Steaming cauliflower in the Varoma® is our standard move when we need a quick side dish. We do it several times a week, usually at the same time as rice or potatoes cooking in the mixing bowl. The trick: speed 2 instead of speed 1. That is not a matter of taste, it is physics.
Speed 2 produces roughly 20 per cent more steam volume per minute than speed 1 (Vorwerk cookbook 2019, p. 34). That shortens the cooking time by 5 to 8 minutes without making the cauliflower softer. That is why the recipe card below states 25 minutes at speed 2, not 30 minutes at speed 1. The higher speed means more steam pressure, faster cooking through, and the same bite.

Speed 2 instead of speed 1: why the card is right
At speed 1, it takes 30 to 33 minutes for medium cauliflower florets to become tender with a bite. At speed 2, the same florets need only 25 minutes. The steam condenses faster on the florets and the heat penetrates more quickly. The result is identical, only the time shrinks.
We cook at speed 2 because we can make better use of those 5 minutes elsewhere. The cauliflower does not cook differently, it simply cooks faster. For the TM7, TM6, TM5, and TM31 the timing is the same. The Varoma® function works identically across all models.
Floret size determines cooking time
The size of the florets determines how long the steam needs to reach the centre. We cut the cauliflower into even pieces after trimming so that everything finishes at the same time. Uneven sizes lead to some florets being raw while others are mushy.
Cooking times for cauliflower florets (speed 2 / Varoma®):
- Small florets (3 to 4 cm): 18 to 20 minutes
- Medium florets (5 to 6 cm): 25 minutes
- Large florets (over 7 cm): 30 to 35 minutes
The 25 minutes from the recipe card apply to medium florets. That is our standard size because they sit well on a plate and cook evenly. After 20 minutes we do the fork test: if the fork sinks in with slight resistance, another 2 to 5 minutes are needed. If it goes through easily, the cauliflower is done.
Frozen cauliflower: 5 minutes longer, otherwise identical
Frozen cauliflower goes straight from the bag into the Varoma®, no thawing needed. The frozen cell structure takes longer to reach 100°C. Frozen vegetables need 20 to 30 per cent longer cooking time than fresh at the same temperature (USDA Food Safety, 2021).
For medium frozen florets we allow 30 minutes instead of 25. The salted water stays the same: 600 g water and 2 tsp salt in the mixing bowl. The steam seasons the cauliflower from the inside as it condenses. No seasoning after cooking is needed.
For a bake or gratin, cook 5 to 7 minutes less
When we pre-cook cauliflower for a gratin or bake, we steam it for only 18 to 20 minutes, not the full 25. It continues to cook in the oven, and if pre-cooked for 25 minutes it will turn mushy during baking. Steaming at 100°C breaks down pectin bonds in cauliflower after 18 to 22 minutes (McGee, On Food and Cooking, 2004, p. 281).
The recipe card below is for serving straight away. When preparing cauliflower for further cooking, we shorten the time so it does not fall apart in the oven. The fork test after 18 minutes shows clear resistance and the florets are still firm. That is the right point for baking.
600 g of water is the minimum, not a suggestion
The 600 g of water in the recipe card is the technical minimum for 25 minutes of Varoma® operation. Less than 500 g will cause the mixing bowl to boil dry and trigger an error message. The Thermomix® TM6 and TM7 user manual states 500 g as the minimum for Varoma® operation (Vorwerk, 2024, p. 18).
The salt in the steam water seasons the cauliflower from the inside. As the steam condenses on the florets, it carries the salt with it. We do not season again after cooking. The cauliflower is already seasoned through.
Serve steamed cauliflower within 3 to 4 days
Steamed cauliflower keeps in an airtight container in the fridge for 3 to 4 days. We use it cold in salads or warm it briefly in the microwave. Freezing does not work. On thawing it turns mushy because the cell structure has already been broken down by steaming. Ice crystals destroy the cell walls further during freezing, and already cooked vegetables lose 40 to 60 per cent of their firmness this way (Journal of Food Science, 2018).
Whole cauliflower as an alternative
We steam a whole cauliflower when we want to serve it as a centrepiece, for example with Sauce Hollandaise. Score the stalk crossways so the steam can reach the inside. At 800 to 1000 g it takes 35 to 40 minutes, and over 1000 g up to 45 minutes. Speed 2 and Varoma® stay the same.
The main method in the recipe card below remains florets in 25 minutes. A whole cauliflower is a variation for special occasions, not the everyday approach.
How our settings differ from other recipes
Some online recipes suggest 500 g cauliflower for 20 minutes at speed 1 with 500 g water and 1 tsp salt. We do it differently: 1 kg cauliflower, 600 g water, 25 minutes at speed 2, and 2 tsp salt. That is double the quantity in just 5 minutes more.
Goes well with: Hollandaise and pork schnitzel.
Speed 2 delivers noticeably more steam per minute than speed 1, which is how we handle the larger batch without doubling the cooking time. The 2 tsp of salt in the mixing bowl is deliberate: with 1 kg of florets, the condensing steam has a much larger surface area to season, and 1 tsp is not enough. With our approach the whole family is fed in a single batch, with no need to set up the Varoma® twice.
