Delicious Mushroom
You would think that it’s national mushroom week with two of my past three recipes being tied to mushrooms (Portobello ‘Shroom Burger & Fried King Oyster Mushroom Bites (Vegan)). Not to mention the one that’s coming today. But no, I just have major love for them! Be it as additions in soups and stews, or as its own main dish, mushrooms are simply sensational.
Crispy Fried Oyster Mushroom Burger
Oyster mushrooms in particular are known to have a more “meaty” and tender texture to it. Once breaded and fried, this crispy patty is often called as a vegan-friendly substitute to fried chicken. So naturally, I wanted to experiment incorporating it in one of my most-loved recipes: the Spicy Crispy Chicken Burger (inspired by KFC’s Zinger Burger!).
However, there are some slight adjustments to the seasonings and how I make the patty crispy. For this recipe, I bread the mushrooms by dredging it in the batter then coat it with panko crumbs.
Assemble the burger by placing the fried mushroom patty between toasted buns, alongside some lettuce, slices of cheese and tomatoes, and the spicy creamy sauce.
Make It Vegan
I used Kewpie mayo as one of the ingredients for the sauce. Swap it out with vegan mayo and use vegan cheese slices.

If you don’t want to assemble it into a burger, enjoy the crispy mushrooms on its own! They make for great appetizer bites, and can be scaled up for a crowd.

Notes for Spicy Crispy Mushroom Burger (Vegan-friendly)
- Cleaning the mushroom – Don’t let the mushrooms soak in water as they act like a sponge and will absorb the water. Instead, pat/wipe it with a damp paper towel.
- Burger sauce – The sauce is a mixture of Kewpie mayo/vegan mayo, sweet chili sauce, Sriracha, rice vinegar, light soy sauce, and chili flakes.
- Coat with batter fully – Make sure every inch of the oyster mushroom is covered with the batter otherwise the panko crumbs will not stick.
- Coat with panko – Make sure to really pack on the panko crumb so every inch of the mushroom is coated.
