Blend ingredients from olive oil to salt till well combined. Pour over the potatoes.
Sprinkle the semolina.
Bake for 45 minutes. Pull out the tray and toss the potatoes. Ensure there is sufficient liquid in the pan, if not, add around 1/4 cup hot water.
Put back into the oven and bake for another 45 minutes.
Serve hot with a sprinkling of parsley.
Notes
Vary the baking time depending on how big or small you have chopped your potatoes. I added a stock cube to the water while blitzing. You can use thin home made or store bought chicken stock instead.
