Immersion blenders can handle hot liquids up to about 190°F (88°C).
- Always submerge the blade fully and keep it below the surface to prevent splashing.
- Let boiling liquids cool for a few minutes before blending to avoid damage.
- Stainless steel shafts are more heat-resistant than plastic ones.
What Are the Risks of Blending Hot Liquids?
Blending hot liquids creates steam and pressure, which can cause splatters. Hot soup can burn your skin if it splashes out. The heat can also damage the blender's plastic parts over time. Some models have a maximum temperature rating, often around 190°F (88°C). Exceeding that may warp the shaft or melt the seal.
How to Safely Blend Hot Soup with an Immersion Blender
Start by letting the liquid cool slightly below boiling. Submerge the blender head fully before turning it on. Keep the blade below the surface to avoid sucking in air and causing splashes. Tilt the blender slightly and move it in an up-and-down motion. Use a deep, narrow pot to minimize splatter. Never fill the pot more than halfway.
Which Immersion Blenders Are Best for Hot Liquids?
Look for models with a stainless steel shaft and a heat-resistant motor housing. The Breville Control Grip has a 1200-watt motor and a 19-inch shaft, ideal for hot pots. The Cuisinart Smart Stick is another solid choice with a 300-watt motor and a detachable shaft. Both have a temperature limit of around 200°F (93°C).
Can You Blend Hot Liquids in a Regular Blender Instead?
A countertop blender can handle hot liquids, but you must vent the lid to release steam. Start at low speed and gradually increase. The heat can crack the glass jar if it's cold. Immersion blenders are safer because you can blend directly in the pot, avoiding transfers. For large batches, a countertop blender may be more convenient.
What About Blending Hot Liquids in a Food Processor?
Food processors are not designed for hot liquids. The heat can cause the plastic bowl to warp and the lid to pop off. If you must use one, let the liquid cool to room temperature first. For hot soup, an immersion blender is the better tool. It's designed for hot use and easier to clean.
