Freezer-Friendly: Yes!
You want a red lentil soup that’s easy on a weeknight, still tastes cozy, and reheats well – and that’s exactly what you’ll get here. Red lentils are truly a superstar ingredient. Unlike their brown or green cousins, red lentils cook down very quickly and naturally break apart, creating a wonderfully creamy texture without needing any heavy cream. This makes them perfect for a fast, comforting, and healthy soup base.
Red lentils are split lentils that have had their outer skin removed, which is why they cook so much faster than other varieties. When you’re shopping, you’ll typically find them labeled as “split red lentils.” What you can expect from them in this soup is a creamy texture that feels rich and satisfying, a super fast cook time that makes weeknight dinners a breeze, and a natural thickening as the soup sits (which is totally normal and delicious!).

Ingredients

• 1 tablespoon olive oil (preferably organic)
• 1 medium organic yellow onion, chopped
• 2 medium organic carrots, chopped
• 2 stalks organic celery, chopped (or similar aromatics like bell pepper)
• 2 cloves garlic, minced
• 1 (6 ounce) can organic tomato paste OR 1 (14.5 ounce) can organic diced tomatoes
• 1 teaspoon organic ground cumin
• 1 teaspoon organic smoked paprika
• 1/2 teaspoon organic turmeric (optional, for extra warmth and color)
• Pinch of cayenne pepper or red pepper flakes (optional, for gentle heat)
• 1 cup organic split red lentils, rinsed and picked through for debris
• 6 cups low-sodium organic vegetable broth or water
• 1 teaspoon salt (start here, adjust at end)
• 1/2 teaspoon black pepper, freshly ground
• Juice of 1/2-1 organic lemon (to finish)
• Optional: 2 cups fresh organic spinach or kale, roughly chopped

Directions

1. Sauté the Base Veg: Heat the olive oil in a large pot or Dutch oven over medium heat. Add the chopped onion, carrots, and celery. Sauté for 5-7 minutes, stirring occasionally, until the vegetables have softened and the onion is translucent. Add the minced garlic and cook for another minute until fragrant. This step builds the foundational flavor of your soup!
2. Toast Tomato Paste + Spices: Push the vegetables to one side of the pot. Add the tomato paste (or diced tomatoes) and the cumin, smoked paprika, and optional turmeric/cayenne to the cleared side. Cook, stirring the tomato paste and spices for 2-3 minutes, until fragrant and slightly darkened. This intensifies their flavor, making a big impact with little effort. Then, stir everything together with the sautéed vegetables.
3. Add Red Lentils + Broth/Water: Stir in the rinsed red lentils, followed by the vegetable broth or water. Add the initial teaspoon of salt and pepper. Bring the mixture to a rolling simmer over medium-high heat.
4. Simmer Until Lentils Collapse: Once simmering, reduce the heat to low, cover the pot, and let it cook for 15-20 minutes, or until the red lentils have completely collapsed and the soup has thickened. Give it a stir every now and then to prevent sticking. You’ll know they’re ready when the soup looks thick and creamy.
5. Blend Briefly (Optional but Recommended): For an ultra-smooth texture, you can use an immersion blender directly in the pot. Blend for just 30-60 seconds, or until you reach your desired consistency. If using a regular blender, carefully transfer a few ladles of soup to the blender (filling it only halfway), secure the lid, and blend until smooth. Return the blended portion to the pot. Be cautious when blending hot liquids!
6. Finish with Lemon & Greens: Remove the pot from the heat. Stir in the fresh lemon juice. If using, add the optional spinach or kale and stir until wilted (this only takes a minute or two). Taste the soup and adjust the seasoning with more salt, pepper, or lemon juice as needed.
7. What it should look/taste like:
   1. Thickness: The soup should be thick and creamy, but still pourable. If it's too thick, add a splash of extra broth or water.
   2. Balance: Expect a savory, earthy flavor from the lentils and spices, brightened by the lemon.
   3. Adjustments: If it tastes flat, add more salt. If it needs a lift, a bit more lemon juice will do the trick.
