How to Make Cajun Hash Brown Casserole Recipe
Step 1: Prepare Your Oven and Pan
Start by preheating your oven to 350ºF to ensure it’s ready once your casserole is assembled. Lightly spray a 9×13-inch pan with cooking spray – this prevents sticking and helps in serving the cheesy layers effortlessly.
Step 2: Brown the Smoked Sausage
Heat the oil in a large skillet over medium-high heat and add the sliced smoked sausage. Cook it for 5 to 8 minutes until it’s beautifully browned and sizzling. This step unlocks the rich flavors of the sausage, which will infuse the entire dish.
Step 3: Mix All the Ingredients
In a large mixing bowl, combine the cooked chopped chicken, browned sausage, cream of chicken soup, sour cream, Cajun seasoning (start with 2 tablespoons and add more if you like it spicy), 1 1/2 cups of shredded cheddar cheese, half of the french fried onions, heavy cream if using, and the frozen frozen shredded hash browns. Stir everything gently but thoroughly. The mixture should be creamy and well coated with the seasonings.
Step 4: Assemble the Casserole
Pour your flavorful mixture into the prepared baking pan, leveling it out evenly. Sprinkle the remaining 1/2 cup cheddar cheese and the other half of the crispy french fried onions on top. This topping will give a golden, crunchy finish after baking.
Step 5: Bake to Perfection
Bake uncovered at 350ºF for 50 to 60 minutes until the casserole is bubbly around the edges and golden on top. The hash browns inside will cook through and develop those irresistibly crispy edges, making every bite memorable.
How to Serve Cajun Hash Brown Casserole Recipe

Garnishes
This casserole shines on its own, but a few thoughtful garnishes can make it even better. Sprinkle freshly chopped green onions or parsley on top for a fresh, bright contrast to the richness. A dollop of sour cream on the side adds creamy indulgence with every forkful.
Side Dishes
Given how hearty and flavorful the Cajun Hash Brown Casserole Recipe is, lighter sides complement it best. A crisp green salad with a tangy vinaigrette or some steamed green beans keeps the meal balanced and refreshing. If you want to stay on theme, try simple sautéed vegetables with a touch of garlic and lemon.
Creative Ways to Present
You can serve this casserole straight from the pan for a cozy family meal, or scoop individual portions onto plates for a more elegant presentation. For a fun twist, serve it in mini casserole dishes or ramekins for single servings at a casual brunch or potluck. Layer it with extra cheese on top for an au gratin look that’s sure to impress.
Make Ahead and Storage
Storing Leftovers
This Cajun Hash Brown Casserole Recipe stores beautifully in an airtight container in the refrigerator for up to 3 days. The flavors actually deepen overnight, making leftovers just as satisfying as fresh-out-the-oven servings.
Freezing
You can freeze the casserole before baking by assembling it in a freezer-safe dish and covering it tightly with foil and plastic wrap. It will keep well for up to 2 months. When you’re ready to enjoy, thaw it overnight in the fridge before baking as directed.
Reheating
Reheat leftovers in the oven at 350ºF, covered with foil for about 20 minutes, then uncover and bake a few more minutes until bubbly. This keeps the casserole moist while restoring its crispy top. Microwaving works in a pinch but may soften the crispy onions.
FAQs
Can I make this casserole vegetarian?
Absolutely! Simply omit the chicken and smoked sausage, and consider adding sautéed mushrooms, bell peppers, or other hearty vegetables to keep it satisfying while maintaining that creamy, cheesy charm.
How spicy is the Cajun seasoning in this recipe?
The heat level depends on the Cajun seasoning you choose and how much you add. Starting with 2 tablespoons offers a warm, flavorful kick without being overwhelming, but you can always add more for extra spice to suit your taste.
Can I use fresh potatoes instead of frozen hash browns?
While fresh potatoes can work, frozen shredded hash browns save so much prep time and have a consistent texture. If using fresh, make sure to grate them finely and squeeze out excess moisture before mixing.
Is there a way to make this recipe lighter?
Yes! Swap sour cream for Greek yogurt, use reduced-fat cheese, and skip the heavy cream to lighten it up without sacrificing too much of the creamy texture that makes this casserole so indulgent.
Can I double this recipe for a larger group?
Definitely. Just use a larger baking dish or two pans, and adjust baking times accordingly—start checking for doneness around the usual time as oven variations can affect baking.
Final Thoughts
There’s just something so special about a Cajun Hash Brown Casserole Recipe that brings people back for seconds, whether it’s the creamy sauce, the cheesy goodiness, or the bold Cajun spices.
