Instructions

1
In a medium-hot frying pan, cook the ground beef, breaking it up with a spoon.

Season the beef with salt and pepper.

To make the sauce, combine mayonnaise, ketchup, relish, mustard, onion powder, and vinegar in a small bowl.

Whisk the sauce ingredients until smooth and well combined.

Using a rolling pin, flatten the top (sesame seed part) of a hamburger bun until it's thin.
7
Fold the flattened bun and place it in a taco holder to create a shell.
8
To assemble, add shredded iceberg lettuce to the bun shell, followed by a slice of American cheese.

Spoon the cheesy beef mixture on top of the cheese.
10
Top with pickle slices, a drizzle of the Big Mac sauce, and a sprinkle of finely chopped white onion.

Tips & Notes

Pro tips

Cook ground beef over medium heat until just browned; avoid overcooking, which dries it out and makes seasoning less flavorful.
Toast the flattened sesame seed bun in a hot skillet for 30–60 seconds to add crunch and prevent sogginess from the special sauce.
Mix the special sauce at least 15 minutes before serving to allow flavors to meld; taste and adjust mustard or vinegar balance to preference.
Assemble tacos immediately after warming the beef so the sauce doesn't soak into the shell.

Substitutions

Mayonnaise → Greek yogurt or sour cream (lighter, tangier result)
Sesame seed bun → soft hamburger bun or flour tortilla (easier to shape, less toasty flavor)
Cheddar cheese → American cheese or Swiss (melts faster or adds earthiness)
Relish → diced pickles or pickle juice (sharper tang, grainier texture)

Storage & make-ahead

Store seasoned beef and special sauce separately in airtight containers for up to 3 days. Reheat beef gently in a skillet and assemble fresh tacos before serving.

Common Questions

Can I make the special sauce ahead of time?

Yes, mix the mayo, ketchup, relish, mustard, and vinegar up to 3 days ahead. Store in an airtight container in the refrigerator.

What's the best way to flatten the sesame seed bun?

Use a skillet over medium heat or a panini press. Press gently for 30–60 seconds per side until it forms a taco-like shell without cracking.

How do I keep the beef seasoning from being too salty?

Add salt and black pepper gradually while cooking, tasting as you go. The special sauce adds additional flavor, so season the meat conservatively.

Can I use ground turkey or a plant-based alternative?

Yes. Use the same weight and cook until browned; plant-based versions may need slightly less time. Adjust seasoning to taste.

How should I store leftovers?

Store seasoned beef and special sauce separately in airtight containers for up to 3 days. Reheat beef gently in a skillet; assemble fresh tacos before serving to keep shells crispy.
