Make a savory grilled cheese sandwich featuring homemade spring onion jam, melted Gruyère cheese, and bread spread with aromatic thyme butter.

Ingredients

Scale
  • 1 cup spring onions, white and green parts, thinly sliced
  • 1/4 cup apple cider vinegar
  • 2 tablespoons brown sugar
  • 1 tablespoon water
  • 1/4 teaspoon salt
  • Pinch of black pepper
  • 4 slices artisan bread
  • 4 ounces Gruyère cheese, shredded
  • 2 tablespoons unsalted butter, softened
  • 1/2 teaspoon fresh thyme leaves

Instructions

  1. To make the jam: Combine spring onions, vinegar, brown sugar, water, salt, and pepper in a small saucepan.
  2. Bring the mixture to a simmer over medium heat. Reduce heat to low and cook, stirring occasionally, for 25 to 30 minutes, until the liquid has reduced and the onions are soft and jam-like. Remove from heat and set aside to cool slightly.
  3. To make the thyme butter: In a small bowl, mix the softened butter with the fresh thyme leaves.
  4. Spread the thyme butter evenly on one side of each slice of bread.
  5. Assemble the sandwich: Place two slices of bread, butter-side down, in a non-stick skillet over medium-low heat.
  6. Top each slice with half of the Gruyère cheese, followed by a generous layer of the cooled spring onion jam.
  7. Place the remaining bread slices on top, butter-side up.
  8. Grill for 3 to 4 minutes per side, pressing gently with a spatula, until the bread is golden brown and the cheese is fully melted.
  9. Remove from the skillet, slice in half, and serve immediately.

Notes

  • For a sweeter jam, increase the brown sugar by one teaspoon.
  • If you do not have Gruyère, Swiss cheese or sharp white cheddar work well as substitutes.
  • Use low heat to cook the sandwich; this allows the cheese to melt completely before the bread burns.
