Ingredients and Preparation

Main Ingredients

• 1 cup dry lentils (brown or green)
• 4 cups vegetable broth or water (for a heartier version, use chicken or beef broth)
• 1 medium onion, roughly chopped
• 2 Roma tomatoes, roughly chopped
• 2 garlic cloves, minced
• ⅓ cup diced carrot
• 1 teaspoon olive oil (or any neutral cooking oil)
• Salt, to taste
• ¼ teaspoon dried oregano
• 1 bay leaf
• Handful of fresh cilantro with stems (can be removed after cooking or left in)

Optional Additions

• 1 cup cooked, shredded chicken or browned ground beef for extra protein
• ½ teaspoon cumin for a warm, earthy flavor
• ½ teaspoon smoked paprika for a deeper, slightly smoky taste
• ½ cup diced zucchini or bell pepper for added vegetables

Ingredient Substitutions

• If fresh tomatoes are unavailable, use canned diced tomatoes (about ½ cup)
• If you don’t like cilantro, substitute with fresh parsley for a milder herb flavor
• Swap the olive oil for avocado oil or butter for a slightly richer taste

Step-by-Step Instructions

1. Prepare the Ingredients

Start by rinsing the lentils thoroughly under running water. This removes any dust or debris and helps them cook evenly. Set them aside.

Next, add the chopped tomatoes, onion, and minced garlic into a blender. Blend until smooth to create a flavorful puree that forms the base of the soup.

2. Sauté the Aromatics

If using an Instant Pot, press the “Sauté” button and allow it to heat up. Once hot, add the oil to the inner steel pot. If cooking on the stovetop, use a large pot over medium heat.

Carefully pour in the onion-tomato puree and stir for 1 to 3 minutes until fragrant. This step helps deepen the flavors and brings out the natural sweetness of the tomatoes and onions.

3. Add the Lentils and Vegetables

Once the puree is aromatic, add the rinsed lentils and diced carrots. If you are using additional vegetables like zucchini or bell peppers, add them at this stage. Stir everything together to ensure the lentils are coated with the flavorful puree.

4. Season and Add Liquid

Season the mixture with salt, dried oregano, and the bay leaf. If you enjoy more spice, you can add cumin or smoked paprika at this point. Pour in the broth or water, stirring well to combine.

5. Pressure Cook or Simmer

Instant Pot Method:

• Press “Cancel” to turn off the Sauté function.
• Secure the lid and set the Instant Pot to “Pressure Cook” for 10 minutes.
• Once done, do a quick release of pressure by turning the valve to venting.

Stovetop Method:

• Bring the soup to a boil, then reduce the heat to a low simmer.
• Cover and let cook for about 25-30 minutes, or until the lentils are tender.

6. Final Touches

Once the soup is cooked, remove the bay leaf and the bunch of cilantro (if desired). Stir well, taste, and adjust seasoning as needed.

If you’re adding shredded chicken or browned ground beef, stir it in at this stage and let it warm through for a few minutes before serving.

Beginner Tips and Notes

How to Know When Lentils Are Cooked

Lentils should be soft but not mushy. If they still have a firm bite, cook them for a few more minutes.

Troubleshooting Common Issues

• Soup too thick? Add more broth or water to reach your desired consistency.
• Too bland? Add an extra pinch of salt, a squeeze of fresh lime, or a dash of cumin for more depth.
• Overcooked lentils? Reduce the cooking time next time and check them sooner.

Kitchen Tips for Efficiency

• Chop the onion, garlic, and tomatoes ahead of time for faster prep.
• Rinse and sort lentils before cooking to remove any debris.
• Use an immersion blender at the end if you prefer a smoother soup.
