Buckwheat crepes with mushroom filling are crunchy, gluten-free, savoury thin crepes filled with the best seasonal mushrooms, smooth thyme-aromatized bechamel and baby spinach.
You can find all kinds of filling with these gluten-free savoury crepes. A popular one would be ham and cheese with an egg on top. For this one, I’ve used lovely seasonal mushrooms. To go with the mushrooms what better sidekick than thyme to aromatize the smooth bechamel it swims in? Plus, to give it a little crunch, a few baby spinach. Buckwheat Crepes with Mushroom Filling will become one of your favourite low-carb recipes!
Galette or Crepe?
Buckwheat Crepes are also known as Galettes Bretonnes in France. They are made of water and buckwheat flour which is gluten-free. Sometimes, an egg is added to make it crunchier. Really simple! Some other versions also mix in a bit of normal flour with milk, like a normal white crepe. A true Galette Bretonne should be crispy and crack when folded, filled with little holes and thin like paper.
In Brittany, they use a Billig to cook them on high heat and a long flat spatula to fold them up. On the bright side, there is no need to turn this crepe midway and risk a catastrophe. Since they are so thin, it wouldn’t work. Its colour is also a bit darker than the usual crepes. One important thing to keep in mind is that it doesn’t keep as well as white flour. Buckwheat tends to sour up in the pantry so keep it fresh!
First of all, buckwheat is technically a no-wheat product. Let me explain; it’s actually the seeds of a flower that makes this flour, nothing to do with the usual wheat grass. It’s also a gluten-free flour, so for those of you who are sensitive to gluten, it’s a great alternative. This flour has many health benefits. I can’t cover the whole list here, but you can check it out here.
Mushroom season is on!
Living in Spain, I use those fantastic “Rovellons” mushrooms. I suggest you use your favourite ones, or even better, go grab some nice ones on your walk in the woods next weekend. Otherwise, you can always settle for the humble button mushrooms. I’m never satisfied with the texture of my mushrooms cooked in a pan—too saggy and soft. Since it’s quite a “busy” recipe already, I simply cook my mushrooms in the oven or even better, the air fryer. I leave them in the oven for about 20 minutes or 15 minutes in the air fryer and they end up perfect, evenly cooked and so much firmer.
So, let’s make savoury crêpes for dinner!

Making the crepes
- Bring your nonstick pan to medium-high heat and add a little fat of your choice (oil or butter).
- Mix your base again, add a little base to the pan in order to test your crepes, not too much (.1 mm thick)
- When adding the mix, make sure it barely covers the surface and it’s not too thick (you’ll see the holes forming right away if good consistency, always can add water if too thick).
- Add the baby spinach and the mushroom mix to the crepe while it cooks (no need to turn the crepe).
- Cook the crepe until light brown, fold it up, transfer to a plate.
