This is a homemade take on Dairy Queen’s FlameThrower GrillBurger — a bacon cheeseburger built around layered heat from fresh jalapeños, pepper jack, and a chipotle mayo sauce. The real reason to make it at home is control: you can dial the heat up or down, use better beef, and get a proper sear that a fast-food flat-top rarely delivers.
Why this recipe works
Two things actually move the needle here. First, the chipotle mayo does double duty — it’s the heat source and the moisture layer that keeps the burger from tasting dry, so you’re not adding extra condiments or dirtying extra bowls. Mix it once, use it for everything. Second, toasting the bun cut-side down in the same pan you cooked the bacon in adds flavor from the leftover fat and creates a lightly crisped surface that holds up against the sauce without going soggy. That one pan handles bacon, bun toasting, and if you’re working indoors, the patty too.
Smart swaps
- Pepper jack cheese: If you can’t find it, slice a piece of Monterey Jack and lay a few pickled jalapeño rings directly on top before it melts — same effect, more control over heat level.
- Chipotle peppers in adobo: These come in a can and most stores carry them near the Mexican ingredients. If you’re stuck, a teaspoon of smoked paprika plus a few dashes of hot sauce gets you in the right direction, though the smokiness won’t be as deep.
- Fresh jalapeños: Jarred pickled jalapeños work fine and skip the slicing step entirely. They’re milder and tangier, which some people actually prefer.
- 80/20 ground beef: Don’t go leaner. A 90/10 patty on a hot grill will be dry before it hits 160°F internal — the fat is doing real work here.
Troubleshooting
- Sauce tastes flat or one-note: Chipotle peppers vary a lot by brand. Taste the mayo before you spread it — if it needs brightness, a small squeeze of lime juice fixes it fast. Skip the egg in the mix if a recipe variation suggests it; it makes the sauce heavy and dull.
- Jalapeños sliding out with every bite: Press them lightly into the cheese while it’s still melted and tacky. They’ll bond as it sets and stay put.
- Patty puffing up in the middle: Press a shallow thumbprint into the center of each patty before it hits the heat. The center cooks at the same rate as the edges and the patty stays flat.
- Bun getting soggy fast: Spread the chipotle mayo on both halves right before assembly, not in advance. Sitting time is the enemy — the sauce migrates into the bread quickly.
- Not hitting 160°F without burning the outside: If the crust is darkening before the center is done, drop the heat to medium and tent the patty loosely with a small piece of foil for the last minute or two. It traps enough heat to finish the center without charring.

Instructions
- Make the FlameThrower Sauce (10 minutes active + 15 minutes rest): In a small bowl, whisk together mayonnaise, adobo sauce, minced chipotle (if using), hot sauce, lime juice, smoked paprika, cayenne, and a pinch of kosher salt. Taste and adjust heat and salt. Cover and let the sauce rest 15 minutes in the fridge so the flavors marry.1/2 cup mayonnaise, 1 tbsp adobo sauce from canned chipotle peppers, 1 tsp chipotle pepper, 1 tsp hot sauce, 1 tsp fresh lime juice, 1/2 tsp smoked paprika, 1/4 tsp cayenne pepper, 1 clove garlic, 1 pinch kosher salt
- Cook the Bacon (about 8 minutes): Start bacon in a cold skillet, then set heat to medium. Cook, flipping as needed, until the fat renders and the bacon is deep mahogany and crisp, 7–9 minutes. Transfer to a paper towel–lined plate. Reserve 1 teaspoon bacon fat in the skillet for toasting buns later.4 slices thick-cut bacon
- Preheat Your Cooking Surface: Heat a grill or cast-iron skillet to medium-high — about 450°F (232°C). Lightly oil the grates/pan with neutral oil. If grilling, close the lid to stabilize the temperature.1 tbsp neutral oil
- Prep the Fresh Toppings (5 minutes): Slice jalapeño into rings, slice tomato, and shred the iceberg. Keep lettuce chilled so it stays extra crisp.8-10 pieces fresh jalapeño rings, 4 slices ripe tomato, 1 cup shredded iceberg lettuce
- Form and Season the Patties (2–3 minutes): Divide beef into two 8 oz portions. Shape gently into 4½–5 inch (11–13cm) rounds with a slight centre dimple (prevents doming). Season the first side with kosher salt and pepper right before cooking.1 lb 80/20 ground beef, 1 tsp kosher salt, 1/2 tsp black pepper
- Sear the Burgers (6–7 minutes total): Place patties seasoned-side down onto the hot grill/pan; season the top side. Cook 3–4 minutes until the edges darken and you see fat bead up. Flip; if using Worcestershire, brush lightly now. Top each patty with 2 slices pepper jack during the last 60–90 seconds to melt. For food safety, cook ground beef to an internal temperature of 160°F (71°C) measured at the center with an instant-read thermometer.1 lb 80/20 ground beef, 1 tsp kosher salt, 1/2 tsp black pepper, 1/2 tsp Worcestershire sauce, 4 slices pepper jack cheese
- Blister the Jalapeños (30–60 seconds): While the burgers finish or immediately after, toss jalapeño rings onto the hot pan or grill. Cook just until lightly charred and fragrant, 30–60 seconds, flipping once.8-10 pieces fresh jalapeño rings
- Toast the Buns (30–60 seconds): Spread cut sides of brioche with softened butter and toast cut-side down in the reserved bacon fat or on the grill until golden and crisp at the edges.2 whole brioche burger buns, 1 tbsp unsalted butter
- Assemble and Serve (2 minutes): Spread 1 to 1½ tablespoons FlameThrower sauce on each bottom bun. Add a nest of shredded iceberg and 2 tomato slices. Set the cheesy patty on top, crown with 2 slices bacon and the blistered jalapeños. Swipe 1 tablespoon sauce on the top bun and close. Rest 1 minute for juices to settle, then serve immediately — the burger should look glossy with melted cheese, vibrant green jalapeños, and a golden toasted bun.1/2 cup mayonnaise, 4 slices thick-cut bacon, 4 slices pepper jack cheese, 8-10 pieces fresh jalapeño rings, 4 slices ripe tomato, 1 cup shredded iceberg lettuce, 2 whole brioche burger buns
Notes
Storage: Cooked patties keep refrigerated in an airtight container for up to 3 days. Reheat in a skillet over medium heat — avoid the microwave or the crust goes soft. Leftover FlameThrower sauce keeps refrigerated for up to 5 days. Make-Ahead: Mix the FlameThrower sauce up to 2 days ahead — the chipotle flavour deepens overnight. Cook the bacon up to 1 day ahead and re-crisp in the skillet for 30 seconds per side before assembling. Substitutions: Swap ground beef for ground turkey (cook to 165°F / 74°C), a plant-based patty, or thick portobello caps. Use vegan mayo and plant-based pepper jack to make it dairy-free. Brioche can be replaced with potato buns or pretzel buns. Pro Tips: Pat the formed patties completely dry with paper towels before seasoning — surface moisture is the enemy of a deep, caramelised crust. Season only moments before the patty hits the hot surface so the salt doesn’t draw out more moisture. Heat Adjustment: For a gentler burn, omit the minced chipotle and reduce cayenne to a pinch. For maximum fire, add extra adobo, keep jalapeño seeds, and try ghost pepper jack or habanero cheddar. Alternative Methods: If you don’t have a grill or cast-iron, use a heavy stainless skillet preheated thoroughly. For the sauce, a mortar and pestle will produce an even finer garlic-chile paste; a food processor works too, though it aerates the mayo slightly.

Common questions
How spicy is this burger, really?
It’s a medium heat — noticeable but not punishing for most people. If you want less fire, seed the jalapeños and use half the chipotle in the mayo; if you want more, leave the seeds in and add an extra chipotle pepper to the sauce.
Can I make the chipotle mayo ahead of time?
Yes — it keeps in the fridge for up to five days in a sealed container. The flavor actually improves after a few hours as the chipotle infuses into the mayo.
What internal temperature should the beef patty reach?
Ground beef needs to hit 160°F (71°C) internal — use an instant-read thermometer to be sure. Unlike a whole-muscle steak, ground beef can carry bacteria throughout the patty, so don’t rely on color alone.
Can I cook this on a stovetop instead of a grill?
Absolutely — a cast iron skillet over medium-high heat works well and gives you a solid crust. You can cook the bacon, toast the bun, and sear the patty all in the same pan, which keeps cleanup minimal.
