Ingredients You’ll Need
Here are a few notes on some of the key ingredients to make this smashburger sauce. Jump to the recipe card below for the exact measurements.
- Yellow onion: Grating the onions adds freshness and texture to the sauce. Sometimes we grill onions on the Blackstone before cooking burgers too!
- Condiments: Most are naturally gluten-free, but it’s always good to double-check labels. The main one you’ll need to look out for is the Worcestershire sauce. This article may help: “Is Worcestershire Sauce Gluten-Free?”
How to Make Smashburger Sauce

Grate some yellow onion and throw it in a small bowl with all of the condiments. Stir and enjoy, this sauce is as simple as that!
When I make smashburgers, I like to divide the sauce into two bowls. I use half on the burgers while they’re on the grill so that the sauce caramelizes straight into the patties. I use the other half when assembling the burgers before serving. This combo creates the most amazing flavor!

Question. Worcestershire sauce has gluten in it. I thought I clicked on a gluten-free site for smash burgers. What can be used instead?
Hi Bon, not all brands of Worcestershire sauce contain gluten. For example, the Lea & Perrins we use is labeled gluten-free. Here is an article with more information on gluten-free Worcestershire options. Hope this helps!
