Our Verdict

Delivering impressive results across the board, the Toshiba EM131A5C is one of our favorite microwaves that we have reviewed. This larger microwave quickly and evenly heated up all sorts of different types of food and has plenty of user-friendly and convenient features and functions. It did particularly well at defrosting frozen items completely without cooking them. This appliance is one of our favorites and we highly recommend it to anyone searching for the best of the best.

Our Analysis and Test Results

The Toshiba EM131A5C is one of the larger and more expensive options we have tested, so it isn't the best option if you have a smaller kitchen or are shopping on a budget.

Heating


The Toshiba EM131A5C got off to a decent start in our first round of tests, delivering above-average results. We compared and scored how evenly this microwave heated up a mixed plate of leftovers, canned soup, and some slices of pizza, as well as looking at the speed and evenness of heating by measuring the temperature increase in a beaker of water and making a heat map with marshmallow fluff.


While most of the marshmallow in the heat test heated up consistently, we found there is a solid hot spot in the center of the sheet, causing it to darken significantly more than the rest, to the point of burning.

A very prevalent hot spot appeared in the middle of the heat map.

The Toshiba EM131A5C did much better in the speed test, raising the 125 mL of water a whopping 110.6°F after 45 seconds of microwaving. Unfortunately, the performance of this product decreased again when it came to our leftover test. We used the sensor reheat function on our plate of green beans, sausage, and potatoes and found that it barely heated up the food and there was a significant temperature discrepancy between the different types of foods.

Regrettably  we found the 3 types of food differed quite a bit in temperature after heating.

This appliance also didn't do that well with the pizza, with the crust coming out on the cooler side while the cheese was scalding.

Fortunately, the Toshiba EM131A5C did significantly better with the canned soup, heating it up to the perfect serving temperature upon following the heating instructions.

Frozen Foods


The Toshiba EM131A5C did even better in our second series of tests, heating up premade frozen foods evenly and effectively. We scored performance by using a group of thermometers stuck into different areas of a Hot Pocket, personal sized frozen lasagna, and a frozen burrito and comparing the differences in temperature.


This microwave did exceptionally well with the Hot Pocket, heating it up almost perfectly. There was only an average difference of 7°F between the left, right, and center. It did almost as well with the frozen burrito, with the average temperature difference only increasing to 13°F between the different areas.

The center region was just a bit cooler than the ends.

However, it only did about average with the frozen lasagna, showing marked temperature differences across the entire lasagna.

Defrosting


It was in our defrosting metric where the Toshiba EM131A5C really stood out from the rest of the competition, easily delivering one of the best overall performances we have seen out of any microwave to date. In this metric, we attempted to defrost a one pound block of ground turkey using the appropriate settings.


This microwave perfectly defrosted the entire block without cooking it in just under 10 minutes, notifying you to flip the meat halfway through defrosting.

We like how convenient and easy to use this Toshiba microwave is.

Ease of Use


Our last round of tests looked at the ease of operating the Toshiba EM131A5C, where it scored quite well. We compared the ease of using the interface, how well the preset functions worked, the internal lighting, and if it slides around on the countertop during normal use.


This microwave has a +30 Seconds button that automatically starts once you hit the button, as well as quick start functions for 1-6 minutes. It has a solid internal light and stays in place easily and doesn't move at all when opening, closing, or pushing buttons.

All in all  we highly recommend this Toshiba model.
All in all, we highly recommend this Toshiba model.

It can be used as a standalone timer and we found the popcorn preset to be quite effective, with some kernels just beginning to overcook at the end of it but none burning.

Value


While we think the Toshiba EM131A5C is an excellent product, it is one of the more expensive options out there, precluding it from being a great bargain buy.

Conclusion


If you want a large capacity and high power microwave that does an excellent job with frozen foods, then this should be one of the first options you consider. It performed almost perfectly in our defrosting tests and heated up most foods very evenly.
