Use an immersion blender by fully submerging the blade before turning it on, then moving it slowly through the food at a slight angle.
An immersion blender turns a pot of soup into a silky puree without transferring hot liquids to a countertop blender. The technique is simple once you know the correct order: submerge, start low, then move slowly. One wrong step — like powering on before the blade hits the liquid — sends soup across the kitchen. The fix for splatter and uneven results is a consistent method that works on nearly every model.
Step-By-Step: How To Use An Immersion Blender Properly
The right technique comes down to five moves that keep blending smooth and splatter-free. Each step below works for corded and cordless models alike.
- Choose a deep, stable container. A pot or tall mixing bowl works best. KitchenAid advises a container about ⅔ full for even blending and proper circulation.
- Submerge the blade completely before powering on. The blade guard must sit fully below the surface. Turning it on while the blade is exposed is the number one cause of splashing.
- Start on low speed. Begin at the lowest setting, then increase gradually once the food begins to break down. For hot soup, low speed also prevents erupting steam and liquid.
- Move slowly through the food. Keep the blade under the surface and work in gentle up-and-down motions or small circles. A slight angle of about 10° reduces the whirlpool effect that causes splashing.
- Turn it off before lifting it out. Always release the power button while the head is still submerged, then lift. This stops liquid from spraying as the blade exits.
Rinse the blade end immediately after use. If the shaft detaches, remove it for cleaning as your model’s guide allows—many are dishwasher-safe, but check the manual to be sure.
Manufacturer Techniques: What Vitamix, KitchenAid, And Breville Say
Different brands add slight variations to the core method. Knowing them helps you match the tool to the texture you want.
Vitamix’s owner’s manual instructs users to press and hold the On/Off Button to start on Speed 1, then rotate the Speed Select Dial to Speed 2. Keep the blender moving, including up and down, for about 90 seconds or until the desired consistency appears. That timing gives you a reliable benchmark for a fully pureed soup.
KitchenAid recommends a slight angle for smooth purees — tilting the head as you move it through the food breaks up chunks more efficiently. For a “smooth & chunky combo” texture, use a 2-second interval method: pulse the blender on for two seconds, off for two seconds, until the mix has both creamy and textured pieces. Breville takes a different approach: start with only the bottom half of the head submerged at low speed, then immerse more of the head and increase speed as ingredients puree. That method works well for dense or fibrous foods that resist blending.
Common Mistakes That Cause Splatter And Uneven Results
Most frustration with an immersion blender comes from fixable habits. The table below shows the error and the correction side by side.
| Mistake | Why It Fails | Fix |
|---|---|---|
| Powering on before submerging | Blade hits air, flinging liquid outward | Submerge fully, then press start |
| Shallow or unstable container | Food splashes over the rim; blade guard not covered | Use a tall pot or bowl, about ⅔ full |
| Starting at high speed | Creates a vortex and violent splatter | Start low, increase gradually |
| Lifting while running | Blade sprays liquid as it exits | Turn off, then lift out |
| Holding perfectly vertical in a big pot | Creates a whirlpool that splashes | Tilt to a 10° angle |
Blending hot soup demands one extra rule: remove the pot from the heat source before you start. Good Housekeeping notes the same guidance — cool the food slightly after taking it off the burner, then blend. Steam and boiling liquid can burn you through the splatter or even force hot soup up the shaft.
Safety Rules: What To Never Do
The immersion blender’s motor lives in the handle, so keep that entire section dry. Never submerge the handle or motor housing, and keep your fingers clear of the blade while the shaft is attached. For hot liquids, the cooling step is not optional: letting soup sit for a few minutes after removing it from the heat protects both your skin and the motor’s seals. If your model came with a whisk or chopper attachment, use the correct guard to avoid scratching cookware.
For cordless models, the technique stays identical — the only difference is the battery. If you’re deciding between corded and cordless, our tested roundup of the best battery immersion blenders compares runtime, power, and real-world performance side by side.
Model-specific limits — like maximum immersion depth or continuous run time — always override general advice. Check the manual that came with your unit before pushing it past its rated use.
