Why you’ll love this recipe

A cold ham and cheese croissant is already a beautiful thing. But bake it with a honey mustard glaze? It’s on a completely different level!

The glaze caramelises slightly, the cheese melts into the prosciutto, and the whole thing comes out gooey and incredible.

And the best part? It only takes about 5 minutes of hands on time. That’s the kind of recipe worth having up your sleeve!

Ingredients

Confused about what ingredients to buy? Not sure about a substitution? Here’s everything you might need to know…

• Croissants – Use the best you can afford. Bakery croissants will always give you better results than supermarket ones. My personal favourite are from the Lidl bakery!
• Gouda – A great melting cheese that holds its shape rather than spreading everywhere. If you can’t find gouda, try gruyère or emmental – both would work just as well. Avoid anything too soft or spreadable.
• Prosciutto – Thin sliced is best here. Parma ham works great too if you can’t find prosciutto.
• Honey mustard – This is the star of the show! Don’t substitute with regular mustard. The sweetness of the honey is what makes the glaze so special. If you can’t find honey mustard, use dijon mustard and add a little honey.
• Olive oil – This is mixed with the honey mustard to make the glaze. Any mild olive oil will do.

Emma’s top tips

Here are tips you’ll find helpful when making this recipe.

• Bake these just before eating, as they tend to get cold quite quickly. Serving on warmed plates can help.
• Don’t be shy with that glaze. Give each croissant a really generous coating – it’s what makes this recipe so special!
• My favourite lazy tip? Line your baking tray with foil to save on washing up!
• Feeling adventurous? Try swapping the gouda and prosciutto for mozzarella and pepperoni, then glaze with garlic oil and a pinch of oregano. Pizza croissant sandwich… you’re welcome!

Timings

Have limited time? Struggle with recipe timings? Or juggling around other things? Here’s some time managing info to make your life easier!

• Prep time is only 5 minutes. This really is a super quick recipe!
• Baking only takes around 6 minutes in a preheated oven.
• Still need to save time? Slice and pre-fill the croissants, and make the glaze in advance. Then glaze and bake just before serving. Perfect for when you have guests!

Product suggestions

Life in the kitchen is SO much easier when you have the right equipment! Here are the tools I used and recommend…

• Silicone pastry brush – Essential for getting the glaze evenly over every bit of the croissant. A silicone one is much easier to clean than a traditional bristle brush.
• Baking tray – You’ll need one large enough to fit your croissants in a single layer. Line it with foil for easy cleanup!

Here is what you will need to make 2.

Please note, this recipe includes both UK metric and US Cup measurements.

• 2 x Large Croissants
• 2-3 x Slices of Gouda Cheese

• 1 tsp Honey Mustard
• 3 tsp Olive Oil

Essential equipment

Preheat your oven to 190°C/Fan 180°C/380ºF.

First, carefully slice your croissants (x 2) in half lengthways, and lay a slice of gouda (x 2) inside each one.

Next, top the cheese with a slice of prosciutto (2 large or 4 small).

If you’re feeling indulgent, you can always add extra cheese and prosciutto!

To make the glaze, simply mix the honey mustard (1 tsp) and olive oil (3 tsp) together in a small bowl or ramekin. Then generously brush it over the top of each croissant. Don’t be shy!

All that’s left to do is pop them onto a baking tray, and bake in the preheated oven for 6 minutes until warmed through and melted.

Serve straight away, and enjoy!

How to store croissant sandwiches

These croissant sandwiches are best eaten fresh from the oven. I don’t recommend storing them to eat later.
