Slow-cooked onions add moisture and flavor to these lean beef burgers. A quick blend of mayonnaise, ketchup, relish and vinegar makes a perfect tangy, sweet and creamy “special sauce” for this burger. We love the dill relish here, but use sweet relish if you prefer it. Serve with sweet potato fries. Source: EatingWell Magazine, May/June 2011

Ingredient Checklist


Instructions Checklist
  • Preheat grill to medium-high (or see Stovetop Variation).

  • Combine onion, oil and 1 tablespoon ketchup in a medium saucepan. Cover and cook over medium-high heat, stirring often, until the onion is softened, 5 to 7 minutes. Reduce heat to medium-low, uncover and cook, stirring occasionally, until very soft, 5 to 8 minutes more. Transfer to a medium bowl and let cool for a few minutes.

  • Meanwhile, combine the remaining 1 tablespoon ketchup, mayonnaise, relish and vinegar in a small bowl. Set aside.

  • Add beef, Worcestershire (or steak sauce) and pepper to the onion and gently combine without overmixing. Form into 4 patties, about 3/4 inch thick.

  • Oil the grill rack (see Tip). Grill the burgers, turning once, until an instant-read thermometer inserted in the center registers 165 degrees F, 4 to 5 minutes per side.

  • Assemble the burgers on toasted buns with the ketchup-mayonnaise sauce, tomato slices and lettuce.


Make Ahead Tip: Prepare ketchup-mayonnaise sauce (Step 3) and refrigerate for up to 1 day.

Stovetop Variation: Coat a nonstick pan, preferably cast-iron (or a grill pan), with cooking spray and heat over medium-high heat for 1 to 2 minutes. Add burgers, reduce heat to medium and cook, turning once, until an instant-read thermometer registers 155°F (for pork and bison) or 165° (for beef or chicken), 4 to 5 minutes per side.

Tip: To oil a grill rack, oil a folded paper towel, hold it with tongs and rub it over the rack. (Do not use cooking spray on a hot grill.)

Best Healthy Beef Burger Recipe EVER This is my go-to burger recipe now. I use 93% - 96% lean ground beef but the burgers are very moist and flavorful due to the sauteed onion/ketchup mixture and small amount of oil for the saute (I use olive oil for a healthier choice.) I don't make the extra sauce but these burgers are a giant hit with everyone EVERY TIME. My 10-year-old niece and nephew BEG me to make these any time we visit! I hope your family will enjoy this recipe as much as mine does. Pros: Easy common ingredients Cons: None Read More
