Smash Burgers with Baconnaise Sauce 

Smash Burgers with Baconnaise Sauce 

These juicy smash burgers are loaded with crispy bacon, caramelized onions, melted cheese, and a creamy homemade baconnaise sauce. The combination of crispy-edged beef and a buttery toasted bun makes this an indulgent homemade burger worth making.

Ingredients

2 lbs fresh ground beef, preferably 80/20

2 sweet white onions, thinly sliced

½ lb thick-cut bacon

8 slices cheddar or American cheese

4 brioche burger buns

1 tablespoon butter

Salt and black pepper to taste

For the Baconnaise Sauce:

½ cup mayonnaise

3 tablespoons finely chopped cooked bacon

1 tablespoon bacon drippings

1 tablespoon Dijon mustard

1 teaspoon Worcestershire sauce

½ teaspoon garlic powder

¼ teaspoon black pepper

Preparation Steps

Cook the bacon in a large skillet until crispy. Transfer it to a paper towel-lined plate, reserving about 1 tablespoon of the bacon drippings.

Add the sliced onions to the skillet and cook over medium-low heat for 15–20 minutes, stirring occasionally, until deeply golden and caramelized.

Prepare the baconnaise by combining mayonnaise, finely chopped bacon, reserved bacon drippings, Dijon mustard, Worcestershire sauce, garlic powder, and black pepper. Refrigerate until ready to serve.

Divide the ground beef into 8 loose balls. Avoid packing the meat too tightly so the burgers stay tender.

Heat a cast-iron skillet or griddle over high heat. Place the beef balls onto the hot surface and immediately smash them into thin patties. Season with salt and pepper.

Cook for about 2 minutes until the bottoms develop dark, crispy edges. Flip the patties, top each with cheese, and cook for another 1–2 minutes.

Stack two cheesy patties for each burger. Add caramelized onions and crispy bacon.

Lightly butter and toast the brioche buns. Spread the baconnaise generously over both sides, then assemble the burgers and serve immediately.

Crispy beef, smoky bacon, melted cheese, sweet onions, and creamy baconnaise make every bite rich and satisfying. Wou
