Ingredients Notes

Great burgers start with great ingredients, and this recipe keeps things simple but effective. Each component plays a crucial role in making these smash burgers unforgettable.

Ground beef – The key to a juicy smash burger is using 80/20 ground beef (that’s 80% lean meat and 20% fat). The higher fat content ensures a rich, flavorful patty that stays moist while cooking.

Brioche buns – Soft, slightly sweet brioche buns are the perfect match for these crispy-edged burgers. If you prefer a sturdier bun, potato rolls also work well. Just be sure to toast them for extra flavor and texture.

American cheese – While you can use any cheese, American cheese melts the best and gives that signature creamy, gooey texture. Cheddar, Swiss, or pepper jack are great alternatives if you want to mix things up.

Baconnaise sauce – This is where the magic happens. The sauce is a blend of crispy bacon, mayonnaise, Dijon mustard, smoked paprika, and a touch of garlic powder. It’s smoky, creamy, and just the right amount of tangy.

Pickles & onions – Thinly sliced onions and dill pickles add crunch and acidity, cutting through the richness of the burger and balancing out the flavors.

No special equipment is required, but a cast-iron skillet or a heavy-bottomed pan is essential to achieving the perfect sear on your burger patties.

How to Make This Smash Burgers with Baconnaise Sauce

Making these smash burgers is easier than you think, but a few key techniques make all the difference. Follow these steps for burger perfection.

Start by prepping the baconnaise sauce. Cook 4 slices of bacon until crispy, then finely chop them. In a small bowl, mix together ½ cup mayonnaise, 1 teaspoon Dijon mustard, ½ teaspoon smoked paprika, ¼ teaspoon garlic powder, and the chopped bacon. Stir until well combined and set aside.

Next, prepare your burger patties. Divide 1 pound of ground beef into four equal portions, but don’t roll them into tight balls—keep them loose. This helps with the “smash” effect and creates the perfect crispy edges.

Heat a cast-iron skillet over high heat for about 2 minutes until it’s very hot. While the pan is heating, butter the brioche buns and toast them in the skillet for about 30 seconds until golden brown. Set aside.

Place one portion of ground beef in the skillet and immediately press it down with a spatula (or use a burger press) to flatten it into a thin patty. Hold the press for about 10 seconds to ensure good contact with the pan. Season with salt and black pepper.

Let the patty cook undisturbed for 2 minutes. Once the edges are crispy and dark brown, flip the patty, add a slice of American cheese, and cook for another 30-45 seconds until melted. Repeat with the remaining patties.

To assemble, spread baconnaise sauce on both sides of the toasted brioche buns. Place the burger patty on the bottom bun, top with pickles and onions, and close with the top bun. Serve immediately and enjoy!

Storage Options

While smash burgers are best enjoyed fresh, you can still store leftovers properly to enjoy them later.

If you have leftover cooked patties, store them in an airtight container in the fridge for up to 3 days. Reheat them in a skillet over medium heat for about 2 minutes per side. Avoid the microwave, as it can make the patties rubbery.

Baconnaise sauce can be made ahead of time and stored in the refrigerator for up to 5 days in an airtight container. This makes it a great prep-ahead option for quick meals throughout the week.

If you want to freeze the patties, wrap them individually in plastic wrap and place them in a freezer-safe bag. They’ll keep for up to 3 months. Thaw in the fridge overnight before reheating.

Variations and Substitutions

One of the best things about smash burgers is how versatile they are. Here are some fun ways to change things up:

Spicy Smash Burgers – Add ½ teaspoon cayenne pepper to the beef mixture and use pepper jack cheese instead of American for a fiery kick.

BBQ Bacon Smash Burgers – Mix 1 tablespoon of BBQ sauce into the baconnaise for a smoky-sweet twist, and top the burger with crispy onion rings.

Mushroom Swiss Smash Burgers – Sauté mushrooms in butter and garlic until golden brown, then use Swiss cheese instead of American for a rich, savory upgrade.

Keto-Friendly Smash Burgers – Swap the brioche buns for lettuce wraps or low-carb burger buns, and make sure your baconnaise sauce is sugar-free.

Turkey Smash Burgers – Use ground turkey instead of beef for a leaner option. Just be sure to add a little olive oil to the mix to keep the patties from drying out.

No matter which variation you choose, don’t be afraid to experiment. That’s the beauty of homemade burgers—you can make them exactly the way you like!

These Smash Burgers with Baconnaise Sauce are everything a burger should be—crispy, juicy, and packed with flavor. Whether you’re making them for a family dinner or a casual backyard gathering, they’re guaranteed to be a hit.
