When you need a burger in your life, make it epic. Our Bacon Onion Smash Burger has smoked onions, bacon-wrapped smoked onions, double-smoked bacon, melted sharp cheddar, and two smashed wagyu beef patties. All of that gets sandwiched between a toasted onion bun!
Bacon Onion Smash Burgers
Smash burgers are the ultimate summer bbq meal, and these ones take them to a whole new level. We make burgers all the time here. Our kids love them, they are super easy to make for unlimited numbers of people, and pretty much everyone loves a good burger.
Smash burgers are especially quick and easy since they go onto a blazing hot gas griddle before being smashed super thin. They cook really quickly, have a great crust, and you can make about 20 at a time on even a mid-sized griddle.

How to make Bacon Onion Smash Burgers
This is just the overview so you can see what you’re actually getting into here. When you are cooking, you’ll want to use the full recipe at the bottom of the page.
Wrap and smoke the onions
Wrap your onion slices with the thin-sliced bacon. Preheat your smoker to 225°, and place the wrapped onions directly on the grill grates. Smoke for 30 minutes, flip, and continue smoking at 225° for another 20ish minutes until the bacon is cooked. It’ll crisp a little when it cools, so don’t overcook!
Smoke or griddle the thick-cut bacon
Double-smoke your bacon or cook it on the griddle. Whatever you prefer. Our Traeger No-Flip Bacon is a great option!
Form the meatballs and preheat the griddle
Form 8 equal balls with your meat. Season the top sides. Preheat your griddle over medium-high heat.
Put your burgers seasoning-side-down on the griddle and use a piece of parchment paper between the meat and your smasher to prevent sticking, and then smash the burgers down onto the griddle. Season the side facing up when you have smashed all the burgers.
Flip and cheese
Flip the burgers once, top with cheese, and cover (if you have a griddle cover, use that. If you have a dome cover, use that.)
Toast those buns and serve
Toast the buns on the griddle and start loading up your burgers.
What should you serve with Smash Burgers?
We like to serve fries with burgers when we have them around. You can hit the easy button and make Frozen Fries on the griddle. If you don’t have frozen fries around and have an air fryer, our Homemade Air Fryer French Fries are amazing!
Bacon Onion Smash Burgers FAQ
Are the smoked bacon-wrapped onions really required?
Nooooo. I guess not. But they make this burger a LOT better!
What if I don’t like smash burgers?
You do you! If you prefer smoked burgers, make those. Like griddle burgers that aren’t smashed? Do your thing!
