- Add more greens like kale or Swiss chard instead of spinach.
- Make it spicy with red pepper flakes or a pinch of cayenne.
- Want more protein? Toss in a can of chickpeas or diced tofu.
- Prefer it smoother? Blend half the soup for a creamier texture.
What to Prep Ahead? (So You’re Not Rushing Later)
Let’s be honest, nobody wants to be frantically chopping veggies at 6 p.m. That’s why I love prepping a few things ahead of time. You can knock these out the night before or even on your meal prep day.
Here’s what you can do ahead of time:
- Dice the onion, carrots, and celery – Store in an airtight container in the fridge for up to 2 days.
- Rinse and sort the lentils – Keep them in a covered bowl or container until ready to use.
- Measure out the spices – Mix them together in a small jar for quick dump-and-stir action.
- Mince the garlic – Store in a little olive oil in the fridge (just use within 2–3 days).
- Wash and chop the spinach – Store in a paper towel-lined container to keep it fresh.

kcalA hearty and healthy one-pot lentil soup packed with vegetables, warming spices, and a burst of lemon for a cozy and satisfying meal.
Ingredients
2 tablespoons olive oil
1 large onion, diced
3 carrots, diced
3 celery stalks, diced
3 cloves garlic, minced
1.5 cups dried lentils, rinsed
1 can (14.5 oz) diced tomatoes
6 cups vegetable broth
1 teaspoon cumin
0.5 teaspoon smoked paprika
0.5 teaspoon dried thyme
2 bay leaves
Salt and pepper to taste
2 cups chopped fresh spinach (optional)
Juice of 1 lemon
Directions
- First, you’ll heat some olive oil in a big pot—this is your flavor base. Toss in your onion, carrots, and celery and let them soften until they start smelling amazing (you’ll know when!). Then add the garlic, just for a minute so it doesn’t burn.
- Next, in go the lentils, diced tomatoes, broth, and all those gorgeous spices—cumin, smoked paprika, thyme, and a couple of bay leaves. Bring it to a boil, then drop the heat, cover, and let the magic happen. About 30–35 minutes later, your lentils should be perfectly tender.
- To finish it off, stir in some fresh spinach (if you’re using it) and let it wilt right into the soup. A squeeze of lemon juice at the end brightens the whole dish. Taste and adjust salt and pepper as needed.
Notes
- Use brown or green lentils, they hold their shape well and don’t get mushy.
- Make it thicker by blending 1/3 of the soup with an immersion blender.
- Add grains like cooked quinoa or rice for an extra boost.
- Fresh herbs like parsley or cilantro make a great garnish.
- Lemon juice at the end is non-negotiable, it adds brightness and balances the earthy flavors.

Secrets to the Best Lentil Soup Ever
Okay, real talk—this lentil soup is already a winner, but if you want to take it from “great” to “can’t-stop-eating-it,” I’ve got you covered. These are the little chef-y moves that make a big difference. Trust me, I’ve made this soup more times than I can count, and these tips never fail.
- Sauté your aromatics thoroughly – Take your time with the onion, carrots, and celery. That golden color means flavor!
- Toast the spices – Let the cumin and paprika hit the heat briefly before adding the broth for deeper, richer flavor.
- Use a good-quality vegetable broth – It’s the backbone of the soup, so make it count. Homemade or low-sodium is best.
- Don’t skip the lemon juice – It wakes up the flavors and cuts through the earthiness of the lentils.
- Let it rest before serving – Giving the soup 5–10 minutes off the heat helps the flavors mingle beautifully.
- Double it up – It freezes like a dream and makes for easy future lunches.
- Pair with a cozy companion recipe – For a seriously comforting combo, serve this soup alongside a cheesy sandwich or one of these Cheesy Garlic Chicken Wraps for a satisfying twist.
Lentil Soup, Your Way – Tasty Variations to Try
Feel like switching things up? This soup is super versatile and plays well with different flavors and dietary needs. Here are some delicious ways to make it your own:
- Spicy Lentil Soup
Add ½ teaspoon of red pepper flakes or a pinch of cayenne with the spices. It brings a lovely heat that lingers just enough. If you’re into bold flavors, you might also enjoy this spicy twist on a classic: White Chicken Chili. - Curried Lentil Soup
Swap the cumin and paprika for 1 tablespoon of curry powder and a dash of turmeric. It turns the soup into a warm, fragrant bowl of goodness. - Lentil and Coconut Soup
Add 1 cup of coconut milk toward the end of cooking for a creamy, slightly sweet twist. It pairs beautifully with lemon or lime. - Lentil and Sweet Potato Soup
Dice one medium sweet potato and add it in with the lentils. It adds a touch of sweetness and makes the soup extra hearty. If you’re a fan of hearty, one-pot meals, this variation gives a similar cozy vibe to this Lasagna Soup that’s always a hit. - Blended Lentil Soup
Use an immersion blender to puree half (or all) of the soup for a creamier, velvety texture. Great if you’re into thicker soups. - Lentil Soup with Sausage (non-vegetarian)
Brown sliced chicken or turkey sausage with the veggies for a protein boost and smoky, savory bite. You can even slow-cook this variation similar to how you’d prepare a Crockpot White Chicken Chili, just toss it all in and let the flavors meld all day long.
FAQs: Your Lentil Soup Questions, Answered
For a hearty, textured soup, green or brown lentils are the way to go. They hold their shape well and don’t turn mushy. Red lentils cook faster and create a creamier texture, which is great if you prefer a blended or smoother version of the soup.
Nope! That’s the beauty of lentils. Unlike beans, lentils don’t require soaking. Just give them a quick rinse to remove any debris, and you’re good to go. Skipping the soak makes this soup even quicker to throw together.
Absolutely. Lentil soup freezes like a dream. Let it cool completely, transfer it to freezer-safe containers or zip-top bags, and freeze for up to 3 months. Thaw overnight in the fridge and reheat gently on the stove or in the microwave.
Lentils need plenty of seasoning to shine. Don’t skimp on spices, herbs, or salt. Adding a squeeze of lemon at the end really enhances the flavor, too. For an extra boost, try stirring in a spoonful of pesto, harissa, or grated Parmesan (if not vegan).
You’ve got a few easy options:
– Simmer the soup uncovered for a bit longer to reduce the liquid.
– Mash a few ladles of the soup with a potato masher and stir it back in.
– Use an immersion blender to puree a portion of the soup while keeping the rest chunky.
Yes! Lentil soup is naturally high in fiber and protein, which can help keep you full longer. It’s also low in fat and calorie-dense, making it a smart, satisfying meal choice for weight-conscious eaters.
Grab a Bowl and Get Cozy
There’s something undeniably comforting about a big, steamy bowl of lentil soup. It’s humble, hearty, and nourishing in all the best ways. Whether you’re meal-prepping for the week, feeding a hungry family, or just need something warm and grounding, this lentil soup is here for you.
Give it a try, and don’t be afraid to put your own spin on it. Once you make it, it might just become a staple in your kitchen like it is in mine. And hey, if you do, be sure to grab some crusty bread and maybe even a blanket—because cozy season is officially on.
