Onions are a fundamental ingredient in many cuisines around the world. They add flavor, texture, and a punch of nutrients to various dishes. However, working with onions can be a challenge, especially when it comes to chopping and storing them. If you’re wondering whether you can blend onions and keep them in the fridge, the answer is yes, but there are some things to consider.
Understanding Onions and Their Properties
Before we dive into the world of blended onions, it’s essential to understand the properties of onions and how they behave when chopped, blended, or cooked. Onions are made up of cells that contain sulfur compounds, which are responsible for their pungent flavor and aroma. When onions are chopped or blended, these cells are broken down, releasing the sulfur compounds into the air. This is why onions can make you cry when you chop them.
Onions are also high in water content, which can affect their texture and shelf life when stored. The water content in onions can cause them to become soggy or develop off-flavors when exposed to air, heat, or moisture.

Then, add the chopped onions to a blender or food processor with a small amount of water or oil. Blend the onions until they reach your desired consistency, which can range from a smooth puree to a coarse chop.
When blending onions, it’s essential to be mindful of the amount of liquid you add, as too much can result in a too-watery consistency. Start with a small amount of liquid and add more as needed to achieve the desired texture. Additionally, be careful when handling blended onions, as they can be quite potent and may cause eye irritation.
How long can blended onions be stored in the fridge?
Blended onions can be stored in the fridge for up to one week. It’s essential to store them in an airtight container to prevent moisture and other flavors from affecting the onions. When storing blended onions, make sure to press plastic wrap or wax paper directly onto the surface of the onions to prevent air from reaching them.
Before storing blended onions, it’s a good idea to label the container with the date and contents. This will help you keep track of how long the onions have been stored and ensure you use the oldest ones first. When you’re ready to use the blended onions, simply scoop out the desired amount and use it in your recipe.
Can blended onions be frozen for longer storage?
Yes, blended onions can be frozen for longer storage. In fact, freezing is an excellent way to preserve the flavor and texture of blended onions for several months. To freeze blended onions, simply scoop the desired amount into an airtight container or freezer bag, making sure to press out as much air as possible before sealing.
When freezing blended onions, it’s essential to consider the texture and consistency you want to achieve when you thaw them. If you want a smooth puree, it’s best to freeze the onions in a single block. However, if you prefer a coarser texture, you can freeze the onions in ice cube trays and then transfer the frozen cubes to a freezer bag.
How do I prevent blended onions from becoming too watery?
Preventing blended onions from becoming too watery is crucial to maintaining their texture and flavor. One way to prevent this is to use a small amount of liquid when blending the onions. You can also add a pinch of salt to help draw out excess moisture from the onions.
Another way to prevent blended onions from becoming too watery is to cook them slightly before blending. This will help to caramelize the natural sugars in the onions and reduce their moisture content. Additionally, you can try adding a small amount of oil or fat to the blended onions to help bind the mixture together and prevent it from becoming too watery.
Can I use blended onions in any recipe?
Blended onions can be used in a variety of recipes, but they may not be suitable for every dish. For example, if a recipe calls for raw onions, blended onions may not provide the same texture and flavor. However, blended onions are perfect for recipes where cooked onions are desired, such as soups, stews, and sauces.
When using blended onions in a recipe, it’s essential to consider the amount of liquid in the dish. Blended onions can add a significant amount of moisture to a recipe, so you may need to adjust the amount of liquid accordingly. Additionally, you can use blended onions as a flavor booster in recipes, adding a spoonful to enhance the overall flavor.
How do I know if blended onions have gone bad?
Blended onions can go bad if they are not stored properly or if they are past their expiration date. To check if blended onions have gone bad, look for signs of spoilage such as an off smell, slimy texture, or mold growth. If you notice any of these signs, it’s best to err on the side of caution and discard the onions.
Another way to check if blended onions have gone bad is to taste them. If they have a sour or unpleasantly sweet flavor, it’s likely that they have spoiled. When in doubt, it’s always best to discard blended onions and start fresh to ensure the quality and safety of your recipes.
Can I blend other types of onions for storage?
Yes, you can blend other types of onions for storage, including shallots, scallions, and leeks. However, keep in mind that different types of onions may have varying levels of moisture and flavor, which can affect the texture and consistency of the blended onions.
When blending other types of onions, it’s essential to adjust the amount of liquid and seasoning accordingly.

Additionally, you can experiment with blending different types of onions together to create unique flavor profiles and textures.
