Mushroom Po’ Boys

Hi All!

I can’t believe my last post was 2 months ago. This is my first one for 2017! Between the holidays, home renovations, getting a bad cold and getting swamped with work, I just didn’t have an opportunity to make anything that I was excited about posting. I hope this recipe makes up for the hiatus.

Po’ Boys are Louisiana style sandwiches on soft rolls or baguettes that are usually filled with meat or seafood and dressed with tomatoes, lettuce, pickles and mayo.ย I thought that a mixture of oyster and shiitake mushrooms were a great protein substitute, because they have a delicate, yet meaty flavour. After they are fried up, they visually look very similar to fried oyster or shrimp. I also made a spicy horseradish mayo to bring in a bit of heat.


  • Vegetable Oil (for frying)
  • 2 French roll or sub/hoagie buns, sliced almost fully legnth wise
  • 2 tbsp butter
  • 1 cup green lettuce (boston bib, iceberg, romaine)
  • 1 Tomato, sliced
  • 1 red onion, thinly sliced
  • dill pickles
  • 1 egg (optional – helps to bind)
  • 1 cup milk (substitute: plain soy milk)
  • 1 cup all purpose flour
  • 1 cup cornmeal
  • 1/4 tsp cayenne powder
  • 1/4 tsp paprika
  • 1/4 tsp dried oregano
  • 1/4 tsp onion powder
  • 1/4 tsp garlic powder
  • 1/2 tsp salt
  • pinch of ground black pepper
  • 1 cup oyster mushrooms
  • 1 cup shiitake mushrooms
  • 1/2 cup mayonnaise (substitute: vegannaise)
  • 1 tsp ground horseradish
  • tobasco sauce to taste (I used approx 1 tsp)
  • zest from 1 lemon
  1. Heat up oil to 300F
  2. In a bowl, mix together egg, milk, flour, cayenne, paprika, dried oregano, onion powder, garlic powder, salt and black pepper (place cornmeal in a spare plate or bowl). Coat each mushroom in wet mixture, then coat in the cornmeal.
  3. Fry mushrooms until golden and crispy
  4. In a bowl, mix together mayonnaise, horseradish, tobasco and lemon zest.
  5. Butter each bun and add lettuce, tomatoes, onion, pickles, spicy horseradish mayo and fried mushrooms. Slice in half and enjoy ๐Ÿ™‚

    Now this looks like an absolutely wonderful sandwich. I’ve eaten a few sandwiches in my day, and I can tell you right now that this sandwich tastes great. I personally only eat American sandwiches, but not because I wouldn’t try a sandwich from another country, but simply because it’s all I can get from Helen’s Diner and trust me Helen isn’t gonna make anything else. But I sure would love to try this sandwich one day. Maybe I’ll just decide to make it myself! Fat chance!


  2. Rhonda, you are a very special woman.
