Today is National Sandwich Day! That's right, a day to celebrate the ultimate convenience food.

From the plain ham on white bread to fancy ciabattas with all types of artisan delights, the humble sandwich is something we all take for granted and yet, love.

In paying respect to our favorite meal, we turned to the Guinness Storehouse, Ireland’s number one tourist attraction, who are spreading their love with some Guinness-inspired recipes.

Straight from the Storehouse’s Executive Chef, Justin O’Connor, here’s a recipe for a bookmaker sandwich with Guinness onion marmalade.

Steak with Guinness onion marmalade sandwich recipe 


  • 2 x 100g trimmed beef sirloin steaks
  • 2 large slices of buttered sliced soda bread
  • ½ beef tomato sliced
  • ¼ red onion cut into rings
  • 5 leaves of baby gem lettuce
  • Optional - Sauce Choron (Hollandaise with tomato puree)


Quickly fry the sirloin steaks on each side and season.

Assemble by placing on warm toasted soda bread, and place tomato on top, followed by red onion and baby gem lettuce.

Place some of the onion marmalade on the other soda bread slice and top of the sandwich.

Serve with Guinness onion marmalade and potato wedges.
