Epic Vegetarian Burger

Mushrooms, caramelised onions, kidney beans and smoked cheese make this patty so full of flavour!



  • For the Patty:
  • 1 onion, finely chopped
  • Olive oil
  • Butter
  • 10 small to medium sized mushrooms
  • Salt and pepper
  • 1/2 tsp ground coriander
  • 1 tsp ground paprika
  • 1 can drained red kidney beans
  • 1/2 cup breadcrumbs or 1-2 slices of stale bread
  • Smoked cheese (to taste, use less if it is a strong flavour)
  • Mozzarella cheese (to melt on the patties at the end)
  • Lettuce for serving
  • For the Salsa:
  • 2 slices of pineapple rings
  • 4 small, pickled gherkins
  • 1 tomato
  • Salt and pepper
  • For the Garlic Mayonnaise:
  • 2-3 cloves of garlic, minced
  • 4 tbsp mayonnaise


  1. Add the chopped onion to pan on a medium low heat with olive oil and butter and caramelise until golden brown, 10-15 minutes.
  2. In a food processor, pulse the mushrooms, salt and pepper, coriander, paprika, and the caramelised onions, until you have a course pate texture.
  3. Add drained beans, pulse, then add the breadcrumbs/stale bread and pulse until well combined. Stir through some smoked cheese of your choice. Check the taste is good before proceeding, adjust as required.
  4. Turn out onto a greased baking tray, then with oiled hands, form the mixture into 4 patties.
  5. Bake at 180°C for 25 minutes.
  6. Make a quick salsa by mixing finely chopped tomatoes, gherkins, and pineapple. Season with salt and pepper to taste.
  7. Stir the minced garlic through some of your favourite mayonnaise.
  8. Take the patties from the oven, cover them in mozzarella cheese, then put back in the oven with your cut buns until the cheese is melted, about 5 mins.
  9. To serve, spread garlic mayo on the bottom bun, then top with lettuce, bean patty, salsa, garlic mayo on your top bun, then done! I've served mine with a side of hot chips.
  10. Om nom nom nom nom nom nom! Enjoy!

  • When it comes to burgers I thought it wasn’t possible to display the words „epic“ and „vegetarian“ in one sentence without a „not“ inbetween. But this looks actually really epic!

    • You're welcome! Though if you try it and want it vegan, remember to change out the mayo, butter and cheese for vegan alternatives 🙂
