Recipe: Onion-Topped Sausage 'n' Mashed Potato Casserole

This hearty Onion-Topped Sausage ’n’ Mashed Potato Casserole features a rich, meaty tomato sauce, and time-saving refrigerated mashed potatoes. You can almost think of this as a version of a traditional shepherd’s pie given the layer of potatoes spread over the sausage. The flavor of the sweet turkey sausage is the true foundation of this delicious dish, but you can substitute chicken sausage if you prefer. Everyone will really love the crunchy fried onions that are layered on top though—that is the true star of this recipe. That step is definitely kid-approved. It will be hard to wait before digging in, but we recommend letting this casserole set up five minutes after it comes out of the oven before serving it. We hope you can wait.
