Our thoughts about the new TEFAL Optimo 19L convection oven - customer review Tefal Optimo 19L mini oven Couple of years ago it was very difficult to find a decent mini oven that wouldn't take too much space and would a good job for occasional baking. I remember my grandma bought couple of these but all of them were cheap and were only good for some warming up rather than serious cooking. Thankfully these days things have changed and Tefal recently released few very good convection ovens in different sizes but all very capable in the kitchen. The one that I reviewed the other day was the Optimo 19L which is the smaller version. And for those who need more space there is the Optimo 33L which should be good for roomier dishes.
