Crisp the Pancetta: Add the diced pancetta to a large Dutch oven or soup pot. Cook over medium to medium-low heat, stirring often, until the pancetta is browned and crispy. Transfer it to a paper towel-lined plate, but leave the fat in the pot.
4 ounces pancetta
Make the Herb Bundle: Tie the thyme, oregano, and parsley sprigs together with kitchen string. Set the bundle aside.
3 sprigs fresh thyme, 3 sprigs fresh oregano, 3 sprigs fresh parsley
Cook the Vegetables: Add the onion, celery, garlic, and a small pinch of kosher salt to the pancetta fat. Cook for about 8 minutes, stirring often, until the vegetables are soft and fragrant.
1 medium yellow onion, 2 celery ribs, 4 garlic cloves, Kosher salt
Puree One Can of Beans: While the vegetables cook, add the undrained can of cannellini beans to a small food processor or blender. Blend until smooth.
1 15- ounce can cannellini beans
Add the Beans and Potatoes: Stir the pureed beans, drained whole beans, diced potatoes, Parmesan rind, and herb bundle into the pot with the vegetables.
2 15- ounce cans cannellini beans, 2 medium russet potatoes, 1 Parmesan rind
Pour in the Broth: Add the vegetable broth and stir well. Cover the pot, bring the soup to a simmer, then reduce the heat to medium-low or low. Cook for 25 to 30 minutes, stirring occasionally, until the potatoes are tender.
6 cups vegetable broth
Cook the Pasta: While the soup simmers, bring a separate pot of salted water to a boil. Add the ditalini and cook until al dente according to the package directions. Drain and set aside.
1 cup ditalini pasta
Remove the Rind and Herbs: When the potatoes are tender, remove and discard the Parmesan rind and herb bundle. If the soup looks too thick, stir in a little extra broth and warm it through.
Add Pasta and Pancetta: Stir the cooked ditalini and crispy pancetta back into the soup. Taste and season with more kosher salt if needed, then stir in the white pepper.
½ teaspoon white pepper
Serve the Soup: Ladle the soup into bowls. Top each serving with grated Parmesan cheese, minced parsley, and a light drizzle of extra virgin olive oil. Serve warm with crusty bread.
⅓ cup grated Parmesan cheese, Minced fresh parsley, 2 tablespoons extra virgin olive oil
