This smoked sausage cheesy potato casserole is pure comfort food—ideal for busy weeknights or chilly weekends when you crave something simple and satisfying. Every bite wraps you in creamy potatoes and gooey cheddar, with smoky sausage adding that just-right hearty touch.
I whipped this up on a hectic weeknight with nothing but a bag of hash browns and smoked sausage on hand and it instantly became a staple my family requests whenever they are in need of a little homey comfort.
Ingredients
- Shredded hash browns: perfect for a fluffy yet creamy base look for a bag where the potatoes are not freezer burned or clumped together
- Sour cream: adds tang and creaminess the full fat variety delivers the silkiest result
- Cream of mushroom soup: builds richness and a savory note use a classic brand or go for a low sodium version if you prefer
- Shredded cheddar cheese: brings stretchy melty comfort sharp cheddar reins in the best flavor so try to buy freshly shredded cheese from the block
- Salt and pepper: seasons and balances the creamy filling a pinch of salt is optional if your sausage is quite salty
- Smoked sausage: sliced into coins for smoky robust flavor look for ones with a speckled appearance and a rich aroma
Instructions
- Prep the Potatoes:
- Pour the full bag of shredded hash browns into a large mixing bowl break up any clumps so the potatoes are light and even for mixing
- Combine Wet Ingredients:
- Dollop in the sour cream and cream of mushroom soup scatter the salt and pepper over the potatoes Use a large spoon to fold everything together fully coating the potatoes so every bite is creamy
- Mix in Cheese:
- Sprinkle in two cups of the shredded cheddar cheese and stir again making sure the cheese is evenly woven throughout the mixture
- Spread in Baking Dish:
- Lightly grease a 9x13 baking dish with butter or nonstick spray spoon in the potato mixture and spread it out to reach all corners creating an even layer
- Initial Bake:
- Place the dish on the middle rack of a preheated 350 degree oven Bake for 35 minutes so the potatoes soften and the flavors meld together
- Add Toppings:
- Carefully remove the dish and top it with the remaining cup of shredded cheddar cheese Scatter the sliced smoked sausage across the top arranging for even coverage
- Final Bake:
- Return the dish to the oven and bake for 15 to 20 more minutes Wait until the casserole is bubbling hot and the cheese topping is fully melted Slice into squares and serve hot

My favorite part is always the bubbly cheese that browns at the edge of the pan—it never fails to spark a childhood memory of scraping the last cheesy bits from my mom’s baking dish with a fork. Smoked sausage truly shines here as it delivers both flavor and nostalgia in every bite.
