Spicy shrimp pasta is a fiery dish that is not for the faint of heart. The dish is made by sautéing shrimp in olive oil and garlic and then tossing it with cooked pasta and a spicy tomato sauce made from crushed red pepper flakes, diced tomatoes, and tomato paste. The sauce is thick and chunky, and it packs a serious punch. You can also add other ingredients like bell peppers, onions, or jalapeños to make the dish even spicier.
