This slow-cooked lamb is cooked to a fork-tender in a tomato and caramelized onion-based gravy with spices like cumin, paprika, and cinnamon. Today, I served it over a bed of creamy Parmesan polenta, and yet, mashed potatoes, and steamed rice would also be perfect.

Do you love lamb? We love beef and lamb very much. Lamb recipes are by far the most favorite in our home. My Rhea gives me heartache. Because though she eats, she eats so little that she is always underweight. The one thing she does love is meat. So, recently, we've been more slow-cooked recipes at home.
Why make this lamb
- Well, meat with creamy mashed corn means this lamb with creamy polenta. Whether you make it in the slow cooker or on the stovetop, this meat cooks fork tender and melts in the mouth.
- The list of ingredients sounds like a lot, but they are not that difficult to source. If you often cook then you probably already have it in your pantry.
- Do you see that rich color? That comes not just from the tomatoes, but from the combination of caramelized onions and tomatoes. It also adds a unique sweetness to the lamb along with the flavor of all the other exotic spices we have to hear.
- The secret to making this dish even more flavorful. Do you know what happens to onions when you cook them until golden? They become brown, and sweet too. The sweetness enhances the meat, and the brown deepens the color of the red sauce, which creates magic when it comes to flavor.
- I have given you both the stovetop and slow cooker or crockpot method, so you use whichever works in your favor. For years, I've made this on the stovetop before I bought my slow cooker. The slow cooker works great when you don't have time and want a secure method.

Ingredients and substitutes
- Lamb - As I said above, I usually prefer to use a shoulder or leg for my slow cooking, but you also get low cuts that are much cheaper. If you ask your butcher to recommend what's the best he has with him for the day, I'm sure he will be happy to suggest it.
- Polenta - These are very readily available in most supermarkets nowadays. They come in yellow-colored bags and are also called yellow cornmeal. Please note that cornflour and cornmeal are not the same. Cornmeal is coarse and thicker than semolina.
- Red onions - Are sweeter than the regular brown or white so do look for a milder variety. Plus we cook them down for 10 minutes until almost caramelized. This adds sweetness and intense flavor to this dish.
- Dried herbs - I prefer to use the dried herbs in these recipes, so I don't have to fish out too many things later. Since it's cooked long and slow, the dried herbs do get enough time to work their magic. Of course, you are welcome to use fresh anytime.
- Canned Tomatoes - I do prefer canned tomatoes. They are thicker in consistency and have better color, so the result is a thicker and prettier sauce. Having said that, of course, if you prefer fresh that would work too. A good 2 cups of chopped tomatoes would be a good substitute. The result will differ in texture and taste, but still delicious.

Slow-cooked lamb with polenta
Stovetop
- Season the lamb pieces with Salt and pepper. Coat well in flour and dust off excess. Set aside
Pro tip - Using a sturdy cutting board and chef's knife cut lamb into bitesize pieces not too small. - Add 2 tablespoon olive oil to a cast-iron skillet or heavy-bottom saute pan and brown the meat on all sides for 3 to 5 minutes.

Slow-cooker / Crockpot

Creamy polenta
- In a deep saute pan boil the water with salt and pepper. Lower the heat to medium so it's not a rolling boil
- Use a wooden spoon and stir the water creating a gentle swirl. Keep stirring and adding the polenta in a gentle stream (this will avoid lumps)
- Once all the polenta is in lower the heat to an absolute simmer. Cover and let cook for 45 minutes stirring well every 10 minutes.
- When cooked it will be thick and creamy. Add the butter and Parmesan - stir it in well. Cover and let sit for 10 minutes before you serve.
Pro tip - Polenta thickens further after cooking so don't worry if it appears looser than as shown in the images below. - Polenta thickens further after cooking so don't worry if it appears looser than as shown in the images below.

Tips for success
- I cut the lamb into 2-inch cubes but you can make big pieces and cook a bit longer.
- Thaw the lamb at least an hour before you cook it. Room temperature meat will not seize at high temperatures.
- This recipe will work with 4 to 6 lamb shanks as well.
- Searing the meat must be done on medium-high heat so you get a nice crisp coating that keeps all those juices inside.
- I am using canned crushed tomatoes but you can use 2 cups of fresh finely chopped tomatoes as well.
- In this recipe, you can use lemon juice, balsamic, or apple cider vinegar.
- This braised lamb is more delicious the next day so make it up to two days ahead and keep it in the fridge.

Frequently asked questions
If stored properly this slow-cooked lamb will last in the fridge for 3 to 4 in the refrigerator.
Usually, we use cuts that come from muscles that work hard in the animal such as lamb shoulder, leg of lamb, and lamb shank. These cuts benefit from the long and slow cooking and also absorb lots of flavor in that time. As you can see most of the lamb recipes, I shared with you are slow-cooked, not necessarily in the slow cooker and I usually use lamb shoulder or leg of lamb even when I cut it to bite-size pieces like this one
If you don't' fancy polenta, you can try a side of potatoes like mashed potatoes, lemon rosemary roast potatoes, lemon dill potatoes, potato wedges. Rice pilafs and pilaus are perfect with slow-cooked meats such as quick vegetable pilaf or fragrant rice with fruit and nuts. If you looking for a low-carb alternative try cauliflower rice.
Almost any vegetable works great on the side. Try
quick garlic sesame asparagus or garlic Parmesan asparagus, Swiss chard patties, sesame green beans, oven-baked butternut squash, oven-baked carrot sticks

You can't beat slow-cooked lamb! So full of flavor and tender. Our whole family enjoys it any way they can get it. And serving it over polenta a la Italian style has my mouth watering. I'll be making this recipe VERY soon.
