- 1 cup yellow onion, finely chopped
- 3 garlic cloves, minced
Signature seasoning blend
- 1 teaspoon Slap Ya Mama seasoning or another Creole blend
- 1 teaspoon garlic powder
- 1 teaspoon freshly ground black pepper
- ½ teaspoon red-pepper flakes, adjust to taste

- ¼ cup water, helps the sausage caramelize evenly
Equipment

- 6 quart slow cooker
How To Make Sausage Green Bean Potato Casserole
- Heat the oven
Set the temperature to 400 °F (204 °C). Lightly grease a 9 × 13 inch baking dish so nothing sticks later. - Season the potatoes
Rinse and halve the baby potatoes, then drop them into a large zip-top bag. Pour in the vegetable oil, Slap Ya Mama seasoning, garlic powder, black pepper, and red-pepper flakes. Seal the bag and shake until every potato is glistening and well coated. This step builds the flavor foundation. - Brown the sausage
Place a wide skillet over medium-high heat. Add the sausage coins plus the quarter cup of water. Cook, stirring now and then, until the water evaporates and the sausage develops deep golden edges, roughly 8 minutes. Browning intensifies the smoky taste. - Combine sausage with potatoes
Let the sausage cool for one minute so it does not melt the plastic, then funnel it into the potato bag. Reseal and give another quick shake. - Sauté the aromatics
Melt the butter in the same skillet. Add chopped onion and minced garlic. Cook until the onion turns translucent and the garlic smells sweet, about 4 minutes. This creates a savory base that perfumes the whole dish. - Add aromatics to the mix
Cool the onion mixture for a couple of minutes, then scrape it into the bag. Seal and toss so every bite picks up that buttery garlic flavor. - Finish the filling
Tip the drained green beans into the bag. Seal once more and shake gently until beans, potatoes, and sausage look evenly distributed. - Load the baking dish
Empty the entire bag into the prepared dish, spreading the contents in an even layer. Cover snugly with foil. Foil traps steam so the potatoes cook through without drying out. - Bake until tender
Slide the dish onto the center rack and bake for about 40 minutes. The casserole is ready when a fork slips easily into the thickest potato piece. - Serve hot
Remove the foil carefully to avoid steam burns. Let the casserole rest for two minutes to settle, then spoon onto plates and enjoy while piping hot.
Variations
- Cheesy bake: Stir in one and a half cups of shredded cheddar or Gruyère during the final five minutes of baking so it melts into a bubbly topping.
- Spicy Cajun: Double the Creole seasoning, add a pinch of cayenne, and finish each serving with a splash of your favorite hot sauce.
- Italian herb: Swap the Creole blend for dried Italian seasoning, use sweet Italian chicken sausage, and sprinkle grated Parmesan on top at the end.
- Extra veggies: Fold in a cup of diced bell peppers, sliced mushrooms, or small broccoli florets along with the green beans for more color and nutrients.
Serving and Storage Tips
Perfect pairings
- Garlic bread for soaking up buttery juices
- Skillet cornbread that adds a sweet crunch
- Crisp side salad tossed with a light vinaigrette
- Warm crescent rolls if you want a soft, flaky bite
Storing leftovers
- Refrigerator: Cool completely, transfer to an airtight container, and keep chilled for 3 to 4 days
- Freezer: Portion into freezer-safe boxes, label, and freeze up to 3 months; thaw overnight in the fridge
Reheating for best texture
- Oven: Place in a baking dish, cover lightly with foil, and warm at 350 °F for about 15 minutes until heated through
- Microwave: Heat individual servings in 60-second bursts, stirring between rounds to prevent cold pockets
Helpful Notes
- Choose uniform potatoes
Halving larger creamer potatoes or quartering extra large ones helps everything cook at the same speed. - Dry the green beans
After draining, pat canned or thawed beans with paper towels; less surface moisture means the casserole will not turn watery. - Crispy finish tip
During the last ten minutes of baking, slide the foil aside or remove it fully so the potatoes can brown. - Make-ahead option
Assemble the casserole up to one day early, cover, and refrigerate; add five extra minutes to the bake time to compensate for the cold start. - Sheet pan swap
Line a large sheet pan with parchment, spread the mixture out in a single layer, and roast at 425 °F for 30 to 35 minutes turning once for maximum caramelization. - Slow cooker method
Combine all ingredients in a six-quart slow cooker, cover, and cook on high for 3 hours or on low for 6 hours until potatoes are tender. - Flavor twist idea
A squeeze of fresh lemon juice or a sprinkle of chopped parsley right before serving brightens the rich sausage flavors.

Frequently Asked Questions
How do you keep green bean casserole from getting mushy?
Use fresh or well-drained frozen beans, pat them dry with paper towels, and bake uncovered for the last ten minutes so excess steam can escape. Avoid overbaking, which softens the beans.
How long does sausage casserole take to cook?
Once assembled, the oven method needs about forty minutes at 400 °F to reach fork-tender potatoes and fully heated sausage and beans.
How long does it take for green bean casserole to go bad?
At room temperature the dish should be refrigerated within two hours. Stored in an airtight container it lasts three to four days in the fridge or up to three months in the freezer.
Can you overcook green bean casserole?
Yes. Overcooking causes the beans to lose their bright color and become mushy and the potatoes to turn pasty. Stick to the recommended time and check doneness early.
Why didn’t my green bean casserole thicken?
Excess liquid is often the culprit. Fully drain canned beans, pat frozen beans dry, and remove the foil cover near the end so moisture can evaporate. If needed, bake a few extra minutes uncovered.
Should you prep green bean casserole the night before?
Absolutely. Assemble up to 24 hours ahead, cover, and refrigerate. When ready to bake, let the dish sit at room temperature for fifteen minutes or add five extra minutes to the oven time.
