Prep the shrimp (if frozen, add them to a colander and run under cool water until thawed). Leave tails on if you wish. Devein if needed. I suggest prepping every ingredient ahead of time since this recipe goes quick.
Boil a large, salted pot of water for the pappardelle. Cook al dente according to package directions. Important: You will need to reserve some hot pasta water prior to draining it.
When the pasta is about 5 minutes away from being cooked, add the olive oil to a skillet over medium-high heat. Once the oil is hot, add in the shrimp and cook for 2 minutes/side (or until pink and cooked through), then transfer them to a plate.
Reserve about a cup of the hot pasta water (you won't use it all) prior to draining the pasta.
Reduce the skillet heat to medium-low. Add in the garlic and cook for 30 seconds.
To the skillet, stir in the lemon juice + zest, parsley, Italian seasoning, and about 1/4 cup of the hot pasta water, then add in the drained pasta. Toss until coated. If needed, add a little more of the pasta water to make a nice sauce.
Add the shrimp to the skillet and sprinkle with the parmesan cheese. Serve immediately with extra salt & pepper as needed.
