Sandwichs Espresso Recipe

Make espresso reduction

Combine the cooled espresso, brown sugar, and balsamic vinegar in a small saucepan. Bring to a gentle simmer over medium-low heat and reduce until slightly thickened and syrupy, about 6–8 minutes. Stir occasionally. Remove from heat and let cool to warm; the reduction will further thicken as it cools.

Prep bread and spreads

Split the ciabatta rolls horizontally and lightly toast cut sides under a broiler or in a skillet until just golden (about 1–2 minutes). Mix the softened butter with a pinch of salt and spread half on the cut sides that will be toasted. In a small bowl combine mayonnaise and Dijon mustard; set aside.

Brush or drizzle about 1 teaspoon olive oil over the bottom half of each warmed roll. Layer the sliced roast beef or smoked turkey evenly over the bottom half (about 60 g per sandwich if making two).

Spoon about 1 tablespoon of the espresso reduction over the meat, distributing it evenly. Taste a small amount first — the coffee reduction should add a savory-sweet, slightly acidic note; adjust amount if you prefer milder coffee flavor.

Top the meat with one slice of provolone or fontina. If you prefer melted cheese, place the assembled bottom halves briefly under a broiler (about 1–2 minutes) or in a covered skillet over low heat until the cheese begins to melt.

Scatter the thinly sliced red onion over the cheese (about 1 tablespoon) and add tomato slices if using. Season veggies lightly with 1/8 teaspoon kosher salt and a pinch of freshly ground black pepper.

Add a generous handful (about 1/2 cup per sandwich) of arugula on top of the vegetables. Drizzle 1/2 teaspoon of the espresso reduction over the arugula to tie flavors together.

Spread the mayonnaise-Dijon mixture on the top half of each roll (about 1 tablespoon), then place the top half over the sandwich. Press gently to compact.

If desired, melt 1 teaspoon butter in a skillet over medium-low heat and toast the assembled sandwiches, pressing down with a spatula, until golden and warmed through, about 2–3 minutes per side. Alternatively, serve as-is at warm temperature.

Cut the sandwich in half on the diagonal. Serve immediately while cheese is warm and espresso notes are fresh. Offer extra espresso reduction on the side for drizzling.
