Gluten-free Authentic Greek Roast Leg of Lamb with Lemon Potatoes (Αρνί στο φούρνο με λεμονάτες πατάτες)



A roast leg of lamb done right is easily a taste sensation!

And one thing for certain, it isn’t Easter (or Christmas in my home) without it! In Greece at Easter time, it's typical to roast a whole lamb on a 'souvla', or spit roast; I have memories when I was young taking turns with my grandparents and cousins to turn the spit by hand cooking it slowly for 5 or so hours. It was incredible. Thankfully there are now motorised spits, but this leg of lamb recipe is accessable for all!  

For me there is only one way to do lamb, and thats Greek style infused with garlic cloves, fresh rosemary, lemon juice and olive oil among other essentials.

Sadly I didn't get the chance to photograph the end result as I was busy in the kitchen and then ready to serve to my family, but gosh it smelt great and was deliciously succlent. I'll be sure to add a photo the next time I make it :)


8-10 Servings


15 Minutes


2 Hours


  • One leg of lamb 2 - 2.5kg, removed from the fridge at least one hour before roasting.

  • 5 cloves garlic, sliced in half lengthways

  • A few sprigs fresh rosemary

  • 1-2 Tbsp wholegrain mustard

  • 700g medium potatoes, peeled and cut into quarters 

  • 2 medium lemons, juiced

  • 5 Tbsp Greek extra virgin olive oil

  • 200ml water

  • 2 Tbsp dried Greek oregano

  • Sea salt and pepper, to taste

For the gravy: (optional)

  • Left over juices from the baking tray

  • 1 chicken or vegetable stock cube

  • a few glugs red wine

  • 100-150ml boiling water, if necessary

  • 2 tsp corn flour + 3 Tbsp cold water


  1. Preheat oven to 180ºC.

  2. Arrange the peeled and cut potatoes in a large baking tray, leaving a space in the centre for the lamb.

  3. Using a thin sharp knife, carefully cut slots into the top, bottom and sides of the lamb. Then insert the cloves inside so it's no longer visible.

  4. Season well with salt, pepper, 1 Tbsp olive oil and wholegrain mustard then massage into the flesh.

  5. Poke the rosemary sprigs inside the same slots as pictured.

  6. In a blender, add the lemon juice, oregano, olive oil and water and mix until it look creamy and opaque.

  7. Place the lamb in the centre of the potatoes, then pour the lemon mixture over the lamb and potatoes ensuring all the potatoes are covered with the juices.

  8. Cover the baking tray with aluminium foil and place on the lower shelf of the oven and cook for 1 and half hours. Remove the foil and cook for another 30 mins to get some colour. Check if you need to add a little water if you find it is becoming dry. 

  9. Remove from the oven.

  10. The potatoes can be placed onto the serving platter or bowl and placed back in the oven to keep warm while you make the optional gravy as the lamb rests for 10-15 mins before carving. Ensure the lamb is covered in foil.

For the gravy: (optional)

  1. Pour all the juices from the baking tray into a small saucepan and bring to a simmer. If you dont have enough juice or a lot is stuck to the bottom, pour 100-150ml of boiling water into the baking tray and use a wooden spoon to scrape the bottom. This is where all the flavour is, but avoid any burned areas. Then add this to the sauce pan too.

  2. Crumble in a chicken or vegetable stock cube and stir to combine. 

  3. Add a few glugs of red wine and simmer until the alcohol evaporates (we always have a bottle open to breath when lamb is on the menu) 

  4. To thicken the gravy, in a small bowl combine the corn flour with the cold water and stir until you get a cloudy mixture. It's important to mix with cold water and never pour flour directly into a sauce or gravy as it will not combine but create dumpling like clumps.

  5. Add this cornflour mixture to the sauce pan while stirring quickly with a whisk. It will begin to thicken. depending on how you like your gravy, for a thicker consistency mix another 1 tsp cornflower with 1 Tbsp water and repeat, or for a thinner consistency, add hot water until you reach your desired. When happy, remove from heat.

  6. Run the gravy through a sieve to rid of any lumps.

  7. Pour into your gravy jug and serve with the lamb, potatoes and any other vegetables like carrots, parsnips, broccoli, cauliflower etc.
