• Best blenders for soups and hot liquids: If you regularly blend hot soups or sauces, investing in a high-performance blender is worth it. Models like the Vitamix 5200 and the Breville Super Q are designed with high-heat resistance and feature powerful motors that make quick work of even the hottest liquids.

Why Certain Blenders Struggle with Hot Liquids

Understanding why some blenders struggle with hot liquids can save you from a mess in the kitchen. The main issue lies in the pressure build-up that occurs when hot liquids create steam inside the sealed blender jug.

• Why can’t you blend hot liquids in some blenders? Many blenders aren’t equipped with vented lids, meaning the steam has nowhere to escape. As the heat increases, so does the pressure inside the jug, causing the lid to fly off and hot liquid to splatter. Blenders with non-heat-resistant jugs, like those made from regular plastic, are especially prone to warping and cracking when exposed to high temperatures.
• Can you blend boiling liquids? Blending boiling soup or liquid directly from the stove is generally not recommended unless you’re using a blender that is specifically designed for such tasks. Blending hot liquids at boiling point can lead to a rapid steam explosion, creating hazardous conditions. Always let the liquids cool for a few minutes, and never fill the blender more than halfway.

Hand Blenders and Immersion Blenders for Hot Liquids

If you prefer to avoid transferring hot liquids to a traditional blender, immersion blenders (also known as hand blenders) offer a convenient and safe alternative.

• Can you blend hot soup with a hand blender? Yes! Hand blenders are designed to be used directly in pots or bowls, making them perfect for blending hot soups and sauces. With no need to transfer hot liquids, immersion blenders reduce the risk of spills and burns. Simply submerge the blender in your pot and blend until smooth.
• Blending hot soups with an immersion blender: When using a hand blender, ensure that the blade is fully immersed in the liquid before turning it on. This helps avoid splashing. Stainless steel immersion blenders are particularly well-suited for hot liquids, as they’re durable and can withstand high temperatures without damage.
• Can I use a hand blender in hot liquid? Absolutely! Just make sure the motor doesn’t overheat. Hand blenders are a great choice for soups, sauces, and even hot drinks, as they blend directly in the cooking pot and eliminate the need for extra cleanup.

Blending Specific Hot Foods and Liquids

Beyond soups and sauces, blenders are versatile enough to handle a variety of hot foods and liquids. But it’s important to know which foods can safely be blended hot, and which require some special attention.

• Blender for hot sauces: Whether you’re making a fiery salsa or a delicate hollandaise sauce, using a blender for hot sauces can save you time and effort. Choose a blender with precise speed control to ensure that the sauce doesn’t overheat or splatter.
• Blending hot coffee in blender: When blending hot coffee or other hot drinks (like bulletproof coffee), always vent the blender to allow steam to escape. Blending hot coffee can create a frothy, rich texture, but it’s essential to manage the steam build-up to avoid messy explosions.
• Can I blend hot soup in my Ninja blender? Yes, but proceed with caution. While some Ninja blenders are capable of handling hot foods, not all are designed for it. Check the user manual to ensure that your model is safe for blending hot soups, and always leave the lid vented.
• Blending hot foods: Foods like steamed vegetables, cooked beans, or warm sauces can be blended hot, but remember to follow the halfway rule: never fill the blender more than halfway with hot liquids to avoid steam pressure build-up.

Hot Food in Plastic Blenders: A Safety Debate

Using plastic blenders for hot liquids is often discouraged due to concerns about chemical leaching and container warping.

• Hot food in plastic blender: Regular plastic containers can warp or release harmful chemicals when exposed to high heat. If you must use a plastic blender, make sure it’s made from BPA-free, heat-resistant plastic to minimize health risks and ensure the container doesn’t melt or crack under the heat.
• Can you put hot liquid in a plastic blender? While some plastic blenders are marketed as heat-resistant, they’re generally not as durable as glass or stainless steel. If your blender is made from plastic, check the manufacturer’s instructions before attempting to blend hot liquids. BPA-free plastic is safer, but even with BPA-free models, allowing liquids to cool slightly before blending is always a good idea.

Common Issues When Blending Hot Liquids and How to Solve Them

Blending hot liquids presents several unique challenges, even if you’re using a high-quality blender. Here are some common issues and how to avoid them:

• Pressure build-up in the blender: As mentioned earlier, blending hot liquids can create pressure inside the container due to steam. Always allow hot liquids to cool slightly before blending, and leave the lid’s center cap off or vent it to allow steam to escape. Starting at a low speed and gradually increasing it will also help reduce pressure build-up.
• Blender splattering: Even with the best precautions, splattering can occur when blending hot liquids. To reduce splatter, don’t overfill the blender (stick to half or less), cover the lid with a towel, and hold the lid down firmly. Blending in small batches is another way to control splattering, especially with larger quantities of liquid.
• Blending hot liquids in a Ninja blender: Ninja blenders, while powerful, don’t always have the heat resistance needed for boiling liquids. If you’re using a Ninja blender, let the liquid cool slightly, and vent the lid to allow steam to escape. Ninja does offer models that are better equipped for hot blending, but always check the manual to be sure.
• Hot liquid leaking from the blender: Older or less durable blenders may not have properly sealed containers. Check the gasket seal of your blender to ensure it’s not worn out, and if you notice leaking, replace the seal. If the blender jug is cracked or warped, it’s time to replace it altogether.

Hot and Cold Blending: What’s the Difference?

Blenders can handle a wide variety of ingredients, but the difference between hot and cold blending goes beyond just temperature. Here’s how hot blending differs from cold blending:

• Blending hot liquids vs. cold liquids: When blending hot liquids, you need to account for steam and pressure build-up, which isn’t an issue with cold ingredients. With cold liquids, the blender can often be filled to a higher capacity, and the risk of splattering is minimal.
• Hot and cold blenders: Some blenders, like the Vitamix Ascent Series, are designed specifically to handle both hot and cold liquids, making them versatile kitchen tools. These models often come with a self-cleaning feature, which is useful after blending hot, sticky foods like soups or sauces.
• Can I blend something hot and cold at the same time? While it’s possible to mix hot and cold ingredients, be cautious with the temperature differential. Extreme temperature changes can cause glass blender jugs to crack and can lead to improper blending.

Blending Hot Liquids for Specific Recipes

Whether you’re blending a velvety smooth soup, a creamy sauce, or even a hot drink, using the right technique will yield better results. Here are some common hot recipes and tips for blending them perfectly:

• Hot soup in blender: Whether you’re making tomato soup, butternut squash soup, or creamy broccoli soup, blending hot soup is one of the most common tasks for high-performance blenders. To avoid steam explosions, let the soup cool slightly before blending, and blend in small batches if necessary.
• Hot sauce in blender: Hot sauces like salsa verde or buffalo sauce require precise blending to get the right consistency. Blenders with variable speed control are ideal, allowing you to adjust the texture from chunky to smooth without over-processing the ingredients.
• Blending hot coffee in a blender: Want to make bulletproof coffee or frothy latte-style drinks at home? While blending coffee can produce a rich and creamy result, take care to vent the blender and start slowly to prevent steam from building up.
• Can I blend hot soup in NutriBullet or Magic Bullet? While these compact blenders are great for smoothies, they’re less suited for hot liquids. If you must use a NutriBullet or Magic Bullet for hot blending, let the soup cool down to a warm temperature to avoid damaging the plastic container.
