20-Minute Big Mac Smash Tacos
Big Mac Smash Tacos take everything you love about the drive-thru classic and tuck it into a crispy tortilla with a seared smash burger patty. Tangy special sauce, melty cheese, crisp lettuce, and those pickles all show up in a handheld taco that comes together in about 20 minutes.
It is all the nostalgia without the drive-thru, and they are faster than you would guess. If you like smash burgers and you like tacos, this recipe is for you.
Why These Smash Tacos Work
The contrast between the crispy, seared beef and the warm soft tortilla is what makes these so good. Smashing the patty right onto the tortilla on the griddle fuses them together, so you get caramelized edges while the inside stays tender.
The special sauce is a quick stir of pantry staples, and it tastes so close to the real thing you might never bother with a drive-thru again. These are a hit with kids and adults alike, and they feel like a treat without any complicated steps.
Ingredients
- 1/2 cup mayonnaise: the base for that creamy, tangy sauce
- 2 tbsp ketchup: adds sweetness and color
- 1 tbsp sweet pickle relish: the key to the signature Big Mac flavor
- 1 tsp white vinegar: a little sharpness to cut through the richness
- 1/2 tsp onion powder: for savory depth
- 1/2 tsp garlic powder: rounds out the spice blend
- 1/2 tsp paprika: adds a subtle smokiness
- Pinch of salt
- 1 lb 80/20 ground beef: divided into 8 equal portions (about 2 oz each); the higher fat content keeps the patties juicy
- 8 small flour tortillas: street taco size, roughly 4 to 5 inches across
- 4 slices American cheese: halved, so you get one half per taco
- 1 cup finely shredded iceberg lettuce: the classic cool crunch
- 1/4 cup finely diced white onion: use a sharp onion for a little bite
- 16 dill pickle slices: 2 per taco is just right
- 2 tsp toasted sesame seeds: optional, for that iconic sesame seed bun nod
Variations / Substitutions
- Swap the protein: ground turkey or chicken work, but you will lose some of the juicy fat and crisp edges. Cook turkey a minute longer to be safe.
- Use corn tortillas: warm them slightly first so they are pliable and less likely to crack when folded.
- Cheese alternatives: mild cheddar or Colby Jack melt nearly as well as American and still give that creamy pull.
- Dairy-free option: use a good vegan mayo in the sauce and skip the cheese, or try a plant-based American style slice.
- This sauce is also great on a Smash Burger served in a bun.
How to Make Big Mac Smash Tacos
Step 1: Whisk the Special Sauce
In a small bowl, whisk together the 1/2 cup mayonnaise, 2 tablespoons ketchup, 1 tablespoon relish, 1 teaspoon vinegar, 1/2 teaspoon onion powder, 1/2 teaspoon garlic powder, 1/2 teaspoon paprika, and a pinch of salt. Set the sauce aside while you cook the beef.
Step 2: Smash and Sear the Patties
Preheat a large nonstick skillet or griddle over medium-high heat. Place a tortilla flat in the pan and drop a 2-ounce portion of beef in the center. Using a sturdy spatula or burger press, smash the beef firmly until it spreads almost to the edges of the tortilla, about 4 inches across. Cook for 2 minutes, until the edges look lacy and deep golden brown. Flip the tortilla so the patty is now on top, then immediately lay half a slice of cheese over the beef. Cook another 1 to 2 minutes, just until the cheese melts and the tortilla is crisp in spots. Repeat with the remaining tortillas and beef, working in batches so the pan stays hot.
Step 3: Top and Fold the Tacos
Move each hot taco to a plate. Spoon about a tablespoon of the sauce over the cheese, then pile on a small handful of shredded lettuce, a sprinkle of diced onion, and two pickle slices. Scatter a few sesame seeds on top if you are using them, fold the tortilla around the fillings, and serve right away while everything is hot and the tortilla is still crisp.
A Few Notes Before You Start
- Press the beef as thin as you can without tearing the tortilla. The thinner the patty, the more lacy, caramelized edges you get.
- Give your pan time to heat up properly. A too cool surface steams the meat instead of searing it, and you lose that crispy crust.
- Work in batches of two or three tacos at a time. Overcrowding drops the pan temperature and makes them harder to flip cleanly.
- If you like extra sauce, double that batch right from the start. It keeps well in the fridge and you will want more than you think.
What to Serve With Big Mac Smash Tacos
These tacos are a meal on their own, but a side of crispy oven fries or onion rings rounds them out nicely. A simple shredded slaw with a vinegar based dressing cuts through the richness of the beef and creamy sauce without weighing things down.
Frequently Asked Questions
Can I make the special sauce ahead of time?
Yes, and it tastes even better after a few hours. Store it in a sealed container in the fridge for up to a week.
What is the best cheese substitute for American?
Mild cheddar or Colby Jack both melt smoothly and give a similar creamy texture without overpowering the other flavors.
Can I double this recipe easily?
Yes, just cook in batches and keep finished tacos warm in a low oven while you work through the rest of the beef and tortillas.
Can I cook these on an outdoor griddle?
Absolutely. A Blackstone or any large flat griddle works great because you can cook several at once over even high heat.
