Rustic Lentil Potato Soup (Easy!)

Oct 18, 2015 by Kaitlin · 24 Comments

Jump to Recipe

This rustic Lentil Potato Soup recipe is only 10 simple ingredients and so easy to make! The rich, savory flavors remind me of a plant-based version of classic beef stew. (Vegan, gluten-free, oil-free.)

I'm tempted to dazzle you with a bunch of cool lentil facts, but I'll refrain. Let's keep it short and sweet: lentils rock.

They're easy to cook and filled with nutrients, protein, and fiber. Plus they're satisfying and budget-friendly.

This soup has so much hearty texture with chunks of potato, carrot, and mushroom. (It reminds me of a veganized version of classic beef stew!) Best of all, it's great for meal prep because I find the flavors only get better with time.

Plus it's easy to customize just the way you like it! See below for some ideas to get you started.

Ingredients for Lentil Potato Soup

For this recipe, you'll simmer in a large pot on the stove:

  • Yellow onion: Or you can use sweet onion or white onion instead.
  • Carrot
  • Mushrooms: I like cremini, but use your own favorite. Portobello, white button, shiitake, etc. (Or if you don't care for mushrooms, just substitute more potato instead!)
  • Potato: Either white, russet, or Yukon gold potato works great. I use 8 ounces or about one medium potato.
  • Garlic cloves: I like the taste of fresh, but you can substitute dried garlic powder if needed.
  • Vegetable broth: Be sure to use low sodium broth if desired.
  • Green lentils or brown lentils: The earthly flavor of green/brown lentils is really tasty in this recipe. But you could substitute red lentils or black lentils as well. (Just be aware red lentils have a sweeter flavor and don't hold their shape very well after cooking, so it will be more of a stew-like consistency.)
  • Fresh spinach: Or you can stir in fresh kale or swiss chard.
  • Tamari: Or substitute soy sauce, but I use tamari for gluten-free.
  • Italian seasoning: Or substitute other spices and herbs to taste.

Customizing

Herbs & seasonings: Change up the flavors as you see fit! Try dried oregano, dried basil, ground cumin, smoked paprika, coriander, parsley, thyme, bay leaves (remove before serving), turmeric, ginger, black pepper, or curry powder. A pinch of red pepper flakes or cayenne pepper can be added for some heat as well.

Veggies: Add other vegetables such as celery, sweet potatoes, bell pepper, broccoli, peas, tomatoes, or zucchini. Or stir in a tablespoon of tomato paste for richer flavor.

Serving

Garnish your bowl with fresh parsley or other herbs if desired. Or to brighten the flavors, try a squeeze of fresh lemon juice before serving. You can also stir in 1-2 teaspoons of balsamic vinegar or apple cider vinegar to the soup pot at the end of cook time.

Storing

Store leftovers in an airtight container in the refrigerator. I find they keep for about 5-6 days. Simply reheat in the microwave when ready to enjoy. The leftovers are especially delicious because the broth becomes even richer and more flavorful the next day!

Prep Time: 30 minutes minutes
Cook Time: 30 minutes minutes
Total Time: 1 hour hour
Author: Kaitlin - The Garden Grazer
Course: Soup
Cuisine: Gluten-Free, Oil-Free, Vegan
Servings: 5 medium bowls

Ingredients

  • 1 yellow onion
  • 1 large carrot
  • 8 oz. potato
  • 8 oz. cremini mushrooms
  • 4 cloves garlic
  • 2 tsp. Italian seasoning
  • 6 cups vegetable broth
  • 1 cup green/brown lentils
  • 1 cup fresh baby spinach
  • 2 Tbsp. tamari (or soy sauce)

Instructions

  • Prepare the vegetables: Dice the onion, carrot, and potato. Slice the mushrooms. Mince garlic.
  • In a stockpot over medium-high heat, sauté onion for 5 minutes. (I use 3 Tbsp. water/broth for no-oil-sauté method, adding more as needed.)
  • Then add the carrot, potato, and mushroom to the pot. Stir and sauté 3-4 more minutes.
  • Add the garlic and Italian seasoning. Stir and sauté 1 minute.
  • Add 6 cups broth. Increase heat and bring to a light boil.
  • Once boiling, add lentils (rinsed & drained). Cover and reduce heat to a simmer. Simmer for 30 minutes or until your lentils are tender.
  • Stir in tamari and spinach (roughly chopped) during the last couple minutes of cook time. Add salt & pepper to taste if desired.

Notes

Potato: 8 ounces equals about 1 medium potato. Either white, russet, or Yukon gold works great.
Mushroom-free: If you're not a fan of mushrooms, just substitute with another potato instead.
Variations: Swap in other herbs (or fresh herbs), tomato paste, celery, zucchini, bell pepper, or anything else that sounds good.
For gluten-free: Use tamari.

    It was a drizzly day here today, so that called for soup! This is absolutely delicious!! The flavour really was reminiscent of a comforting hearty stew. I found that the green lentils took about 45 minutes to soften up, but the extra time just enhanced the flavour that much more. I added a small squirt of vegan Worcestershire sauce just before adding the spinach. Such a perfect soup for this rainy day! Thanks for sharing another awesome recipe!

    Absolutely the best lentil soup I have made yet. So tasty. Did exactly as the recipe called except adding spinach. At the end added one more cup of water as I wanted it a little more soupy. Not sure why it took so long for the lentils to get soft. But that’s ok, these was the tastiest I have had. Love it!

    This looks delicious! I'm wondering if you've ever made this in a crock pot and if so, how did you do it?

      Hi Lindsay! I've never done this in the crock pot, but I'm guessing it'd do pretty well! My estimate is to toss everything in, and cook on high for about 5 hours. Would love to hear if you give it a go!

      I just tried this in the crock pot! Amazing! However, I'd say it only takes about 3.5-4 hours on high to cook!
