Looking for a side dish that transforms an ordinary dinner into something extraordinary? This Cajun potato casserole brings the bold flavors of Louisiana straight to your table. Rich, creamy, and packed with authentic seasonings, it’s the perfect companion to any main course.
Why russet potatoes make the best base
Russet potatoes are the foundation of an exceptional Cajun potato casserole. Their high starch content creates the perfect creamy texture when combined with other ingredients. These potatoes hold their shape while becoming tender, preventing a mushy final product.
When selecting russets, choose firm potatoes without green spots or sprouts. Medium-sized potatoes work best as they cook evenly and are easier to cut into uniform pieces. Store them in a cool, dark place until ready to use.
The authentic trinity of Cajun cooking
The foundation of Cajun cooking starts with onions, celery, and bell peppers. This combination adds depth and authentic flavor to the casserole. Dice these vegetables uniformly to ensure even cooking and distribution throughout the dish.
For best results, sauté the trinity until the onions become translucent and the celery softens. This process releases their natural sweetness and creates a aromatic base for the casserole.
Selecting the right andouille sausage
Quality andouille sausage brings smoky depth and authentic Cajun flavor to this casserole. Choose sausage that’s firm and has a good ratio of meat to fat. Slice it into uniform pieces to ensure even distribution throughout the dish.
If andouille isn’t available, smoked kielbasa can work as a substitute. The key is finding a sausage with enough spice and smokiness to complement the other ingredients.
The secret to the perfect creamy sauce
The creamy sauce that binds this casserole together requires a careful balance of ingredients. Heavy cream forms the base, while a combination of sharp cheddar and Parmesan cheese adds richness and depth. Sour cream brings tanginess that cuts through the richness.
Room temperature dairy products blend more smoothly and prevent curdling. Grate your own cheese rather than using pre-shredded varieties for better melting and texture.
Essential spices for authentic Cajun flavor
The right balance of spices transforms this from a basic potato casserole into an authentic Cajun dish. A blend of paprika, garlic powder, onion powder, oregano, thyme, and cayenne creates the perfect seasoning base.
Start with a moderate amount of cayenne and adjust according to your heat preference. Remember that the heat level will intensify as the casserole bakes.
Tips for perfect potato texture
Achieving the ideal potato texture requires attention to detail. Cut the potatoes into uniform pieces to ensure even cooking. Par-boil them just until fork-tender – overcooking will lead to a mushy casserole.
Drain the potatoes thoroughly and let them steam dry for a few minutes. This prevents excess moisture from making the casserole watery.
Make-ahead and storage options
This casserole can be assembled up to 24 hours in advance. Cover tightly with foil and refrigerate until ready to bake. Add an extra 10-15 minutes to the baking time if cooking from cold.
Leftovers stay fresh in an airtight container for up to three days. Reheat in the oven rather than the microwave to maintain the best texture.
Serving suggestions and pairings
This versatile casserole pairs beautifully with grilled meats, roasted chicken, or seafood. For a complete meal, serve alongside a fresh green salad or roasted vegetables to balance the richness.
Consider garnishing with fresh parsley or green onions just before serving to add color and fresh flavor.
With its perfect balance of spices, creamy texture, and hearty ingredients, this Cajun potato casserole elevates any meal from ordinary to memorable. The combination of authentic ingredients and careful preparation creates a side dish that might just outshine the main course.

kcalA creamy, spicy Southern-style potato casserole loaded with andouille sausage and authentic Cajun seasonings
Ingredients
3 pounds russet potatoes, peeled and thinly sliced
1 pound andouille sausage, sliced
1 large onion, diced
2 celery stalks, diced
1 green bell pepper, diced
3 cups heavy cream
2 cups sharp cheddar cheese, freshly grated
1 cup Parmesan cheese, freshly grated
2 tablespoons Tony Chachere’s Original Creole Seasoning
4 cloves garlic, minced
1/2 cup sour cream
Directions
- Preheat your oven to 350°F and position the rack in the middle. Grease a 9×13 inch baking dish and place it on a baking sheet to catch any potential spills.
- In a large skillet over medium heat, cook the sliced andouille sausage until browned on both sides, about 5-7 minutes. Remove the sausage with a slotted spoon and set aside, leaving the rendered fat in the pan.
- In the same skillet with the sausage fat, sauté the diced onion, celery, and bell pepper until softened, about 5-6 minutes. Add the minced garlic and cook for another 30 seconds until fragrant.
- In a large bowl, combine the heavy cream, sour cream, and Creole seasoning. Stir well to ensure the seasoning is evenly distributed throughout the mixture.
- Layer half of the sliced potatoes in the prepared baking dish, slightly overlapping them. Top with half of the sautéed vegetables, half of the browned sausage, and pour half of the cream mixture over everything.
- Sprinkle half of both the cheddar and Parmesan cheeses over the cream mixture. Repeat the layers with the remaining ingredients, ending with the cheese on top.
- Cover the dish with aluminum foil and bake for 45 minutes. Remove the foil and continue baking for an additional 25-30 minutes, until the potatoes are tender when pierced with a knife and the top is golden brown.
- Let the casserole rest for 15 minutes before serving. This allows the cream sauce to thicken and makes it easier to serve neat portions.
Notes
- Use a mandoline slicer to get uniformly thin potato slices for even cooking
- For best results, grate the cheese fresh rather than using pre-shredded varieties
- The casserole can be assembled up to 24 hours in advance and refrigerated before baking
- Leftovers can be stored in an airtight container for up to 3 days and reheated in the oven at 325°F
