Ingredients for a sausage casserole
- Sausage – Ground breakfast sausage, this adds all the flavor, so use the best quality you can find.
- Potatoes – Russet potatoes work best for this recipe but Yukon gold potatoes or red potatoes will also work. The texture will be a little different and the cooking time can vary if using a softer potato.
- Onion – A sweet onion, like a Vidalia, works best for breakfast casseroles, they are not as pungent as a yellow onion.
- Cheese – Freshly grated cheddar cheese will make such a difference. Try not to use pre-shredded cheese if you can help it! A sharp cheddar or colby jack work great for this recipe.
- Worcestershire sauce – this amazing ingredient adds so much flavor to whatever you add it to and it gives the sauce a burst of flavor.
- Pantry items – butter, flour and milk.
How to make a breakfast sausage and potato casserole
Step 1: Cook sausage
Cook the sausage and then drain on a paper towel lined plate.
Step 2: Make the sauce
Cook the onions first, then make a simple sauce with flour, butter and milk, adding Worcestershire for flavor, then add a little cheese.
Step 3: Assemble
Add a layer of sliced potatoes, sausage and sauce to the casserole dish and repeat with a second layer.
Step 4: Bake!
Bake covered for roughly an hour. Remove the tin foil and top with cheese and bake for a few more minutes uncovered for a golden brown cheesy top.
Pro tip: Grate your own cheese! It’s a little more work than buying pre-shredded cheese, but it’s totally worth it. Freshly grated cheese melts better and has much more flavor.

Barbara’s Tips + Notes
- Warm the milk in the microwave for a few seconds before adding to the sauce. This will save some time.
- You can prep this the night before and cover with plastic wrap. Let it come to room temperature before baking.
- Russet potatoes work best for this type of potato casserole, they will keep their shape without getting mushy. If using another type of potatoes, check the cooking time, it may not take as long for them to cook through.
