How to Make It
Bring a large pot of salted water to a boil. Add the green beans and cook until tender, about 10 minutes. Using a slotted spoon, transfer the beans to a plate. Bring the water back to a boil.
Meanwhile, in a large skillet, heat the olive oil. Add the garlic and crushed red pepper and cook over moderate heat until fragrant, about 1 minute. Add the chopped tomatoes and season with salt and pepper. Cook, stirring occasionally, until the tomatoes begin to break down, about 5 minutes. Add the white wine and clams and bring to a boil. Cover the skillet and simmer until the clams open, about 5 minutes. Remove the skillet from the heat and add the green beans and basil.
Add the spaghetti to the boiling water and cook until al dente. Drain the spaghetti, reserving 1/4 cup of the cooking water. Return the spaghetti to the pot and add the clamandgreen bean sauce and the reserved pasta cooking water. Toss over moderate heat until the sauce coats the spaghetti, about 1 minute. Transfer the spaghetti and clams to shallow bowls and serve, passing the grated Parmigiano- Reggiano at the table.
