I love to use orzo to make quick creamy pasta after a busy day at work, but you can use this sauce with any kind of pasta. I like to make my own Cajun spice mix as ready-made mixes often contain added salt, but if you don’t think you’ll use up all the individual spices, then take the ready-made option – just check the label to ensure it’s not too salty.
Based on 2 servings, adjust as needed.
Defrost the prawns if using frozen. Boil the orzo following pack instructions. Drain, reserving a cup of the cooking water. For the Cajun spice mix, combine the turmeric, garlic granules, dried oregano or thyme, ground cumin, ground coriander and smoked paprika in a small bowl and set aside.
Heat the oil in a large, ovenproof pan over medium heat. Fry the onions until soft and lightly browned. Add the garlic and fry for 1 min, stirring so it doesn’t burn.
Add the tomato purée, prawns and Cajun spice and fry for 1 min.
Stir in the baby spinach, some salt and pepper, and cook until the spinach wilts and the prawns turn opaque. Stir in a splash of the reserved pasta cooking water, if needed, to loosen the sauce.
Stir in the cooked orzo and crème fraîche, adding more pasta water as needed to adjust the consistency. Serve straightaway.
