Oh, the 6 PM panic. You know the feeling, right? You’re home, you’re tired, and you’re hungry now; the idea of tackling a complicated, multi-step recipe feels absolutely impossible. I have been there more times than I can count. On nights like those, I used to reach for the takeout menus, but my wallet (and my gut) wasn’t always happy about it. That all changed when I finally perfected this recipe: my absolute, hands-down favorite Easy 30-Minute Lentil Soup.
Seriously, this soup is my weeknight secret weapon. It’s not one of those bland, watery lentil soups that feel like a chore to eat. This is a rich, aromatic, and profoundly satisfying soup that tastes as if it has been simmering for hours, not minutes. It’s an actual one-pot meal that happens to be packed with plant-based protein, loaded with veggies, and incredibly cosy.
The magic here is twofold: first, we create a quick yet powerful flavor base with simple aromatics and a trio of perfectly balanced spices. Second, we finish it with a “secret” ingredient that brightens everything up and makes the whole pot sing. It’s the hug-in-a-bowl you didn’t know you needed, and it’s ready before you’d even decide on what to order. Let’s get this done!

Easy 30-Minute Lentil Soup
Ingredients
For the Soup Base:
- 2 tablespoons olive oil
- 1 medium yellow onion finely chopped
- 3 cloves garlic minced
- 2 medium carrots peeled and chopped
- 2 celery ribs chopped
For the Lentil Soup:
- 1 can 14 ounces crushed or diced tomatoes, with juices
- 2 cups dried green or brown lentils rinsed and picked over
- 7 cups vegetable broth
- 1 teaspoon smoked paprika
- ½ teaspoon ground cumin
- ½ teaspoon ground coriander
- 1 teaspoon salt or to taste
For Finishing:
- 3 cups baby spinach sliced into ribbons
- 1 lemon juiced (about 2 tablespoons)
- Additional salt and black pepper to taste
For Serving (Optional):
- Crusty bread for dipping
- Extra lemon wedges
- Fresh parsley chopped
Instructions
- Sauté the Vegetables: Heat the olive oil in a large pot or Dutch oven over medium heat. Add the onion, garlic, carrots, and celery. Sauté, stirring frequently, for 4-5 minutes until the vegetables begin to soften and become fragrant.
- Add Lentils & Seasonings: Add the canned tomatoes (with their juices), rinsed lentils, vegetable broth, smoked paprika, cumin, and coriander. Stir everything together to combine.
- Simmer Until Tender: Increase the heat and bring the soup to a boil. Immediately reduce the heat to low and let it simmer, uncovered, for about 30 minutes. The soup is ready when the lentils are tender (but not mushy) and the soup has thickened. Stir occasionally.
- Add Greens & Lemon: Once the lentils are tender, reduce the heat to low. Stir in the sliced spinach ribbons and the fresh lemon juice. The spinach will wilt in 1-2 minutes.
- Finish & Serve: Taste the soup and season generously with salt and black pepper until the flavors pop. Ladle the hot soup into bowls and serve immediately with crusty bread and extra lemon wedges.
Notes
- For a Creamier Soup: Use an immersion blender to pulse the soup 3-4 times right in the pot. This will partially blend it, creating a creamier texture while still leaving plenty of whole lentils.
-
Lentil Type: This recipe works best with green or brown lentils, as they hold their shape. Red lentils can be used, but they will break down completely and create a much thicker, puree-style soup (and will likely cook in 20 minutes).
Â
- Storage: Store leftovers in an airtight container in the fridge for up to 5 days. The soup will thicken as it sits; simply add a splash of broth or water when reheating. It also freezes beautifully for up to 3 months.

How to Make This Easy 30-Minute Lentil Soup Step-by-Step
Alright, let’s get this going. It’s a straightforward process, so put on some music, grab your favourite pot, and you’ll be enjoying your meal in no time.
①Sauté the Vegetables
Heat the olive oil in a large, heavy-bottomed pot or Dutch oven over medium heat until it’s shimmering. Add your chopped onion, minced garlic, chopped carrots, and chopped celery to the pot. Sauté the vegetables, stirring frequently with a wooden spoon, for about 4-5 minutes. You’re looking for them to begin to soften and become incredibly fragrant. The onions should turn translucent, and your kitchen should start to smell amazing. This step is crucial for building the flavour foundation of your soup, so don’t rush it! This is where all the depth starts.
â‘¡ Add the Lentils and Seasonings
Now, add the canned tomatoes (and all their juices, don’t drain that liquid gold!), your rinsed lentils, the vegetable broth, ground cumin, ground coriander, and that all-important smoked paprika. Stir everything together thoroughly. You want to ensure that all the beautiful spices are evenly distributed and the lentils are fully submerged in the liquid. That combination of earthy cumin, floral coriander, and smoky paprika creates an aromatic base that transforms simple lentils into something really special. Give it all a good stir to ensure nothing is sticking to the bottom.
â‘¢ Simmer Until Tender
This is where the magic happens. Increase the heat and bring the soup to a rolling boil. As soon as it’s boiling, immediately reduce the heat to low and let it simmer gently, uncovered, for about 30 minutes. That’s it! You’ll know it’s ready when the lentils are perfectly tender; they should be soft but still hold their shape, not turn to complete mush. The soup will also have thickened considerably as the lentils release their natural starches into the broth. Be sure to stir it occasionally to prevent sticking.
If your soup gets too thick for your liking, no problem. Add an extra splash of vegetable broth or water to thin it out until it reaches the desired consistency.
My Favourite Texture Tip: For an extra creamy, luscious texture, I love to use an immersion blender and give the soup just a few quick pulses right in the pot. Don’t go crazy; you’re not making a puree! Just 3-4 zaps will partially blend the soup, making it creamier while still leaving plenty of whole lentils and veggies. If you don’t have an immersion blender, you can carefully transfer 1-2 cups to a regular blender, puree until smooth, and stir it back in.
â‘£ Add the Greens and Lemon
Okay, this is the most essential part! Once your lentils are tender, reduce the heat to low. Stir in the sliced spinach ribbons and the freshly squeezed lemon juice. The spinach will wilt almost immediately, so this only takes a minute or two. The fresh lemon juice is the absolute game-changer here. It brightens all the flavours, cuts through the earthiness of the lentils, and makes the whole soup taste vibrant and fresh. Do not skip the lemon!
Now, taste it. It will probably need more salt, and definitely some freshly ground black pepper. Lentils absorb a lot of seasoning, so be generous here until the flavours really come through.
⑤ Finish & Serve
You did it! Ladle that hot, steaming Easy 30-Minute Lentil Soup into bowls. Serve it immediately while it’s piping hot, and please, please have some thick slices of warm, crusty Bread on the side. It’s practically non-negotiable for dunking! A few extra lemon wedges and a sprinkle of fresh parsley on top make it look (and taste) even better.
My Top Tips & Variations for This Easy Lentil Soup
After making this soup dozens of times, I’ve picked up a few tricks. This recipe serves as a fantastic starting point, but it’s easy to customise.
Let’s Talk Lentils (Best Lentils for Quick Soup)
The recipe calls for green or brown lentils, and I recommend sticking with them for this specific soup. Why? They hold their shape beautifully, giving the soup a wonderful, hearty texture.
- Can I use red lentils? (A great Red Lentil Soup 30 Minutes option!) You absolutely can, but it will be a different soup. Red lentils break down completely when cooked, resulting in a much thicker, creamier, puree-style soup. It’s delicious, but it won’t have the same “chunky” texture. The good news? They cook even faster, probably in about 20 minutes!
What Spices Go Well with Lentil Soup?
This trio of cumin, coriander, and smoked paprika is my favourite, but you can certainly experiment.
- Toss in a bay leaf while the soup simmers.
- Add one teaspoon of dried oregano or thyme with the other spices.
- Want a little heat? A pinch of cayenne pepper or red pepper flakes will do the trick.
Make it Your Own (Substitutions & Add-ins)
This is a perfect “clean out the fridge” soup.
- Greens: No spinach? No problem. Chopped kale is fantastic. Just add it about 5 minutes before the lentils are done, as it’s tougher and needs more time to soften.
- Broth: I use vegetable broth to make this a vegan lentil soup, but if you’re not a vegetarian, chicken broth works just as well.
- Extra Veggies: Do you have a zucchini, bell pepper, or some potatoes? Chop them into small pieces and add them to the carrots and celery.
Storage & Make-Ahead Tips
This is one of my favourite meals to prep on a Sunday. It tastes even better the next day!
- To Store: Let the soup cool completely, then store it in an airtight container in the fridge for up to 5 days.
- To Freeze: This soup freezes beautifully! Ladle it into freezer-safe containers or zip-top bags (laid flat) and freeze for up to 3 months.
- To Reheat: The soup will thicken significantly in the fridge as the lentils absorb more liquid. When you reheat it on the stove or in the microwave, add a good splash of water or vegetable broth to thin it back out to your desired consistency.
What to Serve with Your Hearty Lentil Soup
While this is a satisfying meal all on its own, a little something on the side never hurts!
- Crusty Bread: I mentioned this, but it bears repeating. Sourdough, a baguette, or a hearty whole-grain loaf is essential for sopping up every last drop.
- A Zippy Salad: Because the soup is so earthy and warm, I love pairing it with a bright, acidic salad. Think simple arugula with a lemon-mustard vinaigrette.
- A Classic Grilled Cheese: For the ultimate comfort food pairing, serve a half-sandwich of a gooey, toasty grilled cheese. It’s a dream combo.
- A Dollop of Creaminess: A spoonful of plain Greek yoghurt (or sour cream) on top is delicious. To keep it vegan, a dollop of unsweetened coconut yoghurt or a cashew cream is fantastic.
Frequently Asked Questions (FAQ)
Do lentils need to be soaked before making soup?
Nope! And that’s one of the biggest reasons this is a quick lentil soup recipe. Green and brown lentils do not require any soaking. Just give them a quick rinse in a fine-mesh sieve to remove any dust and pick them over to check for any tiny pebbles (it’s rare, but it happens!).
How to make quick and easy lentil soup?
You’re looking at it! The secret is not to overcomplicate things. You need three main stages: 1) Sauté your aromatic veggies (onion, carrot, celery, garlic) to build a flavour base. 2) Add your liquids, lentils, and spices and simmer for 30 minutes. 3) Finish with acid (lemon juice!) and greens. It’s that simple.
What are the common mistakes in making lentil soup?
I see two big ones all the time. The first and most common mistake is under-seasoning. Lentils are earthy and require a substantial amount of salt, as well as crucially, acid (like our lemon juice) to taste bright and flavorful. Always taste and adjust your seasoning at the end! The second mistake is overcooking. If you simmer them for an hour, your green lentils will become tender and soft. Stick to that 30-minute window for the perfect balance of tenderness and integrity.
Can you boil lentils for 30 minutes?
Great question! You’ll bring the soup to a boil initially, but then you immediately reduce the heat to a gentle simmer for 30 minutes. A hard, rolling boil for the entire time would be too aggressive and could break down the lentils too much. A gentle, happy bubble is precisely what you’re looking for.
