Ingredients
1X 2X 3X
6 ounces ciabatta, plus more for garnish (about ½ large loaf)
Extra virgin olive oil
½ teaspoon red pepper flakes
4 garlic cloves, thinly sliced
1 small yellow onion, finely chopped
1 (28-ounce) can whole San Marzano tomatoes
4 sprigs fresh basil, plus chopped basil leaves for garnish
2 to 3 cups vegetable broth (or chicken broth), warmed
Kosher salt
Black pepper
Directions
1
Prepare the ciabatta. Slice the ciabatta in half lengthwise, then use your hands to pull off and tear the center into small pieces (or you can cut it into 1-inch cubes). If you’re working with very dry stale bread, skip to the next step. Otherwise, spread onto a sheet pan and drizzle with olive oil. Toss to coat, then broil on high until golden, about 2 minutes. Set aside.
2
Sauté the vegetables. In a medium saucepan, heat 2 tablespoons olive oil over medium heat until shimmering. Add the red pepper flakes and lower the heat to medium-low. Add the garlic and onions and cook over medium-low heat, stirring occasionally, until the mixture is lightly golden (do not let it burn or turn dark brown), 10 to 15 minutes.
3
Meanwhile, make large rustic tomato chunks. When the onions are lightly golden, use your hands dig out the tomatoes from the can and burst them into large chunks over the pan. Pour in the juices from the can, then add the basil sprigs. Turn the heat to high to bring to a simmer.
4
Simmer. When the soup is simmering, stir in the bread and 2 cups of broth. Lower the heat to medium-low and simmer, stirring occasionally and adding more broth if needed, until the bread is very soft and you have a thick porridge-like consistency—about 20 to 30 minutes.
5
Finish and serve. Taste and season with salt and pepper to your liking. Remove the basil sprigs, then ladle the soup into bowls and drizzle with a generous amount of olive oil. Garnish with chopped basil and torn bread and serve.
