In a bowl, mix 2 cups/260g bread flour, 1 tsp salt, and ½ tsp instant yeast.
Add 1 cup/285g of plain Greek yogurt and mix until you have a dough, add more yogurt if needed form into a fairly wet dough (mix for 5-6 minutes).
Line the inner pot with baking parchment and place the dough inside.
Place the lid on, don’t set to seal, (remove rubber seal if tainted to avoid onion flavored bread).
On your Instant Pot, select Yogurt.
Make sure your Instant Pot is set to Normal 4 hours. Press adjust until display shows 4.00. Display will go to 0.00 and count up.
If you have the Duo Evo Plus select Yogurt/Custom/4.00/Temp 110°/f/43°/c/start. Display will count down once up to temp.
After proving for 4 hours, remove the dough from the pot, place on a floured surface. Gently shape into a ball, cover with little extra flour and a dish towel.
In the meantime, place a Dutch oven into your oven, pre heat to 450°/f / 230°/c for 30 minutes.
After 30 minutes place the dough into the Dutch oven. Flour then score the top and place the lid on.
Bake for 25 minutes, then remove lid and bake for another 10 minutes or until browned.
Switch off the oven leaving the door ajar for 30 minutes, then remove from Dutch oven and cool on a wire rack.
Notes
Tip: It's a good idea to place your Dutch oven on a metal baking tray, this prevents the bottom of the bread from burning.
