Do you have to soak red lentils before cooking? ›

How to prepare lentils. Lentils do not require it but can be soaked in order to reduce cooking time by about half. Before cooking, rinse lentils in cold water, pick over to remove debris or shrivelled lentils, then drain.

Red Lentil to Water Ratio

To cook red lentils so that they retain some of their shape but are still cooked through, use 2 cups water to 1 cup lentils. To cook red lentils so that they break down into a puree, use 3 cups water to 1 cup lentils.

The other good news: Lentils don't need to soak as beans do (though you do need to sort and rinse them before cooking). Different types of lentils cook in different amounts of time. Red lentils are the fastest cooking and they dissolve as they cook and make for a smooth soup.

Be sure to use a large enough saucepan as the lentils will double or triple in size. Bring to a boil, cover tightly, reduce heat and simmer until they are tender. For whole lentils, cook time is typically 15-20 minutes. For split red lentils, cook time is typically only about 5-7 minutes.

Soaking: Unlike beans, lentils are small and cook relatively quick (in general, about 20-30 minutes) so they don't require pre-soaking. However, soaking lentils for a few hours or overnight may improve the digestibility of starches in lentils and an overnight soak can also reduce cooking time by about half.

Here's why soaking lentils is important

Fact 1: Soaking lentils improves digestion and nutrition absorption as it can neutralise lectins and phytates present that may cause gas and bloating. Fact 2: Soaking lentils also reduces its cooking time.

As a general rule, one cup of dried lentils yields two to two-and-a-half cups of cooked lentils. Because of their rather delicate, earthy flavor, lentils work well in a variety of dishes and in almost any type of cuisine. The best time to add flavor to lentils is during the cooking process.

Lentils aren't rice—they don't need to absorb every last drop of cooking liquid. They're more like pasta: best cooked in an abundance of water or stock. Bring your liquid up to a boil, add your lentils, then turn down your heat to a simmer for at least 25-30 minutes.

Mushy, overcooked lentils are far from tasty. Cooking them at a rapid simmer can lead to them splitting their skins from the pressure and thus lead to mushy results. Follow this tip: Trust that a gentle simmer will cook the lentils perfectly.

Yes, you can overcook lentils; they will become mushy. Much depends on the type of lentil you're using. Some cook quicker and hold their shape better than others. To avoid overcooking them, always follow the cooking directions in your recipe and use the type of lentils called for in the ingredient list.

Why won't my lentils soften in soup? ›

You're not using enough water

According to the BBC, lentils need a whole lot of water to cook all of the way through. So use at least three times more water than lentils and avoid the temptation to salt the water. Adding salt can make the lentil's exterior tough and unappetizing (via Lentils.org).

You do have to cook them, although soaking them first can have benefits. It does things to the enzymes that make the lentils less starchy and easier to digest with less gas. If you want them cold for a salad, you'll still have to cook them, then rinse in cool water.

Honestly, the best way to tell if lentils are done are to taste them. They should be tender to the bite, with some varieties of lentils being a bit more firm and others more soft. That said, if you would like your lentils to be softer, just simmer them a few minutes longer until they reaches your desired consistency.

In that book, I advise to soak lentils from four to twenty-four hours and then drain and cook them in the usual three cups of water. This brings the total cook time down to twenty minutes compared with thirty-five, a respectable times savings when you're starting from scratch on a weeknight.

To get a proper soak going, make sure that you pick through your lentils, and give them a cool rinse. Pour your lentils in a large pot and cover them with cold water. Allow to soak for at least 4 hours or overnight and up to 24 hours for best results.

To soak, I generally rinse and then cover with triple the amount of fresh water, leave overnight on the countertop and rinse the next day. Forgot to soak overnight? Try a quick soak: pour over boiling water and leave to sit for 3 hours before rinsing and draining and proceeding with your recipe.

Aim to soak your beans or lentils for at least 4 hours, and preferably overnight. Dump the soaking water (i.e. don't use it to cook the beans). Then be sure to give your beans/lentils a good rinse before cooking to wash away those gas-producing carbohydrates. Introduce them slowly.
