Ingredients for Lentil Soup

Ingredients

  • Vegetables: For the vegetables, youā€™ll need to prep 2 yellow onions, enough celery, and medium carrots to fill a cup each. The vegetables give the soup a richer flavor and add to the hearty texture. After cooking the veggies in oil, add salt and black pepper to season them.
  • Herbs: I also use dried thyme to season the veggies. You can feel free to mix in other dry herbs as desired.
  • Garlic: Add 6 cloves of garlic along with the veggies for a strong and fragrant taste.
  • Tomatoes: To add rich and tangy tomato flavor to the vegetable broth, use tomato paste and diced Roma tomatoes.
  • Green Lentils: Add lentils to the soup recipe when uncooked. The cooked lentils are tender and flavorful. Green lentils make the soup hearty and healthy with a distinct peppery flavor.

How to Make

Time needed:Ā 1 hour and 10 minutes.

Chefā€™s Note: Cooking Green Lentils

There are a couple reasons I use green lentils in this recipe versus red lentils, like I use in my lentil stew. Since Iā€™m using fresh tomatoes, I want the broth to simmer for at least 45 minutes to help break them down. Green lentils are more firm than other lentils so they will hold their shape better in the longer simmering time. A longer cooking time is needed for these lentils versus quicker cooking brown lentils, too. But the nice thing is once everything is in the pot, there isnā€™t any hands on time.

Can this be made ahead of time?

Lentil soup can be made beforehand, and it often tastes even better the next day as the flavors meld.

Cooking Recipe Tips & Tricks

  • Donā€™t Overcook the Lentils: Watch the cooking time. Lentils should be tender but still hold their shape. Different types of lentils have varying cooking times.
  • Taste as You Go: Always taste the soup before serving. Adjust the seasoning with salt, pepper, or acidity (like lemon juice) to enhance the flavors.
  • Garnish for Presentation: Top your soup with fresh herbs, a dollop of yogurt, or a drizzle of olive oil for a beautiful finish.

Ideas to Serve

You can serve this soup topped with some fresh herbs and crusty bread for an easy meat-free dinner. I like serving it with fresh baked Italian bread or an extra buttery Garlic Bread. Turn this rustic soup into an elegant meal, perfect for a special luncheon, by pairing it with a nice salad like my Beet Salad or Winter Pear Salad.

How to Store

  • Serve: After cooking, donā€™t leave Lentil Soup out at room temperature for more than 2 hours.
  • Store: To keep leftovers, let the soup cool. Then transfer it to an airtight container to put in the fridge for up to 5 days.
  • Freeze: You can also put the soup in a freezer-safe container to keep frozen for 4-5 months.

Frequent Questions

Should I blend Lentil Soup?

Whether or not you blend the Lentil Soup is up to your own preference. I prefer to leave the lentils whole to add extra texture, and the tomato paste makes the broth pretty thick without blending. However, some people prefer to blend their lentil soup part or all of the way to thicken the recipe. Iā€™d recommend using an immersion blender if you have one. Then blend to your preferred consistency.

How do you make Lentil Soup in a slow cooker?

To make Lentil Soup in the slow cooker, saute the vegetables on the stovetop. Then add the veggies, tomatoes, broth, and lentils to the slow cooker. Cover the slow cooker, and turn to low heat for 7-8 hours of cooking time.

Variations

  • Chicken Lentil Soup: This recipe is both vegetarian and vegan friendly. However, if youā€™d like to add some meat, you can mix leftover Shredded Chicken into the soup and use chicken broth in place of veggie broth.
  • Lentil Colors: Iā€™ve made this recipe with green lentils. However, if you want a different color of lentils, you can use red or brown lentils. I would suggest using whole lentils so they donā€™t overcook.
  • Pasta: Mixing pasta into your veggie soup is an easy addition to make. Cook egg noodles separately. Then add the noodles during the last few minutes of cooking.
  • Vegetables: There are lots of fresh veggies that you could add to your soup. Try mixing in cubed potatoes or sweet potatoes in the beginning so they cook all the way. Add kale, fire-roasted tomatoes, or canned corn in the last 20 minutes.
  • Flavor Additions: To add an extra layer of flavor, you can mix in spices or fresh herbs like red pepper flakes, lemon pepper, cumin, or rosemary. You could also add a bit of heat by mixing in a dash of hot sauce. Or, add some lemony flavor with a squeeze of lemon juice.
