Smash Burgers with Creamy Baconnaise Sauce: The Ultimate Comfort Food

by

Few foods scream indulgent comfort like a juicy, crispy-edged smash burger. Add to that a silky, smoky baconnaise sauce (yes, bacon + mayonnaise = heaven), and you’ve got a burger experience that borders on the divine. Smash burgers are all about simplicity—meat, heat, and technique—while baconnaise elevates the whole dish with a creamy, tangy, bacon-packed punch that feels gourmet yet approachable.

In this recipe article, we’ll dive deep into the magic of smash burgers, explore the origins of baconnaise, and walk step by step through creating this perfect pairing. By the end, you’ll have not just a recipe, but the know-how to craft smash burgers that rival the best burger joints.

Why Smash Burgers?

Unlike thick pub-style burgers, smash burgers are thin patties seared hard against a hot griddle or cast-iron pan. The smashing process maximizes the Maillard reaction—that delicious golden-brown crust you get when proteins and sugars caramelize at high heat. The result is a burger that’s crispy on the outside, juicy inside, and utterly irresistible.

Paired with melted cheese, soft buns, and a decadent sauce, smash burgers deliver fast-food nostalgia with gourmet flair.

What Is Baconnaise?

Baconnaise is simply mayonnaise infused with crispy bacon and a few flavor boosters. It’s creamy, smoky, salty, and slightly tangy—perfect for spreading onto burger buns or dipping fries. While you can buy versions in stores, nothing compares to homemade baconnaise made from scratch with fresh, crunchy bacon.

For this recipe, we’ll make a creamy baconnaise sauce that’s not just mayo and bacon but also enhanced with garlic, mustard, and a touch of lemon for brightness.

Ingredients

For the Smash Burgers:

  • 1 ½ pounds (680 g) ground beef (80/20 lean-to-fat ratio is ideal for juiciness)

  • Kosher salt and freshly cracked black pepper

  • 4 slices American cheese (or cheddar, if you prefer sharper flavor)

  • 4 soft burger buns, lightly toasted (potato buns or brioche work beautifully)

  • Optional toppings: shredded lettuce, pickles, sliced onions, or tomatoes

For the Creamy Baconnaise Sauce:

  • 6 strips thick-cut bacon

  • ½ cup mayonnaise (use a good-quality or homemade mayo)

  • 1 teaspoon Dijon mustard

  • ½ teaspoon garlic powder

  • ½ teaspoon smoked paprika (optional, for extra smokiness)

  • 1 teaspoon lemon juice (for tang)

  • Salt and pepper, to taste

For Serving:

  • Crispy fries, onion rings, or even a side salad

Step-by-Step Instructions

Step 1: Make the Baconnaise Sauce

  1. Cook the bacon in a skillet over medium heat until crispy. Drain on paper towels, reserving about 1 tablespoon of bacon fat.

  2. Finely chop or crumble the crispy bacon.

  3. In a mixing bowl, whisk together mayonnaise, Dijon mustard, garlic powder, smoked paprika, lemon juice, and a spoonful of bacon fat.

  4. Stir in the chopped bacon. Taste and adjust seasoning with salt and pepper.

  5. Refrigerate for at least 15 minutes to let flavors meld.

👉 This sauce keeps for up to 5 days in the fridge.

Step 2: Prep the Beef Patties

  • Divide the ground beef into 4 equal portions (about 5–6 ounces each).

  • Roll them gently into balls—do not compact too tightly. The looser the pack, the better the smash.

  • Keep chilled until ready to cook.

Step 3: Toast the Buns

  • Lightly butter or brush buns with bacon fat.

  • Toast them cut-side down on a hot skillet until golden brown.

  • Set aside.

Step 4: Smash the Burgers

  1. Preheat a cast-iron skillet or griddle over high heat until smoking hot.

  2. Place one beef ball onto the skillet. Using a flat metal spatula (or burger press), smash firmly until the patty is very thin (about ¼-inch thick).

  3. Season immediately with salt and pepper.

  4. Cook for 2 minutes until edges are brown and crispy.

  5. Flip, add a slice of cheese, and cook another 1 minute until cheese is melted.

  6. Repeat with remaining patties.

👉 Pro tip: For extra indulgence, you can double-stack patties on each bun.

Step 5: Assemble the Burger

  1. Spread creamy baconnaise sauce generously on both the top and bottom buns.

  2. Place the cheesy smash burger patty (or patties) on the bun.

  3. Add toppings like lettuce, onions, pickles, or tomatoes, if desired.

  4. Crown with the top bun and serve hot.

Tips for Success

  1. Use the Right Beef: An 80/20 beef blend ensures juiciness. Too lean, and your patties will dry out.

  2. Don’t Overwork the Meat: Handle the beef as little as possible—overworking makes it tough.

  3. Smash Only Once: Press down hard at the beginning, but don’t keep pressing or flipping. This preserves the juices.

  4. Double Smash = Double Flavor: Many burger joints stack two thin patties per burger for maximum crust and juiciness.

  5. Customize Baconnaise: Add hot sauce, honey, or even roasted garlic for different flavor twists.

  6. Serve Immediately: Smash burgers are best enjoyed fresh and hot, as the thin patties can dry quickly.
