- Begin by preheating the oven to 400°F (204°C). Prepare a 9x13 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.
