Creamy Red Lentil Soup

This creamy red lentil soup is an easy vegetarian dinner recipe that’s ready in under an hour. Serve it with a side salad or fresh bread for a full meal.

How is it that lentils are conspicuously absent from the traditional Midwest American diet? Neither Alex nor I remember eating them much (if ever) as children. It’s a shame, since they’re delicious and bursting with nutrition, not to mention they’re budget-friendly. Just looking at their bright, happy color can cure any case of the blues. One of our favorite ways to eat lentils is in soup, though of course they’re fabulous on nachos and in tacos as well. Here’s a recipe that’s basic but with flavor beyond your dreams: our favorite creamy red lentil soup.

Why red lentils?

Red lentils named as such from their beautiful orange-pink color. Of any of the lentil varieties, the texture of red lentils breaks down the quickest. This makes it perfect for a creamy, pureed soup like this red lentil soup.

Another great recipe with red lentils? This Masoor Dal (Indian Red Lentils). Masoor dal translates as “red lentils” in Hindi. It comes out cozy and nuanced, with just the right amount of gentle flavoring.

Tips for the best red lentil soup

This red lentil soup is incredibly easy to make! Here are a few tips to consider when you make it:

• If time, soak the lentils. If you think of it, soak the lentils in a bowl of water overnight before you make this recipe. Soaking the lentils cuts down the cooking time and means you have less hands-on time to worry about when making this soup.
• Don’t skimp on the garnish. What takes the cake in this red lentil soup recipe is the garnish! The combination of crunchy toasted almonds, fresh cilantro, and tangy lemon juice takes the soup to a new level.
• An immersion blender is helpful, but a standard blender works. To make this red lentil soup extra creamy, puree the mixture using an immersion blender. Or, use a regular blender and be careful when pouring the hot soup in! If you don’t have access to a regular blender, just eat this soup chunky!

You could also experiment with grating the onion, garlic, and carrots before cooking them to make this soup smoother. And instead of diced tomatoes, you could use pureed tomatoes (just make sure they’re plain tomatoes without added seasonings). We’ve only ever made this red lentil soup with our immersion blender, so I can’t speak to how well these swaps will work, but I imagine the flavor will be just as good!

How to store red lentil soup

This vegan lentil soup reheats incredibly well and can be enjoyed for days after you first served it. Honestly, the flavor gets better the longer this soup sits in the fridge! To store this red lentil soup, let it cool almost to room temperature on your counter before spooning it into a sealed container. It will keep in the fridge for up to 5 days.

You can also freeze this red lentil soup in mason jars or single-serving containers and reheat it in the microwave as a quick grab-and-go lunch. Or pop the mason jar of frozen soup into your lunchbox, and take it to work!

We enjoyed this as a first course for a lovely dinner with friends, but I know we’ll be making it again soon for an easy weeknight dinner. Since the leftovers reheat well, it is also a great option to take to work for lunch.

Need an immersion blender?

An immersion blender is also called a “stick blender” or hand blender. It’s useful for making pureed soups like this red lentil soup because you can place it right into the pot instead of transferring hot soup to a blender and then back.

Description

This creamy red lentil soup is an easy vegetarian dinner recipe that’s ready in under an hour. Serve it with a side salad or fresh bread for a full meal.  

---

Scale 1x2x3x

Ingredients

• 1 1/2 cups red lentils (soaked, if possible)
• 1 yellow onion
• 4 cloves garlic
• 2 carrots
• 3 tablespoons olive oil
• 15-ounce can diced tomatoes
• 3 teaspoons cumin
• 2 teaspoons paprika
• 1/4 teaspoon cayenne pepper
• 1/2 teaspoon kosher salt
• Fresh ground black pepper
• 1 quart vegetable broth
• 1/3 cup sliced almonds
• 1 lemon
• Fresh cilantro, to garnish

---

Instructions

1. If possible, soak 1 1/2 cups lentils prior to cooking: place them in a large bowl and cover with several inches of cold water for about 12 hours. If you don’t have time, this step is optional; the lentils will just need to be cooked a bit longer in Step 5.
2. Chop the onion. Mince 4 cloves garlic. Chop the 2 carrots. Chop a bit of cilantro (if using for a garnish).
3. In a large pot or dutch oven, heat 3 tablespoons olive oil over medium heat. Add the onion, garlic, and carrots and sauté, stirring occasionally, for about 4 minutes.
4. Add the tomatoes, 3 teaspoons cumin, 2 teaspoons paprika, 1/4 teaspoon cayenne pepper, 1/2 teaspoon kosher salt, and a few grinds black pepper. Sauté for 2 minutes, stirring occasionally.
5. Add 1 quart broth and the lentils. Bring to a simmer, then cook until the lentils are soft, 10 to 15 minutes if soaked, or 20 to 30 minutes if unsoaked. When the soup is done, purée it using an immersion blender (or regular blender).
6. While the soup cooks, toast the almonds in a dry pan over medium heat, stirring occasionally until browned, about 3 to 4 minutes (make sure to watch them constantly so they do not burn).
7. To serve, dish the soup into bowls. Garnish with toasted almonds, fresh squeezed lemon juice, fresh cilantro, and a drizzle of olive oil.
