Pasta with Lentils and Kale

This pasta with lentils and kale is a deeply satisfying vegetarian dish that transforms simple store-cupboard staples into a nutritious and flavourful meal. The secret lies in the slow-caramelised onions, which provide a sweet, savoury base that perfectly complements the earthy tones of the small green lentils and the robust texture of Tuscan kale. It is an excellent way to enjoy more plant-based protein while making use of seasonal greens.

Ideal for a comforting midweek dinner, this recipe is both wholesome and heart-healthy. By cooking the pasta in the same water used for the kale, you infuse every strand with extra nutrients and flavour. Serve it simply with a drizzle of high-quality extra-virgin olive oil and a generous sprinkling of toasted breadcrumbs or salty Parmigiano-Reggiano for a truly authentic homemade finish.

Ingredients for Pasta with Lentils and Kale

  • 120ml French (small) green lentils

  • 475ml water

  • 3/4 teaspoons salt

  • 6 tablespoons extra-virgin olive oil

  • 1 large onion, finely chopped (2 cups)

  • 1/4 teaspoons black pepper

  • 350g kale (preferably Tuscan

  • sometimes labeled "lacinato")

  • 350g dried short pasta

How to make Pasta with Lentils and Kale

Simmer lentils in water (475ml ) with 1/4 teaspoons salt in a 1- to 1 1/2-quart saucepan, uncovered, adding more water if necessary to keep lentils barely covered, until tender but not falling apart, 20 to 25 minutes. Remove from heat and season with salt.

While lentils simmer, heat 60ml oil in a 12-inch heavy skillet over moderately high heat until hot but not smoking, then sauté onion with pepper and remaining 1/2 teaspoons salt, stirring, 1 minute. Reduce heat to low and cook, covered, stirring occasionally, until onions are soft and golden (stir more frequently toward end of cooking), about 20 minutes. Remove lid and increase heat to moderate, then cook, stirring frequently, until onion is golden brown, 5 to 10 minutes more.

While onion cooks, cut out and discard stems and centre ribs from kale. Cook kale in a 6- to 8-quart pot of boiling salted water , uncovered, stirring occasionally, until just tender, 5 to 8 minutes. Transfer kale with tongs to a colander to drain, pressing lightly. Keep pot of water at a boil, covered.

Coarsely chop kale and add to onion along with lentils (including lentil-cooking liquid), then simmer, stirring, 1 minute. Season with salt and pepper.

Add pasta to kale-cooking liquid and boil, uncovered, until al dente. Reserve about 240ml pasta-cooking liquid, then drain pasta in a colander. Add pasta to lentil mixture along with about 80ml pasta-cooking liquid (or enough to keep pasta moist) and cook over high heat, tossing, 1 minute. Season with salt and pepper and drizzle with remaining 2 tablespoons oil.
