01 - Pat the peeled and deveined shrimp dry with paper towels, then season lightly on both sides with salt and freshly ground black pepper.
02 - Heat 2 tablespoons of olive oil in a large skillet over medium-high heat. Once the oil shimmers, arrange the shrimp in a single layer and sear for 1 to 2 minutes per side until they turn pink and form a light golden crust. Remove promptly with tongs and transfer to a plate; set aside.
03 - Reduce the heat to medium and add the remaining tablespoon of olive oil to the skillet. Add the minced garlic and finely chopped onion, sautéing until the onion turns soft and translucent, approximately 3 minutes.
04 - Stir in the red pepper flakes and cook for about 30 seconds, allowing the heat to bloom and release their spicy aroma into the oil.
05 - Pour in the dry white wine, using a wooden spoon to scrape up any fond from the bottom of the skillet. Let the wine simmer for 2 minutes to reduce slightly and cook off the raw alcohol.
06 - Add the crushed tomatoes, stir to combine, and bring the sauce to a gentle simmer. Cook uncovered for 7 to 8 minutes, stirring occasionally, until the sauce thickens and coats the back of a spoon.
07 - Return the seared shrimp along with any accumulated juices back into the skillet. Add the chopped parsley and optional basil, tossing everything together. Cook for 2 to 3 minutes until the shrimp are heated through and infused with the sauce.
08 - Taste the sauce and adjust with additional salt, black pepper, or red pepper flakes according to your preference.
09 - Spoon the shrimp and spicy tomato sauce over a bed of cooked linguine or spaghetti. Garnish with extra fresh herbs and serve with lemon wedges on the side if desired.
