Are you ready to explore one of the best croissant stuffing recipes ever? Let me introduce my cheesy mushroom stuffed croissants – filled with melted brie, herby mushrooms, and a fresh salad mix for that extra nutrients.
It is no secret that I adore croissants in all forms – plain, sweet, savory, you name it. But what’s even better, is making them bistro-style right at home, any time that craving hits.
Or maybe you have leftover croissants from a day or two ago? Perfect! Time to revive them into something flavorful and memorable. A bistro-style delight! You’ll wonder why you never used stale croissants before.
Why These Cheesy Mushroom Croissants Are One of the Best
The number one reason is that you can use any leftovers or slightly stale croissants and turn them into the most delicious breakfast, brunch, or snack. They even make an adorable picnic idea! Can you believe it?
They are also budget-friendly. The day-old croissants are usually on sale, and they soak up all the flavours so beautifully. Well, isn’t that a win-win.
And can we talk about how simple they are? Seriously. You can easily swap ingredients to fit what you have at home. No brie? Use cheddar, blue cheese crumbles, or ricotta. Vegetarian? Skip the pancetta. No cremini mushrooms? Use whatever kind of mushrooms you have. See? Totally flexible and so easy.

What You’ll Need
Croissants – A day or two old croissants are the best for this recipe. They soak all the flavours so beautifully. You can absolutely use fresh croissants, I’ve done that many times.
Brie – This cheese type is great for toasted pastries, so it is the best cheesy filling for croissants. However, if brie is not your thing – use whatever cheese you have. You can opt in for a blue cheese, ricotta, or the good old cheddar.
Mushrooms – I like cremini mushrooms, for their deep flavour, but any kind will do.
Pancetta – Thinly sliced pancetta adds great saltiness to balance all flavours. But, you can use prosciutto, pastrami, or ham too.
Green salad mix – I use baby lettuce or any fresh salad mix for a crisp, green, healthy layer.
Salad Dressing – Optional, but I love a drizzle of my honey mustard vinaigrette or any balsamic-based dressing of your choice.
Rosemary – One of my favourite herbs, that adds the most amazing aroma and flavour to the mushrooms.

Ingredients
4 croissants
1 cup sliced cremini mushrooms
100 grams brie, sliced
100 g pancetta, thinly sliced
1 cup green salad mix
Fresh rosemary
1–2 tbsp olive oil (for cooking)
1 tbsp honey mustard vinaigrette (optional)
Directions
- Clean the mushrooms with a damp towel and slice them thinly.
- In a preheated pan, add olive oil and rosemary.
- Cook the mushrooms for about 5 minutes until caramelized. Set aside.
- Slice the brie into thin pieces.
- Cut each croissant lengthwise and start layering: start with the brie, mushrooms, and pancetta.
- Close the croissants and place them on a parchment-lined baking sheet.
- Bake at 350°F (175°C) for about 7–10 minutes, until the cheese melts and the croissants turn golden and crisp.
- In a meantime, toss the salad mix with a drizzle of honey mustard vinaigrette for some extra flavour.
- Gently open each warm croissant and add the salad mix. Close, serve, and enjoy!
Notes
- For extra cheesy look, you can shred some cheddar cheese over the croissants before toasting them in the oven. The melted crispy cheese will make the croissants look so fancy.
How to Store the Croissants
They are best fresh out of the oven, but you can stuff them ahead of time and reheat before serving. That way, the croissant stays crisp, and the cheese melts perfectly.
If you need to store them for few hours, as any other pastry, put them in a paper bag or wrapped in a kitchen towel.
