Ingredients

  • ¼ cup olive oil
  • 2 cups small diced yellow onions
  • 1 cup diced carrots (optional)
  • 1 cup diced celery
  • 3 Tbsp chopped or thinly sliced garlic
  • 2 tsp smoked paprika
  • ½ tsp crushed red pepper (optional)
  • 1 (6-ounce) can tomato paste (about ⅔ cup)
  • 8 cups vegetable broth, preferably no- or low-sodium
  • About 1½ pounds sweet potatoes or yams, peeled and small diced
  • 8 ounces red lentils
  • 2 tsp ground cumin
  • 1 tsp ground coriander
  • 8 ounces kale (Tuscan/lacinato/black kale preferred)
  • 1½ tsp salt, or to taste

Instructions

  1. Step 1: Gather and prep all ingredients. Check the lentils for any stones or debris and discard them. Rinse the lentils well under cold running water using a colander.
  2. Step 2: Heat olive oil in a large pot or Dutch oven over medium-low heat. Add diced onions, carrots, celery, garlic, smoked paprika, and crushed red pepper flakes. Stir and cook for about 4 minutes until the vegetables soften, stirring occasionally.
  3. Step 3: Push the vegetable mixture to one side of the pot. Add the tomato paste and cook for about 1 minute, then stir it together with the vegetables.
  4. Step 4: Pour in 2 cups of vegetable broth and stir to loosen and scrape any browned bits from the bottom of the pot.
  5. Step 5: Add the remaining broth, diced sweet potatoes, rinsed lentils, ground cumin, and ground coriander. Stir everything until well combined. Cover the pot and bring to a simmer, stirring occasionally to prevent the lentils from sticking.
  6. Step 6: Simmer the soup partially covered for 10 minutes. Then stir in the kale and continue cooking until the kale, vegetables, and lentils are tender, about 5 more minutes.
  7. Step 7: Season the soup to taste with salt. Turn off the heat and ladle the soup into bowls. Enjoy your warm, nourishing meal!

Tips & Variations

  • For a smoother texture, use an immersion blender to partially puree the soup before adding kale.
  • Swap kale for spinach or Swiss chard if you prefer a milder leafy green.
  • Add a squeeze of lemon juice just before serving to brighten the flavors.
  • Use smoked paprika for a subtle smoky depth, or substitute with regular paprika if unavailable.

Storage

Store leftover soup in an airtight container in the refrigerator for up to 4 days. Reheat gently on the stove or in the microwave, adding a splash of broth or water if it has thickened. This soup also freezes well for up to 3 months; thaw overnight in the fridge before reheating.

How to Serve

A white bowl with black trim is filled with a thick, tomato-based soup that has three main layers. The bottom layer is a rich red-orange broth with a smooth texture. Floating on top are medium-sized chunks of bright orange sweet potato and small slices of carrot.

Some small bits of onion and lentils are mixed within, enhancing the appearance of hearty ingredients. The bowl sits on a white plate with black trim, placed on a white marbled surface with a folded white cloth underneath. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use other types of lentils instead of red lentils?

  • Adjust the crushed red pepper flakes to control the heat level according to your preference.
  • This soup stores well in the refrigerator for up to 4 days and freezes beautifully for up to 3 months.
  • Use low-sodium vegetable broth to better control the saltiness and keep sodium levels moderate.
