Spaghetti with Crab and Tomatoes

This vibrant spaghetti with crab and tomatoes is a sophisticated yet simple high-protein meal that celebrates fresh, coastal flavours. By combining sweet crabmeat with zesty lemon and juicy cherry tomatoes, you create a light, fragrant sauce that coats the pasta beautifully without the need for heavy cream. It is an ideal choice for a quick midweek dinner or an elegant weekend lunch when you want something that feels special but requires minimal time at the hob.

Packed with lean protein and heart-healthy fats from the extra-virgin olive oil, this pasta dish is as nutritious as it is delicious. The secret to the silky consistency lies in using the reserved pasta cooking water, which helps the oil and lemon juice emulsify into a delicate sauce. Serve it with a crisp green salad or some crusty sourdough for a complete and satisfying Mediterranean-inspired feast.
