Loaded with hash brown potatoes, cheese, sour cream, onion, and kielbasa, this smoked sausage casserole is a hearty, comforting meal with just 10 minutes of prep!

A Few Notes Before You Get Started
- This recipe comes from a blog reader named Diana, who calls it “Country Comfort Casserole.” I can’t think of a better name for the cozy dish! Best of all, the dump-and-bake meal requires almost no prep work — just stir everything together and pop it in the oven.
- You can offer the versatile dish for a meat-and-potatoes dinner on busy weeknights, or for a hearty breakfast casserole without any eggs.
- Find your largest bowl for mixing the ingredients!
- Dice the onion into very small pieces so that it softens and becomes tender while the casserole bakes. For an even easier option, use about 1 ½ cups of frozen pre-diced onion that you thaw and pat dry. No chopping necessary, and it’s already nice and soft when it goes into the casserole!
- When possible, use a block of sharp cheddar cheese that you grate by hand, rather than a package of pre-shredded cheese. The hand-grated variety melts smoother into the casserole.
- Allow the sour cream to come to room temperature. Very cold sour cream has a tendency to curdle or separate when heated quickly.
Serving Suggestions
We typically enjoy this sausage and potato casserole for a quick weeknight dinner; however, it’s also an easy breakfast or brunch option (even without eggs). Pair it with a crisp green salad dressed in pepper jelly vinaigrette, with old-fashioned applesauce, or alongside braised red cabbage, spinach salad with bacon, brown sugar glazed carrots, or roasted broccoli.
Preparation and Storage Tips
- This sausage casserole is perfect for entertaining because you can prepare it in advance. Assemble the dish up to 24 hours ahead of time, keep it covered in the refrigerator, and then bake according to the recipe instructions. Allow the dish to sit on the counter and come to room temperature while the oven preheats.
- Leftovers will keep in the refrigerator for 3-4 days.
- I do not recommend freezing this dish, as sour cream and other dairy-based ingredients tend to separate or “break” when thawed.

Smoked Sausage Casserole
Prep: 10 minutes
Cook: 40 minutes
Total: 50 minutes
A comforting casserole that includes hash browns, cheese, sour cream, onion, and smoked sausage!
Ingredients
- 1 (30 ounce) package frozen shredded hash brown potatoes, thawed (about 12 ½ cups total)
- 1 (14 ounce) package fully-cooked smoked sausage (such as Hillshire Farm Polska Kielbasa)
- 1 ½ cups grated sharp cheddar cheese (about 6 ounces total)
- 1 cup (8 ounces) sour cream, at room temperature
- 1 medium onion, very finely diced
- ¼ cup (half of a stick) butter, melted
- ¼ teaspoon ground black pepper
- ¼ teaspoon kosher salt
- 1 (10.5 ounce) can condensed cream of chicken soup
- Optional garnish: sliced green onion or chopped fresh herbs such as parsley, chives, basil, or thyme
Instructions
- Preheat oven to 350°F (180°C). Grease a 13 x 9-inch baking dish and set aside. Cut sausage into slices, and then into quarters (so that you have small bite-sized pieces). In a large mixing bowl, stir together all of the ingredients until completely combined.
- Transfer the mixture to the prepared baking dish.
- Bake, uncovered, for about 40 minutes (or until hot, bubbly, and lightly browned on top).

Smoked Sausage Casserole Recipe Variations

You make the best dump and bake meals! Love how easy this is to make with those simple ingredients. Sounds like this would be perfect for breakfast or dinner! Yum!
Thanks, Gayle! That’s exactly right — it’s perfect for any time of day!
Hey there,
Thank you so much for this easy recipe! My boys love it even I do personally, reminds us of Potato scallops as I cut the potatoes diagonally for this recipe. It was awesome! Thanks again. Hope there’s more other recipes like this!
Wonderful! I’m so glad that your family approves! 🙂
Delicious recipe! My hubby and 2 year old loved it! Definitely making this again. I love your blog and recipes!
Thank you so much, Tiffany!
I made this and it was really delicious and then thought it would be more delicious with bacon, I’m going to try that next time.
Thanks, Patricia! You can never go wrong with bacon! 🙂
Thank you so much Blair for sharing this delicious recipe that our family has been enjoying for years. I hope that all of your followers enjoy it as well.
Thank YOU, Diana, for sharing! 🙂
Easy recipes are my favorite! Holidays are all about chilling and having a good time. We can’t spend all day in the kitchen! haha. This is a great idea for sure!. Thank you for sharing. Happy Holidays!
I agree! Thanks, Paul!
Ooooh, this would be a HUGE hit in our house! I’m going to have to try it whilst we have this random cold snap happening in what should be a hot summer!
Yes!!! I hope that you’ll give it a try! 🙂
I made this super-easy casserole for Christmas brunch yesterday . It was delicious and a big hit with my family… definetly a keeper ! I made fresh Pillsbury Country Biscuits to have with it…a great combination ! I made a little “potato pancake” in the frying pan along side my fried egg for breakfast with some of the leftovers this morning . Now l can hardly wait til supper time as l’m going to fry what’s left in some butter in a frying pan ! Yum ! I love your recipes…they never disappoint ! Merry belated Christmas , Blair , to your family from mine in a very cold Saskatchewan , Canada , where the temperature was -41°C Christmas morning !! 🙂
That’s great, Cindy! I’m so glad that you enjoyed it! Your leftovers sound delicious, too. Merry Christmas!! I can’t believe how cold it is there! 🙂
Hi Blair,
I’ve only just started using your recipes but being from South Africa I’m struggling with some of the ingredients. What can be substituted for the Polish susage.
Hi, Patricia! It’s great to “meet” you! 🙂
You can substitute any precooked sausage for the Polish kielbasa. Even hotdogs would work!
Reading on your site and wouldn’t cooked ham or leftover ham cut in cubes also work?
Hi, Mary! Yes! Leftover ham would work very well!
Hi Blair,
Thanx, I’m going to try it the weekend.
Great. Enjoy!
Would it be OK to add extra sausage or would that throw the whole recpe out of whack?
Hi, Laura! Sure — go ahead and add more sausage! The casserole will still be great! 🙂
Thanks so much for all your help! I found your site this morning through a link on Kath Eats and I’m already obsessed. I printed two of your dump and bake recipes and I’m so excited to make them for my family this week. 🙂
That’s awesome! I’m glad to “meet” you, Laura! 🙂 Kath was so kind to share my Brunswick Stew last week!
Enjoy the easy recipes, and thanks again for stopping by!
Hey, Stephanie! Thanks so much for your note! The soup is NOT supposed to be diluted, so that explains why yours was a bit wet. Thanks for the heads-up — I just updated the recipes to specifically clarify the undiluted soup. 🙂
Hi! I could only find frozen hash brown patties at the small grocery store I shopped at this week. The package says to keep them frozen until you cook them…do you think I can layer them on the bottom and put the rest of the ingredients mixed together on top? Thanks!
Hi, Laura Beth! Yes, I think it would work to just layer them on the bottom. It would be like a “hash brown crust.” 🙂
Another option that you could try would be to cut up/dice the hash brown patties into bite-sized pieces. Stir those together with the rest of the ingredients, just like you would the other shredded hash brown potatoes. Either option should do well!
If it were me, I would thaw the patties in the refrigerator before using them in the casserole. That might not be optimal according to the package instructions, but the package assumes that you’re going to prepare them as individual patties (rather than including them in a casserole). You don’t have to thaw them first, but it would make the baking time shorter and you wouldn’t risk overcooking the rest of the ingredients while you wait for the potatoes to heat through.
Hi Blair,
I usually add frozen peas to this recipe to add a little color and veggie!
Sounds like a great addition, Dona! Thanks for that suggestion! 🙂
This sounds sooo good and such a great way to use up leftovers too!
Ooooh, this would be a HUGE hit in our house! I’m going to have to try it whilst we have this random cold snap happening in what should be a hot summer!
Was so nice to cook an easy meal after cooking constantly through the Holidays. I actually lived in my apron. This sausage casserole was outstanding and super easy to make. Thanks for the reprieve.
Thanks, Debbie! I’m so happy to hear that you enjoyed the recipe, and thank you for taking the time to leave me a note.
I made this recipe last night and it was very good. Even my picky eater liked it. I used parchment paper in the bottom of the pan so had no problem with sticking. I followed the recipe exactly except for no added salt. The sausage, cheese and chicken soup all have lots of sodium so figured it did not need any more. I was right. I cooked it for 40 minutes at 350 in a convection oven and it did not look done enough so I added 10 more minutes. Next time I may add 20 minutes. My only issue with this recipe is #1 finding a bowl big enough for everything and #2 it was a real effort to try and stir that much volume of ingredients. I think when I make it again I will layer things in the pan much as one would make lasagna. This was really very good! I even had a little extra taste at bedtime which I rarely do. Thanks for making this recipe available.
Thank you! Glad that it was a hit! 🙂
I made this for our dinner tonight and it was delicious! Easy to make and yummy…. good comfort food. We both loved it! 🙂 Thanks for another great recipe Blair. 🙂
Oh, good! I’m so glad that you enjoyed it, Tess. Thanks for letting me know! 🙂
Has intone tried adding eggs to this recipe?
Hi, Kami! I haven’t tried eggs with this particular recipe, but here is a similar recipe that uses the eggs, hash browns, and cheese. You can add smoked sausage instead of hte breakfast sausage if you like! https://www.theseasonedmom.com/bacon-cheese-hash-brown-breakfast-casserole/
This was a hit with my family, does this freeze well?
Hi, Paula! I haven’t tried freezing it, but I would be concerned that the dairy-based sour cream in the mixture may separate or break when thawed. Also, potatoes tend to have a grainy, mushier texture when thawed. It wouldn’t be my first choice, but you can certainly feel free to experiment if you’re feeling brave. 🙂
This was awesome!! Thank you for the recipe. So easy to make!! Highly recommend!!
Thank you, Nancy!
Hi, Blair! I’m sure this recipe is delicious as is but I was wondering which of the ingredients I could cut back upon. I get it that I need the quantity of hash browns but then a near pound of sausage, one and and a half cups of cheese, half a stick of butter and a cup of sour cream! I’m concerned partially about it being too rich for me and, honestly, the price. I was at the grocery today and I was just sick about the prices. My calculations are that the casserole would cost at least 10 dollars, maybe to 15 and that’s just too much for a casserole on my budget. Could I cut back to, say, half of the sausage and the cheese? Thanks!
Hi, Marion! Yes, ma’am — that should work just fine to cut the sausage and cheese in half. 🙂
