Vegan Po’ Boy Recipe

I like this recipe because the combination of flavors is downright irresistible. You’ll be transported to the heart of Louisiana, where the po’ boy sandwich was born, and where every bite is a celebration of bold, Southern flavors.

When shopping for ingredients, keep in mind that the choice of mushrooms can vary but varieties with meaty textures, such as shiitake or oyster mushrooms, work exceptionally well for this recipe.

And don’t skip the sauce! Homemade remoulade sauce takes this sandwich to the next level. Creamy and tangy, with just the right amount of zing, this sauce is a flavor powerhouse.

Additional traditional toppings may include crisp lettuce and juicy tomatoes. Pickles are another popular addition. Personally, I don’t care for them on the sandwich but do enjoy them on the side.

For the Remoulade Sauce:

• 1 1/2 cups cornmeal
• 1/4 cup all-purpose flour
• 1 tablespoon Creole seasoning

How to Make Mushroom Po’ Boys

For the Remoulade Sauce:

STEP ONE: In a medium bowl, whisk together the mayonnaise, dill relish, whole grain mustard, chili sauce, garlic, onion powder, and ground black pepper. Stir in the parsley and scallions. Adjust seasoning to taste then cover and refrigerate until ready to serve.

For the Mushrooms:

STEP TWO: In a medium bowl, whisk together the oat milk and lemon juice. Add the mushrooms and toss to coat. Set aside to marinate for 5 minutes. In a second medium bowl, combine the cornmeal, flour, Creole seasoning, and salt and set aside.

STEP THREE: In a large, deep skillet, heat the vegetable oil over medium-high heat to 350°F.

STEP FOUR: Working in batches, dip the wet mushrooms into the cornmeal mixture then into the hot oil. Fry for 2-3 minutes, until golden and crisp. Transfer to a paper towel-lined plate to drain excess oil from the mushrooms.

For the Po’ Boys:

STEP FIVE: Spread remoulade onto toasted sub rolls. Layer with shredded lettuce, fried mushrooms, and tomato slices, then serve.
