  • 1/2 cloves Garlic

Method

  • First, blanch the lasagna noodles for a couple of minutes in a pot of salted boiling water.
  • Then drain them (keeping some hot water for the pesto sauce) and dry the pasta sheets on a cloth.
  • Put all the ingredients for the pesto sauce in a blender and blend until you have a smooth sauce.
  • If the sauce is too thick add some more water.
  • The final result has to be rather fluid because the lasagna will need some moisture for the baking.
  • For the bechamel sauce: Heat the milk in a pot over medium low heat.
  • In a saucepan melt the butter over medium heat then whisk in the flour.
  • When the butter and the flour are well mixed, start to pour in little by little the hot milk whisking all the time.
  • You should obtain a thin sauce without lumps.
  • Now, if you have a microwave, transfer the sauce into a microwave safe bowl and put it in the microwave at maximum power for 2 minutes.
  • Then take it out, whisk it and put it back in the microwave for another 2 minutes.
  • Whisk again and if the sauce is too thin repeat the process one last time.
  • If you do not have a microwave, put the saucepan back on the stove at low/medium heat and bring the sauce to boil whisking all the time.
  • When the sauce has thickened, take it from the stove.
  • Finally, season the bechamel sauce with salt and ground nutmeg, and let it cool.
  • Peel the boiled potatoes and cut them into slices of around 1 cm thickness.
  • Mix the pesto sauce with 2/3 of the bechamel sauce (set the other 1/3 of the bechamel sauce aside).
  • Taste and add more salt if necessary.
  • You will use the rest of the bechamel sauce for the topping.
  • Preheat the oven at 200 degrees C.
  • Grease a baking dish (35x25x7 cm or similar) with 2-3 tablespoons of butter.
  • Put down a first layer of pesto sauce, followed by one layer of lasagna noodles and finally one layer of boiled vegetables (French beans and potatoes).
  • Repeat these layers until you finish your ingredients, the last layer has to be a layer of lasagna noodles.
  • Top the lasagna with the reserved bechamel sauce that you previously put aside.
  • Lastly garnish with some butter chunks and sprinkle with grated Parmigiano cheese.
  • Put the lasagna in the oven on the middle rack and bake it for 40 minutes.
  • The lasagna is ready when the top is a nice golden crust.
  • Serve it hot.
  • You can prepare the lasagna the day before and bake it only at the last moment.
