Slice the zucchini lengthwise 1/8 inch or 3 mm.
In a small cup place 2 tablespoons of olive oil. With your fingers grease the zucchini slices on both side and place them on a parchment paper on a baking sheet, one next to the other.
Broil in the oven to 400F/180C for 10 minutes. Flip them on the other side and keep broiling for additional 5 minutes.
Remove three slices and set them apart.
Place all the others in a food processor all together with the other ingredients: pistachios + 4 Tbsp olive oil + smoked ricotta +garlic.
Blend to obtain a creamy consistency.
Fill a small pot with water and bring to boil. When the water is boiling add the pasta and cook following the cooking time on the packaging. Drain.
In a bowl/cup add the pasta and one tablespoon of zucchini pesto. Mix and serve warm to your little one.
