I tasted these amazing eggplant mushroom vegetarian burger with brioche bun in one of the local bakery for breakfast. It is located in the city , and we had to travel to city to dine in.I forgot the cafe’s name but the burger is amazing even eating cold. I believed it is a pop up store. Both husband and I tasted it and wondered how to replicate it. I hope you can also try vegetarian burger with different flavour.

  2. Marinade egg plant slice with soybean paste, sugar and 1 tbsp cooking oil to well coated. Arrange every slice eggplant onto prepared baking tray, and bake at top oven rack for 30 minutes until slightly charred and cooked through. Remember to flip all eggplant slice half way cooking for achieving both side charred. Remove the grilled eggplant from oven to allow to cool down, then store in refrigerator for an hour.
  3. In a non-stick saucepan:Heat 1 tbsp cooking oil, saute the chopped onion until soften, then add in the mushroom. Saute until cooked, season with salt and pepper to your taste. Transfer to a clean plate, allow to cool down fully.Then store in refrigerator for an hour .
  4. Take out the cooled mushroom, take a small handful of mushroom, hold tight in our palm to squeeze out extra juices to form a patty shape.
  5. On other side, on your chopping board, arrange cooked eggplant in a particular order like shown in the picture. Place the mushroom patty onto the eggplant, and fold the eggplant to cover all the mushroom. Gently hold the egg plant patty on your both palms and shape into a nice patty shape, and coat entire patty with enough plain flour. Wrap with cling film and secure it tightly.
  6. Repeat step 4 and 5 for the rest of the patties. You will get 4 patties altogether. Allow to chill in freezer for 1-2 hours until hardened.
  7. Remove the hardened patties from freezer and unwrap altogether. Coat each patties with beaten egg, then with the japanese breadcrumb. You can repeat this coating process once again,(it is called double coatings).

  • You can use other types of eggplant such as the classic and regular eggplant also named as Black Beauty or black bell pepper. I am using chinese eggplant that is longer and cylindrical in shape.

For more information on varieties of eggplant:

  • The reason to freeze your eggplant patties before final coating because the patties are so soft with the mushroom and eggplant, secondly there is no other ingredients act as adhesive agent such as potato mash. So we need to make sure it is hardened in freezer for easier coating and deep frying.
  • This meat-free vegetarian burger supposed to serve as cold sandwich, but if you preferred crunchy patties and super soft brioche, slightly toast your brioche burger on hot pan for just less than 30 seconds on medium-high heat,otherwise might burn your brioche due to the high content of milk and butter used in this recipe. The bread is super soft after toast, so be gentle when handling brioche burger in hot pan.
  • you can use  any favourite vegetables such as lettuce, tomato, cucumber or even beetroot slice for the burger.

How to make ring molds for the burger:

There burger bun dough is pretty soft, and it cannot remain the shape after proofing and baking. Therefore,to avoid this  and to keep the buns round as burger shape, it is advisable to bake in ring molds.If you have these exact ring molds, feel free to use it. Otherwise, here is how to make our DIY ring molds with few tools.

1)Get a piece of used A4 size paper,fold in 36cm length  x 1 cm width on the longest side of the paper 3 times to get a strip.

2)Then place into a slightly bigger rectangular aluminium foil and make 3 foldings to make a long strip.

3)Make a diameter of 10cm ring from the strip by joining 2 ends together, then staple it down.Repeat this for 9 more ring molds.

8. Line baking paper on tray, and place in all the ring molds.Lightly spray some cooking oil around the ring molds.


9. Divide dough into 10 balls(roughly 80g per portion) by cutting out with scissors or using a scraper to cut the dough for much easier task, then roll into round and smooth balls.

10. Once all buns are formed, transfer quickly to the prepared pan , placing each bun in the center of each ring molds. Keep everything loosely covered with damp towel.Lightly flatten the buns into burger bun shapes.

11. Allow the buns to proof in a warm room(I did this in my oven, roughly 25C)  to double in size for about 2 hours.


12. Before baking, prepare the egg wash.Brush the egg wash onto each buns nicely, then sprinkle with some white and black sesame seeds.

13. Bake the buns at preheated oven of 175C for 15-18 minutes , depending on individual oven.

14. Once brioche is done or reach golden brown colour, transfer the tray of brioche out of the oven to a cooling rack. Allow to cool down completely before remove from the ring molds to retain the shape.

15. You can serve fresh brioche with just butter and jam, or with any fillings you like.


  • Once all buns are formed, burst any air bubbles that have formed. Spray lightly with oil and flatten them slightly to make a burger bun shape.
  • For better results: To increase the humidity of the oven especially during cold weather,you can place a pan of hot water under the trays of brioche dough when first  put into the oven, allow the buns to expand to fill up the ring molds , then remove the water from oven to finish off the baking.
  • You can store brioche in a container for 2 days at room temperature,some said it can turn the brioche bun to a softer texture.You can store the baked brioche in freezer too up to 1 month.Bring  the frozen buns to room temperature if needed and pan fry with some oil for crispy bun or without oil at all.
  • These buttery brioche can be served cold too as cold sandwich.
