A Note on Lentils
This recipe calls for brown or green lentils. They hold their shape well during cooking, giving the soup a pleasant texture. Red lentils can be used, but they tend to break down and will result in a much thicker, creamier soup. Both are delicious, so choose based on your preference!

Follow these simple stages to create a perfect pot of soup. Each step is designed to maximize flavor and ensure a delicious result every time.
Step 1: Build Your Flavor Base
The foundation of any great soup is the “mirepoix” – a mix of onion, carrots, and celery. We start by sautéing these in olive oil until they soften and the onion becomes translucent. This isn’t a step to rush! This process releases their natural sweetness. Adding garlic and dried herbs in the last minute prevents them from burning and unlocks their fragrant aromas.
Step 2: Simmer to Perfection
Next, we stir in the tomato paste and cook it for a minute to deepen its flavor. Then, in go the rinsed lentils, diced tomatoes, and vegetable broth. Bring the mixture to a boil, then immediately reduce the heat to a gentle simmer. Let it cook for 25-30 minutes, or until the lentils are tender but not mushy. This slow simmer is where all the flavors meld together into a harmonious, savory broth.
Step 3: Add Freshness at the End
Once the lentils are cooked, stir in the fresh spinach. It will look like a lot, but it wilts down in just a couple of minutes. This adds a boost of nutrients and a vibrant color. Finish the soup with a squeeze of fresh lemon juice or a splash of vinegar to brighten all the flavors. Don’t skip this step; it truly elevates the entire dish!

Expert Tips for a Perfect Pot Every Time
- Don’t Skip the Sauté: Properly sweating the mirepoix is crucial for building a deep, sweet flavor base.
- Use High-Quality Broth: Since vegetable broth is the primary liquid, using a flavorful one makes a significant difference.
- Rinse Your Lentils: Always rinse lentils before cooking to remove any dust or debris.
- Finish with Acidity: A splash of lemon juice or apple cider vinegar at the end brightens the entire soup and makes the flavors pop.
Delicious Variations to Try
This recipe is a fantastic starting point. Feel free to make it your own with these delicious additions and substitutions.
- Spice It Up: Add a pinch of red pepper flakes with the garlic for a little heat, or a teaspoon of smoked paprika for a smoky depth.
- Add More Veggies: Diced potatoes, sweet potatoes, or butternut squash can be added with the lentils for an even heartier soup.
- Make It Creamy: For a richer texture, stir in a splash of full-fat coconut milk at the end.
