Slow Cooker Lamb Shanks With Sweet Potato Polenta

Although I never thought of myself as someone who would enjoy using a slow cooker, since I bought mine a year ago I have completely fallen in love with it. When I know I will have a busy day coming up, I try and plan a slow cooker meal that I can assemble in the morning, turn on, and have ready by dinner.

Shanks of any variety, whether they are lamb, veal, or pork are great cooked in a slow cooker as this type of meat lends itself perfectly to slow braising. After 6 hours in the slow cooker, the meat literally falls right off the bone.

Although you could add carrots, mushrooms or celery to this dish, I decided to keep it simple, and chose to use just fennel and onions instead. To serve my dish, I made a pot of quick cooking polenta flavored with sweet potatoes and which complimented the rich flavors of the shanks perfectly.

When serving rich, braised meats, a topping that is made from combining parsley, lemon zest, and garlic called gremolata really brings the flavors of this dish together.

Buon Appetito!

  1. Over Easter weekend, the idea of roasting lamb was brought up. Unfortunately, due to timing we weren’t able to get one, but the thought is still exciting to me. Since I’ve never bought lamb before, can you give me any tips on what to look for?

  2. MMMMMMMM! I’m going to make this next week! Other than a tomato and onion salad can anyone recommend a side, salad or dessert pairing?

    Lately I’ve realized how lacking I am in experience on how to combine dishes to create a complete and satisfying meal. I read that with a fatty meal you want something to cut the fat or brighten the palette thus the tomato salad? Why am I thinking fig. Wishing I had a fig tree…..
