Jalapeño Smash Burgers Recipe
Introduction
Jalapeño Smash Burgers are a flavorful twist on a classic favorite, combining spicy charred jalapeños, melted brie, and crispy golden leeks. This burger offers a perfect balance of heat, creaminess, and crunch, making it an exciting option for your next meal.

Ingredients
- 4 large jalapeños, sliced
- 1 large leek (or 2 medium ones)
- Olive oil for frying
- 4 Omaha Steak Smash Burgers
- Salt and pepper, to taste
- 4 thick slices of brie
- 2 brioche buns
- Honey, to taste
- 2 tbsp mayo
- 1 tbsp Dijon mustard
- 1 tsp honey (for dijonaise)
- Kettle chips, for serving
- Cornichons, for serving
Instructions
- Step 1: Slice the jalapeños into thick rounds. Heat a pan on medium-high for 2 minutes and add a little olive oil. Add the jalapeño slices and cook until they develop a nice char.
- Step 2: Trim the root end and tough dark green tops off the leek. Peel away any loose outer layers. Slice the leek in half lengthwise, lay flat, and cut into thin matchstick pieces. Rinse the sliced leeks in cold water to remove dirt, then drain and dry thoroughly.
- Step 3: Place the leeks in a cold pan with enough olive oil to coat. Turn the heat to high for 1 minute, then reduce to low and cook gently until golden. Remove from pan and set aside.
- Step 4: In a small bowl, combine mayo, Dijon mustard, and 1 tsp honey to create a smooth dijonaise sauce.
- Step 5: Preheat your grill or pan. Season the smash burger patties with salt and pepper. Cook each patty for 2½ minutes per side until caramelized edges form. Top each patty with a thick slice of brie and allow it to melt briefly.
- Step 6: Lightly grill the brioche buns until golden and warm.
- Step 7: Assemble the burgers by spreading dijonaise on the bottom bun. Add one patty, a layer of charred jalapeños, a drizzle of honey, then the second patty, more jalapeños, more honey, and finish with the crispy leeks. Top with the bun and serve immediately with kettle chips and cornichons.
Tips & Variations
- For less heat, remove the seeds and membranes from the jalapeños before charring.
- Substitute brie with a melty cheese like Havarti or Monterey Jack for a different flavor.
- Try adding avocado slices for extra creaminess.
- Use a cast-iron skillet if you don’t have a grill for great caramelization on the patties.
Storage
Store any leftover cooked patties and toppings separately in airtight containers in the refrigerator for up to 2 days. Reheat the patties gently in a pan over medium heat to keep them juicy. Avoid assembling stored burgers until ready to serve to maintain crispness, especially of the leeks and buns.

Serve this delicious recipe with your favorite sides.
FAQs
Can I make these burgers vegetarian?
Yes, you can substitute the beef smash patties with plant-based burger patties or thick grilled portobello mushrooms, adjusting cooking times accordingly.
How do I control the spiciness of the jalapeño?
Removing the seeds and white membranes inside the jalapeños will significantly reduce their heat. Additionally, charred jalapeños develop a smoky flavor that balances heat nicely.

Ingredients

- 1 large leek (or 2 medium ones), cleaned and thinly sliced
Meat and Cheese
- 4 Omaha Steak Smash Burgers
- 4 thick slices of brie cheese
Buns and Condiments
- 2 brioche buns
- 2 tbsp mayonnaise
- 1 tbsp Dijon mustard
- 1 tsp honey (plus extra honey to taste for topping)
Oils and Seasonings
- Olive oil for frying
- Salt and pepper to taste
Sides
- Kettle chips
- Cornichons
Instructions
- Char the Jalapeños: Slice the jalapeños into thick rounds. Preheat a pan on medium-high heat for 2 minutes, add a little olive oil, and then add the jalapeño slices. Cook until they develop a nice char, adding smoky heat to your burgers.
- Prepare the Leeks: Trim the root ends and dark green tops from the leek. Peel off any loose outer layers. Slice the leek lengthwise in half, then lay each half flat on a cutting board and cut into thin matchstick-sized pieces. Rinse the sliced leeks thoroughly in cold water to remove dirt, then drain and dry well.
- Caramelize the Leeks: Add the cleaned leeks to a cold pan with enough olive oil to cover them. Turn heat to high for 1 minute, then lower heat to low and cook gently until the leeks turn golden and caramelized. Remove from heat and set aside.
- Make the Dijonaise: In a small bowl, mix mayonnaise, Dijon mustard, and 1 teaspoon honey to create a sweet and tangy dijonaise sauce.
- Grill the Burgers: Preheat your grill or grill pan. Season the patties with salt and pepper, then cook each side for approximately 2½ minutes until caramelized edges form. During the last moments of cooking, place a slice of brie on each patty to melt slightly.
- Toast the Brioche Buns: Lightly grill the brioche buns until they are golden and warm for added texture and flavor.
- Assemble the Burgers: Spread the dijonaise sauce on the bottom halves of the buns. Layer with one brie-topped patty, then charred jalapeños and a drizzle of honey. Add the second patty, more jalapeños, honey again, and finish with a generous handful of caramelized leeks. Top with the bun halves.
- Serve: Serve the assembled jalapeño smash burgers immediately with kettle chips and cornichons on the side for an extra crunch and tangy bite.
Notes
- You can adjust the amount of honey to balance the spiciness of the jalapeños according to your taste.
- If Omaha Steak Smash Burgers are unavailable, use any high-quality thin smashed beef patties for best results.
- Make sure to thoroughly clean the leeks as they tend to trap dirt between layers.
- Charred jalapeños add a smoky depth; if preferred less spicy, remove the seeds before slicing.
- Toasting brioche buns enhances flavor and prevents sogginess from the sauces.
