Creamy Fettuccine with Peas and Basil

This creamy fettuccine with peas and basil is a wonderful example of how simple, plant-based ingredients can create a truly indulgent meal. The sauce relies on a clever combination of cashew butter and oat milk to achieve a silky, velvet-like texture without the need for dairy. Brightened by the sweetness of garden peas and the aromatic lift of fresh basil, it is a vibrant dish that feels both comforting and light, perfect for a quick weeknight supper or a relaxed weekend lunch.

As a nutritious vegan main course, this recipe uses whole-wheat pasta for an earthy flavour and extra fibre. It is an ideal choice for those seeking a heart-healthy, cholesterol-free alternative to traditional Italian cream sauces. For a complete meal, serve this pasta in warm bowls with a side of crisp green salad or some charred tenderstem broccoli to complement the fresh, herby notes.
