Can I use red lentils instead of brown or green?

Absolutely! Red lentils cook more quickly and break down more readily, creating a creamier, less textured soup. If using red lentils, reduce the cooking time to about 20-25 minutes and watch carefully to prevent overcooking.

How can I make this soup in a slow cooker?

This recipe adapts beautifully to a slow cooker. Sauté the vegetables as directed, then transfer everything to your slow cooker. Cook on low for 7-8 hours or on high for 4-5 hours until the lentils are tender. Blend partially before serving.

Is this soup gluten-free?

Yes! All ingredients in this recipe are naturally gluten-free. Just be sure to check your vegetable broth label to confirm it doesn't contain any gluten additives if you have celiac disease or severe sensitivity.

My soup seems too thick. How can I adjust the consistency?

Lentils continue to absorb liquid as they sit, so it's normal for the soup to thicken over time. Simply add more vegetable broth or water when reheating until you reach your desired consistency. Adjust seasonings if needed after adding extra liquid.

How to Make Lentil Soup

Step 1: Sauté the Aromatics

Heat the olive oil in a large Dutch oven over medium heat. Add the chopped onion, carrot, and celery along with the salt. Cook until the onions become translucent and vegetables begin to soften, about 6-7 minutes. This step builds the flavor foundation, so don’t rush it!

Step 2: Add Remaining Ingredients

Add the rinsed lentils, diced tomatoes, vegetable broth, apple cider vinegar, and all the spices (coriander, cumin, garlic powder, and paprika) to the pot. Stir everything well to combine all ingredients evenly.

Step 3: Bring to a Boil

Increase the heat to high and bring the mixture just to a boil. You’ll see bubbles start to form actively on the surface of the soup.

Step 4: Simmer Until Tender

Reduce the heat to low, cover the pot, and let the soup simmer gently until the lentils become tender, approximately 35-40 minutes. The lentils should be soft but still hold their shape.

Step 5: Blend to Desired Consistency

Using an immersion blender, partially blend the soup to your preferred texture. For a heartier soup, blend just briefly to keep plenty of whole lentils and vegetable pieces intact. For a smoother soup, blend longer.

Pro Tips for Making the Recipe

Choose the right lentils: Brown or green lentils work best for this soup as they hold their shape well. Red lentils will break down more quickly and create a creamier texture.
Don’t skip the sauté: Taking time to properly sauté the vegetables develops essential flavor compounds that make the soup taste rich and complex.
Partial blending: The beauty of this soup is in its texture – blending just some of the soup creates the perfect balance between brothy and hearty.
Taste before serving: The flavor develops as it cooks, so always taste the finished soup and adjust seasonings if needed before serving.
Let it rest: Like many soups, the flavors improve after sitting for a bit. If you have time, let it rest for 15-20 minutes before serving.

How to Serve

This lentil soup shines as a standalone meal, but there are many ways to elevate your serving:

Garnishes

A dollop of Greek yogurt, a sprinkle of fresh herbs like parsley or cilantro, or a drizzle of good olive oil takes this soup to the next level.

Side Pairings

Serve with crusty bread or garlic toast for dipping – there’s nothing better than soaking up that flavorful broth! A simple green salad with vinaigrette makes for a perfect complete meal.

Make It a Feast

For heartier appetites, serve smaller portions of the soup as a starter, followed by a main dish like a roasted vegetable sandwich or grilled cheese.

Make Ahead and Storage

Storing Leftovers

This soup stores beautifully in airtight containers in the refrigerator for up to 5 days. In fact, many people find it tastes even better the next day as the flavors continue to develop!

Freezing

Portion the cooled soup into freezer-safe containers, leaving some room for expansion, and freeze for up to 3 months. Label with the date so you know when to use it by.

Reheating

Thaw frozen soup overnight in the refrigerator. Reheat gently on the stovetop over medium-low heat, stirring occasionally. Add a splash of broth or water if the soup has thickened too much during storage.
