Author Notes

Rich and nutty pistachios are ground alongside fennel, basil, and tarragon to make this delicious herbal pesto, which is then mixed with ricotta and layered with lasagna noodles and lots and lots of Parmesan and white cheddar.

What You'll Need
  • For the fennel-pistachio pesto
  • 3 cups (228 g) coarsely chopped fennel stems and fronds
  • 1 cup (120 g) shelled, salted, and roasted pistachios
  • 1/2 cup (20 g) fresh basil leaves
  • 1/4 cup (13 g) coarsely chopped fresh tarragon
  • 3/4 teaspoon flake kosher sea salt
  • 1/2 teaspoon freshly ground black pepper
  • 1/2 cup plus 1 tablespoon (135 ml) extra-virgin olive oil
  • For the lasagna
  • 1/2 pound (225 g) lasagna noodles
  • 2 cups (480 ml) fresh full-fat ricotta
  • 1/2 cup (120 ml) heavy cream
  • 4 cups grated Parmesan cheese
  • 1 cup (115 g) grated white cheddar cheese
  1. For the pesto, in a blender or food processor, combine the fennel, pistachios, basil, tarragon, salt, and pepper and blend until smooth. With the motor running, slowly add the oil in a thin, steady stream through the hole in the cap or feed tube. Blend for 10 seconds more, or until thick and smooth. Cover and set aside.
  2. Preheat the oven to 375°F (190°C).
  3. For the lasagna, bring a large pot of water to a boil. Place the lasagna noodles in the water, working in batches as necessary, and cook until slightly bendable, 4 to 5 minutes. Remove with tongs and transfer to a colander to drain.
  4. In a medium bowl, mix the pesto, ricotta, and cream together until combined.
  5. Place 3 or 4 of the noodles in the bottom of a 9 by 13-inch (23 by 33-cm) rectangular casserole dish, keeping them in a flat, even layer. Take 1 cup (100 g) of the Parmesan and set it aside for later use. Spread one-third of the ricotta mixture over the noodles, then sprinkle with one-third of the Parmesan. Place 3 or 4 noodles in an even layer on top of the Parmesan and repeat two more times, so you have three layers of the ricotta mixture and are left with the noodles on top.
  6. Sprinkle the cheddar and reserved Parmesan evenly over the top. Place the casserole dish on a baking sheet and place it in the oven. Bake until the cheese is bubbling around the edges, about 35 minutes. Allow to cool for 15 minutes before slicing and serving.

Kinda needs a protein, otherwise is a bit bland. I added some chicken and apple sausage to one of the lasagnas and it was great

This looks and sounds delicious except that tarragon doesn't go over well in our home. In it's place would you suggest more basil? Something else?

I love the idea of the pesto but for some reason the cheddar does not appeal to me in this recipe. Is there anything else you might suggest- or is there a specific rationale (taste profile) that explains the cheddar? Thank you!

I used shredded mozzarella instead of the cheddar & it was delicious!

I love how you make a pesto of fennel and pistachios in this recipe. It sounds so good with the creamy ricotta, too.
