Steaming with the Thermomix: The Best Forms Compared

Steaming is considered one of the gentlest cooking methods available – and the Thermomix makes it particularly easy for you. But which Thermomix steaming form actually fits best into your everyday routine? Whether you want to prepare vegetables, fish, eggs, or even desserts in the Varoma: the right form makes the difference between a good and a great result. In this article, we introduce you to the most important options and help you make the right choice.


Why choosing the right steaming form is so important

The Varoma attachment on your Thermomix is your steaming tool – but what you put inside determines the cooking result, cleaning effort, and flexibility. Without a suitable form, smaller ingredients quickly end up in the water vapor or stick to the bottom of the Varoma insert. A good Thermomix steaming form sits securely, allows steam to circulate, and is easy to clean afterwards.

Furthermore, a suitable form opens up completely new possibilities: cakes, pudding, eggs in a glass, fish fillets, or meatballs – with the right silicone steaming form, the Varoma becomes a mini-kitchen in steam.


Common steaming forms for TM6 and TM7 at a glance

1. Round silicone forms

The round silicone form is a true all-rounder. It fits optimally into the Varoma container, uses the available space efficiently, and is suitable for a variety of dishes. Whether cake batter, ground meat mixture, or rice pudding – round forms are particularly versatile in practice.

What you should pay attention to:

  • Fit: The form should not completely block the steam, but should leave room on the sides.
  • Material: High-quality, BPA-free silicone is a must – it is food-safe, temperature-resistant, and dishwasher-safe.
  • Stability: Thin-walled cheap forms can lose their shape in hot steam.

Mixcover offers round silicone forms specially tailored to the Varoma that meet exactly these requirements. The forms are made of food-safe silicone, BPA-free, and dimensioned so that steam can circulate unhindered.


2. Rectangular silicone forms

If you want to use the space in the Varoma particularly efficiently, opt for a rectangular steaming form. This variant is particularly suitable for:

  • Fish fillets and chicken strips
  • Small vegetable casseroles
  • Bread and cake recipes that require an elongated shape

The rectangular silicone steaming form Thermomix can also be easily stacked or combined with the Varoma insert tray – so you can cook on two levels at the same time.

Tip: Make sure the form is actually designed for the Varoma. Standard baking forms from the supermarket are often too large or too deep and don't fit in the Varoma lid.


3. Muffin forms and mini-portion forms

For family meals or meal prep, small portion forms are a practical solution. You can steam multiple mini-portions at the same time – ideal for:

  • Vegetable muffins for children
  • Meatballs in uniform size
  • Small soufflés or puddings

Mixcover offers silicone forms in muffin design that were specially developed for steaming TM6 TM7. Multiple forms can be placed side by side in the Varoma, and thanks to flexible silicone, the finished portions can be easily pushed out – no greasing needed.


4. Inserts and silicone set combinations

Sometimes less is more: a single set of coordinated forms can do more than several individual solutions. Mixcover offers sets that combine different forms – for example, one large round form plus several smaller molds. That way, you always have the right size on hand without cluttering your kitchen cabinets.


Silicone vs. other materials: What speaks for silicone?

You may be wondering why silicone is almost exclusively recommended for Thermomix steaming forms. The answer is simple:

Property Silicone Plastic Metal
Temperature resistance Up to 230 °C Often limited High, but heavy
BPA-free Yes (with quality products) Not always Yes
Dishwasher safe Yes Often yes Yes
Flexible (demolding) Yes No No
Steam permeable (sides) Yes (if well designed) Varies Varies
Food-safe Yes Not always Yes

Silicone clearly has the advantage in the steaming area: it is light, flexible, heat-resistant, and easy to clean. However, quality is crucial – inferior silicone can warp or give off unpleasant odors. Mixcover's silicone forms are made from food-safe, BPA-free material and are produced in Germany. This ensures consistent quality and gives you a good feeling when cooking.
