How to Make Smash Burger Tacos

Step 1: Make the Spread

In a bowl, mix together mayo, ketchup, sweet relish, red onion, vinegar, and sugar.

Chill until ready to use.

Step 2: Assemble the Tacos

Press ground beef evenly onto each tortilla.

Spread a thin layer of mustard on the beef side.

Season with salt and pepper.

Step 3: Sear and Smash

Heat a cast-iron skillet over high heat.

Place the taco, beef-side down, onto the hot pan and smash firmly with a spatula.

Cook until the beef is browned and crispy.

Step 4: Flip and Cheese

Flip the taco, warm the tortilla for a few seconds, and transfer to a plate.

Immediately top with a slice of cheese to melt.

Step 5: Sauté the Onions

In the same pan, add the diced onion and cook in the rendered beef fat until soft and caramelized.

Step 6: Top and Serve

Add a spoonful of the spread to each taco.

Top with sautéed onions, sliced pickles, tomato, and shredded lettuce. Serve hot!

Variations & Swaps

Storage & Make-Ahead Tips

Fridge: Store leftover tacos in an airtight container for up to 3 days.

Do not freeze: The tortillas and toppings won’t hold up well.

Make the spread ahead: It can be stored for up to 1 week in the fridge.
