Red Lentil Soup with Lemon & Spinach
A nourishing, one-pot favorite — light, comforting, and full of citrusy brightness.
🛒 Ingredients
3 tablespoons olive oil (plus more for serving)
1 large onion, chopped
2 garlic cloves, minced
1 tablespoon tomato paste
1 teaspoon ground cumin
¼ teaspoon kosher salt (plus more to taste)
¼ teaspoon ground black pepper
Pinch of cayenne or chili powder (optional, to taste)
1 quart vegetable or chicken broth
1 cup red lentils
1 large carrot, peeled and diced
A few handfuls of baby spinach
Juice of ½ a lemon (or more to taste)
Chopped fresh cilantro, for serving (optional)
👩🍳 Instructions
In a large pot, heat the olive oil over medium heat. Add the onion and garlic, and sauté until soft and golden — about 4 minutes.
Stir in the tomato paste, cumin, salt, pepper, and cayenne, and sauté for 2 more minutes to bring out the flavor.
Add the broth, lentils, and diced carrot. Bring to a simmer, partially cover the pot, and cook on medium-low heat for 25–30 minutes, until the lentils are soft.
Stir in a few handfuls of baby spinach during the last few minutes of cooking — just until wilted.
Use an immersion blender (or regular blender) to purée half the soup — then return it to the pot. This keeps it comforting and a little chunky.
Stir in the lemon juice, taste, and adjust seasoning if needed.
Serve warm with a drizzle of olive oil, a sprinkle of fresh cilantro (if using), and maybe some crusty bread on the side.
🌱 Note from Sylvie
This is one of my favorite go-to soups — it’s simple, grounding, and comes together fast. I often make a big batch on Sundays and eat it all week. The lemon brightens everything, and the spinach adds that little boost of green goodness.
