Step-By-Step Recipe: Making Red Lentil Soup
This easy red lentil soup follows a simple process, requiring only fundamental chopping, sautéing, and simmering skills. Here’s a detailed, approachable guide:
- Prepare your veggies. Dice onion, carrots, and celery finely for even cooking. Mince the garlic.
- Sauté the aromatics. Warm olive oil or butter in a large pot over medium heat. Add onion, carrot, and celery, and cook until softened (about 5 minutes), stirring occasionally. Add garlic and cook for 1 minute more.
- Add the spices and tomato paste. Stir in cumin, smoked paprika (or sweet), and tomato paste. Let cook for 30–60 seconds, allowing the spices to bloom and the tomato paste to caramelize a little.
- Combine lentils and broth. Add rinsed red lentils to the pot, stirring to coat with the aromatic mixture. Pour in broth, scraping up any flavorful bits from the bottom of the pot.
- Simmer. Bring to a gentle boil. Reduce heat to low, partially cover with a lid, and simmer for 15–20 minutes, until lentils are fully tender and starting to break down. Skim off any foam if needed.
- Adjust seasoning and blend (optional). Taste and add salt and pepper. For a smooth, silky soup, use a stick blender or stand blender to puree part or all of the soup, or leave it chunky for added texture.
- Brighten and serve. Stir in lemon juice, taste again, and adjust salt, pepper, or more lemon if desired. Serve hot.
This process delivers a deeply flavorful, nourishing bowl of soup with minimal fuss.
Cooking Tips for Best Results
- Always rinse red lentils to remove dust and improve texture in the final soup.
- Sautéeing spices and tomato paste unlocks essential flavor, so don’t rush this step.
- For ultra-creamy soup, blend thoroughly; for rustic texture, just mash lightly after cooking.
- Lemon juice and final seasoning at the end can make or break the vibrancy, so taste before serving.
- Add chopped greens in the last 3–4 minutes for extra nutrition.

Frequently Asked Questions (FAQs)
Q: Can I use brown or green lentils instead of red?
A: While you can substitute brown or green lentils, they take longer to cook and won’t break down as smoothly, resulting in a chunkier, earthier soup and a different color.

A: No soaking is necessary for split red lentils. Simply rinse thoroughly before cooking.
