Instructions
In a large saucepan, heat 2 Tbls olive oil over medium heat until shimmering. Add red pepper flakes and garlic and cook, stirring, until garlic just begins to turn golden. Add onion and cook, stirring, just until softened, about 5 minutes. Add hand-crushed tomatoes and their juices, along with basil sprigs, and bring to a simmer.
Stir in bread. Ladle stock on top, one cup at a time, stirring to combine--initially adding two cups of stock. Simmer bread, adding more stock as needed (I added three cups total), until bread is completely softened and custardy and soup has thickened to a porridge-like consistency, about 25 minutes. Season with salt and pepper. Discard basil sprigs.
Spoon into bowls, generously drizzle with olive oil, and grind black pepper on top. Garnish with torn basil leaves and serve.
