This is a bacon burger built around a sweet-heat sauce — mayonnaise, ketchup, sriracha, honey, and apple cider vinegar — layered with caramelized onions, grilled jalapeños, thick-cut bacon, and melted Monterey Jack on a toasted brioche bun. It takes about 45 minutes start to finish and uses ingredients you can find at any grocery store. If you want a burger that actually tastes like something, this one delivers without requiring any special equipment.
About the ingredients
- 80/20 ground beef: The number refers to the lean-to-fat ratio. Don’t go leaner — 90/10 produces a dry, dense patty. 80/20 is the standard for a reason.
- Applewood-smoked bacon: Any thick-cut bacon works. The “applewood” label just signals a slightly sweet smoke. Regular thick-cut from the butcher counter is fine.
- Monterey Jack: Mild and melts cleanly. Pepper Jack is a direct swap if you want more heat from the cheese layer. Avoid pre-shredded — the anti-caking coating slows melting.
- Apple cider vinegar: This is what keeps the sauce from tasting flat. White wine vinegar works in a pinch, but plain white vinegar is too sharp.
- Brioche or potato bun: Either works. Brioche is richer; potato buns are slightly sturdier. Both toast well. A standard supermarket hamburger bun will go soggy fast under this sauce.
Why this recipe works
Two things make this burger succeed. First, caramelizing the onions low and slow — at least 20 minutes over medium-low heat — converts their sharpness into a deep, mellow sweetness that balances the jalapeño heat without competing with the sauce. Rushing this step on high heat just softens them; it doesn’t develop the same flavor. Second, toasting the bun cut-side down in the same pan creates a thin, lightly crisp layer that holds up against the sauce and juices. Skip the toasting and the bun turns to mush before you finish the first half.
Mistakes to avoid
- Pressing down on the patty while it cooks: It squeezes out the fat and juice. Leave it alone once it hits the pan or grill.
- Skipping the thermometer: Ground beef must reach 160°F (71°C) internal temperature. Color alone is not reliable — a patty can look done and still be underdone in the center.
- Adding the cheese too early: Put it on in the last 60–90 seconds of cooking and cover the pan briefly. Any earlier and it overcooks before the beef is done.
- Making the sauce too far ahead without tasting it: The sriracha and honey flavors shift as they sit. Mix it, taste it, then adjust — more honey for sweet, more sriracha for heat — right before you build the burgers.
- Crowding the bacon in the pan: Overlapping slices steam instead of crisp. Cook in batches if needed, and drain on a paper towel so it stays crispy while you finish the patties. Skip the egg in the beef mix — it makes the patty mushy and isn’t needed when you’re using 80/20.
Leftovers and meal prep
Cooked patties keep in an airtight container in the fridge for up to 3 days. Store the sauce, onions, and bacon separately — stacking them on a cold patty overnight makes everything soggy. To reheat, put the patty in a covered skillet over medium-low heat with a splash of water for about 3 minutes; this steams it back to juicy without drying it out. The sauce keeps refrigerated for up to a week. Raw formed patties can be frozen between sheets of parchment for up to 2 months — thaw overnight in the fridge before cooking, not on the counter.

Ingredients
For the Burger Patties and Toppings
- 2 pounds 80/20 ground beef 900g, freshly ground for best flavour
- 2 teaspoons kosher salt 12g, divided between patties
- 1 teaspoon black pepper coarsely ground
- 8 slices thick-cut bacon applewood smoked preferred
- 1 large yellow onion thinly sliced
- 1 tablespoon unsalted butter 14g
- 4 slices Monterey Jack cheese or Pepper Jack for extra kick
- 4 whole brioche burger buns lightly buttered and toasted
- 2-3 pieces fresh jalapeños sliced into rounds, seeds removed for milder heat
For the Sweet & Spicy Sauce
- ½ cup mayonnaise 120g, full fat for creaminess
- 3 tablespoons ketchup 45g
- 1 tablespoon honey 21g
- 2 tablespoons sriracha 30ml, adjust to heat preference
- 1 teaspoon apple cider vinegar 5ml
Instructions
- Prepare the Sauce: In a bowl, whisk together the mayonnaise, ketchup, honey, sriracha, and apple cider vinegar until smooth. Taste and adjust for sweetness or spice. Set aside or refrigerate.1/2 cup mayonnaise, 3 tablespoons ketchup, 1 tablespoon honey, 2 tablespoons sriracha, 1 teaspoon apple cider vinegar
- Cook the Bacon: In a skillet over medium heat, cook the bacon until crispy, about 6–8 minutes. Drain on a wire cooling rack and set aside.8 slices thick-cut bacon
- Caramelize the Onions: In the same pan, add 1 tablespoon unsalted butter and the sliced onions. Cook over medium-low heat, stirring occasionally, until deeply golden brown and sweet, about 20–25 minutes. Do not rush on high heat — the onions should collapse to roughly a quarter of their raw volume. Set aside.1 tablespoon unsalted butter, 1 large yellow onion
- Char the Jalapeños: In a dry skillet or on the grill over medium-high heat, cook the jalapeño slices for 1–2 minutes per side until lightly charred and slightly softened. Set aside.2-3 pieces fresh jalapeños
- Form and Season the Burger Patties: Divide ground beef into 4 equal portions (1/2 pound each). Gently form into patties about 4.5 inches wide. Season both sides generously with kosher salt and black pepper.2 pounds 80/20 ground beef, 2 teaspoons kosher salt, 1 teaspoon black pepper
- Cook the Patties: Heat a cast iron skillet or grill to medium-high heat (about 400°F / 200°C). Sear patties for 3–4 minutes per side. In the final minute of cooking, place cheese over patties and cover to melt.4 slices Monterey Jack cheese
- Toast the Buns: Lightly butter burger buns and toast on a skillet until golden brown. This adds texture and prevents sogginess from the sauce.4 whole brioche burger buns
- Assemble the Burgers: Spread the sweet & spicy sauce on both bun halves. Layer the bottom bun with charred jalapeño slices, cheese-covered patty, 2 slices of bacon, caramelized onions, and top bun. Serve immediately.2-3 pieces fresh jalapeños, 4 slices Monterey Jack cheese, 8 slices thick-cut bacon, 1 large yellow onion

Frequently asked questions
Can I make this on an outdoor grill instead of a stovetop?
Yes — cook the patties over direct medium-high heat and use a meat thermometer to confirm 160°F (71°C) internal temperature before pulling them. Do the bacon and onions in a cast-iron skillet set on the grill grate, since grill grates aren’t practical for either.
How do I know when the onions are actually caramelized and not just cooked?
They’re done when they’ve collapsed to roughly a quarter of their raw volume and turned a deep golden-brown color — not pale yellow, not translucent. This takes a genuine 20–25 minutes on medium-low heat; if yours are done in 10 minutes, the heat is too high.
My sauce came out too runny. What went wrong?
The most common cause is using a thin or low-fat mayonnaise — full-fat mayo gives the sauce its body. Stir everything together and let it sit for 5 minutes; it thickens slightly as the ingredients combine. If it’s still too loose, add another tablespoon of mayo.
