Ingredients

• 1 tablespoon extra-virgin olive oil
• 1 large yellow onion, chopped
• 2 medium carrots, peeled and diced (optional extra carrot for sweetness)
• 2 celery stalks, diced
• 4 cloves garlic, minced
• 1 teaspoon ground cumin
• ½ teaspoon ground coriander (optional)
• Pinch of cinnamon (optional)
• ¼ teaspoon freshly ground black pepper
• 1 cup brown or green lentils, rinsed and picked over
• 6 cups low-sodium vegetable or chicken broth (check labels for ~140mg sodium per cup or less)
• 2 cups water
• 1 bay leaf
• ½ teaspoon salt, or to taste (use a tiny pinch to start, add more at the end if needed)
• 5 ounces fresh spinach (or baby spinach), rinsed and roughly chopped if leaves are large
• ¼ cup fresh lemon juice (from 1-2 lemons), plus more to taste
• 1 tablespoon lemon zest (optional)
• ¼ cup fresh parsley or cilantro, chopped (optional, for garnish)

Directions

1. Prep Everything: Start by getting all your ingredients ready. Chop the onion, carrots, and celery into small, even pieces. Mince the garlic. Rinse your lentils thoroughly under cold water and pick out any small stones or debris. Rinse the spinach and give it a rough chop if the leaves are large. Finally, zest your lemons (if using) and then juice them; set both aside. This "mise en place" makes the cooking process smooth!
2. Build the Flavor Base: Grab a large, heavy pot or Dutch oven and heat the olive oil over medium heat. Add the chopped onion, carrots, and celery along with a small pinch of salt. Sauté, stirring occasionally, for 8-10 minutes until the vegetables have softened and are just starting to turn lightly golden. Stir in the minced garlic and cook for another minute until it's fragrant – be careful not to let it burn. Next, add the ground cumin (and optional coriander or cinnamon) and black pepper. Stir constantly for about 30 seconds to "toast" the spices, which really helps to bloom their flavors.
3. Simmer the Lentils: Pour in the rinsed lentils, low-sodium broth, water, and add the bay leaf. Add a small pinch of salt (remember, you can always add more later, but you can’t take it out!). Bring the mixture to a boil over medium-high heat. Once boiling, reduce the heat to a gentle simmer, partially cover the pot, and cook for 20-25 minutes, or until the lentils are just tender but still hold their shape. Stir occasionally to prevent sticking. If you prefer a slightly thicker soup, carefully mash a scoop of cooked lentils against the side of the pot with the back of a spoon, or give the soup 3-4 short pulses with an immersion blender (don't over-blend, or you'll get a puree!).
4. Add Spinach & Lemon: Once the lentils are tender, stir in the fresh spinach. Simmer for just 2-3 minutes, stirring gently, until the spinach has wilted and turned a vibrant green. Remove the pot from the heat. Now, stir in the fresh lemon juice (start with about half of the prepared amount and add more to taste) and any optional chopped fresh herbs like parsley or cilantro.
5. Taste & Adjust: This is crucial! Taste the soup for seasoning. Does it need more salt? Another squeeze of lemon if it tastes a bit flat? A dash more black pepper? Adjust according to your preference. For the best flavor, let the soup rest for 5-10 minutes before serving; this allows the flavors to meld beautifully.
