Step 1

In a 10-inch skillet over medium-high, toast the almonds, stirring frequently, until golden brown and fragrant, 3 to 5 minutes. Transfer to a small bowl and set aside; reserve the skillet.

Step 2

In a large pot, bring 4 quarts water to a boil. Add the pasta and 2 tablespoons salt, then cook, stirring occasionally, until al dente. Reserve about ½ cup of the cooking water, then drain the pasta.

Step 3

Meanwhile, in a food processor, process ½ cup of the almonds, the garlic and 2 teaspoons salt until finely chopped, about 30 seconds. Add the basil and half of the tomatoes, then pulse until chopped and well combined, 4 to 6 pulses. Add the remaining tomatoes and 2 tablespoons of oil, then pulse just until the whole tomatoes are broken up, about 3 pulses. Transfer to a serving bowl, add the pasta and ¼ cup of the reserved cooking water, then toss. Let stand, tossing once or twice, for 10 to 15 minutes to allow the pasta to absorb some of the sauce.

Step 4

While the pasta stands, in the same skillet used to toast the almonds, toss the bread, remaining 4 tablespoons oil, ½ teaspoon salt and ¼ teaspoon pepper. Cook over medium, stirring frequently, until the bread is crisp and golden brown, 5 to 7 minutes.

Step 5

Scatter the toasted bread and the remaining ¼ cup almonds over the pasta. Drizzle with additional oil and sprinkle with pepper.
