Tips and Techniques

How to make soup thicker? – Let it cook a bit longer without the lid. You can do this on stovetop to speed it up. This allows excess liquid to evaporate. You can also use a hand-held immersion blender to blend a small portion of the soup to make it thicker.

How to make leftover soup thinner? – Lentils are notorious for soaking up as much liquid as possible, which means you’ll want to add broth or a little bit of liquid to the portion you’re heating up, in order to thin it out again. This will restore its original consistency.

Rinse and drain Lentils – Be sure to rinse and drain your lentils thoroughly before using them to remove debris.

Other lentil options – If you’re unable to get your hands on brown lentils, you can try your hand at green lentils or red lentils. However, it’s important to point out that red lentils dissolve when cooked. Thus, it makes a thicker soup. Green lentils are similar to brown ones and will hold their shape much better. Basically, taste and even overall color will vary, depending on the type of lentils you use.

The importance of fully cooking lentils – Be sure your lentils are soft and tender. All slow cookers will vary on how well they cook at each setting. If your lentils are not tender, allow them to cook for longer until they are soft. Eating under-cooked lentils can make your tummy hurt.

Broth substitute – If you don’t have broth and need a substitute in a pinch, you can use the same amount of water. However, there will be a flavor component missing without the broth.

Use low sodium broth- Because that prevents this meal from becoming too salty.

Adjust amount of seasonings- Use more or less, based on your preference.
