- 1 large sweet onion such as Vidalia, Maui, or Walla Walla, very thinly sliced
- 4 small-medium tomatoes
- 1 tablespoon white sugar
- 1 tablespoon brown sugar
- 2 tablespoons fresh lemon juice from about ½ lemon
- 2 tablespoons apple cider vinegar
- 2 teaspoons Kosher salt
- 1 teaspoon dry mustard powder
- 1 pinch red chili flakes optional
For the Burgers
- 8 slices bacon thick-sliced
- 2 lbs ground beef freshly ground chuck or 80/20

Make the Tomato Onion Jam
Heat the olive oil in a medium sauté pan over medium heat. Add the onions and cook slowly until they begin to lightly caramelize, about 15 minutes.
Slice the tomatoes in half, squeeze out the seeds, and roughly chop.
Add the chopped tomatoes to the pan along with the brown sugar, granulated sugar, lemon juice, vinegar, salt, mustard powder, and chili flakes.
Let the mixture simmer and cook down until it thickens, about 15–20 minutes. Stir occasionally to prevent sticking.
Turn off the heat and allow the jam to cool. Transfer to a jar or container.
Make the Burgers
Preheat the oven to 350°F (175°C).
Arrange the bacon on a foil-lined sheet pan and bake until crisp, about 15–20 minutes.
Transfer to paper towels to drain and set aside.
Divide the ground beef into 4 even portions. Gently shape each into a wide patty, making the center slightly thinner than the edges.
Season both sides of the patties generously with salt and pepper.
Preheat a grill or grill pan over high heat. Cook the burgers until nicely charred on one side.
Flip the burgers and top each with a slice of cheese. Close the grill (or cover the pan) to melt the cheese.
Cook to your desired doneness—medium with a pink center is recommended.
Assemble and Serve
Place each patty on a bun. Top with two slices of bacon and a generous smear of tomato onion jam.
Serve immediately and enjoy!
-
Don’t overwork the beef when forming patties—it makes the texture tough.
-
The jam makes about 3 cups and keeps in the fridge for up to 3 weeks—perfect for burgers, grilled cheese, or even breakfast eggs.
-
Always toast the buns for extra texture and flavor.
-
Use a grill press or cover to help the cheese melt evenly.
