The Hamilton Beach 31401 and the Mueller 4 Slice (MT-175) and both standard small toaster ovens, so it only makes sense for them to cost around the same.

The Muellers wins slightly in terms of design and usability by having a detachable crumb tray that makes cleaning easier and an overall higher build quality. What really set them apart and also made us choose the Mueller as our best value small pick was the Mueller’s performance score.

Despite not having a high power output and a convection system like larger units, the Mueller produced very good results in our baked pizza and roasted whole chicken tests. It still had a weakness in baking frozen fries like many other same-sized models though.

Credits where credits due, the Hamilton has a very good toast score as well, even a tiny bit higher than the Mueller. However, it didn’t perform as well as the Mueller in baking pizza and roasting whole chicken despite having a slightly higher power output.

With our Toast test, we determined the best option was right at the position of the Toast icon—around 4 minutes 15 seconds on the timer, scoring a 7.7/10. Turning the knob halfway down would result in no color and turning it halfway up nearly burnt the toast.

With 4m 15s, the Hamilton Beach produced 4 pieces with a light golden brown color on the top and golden on the bottom. Although that was great, the top and the bottom were quite different and they were both only about 80% even throughout. Thus, we gave it a 7.5/10.

The first batch of toast had a nice balance of crispiness on the outside and softness on the inside, deserving an 8/10 for taste. Our head chef Tuyet Pham determined it would go well with pretty much everything including eggs benedict, omelet, and especially sandwiches. It wasn’t as suitable for soup but the second batch was.

The second batch got crispier and more even in color. However, it also became browner so we gave it a 7.3/10 for consecutive usability. If you want the second batch to be the same as the first, remember to only turn the knob to ¾ to Medium—around 3 minutes 40 seconds.

For our Toast test, we started off by trying the Medium Toast setting which was around 3 minutes 5 seconds on the timer. The four pieces of bread on the upper tray level came out only lightly toasted on top except for one golden brown piece. We then cranked it up to the Dark Toast setting—around 4 minutes 50 seconds on the timer—which, unfortunately, burnt the toast a bit.

Finally, we opted for the middle ground which was 4 minutes on the timer—⅓ of the rotation from Medium to Dark. This setting was tricky to get right on the time dial, so we used an external timer. It gave us the best possible toast results from this oven scoring a 7.5/10 in total.

After 4 minutes of toasting, the four pieces of toast had pretty good surface color. However, the colors varied from light golden to golden brown on both the top and the bottom, so we could only give a 7/10.

Luckily, the varied colors partially meant varied textures which were all good and deserving an 8/10. The golden brown areas had a more crispy outside while the light golden areas had a softer inside. Our head chef Tuyet Pham determined that it would go great with omelets, eggs benedict, and sandwiches but not so much with soup.

After taking out the first batch, we immediately put four more pieces inside to test the oven’s consecutive usability which ended up at 7/10. Also under the identical toasting time, the four pieces of bread became brown with an increased evenness from the first batch. While the color was a bit darker than ideal, the extra crispiness made the second batch more suitable for soups.

The Hamilton didn’t perform well in baking a 9-inch thick-crust meat pizza scoring a 5.6/10.

Compared to the recommended 10 minutes on the label, the oven took only a tad bit longer at 10m 30s. However, this meant that it failed the cooking time criterion with 10 minutes being the time limit for our Pizza test.

For the most part, the crust didn’t have a good toasted coloring and was soft so it got a 6/10. The toppings had pretty good caramelization but some darkened areas of the cheese lowered the score to 7.5/10. After tasting the pizza, our chef gave it a 7/10.

For its low power draw, the Mueller did pretty well in our Pizza test with a score of 7.6/10.

The oven took 9 minutes to bake a 9-inch thick-crust meat pizza which was slightly faster than the label’s recommended 10 minutes. However, compared to our tested toaster ovens, it could only be a 6/10.

The crust had a golden color all the way through and the inside was still moist. If only the crust was a bit more crispy, it would’ve gotten higher than an 8/10.

The toppings were also caramelized quite evenly from the meat and veggies to the cheese, worthy of another 8/10. The cheese was nicely melted but the areas closer to the back of the cooking chamber were more caramelized compared to the rest.

With both the crust and the toppings being 8/10, our chef had no reason to give the pizza one final 8/10 for taste.

This was one of the rare occasions where an oven failed the entirety of our Whole Roasted Chicken test. Our speculations concerned the instability of the heating elements and the fact that the chicken grazed the upper safeguard during cooking.

After 1h 30m—our time limit, the oven wasn’t able to roast the chicken to a desirable outcome and failed the first criterion. After roasting, the skin had no noticeable caramelization and barely enough for a 5/10.

The chicken reached an internal temperature of 176°F which was quite good. However, the meat itself was undercooked and still pink in a lot of areas. Thus, it was another failure. Due to the meat being undercooked, our chef couldn’t taste it to give a score.

The Mueller could barely fit a 3 lb chicken for our Whole Roasted Chicken test. Nonetheless, the result was quite decent at 7/10 in total. If you were to purchase this oven and use it to roast a whole chicken, we recommend cutting it open or chopping it into pieces beforehand.

We first placed the chicken backside down on the baking pan. When we slid the pan in, the top of the chicken breast grazed the upper heating element’s guard and was seared.

After the first 40 minutes, we flipped the chicken to find out that parts of the skin on the back got stuck to the baking pan. Then, when we reinsert the pan, the same problem with the breast happened to the back. Luckily, they weren’t burnt.

However, even after 1 hour and 20 minutes, most of the chicken skin still hasn’t reached a desirable color. The chicken, for the most part, looked like it was steamed and not roasted, so we gave the skin a 5.5/10.

Nonetheless, our chef decided to stop the roasting as the color wouldn’t improve anyway and to avoid overcooking the meat. This cooking time was the equivalent of a 6/10 according to our data.

With such a long cooking time, the meat had no pink spots. However, the chicken’s internal temperature was 185°F-192°F, higher than the USDA recommended 165°F-180°F. Thus, we gave it an 8.7/ for doneness.

While not the most appetizing looking, the meat was very juicy. That, combined with the slight caramelization on the skin, was enough for a 7.5/10 for taste from our chef.

The Hamilton Beach wasn’t suitable for baking 12 oz of french fries scoring only a 4/10.

There were no noticeable changes to the fries after 30 minutes of baking in this oven. Due to our time limit of 25 minutes, this constituted a failure in the cooking time section of our Baked French Fries test.

There was no change in the fries’ color so they received a 5/10. The oven basically thawed and heated the fries so they were very soggy scoring another 5/10. Our chef could only give the fries a minimal score of 5/10 for taste.

Our Baked French Fries test brought out the Mueller’s weakness of not being able to maintain a high temperature due to its low power draw. Its even heat distribution couldn’t help much if the temperature wasn’t high enough, so the final score was 3.6/10.

We stopped the baking after 27 minutes as the fries weren’t getting any more colors. This, nonetheless, was over our time limit of 25 minutes, so it was a 0/10.

The fries had no significant color change and barely enough for a 4.5/10. We ended up with 12 oz of frozen fries that were more similar to being dried in an oven than being baked, so we gave them another 4.5/10 for texture.

Fortunately, the fries were cooked through and not soggy, so our chef could give them a 4.5/10 for taste and not a zero.

As simple as it is, the Mueller has all the standard exterior features of a small toaster oven but also something more. The bottom of the oven acts as a detachable crumb tray which not only makes it easy to remove the falling bits and crumbs but also to clean the entire interior.

The oven has a cool-touch door handle and back buffers to prevent it from being too close to the wall. Unfortunately, it has no cord storage or carrying handles.

Our measurements of the oven’s footprint were 14.96" x 11.61" x 8.86" which pretty much coincided with the manufacturer’s 14.84" x 11.85" x 8.86". However, the weight of the oven by itself was already 9 lbs whereas the label said the entire box was 7.63 lbs.

The Mueller has a basic analog control panel with three dials for temperature, function, and time. The time dial has a stay-on setting to help with its short range, similar to many other small toaster ovens. Interestingly, while the max temperature setting was 450°F, we actually recorded the internal temperature of the oven reaching 500°F on the said setting.

Cooking Functions of the Hamilton Beach 31401 Toaster Oven

Cooking Functions
The function knob of the Hamilton Beach 31401 4-Slice Toaster Oven has 3 cooking functions including Broil, Toast, and Bake.
  • Toast
  • Bake
  • Broil

If you know your way around the kitchen, the bake and broil functions will be all you need. The temperature knob has a Min setting which can act as Keep Warm and maintain the oven at around 100°F.

Different from most other toaster ovens, the Mueller’s Bake function only uses the lower heating elements as opposed to lower and upper. The Broil function still uses only the upper heating elements.

The Toast function is where both the lower and upper heating elements work. Nonetheless, the oven still provides all the basic functions for its intended purposes.

The 31401 has 2 quartz heating elements that cook food using infrared light. To avoid direct contact with baking pans and trays, each one has its own safety guard.

Compared to the more common nichrome heating elements, they produce more heat and cool down faster. In addition, they’re easier to clean and more energy-efficient but not as durable. However, if grease splashes onto the heating elements while cooking, it’ll leave permanent stains.

Nonetheless, the oven suffers from a lack of internal lighting and a convection system, similar to most small units like the Mueller MT-175. Moreover, having only two heating elements may not distribute heat evenly as having four.

Similar to many other small toaster ovens, including the Comfee CFO-BB101, the Mueller lacks a convection fan and an interior light. In addition, it only has two heating elements which can usually lead to uneven heat distribution compared to four or more heating elements.

These heating elements are made of quartz which uses infrared light to cook foods faster than the more common nichrome counterparts. Quartz heating elements also cool down faster, are more energy-efficient and easier to clean but not as durable.

However, if grease splashes onto the heating elements while cooking, it’ll leave permanent stains. This is why they usually have guards which this oven also has.

We could fit four slices of toast, a 9-inch pizza but we could barely fit a 3 lb chicken inside the Mueller, unlike the same-sized Breville BOV450XL. We measured the cooking chamber volume to be around 12.81 liters, slightly different than the manufacturer’s provided capacity of 11.67 liters. However, it could just be a difference in measuring standards.

The rack fits perfectly with the guide, which helps prevent accidents when placing your food in the oven. Unfortunately, by burning a batch of toast, we left some extremely stubborn burnt bits on some rods.

The baking pan rests on the supports of the baking rack to catch any drippings and meat juice, preventing any mess and the risk of fire from dirty heating elements. However, it doesn’t have a good coating and sustained permanent stains after our Baked French Fries and Whole Roasted Chicken test.

The baking pan doesn’t fit into the guide rails and has to on top of the rack. This may prevent the full use of the oven’s capacity and lead to some inconveniences during cooking.

On the bright side, the pan has ridges and grooves to give your food attractive roasting marks and catch the dripping better. It has a coating but is not completely non-stick so you may need to watch out for some stubborn stains after a hefty roast.

Without a tray, falling crumbs are quite a hassle to clean up. However, some can still fall to the bottom of the oven as you remove the tray.

The Hamilton uses durable material but its construction isn’t very sturdy. Even though the control knobs turned smoothly, they felt a bit loose.

For a simple small toaster oven, build quality is all about how durable it is and if it works properly. The Mueller accomplishes that with a sturdy stainless steel casing and smooth-turning dials.

Even though the Hamilton Beach only has three simple control knobs, there are a few things to keep in mind. For the timer knob, when setting it to less than 10 minutes, always rotate past 10 minutes and then rotate back to the desired time.

It’s also tricky to precisely adjust time and temperature but we didn’t find this to be an issue. You can use an oven thermometer and an external timer to get familiar before eye-balling it.

It’s always tricky to precisely adjust time and temperature for an analog-control toaster oven and this one is no different. Nonetheless, you can use an external timer and an oven thermometer to get more accurate readings.

If you frequently use the stay-on feature, you can turn off the oven by rotating the function dial to Off instead of the timer.

Ease of Use

With three control knobs, it’s very simple to readjust cooking settings. The cooking cycle finishes when the timer reaches Off. When this happens, the oven will ding once and shut off. As it has no digital display, you can freely leave this oven plugged in without worrying about power consumption.

It’s easy to keep the door partially open to let food cool down but be careful as the oven’s exterior gets hot to the touch quite quickly. However, opening the door doesn’t stop the oven, unlike some others.

What’s convenient about 100% analog toaster ovens is that it’s very simple to adjust time and temperature during cooking. When the timer runs out, a bell will sound and the oven will shut off. Afterward, you can freely leave it plugged in and not worry about power consumption as it has no digital display.

The door can open at any angle < 50° to let food cool down inside the oven. However, keep in mind that opening the door doesn’t stop the oven. The exterior shell isn’t very thick, so it gets hot to the touch quite quickly during cooking.

The Hamilton Beach oven’s exterior and interior were easy to clean following the steps of our toaster oven cleaning guide. Due to the chicken touching the upper safeguard during cooking, there were some caramelized bits stuck to it. Nonetheless, they were easy to remove with just dish soap and a sponge.

We accidentally burnt a batch of toast during our test and it caught fire which led to some discoloration on the oven’s exterior. Luckily, we were able to remove most of it with an all-purpose cleaner.

What surprised us the most, however, were the permanent stains left on the baking pan. Even after we applied a paste of baking soda and water and then scrubbed it with diluted vinegar, the stains didn’t budge at all.

We clean the stainless steel exterior with no problem. However, after the chicken test, there were burnt bits stuck to the upper heating element’s guard and grease on the cooking chamber’s ceiling. There was ample space between the ceiling and the upper heating element, so we proceed to try every cleaning method possible.

Unfortunately, we could only scrub off the bits. Due to the interior not having a non-stick coating, there were some permanent stains on the cooking chamber’s ceiling and the upper heating element’s guard.

Luckily, the heating element itself was intact. Also, we were able to remove the stubborn stains on the baking pan by brushing them with a paste of baking soda and water.
