This turkey croissant sandwich is the perfect finger food for tea parties or casual get-togethers.
With very basic ingredients, you might not even have to go to the grocery store for this recipe. Well, that’s if you always have croissants at home. Which we all do right? 😉 If you want to go above and beyond with this recipe, you can even make your own croissants from scratch!

Easy Turkey Croissant Sandwiches
My favorite part about these croissant sandwiches is the Dijon mustard mayonnaise because it gives the croissant sandwich a nice little kick of flavor. I prefer to use petite croissants because they look more elegant than a larger croissant cut in half. But that’s totally optional. I just think anything petite or miniature is cute 🙂
This recipe makes 6 sandwiches – enough for the entire family.
Ingredients:
- 6 petite butter croissants
- 18 slices smoked turkey breast
- 3 slices Havarti cheese
- Romaine lettuce
Sauce:
- 1/3 cup real mayonnaise
- 4 tbsp sour cream
- 3 tbsp Dijon mustard
- pinch of black pepper
How to make The Croissant Sandwich
As they say, the secret is in the sauce! And I’m sharing that secret sauce with you.
1.) Make the secret sauce
In a bowl whisk together mayonnaise, sour cream, Dijon, and black pepper, and set aside.
2.) Toast the croissants
Cut each croissant in half and toast in the toaster on low heat. If you want to save time, you can also just put all 6 croissants – sliced – in the oven and broil until toasted.
3.) Put the sauce on the bread
Generously spread the Dijon mayonnaise on one half of the croissant, add 3 slices of turkey breast, half slice of Havarti cheese, and a small piece of romaine lettuce. Then top with the other half of the croissant.
What can you substitute for Havarti cheese?
If you can’t find Havarti cheese in the grocery store you can substitute it with Muenster cheese. They have the same flavor profile and both pair perfectly with my sauce.
Can the sauce be used for other things?
Yes, it definitely can! I always make extra mayonnaise because it can easily be used for other recipes or different types of sandwiches.

This looks really good! One question- I’m making for a large group ahead of time and wondering if I could avoid toasting the croissants? Because it’s a large group, I need to prepare ahead. Thanks!

Hi Laura, yes you can avoid toasting the croissants 🙂 I hope you enjoy these croissant sandwiches 🙂
LaTisha says
Delish! The dijon Mayo is delightful. Was so glad to find the Havarti cheese but if you can’t find, use muenster.
simplyhomecooked says
Thank you LaTisha! The dijon really adds beautifully to the sandwich! Thank you for your feedback 🙂

I made these last time for a party, the best sandwiches i have ever made. I am making them again today for another party. One tip would be to get everything at Costco. That is what i did this time, much cheaper if you are making a large amount. I am making for 30 people today. Last time i made them, everyone raved how good they were.
