Pumpkin & Kale Pesto Lasagne with Crispy Sage Recipe

Sweet roasted pumpkin, Tuscan kale and walnut pesto, silky béchamel, and crispy sage layered between fresh pasta sheets. This is a cozy, cold-weather lasagne that feels generous and comforting without being heavy. I developed this dish with my vegetarian friend in mind and it’s now become one of those dishes that has earned a permanent place in my rotation.

Pumpkin & Pesto Lasagne with Crispy Sage

(Serves 4)

Roasted Pumpkin

Ingredients

  • 1 small butternut pumpkin, peeled and sliced into thin rounds

  • Olive oil

  • Kosher salt

  • Freshly cracked black pepper

Method

  1. Preheat the oven to 400°F (200°C).

  2. Lay the pumpkin slices on a baking tray. Drizzle with olive oil and season with salt and pepper.

  3. Roast until tender and lightly caramelized, about 25–30 minutes. Set aside.

Fresh Lasagne Sheets

Ingredients

  • 400g all-purpose flour

  • 4 whole eggs

  • 2 egg yolks

  • Pinch of salt

Method

  1. Place the flour on a clean work surface and make a well in the center. Add the eggs, egg yolks, and salt.

  2. Using a fork, gently whisk the eggs, slowly incorporating the flour from the edges.

  3. Once it comes together, knead until smooth and elastic, about 8–10 minutes.

  4. Wrap tightly and rest at room temperature for at least 30 minutes.

  5. Roll the dough out into thin sheets using a pasta machine or rolling pin.

  6. Cut into lasagne-sized sheets.

  7. Bring a large pot of well-salted water to a boil. Blanch the pasta sheets for 30–45 seconds.

  8. Transfer immediately to an ice bath to stop the cooking, then lay flat on clean kitchen towels.
