French Fry Po’ Boy – Air Fryer and Oven Directions

Traditionally a French Fry Po’ Boy is French fries sandwiched inside of a baguette and smothered with roast beef gravy. In this vegan po boy version, we season and bake the fries to get a crispy crust. We also make a mushroom gravy that adds extra umami to your new favorite sandwich. You’ll never miss the meat and I promise you that you won’t go hungry!

Where Did the French Fry Po’ Boy Come From?

New Orleans is known for its delicious food and it’s the home of the French Fry Po’ Boy Sandwich! 

This is another in my series of posts sponsored by the Idaho Potato Commission. I love potatoes and I know you do too!

What Exactly Is a Po’ Boy?

A Po Boy sandwich is a baguette filled with some kind of yummy filling, like these air fryer French fries. You can buy them by the 1/2 or whole, but most of the time even a 1/2 is huge in New Orleans.

Why Would You Put Gravy on a Sandwich?

With all that bread you need something saucy to keep your mouth from being dry.

The mushroom gravy here is in between a sauce and a gravy. I did it that way so it wouldn’t soak through the bread.

I hate soggy bread! You can choose not to reduce yours as much if you want to, or you could even just roast some mushrooms to put on your potato po’ boy.

What Does Getting My Sandwich Dressed Mean?

If you visit or live in New Orleans you’ll be asked if you want your po’ boy dressed. It means with lettuce, tomato, and mayo.

Personally, I like mine dressed with slices of ripe tomato, lettuce and a spread of vegan mayo. Top with a little Tabasco, Louisiana hot sauce, or Texas Pete to spice it up a little.

I actually put a few drops of hot sauce on each bite, so I have 

Skip the Bread and Just Make Fancy Fries!

Not in the mood for a sandwich? Make a plate of these fries, topped with gravy, hot sauce and melt a little vegan cheese. Yum!

Instructions

Oven Instructions:

• Preheat the oven to 425 degrees and prepare 2 baking sheets by spraying oil or covering with parchment paper.
• Put the potato planks into a soup pot and add water until it’s about 1 inch above the potatoes. Bring to a boil, then lower heat to medium and simmer for 4 minutes.
• Pour into a strainer over the sink and rinse with cold tap water to stop the cooking process.
• Add the drained potatoes to a large mixing bowl and carefully toss with the olive oil, Cajun seasoning, smoked paprika, salt, garlic, and black pepper. Arrange the fries on the baking sheets. Bake for 10 minutes, then take the sheets out and flip each fry.
• Bake on the second side for 10 more minutes. While the potatoes are baking heat 1 tablespoon olive oil in a large skillet over medium heat. Once hot add the mushrooms and saute until they begin to release their juices. Stir in the soy sauce and Worcestershire sauce and cook for 2 more minutes. Add the water and whisk in the tapioca starch. Turn the heat up to medium-high and cook until it thickens.
• Slice the bread in half lengthwise. Toast the bread if you’d like or cut into smaller sandwich pieces, slather vegan mayo and/or hot sauce on it or, serve it dressed with lettuce, tomato, and mayo. Layer the baked fries over the bottom piece of the bread and spread some of the mushroom mixture on top of the potatoes. Put the top piece of bread on and enjoy!

AirFryer Instructions:

• Place the cut fries in a heatproof bowl or saucepan. Heat up the water to a boil and then pour over the fries, covering them. I use my tea kettle, but you can even boil the water in a large saucepan and then add in the potatoes when you take it off the heat.
• Let the potatoes soak in the hot water for 15 minutes then pour into a strainer over the sink. Once mostly dry, toss the fries in the oil or aquafaba, Cajun seasoning, paprika, salt, garlic, and black pepper.
• Add the potato mixture to your air fryer basket and cook at 350 degrees for 5 minutes. Then shake the basket and cook 5 more minutes.
• Then raise the heat to 390 degrees and cook for 5 minutes, then shake the basket and cook a final 5 minutes more.
• Add the drained potatoes to a large mixing bowl and carefully toss with the olive oil, Cajun seasoning, smoked paprika, salt, garlic, and black pepper.
• While the potatoes are cooking, heat 1 tablespoon olive oil in a large skillet over medium heat. Once hot, add the mushrooms and saute until they begin to release their juices. Stir in the soy sauce and Worcestershire sauce and cook for 2 more minutes.
• Add the water and whisk in the tapioca starch. Turn the heat up to medium-high and cook until it thickens.
• Slice the bread in half lengthwise. Toast the bread if you’d like or cut into smaller sandwich pieces, slather vegan mayo and/or hot sauce on it or, serve it dressed with lettuce, tomato, and mayo.
• Layer the baked fries over the bottom piece of the bread and spread some of the mushroom mixture on top of the fries. Put the top piece of bread on and enjoy!
