🔪Prep Time: 15 minutes

👩‍🍳Cook Time: 20 minutes


Portobello Burgers:

4 Portobello Mushrooms Stems Removed

1/2 Tbsp Grapeseed Oil


1/4 cup Soy Sauce (60ml)

1 tsp Paprika

2 Tbsp Maple Syrup

1 Tbsp Light Brown Sugar

2 Tbsp Tomato Paste

1/8 tsp Liquid Smoke

1/2 tsp Oregano

Caramelized Onions:

1/2 Tbsp Olive Oil

1 Medium Onion White, Yellow or Brown, Chopped

1 Tbsp Soy Sauce

2 Tbsp Maple Syrup


Hamburger Rolls



Dill Pickles



1Remove the stems from the portobello mushrooms.

2Prepare your marinade by adding soy sauce, paprika, maple syrup, brown sugar, tomato paste, liquid smoke and oregano to a measuring jug. Whisk together until well mixed.

3Place the mushrooms on a baking tray or in a shallow dish and brush generously with the marinade on both sides. Leave them to soak in the marinade for 15 minutes.

4While the mushrooms are marinating, make your caramelized onions. Add chopped onions and olive oil to a frying pan and sauté until the onions are softened.

5Add soy sauce and maple syrup and sauté with the onions until sticky and caramelized.

6Heat up a grill pan and then brush it with 1/2 tablespoon of high smoke oil (we used grapeseed oil).

7Add the mushrooms and fry for around 3 minutes each side at medium heat.

8Then turn off the heat and brush both sides with marinade.

9Serve the portobello burgers on hamburger rolls with lettuce, sliced tomato and sliced dill pickles and topped with the caramelized onions and sliced avocado.
