Savory Pancetta and Tuscan Vegetable Minestrone

Using a chef's knife and cutting board, dice the pancetta into 5 mm cubes, cut the onion, carrots, and celery into neat dice, mince the garlic, cube the peeled potato, slice the zucchini into quarter-moons, strip and ribbon the kale leaves, and drain the cannellini beans.

Place the heavy-bottomed Dutch oven or stockpot over medium-low heat at 150°C (300°F). Add the extra-virgin olive oil and diced pancetta, cooking for 6 minutes while stirring occasionally until the fat renders completely and the pancetta bits turn golden brown and lightly crisp.

Add the diced yellow onion, carrots, and celery into the rendered pancetta fat. Sauté over medium heat at 160°C (320°F) for 5 minutes, stirring with the wooden spoon, until the onions turn translucent and the mirepoix begins to soften.

Push the vegetables slightly to the perimeter to expose the center of the pot, then add the minced garlic and tomato paste. Fry for 2 minutes at 160°C (320°F), stirring continuously with the wooden spoon, until the tomato paste darkens to a deep brick red.

Pour the low-sodium chicken broth and hand-crushed plum tomatoes with their juices into the pot. Use the wooden spoon to scrape the caramelized browned fond cleanly from the bottom of the Dutch oven.

Add the cubed potato, Parmigiano-Reggiano rind, dried oregano, bay leaf, fine sea salt, and black pepper. Bring the liquid to a lively boil, then reduce heat to maintain a steady simmer at 95°C (203°F) for 8 minutes until the potatoes begin to soften but remain intact.

Stir in the dry ditalini pasta, rinsed cannellini beans, and zucchini quarter-moons. Simmer uncovered at 98°C (208°F) for 7 minutes, stirring frequently with the wooden spoon to keep the pasta from settling on the bottom, until the pasta is just al dente and zucchini is tender-crisp.

Add the chopped lacinato kale ribbons to the pot and submerge them into the simmering soup using the wooden spoon. Cook for 2 minutes until the kale wilts to an emerald green, then check with the instant-read food thermometer that the soup temperature exceeds 74°C (165°F).

Remove the Dutch oven from the heat. Use the wooden spoon to retrieve and discard the Parmigiano-Reggiano rind and the bay leaf, then stir in the torn fresh basil leaves and taste the broth to adjust salt or black pepper if needed.

Use the ladle to divide the hot minestrone evenly among six wide soup bowls, making sure each portion receives a balanced share of broth, pasta, pancetta, and tender vegetables. Sprinkle each bowl with the finely grated Parmigiano-Reggiano and serve immediately.
