Sausage & Polenta Casserole

Jump to Recipe

Polenta is not frequently used in casseroles – and I have absolutely no idea why. It is such a nice change from pasta or rice casseroles. You get a different texture and flavor that your family is going to adore. Sausage & Polenta Casserole is a simple weeknight meal, that is very quick to put together.

I used ready made polenta – which comes in a tube (looks like breakfast sausage) and is usually found in the produce section. You can also swap out for instant polenta, adding in the same chicken broth, heavy cream and mozzarella. Fun fact – grits and polenta are essentially the same thing, in terms of how it created. The only real difference is the type of corn that is used. Polenta is typically made from yellow corn, while grits are usually made from white corn. If you can’t find polenta in your grocery, you could swap out for grits. But I would add some salt by way of parmesan cheese.

This is a very filling casserole, so you probably won’t need a side dish. Especially since you have your meats, cheese, veggies and starch all in one. But you could always add in some steamed broccoli, a Caesar salad or some garlic bread.
