Author Notes

A long cooking time allows the spices to work their way into the lentils and vegetables, creating a fragrant soup. If you make it ahead, the flavors will have more time to develop.

Made as is but, didn't add the water. Added twice the spices, not cinnamon. No salt was needed. Didn't add the spinach, no room in the crockpot. Added 1/2 of a large zucchini. Flavor was really good!

What a flavor bomb. And healthy too! I wouldn't change anything. I could see how maybe sauteeing the onion and garlic and roasting the cauli before might intensify the flavors but honestly, I felt there was enough flavor there. And really easy to put together. I love recipes like this that have the flexibility to dial up or down the seasonings. Added a dash of red pepper flakes to my bowl and loved the extra kick.

This is absolutely one of my all-time favorite soups! I followed the directions and found them to be totally perfect! I served this for a small dinner party, and everyone really enjoyed it. This and a serving of rosemary focaccia bread with fresh fruit for dessert made a healthy, fun meal! Thanks for posting this!

So I made this and was not thrilled so I tweaked it and now it is a favorite. I have an All Clad slowcooker so the insert comes out. I placed the onions and carrots and sautéed them for 15 minutes. I then added the minced garlic and all the spices which I aded much more of except the cinnamon. I also added 3/4 teaspoon of Haressa. While this was going on I roasted the cauliflower at 400 in the oven with olive oil and salt and pepper. I added the diced tomatoes, the tomato paste and only chicken stock, no water. I let it come to a simmer and then added Umbrian Lentils as that is all I had. I then added the crisp roasted cauliflower and gave a good mix. I seasoned it with a bit more salt and fresh ground pepper and placed it in the slow cooker for 8 hours on low then I added some spinach, baby kale and torn mint leaves and let cook for 30 more minutes. I let it cool and had it for lunch today and it was spectacular. It is well worth investing time in the vegetables and spices.

Thanks for commenting with the great additions & changes. I also have a slow cooker with insert, and I took yours & tweaked it with great success!

Pretty bland, even after doubling the spices.

Have made this healthy and easy soup several times. My mother used to add to her lentil soups some yeast so I added 2 cups of beer au lieu of water, also more spiced to give the soup the true Moroccan taste. So I, too increased all the dry spices by 1/ 1/2 times. Thank you for this wonderful and flavorful soup!

I'm rating it 5*

I wish I'd read this before I made it; found it to be lacking in flavor as written. Also found it to be quite thin.

This was really good, but on the second time around I would up the amount of spices. I could taste them, but not as strongly as I would have liked. Otherwise, nice and healthy recipe!
