Grilled Blue Cheese Sandwiches with Walnuts and Watercress

These sophisticated grilled blue cheese sandwiches offer a refined twist on a classic toasted snack. The combination of salty blue cheese and earthy, toasted walnuts provides a wonderful depth of flavour, while the addition of fresh watercress adds a subtle peppery bite. Using wholemeal bread ensures a robust texture that stands up well to the richness of the melted cheese, creating a perfectly balanced vegetarian bite.

Ideal for a quick lunch or served as elegant canapés at a dinner party, these sandwiches are incredibly versatile. If you are entertaining, you can assemble the squares up to four hours in advance and keep them chilled until you are ready to fry. Serve them warm from the pan for a comforting, homemade treat that feels truly indulgent.

Ingredients for Grilled Blue Cheese Sandwiches with Walnuts and Watercress

  • 120g crumbled blue cheese (about 230g )

  • 80g finely chopped toasted walnuts

  • 16 slices whole wheat bread, trimmed into crustless 3-inch squares

  • 16 small watercress sprigs

  • 90ml (3/4 stick) butter

How to make Grilled Blue Cheese Sandwiches with Walnuts and Watercress

Divide cheese and walnuts equally among 8 bread squares. Top each with 2 watercress sprigs. Sprinkle with pepper and top with remaining bread squares, making 8 sandwiches total. Press together gently to adhere. (Can be made 4 hours ahead. Cover and chill.)

Melt 45ml butter in large nonstick griddle or skillet over medium heat. Cook 4 sandwiches on griddle until golden brown and cheese melts, about 3 minutes per side. Transfer to cutting board. Repeat with remaining 45ml butter and 4 sandwiches.

Cut sandwiches diagonally in half. Transfer to plates and serve.
