 165˚F, do not overcook. Let the burgers rest a few minutes before serving for juicy burgers.
  • Make extra sauce and use as a veggie dip or to drizzle over leftover veggies.

Save It For Later

  • Refrigerate leftover cooked burgers, grilled vegetables, and sauce separately. Cooked burgers and sauce will keep in airtight containers for up to 4 days.
  • Store frozen or uncooked patties in layers with parchment for up to 3 months.
  • Thaw frozen, cooked patties in the refrigerator overnight, then reheat in a skillet, in the microwave, or in the oven, covered.
