Prep the ingredients by slicing the garlic and grating the courgette.
Pop the spaghetti into salted simmering water with the timer two minutes shy of the packet time.
Add a tbsp of olive oil to a large non-stick saucepan. On a low heat, add the sliced garlic and red pepper flakes and GENTLY fry. Valentine’s is not the day to burn the garlic.
Stir in the courgette and increase the heat to medium. Season generously with salt to draw out the liquid that you’ll fry off.
Add the defrosted prawns and cook for a few minutes.
Before draining the pasta, reserve a mug full of pasta water. Transfer the spaghetti into the sauce with the reserved pasta water and stir.
Reduce the heat to low whilst you grate in the parm and the juice of half a lemon (use the whole if you both like lemon).
Plate up whilst twizzling the tongs to create a nice swirl effect. Season with salt, pepper and if you want it hotter add some more red pepper flakes.
