Instructions

  1. 1

    Slice the white onion into thick rounds, about 1/4 to 3/8 inch thick. Keep the rings intact — they will sit on top of the patties.

  2. 2

    In a large bowl, combine the ground beef, ground flaxseed, and eggs. Season generously with salt and pepper.

  3. 3

    Mix by hand just until evenly combined — don't overwork or the burgers will be tough.

  4. 4

    Let the mixture rest 5 minutes so the flaxseed absorbs moisture and helps bind.

  5. 5

    Form into 6 equal patties, about 3/4 inch thick. Make a small depression in the center of each with your thumb (helps them cook flat instead of doming).

  6. 6

    Lay one or two onion rounds on top of each patty, covering as much surface as possible so the onion juices drip down into the beef as it cooks.

  7. 7

    Smoker method (preferred): Set up your smoker with your wood of choice — hickory, mesquite, or apple work well. Bring the smoker to 225°F. Smoke the patties (with onion on top) for 45-60 minutes until the internal temperature reaches 160°F.

  8. 8

    Grill alternative: Preheat grill to medium-high. Grill the patties (onion on top) for 4-5 minutes per side — when flipping, keep the onion rings layered on top of the cooked side so the juices continue to drip into the meat. Cook until internal temp reaches 160°F.

  9. 9

    Let the burgers rest 3-5 minutes before serving, with the smoked/grilled onion still on top.
