Ingredients and Preparation
Here are the key ingredients that make this Sausage Green Bean Potato Casserole both flavorful and satisfying:
- Sausage Kielbasa: The sausage brings a smoky richness to the dish. If kielbasa is not available, any smoked sausage or even chicken sausage can be used as an alternative.
- Baby Creamer Potatoes: These small, tender potatoes have a creamy texture when cooked. They absorb flavors well and are perfect for casseroles. If you can’t find creamers, small red potatoes will work just fine.
- Green Beans: Fresh green beans are ideal, but frozen or canned green beans can be used as alternatives. They add a nice crunch and some freshness to balance out the heaviness of the sausage and potatoes.
- Oil and Butter: A combination of oil for tossing the potatoes and butter for sautéing the onions and garlic helps to infuse the dish with flavor while ensuring everything cooks evenly.
- Onions and Garlic: These aromatics form the flavor base for the casserole. They sauté to create a savory, fragrant aroma that fills your kitchen and enhances the overall taste of the dish.
- Seasonings: Slap Ya Mama seasoning adds a Cajun flair with a touch of heat, while garlic powder, black pepper, and red pepper flakes round out the spice profile.
- Water: Adding water to the sausage while cooking helps to steam it, ensuring it stays juicy and flavorful while it browns.
Step-by-Step Instructions
Step 1: Preheat your oven to 400°F and spray a 9×13 baking dish with non-stick spray to prevent sticking.
Step 2: Wash the baby creamer potatoes and cut them in half. Add the potatoes to a sealable gallon-size bag. Pour in some oil and season with the garlic powder, black pepper, and red pepper flakes. Shake the bag to coat the potatoes evenly with the oil and spices.
Step 3: In a large frying pan, cook the sausage slices with a bit of water over medium-high heat until browned and the water evaporates. This should take about 20-30 minutes. Once done, remove the sausage from the pan and let it cool slightly before adding it to the bag of potatoes.
Step 4: Melt butter in the same frying pan and sauté the chopped onions and garlic until the onions become translucent, about 4-5 minutes. Let this mixture cool briefly before adding it to the bag.
Step 5: Finally, add the green beans to the bag. Give everything a good shake to mix all the ingredients together.
Step 6: Empty the contents of the bag into the prepared baking dish. Cover the dish with aluminum foil and place it in the oven. Bake for 40 minutes or until the potatoes are tender.
Step 7: Once done, remove from the oven, let it cool for a couple of minutes, and serve!

Beginner Tips and Notes
- What if the vegetables overcook? If you find that your veggies are getting too soft, you can lower the oven temperature slightly or reduce the cooking time. It’s always better to check a few minutes before the suggested time to ensure they stay tender-crisp.
- Substituting ingredients: If you can’t find kielbasa, try using any smoked sausage or even chicken sausage for a lighter version. You can also substitute regular potatoes for the baby creamer potatoes if necessary.
- Efficient prep tip: To save time, wash and chop your potatoes and green beans in advance. You can also prep the sausage and seasoning mixture a day before cooking.
Serving Suggestions
This Sausage Green Bean Potato Casserole is hearty enough to be served on its own, but it pairs wonderfully with a side salad or some crusty bread to help soak up any extra flavors. If you want to elevate the meal, try serving it with a tangy sauce or a dollop of sour cream on top.
For leftovers, store the casserole in an airtight container in the fridge for up to 3 days. It also reheats well in the oven, so you can enjoy this easy sheet pan dinner for a couple of days!

This Sausage Green Bean Potato Casserole is the ultimate beginner-friendly dish that’s packed with flavor, nutrients, and heartiness.
