About this Recipe

This recipe is inspired by the “Cheese Toastie” at London’s Borough Market. One of my colleagues gave me the recipe a few years ago. It’s simply the best grilled cheese I’ve ever tasted. Three different cheeses give complex, funky flavor, but the real secret is the inclusion of 3 different alliums. Red onion, leek and garlic add sweetness and a pungent bite that pairs nicely with the rich cheeses. A thin layer of mayonnaise on the outside helps the sandwich crisp to perfection. Don’t skip the softened butter on the inside - it’s a key component of the flavor! This sandwich is best made with large slices of high-quality sourdough bread, but you’ll only be able to fit 2 sandwiches on the tray. We recommend using square sliced sourdough sandwich bread if you want to make 3 or 4 sandwiches.


  • ¼ cup chopped leeks (½-inch pieces) (about ¼ of a small leek)
  • ¼ cup chopped red onion (½-inch pieces) (about ¼ of a large red onion)
  • 1 clove garlic, minced
  • 1 oz english cheddar, grated
  • 1 oz Gruyère, grated
  • 1 oz fontina, grated
  • 2 large slices sourdough bread
  • Mayonaise
  • Butter at room temperature
