This indulgent prosciutto and Gouda croissant sandwich becomes extraordinary with a simple honey mustard glaze. It’s surprisingly quick to prepare and delivers an impressive result that’s perfect for breakfast, brunch, lunch or a casual gathering.
Think of it as a glorified ham-and-cheese—only better. Ready in minutes, this sandwich always brings smiles and is an easy, reliable recipe to have on hand when you want something special without fuss.
If you’re a croissant fan, you’ll love how versatile they are. They work for any meal and pair beautifully with savory fillings. I often experiment with ingredients I love, and honey mustard is one of those small additions that elevates everything it touches. Use quality ingredients where you can—good Gouda and tasty prosciutto make all the difference.

I prefer baking these just before serving so the croissants stay crisp and the cheese is melty. They’re also ideal for entertaining: assemble them quickly, brush on the glaze and bake while guests arrive — it really only takes a few minutes.
If you prefer sweet treats, croissants are excellent for puddings and other desserts too, but here we’re keeping it savory and simple.

Croissant sandwich recipe tips
- Choose the best ingredients you can afford—simple recipes rely on quality, so let the flavors shine.
- Bake just before serving. Croissants cool fast and can become soggy if left too long.
- Be generous with the glaze—more than you think will enhance flavor and browning.
- If substituting the Gouda, avoid cheeses that become overly runny when melted; you want a manageable sandwich, not a dripping mess.
- For an easy cleanup, line your baking tray with foil.

This recipe includes both UK metric and US cup measurements.
Ingredients
Serves 2
- 2 large croissants
- 2–3 slices Gouda cheese
- 2 large (or 4 small) slices prosciutto
- 1 tsp honey mustard
- 3 tsp olive oil
Essential equipment
- Baking tray
- Pastry brush
Instructions
Preheat the oven to 190°C (Fan 180°C / 374°F).
Slice each croissant in half lengthwise. Place a slice of Gouda inside each croissant; trim if necessary. Add a slice of prosciutto on top of the cheese. If you want an extra indulgence, add another slice of cheese.

Make the glaze by whisking the honey mustard and olive oil together in a small dish. Generously brush the mixture over the tops of each croissant so they brown and gain flavor.

Place the croissants on a lined baking tray and bake for about 6 minutes, just until warmed through and the cheese melts. Serve immediately for best texture and flavor.

That’s it—quick, impressive and delicious. Enjoy them hot straight from the oven to keep the croissant crisp and the cheese wonderfully gooey.

See that melted cheese, savory prosciutto and glossy glaze? It’s irresistible. You can also experiment with variations: swap Gouda and prosciutto for mozzarella and pepperoni, brush with garlic olive oil and sprinkle oregano for a pizza-style croissant sandwich—add a little tomato passata if you like.
