This soup layers warm saffron and anise-bright fennel against the creamy, slightly nutty bite of lentils. A splash of citrus brightens the bowl so it never feels heavy, while a few fennel fronds add fresh perfume. The texture sits between silky and rustic — partially pureed lentils with tender vegetable ribbons. Serve it as a cozy weeknight dinner or a light starter for a dinner party.
Ingredients
- Olive oil (2 tablespoons)
- Yellow or red lentils (1 1/2 cups / 300 g), rinsed
- Fennel bulb (1 large), thinly sliced; fronds reserved for garnish
- Onion (1 medium), finely chopped
- Carrots (2 medium), diced
- Garlic (3 cloves), minced
- Vegetable stock (6 cups / 1.5 L), kept warm
- Saffron threads (a generous pinch, about 10–15 threads) soaked in 2 tablespoons warm stock
- Orange zest (1 teaspoon) and orange juice (1 tablespoon) or juice of 1 small orange
- Fresh thyme (1 teaspoon leaves) or 1 small sprig
- Bay leaf (1)
- Salt and freshly ground black pepper to taste
- Plain yogurt or crème fraîche (optional, for serving)
- Chopped parsley or fennel fronds for garnish
- Lemon wedges (optional, to finish)
Instructions
- Soak the saffron: place threads in 2 tablespoons warm stock and let steep while you prep the vegetables to release color and aroma.
- Heat oil in a large pot over medium heat. Add the onion and a pinch of salt, and cook until translucent, about 5 minutes.
- Add the garlic, sliced fennel and carrots. Sauté until the fennel softens and begins to caramelize at the edges, about 6–8 minutes.
- Stir in the lentils, thyme leaves and bay leaf, then pour in the warm stock and the saffron with its soaking liquid. Bring to a simmer.
- Reduce heat and simmer gently, partially covered, until the lentils are very tender, about 20–25 minutes. Skim any foam from the surface.
- Remove the bay leaf and purée roughly with an immersion blender, leaving some texture so the soup feels hearty. If you prefer a silkier finish, purée more completely.
- Stir in orange zest and orange juice, then season with salt and pepper to taste. If the soup is too thick, swivel in a little extra warm stock to reach desired consistency.
- Ladle into bowls and finish with a spoonful of yogurt or crème fraîche, a drizzle of olive oil, chopped parsley or fennel fronds, and a squeeze of lemon if you like extra brightness.
Tips or Variations
-
- For a meatier depth, stir in small cooked shrimp or shredded rotisserie chicken just before serving.
- Swap orange for lemon if you prefer a sharper citrus note; preserved lemon rind also pairs beautifully with saffron.
