How to Make Sausage Green Bean Potato Casserole Recipe
Step 1: Preheat and Prep
Preheat your oven to 400°F and spray a 9×13″ baking dish with non-stick spray.
Step 2: Potato Seasoning Party
Toss your halved baby potatoes in a big zip-top bag with vegetable oil, Slap Ya Mama seasoning, black pepper, and red pepper flakes. Seal and shake like your dinner depends on it (because it kind of does).
Step 3: Brown the Sausage
In a skillet over medium-high heat, add sausage and ¼ cup water. Cook until browned and the water’s mostly gone. Set it aside to cool, then toss it into the potato bag.
Step 4: Sauté Your Way to Flavor
Melt butter in the same pan, add onions and garlic, and sauté until the house smells amazing and the onions are translucent. Let that cool a bit, then toss it into the bag, too.
Step 5: Shake It All Together
Now add those drained green beans to the mix. Seal and shake again to marry all the flavors.
Step 6: Bake It Up
Pour everything into your greased baking dish, cover with foil, and bake for 40 minutes, or until your potatoes are tender and your kitchen smells like Sunday dinner.

Description
Cozy up with this hearty Sausage Green Bean Potato Casserole—made with smoky kielbasa, tender baby potatoes, and crisp green beans, all tossed in savory spices and baked to golden perfection. It’s the kind of comforting family dinner that brings everyone back to the table.
Ingredients
- 1½ pounds Kielbasa or smoked sausage sliced into ¼-inch pieces
- 2 pounds baby creamer potatoes thoroughly washed and halved
- Two 15-ounce cans of green beans drained
- ⅛ cup of vegetable oil
- ¼ cup of butter
- 1 cup of onions finely chopped
- 3 cloves of garlic minced
- 1 teaspoon of Slap Ya Mama seasoning
- 1 teaspoon of garlic powder
- 1 teaspoon of black pepper
- ½ teaspoon of red pepper flakes
- ¼ cup of water
Instructions
Begin by preheating the oven to 400°F (204°C). Prepare a 9×13 inch baking dish by coating it evenly with non-stick cooking spray.
- Proceed to wash the baby creamer potatoes thoroughly. Once cleaned, slice each potato in half and place them into a sealable gallon-sized bag.
- Add the vegetable oil, Slap Ya Mama® seasoning, black pepper, and red pepper flakes to the bag containing the potatoes. Seal the bag securely and shake vigorously to ensure an even coating of the seasoning on the potatoes.
- In a large frying pan, place the sliced sausage and add ¼ cup of water. Cook over medium-high heat. Continue cooking until the sausages have achieved a browned exterior and most of the water has evaporated.
- Once the sausage is cooked and has cooled down sufficiently, add it to the bag with the seasoned potatoes.
- Using the same frying pan, melt the butter. Add the chopped onions and minced garlic to the pan. Sauté until the onions become translucent and fragrant.
- Allow the onion and garlic mixture to cool for a few minutes. Once it has cooled to a manageable temperature, add it to the bag containing the potatoes and sausage. Seal the bag and shake well to combine all the ingredients.
The final step before baking involves adding the drained green beans to the bag. Once again, seal the bag and shake to ensure a thorough mix of all ingredients.
- Transfer the contents of the bag into the prepared baking dish. Cover the dish with aluminum foil.
- Place the covered dish in the preheated oven. Bake for 40 minutes, or until the potatoes are tender.
- Once cooking is complete, carefully remove the baking dish from the oven. The Sausage Green Bean Potato Casserole is now ready to be served.
Notes
Don’t skip the bag shaking! It really helps coat everything evenly.
