What Ingredients are in Middle Eastern Red Lentil Soup?
Middle Eastern red lentil soup, also known as “Adas,” is a comforting, protein-packed dish that’s been a staple in Middle Eastern cuisine for centuries. It’s remarkably simple to make, requiring just a handful of basic ingredients that create a surprisingly complex flavor.
The beauty of this soup lies in its simplicity—the humble lentil transformed into something truly special with just the right spices and a squeeze of fresh lemon.
- 2 cups red lentils, rinsed and drained
- 6 cups water
- 1 medium onion, chopped
- 1 teaspoon ground cumin
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- Juice of 1 lemon
- Optional garnishes: chopped parsley, diced onions, lemon wedges
When shopping for this recipe, look for split red lentils, which cook faster and break down more easily than their whole counterparts. They’re typically available in the dried bean section or international foods aisle of most grocery stores. Don’t be tempted to substitute brown or green lentils here—they have a different texture and cooking time, and won’t give you that signature creamy consistency that makes Middle Eastern lentil soup so comforting.
And while the ingredient list is short, fresh lemon juice makes a world of difference compared to bottled, providing that bright, zingy finish that balances the earthy lentils perfectly.
How to Make this Middle Eastern Red Lentil Soup

Making this comforting red lentil soup couldn’t be simpler. Start by thoroughly rinsing 2 cups of red lentils under cold water until the water runs clear, then drain them well. Place the lentils in a large pot and add 6 cups of water. Bring this mixture to a boil over medium-high heat. During the initial boiling phase, you’ll notice foam rising to the surface—this is completely normal. Just skim it off with a spoon as needed for a clearer, more refined soup.
Once boiling, add 1 chopped onion, 1 teaspoon of aromatic cumin, 1 teaspoon of salt, and 1/2 teaspoon of black pepper to the pot. Give everything a good stir to distribute the spices evenly. Now comes the magic of slow cooking—reduce the heat to medium-low and let the soup simmer gently for about 45 minutes. The lentils will gradually break down, creating that signature creamy texture that makes this soup so satisfying. Remember to stir occasionally to prevent sticking, and don’t hesitate to add a splash more water if the soup becomes too thick for your liking.
For authentic results, consider using traditional cookware from an Indian cooking appliance set which can enhance the flavor development of this Middle Eastern soup. Right before serving, squeeze in the juice of 1 whole lemon, which brightens all the flavors and gives the soup its characteristic tangy finish. Want to take it up a notch? Serve with little bowls of chopped fresh parsley, diced raw onions, and extra lemon wedges so everyone can customize their bowl.
Middle Eastern Red Lentil Soup Substitutions and Variations
Looking to customize this classic soup to suit your pantry or preferences? I’ve got plenty of ways to make this Middle Eastern staple your own. Try swapping the water for vegetable or chicken broth for deeper flavor. Not a fan of cumin? Coriander or a pinch of cinnamon works beautifully instead.
For heartier variations, I recommend adding diced carrots, celery, or even a handful of spinach during the last few minutes of cooking. A dollop of yogurt on top creates a creamy contrast to the earthy lentils.
Can’t find red lentils? Yellow split peas will work in a pinch, though they’ll need about 15 minutes more cooking time. And for those who enjoy heat, a sprinkle of Aleppo pepper or cayenne really wakes up the flavors.
What to Serve with Middle Eastern Red Lentil Soup
Three perfect accompaniments can transform this humble lentil soup into a complete feast. I always recommend warm, pillowy pita bread for dipping into that cumin-scented broth—nothing better than soaking up every last drop. A simple side salad with cucumber, tomato, and a light vinaigrette adds a refreshing, invigorating crunch that balances the soup’s heartiness.
For a truly authentic experience, serve with a small plate of briny olives and tangy pickled vegetables. These sharp flavors cut through the richness of the lentils, creating a perfect bite each time. Need something more substantial? A scoop of fluffy basmati rice or bulgur wheat transforms this soup from starter to main course. Isn’t it amazing how the simplest additions can elevate a bowl of soup?
