Have fun with your vegetables! These snack-able and stackable fries are easy to eat and make an impressive presentation.

Technique tip: Do your frying in a pot much larger than you think you'll need to avoid any hot oil spilling over the sides.

Swap option: You can use almost any other vegetable for these fries. It's especially good with asparagus.


  • Soy dipping sauce

    • 1/2 teaspoon soy sauce
    • 1½ tablespoon sweet soy sauce (Ketjap Manis)
    • 1/2 teaspoon Thai fish sauce
    • 3 tablespoons mirin
    • 1 teaspoon rice wine vinegar
    • 1 slice fresh ginger, smashed
  • Portobello fries

    • 5 cups canola oil
    • 8 portobello mushrooms, stems and gills removed
    • 2 cups all-purpose flour, divided
    • 2 cups club soda
    • 2 large eggs
    • 1 teaspoon kosher salt
    • Sea salt


For the soy dipping sauce:

Mix all the ingredients together and let marinate covered in the refrigerator overnight. Strain and set aside until ready to serve.

For the Portobello fries:

1. Heat the canola oil in a large pot to 325°F.

2. Cut the mushrooms into think strips, about 1/2-inch thick, like steak fries.

3. Lightly dust the mushrooms with 2 tablespoons of the flour.

4. In a bowl, mix together the flour, club soda, eggs and salt to form a batter.

5. Dip the portobello fries in the batter.

6. Cook the fries in for about a minute. Remove and drain on a paper towel-lined plate and let cool.

7. Increase the heat to bring the oil to 375°F.

8. Cook the fries again at the higher until they are golden brown and crispy. Remove and drain on a paper towel-lined plate. Season the fries with sea salt and serve with soy dipping sauce.
