This casserole earns its place in the regular dinner rotation because it combines the main parts of a satisfying meal in one baking dish. The smoked sausage supplies rich, savory flavor, while potatoes make the dish filling and green beans add color and a fresh vegetable bite.
There is no complicated sauce to prepare and no separate skillet of meat to clean. A little butter or olive oil, chicken broth, garlic, and paprika create enough seasoning to make every forkful taste warm and savory.
The covered and uncovered baking method is especially useful. Foil traps steam to help the potatoes become tender, and the final uncovered minutes let excess moisture settle while the sausage develops browned edges.

Ingredients You’ll Need
Choose small red or yellow potatoes because their thin skins and firm texture work well in a casserole. You can quarter them or cut them into pieces about 1 inch in size, but try to keep the pieces similar so they cook evenly.
Smoked sausage or kielbasa is the easiest choice for this recipe. Slice it into 1/2-inch rounds so each serving gets plenty of sausage and the cut sides have room to brown during the uncovered baking time.
- Fresh green beans: Trim the ends and cut the beans in half for easy serving.
- Yellow onion: Sliced or chopped onion softens in the broth and adds gentle sweetness.
- Chicken broth: Low-sodium broth gives the vegetables moisture while allowing you to control the salt.
- Garlic and paprika: These seasonings add savory depth and a subtle smoky note.
- Butter or olive oil: Either option helps the seasonings cling to the ingredients and contributes richness.
Smoked sausage can vary in saltiness, so the listed kosher salt is a starting point rather than a reason to add more automatically. If you use regular-sodium broth, taste the finished casserole before adding any extra salt.

How to Make It Step-by-Step
Step 1: Begin by heating the oven to 375°F and lightly greasing a 9-by-13-inch baking dish. This temperature gives the casserole enough heat to cook the potatoes while allowing the sausage to brown during the final uncovered stage.
Step 2: Prepare all of the ingredients before assembling the dish. Slice the smoked sausage into 1/2-inch rounds, cut the potatoes into quarters or 1-inch pieces, trim and halve the green beans, and slice or chop the small yellow onion.
Step 3: Add the sausage, potatoes, green beans, onion, and minced garlic to the baking dish. Keeping everything in the dish from the start makes this a practical weeknight meal with very little cleanup.
Step 4: Drizzle in the butter or olive oil, then sprinkle on the kosher salt, black pepper, paprika, and optional Italian seasoning or thyme. Toss gently but thoroughly so the vegetables and sausage are coated without crushing the potato pieces.
Step 5: Pour 1 cup of low-sodium chicken broth around the ingredients. Pouring it around the food helps the seasonings remain on the sausage and vegetables while the broth collects in the bottom to create moist cooking conditions.
Step 6: Cover the dish tightly with foil and bake for 30–35 minutes. Check the potatoes near the end of this stage; they should be nearly tender when pierced with a fork, but they do not need to be completely finished yet.
Step 7: Remove the foil and return the casserole to the oven for 10–15 minutes. The potatoes should become fully tender, the green beans should be cooked but not mushy, and the sausage should show browned edges.
Step 8: Stir gently before serving, taking care not to crumble the potatoes. Taste a small portion and adjust the pepper or salt only if needed.
Pro Tips for Tender Potatoes and Flavorful Sausage
The most important detail is potato size. Large chunks may still be firm when the beans and sausage are ready, so cut particularly large or hard potatoes into smaller pieces before they go into the dish.
For a faster bake and consistently tender potatoes, parboil them for 5–7 minutes. Drain them well, then assemble the casserole as directed; this is helpful when the potatoes are unusually dense or when you are cooking for guests.
Do not skip the foil during the first baking stage. Without a tight cover, the broth can evaporate too quickly and the potatoes may take longer to soften.
Use a gentle hand when stirring. The potatoes become soft as they bake, and folding the ingredients carefully keeps the casserole attractive when it reaches the table.
Freshly cracked black pepper can be added at the end for a sharper finish. A small sprinkle of parsley is also welcome if you have it, although the casserole is flavorful without an additional garnish.
Easy Casserole Variations
For a pantry shortcut, replace the fresh green beans with one 14–15-ounce can of drained green beans and replace the fresh potatoes with one 14–15-ounce can of drained sliced potatoes. Since canned vegetables are already cooked, reduce the covered baking time to approximately 20–25 minutes, then uncover and bake until the sausage is browned.
For a creamy version, whisk one 10.5-ounce can of condensed cream of mushroom soup with 1/2 cup milk. Pour the mixture over the sausage and vegetables, then bake the casserole at 350°F for about 35–45 minutes.
You can also make this meal in a covered skillet rather than the oven. Simmer the sausage, potatoes, green beans, onion, and about 1 cup of broth for 20–30 minutes, checking the potatoes for tenderness before serving.
If you are planning a larger comfort-food spread, this sweet potato casserole makes a fitting side dish for a holiday-style table.
What to Serve With This Dinner
This casserole is substantial enough to serve on its own, especially when you want a complete meal without extra work. A crisp green salad can add freshness, while warm dinner rolls are useful for soaking up the seasoned broth at the bottom of the dish.
For a casual family table, place the casserole in the center and let everyone serve themselves. A simple fruit salad or light vegetable starter can balance the hearty sausage and potatoes without competing with their smoky flavor.
For entertaining, serve a small appetizer before dinner, such as these green goddess veggie dip cups. Their cool, fresh flavor provides a pleasant contrast to the hot casserole.
Storage and Reheating
Allow leftovers to cool, then transfer them to a covered container and refrigerate promptly. The casserole keeps well for a few days, and the flavors often taste even more blended after resting overnight.
Reheat individual portions in the microwave until hot, stirring carefully halfway through if needed. You can also reheat a larger portion in a covered oven-safe dish until warmed through, then remove the cover briefly if you want the sausage edges to regain some crispness.
Because the sausage is already cooked, the main reheating goal is to warm the dish evenly without drying out the potatoes. A spoonful of broth can be added if the leftovers seem dry.

Sausage, Green Bean & Potato Casserole
Ingredients
Method
- Heat the oven to 375°F and lightly grease a 9-by-13-inch baking dish. Slice the sausage into 1/2-inch rounds, cut the potatoes into quarters or 1-inch pieces, trim and halve the green beans, and slice or chop the onion.
- Place the sausage, potatoes, green beans, onion, and minced garlic in the prepared baking dish. Add the butter or olive oil, kosher salt, black pepper, paprika, and optional Italian seasoning or thyme.
- Toss the ingredients gently in the dish so the seasonings and fat coat the vegetables and sausage. Pour the chicken broth around the ingredients rather than directly over the top.
- Cover the baking dish tightly with foil and bake for 30–35 minutes. The covered baking time allows the broth and trapped steam to soften the potatoes while keeping the green beans moist.
- Remove the foil and continue baking for 10–15 minutes, until the potatoes are fully tender and the sausage has browned around the edges. If needed, test a potato with a fork before taking the casserole from the oven.
- Stir gently before serving so the broth, seasonings, sausage, and vegetables mingle without breaking up the potatoes. Taste carefully and adjust the salt and pepper, remembering that smoked sausage is already seasoned.
