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


  1. Combine 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.
  2. Grill 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.
