Boxing Day Turkey & Vegetable Croissant for Singapore

Turn Christmas Leftovers into a Croissant Treat

Croissant magic is exactly what your leftover Christmas turkey needs.

Christmas is over, the table has been cleared, and now your fridge is full of containers, especially that big one of roast turkey. You’re grateful for the feast, but you’re also thinking, “What am I supposed to do with all this leftover turkey?”

If you’re tired of the usual cold turkey-and-cranberry sandwich, this simple turkey and vegetable croissant recipe gives you something fresher, lighter and more exciting. It turns yesterday’s roast into a new meal that feels bakery-level, yet is easy enough to assemble in a calm, slightly sleepy Boxing Day mood.

With Délifrance Butter Croissants from Délifrance Singapore Wholesale, you get that buttery, flaky French-style pastry straight from your own oven. We’ll show you exactly how to bake them, fill them, and serve them so your leftovers feel like a treat, not a chore.

That container of turkey at the back of the fridge is about to become the star of brunch.

Why This Croissant Recipe Works for Leftover Turkey

This croissant recipe is all about simplicity and freshness. Instead of cooking a new complicated dish, you:

  • Bake the croissants
  • Slice some crisp vegetables
  • Layer everything with your leftover turkey and a drizzle of good olive oil

You reduce food waste, save money, and still serve something that looks and tastes like a special occasion. Among all the leftover turkey recipes you could try, this one fits neatly into a busy Singapore home: minimal cooking, quick assembly, and easy to scale up if relatives drop by.

Using a high-quality butter croissant makes a big difference. The rich, layered dough and crisp shell hold the filling well, so every bite has a contrast of buttery pastry, juicy turkey and crunchy vegetables. The croissant does the “wow” work for you while the leftovers quietly blend in.

Make sure you have some croissants on hand ahead of time to make the recipe.  Place your order here.

Step-by-Step Croissant Instructions

1. Bake the croissants

  • Preheat your oven to 170°C (top and bottom heat).
  • Line a tray with baking paper and place the frozen Délifrance Butter Croissants on it, well-spaced.
  • Bake for about 18–20 minutes, until they are puffed, deep golden and crisp.
  • Transfer to a cooling rack and let them cool slightly so they’re warm but comfortable to handle.

2. Prepare the turkey

  • While the croissants bake, slice your leftover turkey into neat, bite-sized pieces.
  • Remove any tough or very dry bits so the filling stays pleasant and tender.

3. Slice the vegetables

  • Wash and dry the rocket leaves thoroughly.
  • Slice the tomatoes thinly so they layer neatly inside the croissant.

4. Get your flavour extras ready

  • Pour the olive oil into a small bowl so it’s easy to brush or drizzle.
  • If using balsamic glaze, keep it nearby.
  • If you’d like extra creaminess, stir the mayonnaise or salad cream with the Dijon mustard in a separate bowl.

5.Slice and brush the croissants

  • Using a serrated knife, carefully slice each warm croissant horizontally.
  • Keep a small “hinge” if you like, so the croissant opens like a book.
  • Lightly brush the cut sides with olive oil, then add a small drizzle of balsamic glaze if you’re using it.

6. Assemble the filling

  • Layer rocket leaves on the bottom half of each croissant.
  • Add slices of turkey and tomato on top.
  • Season lightly with salt and black pepper.
  • If you’re using the mayo–mustard mix, spread a little on the top half of the croissant or dot it over the turkey before closing.
  • Add chilli or spring onion as a garnish if you like a local twist.

7. Serve immediately

  • Close the croissant gently and serve while the pastry is still slightly warm and the filling is fresh and cool.
  • Because the turkey has already been cooked once, it’s best enjoyed like this, without further reheating.

When you bring the plate to the table and everyone sees golden croissants instead of “just leftovers”, the mood in the room shifts immediately.

Croissant Tips, Variations & Ideas

Keep the vegetables crisp and light

  • Rocket and tomato are a classic match for roast turkey. You can also add a few leaves of baby spinach or mixed salad leaves if you have them, keeping the overall feel fresh rather than heavy.

Add extra flavour if you like

  • For a richer bite, use the mayo–mustard or salad cream–mustard mix as a thin spread inside the croissant. A touch of balsamic glaze also gives a gentle sweetness that works well with roast turkey.

Make it child-friendly

  • Use more turkey and fewer peppery rocket leaves, and skip the chilli. You can even add a mild cheese slice if that helps younger eaters enjoy their turkey croissant more.

Change the texture slightly

  • If you enjoy a bit more crunch, add a few thin slices of cucumber or a sprinkle of finely sliced red onion as a variation. Keep them light so they don’t overpower the rocket and turkey.

Why Délifrance Butter Croissants help

  • The rich, layered dough gives you a croissant that stays crisp outside yet soft inside, so it can handle generous fillings without falling apart.

When your guests bite in and taste that buttery crunch with the peppery rocket and juicy turkey, no one will guess this started as yesterday’s roast.

This turkey and vegetable croissant works beautifully for:

FAQ: Leftover Turkey Croissant Questions Answered

In general, cooked turkey can be stored in the fridge for about 3–4 days in an airtight container. 

For recipes like this croissant, use turkey that has been chilled promptly after roasting and kept cold. If it looks or smells off, it’s safer to discard it rather than risk foodborne illness.

Yes, you can freeze leftover turkey if you’re not ready to use it within a few days. Thaw it overnight in the fridge before making your croissant. Once thawed, keep it chilled and serve it cold in the croissant rather than reheating it multiple times.

Stick to crisp, fresh vegetables that pair well with roast turkey: rocket, tomato and a few mixed salad leaves all work nicely. These keep the croissant feeling light and refreshing, which is especially welcome after rich Christmas meals.

The Butter Croissant is an excellent everyday choice thanks to its buttery recipe and convenient format, but you can also use other Délifrance croissant options such as Le Passionné or Mini Butter Croissants, depending on what you stock. Choose a plain, butter-based croissant for the best flavour with turkey and vegetables. For consistent results at home or in your business, we recommend keeping the Butter Croissant as your go-to.

For food safety, it’s best to assemble only as many croissants as you plan to eat at one time. If you have leftover assembled croissants, keep them covered in the fridge and enjoy them cold within 24 hours. 

Because the turkey has already been cooked once and then served again, we don’t recommend reheating the filled croissant multiple times.
