What you will need
This recipe uses 6 simple ingredients that you can find at any grocery store:
- 1.5 cups red lentils rinsed
- 2 medium carrots diced
- 1 large zucchini diced
- 5 cups vegetable broth
- 1 can diced tomatoes 14 oz
- 2 teaspoons ground cumin
Step by step instructions
Step 1: Combine All Ingredients
Add the rinsed red lentils diced carrots zucchini canned diced tomatoes and ground cumin to the slow cooker. Pour in the vegetable broth and stir everything together. Season generously with salt and black pepper.
Step 2: Cook Until Tender
Cover the slow cooker and cook on low for 6 hours or on high for 3 hours. The lentils will break down naturally and thicken the soup as they cook. There is no need to soak red lentils before cooking.
Step 3: Blend for Creaminess
For a creamier texture use an immersion blender to partially blend the soup directly in the slow cooker. Blend about half of the soup and leave the rest chunky for a satisfying texture contrast.
Step 4: Adjust and Serve
Taste the soup and adjust seasoning with salt cumin and a squeeze of fresh lemon juice. Serve hot topped with a drizzle of olive oil fresh parsley and crusty bread on the side.
Easy substitutions
Missing an ingredient? Here are some swaps that work perfectly:
- red lentils → green lentils which hold their shape better for a chunkier soup
- zucchini → spinach stirred in during the last 30 minutes of cooking
Common mistakes to avoid
Watch out for these pitfalls that can affect your results:
- Not rinsing the lentils before cooking which can make the soup taste bitter or gritty
- Adding too little liquid since lentils absorb a significant amount of broth as they cook
