Bring a large pot of salted water to a boil and cook the linguine according to package directions until al dente.
Reserve 0.25 cup of the starchy pasta water before draining the noodles.
Season the peeled and deveined shrimp with sea salt and black pepper.
Heat the olive oil in a large skillet over medium-high heat and sear the shrimp for 2 minutes per side until pink and opaque.
Remove the shrimp from the skillet and set aside on a plate.
In the same skillet, add the minced garlic, halved cherry tomatoes, and Calabrian chili paste, sautéing for 2 minutes until fragrant.
Deglaze the pan with the fresh lemon juice, using a wooden spoon to scrape up any flavorful browned bits.
Add the cooked linguine, reserved pasta water, and seared shrimp back into the skillet.
Toss everything together over medium heat for 1 minute until the sauce is glossy and coats every strand of pasta.
Remove from heat and garnish with fresh parsley and lemon zest before serving immediately.
