- 2 fresh jalapeños (thinly sliced): Gives the burgers their signature spicy, smoky punch.
- 4 slices cheddar cheese (or pepper jack for extra spice): Melts beautifully and complements the jalapeños perfectly.
- 4 brioche buns (toasted): Soft and buttery to hold all the juicy burger layers together.
- 2 tablespoons butter: Used to cook the onions and jalapeños for richness and caramelization.
- 2 tablespoons mayonnaise: Adds creaminess to the sauce layer on the buns.

How to Make Jalapeño-Onion Smash Burgers Recipe
Step 1: Prepare the Patties
Start by dividing the ground beef into 4 even portions and loosely shape them into balls. Season them generously with salt, black pepper, and garlic powder. This initial seasoning is crucial as it forms the foundation for every bite bursting with flavor.
Step 2: Cook the Jalapeños and Onions
Heat your cast-iron skillet or griddle over medium-high heat and melt the butter in it. Add the thinly sliced onions and jalapeños, then sauté them for 3 to 4 minutes until they soften and get that slight char. These smoky, tender slices add a perfect balance of sweetness and spice you won’t want to skip. Once done, set them aside.
Step 3: Smash the Burger Patties
Now the fun part—place the beef balls into the hot skillet and smash them firmly with a sturdy spatula until they form thin patties. This smashing technique creates crispy edges that deliver a delightful texture contrast. Cook for 2 to 3 minutes without disturbing so that the burgers develop that signature golden crust.
Step 4: Flip and Add Cheese & Veggies
Flip each patty carefully, then immediately top them with cheddar cheese slices and a generous helping of the cooked jalapeño-onion mixture. The cheese will melt over the spicy toppings, melding all flavors during the last 1 to 2 minutes of cooking while the burgers finish through.
Step 5: Toast and Sauce the Buns
While the burgers are cooking, toast your brioche buns to golden perfection. Mix mayonnaise, ketchup, and mustard together, then spread this flavorful sauce on both toasted bun halves to add a creamy, tangy layer that ties everything together.
Step 6: Assemble and Serve
Layer leaf lettuce and pickle slices on the bun bottoms, then place the molten cheese and jalapeño-onion topped smash burgers over them. Cap with the top bun and serve immediately while everything is warm, juicy, and irresistible.
How to Serve Jalapeño-Onion Smash Burgers Recipe
Garnishes
Keep it simple and fresh with crunchy lettuce and crisp pickles that cut through the richness perfectly. For an extra kick, add sliced avocado or a drizzle of spicy aioli to enhance the layers of flavor. A sprinkle of fresh cilantro can also brighten the palate beautifully.
Side Dishes
Pair your Jalapeño-Onion Smash Burgers with crispy fries, seasoned potato wedges, or a refreshing coleslaw. Grilled corn on the cob or a tangy cucumber salad are excellent choices to balance the burger’s boldness.
Creative Ways to Present
For a fun twist, stack two thinner patties with cheese and jalapeño-onion mix to create double-stacked burgers. Alternatively, serve sliders on mini brioche buns for parties or game day. Adding a fried egg on top can turn this spicy smash burger into an indulgent brunch favorite.
Make Ahead and Storage
Storing Leftovers
If you have any leftover Jalapeño-Onion Smash Burgers Recipe patties, store them in an airtight container in the refrigerator for up to 2 days. Keep the buns separate to avoid sogginess when reheating.
Freezing
You can freeze cooked patties wrapped tightly in plastic wrap and stored in a freezer-safe bag for up to 3 months. Thaw overnight in the fridge before reheating to maintain texture and flavor.
Reheating
Reheat patties gently in a skillet over medium-low heat to retain juiciness and melt the cheese again. Toast the buns separately in the oven or toaster for best results before assembling.
FAQs
Can I use a different type of cheese in this recipe?
Absolutely! While cheddar and pepper jack work wonderfully, you can experiment with Monterey Jack, Swiss, or even a smoky smoked gouda for unique flavor variations.
How can I make the burgers less spicy?
Simply reduce the amount of jalapeños or remove the seeds before slicing, as the seeds carry much of the heat. Alternatively, swap jalapeños for milder poblano peppers for a gentler spice level.
Is it necessary to use a cast-iron skillet?
Cast iron is preferred because it retains heat well and helps create those crispy, caramelized edges that define smash burgers. But a heavy-bottomed stainless steel pan or griddle works as a good substitute.
Can I prepare the jalapeño-onion mixture ahead of time?
Yes, you can cook the jalapeño and onion slices a day in advance and store them in the refrigerator. Reheat briefly before adding to the burgers to save time on burger night.
What’s the best way to smash the burgers without making a mess?
Use a sturdy metal spatula and press firmly but controlled on the beef balls immediately after placing them on the hot skillet. Lip the spatula slightly to create more surface area and prevent sticking.

Instructions
