• Boil a large pot of salted water for the rigatoni.
• When boiling, add the rigatoni to the water and bring back to the boil.
• Cook until softened, 12 mins.
• Once cooked, drain in a colander and pop back in the pot.
• Drizzle with oil and stir through to stop it sticking together.

TIP: If you’re in a hurry you can boil the water in your kettle.

• Meanwhile, trim the courgette, halve lengthways and slice into 1cm half-moons.
• Roughly chop the parsley (stalks and all).
• Zest half the lemon (double for 4p). Cut into thick wedges. 
• Peel and grate the garlic (or use a garlic press).

• Place a large pan over high heat (no oil).
• Once hot, add the courgette and cook until starting to brown, 3-4 mins on each side.
• Add the garlic and cook, stirring, for 1 min.

• Once the courgettes are browned, reduce the heat.
• Add the creme fraiche, 50ml water (double for 4p) and stock to the pan. 
• Season with salt and pepper and stir to combine. 
• Bring to a simmer and cook until the sauce has thickened slightly, 3-4 mins.

• Stir the prawns into the sauce.
• Continue to simmer until the prawns are cooked through, 4-5 mins. IMPORTANT: The prawns are cooked when pink on the outside and opaque in the middle. 
• Add a splash of water if the sauce is a bit thick.
• Meanwhile, mix together the lemon zest and remaining parsley in a small bowl.

• Toss the drained rigatoni in the sauce. 
• Season to taste with a squeeze of lemon juice, salt and pepper.
• Serve in bowls garnished with the lemon and parsley topping.
