Although some people prefer the functionality of twist dial toaster ovens, it is no denying that digital controls allow you more control and precision in cooking.  The problem, however, is that toaster ovens with digital controls usually come at higher prices.  Therefore, finding one at a reasonable price is sometimes challenging.  The DeLonghi DO400, though, is one toaster oven that is both affordable and comes with easy to use digital controls.

While the price and the benefit of having digital controls are definitely positives, not all people were satisfied with this toaster oven.  In fact, reviews show very mixed feelings from consumers.  At the time of this writing 50% of the people gave this model a rating of 4 or 5 stars with 10% giving it 3 stars, and the remaining 40% giving it 2 or 1 stars.  Therefore, we will examine the DO400’s features and discuss what people like and dislike about this particular unit.


The DeLonghi DO400 has a black exterior with chrome trimming around the front and door handle.  Customers said that it looks modern and with the digital controls it gives it an updated look and makes it look more expensive than it is.

The glass door is tinted, so they also mentioned that this does make it a bit difficult to see the food inside well.

Toasting & Cooking

The overall sentiment from customers was that this model works better as an oven than a toaster.  Consumers liked that the oven heats up quickly and bakes evenly.  Many did mention, however, that the oven temperature has a tendency to be higher than what is displayed.  Therefore, they warned that you must take this temperature difference into account when setting the temperature. On the whole, though, users were satisfied with the baking and broiling ability of the DO400.

Note: In case you need some help with setting the time or temperature, the user manual does come with suggested cooking times and temperatures for a number of foods like pizza, fish, chicken, etc.  

For toasting, this model comes with 14 different levels of browning to choose from.  However, any setting over the lowest was too dark for many peoples liking.  Therefore, users suggested that you start with the lowest setting first.  Additionally, they suggested you keep an eye on the toast as you may want to stop it before the time is finished.  Therefore, if you like your toast dark, then this model is perfect for you.  If not, you will have to keep a watchful eye on your bread so that it doesn’t get too dark.

There weren’t a lot of comments in regard to the Keep Warm function, but the ones we read were favorable.

Using the DeLonghi DO400

Being that the DO400 is digital, it comes with some nice advantages.  One of them is that when you toast something, you can see a countdown timer.  Also, depending on how hot the oven is from prior use, it will automatically adjust the time for the toast.  You can also check the temperature at any time during cooking by simply pressing the Temp/Select/Clock button.

Most users found the digital controls very simple to use and just about anyone should be able to figure them out without any difficulty.  The control panel is clearly labeled, easy to read, and uncluttered.

To choose the function, press the Mode button until the desired cooking mode is highlighted.  If you need to adjust the temperature, just push the Temp/Select/Clock button until you reach the temperature that you want (goes up to 450°).  To select the time or toast shade, just push the + or – buttons.  Finally, press Start/Stop.  That’s it!

It should be noted that this unit comes with a rather loud alert system.  The toaster oven will beep with each push of a button and will also beep 3 times when it has finished a cooking cycle.  Some customers liked this feature as they could hear when the oven has finished from another room.  However, many felt the noise was too loud and found it bothersome.

The DO400 does have a crumb tray to help make cleaning easier.  However, it is only accessible from the bottom or underneath the unit.  Therefore, you must physically lift the toaster oven up as shown in the pictures below.


The DeLonghi DO400 comes with a wire rack, a bake pan, and a broil rack.  All are the typical accessories found with other toaster ovens and are made of average quality.

Customer Wishes & Complaints

One of the biggest complaints with this toaster oven has to do with toasting.  Many thought that the DO400 over toasted the bread – even on the low settings.  Some people were quite happy with the results, but overall, most would have liked to have seen lighter toasted bread.

While some people like the fact that the toaster oven has an alert system, many felt it was simply too loud.  Therefore, if you need to make toast in the early hours when others are still sleeping, this could create a problem.

A feature consumers would have appreciated with this unit is an automatic eject rack.  The rack does not automatically pull out when you open the door and so you must use an oven mitt or something else to get the rack out.  Additionally, some said that with this particular unit the rack is a tight fit and therefore requires a little more force to get out than others.

The crumb tray only being accessible from the bottom was another common gripe found.  Users would have preferred one that was accessible from the front so that they don’t have to lift up the toaster oven every time they want to clean it.

A couple people also would have liked to have had non-stick interior walls for easier cleaning with this unit.

Lastly, the exterior of the oven can get hot.  However, you will find complaints about heat with almost all toaster ovens (more so with less expensive models).

Summary of the DeLonghi DO400

If an alert system doesn’t bother you and you want a compact oven that has easy to use digital controls, then the DeLonghi 400 may be a good fit for you.  Just make sure that you read the instruction manual for proper toast settings and take note that you may need to watch the toast and stop the cycle early for a more desired shade level.

    best toaster oven i’ve ever owned.
    easy to clean and toasts perfectly.
    the only con i have is the finish buzzer is to loud.
    would definitely recommend.

    I have 2 of these, one at home and one at a cabin. I love the size. It takes up very little counter space, but most importantly, I can get an 8×8 baking dish in it, so I use the baking function most often. The digital display on one of my ovens had a portion of the LED display burn out. Now its hard to figure out the temperature. If they made this oven with more reliable manual controls, I’d buy a couple more just to have on hand when these go out.

      I like the toaster oven and had the LED display burn out, as well. You can find the manual @ manualsonline and find the temperature settings. The bake temperature starts at 350 degrees and the next beep is 375, next beep 400, and so on until 450 max. You can also decrease the temperature to 200, so I would think if you start at 350, each beep decreases the temperature by 25 degrees.
