Place 2L of water and 1 tablespoon of salt in a Dutch oven or a heavy-bottomed pot, cover, and bring to a boil over high heat.
While the water is heating up, turn your broiler to 450F, and move one of the oven racks to the 2nd highest shelf.
Cut off the ends of 2 small zucchini or one large zucchini (500g), smash the zucchini a bit with a rolling pin or the bottom of a pan, and chop into rough fragments, approx ½ inch wide.
Toss the zucchini fragments in 1 teaspoon of avocado oil and ½ teaspoon salt in a bowl, and spread them out on an **unlined baking sheet** under the broiler to brown.
When the water comes to a boil, add 200g (2 cups) of dried pasta. Stir, and allow to cook according to the package instructions. Best to set a timer for this. The zucchini should take around the same amount of time as the pasta, but be sure to keep your eye on it too.
While the pasta and zucchini are cooking, finely chop 8 cloves of garlic, measure out 100 grams (⅓ cup) of Greek yogurt, and ¼ cup of basil leaves. Get your lemon and parmesan cheese ready too.
When the zucchini is softened, blistered, and golden brown, turn off the broiler and remove it from the oven.
When the pasta is cooked, pour 250 ml (1 cup) of the pasta water into a measuring jug, and drain out the remaining water using a colander.
Turn the burner off, and place the Dutch oven or pot back onto the still-warm burner.
Add 2 teaspoon of olive oil and 8 cloves of minced garlic into the Dutch oven, and stir for 30 seconds. If the garlic is browning/burning, add a splash of the pasta water to cool things off.
Into the Dutch oven with the garlic and olive oil, add the broiled zucchini, the drained pasta, the Greek yogurt, the zest of one lemon, 2 tablespoon of parmesan cheese, and 20 grams (½ cup) of fresh basil, tearing the leaves as you add them. Stir to combine using the pasta water to adjust the consistency as needed.
Taste for seasoning and add salt if needed. (I find it doesn’t usually need it).
Serve with lemon wedges, cracked black pepper, and more parmesan cheese as desired.
