Ingredients & substitutions
You'll be blown away by the amazing flavour of these pesto turkey croissants and it all comes from just 6 ingredients!

Jump to the recipe card for full quantities and instructions.
- Croissants: You can use homemade or store-bought croissants. They freeze well so you can buy them in advance and freeze until you need them.
- Turkey: This recipe is the perfect way to use up your leftover Christmas or Thanksgiving turkey but it works equally well with rotisserie chicken too. You could also try deli turkey.
- Ham: The ham is optional but it works great with the turkey. We always have both leftover but if you don't, just leave it out.
- Basil pesto: You can use store-bought or homemade pesto. The upside to store-bought here, as much as I love to make pesto from scratch, is that it's shelf stable - you can buy it well in advance and have it ready for your post-Christmas meals.
- Sun-dried tomatoes: The sun dried tomatoes in oil, in jars are also shelf stable so you can get them well in advance too. You could swap these for sliced fresh tomatoes too.
- Cheese: You want slices of a good melting cheese here. I use Swiss cheese but gouda, edam and colby all work great too.

Cheese, ham, tomatoes
Those three ingredients themselves make a wonderful toastie (aka melt). Once you've sliced your croissants, sandwich-style, layer up the cheese, ham sun-dried tomatoes.
Should you butter the croissants?
With the buttery flavour of the croissants and the pesto you don't need to spread any butter or even mayo on the croissants but, if you love it, go for it.

Add turkey
Add slices of turkey on top.

Add pesto and bake
Spread pesto over the inside of the tops of the croissants then bake until hot through and the cheese is all melty!
Variations
You can create your own version of these pesto turkey croissants using what you have left from your holiday meal.
- Beef or pork: Go ahead and swap the turkey and ham for sliced roast beef or pork.
- Cranberry sauce: Swap the pesto for cranberry sauce.
- Stuffing: Even stuffing is great stuffed into a sandwich so try that with these turkey croissants.
- Monte cristo croissant: Swap the pesto and sun dried tomatoes for strawberry jam then dust the tops with powdered sugar before serving.
Storage
These are best served fresh so don't bake them until you plan to eat them. Food standards recommends that you don't eat a meat that's been cooked over and over so while cooking it the second time is fine, it's not recommended to then save any of those baked turkey croissants and re-bake them again later.
All that said, I did exactly that after baking these. I stored them in an airtight container in the fridge and baked them a second time the next day and ate them quite happily. It's your choice.
You can assemble your pesto turkey sandwich croissants ahead of time then just bake them when you need them so it makes them a wonderful brunch for a gathering.
