Lentils are a wonderfully nutritious and budget-friendly soup ingredient. You can also try them in this Red Lentil Curry Soup Chickpea Lentil Soup, Kale Lentil Soup and Vegan Red Lentil Tomato Soup.
Ingredient Notes
- Lentils: Use brown or green lentils, as they hold their shape well and cook in about 20 minutes. You can use red lentils; however, they will break down and soften more during cooking so the soup will have a different texture.
- Onion: White or yellow onion is best here.
- Potatoes: Yellow potatoes are suggested. Feel free to use russet, red potatoes, or even sweet potatoes for a slightly sweeter flavor. Peel the potatoes if using russet potatoes or sweet potatoes to remove the thicker skins.
- Vegetables: The classic trio of onion, carrots, and celery creates a flavorful base. If you’re missing one, increase the amount of the others or add diced bell peppers. You can also add cauliflower.
- Greens: Swiss chard or kale works wonderfully, adding color and nutrition. Spinach, collard greens, or arugula can be used instead. Add delicate greens like spinach towards the end to prevent overcooking.
- Spices: If you don’t have smoked paprika, regular paprika works. The spice blend is curry-inspired but you could use Italian spices like thyme, rosemary and oregano for a variation.
- Soy Sauce: Tamari is a great gluten-free option. Coconut aminos can also be used for a soy-free alternative.

Step 5: Place the swiss chard or kale on top of the soup. Cover and let the greens steam for 2–3 minutes until they are tender and bright green.

I added a few different seasoning and left out garlic and substituted the soy sauce with Coconut Aminos. It tasted great and my son liked it as well ☺️
Good soup on a cold day
I accidentally added barley instead of lentils and it still tastes great.
Good to know! Thanks!
Wonderful comforting soup! I loved the addition of fresh parsley as it added so much flavor. I made it in the pressure cooker. 8 min, 10NPR, with a bit less broth.
Thanks for trying it! Good to know for the pressure cooked, haven’t tried that yet.
