Servings6 medium bowls


  • 1 yellow onion
  • 3-4 cloves garlic
  • 2 medium carrots
  • 6 oz. mushrooms (I use cremini)
  • 1 zucchini
  • 15 oz. can diced tomatoes (or fire-roasted)
  • 4 cups vegetable broth*
  • 1 cup green/brown lentils (uncooked)
  • 1 1/2 tsp. dried basil (or other herbs of choice)
  • 1 cup fresh baby spinach


  • Dice onion.
  • In a stockpot over medium-high heat, add onion. Sauté for about 8 minutes. (I use 3 Tbsp. water/veggie broth for no-oil sauté method, adding more as needed.)
  • Meanwhile, mince garlic. Dice zucchini and carrot. Slice mushrooms.
  • When onion is translucent, add garlic, zucchini, carrots, mushrooms, and dried basil. Stir and sauté for 2 minutes.
  • Add diced tomatoes with juice and vegetable broth*.
  • Increase heat and bring to a light boil.
  • Rinse and drain lentils. Add lentils to pot and stir.
  • Reduce heat, cover, and lightly simmer for 25-30 minutes or until lentils are tender. (Add more broth or water if desired.)
  • Roughly chop spinach and stir in during the last couple minutes of cooking. Salt to taste. (Serve with fresh chopped parsley, basil, or cilantro if desired.)


*Thickness: I enjoy dense soup, but if you prefer yours thinner, simply add 2 additional cups vegetable broth or reduce the lentils to 2/3 cup.
Vegetables: Customize this with green beans, broccoli, kale, corn, peas, celery, cauliflower, cabbage, potato, etc.
Herbs: Change up the flavor with cumin, smoked paprika, Italian seasoning, thyme, oregano, etc.
Garnish: Add fresh parsley, cilantro, or basil before serving if desired.
