Mueller 4 Slice vs Hamilton Beach 31127D 6 Slice Toaster Oven Side-by-Side Comparison

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.

We initially set the toast knob to Medium—right at the Toast icon—for our Toast test. The bread came away very dark on the bottom but barely toasted on top. Then, the halfway point to Medium gave the toast no color.

Eventually, we settled on a point 3/4 the way to Medium—around 3 minutes 30 seconds on the timer—as the best option, and awarded it a score of 7.3/10.

At our optimal toasting setting, the Hamilton Beach produced 4 pieces with a great, slightly golden-brown color. Though the oven doesn’t have a convection fan, the color distribution was about 80% even so we gave the toast an 8/10.

The first batch of toast was crispy on the outside while still soft and moist on the inside, so we gave it an 8/10 for taste. Our head chef, Tuyet Pham, said it would go very well with everything including sandwiches, soup, omelets, and eggs benedict.

The second batch represented a significant decrease in performance, scoring only 5.5/10 for consecutive usability. The toast had an uneven, dark brown color plus a burnt flavor. If you want the second batch to be the same as the first, remember to only turn the knob halfway to Medium—around 1 minute 55 seconds on the timer.

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 oven left a bit to be desired when we tried baking a 9-inch thick-crust meat pizza. We gave it a score of 6.6/10.

It took 9 minutes and 10 seconds to bake a pizza which was slightly faster than the recommended 10 minutes on the label. It only garnered a score of 5.8/10 after being compared to other toaster ovens in our Pizza test, though.

The crust had a good golden brown color but was soft, so we could only give it a 7/10. The toppings were caramelized unevenly and some areas of cheese got darkened. On the bright side, the toppings weren’t dry, so they got a 7/10. After tasting, our chef gave it a 6.5/10.

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.

Even though the Hamilton Beach could comfortably fit a 3 lb chicken for our Whole Roasted Chicken test, its performance was far from perfect, scoring only 6.3/10.

The oven took 1 hour—our standard for this test—to cook the chicken to a desirable color, so we gave it an 8/10.

After roasting, the skin took on an even golden color on top but only a very light caramelization on the bottom — although that was also even. Unfortunately, the skin was very soft, so we could only give it a 5.5/10.

The chicken reached an internal temperature of 165-176°F which was very close to the USDA recommendation. However, there were pink spots near the bone so we could only give it a 6/10.

The meat was acceptable in terms of texture and juiciness, but didn’t stand out as remarkable. Our chef gave the chicken a 6/10 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.

Baking 12 oz of french fries clearly wasn’t the Hamilton Beach oven’s forte, and it came away with a score of 5.1/10.

This oven took 27 minutes and 15 seconds to put some color into the french fries. That exceeded our time limit of 25 minutes, though, so it failed the cooking time criterion of our Baked French Fries test.

Even though the fries had some golden ends, most of them basically had no color. We gave them a 6.5/10.

Despite being spread out on the baking pan, the fries didn’t crisp up, so they got a 6/10. Our chef gave the fries a 6.5/10 for taste.
