Why You Will Love This Recipe

There are a million pasta recipes out there, so why choose this one? Here is why this Cajun Cream Cheese Chicken Pasta Bake stands out from the crowd:

• Incredible Texture: The cream cheese melts down into a glossy, smooth sauce that coats the pasta perfectly without separating. It adds a slight tang that cuts through the richness of the dairy.
• Customizable Heat: Cajun seasoning is famous for its kick, but you are in total control. You can make this mild enough for toddlers or spicy enough to make your brow sweat.
• One-Pan Magic (Almost): While you boil the pasta separately, the sauce and chicken come together in one skillet before being baked to bubbly perfection.
• Leftover Gold: Unlike some cream sauces that break when reheated, the cream cheese stabilizes this sauce, making leftovers taste just as good (if not better) the next day.

Ingredients You Will Need

To make this luscious pasta bake, you will need simple ingredients found in any grocery store. Quality matters here, especially with the spices and cheese.

For the Chicken and Pasta:

• Chicken Breast: 1.5 lbs, boneless and skinless. You want to cut this into bite-sized 1-inch cubes so they cook quickly and evenly.
• Pasta: 1 lb (16 oz). Rotini or Fusilli is the absolute best choice here because the corkscrew shape traps the thick sauce and spices. Penne or cavatappi also work well.
• Olive Oil: 2 tablespoons, divided. Used for searing the chicken and sautéing the aromatics.
• Cajun Seasoning: 3 tablespoons total. You will use some for the chicken and some for the sauce. Look for a blend that includes paprika, cayenne, garlic powder, onion powder, and oregano.
• Smoked Paprika: 1 teaspoon. Adds an extra layer of smokiness and vibrant color.
• Salt and Black Pepper: To taste.

For the Creamy Cajun Sauce:

• Cream Cheese: 8 oz block, full fat, softened to room temperature. Do not use the tub variety; the block style melts much smoother.
• Heavy Cream: 1 cup. This provides the liquid base for the sauce. You can sub with half-and-half for a lighter version, though the sauce will be thinner.
• Chicken Broth: 1/2 cup. Helps to deglaze the pan and adds savory depth.
• Garlic: 4 cloves, minced. Fresh garlic is non-negotiable for that aromatic punch.
• Parmesan Cheese: 1/2 cup, freshly grated. Adds saltiness and umami.
• Butter: 2 tablespoons.
• Onion: 1 small yellow onion, finely diced.
• Bell Pepper: 1 red bell pepper, diced (optional, but adds great sweetness and crunch).
• Mozzarella Cheese: 1 cup, shredded. This is for the “bake” part—it creates that gooey, stretchy cheese pull on top.
• Fresh Parsley: For garnish.

Step-by-Step Instructions

Follow these steps to achieve the perfect balance of spicy chicken and creamy pasta.

1. Prep the Pasta

Bring a large pot of salted water to a rolling boil. Add your rotini pasta and cook it to al dente according to the package instructions. You want it slightly undercooked (firm to the bite) because it will continue cooking in the oven later. Reserve about 1/2 cup of the starchy pasta water before draining. Drain and set aside.

2. Season and Sear the Chicken

While the water is boiling, place your cubed chicken breast in a bowl. Toss it with 1.5 tablespoons of the Cajun seasoning, the smoked paprika, a pinch of salt, and pepper. Ensure every piece is well-coated.

Heat 1 tablespoon of olive oil in a large, deep skillet or Dutch oven over medium-high heat. Once hot, add the chicken in a single layer. Sear for 3-4 minutes per side until a golden-red crust forms and the chicken is cooked through. Remove the chicken from the pan and set it aside on a plate. (Do not wipe the pan! Those brown bits at the bottom are pure flavor).

3. Sauté Aromatics

Reduce the heat to medium. Add the butter and remaining tablespoon of olive oil to the same skillet. Add the diced onion and red bell pepper. Sauté for about 5 minutes until the onions are translucent and soft. Add the minced garlic and cook for another minute until fragrant, being careful not to burn it.

4. Create the Cream Cheese Base

Deglaze the pan with the chicken broth, scraping up any browned bits from the bottom with a wooden spoon. Add the block of softened cream cheese and the remaining 1.5 tablespoons of Cajun seasoning. Whisk or stir constantly until the cream cheese has completely melted and is smooth.

5. Finish the Sauce

Pour in the heavy cream and bring the mixture to a gentle simmer. Let it bubble gently for 2-3 minutes to thicken slightly. Stir in the grated Parmesan cheese until melted. If the sauce looks too thick, splash in a little of the reserved pasta water to reach your desired consistency. Taste and adjust salt or Cajun seasoning if needed.

6. Combine and Assemble

Preheat your oven to 375°F (190°C). Add the cooked pasta and the seared chicken (along with any juices on the plate) back into the skillet with the sauce. Toss everything gently until the pasta and chicken are thoroughly coated in the glossy orange sauce.

7. Bake to Perfection

If your skillet is oven-safe, smooth the top of the pasta mixture and sprinkle the shredded mozzarella cheese evenly over the top. If your skillet isn’t oven-safe, transfer the mixture to a 9×13 baking dish first, then top with cheese.

Bake for 15-20 minutes, or until the cheese is melted and bubbly and the sauce is bubbling around the edges. For a golden crust, switch the oven to broil for the last 2-3 minutes (watch it closely so it doesn’t burn!).

8. Garnish and Serve

Remove from the oven and let it rest for 5 minutes. This allows the sauce to set slightly and cling better to the pasta. Garnish generously with fresh chopped parsley for a pop of color and freshness. Serve hot!

Tips for the Perfect Pasta Bake

• Room Temperature Cream Cheese: This is the most crucial tip. If your cream cheese is cold, it will be lumpy and difficult to melt into a smooth sauce. Take it out of the fridge at least 30 minutes before cooking.
• Don’t Overcook the Pasta: Since you are baking the dish after boiling the pasta, if you boil it to “soft” initially, it will turn to mush in the oven. Aim for a firm bite (al dente).
• Spice Control: Cajun seasoning varies wildly by brand. Some are very salty; some are very spicy. Taste your seasoning first. If it’s salt-heavy, hold back on adding extra salt to the dish. If you love heat, add a pinch of cayenne pepper to the sauce.
• Shred Your Own Cheese: Pre-shredded bagged cheese contains anti-caking agents (like potato starch) that prevent it from melting smoothly. For that gooey, high-gloss finish seen in photos, buy blocks of Parmesan and Mozzarella and grate them yourself.

Variations and Substitutions

Make this recipe your own with these delicious twists:

Protein Swap: This sauce is incredible with Andouille sausage or shrimp. For a surf-and-turf Cajun pasta, add shrimp during the last few minutes of the sauce simmering, or sear sausage slices along with the onions.

Add More Veggies: Boost the nutrition by adding spinach, broccoli florets, or zucchini. Stir fresh baby spinach into the hot sauce right before adding the pasta; it will wilt instantly.

Gluten-Free Option: Simply swap the wheat pasta for your favorite gluten-free pasta (chickpea or brown rice pasta works well) and ensure your Cajun seasoning blend is gluten-free.

Lighter Version: Substitute the heavy cream with milk and use low-fat cream cheese. The sauce will be thinner and less rich, but still tasty. You may need to use a little cornstarch slurry to thicken it if you skip the cream.

Storage and Reheating

Storage: Store leftovers in an airtight container in the refrigerator for up to 3-4 days. This dish actually tastes amazing the next day as the flavors have time to meld.

Reheating: Creamy pastas can sometimes separate when reheated. To prevent this, reheat gently on the stove over low heat with a splash of milk or water to loosen the sauce. If using the microwave, heat in short 30-second bursts, stirring in between to ensure even heating.

Freezing: We do not recommend freezing this dish. Cream cheese and dairy-heavy sauces tend to become grainy and separate when frozen and thawed.

Frequently Asked Questions

Can I make this ahead of time?
Yes! You can assemble the entire dish up to the point of baking. Cover it tightly with foil and refrigerate. When ready to eat, bake it for 25-30 minutes (you may need a few extra minutes since it’s starting from cold).

What is a good substitute for Cajun seasoning?
If you don’t have a pre-made blend, mix 1 tbsp paprika, 1 tsp garlic powder, 1 tsp onion powder, 1 tsp oregano, 1 tsp thyme, 1/2 tsp cayenne pepper, and salt/pepper to taste. Creole seasoning is also a very close substitute.

Why is my sauce grainy?
Grainy sauce usually happens if the heat was too high when the dairy was added, or if the cheese was pre-shredded. Always keep the heat at a gentle simmer (not a rolling boil) once the cream and cheese are added.
