This simple and easy-to-fix, sausage green bean potato casserole has all of my favorite ingredients in one delicious baking dish! This is my kind of cooking!! Great, flavorful, easy-to-find ingredients, easy to put together, delicious results that bring the whole family to the table!
This recipe works well as an entree or a side dish for potlucks, holiday meals, church suppers, and, as I often serve it for BBQs. You can make it on the stovetop, in the oven, or in the crockpot. Both methods work equally well and are convenient for different circumstances and events.
When I’m taking it to a community event or serving it alongside BBQ, I like the stovetop crockpot method best. If it’s being served for dinner, I go the stovetop oven route. Don’t you love recipes that you can tweak to best serve your circumstances?
I hope you’ll try some of my other hearty sausage favorites made with Polska Kielbasa—it’s one of my go-to ingredients for quick, comforting meals. Don’t miss my Black Eyed Pea Soup, Sausage and Bean Soup (a family favorite for over 30 years!), Chicken Tortellini Soup (loaded with sausage, of course!), and my reader-loved One Pan Sausage and Rice. Each one is cozy, flavorful, and sure to be a hit at your table. ♥”
Let’s make this!
Why This Recipe Works
-
One Pan Wonder: Everything bakes together in a single dish, which means easy prep and even easier cleanup.
-
Classic Comfort Combo: Sausage, potatoes, and green beans are a tried-and-true trio that delivers hearty, down-home flavor in every bite.
-
Bold & Balanced Seasoning: The mix of Creole spices with garlic and onion powder adds just the right kick—savory, slightly smoky, and perfectly cozy.
-
Family-Friendly Favorite: Simple ingredients, familiar flavors, and budget-friendly portions make this casserole a recipe you’ll come back to again and again.
Before You Begin
✨ Pick the Right Sausage: Polska Kielbasa brings a smoky, savory punch, but feel free to use andouille or smoked sausage for extra spice.
✨ Fresh Green Beans = Best Flavor: They’ll stay crisp-tender after baking. Frozen beans work in a pinch—just thaw and pat dry before using.
✨ Potato Perfection: Petite gold potatoes hold their shape and get creamy when baked. If using russets or red potatoes, cut them into uniform 1-inch chunks so they cook evenly.
✨ Even Spice Coverage: Sprinkle the seasoning in layers while tossing the veggies to avoid clumps and ensure every bite is well-seasoned.
✨ Check Doneness: Pierce a potato with a fork before pulling the casserole out of the oven—it should be tender but not falling apart.
Sausage Green Bean Potato Casserole Ingredients
- Oil: Use any neutral flavored oil with a high smoke point
- Polska Kielbasa: There are many varieties of Polska Kielbasa. I’ve recently discovered a new brand, no endorsement, just my opinion: Kiolbassa Provision Co. Sausage, Traditional, Pork & Beef, Hickory Smoked. If you can find it, use it! It’s so much better than the sausage from Hillshire Farms, in my humble opinion.
- Potatoes: I use petite gold potatoes. They’re just the right amount of starchy and creamy! You can replace it with Russet potatoes. Just cut them into large 1-1 1/2 inch chunks. Baby creamer potatoes work the same.
- Green Beans: Fresh green beans, trimmed and cut in half.
- Onion: I use a yellow onion, aka Spanish onion. You can also use white onion. I like them sliced but chopped onions work equally well.
- Garlic: Please use fresh garlic, not the pre-minced stuff in a jar. Check out this article from Bon Appétit to see why I NEVER use that stuff!
- Seasoning: I like the brand Tony Chachere’s Creole seasoning or slap ya mama cajun seasoning
- Garlic Powder: To impart a mild garlic flavor.
- Onion Powder: To impart a mild onion flavor.
- Black Pepper + Salt: Because every savory recipe needs it!
Storing + Freezing + Make-Ahead
- How Long Can You Keep This In The Refrigerator? Leftovers can be stored in the fridge for 3-4 days. Store in an airtight container.
- Can You Freeze This? Store it in a Ziploc bag and it can be frozen for up to 6 months!
- Make-Ahead Tips: Chop all the veggies ahead and place them in the fridge.

Made this on a Friday to eat over the weekend it was delicious. I used frozen green beans instead of fresh and I added some zesty shredded cheese on top after it was cooked. I only have one question how long is this dish good for in the refrigerator?
Hi Darren! Leftovers can be stored in the fridge for 3-4 days
Can you use canned green beans?
Hi, Lesley. I prefer using fresh green beans.
I made these and had my daughter over for dinner. As I was putting the leftovers away I asked her if she would like to take some to work tomorrow. She said yes, grabbed the tray and ran out the door.
Hi, Karen! LOL, that’s so cute! She really loved it haha. Thank you so much for your positive feedback 🙂
I’m making this today and am wondering since I am using a homemade salt-free creole seasoning, should I double the salt? Thanks.
Hi, Marianne. Yes, and add the extra salt after baking to taste.
I ended up adding it with the rest of the seasoning (because I made it before you were able to reply) and it turned out just fine. I’m sure I will be making this one again. 👍
Oops! Sorry. I’m glad it went well!
Extraordinary! I made this but basically doubled the recipe and didn’t have enough fresh green beans. I added about a cup of washed and quartered Brussels sprouts to make up for the beans . It was delicious and my family really enjoyed it too. I will add this to my permanent recipes file! Kathleen once again, didn’t disappoint! 🙂
Thank you Tricia, so glad you found another recipe you enjoyed!
