Begin by bringing a large pot of salted water to a boil. Add in your preferred pasta and cook according to the package instructions until al dente, usually about 8-10 minutes. Once cooked, reserve a cup of pasta water, then drain the rest.

In a large skillet over medium heat, pour in the heavy cream and allow it to warm up for about a minute. Add in the pesto, stirring until the two combine into a luscious green sauce.

Gently fold in the drained tuna, ensuring it is evenly distributed throughout the creamy mixture. Add salt and pepper to taste.

Add the drained pasta to the skillet, tossing to coat the noodles thoroughly with the sauce. If the mixture feels dry, add a splash of the reserved pasta water until the desired creaminess is reached.

Stir in the grated Parmesan cheese until melted and evenly mixed throughout the dish.

Top with fresh basil before serving. Enjoy immediately, and watch your loved ones rave about this dish!
