Step-by-Step Instructions on How to Make Sausage and Potato Casserole

Step 1 – 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.

Step 2 – 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.

Step 3 – Preparing the Mixture. Once the sausage is browned, it’s time to prepare the mixture that will give your casserole its creamy, flavorful goodness.

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. This mixture will infuse the potatoes with a savory and creamy flavor!

Step 4 – 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.

Next, layer half of the sausage mixture over the potatoes, spreading it evenly.

To add richness and a cheesy delight, sprinkle 4 ounces of shredded cheddar cheese over the sausage mixture.

Repeat the layering process – potatoes, sausage mixture, and cheese. The final layer should be the remaining cheese, creating a golden and melty top layer once baked.

Step 5 – Baking the Casserole. Once the layering is complete, cover the baking dish with aluminum foil to ensure even cooking and prevent the top from burning.

Place the dish in the preheated oven and bake for about 60 minutes. The casserole is ready when the potatoes are soft and the flavors have melded together into a harmonious symphony of taste!

Step 6 – 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.

Once cooled, dish out hearty portions and enjoy the creamy, savory goodness of your homemade Sausage and Potato Casserole!

Storing and Reheating Sausage and Potato Casserole

A good casserole can be enjoyed for days if the leftovers are stored and reheated properly. Here’s how you can relish the flavors without compromising the quality!


  1. Cooling: Before storing, allow the casserole to cool to room temperature to prevent condensation, which can make the dish soggy.
  2. Dividing: If you have a large amount left, consider dividing it into smaller portions for quicker reheating and to preserve freshness.
  3. Container: Transfer the casserole into airtight containers or wrap the baking dish tightly with aluminum foil or plastic wrap to avoid contamination and drying out.
  4. Refrigeration: Store the casserole in the refrigerator if you plan to eat it within 2-3 days.
  5. Freezing: For longer storage, consider freezing the casserole. Make sure it’s sealed tightly to avoid freezer burn. It can be stored in the freezer for up to 2-3 months.


  1. Thawing (if frozen): If the casserole has been frozen, allow it to thaw overnight in the refrigerator before reheating for the best results.
  2. Oven Reheating: Preheat the oven to 350°F (180°C). If reheating in a baking dish, cover it with aluminum foil to retain moisture. Place the dish in the oven and heat for about 20-30 minutes or until the casserole is heated through and the cheese is melty.
  3. Microwave Reheating: If you’re short on time, you can reheat individual portions in the microwave. Place a portion on a microwave-safe plate, cover it with a microwave-safe lid or plastic wrap, and heat for 2-3 minutes, stirring halfway through to ensure even heating.
  4. Check the Temperature: Ensure that the internal temperature of the casserole reaches at least 165°F (74°C) before consuming.
  5. Serving: Once reheated, give it a good stir, and add any additional seasoning if needed, then serve and enjoy!

By following these storage and reheating tips, you can continue to enjoy the delicious flavors and textures of your Sausage and Potato Casserole without compromising its quality.
