NEFF N90 Built-In Compact Oven with Steam Function Plus
NEFF's N 90 compact combi-steam oven adds Steam Function Plus at 120 degrees to twenty-three heating modes, bringing full flavour-and-texture cooking to a 45 centimetre niche.
The C24FS31G0B is an N 90 built-in compact combi-steam oven in Graphite-Grey, designed for the 45 centimetre niche above or beside a main oven, or as a capable second cavity in a well-planned kitchen. Its 47-litre interior offers twenty-three heating functions controlled from a TFT touch display, with Home Connect Wi-Fi built in.
Steam is what it is really about. Steam Function Plus works at up to 120 degrees, cooking dishes faster while helping them retain more vitamins and nutrients, and steam can be combined with CircoTherm, conventional heat, hot air grilling, warming and the bread baking setting, so a roast chicken stays juicy inside while the skin crisps.
Ideal For
Steam cooking at up to 120 degrees helps vegetables, fish and grains keep more of their vitamins, nutrients and texture than dry heat alone.
Steam combined with the bread baking setting delivers the moist early bake that gives loaves a proper crust, with defrost and regeneration modes for later.
In a compact 45 centimetre niche it adds a full extra cavity with twenty-three functions, taking pressure off the main oven when hosting.
Key Features
Steam cooking at up to 120 degrees cooks dishes faster while helping them hold on to more of their vitamins and nutrients.
From CircoTherm, bottom heat and two grill widths to defrost, regeneration, low temperature cooking, pizza and bread baking settings.
Steam combines with CircoTherm, conventional heat, hot air grilling, warming and bread baking, pairing moisture with browning in one programme.
A usable, family-relevant capacity in a 45 centimetre niche format, supplied with three steam containers, a grid and a universal pan.
App control, Cooking Assistant, recipes sent to the oven, notifications and voice commands via Amazon Alexa or Google Assistant.
A removable tank feeds the steam system and lifts out for easy filling at the tap, no plumbing connection needed.
What steam actually does for food
Dry oven heat is good at browning but hard on moisture; steam is the reverse. Steam Function Plus works at up to 120 degrees, surrounding food with moist heat that cooks quickly while helping preserve vitamins, nutrients and texture. Vegetables keep their bite and colour, fish stays delicate, rice and grains cook evenly. Regeneration mode reheats plated food gently so yesterday's dinner comes back moist rather than leathery, and defrost handles frozen ingredients with similar care.
The combi part is the clever part
Pure steam is only half the story. This oven combines steam with its hot-air modes, CircoTherm, conventional heat, hot air grilling, warming and the bread baking setting, so you get moisture and browning in the same cook. That is the technique behind bakery crusts: steam early in the bake lets the loaf expand fully before the crust sets and shines. It is equally transformative for roast chicken and reheated pastry. With twenty-three functions in total, from pizza setting to low temperature cooking, the compact cavity concedes very little to a full-size oven.
Compact format, complete oven
At 45.5 centimetres high, the C24FS31G0B fits a compact niche, stacking neatly above a full-size oven or sliding into a bank of tall units at eye level. The 47-litre cavity is supplied properly: a grid, a universal pan and three steam containers, two punched for steaming and one unpunched for collecting juices or cooking rice. The 1.0-litre water tank lifts out for refilling, so no plumbing is required. A TFT touch display runs everything at the oven, while Home Connect adds app control, the Cooking Assistant, Recipe World settings, notifications and voice control through Amazon Alexa or Google Assistant.

The Verdict
Strengths
- Steam Function Plus at up to 120 degrees
- Twenty-three functions including defrost and regeneration
- Steam combines with five hot-air heating modes
- Three steam containers, grid and pan included
- Removable 1.0-litre tank, no plumbing needed
- Home Connect app, recipes and voice control
- Compact 45 centimetre niche format
Considerations
- It fits a 45 centimetre compact niche, not a standard single-oven aperture, and the 47-litre cavity is smaller than a full-size oven's.
- The steam system draws from a 1.0-litre removable tank, which needs refilling by hand for steam cooking sessions.
- There is no plug on the appliance; it needs a hardwired 16 A connection installed by a qualified electrician, and the Air Fry tray is sold separately.
