Grilled Skirt Steak and Pepper Sandwiches with Corn Mayonnaise

These grilled skirt steak and pepper sandwiches offer a sophisticated twist on the classic steak sarnie. This high-protein dish combines tender, charred beef with smoky grilled vegetables and a vibrant, herb-flecked corn mayonnaise. Using skirt steak is an excellent choice for outdoor grilling, as it takes on a beautiful char while remaining juicy, especially when paired with the sweetness of fire-roasted red peppers and onions.

Perfect for a weekend lunch or a protein-rich midweek dinner, this recipe balances rich flavours with fresh garden herbs like oregano and basil. The addition of crunchy sweetcorn to the mayonnaise provides a delightful texture that complements the crusty ciabatta or baguette. It is an impressive yet simple meal for anyone looking to elevate their homemade sandwich game with fresh, seasonal ingredients.

Ingredients for Grilled Skirt Steak and Pepper Sandwiches with Corn Mayonnaise

  • 160ml mayonnaise

  • 1 1/2 tablespoons red wine vinegar

  • 1 tablespoon chopped fresh oregano

  • 1 tablespoon chopped fresh basil

  • 1 small garlic clove, pressed

  • 6 4-inch-long baguette sections or one 450g loaf ciabatta, halved horizontally

  • 2 ears of corn, husked

  • 2 small red peppers, quartered lengthwise

  • 1 large red onion, cut into 1/3-inch rounds

  • 1 1/4 to 675g skirt steak, cut crosswise into 6-inch pieces

  • Olive oil (for brushing)

Prepare barbecue (high heat). Whisk first 5 ingredients in medium bowl. Set aside. Pull out some of inside of bread, forming thick shells. Brush corn, peppers, onion, cut sides of bread, and steaks with olive oil. Sprinkle with salt and pepper. Grill vegetables until charred and just tender and steaks until charred and cooked to medium-rare, about 15 minutes for corn, 8 to 10 minutes for peppers, and 5 to 8 minutes for onion, turning occasionally, and 3 minutes per side for steaks. Let steaks rest 5 minutes. Grill bread, cut side down, until charred, about 2 to 3 minutes.

Cut corn from cobs; add 240ml to bowl with mayonnaise mixture and stir to coat. Season to taste with salt and pepper.

Cut steaks diagonally against the grain into 1/3- to 1/2-inch-thick strips. Arrange steak slices, peppers, and onion over bottom halves of bread. Spoon corn mayonnaise over. Top with bread, pressing slightly to compact. (If using ciabatta, cut into 6 sandwiches.) only 377 calories!
