How to Make Jalapeño-Onion Smash Burgers
Step 1: Prep the Ingredients
Thinly slice the onions and jalapeños to ensure even cooking and better flavor distribution. Divide the ground beef into four equal portions, but don’t overwork them. The looser the meat, the juicier the patty will be.
Step 2: Cook the Onions & Jalapeños
Heat a cast-iron skillet over medium heat with butter. Toss in the onions and cook them until they turn golden brown and caramelized. Add the jalapeños and cook for another two minutes. Remove them from the pan and set aside.
Step 3: Smash the Burger Patties
Increase the heat to high and drizzle a little vegetable oil onto the skillet. Place a beef ball on the pan, then immediately press it down using a spatula or a burger press. Flatten it as thin as possible to get that crispy edge. Sprinkle with salt, pepper, and garlic powder. Cook for about two minutes, then flip, add cheese, and let it melt over the patty.
Step 4: Assemble the Burger
Toast the burger buns with butter for extra flavor. Place the cheesy patty on the bottom bun, then top it with the caramelized onions and jalapeños. Add your favorite sauce, cover with the top bun, and enjoy!
Tips for the Best Jalapeño-Onion Smash Burgers
Choosing the Right Beef

Perfecting the Smash Technique
- Smash within 30 seconds of placing the meat on the pan to lock in juices.
- Use high heat to create that signature crispy crust.
Adjusting the Spice Level
- Want it spicier? Add pickled jalapeños or a few dashes of hot sauce.

FAQ – Jalapeño-Onion Smash Burgers
1. What makes a smash burger different from a regular burger?
Smash burgers are pressed thin on a hot griddle, creating crispy edges and a juicier center. The technique enhances the flavor by allowing maximum contact with the pan.
2. Can I make this burger without a cast-iron skillet?
Yes! A stainless steel pan or flat-top grill will work just as well. Just make sure the surface is extremely hot before adding the beef.
3. How do I make a smash burger extra crispy?
The key to crispiness is high heat and not moving the patty after smashing it. Let it cook undisturbed for the best crust.
4. Can I use turkey instead of beef?
Yes, but turkey has less fat, which means it can dry out quickly. Add a small amount of butter or oil to keep it juicy.
5. What sauces pair best with this burger?
Try chipotle mayo, garlic aioli, or classic burger sauce to enhance the flavors and complement the spice.
