These Hawaiian burgers on the stove are packed with sweet pineapple, savory caramelized onions, and juicy patties cooked right on the stove. Served on Hawaiian rolls, they’re one of the best burgers on the stove for an easy summer meal.
Mix ground beef with 4 tablespoons of sweet and sour sauce and one clove of garlic. Shape into patties slightly larger than the buns (because they'll shrink as they cook). Place the burgers on a baking sheet lined with parchment paper, and refrigerate them for an hour while you prepare the rest of the recipe.
In a small bowl, whisk together the mayonnaise, 2 tablespoons of the sweet n sour sauce (that's ⅛ of a cup), and one clove of garlic. Blend well and refrigerate until you need it.
Heat 3 tablespoons of butter in a large skillet over medium-high heat.
Reduce the heat to medium, and add the onions. Stir infrequently, just enough to prevent burning. Cook until the onions are soft and brown.
You could stop at this point, but if you have the time, I recommend that you sprinkle the onions with a teaspoon of brown sugar and a few teaspoons of water and allow them to caramelize. Keep them over medium heat (or medium-low if they are drying out), and stir when they look like they're starting to stick, every few minutes. You may have to add a little extra oil or butter. As the onions start to stick to the pan, they'll turn brown and develop a really sweet, wonderful flavor. Just be careful that they don't burn because there's nothing wonderful about that flavor. This process will take a half hour or so, but it's well worth it.
Heat a grill pan over medium-high heat on the stove. When the pan is hot, cook pineapple until it is hot and has nice grill marks, about 3 minutes. Flip and grill on the other side. Remove from the pan. Do not clean the pan.
Place the burgers in the grill pan. Cook burgers to an internal temperature of 140ºF, about 4 minutes per side. Add a slice of sharp cheddar cheese to each burger and cook it another minute or so, until the cheese is starting to melt.
Heat griddle to 350ºF. Melt the remaining butter in the microwave in a small bowl. Brush melted butter on the cut side of the rolls and place the rolls butter side down on the griddle for 4 minutes or until they are toasted and golden brown. Remove from griddle and allow to cool for a few minutes.
To serve, spread the sweet n sour mayo on the top and bottom of each toasted bun, top with a burger patty, a slice of grilled pineapple, and some of those delicious sweet onions.
