Equipment

  • cast iron skillet or deep fryer

Ingredients

  • ½ - 1 pound oyster mushrooms note 1

Wet Batter

  • 1 cup full fat can coconut milk , unsweetened note 2
  • 1 tablespoon apple cider vinegar
  • 2 teaspoons cajun seasoning mix note 3
  • ¼ teaspoon sea salt
  • ¼ teaspoon black pepper

Dry Batter

For Sandwich

Instructions

  • Take a damp paper towel and begin to wipe down your oyster mushrooms (this is how you clean mushrooms). If you rinse them instead, be sure to pat them dry with a paper towel. Set aside to begin making your batter.
  • Start with the wet batter. Add coconut milk, apple cider vinegar, cajun seasoning mix, sea salt, and black pepper to a large bowl and mix together. Add oyster mushrooms to the wet batter and allow it to marinate for 10 minutes.
  • In a separate mixing bowl, add white spelt flour, baking powder, cajun seasoning mix, sea salt, and black pepper to a large bowl and mix together. Set aside.
  • In the meantime, grab your cast-iron skillet and add enough oil for frying leaving about an inch or so of room from the at the top of the skillet. (The amount will vary depending on the vessel you are using to fry. For a deep fryer I tend to use the entire bottle of oil. For my cast iron skillet, I use ¾ of a 24-ounce bottle of oil).
  • Turn heat on high and heat oil for 2 - 3 minutes until it is hot. If you have thermometer, it should read between 350°F (175°C) - 400°F (200°C). I don't use a thermometer so how I test my oil is by dipping a small piece of battered oyster mushroom in the oil. If it sizzles, that means it's ready.
  • Take your marinated mushrooms and dip them in to your dry batter fully coating. I like to do this one at a time to make sure they are fully coated in the dry flour mixture. However, you can add multiple pieces in your dry batter at a time. Begin to add these pieces to your oil to begin frying.
  • Fry in batches adding a few pieces at a time being sure not to over crowd the mushrooms. Fry for 2 to 3 minutes until evenly brown and crispy. Once mushrooms are done frying remove from skillet with a fry strainer and place them on a paper towel to drain the excess oil off. Repeat until all mushrooms are cooked.
  • Begin to assemble your sandwich. To your french bread add your vegan remoulade sauce, lettuce, tomatoes, pickles, and fried oyster mushrooms. Serve with a salad or as is! Fried oyster mushrooms will keep in the refrigerator for 2-3 days. DO NOT freeze.

Notes

  1. MUSHROOMS: You can try this recipe with other types of mushrooms. I like oyster mushrooms because they have an awesome texture. But you can try it with king oyster mushrooms or portobello and see how that works!
  2. COCONUT MILK: I like use full fat coconut milk in a can because of it's thickness. I find it coats the mushrooms better very similar to a buttermilk texture. But any unsweetened plant based milk you desire like my homemade Hemp Sea Moss Milk recipe!
  3. CAJUN SEASONING MIX: This is a homemade recipe very simple to make. However if you don't feel like whipping up your own you can use a store bought mix.
  4. WHITE SPELT FLOUR: Regular spelt flour will work for this recipe or just any all purpose flour. If you are gluten free, the ONLY gluten free flour I recommend is chickpea flour. In my experience, this flour works well for frying. If you try any other gluten free flour, do so at your own risk. 
  5. BAKING POWDER: The baking powder (NOT BAKING SODA!!!) gives the crust a "light an airy" crispness (along with the apple cider vinegar). I wouldn't omit it. You can however substitute apple cider vinegar with lime or lemon juice.
  6. VEGETABLE OIL: Any vegetable oil with a very high smoke point will work. There is NO SUCH THING as a healthy oil to fry with as deep frying is not a healthy way of cooking. Therefore all purpose vegetable oil, corn oil grape seed oil, or even canola oil will work. 
  7. ADDITIONS & SUBSTITUTIONS: Some Po’ Boy Recipes use cornmeal in there batter when frying. I didn’t for this recipe but you surely can if you prefer it that way. You can try this recipe with other types of mushrooms if you like. (I only use oyster mushrooms). 
  8. AIR FRYER: I tried this recipe in an air fryer and it didn't turn out as crispy as with the traditional way of frying. However the flavor and taste was still there. So if you want to try it in your air fryer give it ago! I air fried it at at temperature of 350°F (175°C) for about 7 minutes in batches until all the pieces were cooked.
