Ingredients

For the smoked onion mayo:

  • ½ pound hickory chips
  • 2 yellow onions, julienned
  • 1 teaspoon, plus ½ teaspoon salt
  • 1 teaspoon sugar
  • ½ teaspoon oil
  • 1 teaspoon Worcestershire sauce
  • ½ tablespoon hot sauce, preferably Crystal
  • ¼ teaspoon ground coriander
  • 2 ½ cups mayonnaise

For the blackened avocado:

  • 2 ripe avocados
  • ½ cup Creole seasoning
  • 2 tablespoons canola oil               
  • 2 tablespoons apple cider vinegar           
  • 1 tablespoon red onion, small dice          
  • 1 tablespoon tomatoes, small dice

For the po’boy:

  • 12 medium shrimp, peeled & deveined
  • 1 tablespoon Creole seasoning
  • Four 7-inch pieces Leidenheimer po’boy bread
  • 2 ounces smoked onion mayo (see above)                         
  • 1/3 cup blackened avocado (see above)
  • 3 tomato slices 
  • ¼ cup shaved Romaine lettuce   

Directions

For the smoked onion mayo:

Soak hickory chips in water. While the chips are soaking toss the onions in 1 teaspoon salt and sugar. Then place the chips in a preheated grill or smoker and hard smoke for 30 minutes. Once onions are smoked, caramelize them over medium-low heat in a large pan with the oil until nice and dark golden brown. Purée caramelized onions with Worcestershire, hot sauce, coriander, and remaining ½ teaspoon of salt. Then fold onion purée into mayonnaise. Taste for seasoning.         

For the blackened avocado:

Place a cast-iron pan over high heat. Cut avocados in half and remove stone and then remove the peel. Coat avocado halves in Creole seasoning.  Place oil in cast iron pan and then blacken avocados on both sides. Remove from pan, allow to cool slightly, and then dice into 1-inch pieces and lightly toss with vinegar, red onion, and tomato.           

For the po’boy:

Sprinkle the shrimp in Creole seasoning and grill on each side for 1 minute. Cooking time may vary depending on your heat. Divide the shrimp between the bread, add the mayo, avocado, tomato slices, and lettuce. Serve and enjoy. 

Grilled Shrimp Shopping Tip

It may be tempting to buy peeled, deveined shrimp, but if you're going to be grilling them, you'll get juicier shrimp if you leave the shell on.

Grilled Shrimp Cooking Tip

Make sure to thoroughly rinse and dry the shrimp before cooking them.
