Put a good splash of oil and a knob of butter into a saucepan and heat on medium. Squash the garlic and when the butter melts add it to the pan with the thyme leaves

When the pan starts to sizzle add all of the onions with a pinch of salt and stir around to coat in the flavoured oil

Add a splash of oil then put the sausages in. Brown them on all sides

Remove the sausages and put the onions in an even layer on the bottom of the tin, then put the sausages back on top

Drain the potatoes and add into the pan the other knob of butter, milk, cream, mustard and season to taste. You may like more mustard. I make this quite mild so the kids won't say it's yucky lol

Put the roasting tin with the onions in back on the stove top. Pour off any excess fat. Add the flour to the onions and stir in

Add the stock then over a high heat let the gravy thicken. Scrape the good sticky bits from the bottom of the tin in, these hold all the flavour. Reduce down until you have a nice thick gravy

Serve with the sausages on top of a layer of mash with the gravy poured over and seasonal veg
