Your Simple Ingredient Checklist

This recipe uses a handful of wholesome ingredients for its signature comforting flavor.

The Ingredient Lineup:

  • 3 Tbsp olive oil
  • 3 large carrots, roughly chopped
  • 1 yellow onion, quartered
  • 5 cloves garlic, peeled
  • 3 ribs celery, halved
  • 1 tsp salt and fresh black pepper to taste
  • 1 Parmesan rind (optional, for amazing flavor)
  • 8 cups chicken or vegetable broth

  • 1 large lemon, juiced (plus more to taste)
  • For Serving: Freshly grated Parmesan cheese, a drizzle of olive oil, and chopped parsley.

Step-by-Step Instructions

This simple one-pot method builds incredible, soothing flavor.

Part 1: Build the Flavor Base

  1. Sauté the Vegetables: Heat the olive oil in a large pot or Dutch oven over medium heat. Add the chopped carrots, onion, garlic, celery, salt, and pepper. Cook, stirring occasionally, for 4-5 minutes until the vegetables get a little color.
  2. Simmer the Soup: Add the Parmesan rind (if using) and the broth to the pot. Cover, increase the heat to high, and bring to a gentle boil. Once boiling, reduce the heat to medium-low and let it simmer, covered, for 25-30 minutes, or until the vegetables are very soft and tender.

Part 2: Purée and Finish

  1. Blend the Soup: Remove the Parmesan rind from the pot. Use an immersion blender to purée the soup directly in the pot until it is completely smooth and silky. (Alternatively, you can carefully transfer the soup in batches to a heat-safe blender, blend until smooth, and return it to the pot).
  2. Cook the Pasta: Bring the puréed soup back to a simmer. Add the pastina and cook for 8-10 minutes, stirring occasionally, until the pasta is tender.
  3. Add the Lemon: Turn off the heat and stir in the juice of one full lemon. Give it a taste and add more lemon juice, salt, or pepper as needed.
  4. Serve: Ladle the hot soup into bowls. Garnish generously with freshly grated Parmesan cheese, a crack of black pepper, a drizzle of good olive oil, and some fresh parsley.
