Shawn described this lentil soup as a surprising instance where something healthy actually tastes delicious too. So, that just about sums up my work here today. Marly out!

You may be wondering, is lentil soup vegan? Even well-meaning home cooks may THINK they’re making vegan or vegetarian lentil soup but may include things like chicken broth or beef broth. It’s always good to ask about ingredients.

Of course, when you make it yourself, there’s no guess-work involved!

What You Need

You can find the full printable recipe, including ingredient quantities, below. But first, here are some explanations of ingredients and steps to help you make this recipe perfect every time.

Here’s the ingredients you’ll need:

  • Aromatics — We’ll cook onion and garlic in some olive oil
  • Vegetables — Carrots and potatoes (I used red potatoes) are favorite veggies
  • Vegetable broth — I prefer to use Better than Bouillon Vegetarian here
  • Stewed Tomatoes — You’ll need a 14.5 ounce can of stewed tomatoes
  • Tomato paste — A bit of tomato paste adds thickness and tomato flavor
  • Tamari — This is a gluten-free soy sauce, or you can substitute soy sauce
  • Spices — For this soup, curry powder and ground turmeric are best. You could add a 1/2 teaspoon of ground cumin to give it a chili flavor.
  • Lentils — I prefer simple brown lentils because they’re affordable and accessible and cook up perfectly.
  • Cooked Brown Rice — You can cook brown rice yourself or buy pre-cooked packaged brown rice
  • Spinach — I add a 10-ounce package of frozen spinach, or you can use 2–3 cups of fresh spinach. Make lentil kale soup by adding chopped kale.
  • Salt and Pepper — After the soup is done, add salt and pepper to taste.

Marly’s Tips

I always keep a few 10-ounce packages of frozen spinach in my freezer. That’s because freezing veggies doesn’t impact the nutritional value. In fact, some studies have shown that frozen is better because it’s frozen at the peak of ripeness.

How to Make Lentil Soup

I find most vegan recipes way easier than cooking with meat! Why? Because to make this lentil soup, there’s no pre-cooking any meat! That means no worrying about raw meat on your counters and all the washing involved with that either.

Here’s how to make this easy lentil soup:

  1. Cook Aromatics — Heat oil in a pot and sauté onion over medium heat until onion is tender. Add the chopped garlic and cook for about a minute.
  2. Vegetables — Add the chopped carrots and potatoes and cook them until tender.
  3. Broth & Lentils — Add water, broth, tomatoes, tomato paste, tamari (or soy sauce), and spices. Stir this all together. Add the dried lentils and bring it to a boil. Then reduce the heat and place the lid ajar on the pot. See more on cooking lentils below. Cook until the lentils are tender, about 35 minutes. 
  4. Rice and Spinach — Once the lentils are tender, stir in cooked brown rice, and spinach. Cook until the spinach is heated through and then remove it from heat. Allow the soup to cool for 10–15 minutes.
  5. Serving — To serve, place individual servings in a bowl and cook in a microwave until heated through. Garnish with chopped green onions, tomatoes, and/or coconut yogurt.

Storage Tips

Transfer cooled soup to sealable containers. This will keep in the fridge for up to 7 days or in the freezer for up to 2 months.

How to Cook Lentils in Soup

Lentils, a legume, are one of the world’s best ingredients for a vegetarian or a vegan diet because they’re cheap and easy to make. They don’t even need pre-soaking before cooking!

To me, the best lentil soup recipes use brown lentils. That’s because it’s easier to find them and they have an intact texture. In fact, you can find brown lentils in most grocery stores. You can substitute green lentils, black lentils, or red lentils, but be aware the cooking time is different for these.

The trick to cooking lentils is to bring the liquid to a boil, then reduce the heat until the water is at a low simmer. The water should be moving, but not too much. This post on cooking lentils from The Kitchn is really good.

If you simmer too high, you’ll lose the liquid too quickly and some of the lentils might be mushy. However, if you simmer too low, the lentils will still be underdone.

Meal Planning

This spicy curry lentil soup is great for meal planning because you can make a big batch on the weekend and enjoy it for lunch and/or dinner the rest of the week. In fact, the flavors in this best ever soup intensify over time, making it the ultimate in meal prepping recipes.

Mediterranean Lentil Soup

Are you following a Mediterranean diet? It includes meals inspired by peoples living in Greece, Southern Italy, and Spain. A lot of science supports this mostly plant-based diet for longevity and health.

You could group this in the meatless Mediterranean Lentil Soups category because it fits perfectly in that meal plan. I know the curry changes the profile a bit, but it offers nutrients and flavor. In addition to providing fiber and other nutrients, this lentils recipe provide a lot of plant-based protein!

Can Lentil Soup Be Frozen?

You can freeze spiced lentil soup for up to 2 months. Simply allow the soup to cool and then transfer to freezer-safe containers, label, and freeze. To serve frozen soup, remove it from the freezer and place it in the microwave, and cook in defrost mode until the soup is thawed. Continue cooking until heated through.
