Basil pesto adds zip to this pasta main-dish recipe topped with scallops. It takes just over 30 minutes to prepare.
Cook pasta following package directions, about 10 minutes. Drain, reserving 1 cup of the cooking liquid.
While pasta is cooking, season scallops with salt and pepper. Heat olive oil in a large nonstick skillet over medium-high heat. Sauté 3 to 4 minutes per side, until cooked through and no longer translucent.
Add the pesto to drained pasta. Stir in some of the reserved cooking liquid until pasta is evenly coated with pesto.
Stir in the cheese and the toasted walnuts. Serve with the scallops, and garnish with fresh basil, if desired.
