Best lentil soup recipe (2024)

What thickens lentil soup? ›

Add flour or cornflour

Put a tablespoon of either into a small bowl and stir in 2-3 tbsp of the soup until you have a smooth mixture. Stir this back into the soup and bring it to a simmer. Cook for a few minutes to allow the starch granules to burst to thicken, and to cook out any flour flavour.

Why does my lentil soup taste bland? Lentils have a relatively mild taste and take well to seasonings. To avoid a bland lentil soup, use a flavorful broth—whether that's homemade or store-bought chicken or vegetable broth. The other key is building flavor.

Rinse. On occasion, you'll find small rocks or debris mixed in with dried lentils. To avoid eating them, rinse the lentils in a fine mesh sieve and pick them over before you cook them.

Throw in a lot of garlic! Don't forget to add a big pinch of salt (about 1⁄4 teaspoon per serving, or 3⁄4 teaspoon for 1 cup of dried lentils) and a glug of olive oil or a pat of butter for richness. Hot tip: you can also cook the lentils in broth instead of water for more robust flavor.

Avoiding Mushy Lentils

You want to see just a few bubbles in the water and some gentle movement in the lentils. They will plump up nicely without splitting their skins or becoming mushy. The other trick is to wait to add the salt or any acidic ingredients until the lentils are done cooking.

It's important to note that cornstarch has twice the thickening power of flour. If you need to substitute cornstarch to thicken liquid in a recipe that calls for ¼ cup (four tablespoons) flour, you only need two tablespoons cornstarch.

I recommend using green or French green lentils because they hold their shape in the soup, adding satisfying texture. Brown lentils are also a fine option.

As the veggies hit the boiling water, volatile acids are released into the water and are carried away in the steam. When the pot is covered, the steam and the acids it contains are forced back into the water. Once there, the acids react with the chlorophyll in the vegetables, turning them an unsightly shade of brown.

A typical packet doesn't say to rinse them. With red lentils the only reaosn I can see for rinsing is to (slightly) reduce foaming; with Puy lentils and some others even that's not an issue and you may lose flavour.

What pairs well with lentils? ›

If you have a few root vegetables hanging out in your fridge, those are also great with lentils, like in this warm lentil and root vegetable salad with parsnips and carrots. Lentils are particularly nice with cheese, as in this grilled halloumi and lentil salad.

Black Beluga lentils have the most flavor, adding a rich, earthy taste and a firm texture that holds up well during cooking. Black lentils will be ready in 20–25 minutes; however, they will fall apart like their brown, green, and red partners once you cook them for too long.

If you've made a soup and think it looks a little runny, you can add a thickening agent, such as starch, to adjust the consistency or add chopped vegetables to bulk up a thin broth.

To retain some texture but thicken the dish, you can use a cornstarch slurry or simply add some potato flakes, a couple of tablespoons at a time. Neither method will add any appreciable taste. If you cooked them correctly they should be plenty thick.

Add Flour Or Cornstarch

You can thicken soup by adding flour, cornstarch, or another starchy substitute.

Lentils: The star of the soup, lentils are nutritious and hearty, thickening the soup while adding texture and protein. While common brown or green lentils will work, French lentils are preferred for their peppery flavor and firm texture that holds up well during cooking.
