Growing up my grandmother used to make roasts like this with either beef or lamb. It was full of garlic and spice and it was so tender it would fall apart. I always thought lamb made like this would be great for gyros or salads.
So when I saw a nice leg of lamb at Costco I decided to make this slow cooker lamb recipe. I stuffed it with garlic and roasted it all day until it was fall apart tender. It was soooo good! Reminded me of eating dinner at grandma’s every Wednesday.
Simple Ingredients For This Slow Cooker Lamb Recipe
This is a very simple recipe in that you only need a few ingredients and then you let your slow cooker do all the work! I used 5 cloves of garlic, thinly sliced to stud the roast. Then I used a spice blend of salt, pepper, oregano, thyme and marjoram. That’s all folks.
As I mentioned above, I got the lamb roast from Costco and it was about 4 lbs.
Making The Tender Lamb Roast Recipe
First thing you want to do is stud the lamb roast with garlic. Take a sharp paring knife and cut little slits all over the lamb and stuff them with slices of garlic. There are 5 cloves of garlic in this recipe so you need a lot of cuts.
Then mix your spices together in a bowl and rub them all over the lamb. Use all of the spices and get into the nooks and crannies (where did that expression come from?).
Now you are ready to cook the lamb.
How Long To Cook The Lamb Roast
I like to cook this on low all day but you could also cook it on high for less time if you want. Everyone’s slow cooker is different but you’ll know this is done when it’s fork tender.
One Important Note: Half way through the cooking, try to pour as much liquid out as you can. Reserve it for later if you feel it is too dry or if you want to make gravy. This will help the roast develop that brown crusty part that tastes soooo good.
If you don’t care about that no need to pour off the liquid. I personally love that part of any roast.
How To Eat This Slow Cooker Lamb
Now it’s time to eat this delicious, tender lamb. You can eat this meat as is with a few vegetable side dishes. Or you can also make a lamb salad as pictured below. I made some tzatzike sauce and topped my salad with it to make a gyro salad. It was awesome.
You can also make a gyro if you don’t care about carbs. Grab some pita bread and drop some lamb on it along with your favorite gyro toppings.
Looking For A Low Carb Tzatziki Sauce?
If you decide to eat this lamb as is or in a gyro, you might want have some tzatziki sauce. That is the sauce or topping you usually get when you buy a gyro and it goes great with lamb.
Usually it’s made with yogurt, cucumbers, garlic and olive oil. Sometimes people put herbs such as dill, mint, parsley in it.

Hi! I have a 1.78 lb boneless lamb sirloin–would this work for this recipe?
Denise
I don’t see why not Amanda. I will probably take less time but that’s easy to check with a slow cooker. Good luck and I hope enjoy it!

Plan to make your recipe for a dinner.
This might sound like a foolish question, but
I saw no mention of adding liquid to your recipe. Isn’t that necessary?
Denise
Hi June, that is not a foolish question. I used to think that too but the lamb will actually produce a lot of liquid with the juices and fat melting. You don’t want to add liquid to this recipe if you want that crusty outside.
You actually want to take the liquid that it produces out about half way through the cooking. I reserve it just incase the meat get’s dry and I pour a little bit back in. Hope that makes sense. 😉
