- Carrots – Adds color, texture, and a touch of earthy sweetness to the soup.
- Celery – Adds a bit of texture to your soup.
- Vegetable broth – Feel free to use your own broth or store-bought. Using bouillon cubes? Be sure to taste the broth and adjust the salt you add to the recipe.

- Parsley – This bright green, refreshing herb makes a perfect topping for the finished soup.
How to Make Instant Pot Lentil Soup
- Saute. You’ll want to use this function to soften the vegetables and add flavor to the soup.
- Seal and Cook. Close the lid and make sure the valve is in sealing mode. Select MANUAL (high pressure) and set the cooking time to 15 minutes.
- Natural Release. When the cooking time is complete, wait another 15 minutes to allow the pressure to release naturally.
- Serve. Open the lid carefully. Stir and serve hot with fresh parsley.
Serving Suggestions
Prefer a creamier soup? Add milk or heavy cream to the soup just before serving. For a creamier soup with a little tang, serve it with a dollop of sour cream or plain Greek yogurt.
Lentil soup goes hand in hand with a side of your favorite crackers or my Easy Garlic Bread. Or you can take it a step further with my Cheesy Garlic Bread or flaky Puff Pastry Breadsticks.

- 1 can diced tomatoes 28 ounce
- 8 cups vegetable broth
- 1 teaspoon kosher salt

- When cook time ends, allow pressure to release naturally, this will take about 15 minutes. Open the lid carefully and stir the soup.
- Serve hot with fresh parsely.
Notes
- We love using green lentils because they hold their shape during pressure cooking and have a nice, firm texture.
- Serve with a dollop of sour cream or plain Greek yogurt. Serve soup with a side of bread or crackers. Want something a bit heartier? Add chicken breasts or sausage to the soup.
- Store soup in refrigerator for up to 4 days for best flavor and texture.
- Freeze leftover soup for up to 3 months in freezer safe, air tight container. Thaw in refrigerator before reheating.
- Want to spice it up? Add red pepper flakes while sauteeing the vegetables, or when serving.
- Prefer a creamier soup? Add milk or heavy cream when serving.
- When reheating leftovers, the soup may have thickened. Add in extra vegetable broth before reheating to thin the soup to desired consistency.
