Key Ingredients & Substitutions
Ground Beef: I recommend using 80/20 ground beef for a juicy burger. If you’re looking for a leaner option, 90/10 works, but you may miss some flavor. For a different twist, try ground turkey or plant-based beef alternatives.
Cheese: American cheese melts beautifully on burgers, but cheddar is a classic too! If you’re looking for something bolder, smoked gouda or pepper jack could add a nice kick. For dairy-free options, plant-based cheese can work well too.
Onions: Sweet or yellow onions are great for caramelizing. If you’re short on time, using pre-cooked sautéed onions can save you some hassle. Green onions can also add a fresh flair if you’re in a pinch.
Baconnaise Sauce: Mayonnaise is the base, but Greek yogurt makes a tangy, lighter alternative. If you’re not a bacon fan, try using a plant-based bacon or just skip it entirely for a simple mayo sauce with a bit of smoked paprika for flavor.
What’s the Best Way to Caramelize Onions?
Caramelizing onions might seem tricky, but it’s all about patience. The goal is to turn them golden and sweet, releasing their natural sugars. Here’s how to do it effectively:
- Heat your skillet on medium heat and add vegetable oil to prevent sticking.
- Add the sliced onions and a pinch of salt to help draw out moisture.
- Stir occasionally for about 10-15 minutes until they are golden brown. If they start to stick, lower the heat slightly.
- For depth, you can sprinkle a bit of sugar towards the end to enhance sweetness.
How to Make Smash Burgers with Baconnaise Sauce
Ingredients You’ll Need:
For the Burgers:
- 1 lb ground beef (80/20)
- 4 sesame seed hamburger buns
- 1 large onion, thinly sliced
- 4 slices cheese (American or cheddar)
- Salt and pepper, to taste
- Vegetable oil, for cooking

- 1 tablespoon Dijon mustard
- 1 tablespoon apple cider vinegar
- Pinch of smoked paprika
- Salt and pepper, to taste
How Much Time Will You Need?
This recipe will take about 25 minutes in total. You’ll spend around 10 minutes preparing the baconnaise sauce and cooking the onions, and about 15 minutes cooking the burgers and assembling everything. It’s a quick and flavorful meal that’s sure to delight!
Step-by-Step Instructions:
1. Prepare the Baconnaise Sauce:
Start by making the baconnaise sauce. In a medium bowl, mix together the mayonnaise, finely chopped cooked bacon, Dijon mustard, apple cider vinegar, and a pinch of smoked paprika. Stir everything until it’s well combined. Don’t forget to season with a little salt and pepper to taste. Cover the bowl and pop it in the fridge while you get on with the rest of the cooking. Letting it chill lets those delicious flavors blend together!
2. Cook the Onions:
Next, heat a skillet over medium heat and add a drizzle of vegetable oil. Toss in the thinly sliced onions. Cook them for about 10 to 15 minutes, stirring occasionally, until they are beautifully caramelized and golden brown. Once done, remove them from the heat and set aside.
3. Form and Smash the Patties:
Now it’s time to make the burgers! Divide the ground beef into 4 equal portions, which should be about 4 ounces each. Gently shape each portion into a loose ball. Heat a cast-iron skillet or griddle over high heat and add a splash of vegetable oil. Once it’s hot and shimmering, place one beef ball in the pan and smash it down with a spatula to create a thin patty. Season with salt and pepper. Let it cook for about 2-3 minutes until you see a nice crust forming on the bottom.
4. Flip the Patties:
Carefully flip each patty using a spatula. Right after flipping, place a slice of cheese on top of each patty. Cook for an additional 1-2 minutes until the cheese is melted and gooey. Yum!
5. Toast the Buns:
While the burgers finish cooking, slice the sesame seed buns in half. Toast them on another skillet until they’re golden brown. This step adds an extra crunch to your burgers!
6. Assemble the Burgers:
It’s assembly time! On the bottom half of each toasted bun, spread a good amount of your baconnaise sauce. Place a cheesy smashed patty on top, followed by a generous pile of the caramelized onions you cooked earlier. Finally, place the top half of the bun to complete the burger.
7. Serve:
Your smash burgers are ready to be devoured! Serve them warm alongside your favorite sides like crispy fries or a fresh salad. Enjoy every bite of this delicious creation!
Can I Use Ground Turkey Instead of Ground Beef?
Absolutely! Ground turkey can be a lean substitute for ground beef. Just keep in mind that turkey is less fatty, so you may want to add a bit of olive oil to the skillet while cooking to prevent drying out and to ensure a good sear.
How Can I Make the Baconnaise Sauce Spicier?
If you’d like to add some heat to your baconnaise sauce, try mixing in a dash of hot sauce or a pinch of cayenne pepper. You can also add finely chopped jalapeños for a fresh kick. Adjust to your spice preference for the perfect balance!
Can I Prepare the Onions Ahead of Time?
Yes! You can caramelize the onions in advance and store them in an airtight container in the fridge for up to 3 days. When you’re ready to use them, just reheat in a skillet over low heat until warmed through—this will enhance their sweetness!
What’s the Best Way to Store Leftover Burgers?
To store leftovers, let the burgers cool down, then place them in an airtight container in the fridge for up to 3 days. For best results, keep the patties and sauce separate from the buns to maintain their texture. Reheat in the microwave or skillet before serving!
