Seitan Flares

These spicy seitan flares are a brilliant addition to any vegan barbecue or summer spread. By marinating the seitan in olive oil before grilling, you achieve a satisfyingly crisp texture that stands up beautifully to the bold, zesty glaze. The combination of fiery hot sauce, sweet maple syrup and fresh lime juice creates a complex flavour profile that offers the perfect balance of heat and tang.

This versatile plant-based dish works exceptionally well as a main course served with cooling celery sticks or as part of a larger grazing platter. It is a fantastic high-protein option for those seeking a substantial meat alternative that doesn't compromise on flavour. For the best results, use a high-quality aged cayenne pepper sauce to provide that classic, pungent kick.

Ingredients for Seitan Flares

  • 450g seitan, torn or cut into chunks large enough to fit loosely on the grill grate, or skewered

  • Extra-virgin olive oil

  • 60ml your favourite hot sauce, Frank's Red Hot Cayenne Pepper Sauce preferred

  • 45ml pure maple syrup

  • 60ml freshly squeezed lime juice

  • 1/2 teaspoons salt

  • Ground cayenne pepper (the more, the hotter!)

  • 2 tablespoons chopped fresh oregano (optional)

How to make Seitan Flares

Heat the grill to medium-high.

Prepare the seitan: Marinate the seitan in the olive oil to cover for 1 hour. Grill the seitan until lightly browned, 3 to 5 minutes or longer, turning often. Transfer to a bowl.

Meanwhile, make the sauce, if using: In a glass measure, whisk together the hot sauce, maple syrup, lime juice, salt, and cayenne pepper to taste. Microwave the mixture for 1 minute or until fairly hot, or whisk the mixture together in a small saucepan and place it over direct heat on the grill until it is hot, 4 to 5 minutes, or longer depending on the grill. Add the mixture to the seitan bowl and stir gently to combine, or coat the seitan if it is skewered. Finish with the optional oregano. Serve with extra sauce and celery sticks.
