What Are Smash Burgers?

Smash burgers are made by pressing a ball of ground beef onto a hot skillet or griddle, “smashing” it down to create a thin patty. This process allows for maximum contact with the heat, developing that signature crispy, golden-brown crust known as the Maillard reaction — a flavor explosion of caramelized beef goodness.

Unlike thick patties that rely on internal juiciness, smash burgers get their flavor from that crispy exterior and perfectly melted cheese.

The Secret Ingredient: Baconnaise Sauce

Let’s talk about the show-stealer — baconnaise. It’s exactly what it sounds like: bacon + mayonnaise = magic.

This sauce is creamy, smoky, slightly tangy, and absolutely addictive. It’s made from crispy bacon blended with mayo, garlic, Dijon mustard, and a hint of lemon juice. Use it as a spread for burgers, sandwiches, or even a dip for fries. Once you’ve tried it, you’ll never go back to plain mayo again.

Ingredients

For the Smash Burgers:

• 1 ½ lbs ground beef (80/20 blend for best flavor)
• 1 tsp kosher salt
• ½ tsp black pepper
• 1 tbsp butter or neutral oil (for skillet)
• 4 slices cheddar cheese (or American cheese)
• 4 brioche buns, toasted
• 1 small onion, thinly sliced (optional)

For the Baconnaise Sauce:

• 6 slices bacon
• ½ cup mayonnaise
• 1 tsp Dijon mustard
• 1 clove garlic, minced
• 1 tsp lemon juice
• ¼ tsp smoked paprika
• Salt and pepper, to taste

Toppings:

• Crisp lettuce leaves
• Sliced tomatoes
• Pickles
• Extra bacon (optional, but highly encouraged)

Instructions

1. Cook the Bacon
Start by frying your bacon in a skillet over medium heat until perfectly crisp. Transfer to a paper towel–lined plate to drain. Reserve 1 tablespoon of bacon fat for the baconnaise.

2. Make the Baconnaise Sauce
In a food processor, combine the cooked bacon, mayonnaise, Dijon mustard, garlic, lemon juice, smoked paprika, and a spoonful of reserved bacon fat. Blend until smooth and creamy. Adjust salt and pepper to taste. Chill in the fridge while preparing the burgers.

3. Form the Burger Patties
Divide the ground beef into 8 small balls (about 3 ounces each). Do not overwork the meat — this helps keep the texture loose and juicy.

4. Smash the Burgers
Heat a cast-iron skillet or griddle over high heat until smoking hot. Add a bit of butter or oil. Place two or three beef balls on the skillet and smash them immediately using a heavy spatula or burger press. Flatten to about ¼ inch thick.

Season with salt and pepper and cook for 2 minutes until the edges are crispy and browned. Flip once, add a slice of cheese, and cook for another minute.

5. Toast the Buns
While the burgers cook, lightly butter and toast the brioche buns on the skillet until golden and crisp.

6. Assemble the Smash Burgers
Spread a generous layer of baconnaise on both sides of the buns. Add lettuce, tomato, and pickles to the bottom bun, followed by one or two cheesy burger patties. Top with crispy bacon and more baconnaise if you’re feeling bold.

Finish with the top bun and press down slightly to let all that goodness meld together.

Tips for Perfect Smash Burgers

• Use high-fat beef (80/20): The fat ensures juiciness and rich flavor.
• Don’t pre-form the patties: Keep them as loose balls until they hit the skillet.
• Smash immediately: Press down within 10 seconds of contact to create a crust.
• Don’t move the patty: Let it sear undisturbed for maximum browning.
• Melt cheese fast: Cover the skillet briefly with a lid to melt cheese evenly.

Serving Suggestions

Smash burgers are perfect with sides that complement their richness. Try pairing them with:

• Crispy French fries or sweet potato fries
• Onion rings for extra crunch
• Coleslaw for a refreshing contrast
• Grilled corn on the cob during summer barbecues

You can also serve mini versions of these as sliders for game days or parties.

Variations to Try

• Spicy Smash Burgers: Add jalapeños and spicy mayo instead of baconnaise.
• BBQ Smash Burgers: Replace baconnaise with smoky barbecue sauce and top with crispy onions.
• Double Cheese Lovers: Layer cheddar and Swiss cheese for a rich melt.
• Turkey Smash Burgers: Use ground turkey for a lighter option and still enjoy the baconnaise flavor.

Fun Fact: The Origin of Smash Burgers

The “smash” technique became popular in American diners in the mid-20th century. It was discovered that pressing burgers on a hot griddle not only cooked them faster but also intensified the flavor. This method was later popularized by chains like “Smashburger,” but the magic of homemade versions lies in the control — you get to decide how crispy, cheesy, and saucy your burger gets.

Make-Ahead and Storage Tips

• Baconnaise Sauce: Can be stored in the refrigerator for up to 5 days.
• Burger Patties: Form the beef balls and refrigerate up to 24 hours before cooking.
• Cooked Burgers: Store in an airtight container for up to 3 days; reheat on a skillet.
