Diet lentil soup is usually made by simmering lentils with onion, carrots and stock or water, then blending until smooth. Keep the added oil modest and skip a flour-and-fat roux for a lighter soup that still gets body from the lentils.
Red lentils are commonly used for diet lentil soup because they cook quickly and blend into a smooth texture. Green or brown lentils also work, but they stay firmer and give the soup a more textured, less creamy finish.
Diet lentil soup can support a filling meal because lentils provide fiber and plant protein. It does not cause weight loss on its own; portion size and what you serve with it still matter.
To thicken diet lentil soup without flour, blend some or all of the cooked lentils and return them to the pot. You can also simmer the soup uncovered so excess liquid evaporates, rather than adding cream or a flour-based thickener.
Yes, diet lentil soup freezes well. Cool it, portion it into airtight freezer-safe containers, and leave a little room for expansion. Thaw it in the refrigerator and reheat thoroughly, stirring to bring the texture back together.
Diet lentil soup generally keeps for up to three days in a covered container in the refrigerator. Cool and refrigerate it promptly, then reheat only the portion you plan to eat rather than repeatedly warming the whole batch.
Diet lentil soup pairs well with a green salad, lemon, or a slice of whole-grain bread. For a more substantial meal, serve it with a simple protein-rich side; avoid relying on fried toppings if you want to keep the meal light.
Yes, you can make diet lentil soup without a blender, though it will be less smooth. Cook the lentils until very soft and mash them against the side of the pot with a spoon or potato masher.
Yes, diet lentil soup works well for meal prep because it can be cooked in a batch and portioned for later meals. The soup may thicken as it sits, so stir in a little water or stock when reheating if needed.
Diet lentil soup can cause gas for some people because lentils contain fiber and fermentable carbohydrates. Cooking the lentils until very soft and starting with a smaller serving may make the soup easier to tolerate.

Diet lentil soup is a lighter take on Turkish lentil soup, usually made by simmering red lentils with onion and often vegetables such as carrot, then blending until smooth. Compared with richer versions, it is prepared with less oil. The soup is mild and earthy, with a creamy texture and seasoning that may include cumin or black pepper. In Turkey it is commonly served hot with lemon, as a simple lunch or supper, sometimes alongside bread or salad. Elsewhere, it also works as an easy plant-based meal or starter. Lentils contribute fibre and plant protein; this version has 0.8 g of fat per 100 g. Serve with a crisp salad, or add a little bread if you want a more substantial meal.
High
How many vitamins, minerals and how much fiber this food carries per calorie. A high score means a lot of nutrition for few calories.
Medium
An EatBetter score computed from fiber, protein and calorie density. A high score means staying full longer on the same calories.
Both scores are calculated per 100 g and do not change with the selected portion. The satiety score is EatBetter's own calculation, not a clinical measure.
