Baking Bread/Pizza in a portable oven????

I've gone thru several.  Try looking up "mini ovens."             :)

These things are much more commonly used in some parts of the world than others. For example they're probably common as nails in Hong Kong, but  are much less common in North America (and even the U.K.). They're sufficiently uncommon that the big online retailers (like amazon.com) mostly don't carry them. [edit] Amazon.com search makes them so very hard to find they appear to not exist at all  ...but they are there. To find them on Amazon, search for
 countertop convection oven electric -toaster -microwave
(you may need to look at several pages of results, as Amazon doesn't seem to prioritize them all onto the first page properly).
You will probably have to visit individual manufacturers websites to find them. (In fact, this seems to me one of the few items that ideally should be purchased from a bricks-and-mortar store rather than online.)

I think most of them will be "convection" ovens. (I'm not quite sure why. Maybe because all recently designed ovens are that way? Maybe because it uses less electricity, and that's very important for a countertop oven? Maybe because blowing air around is a good way to avoid the "hot spots" that are so likely to be prevalent in a small oven? Maybe because it requires less insulation?)

To avoid blowing an electrical breaker by drawing much more electricity than countertop outlets expect, most of them have about the same "wattage" as a toaster oven. They're also for some reason mostly about the same size as a toaster oven. So they all look very similar. But in fact some of them are actually built very differently from a toaster oven, including having plenty of insulation. Knowing which ones without seeing them can be kinda tricky. Most likely though good differentiators  are:

• internal size: look for at least 1.5 cubic feet
• able to hold a sustained high temperature of at least 250C (482F)
• blow up the picture and check that the temperature control has many marks (every 25F? every 10F?)
• the picture suggests the walls are fairly thick, which hopefully indicates insulation

If it can't meet even the requirements above, I think you're right that it's just a "glorified toaster oven" that should be steered clear of. (In fact, unless you want to make toast, I'd also suggest ignoring everything that has the word "slice" somehwere in its description:-)

(Unless you want to rewire, make sure it has the right voltage and plug for your countertop. Most will  ...but with some of the "professional" models I'm a little dubious.)

Oops double post

I have two Breville smart ovens.  They are the larger size, although Breville has now come out with one that is even larger and has three racks. Mine have optional convection.   I haven’t read the Amazon ratings but I have had mine for two years and they operate well.  My oven thermometer shows them at the correct set temperature.    I bake pies in them all the time.  I have baked yeasted loaf bread in them without convection but it does tend to get overly brown at the dome.  A good loaf though.  As I move into sourdough baking in a cloche I’m using my monster gas oven.    I’d like to to know about a good portable bread baking oven that would treat sourdough right and doesn’t cost the earth as my gas bill has skyrocketed since I started this frequent bread baking thing.  Old thread I know but though maybe someone had tried the new bigger one.
