How to Make Loaded Cajun Chicken and Sausage Pasta Casserole Recipe
Step 1: Prep and Cook the Pasta
Start by preheating your oven to 375°F (190°C) and lightly greasing your casserole dish—this ensures your masterpiece won’t stick and makes cleanup easier. Then cook the penne pasta just shy of al dente, as the noodles will finish cooking in the oven. Drain and set them aside, so they’re ready to soak up all the creamy Cajun goodness later.
Step 2: Sauté the Chicken and Sausage
Heat your olive oil in a large skillet over medium-high heat. Toss in the diced chicken breasts and season them with half of the Cajun seasoning. Cook for around 4 to 5 minutes until the chicken turns golden and is cooked through. Remove and set aside. Next, cook the sliced smoked Cajun sausage in the same skillet for 2 to 3 minutes until it’s lightly browned and fragrant. Keep it with the chicken for later.
Step 3: Cook the Veggies and Build the Sauce
Lower the heat to medium and add the chopped yellow onion and red bell pepper to the skillet. Sauté for 3 to 4 minutes until softened and aromatic. Stir in the minced garlic and cook for an extra minute. Pour in the chicken broth, heavy cream, the remaining Cajun seasoning, and the diced tomatoes with green chilies. Stir everything together and let it gently simmer so those bold flavors meld beautifully.
Step 4: Combine Pasta, Proteins, and Sauce
Return the par-cooked pasta, chicken, and sausage to the skillet with your simmering sauce. Toss everything until it’s evenly coated, and season with salt and pepper to your taste. This step is where your casserole truly comes to life, with every bite promising a mix of creaminess, spice, and a perfect hint of smoky meatiness.
Step 5: Bake Your Loaded Cajun Chicken and Sausage Pasta Casserole Recipe
Pour the mixture into the prepared casserole dish in an even layer. Generously top it with shredded mozzarella and sharp cheddar cheese. Slide it into your preheated oven and bake for 18 to 20 minutes, until the cheese is gloriously melted and bubbly. For that irresistible golden crust, switch your oven to broil for a few minutes, watching carefully so it doesn’t burn. Let the casserole rest for a few minutes once out of the oven before garnishing with freshly chopped parsley.
How to Serve Loaded Cajun Chicken and Sausage Pasta Casserole Recipe

Garnishes
A sprinkle of fresh parsley is a simple but effective way to add a burst of color and a touch of herbal brightness to your plate. If you want to elevate the presentation further, try adding some sliced green onions or even a dash of smoked paprika for extra visual and flavor appeal.
Side Dishes
This hearty casserole pairs wonderfully with a crisp green salad tossed in a light vinaigrette, which balances the richness with fresh, tangy notes. Roasted vegetables or garlic bread are fantastic options too, soaking up any extra sauce and rounding out the meal perfectly.
Creative Ways to Present
For a fun twist, serve the casserole in mini cast-iron skillets or individual ramekins to highlight personal portions. You could also jazz it up by layering in extra cheese between pasta and meats for a gooier, more decadent experience. Turning this into a buffet-style dish lets everyone customize with their favorite toppings like avocado slices, jalapeños, or hot sauce.
Make Ahead and Storage
Storing Leftovers
Once cooled to room temperature, transfer any leftovers into airtight containers and store them in the refrigerator. This Loaded Cajun Chicken and Sausage Pasta Casserole Recipe stays fresh and flavorful for up to 3-4 days, making it perfect for easy lunches or quick dinners during the week.
Freezing
If you want to save some for later, you can freeze portions of this casserole. Use freezer-safe containers or heavy-duty freezer bags, making sure to label with the date. Frozen casserole lasts well for up to 2 months, allowing you a speedy homemade meal anytime.
Reheating
Reheat refrigerated portions in the microwave or oven until warmed through, adding a splash of broth or cream if the pasta feels dry. When reheating from frozen, thaw overnight in the fridge first for best results, then follow the same warming directions to keep the flavors and textures just right.
FAQs
Can I use a different type of pasta for this casserole?
Absolutely! While penne is great for holding the sauce, you can use rigatoni, fusilli, or even elbow macaroni. The key is choosing a pasta shape that captures the creamy sauce well.
Is the Cajun seasoning very spicy?
Cajun seasoning has a nice kick but isn’t overwhelmingly hot. If you prefer milder flavors, start with less seasoning and adjust to taste as you cook.
Can I substitute heavy cream with something lighter?
You can use half-and-half or whole milk for a lighter casserole, but keep in mind the sauce won’t be quite as rich and creamy. Adding a bit of cream cheese can help keep the texture velvety.
What’s the best way to dice the chicken for even cooking?
Cut the chicken breasts into uniform, bite-sized cubes about 1-inch pieces. This ensures they cook evenly and remain tender rather than drying out during sautéing.
Can I make this casserole vegetarian?
Definitely! Omit the chicken and sausage, and add hearty vegetables like mushrooms, zucchini, or eggplant. You can also add plant-based sausage substitutes to keep the flavor profile similar.
