Print Recipe

This isn’t just a way to use up Thanksgiving leftovers — it’s a properly built sandwich with layers of juicy turkey, melted Gruyère, crisp apple, and a tangy mustard aioli, all pressed until golden and shatteringly crisp. The combination of sweet, savory, and sharp flavors makes it feel like a deliberate meal, not a leftover afterthought. Ready in about 20 minutes, it’s the best thing to happen to turkey since the main event.

Ingredients

Scale
  • For the mustard aioli:
  • 1/2 cup mayonnaise
  • 2 tablespoons Dijon mustard
  • 1 teaspoon fresh lemon juice
  • 1 small garlic clove, grated or finely minced
  • 1/4 teaspoon kosher salt
  • 1/4 teaspoon freshly ground black pepper
  • For the sandwich:
  • 8 slices rustic sourdough bread, cut 1/2-inch thick
  • 3 tablespoons unsalted butter, softened
  • 12 ounces cooked turkey breast, sliced 1/4-inch thick
  • 1 large tart apple (such as Granny Smith or Honeycrisp), cored and sliced 1/8-inch thick
  • 6 ounces Gruyère cheese, coarsely grated (about 1 1/2 cups)
  • 1 1/2 cups fresh arugula or baby spinach, loosely packed
  • 2 tablespoons extra-virgin olive oil, for brushing the pan

Instructions

  1. Make the mustard aioli: In a small bowl, whisk together the mayonnaise, Dijon mustard, lemon juice, grated garlic, kosher salt, and black pepper until smooth and creamy. Taste and adjust salt or lemon if needed — it should be bright and tangy. Set aside. This can be made up to 3 days ahead and refrigerated.
  2. Prep the components: Slice the turkey into 1/4-inch thick pieces and the apple into 1/8-inch thick rounds (no need to peel). Grate the Gruyère on the large holes of a box grater. Have the arugula ready. Lay out the bread slices on a cutting board.
  3. Build the sandwiches: Spread about 1 tablespoon of aioli on one side of each of the 8 bread slices. Divide the turkey evenly among 4 slices (using the aioli side up as the base). Top the turkey with 2–3 apple slices, then a quarter of the grated Gruyère (about 1/3 cup per sandwich), and finally a small handful of arugula.
  4. Close and press: Place the remaining bread slices on top, aioli side down, and press gently with your palm to compact the layers. If your bread is very soft, you can wrap each sandwich tightly in plastic wrap and press for 5 minutes to help it hold together.
  5. Butter the outsides: Spread about 1 teaspoon of softened butter on the top and bottom exterior of each sandwich. This is the key to a golden, crisp crust — don’t skip it. (If you prefer, you can brush with olive oil instead.)
  6. Heat the pan: Place a large heavy skillet (cast iron is ideal) or a griddle over medium heat. Let it preheat for 2–3 minutes until a drop of water flicked on the surface sizzles and evaporates immediately. Add 1/2 tablespoon olive oil and swirl to coat.
  7. Griddle the sandwiches (first batch): Carefully place 2 sandwiches in the pan (or as many as fit without crowding). Cook, pressing down with a spatula or a smaller pan on top, for 3–4 minutes per side, until the bread is deep golden brown and the cheese is melted. Adjust heat to medium-low if the bread browns too fast — you want the cheese to melt before the bread burns.
  8. Repeat with remaining sandwiches: Transfer the first batch to a cutting board and repeat with the remaining 2 sandwiches, adding another 1/2 tablespoon of oil if needed. Keep the finished sandwiches warm on a baking sheet in a 200°F (95°C) oven if you like.
  9. Rest and slice: Let the sandwiches rest for 1 minute off the heat — this allows the cheese to set slightly so the layers don’t slide apart. Cut each in half diagonally with a serrated knife, pressing down gently rather than sawing, to keep the filling intact.
  10. Serve immediately: These are best eaten hot, while the cheese is still stretchy and the bread crisp. If you’d like, serve with extra mustard aioli on the side or a few cornichons (optional, but no pork products).

Notes

Storage: These sandwiches are best fresh, but you can wrap leftovers tightly in foil and refrigerate for up to 2 days. To reheat, unwrap and place in a 350°F (175°C) oven for 8–10 minutes, or until the bread re-crisps and the cheese melts again; avoid microwaving, which makes the bread soggy. Freezing is not recommended for assembled sandwiches, as the apple and arugula will become mushy. The mustard aioli can be made up to 3 days ahead and stored in an airtight container in the fridge. For a gluten-free option, use sturdy gluten-free bread and press gently.
