8 medium zucchini
1 medium Spanish onion
6 to 8 scallions
Leaves from 4 to 6 stems flat-leaf parsley
3 cloves garlic
6 tablespoons extra-virgin olive oil
1 1/4 teaspoons kosher salt, plus more as needed
3/4 teaspoon freshly cracked black pepper
About 6 large basil leaves, plus more for garnish
2 cups water, or more as needed
Freshly grated Parmigiano-Reggiano cheese, for garnish
Trim the zucchini ends, then cut into chunks. Finely chop the onion, scallions, parsley and garlic.
Heat 1/4 cup of the oil in a large Dutch oven over medium-high heat. Once the oil shimmers, add 1/3 of the zucchini and stir to coat. Cook for a few minutes, just until the bottom is golden and lightly caramelized, then transfer to a mixing bowl. Repeat (no need to add more oil) to use of all the zucchini.
Add the remaining 2 tablespoons of oil to the pot. Once it shimmers, add the onion-scallion mixture and stir to coat. Season with 1/4 teaspoon of the salt and 1/4 teaspoon of the pepper. Reduce the heat to medium; cover and cook for about 8 minutes, so the vegetables soften.
