When I first made this on a busy weeknight I was instantly hooked by how simple the steps were and how rewarding that first cheesy bite tasted We now turn to this casserole whenever the craving strikes for something both comforting and satisfying
Ingredients
- Shredded hash browns: The frozen kind keeps things fast and they soak up the creamy flavors Choose a brand with no extra additives for pure potato taste
- Sour cream: Adds tangy richness and helps create a creamy sauce
- Cream of mushroom soup: Binds the casserole together and brings depth Look for one with a chunky texture and balanced flavor
- Shredded cheddar cheese: Lots of it Choose sharp cheddar for the best cheesy flavor and meltability Grate your own if you want the freshest melt
- Pepper: Freshly ground gives the best kick
- Salt: Taste your mixture and adjust as you like Use kosher salt for even seasoning
- Smoked sausage: Sliced thick so each bite has a hearty chew Go for a good quality smoked sausage with visible specks of black pepper for extra flavor
Step-by-Step Instructions
- Prepare the Hash Browns:
- Pour the bag of shredded hash browns into a large mixing bowl Make sure the pieces are separated and not frozen together Break up any clumps using a table knife if needed
- Mix the Creamy Base:
- Add sour cream and cream of mushroom soup into the bowl Sprinkle in the pepper and a little bit of salt Stir this mixture very well so every potato shred is evenly coated with the creamy sauce
- Add Cheese and Combine:
- Pour in two cups of the shredded cheddar cheese Reserve the last cup for topping Stir gently until the cheese is fully scattered through the potatoes and nothing is dry
- Bake the Base:
- Lightly grease a 9 by 13 baking pan Spread the entire mixture in an even layer across the pan Place in a 350 degree Fahrenheit oven and bake for 35 minutes until the edges begin to bubble and the top takes on a pale golden hue
- Top with Smoked Sausage and Cheese:
- After the first bake pull the pan out Sprinkle the remaining cup of cheddar cheese over the top Arrange the sliced smoked sausage on top in an even layer Return the pan to the oven and continue baking for 15 to 20 minutes until the sausage is browned at the edges the cheese on top is fully melted and everything is piping hot

My favorite part is the way the sausage crisps up on top during the second bake It reminds me of Sunday dinners at my grandma’s house where everyone would battle over the pieces with the most cheese and sausage baked on
