Ingredient Notes

Here’s a closer look at the key ingredients you’ll need:

• Lentils: Red lentils cook the fastest and create a creamy texture, while green or brown lentils hold their shape more. Use what you have, but note red lentils are the best for a smoother soup.

• Lemon Juice: Freshly squeezed lemon juice is essential. Bottled juice won’t give the same bright, fresh flavor.

• Onion and Garlic: These form the flavor base. You can use yellow onion or white onion. Garlic powder works in a pinch, but fresh is best.

• Carrots and Celery: Classic soup veggies that add sweetness and balance. If you don’t have celery, you can skip it.

• Spices: Cumin and turmeric add warmth and depth. A pinch of red pepper flakes or cayenne is optional for heat.

• Vegetable Broth: Use low-sodium broth so you can control the salt. You can also use chicken broth if not making it vegan.

• Olive Oil: Adds richness and helps develop the base flavors.

• Fresh Herbs: Parsley or cilantro brighten the soup at the end.

Optional extras: A bay leaf for simmering, a splash of coconut milk for creaminess, or even spinach stirred in before serving.

How To Make Lemon Lentil Soup

1. Sauté the Aromatics
   Heat 2 tablespoons olive oil in a large pot over medium heat. Add 1 diced onion, 2 diced carrots, and 2 diced celery stalks. Cook for 5–6 minutes until the vegetables soften and the onion turns translucent. Add 3 minced garlic cloves and cook another minute until fragrant.

2. Add Spices and Lentils
   Stir in 1 teaspoon ground cumin, 1 teaspoon turmeric, and 1 cup rinsed red lentils. Toasting the spices for 30 seconds helps release their flavor.

3. Pour in Broth and Simmer
   Add 6 cups vegetable broth (or chicken broth if preferred). Bring the soup to a boil, then reduce heat to low and simmer uncovered for about 25 minutes, stirring occasionally. The lentils should become tender and slightly break down, thickening the soup.

4. Add Lemon and Adjust Seasoning
   Once the lentils are soft, stir in the juice of 2 lemons (about 1/4 cup). Taste and season with salt and black pepper. Add more lemon juice if you love extra tang.

5. Finish and Serve
   Garnish with chopped parsley or cilantro. Serve hot with warm pita bread or crusty sourdough.

Tip: If you like a creamier soup, use an immersion blender to puree half of it, leaving some chunks for texture.
