What You Need To Know

The must-have kitchen appliance in European and Australian households isn’t an Instant Pot, a Vitamix blender, or even a gleaming KitchenAid stand mixer—it’s a Thermomix all-in-one kitchen machine. Thermomix is the pioneering brand of this countertop appliance, but there are now many competitors making all-in-one machines. These gadgets look like food processors and are equipped with heating elements and a plethora of attachments for stirring, steaming, kneading, measuring, weighing, grinding, and more. The promise is bold: one machine to replace every small appliance in your kitchen. Fans of these machines claim you can use one to cook an entire multicourse meal, including recipes such as hands-off risotto with a steamed fish fillet, warm dip with a side of pita bread, and linguine with steamed mussels and a slow-simmered tomato sauce. 

These machines have been embraced in the kitchens of Michelin-starred restaurants such as Noma, El Bulli, and the French Laundry. Heston Blumenthal purchased 15 Thermomix machines for his Michelin-starred Fat Duck, and Wylie Dufresne reportedly used one to make his famous hollandaise sauce because it allowed him to dial in a precise temperature and control the speed and frequency of stirring. Massimo Bottura, chef of Osteria Francescana (consistently named one of the top restaurants in the world), has a partnership with the manufacturer of another all-in-one machine, HotmixPRO, and reportedly uses his for everything from grating Parmesan to making dough to emulsifying sauces. 

In European and Australian home kitchens as well as professional kitchens, these machines are already essentials. Do they have a place in American home kitchens?

While the promise of “one kitchen appliance to rule them all” sounds appealing, it comes at a hefty price: The contenders in our lineup ranged in price from about $395 to nearly $1,985. While dozens of models exist in Europe and Australia, we considered only the machines that were compatible with North American electrical outlets, leaving us with a total of five models, all sharing the same set of functions: cooking, blending, processing, and mixing. We tested two machines from Thermomix, the more basic TM5 and the recently released TM6, which offers additional functions for slow cooking, boiling water, making caramel, and sous vide cooking. 

All the machines in our lineup are about the same size as a stand mixer and share a similar design: a workbowl that sits atop a base containing a concealed heating element and motor. Inside each workbowl is a blade for chopping and mixing. Every machine in our lineu...
