Optional: If your chops are very fatty you may wish to trim the excess. I like to leave some fat on as it keeps the chops moist and adds flavour.
Lie the chops in a large baking dish
Mix all the remaining ingredients together in a small bowl or jug.
Pour the marinade over the chops, chill in the firdge for two hours, turning the chops over after one hour. If you are short on time you can decrease the marinading time, the longer the better though, so overnight would be great if you have the time.
Heat your oven to 160 degrees Celsius (320 fahrenheit).
Cover the baking dish with foil and bake in the oven for 45 minutes.
Remove the foil from the baking dish, increase the temperature to 200 degrees celsius, (400 Fahrenheit). Turn the chops over, you can baste the chops (ie spoon the marinade over them) but I find turning them over just as good. At this stage the chops should be tender, the sauce will be quite thin but this will thicken up. Return the chops to the oven and bake for a further 15 minutes.
Serve the lamb chops with mashed potatoes/cauliflower purée and green vegetables, be sure to spoon the yummy sauce over the chops.
Notes
My one tip is to marinate the lamb chops for as long as you are able, otherwise, there isn't too much to know about this recipe
