Growing up my grandmother used to make roasts like this and they were full of garlic slivers and spices. The meat was so tender it would fall apart. I imagine she cooked them all day in the oven. I always thought lamb made like this using Greek flavors would be great for gyros or on top of lettuce for a low carb gyro salad.
So when I saw a nice leg of lamb at Costco I decided to make this slow cooker Greek lamb recipe. I stuffed it with garlic, rubbed it with seasonings and roasted it all day until it was fall apart tender. This succulent roast lamb was soooo good! Reminded me of eating dinner at grandma’s every Wednesday.
My husband ate it as a gyro and I had it on a salad for a low carb dinner and we both loved it. So next time you are looking for a lamb recipe give this one a try. Slow cooking makes this delicious meal a breeze.
Recipe ingredients and substitutions.
This is a very simple recipe in that you only need a few simple 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.
Lamb Roast
As I mentioned above, I got the boneless lamb leg from Costco and it was about a 4 pound roast. You can use boneless lamb shoulder or a leg of lamb but I prefer boneless as that is easier to use for gyros. But bone in would also work.
Fresh Garlic
You need fresh garlic cloves for this recipe to stud the roast. You will cut slits into the meat and stuff slices of garlic. You will be amazed at how much flavor this adds.
Seasonings and Spices
I like this combination of oregano, thyme and marjoram. These Greek spices give the meat that gyro flavor. And the salt and black pepper of course. You might not have marjoram on hand so if not add a bit more oregano.
Note: I used dried oregano and spices. If you want to use fresh oregano, the roll of thumb is 1 teaspoon of dried herbs equals 3 teaspoons of fresh herbs. So you will need to use 3 times amount of fresh oregano if you want to substitute that for the dried in this recipe.
How to make slow cooker Greek lamb.
Step 1: First thing you want to do is stud the piece of meat with garlic. Take a sharp knife and cut little slits all over the roast and stuff them with thin slices of garlic. There are 5 cloves of garlic in this recipe so you need a lot of cuts.
Step 2: Then mix your spices together in a bowl and rub them all over the meat. Use all of the spices and get into the nooks and crannies.
Step 3: Place the lamb leg into the crock of the slow cooker. I like to cook this on low all day (6-8 hours) but you could also cook it on high for less time if you want.
Cooking time may vary due to the size of your roast and because everyone’s slow cooker is different. However you’ll know this is done when it’s fork tender.
I don’t worry about the internal temperature of the meat for this recipe because you want the meat to be fall apart tender and therefore it will be definitely be cooked through.
If you want to get the crispy crusty parts on the lamb.
I love tasty crusty parts on meat and to do that you have to add another step. Half way through the cooking process, try to pour as much liquid out as you can.
Reserve the cooking juices for later if you feel it is too dry or if you want to make gravy. This way of roasting will help the meat to brown and develop that crusty part that tastes soooo good.
If you don’t like those crispy parts no need to pour off the liquid. I personally love that part of any roast.

How we like to eat his Greek lamb roast.
Now it’s time to eat this delicious, tender lamb. You can eat this meat 3 different ways and make many meals out of it.
- Serve it as a main meat dish for a family dinner along with a few side dishes like these low carb green beans. If you aren’t low carb you can roast some yellow onion, potatoes and carrots or add a nice green leafy salad for the perfect meal.
- Or you can also make a gyro flavored salad as pictured below. I made some creamy feta cheese dressing (recipe to come) to go with the Greek salad pictured below and topped my salad with it to make a gyro salad. It was awesome.
3. Lastly you can also make a gyro if you don’t care about carbs. Grab some naan or pita bread and drop some shredded lamb on it along with your favorite gyro toppings. I personally prefer naan bread and sometimes I can find mini Nannie’s bread at Costco which work perfectly.
If you are looking for a low carb tzatziki sauce.
If you decide to eat this dish as is or in a gyro, you might want have some homemade tzatziki sauce. That is the sauce or topping you usually get when you buy a gyro and it goes great with lamb and you can whip it up in minutes.
This Greek recipe is usually made with yogurt, cucumbers, garlic and extra virgin olive oil. Sometimes people put herbs such as dill, mint, parsley in it. Two of my low carb friends have a yummy low carb tzatziki sauce on their blogs that you should check out:
- Annissa from Simply so Healthy’s Tzatziki Sauce
- Maya from Wholesome Yum’s Easy Greek Tzatziki Sauce
If you want to make a salad dressing for a gyro salad, I would suggest making a simple red wine vinegar (or fresh lemon juice) and extra virgin olive oil dressing. Season with salt, black peppers and oregano and even a little fresh garlic.
You could also play around with the tzatziki sauce to make it more of a creamy salad dressing.
Well I hope you give this slow cooker Greek-style lamb recipe a try. It was an amazing dinner to me and brought back memories of my grandma’s delicious cooking. I can’t wait to make it again.

Bob R says
I made this today and was really pleased with the outcome. I didn’t use it for a gyro or a salad….instead I tossed in some turnips and carrots in the last couple of hours and sliced up the lamb amd served it with the veggies amd some English mustard on the side. Yummy! Thanks for this great, simple recipe!!
Denise says
Hi Bob, I’m so glad you liked it. I’ll have to try it with the added veggies next time.
Amanda says
Hi! I have a 1.78 lb boneless lamb sirloin–would this work for this recipe?
Denise says
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!
JUNE D’Andrea says
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 says
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. 😉
MJ says
Hi there,
Does this freeze and reheat well? just wondering as I’m looking to use this to add to my meal prep rotation over the next few weeks.
Thank you!
Denise says
Hi MJ, I freeze a lot of things but I’ve never tried cooked lamb. From what I’ve looked up online people do it. I’m not sure the flavor comes through the same because I haven’t done it. Sorry I’m not more help but I think you can.
