Preparation and Preheating. Begin by preheating your oven to 400 degrees F to ensure it reaches the appropriate temperature by the time you’re ready to bake.
Cook Sausage. In a large skillet, cook the pork sausage over medium heat. The sausage should be browned and cooked through, which should take approximately 6-7 minutes. Crumble the sausage as it cooks to ensure even browning.
Preparing the Mixture.Combine the cooked sausage, condensed cream of mushroom soup, milk, chopped onion, salt, pepper, and Worcestershire sauce in a large mixing bowl. Stir all the ingredients until they are well combined.
Layering the Casserole. Start the layering process by placing half of the frozen diced potatoes at the bottom of the prepared baking dish. Spread them out evenly to cover the base.
Cooling and Serving. After baking, remove the casserole from the oven and let it cool for about 15 minutes. This resting time allows the flavors to settle and the casserole to firm up a bit, making serving easier.
CROCKPOT VERSION The crockpot version of the Sausage and Potato Casserole is a popular dinner option for families. It offers convenience and requires minimal effort. Simply follow the recipe and layer the ingredients in the slow cooker rather than a baking dish. Cook on low for 4-6 hours or on high for 2-3 hours until the potatoes are tender. This allows you to attend to other tasks while the casserole cooks to perfection. The result is a deliciously comforting dish that will please everyone at the table.
