Dissolve yeast in water in a large bowl. Add salt and honey. Mix until all the ingredients are dissolved.
Add oats first and mix, and then all the flour. Mix into an even dough with a wooden spatula or similar. The dough should be soft and slightly sticky.
Sprinke over with flour and cover the bowl with a cloth. Let the dough raise for 1-2 hours.
Heat oven to 275° C.
Pour the dough on a well floured kitchen surface. Do not knead the dough as you don't want to destroy the bubbles!
Divide the dough into 3. Form 3 baguettes that are as long as your baking tray. You need plenty of flour here. Twist the baguettes, if you wish, as you are placing them onto the baking tray covered with baking parchment.
Sprinkle the baguettes with little flour and bake straight away for about 15 minutes.
Let the baguettes cool without covering them.
