Vegetarian Smash Burger with Fried Egg and Avocado

Smash burgers are trendy right now. You smash the patty with a spatula while it cooks. I like doing it because it cooks faster and makes the patty a bit more crispy.

I’m quite picky when it comes to preparing and eating my burger. I don’t just throw the ingredients together in a random order, there is some thought behind it. In this post I share with you how I make a vegetarian smash burger at home.

I used a Laugen bun for this recipe, which is basically a German soft pretzel in bun form. The deep brown colour comes from the lye bath the buns get before baking, which gives them that classic pretzel look. I like the buns to be toasted so the sauce doesn’t soak in too much. It keeps them from getting soggy and adds a bit of texture.

I bought a plant-based patty from the brand Beyond Meat. The patty should be stacked as close to the bottom bun as possible. It’s easier to eat that way and gives a better mouthfeel when everything else is stacked on top.

When building the burger, I prefer melting the cheese directly on the patty instead of adding it cold. Then I add pickled onions or pickles, or whatever is in the fridge. Once the top bun is on, I stick a skewer through to keep it all together. This time I used a regular round wooden skewer, but the short squared ones are even better for stability.

Hope you enjoy it as much as I do.
