Ingredients

For the Smash Burgers:

1 lb ground beef (80/20 lean-to-fat ratio recommended)
4 burger buns
4 slices cheddar cheese
1 tablespoon olive oil
Salt and black pepper to taste

For the Baconnaise Sauce:

½ cup mayonnaise
1 tablespoon ketchup
1 teaspoon yellow mustard
1 teaspoon garlic powder
1 teaspoon onion powder
4 strips cooked bacon, crumbled

Step-by-Step Instructions

Step 1: Prepare the Baconnaise Sauce

In a medium bowl, combine the mayonnaise, ketchup, mustard, garlic powder, and onion powder. Mix well until smooth. Stir in the crumbled bacon and mix thoroughly.

Cover and refrigerate for at least 15–30 minutes to allow the flavors to blend together. This resting time enhances the smoky, creamy, slightly tangy taste of the sauce.

Pro Tip: For extra smokiness, add ½ teaspoon smoked paprika or a splash of barbecue sauce.

Step 2: Prepare the Beef

Divide the ground beef into 4 equal portions (about 4 ounces each). Gently shape them into loose balls. Do not overwork the meat — keeping it loose ensures a tender burger.

Do not season the beef yet. Smash burgers are seasoned directly on the griddle for maximum flavor.

Step 3: Heat the Pan or Griddle

Heat a cast iron skillet or flat griddle over high heat for several minutes until extremely hot. This high heat is essential for creating the crispy crust.

Add olive oil and spread it evenly.

Step 4: Smash the Burgers

Place one beef ball onto the hot surface. Let it sit for about 5–10 seconds.

Using a sturdy spatula (or a burger press), firmly press down on the beef until it becomes thin and flat (about ¼ inch thick).

Immediately season with salt and pepper.

Cook for 2–3 minutes without touching it. This allows the Maillard reaction to create that deep brown, crispy crust.

Flip the burger carefully. Immediately place a slice of cheddar cheese on top. Cook for another 1–2 minutes until the cheese melts and the burger is cooked through.

Repeat with remaining beef balls.

Step 5: Toast the Buns

Slice the burger buns and place them cut-side down on the hot skillet for 1–2 minutes until lightly golden. Toasting prevents the buns from becoming soggy and adds extra flavor.

Assembling the Smash Burgers

Spread a generous amount of baconnaise sauce on the bottom bun.
Place the cheesy smash burger patty on top.
Add an extra spoonful of sauce if desired.
Cover with the top bun.
Serve immediately while hot.

Optional Toppings

You can customize your smash burger with:

Lettuce
Tomato slices
Pickles
Caramelized onions
Jalapeños
Extra crispy bacon

Cooking Tips for the Best Smash Burgers

Use 80/20 ground beef for the best balance of flavor and juiciness.
Do not press the burger after flipping — only smash once at the beginning.
Cook on very high heat for a proper crust.
Use cast iron for best results.
Serve immediately for maximum juiciness.

What Makes Smash Burgers Different?

Unlike traditional thick burgers, smash burgers are pressed thin onto a hot surface. This increases surface contact, creating more browning and flavor. The crispy edges combined with the juicy interior create the perfect texture contrast.

Storage and Reheating

Store leftover patties in an airtight container in the refrigerator for up to 3 days.
Reheat in a hot skillet for best texture.
Avoid microwaving if possible to maintain crispiness.
