About the Recipe

This creamy red lentil soup is one of those recipes you make once and immediately add to your permanent rotation. Red lentils break down into a naturally velvety base without any cream, while carrots add subtle sweetness and kale brings color, fiber, and nutrients.

The magic happens when you caramelize the tomato paste with cumin and chili—a simple step that creates deep, warming flavor you’d never expect from such humble ingredients.

It’s nourishing, satisfying, gut-friendly, and surprisingly energizing. Perfect with warm sourdough, ideal for weekly meal prep, and ready in under 40 minutes.

 

Why this Soup Works

This healthy red lentil soup delivers comfort and nourishment in every spoonful:

 

Rich in plant protein + fiber — Red lentils offer a natural plant-protein boost and pair with kale and carrots to support steady energy, healthy digestion, and blood sugar balance.

Naturally anti-inflammatory — Caramelized tomato paste, cumin, garlic, and onions provide antioxidants that support overall wellness.

Packed with vitamins + minerals — Iron, folate, potassium, magnesium, vitamins A and C… all essential for energy production and metabolic health.

Satisfying without being heavy — The fiber-rich lentils and hydrating broth help keep you full longer while still feeling light and comforting.

 

So Easy to Make

Ingredients:

Olive oil
Onion, chopped
Garlic, minced
Tomato paste
Ground cumin
Chili powder or cayenne
Salt and pepper
Chicken or vegetable broth
Red lentils
Carrot, diced
Kale, chopped
Lemon juice
Fresh cilantro
Extra virgin olive oil (for serving)
Chili flakes (optional)
Feta cheese (optional)

Instructions:

Sauté aromatics
In a large pot, heat 3 tablespoons of olive oil over high until hot and shimmering. Add onion and garlic, and sauté until golden, about 4 minutes.

Caramelize tomato paste
Stir in tomato paste, cumin, ¼ teaspoon each salt and black pepper, and the chili powder. Cook for about 2 minutes, letting the tomato paste caramelize until it darkens slightly — this adds deep umami flavor.

Simmer the soup
Add broth, 2 cups water, lentils, and carrot. Bring to a simmer, then partly cover the pot and reduce heat to medium-low. Simmer until the lentils are soft, about 30 minutes. Taste and add more salt if needed.

Blend for texture
Using an immersion or regular blender, purée about half the soup, then return it to the pot. The soup should be somewhat chunky.

Add greens
In the last 5 minutes of cooking, stir in a generous amount of chopped kale and simmer until wilted and tender.

Finish and serve
Reheat, if necessary, then stir in lemon juice and cilantro. Serve warm, drizzled with extra virgin olive oil, and top with a squeeze more lemon and a sprinkle of chili flakes at the table for a bright, energizing finish.

 

Storage & Meal Prep

This soup actually tastes even better the next day as the flavors deepen. Perfect for Sunday meal prep or make-ahead lunches.

 

Refrigerator: 4–5 days in an airtight container

Freezer: Up to 3 months

Reheating: Add a splash of water or broth to loosen the texture

Variations & Tips

⭐ Make it heartier: Add diced sweet potato with the carrots

⭐ Boost the greens: Swap kale for spinach or Swiss chard

⭐ Add heat: Stir in a spoonful of harissa or top with hot sauce

⭐ Creamier version: Swirl in a little cashew cream (amazing for texture)

 

Because YOU Matter 💚

Every nourishing meal you make is an investment in your energy and well-being. This simple, comforting soup is proof that healthy food can be deeply satisfying and delicious. You deserve meals that help you feel strong from the inside out — today and every day.
