Bring a large pot of water to a boil. Cook spaghetti, stirring occasionally, until just tender, 9 to 11 minutes or according to package directions. Drain.Advertisement
Meanwhile, heat oil in a large nonstick skillet over medium-high heat. Add garlic and cook, stirring, until fragrant, about 1 minute. Add anchovies (if using) and crushed red pepper and cook for 30 seconds more. Add tomatoes, reduce heat to medium and cook, stirring occasionally, for 8 minutes. Stir in tuna and cook until it is incorporated into the sauce and heated through, 2 minutes more. Divide the spaghetti evenly among 4 plates, top with sauce and garnish with basil. Serve hot.
Note: Chunk light tuna, which comes from the smaller skipjack or yellowfin, has less mercury than canned white albacore tuna. The FDA/EPA advises that women who are or might become pregnant, nursing mothers and young children consume no more than 6 ounces of albacore a week; up to 12 ounces of canned light tuna is considered safe.
