The Panasonic NN-CD58JS is a convection oven. It is also a grill. It is also a microwave. And, it does all these things very well. Add them together in combo cooking and the whole is greater than the sum of its parts.
GadgetGuy is about lifestyle tech, and one wonders why we like to review microwaves, coffee makers, home and other kitchen appliances. The answer is that if it plugs in, makes life easier then we will review it – all the better if there is an app for that.
We are quite expert at microwaves having reviewed LG, Panasonic, Sharp, KitchenAid, Samsung, Breville, Whirlpool, AEG, Miele and more. Our review paradigms have changed over the years. Long ago it was all about which microwave oven could nuke food fastest, e.g. Watts power. Then we saw the addition of steam that left vegetables and meats juicier. Some had auto weight functions and some auto cook.
But the true evolution is in the combination ovens.
Why? As housing gets more expensive, space becomes a premium. Kitchens are smaller – much to Uber Eats and Deliveroo’s delight. Evidence of that is more single draw and half-size dishwashers, two-plate cook tops and often no oven at all – replaced by a fancy built-in combo-one-size-fits-all oven.
Of the four combos last year the Sharp R890E impressed us most scoring 4.3-out-of-5 for overall features, value and functionality. In the second spot was the KitchenAid Bake Assist that while a competent microwave focuses on baking – mmm yummy cupcakes.
In the last place was an under-powered, undersized, overpriced ($2K+), European ‘fashion’ brand that would not be out of place in a swanky kitchen showroom. It was so bad to average at everything we decided not to review it. Yes, we should tell you the brand, but they have powerful lawyers.
First, a word on combo-cooking
For the right people, it can and does replace a traditional /microwave/oven/grill. With a little planning, you can avoid using the big power sucking oven or grill element.
But there are a few observations, and we will compare it with our current favourite Sharp.
- Combo cooking is a serial form of cooking. Cook item one, cook item two etc. It is harder to get everything cooked to serve hot at the same time (but you can plate and reheat so no big issue). Both brands are on par here.
- At 27L it is at the top-end of equivalent mid-size units. The Sharp at 25L fits a little less.
- It has a 34cm turntable compared to the Sharp with a 31.5cm. These suit a single or couple – it is not a family sized oven. Don’t try it on a big roast although the extra 2.5cm (one inch) allows for a little more flexibility.
- Combination microwave/fan-forced oven/grill needs entirely different cooking pans. Both ovens come with a baking pan and a rack to adjust the height of the food. But you will need to buy more ‘round’ cooking plates and pans to make the most of turntable cooking.
- The primary advantage of a fan-forced oven is the minimal pre-heat time compared to a full oven of often 20-30 minutes. Panasonic pre-heats a smidgen faster than the Sharp.
- In all other respects use the same cooking time as you would in a larger fan-forced oven or grill.
- The grill will produce crispy golden cheese on toast a little faster than the Sharp. The upside to both is no preheat time.
- And it is possible to use a combination of technologies to get the result. For fear of oversimplifying a frozen pizza can be microwave defrosted, oven baked and grilled for a crispy cheese top in the one device.

99.9% of Australians know how to nuke food. What they don’t know is how long to nuke it to achieve the best results.
For example, my wife cooks morning porridge on full power for three minutes often resulting in the contents overflowing the bowl. A little exploration of the manual’s cooking charts shows setting it at 600W for three minutes is best – Voila.
Note: It also has porridge with milk (or water) auto-settings that selects the right power and time for perfect porridge.
We tested a variety of fresh and frozen vegetables and times were in line with any other similar quality 1000W microwave.
A little exploration of the auto-cook function reveals 29 pre-programmed settings for typical bread, meats, vegetables (fresh and frozen), takeaway, pasta, pancakes (pikelets), pizza (fresh and frozen) and more.
We tested a 1kg lamb leg mini roast that in a Webber BBQ takes about 1.5 hours. The Auto-settings produced a perfectly cooked roast in 40 minutes using a combination of 300W microwave to par-cook and a 180° oven to roast. We did use the grill to caramelise the roast and vegetables after.
