How to Make Loaded Chicken and Cajun Sausage Pasta Casserole Recipe
Step 1: Prepare Your Oven and Pasta
Begin by preheating your oven to 375°F (190°C) and greasing a large casserole dish so your masterpiece doesn’t stick. While the oven warms, cook the penne pasta just shy of al dente—this ensures it won’t turn mushy in the oven but will soak up just enough sauce to be tender and flavorful. Drain and set it aside for later.
Step 2: Cook the Chicken
Heat olive oil in a large skillet over medium-high heat and add the diced chicken, seasoning it halfway with the Cajun seasoning. This gives the chicken a nice, spicy crust once cooked. Sauté for about 4 to 5 minutes until the chicken turns golden and is cooked through. Remove the chicken and set it aside—don’t worry, we’ll bring it all back together soon.
Step 3: Brown the Cajun Sausage
In the same skillet, toss in your sliced smoked Cajun sausage and cook for 2 to 3 minutes, allowing it to brown lightly and release its smoky oils. This step intensifies the flavor and helps the sausage crisp up a bit. Remove and keep it with the chicken for the next step.
Step 4: Sauté the Vegetables
Now lower the heat to medium and add the chopped onion and red bell pepper to the skillet. Sauté for 3 to 4 minutes until they soften wonderfully and release their sweetness. Add minced garlic and cook for an additional minute—watch out, that aroma will make your kitchen smell incredible!
Step 5: Build the Creamy Sauce
Pour in the chicken broth, heavy cream, and the remaining Cajun seasoning into the skillet. Stir in the diced tomatoes with green chilies, then bring everything to a gentle simmer. This sauce is where the magic happens, marrying smoky, spicy, and creamy flavors into one irresistible base.
Step 6: Combine Pasta, Chicken, and Sausage
Return the penne pasta, cooked chicken, and Cajun sausage to the skillet. Give everything a good toss to combine all the flavors evenly, seasoning with salt and pepper to taste. This step invites all the ingredients to mingle and soak up that delicious sauce together.
Step 7: Assemble and Bake
Transfer this hearty mixture into your prepared casserole dish. Generously top it with shredded mozzarella and sharp cheddar cheese for that perfect cheesy crown. Bake in the oven for 18 to 20 minutes until the cheese is melted, bubbly, and inviting. For an extra golden crust, broil for 2 to 3 minutes at the end—just keep a close eye so it doesn’t burn.
Step 8: Rest and Garnish
Once out of the oven, let the casserole rest for a few minutes to set. Sprinkle freshly chopped parsley on top for a fresh, herbal note and that wonderful pop of color. Now it’s ready to dive in and enjoy!

Garnishes
The fresh parsley garnish isn’t just for looks; it cuts through the richness with its bright, herbal freshness, enhancing every bite. You might also sprinkle a touch of extra Cajun seasoning or even a few sliced green onions for added color and zing, making the dish even more inviting.
Side Dishes
This casserole is a full meal in itself, but if you want to complement it, consider serving a crisp garden salad with a tangy vinaigrette for freshness, or roasted veggies like asparagus or broccoli that offer a nice contrast in texture and nutritional balance to the creamy pasta.
Creative Ways to Present
For a fun twist, try serving scoops of the casserole inside halved baked sweet potatoes for an unexpected presentation. Alternatively, turning leftovers into individual portions baked in small ramekins is a lovely way to personalize the dish for guests or family members.
Make Ahead and Storage
Storing Leftovers
After enjoying your casserole, allow any leftovers to cool completely, then place them in an airtight container. Stored in the refrigerator, they’ll keep well for up to 3 to 4 days while maintaining that creamy texture and bold flavor.
Freezing
You can freeze this dish if you want to prep ahead or save for busy nights. To do this, assemble the casserole in a freezer-safe dish but don’t bake it yet. Cover tightly with foil and freeze for up to 3 months. When ready, bake directly from frozen, adding extra time to ensure it heats thoroughly.
Reheating
Reheat leftovers gently in the oven at 350°F (175°C) until warmed through, which helps preserve the creamy sauce without drying it out. Alternatively, microwave individual servings, but add a splash of cream or broth to keep it moist and delicious.
FAQs
Can I use other types of pasta for this casserole?
Absolutely! While penne is perfect for catching the sauce, you can substitute with rigatoni, rotini, or even fusilli. Just be sure to cook the pasta just shy of al dente to avoid mushiness after baking.
Is this recipe very spicy?
The Cajun seasoning and diced tomatoes with green chilies do add some heat, but it’s usually mild to medium spice. You can adjust by adding more or less seasoning or opting for mild sausage if you prefer a gentler kick.
Can I make this dish vegetarian?
Yes! Simply swap the chicken and sausage for hearty vegetables like mushrooms, zucchini, or plant-based sausage alternatives. You might want to use vegetable broth instead of chicken broth for a fully vegetarian version.
What cheese works best for topping?
The combination of mozzarella and sharp cheddar gives the casserole a beautiful melt and flavor balance. You could experiment by adding Parmesan for an extra savory boost or Monterey Jack for creaminess.
How long does it take to prepare this casserole?
Including prep, cooking, and baking, this recipe takes about 55 minutes from start to finish, making it a great option for a satisfying dinner without spending hours in the kitchen.
