Gaggenau Combi-Steam Oven: Getting the Most from Steam Cooking

Gaggenau combi-steam ovens represent the pinnacle of cooking technology. Understanding their steam functions helps you unlock exceptional culinary results.

Understanding Steam Cooking Modes

Full Steam (100% Humidity)

Operating at 30°C to 100°C (86°F to 212°F), full steam is ideal for:

• Vegetables (perfect texture, color retention)
• Fish and seafood (gentle, moist cooking)
• Rice and grains
• Reheating without drying
• Sous vide cooking

Tips:

Use perforated pans for steam circulation

Do not overcrowd the oven

Start with fresh, cold water

Combination Modes

Hot Air with Steam (30-230°C):

Bread baking (crispy crust, soft interior)

Roasting meats (juicy results)

Pastries and pies

Casseroles

Regenerating/Reheating:

Restaurant-quality food revival

Maintains original texture

Prevents drying

Humidity Levels

Gaggenau allows precise humidity control:

• 0-30%: Crispy results, roasting
• 30-60%: Balanced cooking, everyday use
• 60-80%: Moist cooking, breads

Water System Management

Filling the Water Tank

• Remove tank from oven cavity
• Fill with fresh, cold water
• Do not exceed maximum line

Water Quality Matters:

Hard water causes mineral buildup

Distilled water may affect steam generation

Filtered tap water works best
