Toasts are an extraordinary morning addition to breakfast plates. They can go with coffee or tea and are considered a go-to breakfast for many. As we’ve come to know, a toast is a crisp and brown bread on both sides.

However, sometimes we find out that only one side of the slice put in comes out well toasted. Thus, we seek to understand why a toaster toasts only one side.

Most toasters toast one side more than the other because the heat from the bottom heater is much closer to the bread than the top heater. It could also be due to the loss of moisture in one side of the bread, which makes that side vulnerable to heat than the other side, resulting in that side being more toasted than the other.

Why Does Toaster Toast On One Side?

This can be illustrated with a person walking under the sun with an umbrella. The heat reaches the umbrella first; that’s the same way it is with toasts. When a slice of bread is closer to a toaster’s heating element, it gets browned and crispy first compared to the other side.

Moisture and bread-type might moreover be one of the reasons why a toaster toasts on one side. Moisture found in bread takes a lot of energy to heat up, and white bread comprises more water content than brown bread.

A thick bread takes longer to heat, and due to its viscosity, much heat is needed to pass to the other side. The side closer to the heat panel loses moisture rapidly and becomes brown and crunchy, while the other is light and less brown.

The temperature of the toaster could be another problem. The heating elements found in a toaster are made of nichrome wires that produce heat through electricity. Inside the toast, slots are found in these wires that induce heat to brown bread.

The spacing of these wires is believed to be the cause of the problem as it deters heat from being disseminated evenly to all parts of the slot.

The size of a toast space is another contributing factor to this difficulty. Smaller slots found in some toasters cannot house larger bread, and larger slots cannot hold smaller bread.

The reason is that smaller bread sits too loosely in the toaster and can’t snuggle closely to the heating wires, which results in a poorly toasted toast.

Another possible reason why this happens could be because crumbs are an impediment. When a toaster is constantly utilized, it can lead to crumbs obstructing the lever.

When this occurs, the toasting lever becomes burnt and won’t allow the flow of electricity. When there is no flow of electricity, the heat won’t pass into the wires.

How Does A Toaster Work?

The nichrome wire in a toaster conducts power to the metal heating components, and plates named mica sheets. As electricity streams and electrons collide, the nichrome wire’s power increases, and the surplus energy is emitted from the coils, heating the bread.

A toaster employs a procedure known as radiation to work. It comprises parts such as the heating elements, bread rack, heat detector, timing mechanism, etc. These parts work closely together to guarantee heat supply to the bread rack to ensure the toasting process is carried out effectively.

Infrared radiation utilized is only detected when the toaster is powered on. The red glowing light noticed is the product of the powered heat.

With a toaster, as the warmth creeps into the bread through light, the particles within the bread begin to move quickly, which gives rise to resistance. It at that point generates a more warm interior to the toast, quickening the cooking preparation by utilizing conduction.

Heating components displayed within the toaster employ a little sum of vitality. Nichrome wire found within the warming component has Chromium and Nickel. It can withstand high temperatures and rust. When power streams through the nichrome wiring and encompassing plates, it slows the collision of electrons with each other, altering the heat.

 Toasters have a control dial that commonly displays five or six settings. The settings found on the control dial will determine the toasting phase wished to be achieved.

A lower level will simply toast bread to the least percentage. The higher the setting level, the more toasted the bread will come to be. Once the bread reaches the set level of toastiness, it pops up, indicating the slices are ready.

A metallic strip is placed in the toaster to read an appropriate temperature close to the heating element. The rate at which each metal heats contrasts, causing them to curl.

If you rely on the browning level chosen, the twisted metal will activate a level. It’ll break the circuit and current of the electricity, halting the flow of energy to the wire, and initiating the spring-loaded pop-up mechanism, which creates a finished slice of toast.

Which Toaster Is Considered The Best For Toasts?

The Cuisinart classic toast is generally considered the top toaster due to its alternatives, effectiveness, easy cleaning, and affordability.

The Cuisinart toaster has two editions which are the two-slice opening and the four-slice space. The two-slice slots are basic but modern and have six levels of browning. The four-slot toaster works better for large families or those who prefer their bread toasted at a go.

It produces good results in less time and creates a golden and crunchy toast even on both sides. They’re inexpensive, durable, and easy to use.

The toast alternatives found include the warm, defrost, and bagel controls. It works well on usual toasts, bagels, and pastries too. The toast setting warms both sides of the bread equally, while the bagel setting only toasts one side of the bagel using low heat.

The setting used for the bagel also applies to thicker bread as it lowers the control of the heating components and includes additional time to the toasting cycle. The defrost button heightens the temperature and toasting time to ensure a warm slice.

Crumbs can build up in a toaster if it’s frequently used, and therefore, to ensure it doesn’t deter the components of a toaster from working viably, it should be cleaned as many times as possible before and after use.

The crumb tray found in the Cuisinart toaster makes the cleaning process easier. The Cuisinart toaster has extra-wide spaces that can suit all sorts of breakfast bread, in this way ensuring the even browning of both sides of a toast.


A toaster makes good toasts that are evenly browned, crunchy, and warm on both sides. Some factors hinder a toaster from working successfully, it toasts on one side more than the other, and other times may get burned.

Understanding how a toaster works can make it easier to avoid such problems and also helps us know if the fault may be from us or the toaster. As such, it is important to go for a toaster considered best as it ensures a toast is flawless, that is, evenly toasted, crisp, and golden all around.
