Smashburger quesadillas are the genius mashup you didn’t know you needed. Think crispy, lacy-edged smash patties loaded with gooey melted cheese, all wrapped up in a golden buttery tortilla.
If you love smashburgers and you love quesadillas, this is about to become your new obsession.
Trust me, once you try this combo, there’s no going back.

Why This Recipe Works
The magic here is all about the contrast. You get that irresistible crispy-edged smashed beef on the inside, paired with melty American cheese that practically fuses everything together.
Then you wrap it all in a buttered flour tortilla and griddle it until it’s golden and crunchy on the outside.
It’s crispy on the outside, juicy and cheesy on the inside. Absolute perfection.
The whole thing comes together in about 30 minutes, which makes it a great way to get a mouthwatering dinner on the table fast.
Ingredients You’ll Need
This recipe keeps things super easy with just a handful of pantry staples.
You’ll need ground beef (80/20 is the way to go for those crispy edges), American cheese, flour tortillas, a white onion, butter, and a few basic seasonings.

That’s it! No fancy ingredients, no special equipment beyond a good cast iron skillet.
Tips for the Crispiest Smash Patties
The key to a great smash patty is a screaming hot skillet. You want it smoking before you even think about putting the beef down.
Use small balls of beef — about 2 ounces each — and smash them as flat as you can. The thinner the patty, the crispier those lacy edges get.
Don’t touch it once it’s down! Let it cook undisturbed for a solid 2-3 minutes so you get that incredible crust.

How to Assemble
Once your patties are done, reduce the heat to medium. Butter one side of a tortilla and lay it butter-side down in the skillet.
Stack two cheesy patties on one half, fold it over, and press gently. Cook for a couple minutes per side until you get that golden, crispy shell.
Let me tell you, that first bite with the cheese pull is out of this world.
Serving Suggestions
These smashburger quesadillas are incredible on their own, but a few extras really take them to the next level.
I love serving them with a side of crinkle-cut fries and a quick ketchup-mayo dipping sauce. Pickled jalapeños on the side are a must if you like a little heat.

You could also go with a simple side salad or some pickles to cut through the richness.
Variations to Try
Want to mix things up? Add some crumbled bacon inside for a bacon smashburger quesadilla. Phenomenal.
You could also throw in some pickles and a drizzle of special sauce for that classic fast-food vibe.
For a spicy kick, mix some sriracha into the cheese or add fresh jalapeños before folding. You can’t go wrong with any of these combos!
