WMF Stelio: the Cromargan egg cooker with continue-cook function

Prices in euros from Amazon.de, as of 11 June 2026. Prices and availability may differ on Amazon.co.uk.

By Seydhan Cakmak · Editor-in-chief · Updated: · AI-translated from the German original

The WMF Stelio cooks 1 to 7 eggs in a matt Cromargan housing and sets the doneness via a dial and a timer, so there is no need to measure water. Its continue-cook function allows soft and hard eggs in one go: take out the soft ones and keep cooking the rest. The lid and egg holder may go in the dishwasher. A long-lasting branded classic with well-thought-out details.

WMF Stelio: what works, what doesn't?

What works well

  • Continue-cook function: Allows different levels of doneness in one cooking process: take out the soft eggs, keep cooking the rest
  • Timer instead of measuring water: Cooking time is controlled by the timer, annoying measuring of the water amount is no longer needed
  • Doneness by dial: Soft, medium or hard selectable precisely, a beep signals that the doneness is reached
  • Cromargan quality: Matt WMF stainless steel housing stands for longevity and quality build
  • Dishwasher-safe & tidy: Lid and egg holder may go in the dishwasher, the cable winder on the base keeps things tidy

Points of criticism

  • Higher price: At around €32 clearly more expensive than no-name egg cookers, you pay for brand, Cromargan and the continue-cook function
  • Short cable: 0.94 m of cable restricts placement near the socket
  • Base remains hand-wash: Only lid and egg holder are dishwasher-safe, the appliance itself must be wiped by hand

Build quality & everyday use

What carries the WMF Stelio in everyday use: continue-cook function (allows different levels of doneness in one cooking process: take out the soft eggs, keep cooking the rest) and timer instead of measuring water (cooking time is controlled by the timer, annoying measuring of the water amount is no longer needed). We have to be honest about the weaknesses: higher price (at around €32 clearly more expensive than no-name egg cookers, you pay for brand, Cromargan and the continue-cook function).

If you set the device up to save space, make sure it stands on a stable, level surface with some air around it. This protects the mechanics and electronics in continuous use.

“WMF Stelio egg cooker: continue-cook function and timer instead of measuring water, and the trade-off is higher price. At 8.7/10 a safe choice from €32.”

Frequently asked questions about the WMF Stelio

What does the continue-cook function do on the WMF Stelio?
It allows different levels of doneness in one cooking process: as soon as the soft eggs are done, you take them out and simply let the rest keep cooking. That way everyone gets their egg as they like it, without cooking twice.
Do I have to measure the water amount with the Stelio?
No. Unlike many simple egg cookers, a timer controls the cooking time, so measuring the water amount by doneness is not needed. You choose the doneness on the dial.
Is the WMF Stelio dishwasher-safe?
Partly. The lid and egg holder may go in the dishwasher; the stainless steel housing with heating plate is cleaned with warm water and a damp cloth. Regular descaling of the heating dish extends its life.
Is the premium over cheap egg cookers worth it?
If you only cook eggs occasionally, a basic appliance will do. In the Stelio’s favour are the continue-cook function, the timer, the Cromargan build and brand support, points that cheap no-name appliances usually do not offer.
