How to Make Spicy Lentil Soup

Step-by-Step Cooking Instructions

1. Heat olive oil in a large pot over medium heat. Add chopped onion and carrot. Cook 5–7 minutes until soft.
2. Add garlic, cumin, smoked paprika, and chili flakes. Cook 1 minute until fragrant.
3. Stir in rinsed lentils and crushed tomatoes. Mix well.
4. Pour in broth and bring to a boil. Lower heat, cover, and simmer 20–25 minutes for red lentils (30–35 minutes for brown) until lentils are soft.
5. Use a spoon or hand blender to mash a few lentils for creaminess, if you like.
6. Stir in lemon juice, salt, and pepper. Taste and adjust seasoning.

Tips for Texture, Timing & Tools

• Rinse lentils well to remove dust and reduce foaming.
• Red lentils break down faster and make a smoother soup; brown keep their shape more.
• A hand blender helps make the soup creamy. If you do not have one, mash gently with a spoon.
• If the soup is too thick, add a bit more broth or water. If too thin, simmer uncovered to reduce.

Storage & Reheating

How to Store It Right

Cool the soup to room temperature, then store in airtight containers in the fridge for up to 4 days. For longer storage, freeze in meal-size portions for up to 3 months.

Reheating Without Losing Flavor

Thaw frozen soup in the fridge overnight or reheat from frozen on low heat, stirring often. Add a splash of broth or water if it thickens too much. Freshen the flavor with a squeeze of lemon and a pinch of salt when reheating.

A Dish Worth Making Again and Again

This soup is easy to scale. Make a double batch and freeze portions for busy nights. Small changes to spice levels or added veggies keep it new and interesting each time.

FAQs

Can I use brown lentils instead of red lentils?

Yes. Brown lentils hold their shape and need a bit longer to cook (about 30–35 minutes). Red lentils cook faster and make a creamier soup.

How can I make the soup less spicy for kids?

Reduce or omit the chili flakes and use mild paprika instead of smoked paprika. You can always add heat later to individual bowls.

Can I freeze this soup?

Yes. Cool fully, portion into airtight containers, and freeze up to 3 months. Thaw overnight in the fridge before reheating.

Is this soup high in protein?

Lentils are a good plant protein source. One serving will give you a solid amount of protein plus fiber and iron.
