Prepare the Big Mac Sauce. In a medium bowl, whisk together mayonnaise, relish, mustard, paprika, sugar, onion powder, Worcestershire sauce, garlic powder, salt, and pepper. Refrigerate until ready to use.
Rehydrate the onions. Mix the minced dried onion with the water and set aside.
Form the patties. Divide the ground beef into 8 portions and shape into thin patties. Season with salt and pepper.
Cook the patties. In a large skillet over medium-high heat, cook 4 patties at a time, flipping once, until cooked through (about 2 minutes per side). Set aside on a paper towel-lined tray and repeat with the remaining patties.
Drain the onions. Scoop the rehydrated onions out of the water and place them on a paper towel-lined plate.
Toast the buns. Melt butter in a large skillet over medium-high heat. Lightly toast all the buns and set aside.
Assemble the burgers. Start with the bottom bun and spread on Big Mac sauce. Add cheese, lettuce, pickles, a patty, and onions. Top with another bottom bun, more sauce, lettuce, pickles, a patty, onions, and finally the top bun. Repeat with remaining burgers and serve!
Notes
Tips, Tricks & Storage
Use Bottom Buns for the Middle Layer Authentic Big Macs use an extra bottom bun in the middle to soak up the sauce without falling apart.Thin Patties Are Key Keep the burgers thin so they cook quickly and stack nicely without overwhelming the sandwich. Since patties shrink as they cook, make them slightly larger than the buns to start. For perfectly round patties, roll the meat into a ball and press it with a jar lid before cooking.Toasting Makes a Difference Buttering and toasting both the bottom and top bun pieces adds great texture and keeps the sandwich from getting soggy.Drain the Onions Well Soaking dried onions brings out their flavor, but drain them well before adding to avoid excess moisture.Let the Sauce Chill The sauce tastes best after resting in the fridge for a few hours or overnight. This helps the flavors blend and deepen. And when assembling the burgers—don’t be shy! That Big Mac sauce ties the whole thing together.Storage Keep cooked patties and extra sauce in separate airtight containers in the fridge for up to 3 days. Patties can also be frozen (unassembled) for up to 3 months. Thaw in the fridge, then reheat in a skillet or air fryer before serving. The Big Mac sauce can be made up to 5 days in advance—its flavor actually improves as it sits. If it separates, just stir it back together.If you prep parts of the meal ahead, assemble the burgers just before serving to keep the buns crisp. *Pro tip* Extra sauce is amazing on fries, tacos, wraps, or even as salad dressing.
Variations
One of the best things about this recipe is how flexible it is.Not into pickles? Prefer lettuce wraps instead of buns? Go for it. You can skip or swap ingredients as you like. If you’re extra hungry, add another patty and a slice of cheese for a Double Mac Melt. If you’re looking for something lighter, you can also use ground turkey or chicken for a leaner version. Mix sriracha, hot sauce, or chipotle powder into the sauce for a bold flavor boost. Expecting a crowd? Make Mini Mac Sliders using slider buns and smaller patties for a party-friendly twist. SubstitutionsMissing something or trying to work with what’s in your fridge? Here are some easy swaps that still deliver great results.Sweet Pickle Relish → Dill Relish or Bread-and-Butter Pickles Dill relish gives a tangier, saltier flavor, while bread-and-butter pickles add mild sweetness. Either keeps the sauce tasting balanced and classic.Minced Dried Onion → Fresh Finely Chopped Onion Fresh white or yellow onion works perfectly if lightly sautéed to mellow its bite. You can also soak raw onion slices in water for 30 minutes to soften their flavor before adding them in.American Cheese → Cheddar, Colby, or Monterey Jack Any good melting cheese will work. Cheddar adds a sharp bite, while Colby and Monterey Jack stay smooth and creamy.80/20 Ground Beef → Any Ground Beef Blend A higher fat blend gives juicier burgers, while leaner beef creates a lighter, firmer patty. Choose based on your preference.Sesame Buns → Plain Hamburger Buns or Brioche Rolls No sesame buns? No problem. Plain or brioche rolls work well—just toast them to keep structure and add a bit of crunch.
