Best Soups to Make With an Immersion Blender
An immersion blender turns a pot of cooked vegetables or legumes into velvety soup in about thirty seconds, with no countertop blender, no hot-liquid transfers, and no extra dishes.
Immersion blenders are built for soup. You cook your ingredients in one pot, lower the blending shaft into the liquid, and blend directly in the same vessel. That means fewer spills, faster cleanup, and no risk of a countertop blender lid popping off from steam pressure. Whether you want a completely smooth bisque or a lightly textured vegetable soup, the technique is the same. The soups below work especially well because their ingredients blend into a uniform consistency and their flavors hold up under heat.
Classic Tomato Bisque
Tomato bisque is probably the most popular immersion blender soup because canned or fresh tomatoes break down quickly into a silky puree. Start with olive oil, onion, garlic, and a large can of crushed or whole tomatoes, then simmer for about twenty minutes until the onion is fully soft. Add a splash of heavy cream or coconut cream, then blend directly in the pot until smooth. The acid in the tomatoes thins the mixture enough that even a mid-range blender with 200 to 300 watts handles it without strain. Taste for salt and a pinch of sugar to balance the acidity before serving.
Butternut Squash Soup
Butternut squash becomes completely smooth when roasted or simmered until tender, which makes it ideal for immersion blending. Peel and cube the squash, cook it in chicken or vegetable broth with a halved onion and a few garlic cloves until a fork slides through with no resistance, then blend until creamy. The natural starch in the squash gives the finished soup a thick, almost velvety body without any added cream. A small amount of fresh ginger or a pinch of nutmeg adds depth. Because the mixture is dense, use a blender with at least 250 watts and keep the shaft fully submerged to avoid splatter.
Red Lentil Soup
Red lentils dissolve as they cook, which means they need very little blending to become smooth. Simmer red lentils with onion, garlic, cumin, turmeric, and broth for about twenty-five minutes until the lentils are completely broken down. A quick pass with the immersion blender, thirty seconds or less, turns the soup from grainy to silky. You can blend only half the batch if you prefer a chunkier texture. Red lentil soup is also one of the easiest to make in a large batch because it freezes well and reheats without separating.
Potato Leek Soup
Potato leek soup relies on the starch in cooked potatoes to create a creamy texture without any cream at all, though cream or butter can be stirred in at the end if you like. Sweat sliced leeks in butter until soft, add cubed Yukon Gold potatoes and broth, and simmer until the potatoes are completely tender, about twenty minutes. Blend directly in the pot. One important note: do not over-blend starchy soups because the cell walls in potato starch can break down too much and turn the soup gluey. A few pulses or a short continuous blend of fifteen to twenty seconds is usually enough.
Roasted Red Pepper Soup
Roasted red peppers, whether jarred or freshly charred and peeled, blend into a bright, slightly smoky soup with very little effort. Saute onion and garlic in olive oil, add the roasted peppers and a cup of broth or tomato juice, simmer for ten minutes, then blend until smooth. Smoked paprika or a small amount of chipotle in adobo deepens the flavor. The relatively thin consistency of this soup means it blends quickly and evenly. Stir in a spoonful of cream cheese or Greek yogurt after blending for richness, since dairy added before blending can sometimes separate under heat.
Carrot Ginger Soup
Carrots are naturally sweet and become very smooth once fully cooked, pairing well with fresh ginger, orange zest, or coconut milk. Simmer peeled, sliced carrots with onion, garlic, fresh ginger, and broth until the carrots are completely soft, at least twenty-five minutes on a medium simmer. Blend until no fibrous bits remain, which may take a full minute with a lower-wattage blender. Adding a splash of orange juice or a can of full-fat coconut milk just before blending gives the soup a bright, rounded finish. This soup stores well in the fridge for four to five days and is one of the easiest to scale up for meal prep.
Tips for Better Results With Any Soup
Keep the blending shaft fully submerged while the motor is running to prevent hot liquid from spraying upward. Tilt the pot slightly so the shaft stays covered even when the soup level drops near the end. Let very hot soups cool for two to three minutes before blending if the pot is nearly full, since steam can build pressure against the shaft. Variable-speed blenders give you more control: start on low to break up large chunks, then increase to finish the blend. A model with 15 speeds, like the Breville BSB510XL (rated 4.6 stars across more than 4,000 reviews), gives you fine control over texture. For high-volume cooking, the All-Clad 10942212300 at 600 watts handles large pots of dense soup without slowing down. If you want a reliable everyday option at a lower price, the Mueller MU-HB-02 has over 52,000 reviews and 9 speeds, making it one of the most proven picks at under $40.
Frequently asked questions
Can I blend soup while it is still boiling on the stove?
It is safer to pull the pot off the heat first. Boiling liquid releases steam rapidly, and blending at a full boil can force hot liquid up the shaft and cause burns. Let the soup cool for two to three minutes, or reduce the heat to a low simmer, before blending.
Why does my immersion blender leave lumps in potato soup?
Potatoes need to be completely cooked through before blending. If you can still feel resistance when you press a chunk against the side of the pot, keep simmering. Also, move the blending shaft around the entire pot rather than holding it in one spot, so you catch all the solids evenly.
Can I use an immersion blender for chunky vegetable soups?
Yes. For a partially blended texture, pulse briefly or blend for just a few seconds and then stop. You can also blend only half the soup and stir the unblended half back in, which gives you a soup that has both a creamy base and visible pieces of vegetable.
How do I clean the blending shaft after making soup?
The quickest method is to fill a tall cup or the blending beaker with warm soapy water and run the blender in it for about ten seconds right after use, while residue is still loose. Rinse with clean water. Most shafts are also dishwasher-safe on the top rack, so check your model's manual if you prefer that method.
Does blender wattage matter for soup?
It matters more for dense soups like thick lentil or squash than for thinner broths. A 150 to 200-watt blender handles most home soups, but you may need to blend in shorter bursts and move through the pot more slowly. For thick, starchy soups or larger batch sizes, a 400 to 600-watt motor finishes the job faster and more evenly.
