Ingredients

  • 1 yellow onion
  • 2 stalks celery
  • 1 large carrot (or 2 small)
  • 5 oz. mushrooms
  • 8 oz. white potato (about 1 medium)
  • 4 cloves garlic
  • 15 oz. can diced tomatoes (or fire-roasted)
  • 6 cups vegetable broth
  • 1 cup green/brown lentils (uncooked)
  • 1 1/2 tsp. Italian seasoning
  • 1-2 cups fresh baby spinach (optional)

Instructions

  • Dice onion, carrot, and celery. Dice mushrooms and potato. Set aside.
  • In a stockpot over medium-high heat, add onion, carrot, and celery. Sauté for about 7-8 minutes. (I use 3 Tbsp. water/veggie broth for no-oil sauté method, adding more as needed.)
  • Meanwhile, mince garlic.
  • When onion is translucent, add garlic, mushrooms, potato, and Italian seasoning. Stir and sauté for 2-3 minutes.
  • Add diced tomatoes, vegetable broth, and lentils (rinsed and drained). Increase heat and bring to a light boil.
  • Then reduce heat, cover, and lightly simmer for 25-30 minutes or until lentils are tender.
  • Roughly chop spinach and stir in during the last couple minutes of cooking. Salt and pepper to taste.

Notes

*Thickness: I enjoy dense soup but if you prefer yours thinner, reduce lentils to about 3/4 cup.
Vegetables: Change it up with green beans, broccoli, kale, corn, peas, cauliflower, cabbage, zucchini, etc.
Garnish: Add fresh parsley, cilantro, basil, or red pepper flakes before serving if desired.
