Step 1

1 Set a large Dutch oven or stockpot over medium-high heat and add 1 tablespoon olive oil

2 When the oil shimmers, add the pancetta, if using, and cook, stirring for 1 minute, until it just begins to brown

Step 3

3 Add the onion, celery, carrots and bay leaves

Step 4

4 Season generously with salt and pepper

Step 5

5 Reduce the heat to medium and cook, stirring occasionally, until the vegetables are tender and just starting to brown, about 15 minutes

Step 6

6 Dig a little hole in the center of the pot, then add another tablespoon of olive oil

Step 7

7 Add the garlic and let it sizzle gently until it gives off an aroma, about 30 seconds

Step 8

8 Before the garlic has a chance to brown, add the tomatoes

Step 9

9 Stir, taste, and add salt as needed

11 Add two immoderate splashes of olive oil, about 1/4 cup

Step 16

16 I like this soup to be very thick, but add more liquid if you like a lighter soup

Step 17

17 Remove the Parmesan rind and bay leaves
