This creamy shrimp pesto pasta has become my go to when I need something fast flavorful and impressive. The sauce is rich with a hint of heat and the pesto gives it a fresh herbaceous punch. You can have it on the table in twenty minutes and it always disappears fast.
I first made this after a long day when I needed a comforting meal fast and it’s been a weeknight favorite ever since.
