Copycat Bonsai Burger

Kathie Carr


I love Red Robin Bonsai Burgers. I found this copycat recipe in a book of copycats and I changed the seasonings a little. I think its pretty close to the original.

Both the meat and the pineapple need to be marinated (separately) overnight.

I found it hard to estimate prep time. These are not hard to make but the marinade times make them NOT QUICK.

How to Make Copycat Bonsai Burger


  • 1Combine all marinade ingredients in a small saucepan over medium heat. Bring marinade to a boil and then reduce heat. Simmer for 10 minutes, or until sauce thickens. Cover and refrigerate at least 1 hour.

    Place about 1/3 of teriyaki marinade in a large plastic storage container that has a cover. Add the beef patties in a single layer and cover with more marinade. Reserve some marinade for the pineapple slices. Cover container and refrigerate over night.

    Place pineapple slices in a separate container with the remaining marinade, cover and chill over night.

    Do not marinate the meat and pineapple together. They each need to be in separate containers.
  • 2Grill ground round patties about 5 minutes per side, or to desired doneness. Grind a bit of black pepper on each patty as it cooks. When you turn the burgers, add the pineapple to grill and cook until the grill marks show, turning once.

    About 1 minute before the burgers are done, place 2 slices of cheese on top of each patty to melt.

    Spread mayonnaise on the top and bottom of each bun.
    Place hamburger patty on bottom bun and top with 2 tomato slices (salt tomato slices a bit) and 2 grilled pineapple slices.

    Cover with shredded lettuce and top of bun.
