Grilled Mushroom and Caramelised Onion-Filled Beer Can Burgers


Grilled Mushroom and Caramelised Onion-Filled Beer Can Burgers

When I found this recipe for these amazing beer can burgers I just knew I had to give them a try. And I wasn’t disappointed – they were amazing!

Shaped around a beer can to form a cavity, these burgers are filled with grilled mushrooms and homemade caramelised onions, then topped with cheese and baked in the oven or barbecue. And because all the toppings are in the burger, you only need hamburger buns and fresh salad leaves to serve!

Here’s what you’ll need to make this crowd-pleasing summer barbecue favourite.


For the hamburger patties – beef mince, breadcrumbs, an egg and hamburger seasoning. For the caramelised onions – two red onions, butter, red wine vinegar and caster sugar.  You’ll also need some mushrooms and grated cheese, as well as bacon, thyme, bread rolls, lettuce and seasonings (not pictured).

First, make your fillings. The caramelised onions were by far the most time consuming part of the recipe so feel free to skip this step and use ready made from a jar if you like. I don’t think it would make that much of a difference to be honest, but they certainly were yummy made from scratch.

Then combine your hamburger ingredients together and divide into four. Shape each quarter around a beer can to form a little bowl.


Wrap a rasher of bacon around the meat and gently remove the can. Drink it if you like!

Half fill the cavity with your grilled mushrooms…


… then top with your caramelised onions and a little thyme. I used dried thyme, didn’t matter.


Top with some grated tasty cheese and place onto a baking tray.


Bake in an oven or covered barbecue (not on direct heat, we’re baking, not frying) for 45 minutes and serve on the buns with mixed salad leaves and enjoy!

Other variations of this meal you could try are:

  • lamb mince with feta, olives and char-grilled capsicum
  • chicken mince with sundried tomatoes and wilted baby spinach
  • beef mince with grilled onions and an egg cracked into the centre with cheese on top
