Honey-sweetened made-from-scratch onion jam is the linchpin of these tasty turkey and cheese sandwiches. To keep these savories from being too tall, we removed and discarded a 1⁄4-inch cross-section from each roll before decorating the tops with sesame seeds in an X pattern.

Turkey–Onion Jam Sandwiches
Serves: 12
Ingredients
- 1 tablespoon unsalted butter
- 1 small yellow onion, diced 1⁄4-inch
- 2 tablespoons honey
- 2 tablespoons white wine vinegar
- 2 tablespoons whole-grain mustard
- 2 sprigs fresh thyme
- 1 bay leaf
- 1⁄2 teaspoon kosher salt
- 12 butter rolls*
- 3 tablespoons mayonnaise
- 6 ounces thinly sliced deli turkey
- 2 ounces thinly sliced Gruyère cheese
- 1⁄2 cup white sesame seeds
- 1 large egg white
- 1⁄4 cup baby arugula
Instructions
- In a medium sauté pan, heat butter over medium heat. Add onions and cook, stirring occasionally, until golden brown, 15 to 20 minutes. Reduce heat to medium-low. Stir in honey, vinegar, mustard, thyme, bay leaf, and salt. Cook, stirring occasionally, until liquid is mostly reduced and onions are sticky, 7 to 10 minutes. Remove from heat and let cool to room temperature. Remove and discard herbs.
- Preheat oven to 350°. Line a rimmed baking sheet with parchment paper.
- Trim rolls down to equal sizes and split each roll in half horizontally. If desired, remove a 1⁄4-inch cross section from each roll. Spread mayonnaise onto cut side of bottom halves of rolls and place on prepared baking sheet. Top each with a layer of turkey and of cheese, trimming as need to fit roll bottoms.
- Bake until cheese melts, 3 to 5 minutes.
- Spoon a layer of onion mixture onto cheese.
- Place sesame seeds in a small bowl. Using a pastry brush, paint egg white onto top halves of rolls in an X shape. Dip roll top in sesame seeds, gently pressing to adhere. Using a toothpick, tidy edges of sesame seed X. Place a roll top half, sesame side up, on onion mixture layer.
- Bake until lightly toasted and egg white dries, 2 to 3 minutes.
- Just before serving, remove tops and add a few leaves of arugula to each sandwich. Serve warm or at room temperature.
