Instructions to Make Hearty Vegan Lentil Soup

Making Hearty Vegan Lentil Soup is as easy as it is comforting. This step-by-step guide walks you through every part of the process—whether you’re a seasoned cook or just learning to sauté an onion without setting off the smoke alarm. Follow these clear instructions and you’ll have a delicious, nourishing soup ready in under an hour. Bonus: only one pot to clean!

Step 1: Gather and Prep Your Ingredients

Before you turn on the stove, take a moment to chop your veggies and rinse your lentils. Dice the onion, carrots, celery, green beans, potatoes, and tomatoes. If you’re using fresh herbs or leafy greens like kale or spinach, give them a good wash and rough chop. This kind of prep work (also known as mise en place) keeps things stress-free once the heat is on. If you’re short on time, check out our preparation tips for using frozen vegetables or pre-chopped grocery store shortcuts.

Pro Tip: Soak lentils for 10–15 minutes if you want to slightly reduce cooking time, although it’s not necessary for this soup.

Step 2: Sauté the Aromatics

In a large pot or Dutch oven, heat 1/4 cup of water (or olive oil if you’re feeling indulgent) over medium heat. Add the diced onion, carrots, celery, and minced garlic. Stir frequently and cook for about 5 minutes, until the veggies begin to soften and smell amazing.

This is your flavor base—think of it as the foundation of your soup’s personality. Once the vegetables have cooked down a bit, stir in the spices: 1½ teaspoons of paprika, ½ teaspoon of cumin, and ½ teaspoon of curry powder. Let them toast for another minute to really wake up their flavors.

Step 3: Add the Veggies, Lentils, and Liquid

Now it’s time to bring in the heavy hitters. Add the green beans, diced tomatoes (with juices), baby potatoes, and rinsed lentils. Pour in 6 cups of water or low-sodium broth—vegetable broth adds an extra depth of flavor, especially if you’re skipping the oil.

Give everything a good stir so the lentils don’t stick to the bottom. Crank the heat to high and bring the pot to a gentle boil. Once bubbling, lower the heat to a simmer, partially cover the pot (leave the lid slightly ajar), and cook for about 30–35 minutes.

Keep an eye on the pot and stir occasionally to prevent sticking. This is when the soup starts to come together—your kitchen will start to smell incredible. If you’re a slow cooker lover, you might enjoy our slow cooker beef and barley soup for another cozy, low-effort dinner option.

Step 4: Stir in the Greens

With about 5 minutes of simmering left, gently stir in your leafy greens. Baby spinach wilts quickly, while kale might need a couple extra minutes. Greens not only add color but also boost the nutrition factor (hello, fiber and iron!).

If the soup thickens too much, add up to 1 more cup of water or broth to reach your desired consistency. Soup should be hearty, but not stew-thick.

Step 5: Brighten with Lemon and Season to Taste

Once the lentils and veggies are perfectly tender, finish with the juice of one lemon. This single step adds a pop of brightness that makes every bite feel fresh and balanced.

Season with salt and pepper to taste, and don’t be shy with the fresh parsley—it adds both flavor and visual appeal. Give the pot one final stir and take a taste. Adjust as needed: more salt, more lemon, a dash of spice—this is your moment to fine-tune.

Step 6: Serve and Savor

Ladle the soup into bowls and serve it hot. For extra cozy points, pair it with crusty bread, vegan naan, or even a scoop of cooked rice for a heartier meal.

Top with more parsley or a swirl of olive oil if you’re feeling fancy. This soup is perfect for make-ahead lunches, freezer meals, or feeding a hungry crowd.

Key Tips for Making Hearty Vegan Lentil Soup

• Use green or brown lentils—red lentils get too mushy here.
• Chop veggies evenly so everything cooks at the same pace.
• Don’t skip the lemon juice at the end—it brightens the whole dish.
• Add more broth if it thickens up too much during simmering.
• Customize with spices like thyme or Italian seasoning if you want a different vibe.
• Make it freezer-friendly by cooling completely before storing in airtight containers.
• Cooking for kids? Sub the greens with something milder like baby spinach and let them sprinkle their own toppings—it makes them way more excited to eat it.

Storage and Reheating Tips for Hearty Vegan Lentil Soup

Leftovers? Lucky you! This hearty vegan lentil soup keeps like a champ. Store cooled soup in an airtight container in the fridge for up to 5 days. When you’re ready to reheat, just pop it on the stove over medium heat or microwave in short bursts, stirring in between. Add a splash of water or broth if it’s gotten a bit too thick. Freezing? No problem. Portion it into freezer-safe containers and stash it for up to 3 months. Thaw overnight in the fridge or reheat straight from frozen (just give it a little extra time). Pro tip: Freeze in single servings for grab-and-go lunch magic!
