Step‑by‑Step Instructions for Smash Burgers with Baconnaise Sauce
Step 1: Prepare the Burger Balls
Start by taking the ground chuck and carefully forming it into 1/3 pound balls. Arrange them on a plate or a baking sheet and refrigerate for 30 minutes. This chilling process helps the patties hold their shape and enhances the juiciness in your Smash Burgers with Baconnaise Sauce.
Step 2: Slice the Onions
Using a mandoline, thinly slice the white onions to achieve uniform, paper-thin slices. Once sliced, squeeze out any excess moisture with a clean kitchen towel and transfer them to a plate. Refrigerating the onions while you prepare the burgers sharpens their flavor and keeps them crisp.
Step 3: Cook the Bacon
In a skillet over medium heat, cook the bacon until crispy, which should take about 6-8 minutes. Once done, transfer the bacon to a paper towel-lined plate to drain any excess fat, then chop it into small pieces and set aside. This crunchy bacon will be essential in both the burgers and the smoky baconnaise sauce.
Step 4: Make the Baconnaise Sauce
In a medium bowl, combine the mayo, ketchup, mustard, crispy chopped bacon, Worcestershire sauce, apple cider vinegar, all-purpose rub, and red pepper flakes. Stir well to create a creamy, smoky baconnaise sauce. Cover and refrigerate for at least 15 minutes to let the flavors meld, enhancing your burgers when assembled.
Step 5: Preheat the Griddle
Heat a griddle over medium-high heat for about 5 minutes, until it’s hot but not smoking. Drizzle a bit of avocado oil to coat the surface evenly. This high-temperature cooking is essential for that perfect, crispy crust on your Smash Burgers with Baconnaise Sauce.
Step 6: Cook the Burger Balls
Place the chilled burger balls spaced apart on the hot griddle. Allow them to sear for about 2-3 minutes without moving them. As they cook, the edges will begin to caramelize and develop a golden-brown crust, which adds incredible flavor to your burgers.
Step 7: Smash the Burgers
Once the burger balls have a nice sear, take a spatula or burger press and firmly smash each ball into a flat patty. Sprinkle salt, pepper, and garlic on top for added flavor. Cook for another 2-3 minutes to allow the juices to escape and create that signature smash burger texture.
Step 8: Add Mustard and Cheese
After about 3-4 minutes of cooking, drizzle mustard on top of each smashed patty, then carefully flip them over. Immediately place a slice of pepper jack cheese on each patty to melt for an additional 3 minutes. The cheese should melt beautifully, offering a creamy layer to your burger.
Step 9: Toast the Buns
While the burgers finish cooking, arrange the burger buns cut-side down on the griddle. Toast them for about 1-2 minutes until they are golden brown and slightly crispy. This adds a delicious crunch and keeps the buns from getting soggy with the fillings.
Step 10: Assemble the Burgers
To put together your mouthwatering Smash Burgers with Baconnaise Sauce, start with a toasted bottom bun and spread a generous layer of baconnaise sauce. Place a cheesy patty on top, then add more baconnaise sauce and finish with the top bun. Serve immediately and revel in the juicy flavors!

Smash Burgers with Baconnaise Sauce Recipe FAQs
How do I choose the best ground chuck for my burgers?
Absolutely! When selecting ground chuck, look for meat with an 80/20 fat content, as this provides optimal flavor and juiciness. The meat should appear bright red, without any dark spots. If possible, ask your butcher to grind it fresh for the ultimate taste!
How should I store leftover Smash Burgers?
For sure! Store any leftover Smash Burgers in an airtight container in the fridge for up to 3 days. It’s best to separate the patties from the baconnaise sauce to maintain freshness. If you want to keep them longer, freezing is the way to go!
Can these burgers be frozen?
Absolutely! You can freeze cooked Smash Burgers for up to 3 months. First, wrap each patty tightly in plastic wrap, then place them in a freezer-safe ziplock bag to prevent freezer burn. When you’re ready to enjoy, simply thaw in the fridge overnight and reheat in a skillet.
What if my burgers don’t have that crispy exterior?
Don’t worry! If your burgers aren’t achieving that crispy crust, ensure your griddle is preheated properly. It should be hot enough to sizzle when you place the patties on it. Also, avoid moving them too soon—allow them to sear for about 3-4 minutes before smashing.
Is there a substitute for bacon in the baconnaise sauce?
Very much so! If you want a lighter option or need a bacon alternative, consider using crispy turkey bacon or omitting it entirely for a vegetarian version using plant-based patties. Just adjust the flavors in your baconnaise with additional smoked paprika for that smoky depth!
Can I make baconnaise sauce in advance?
Absolutely! I often prepare the baconnaise sauce a day ahead to enhance the flavor profiles. Just combine all the ingredients and store in a sealed container in the fridge for up to 1 week. Give it a good stir before using to mix those lovely flavors back together!
