Honestly, this recipe is a go-to in my house whenever I want to feed a crowd without spending hours juggling pots and pans. It’s so easy, you might even call it a weeknight hero.

What Ingredients You Will Need

This creamy Cajun chicken pasta bake uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most of these are pantry staples, and you can swap a few things to suit your taste or dietary needs.

• For the Pasta Bake:
• 2 cups (200g) uncooked penne or rigatoni (I’ve tried both—penne holds the sauce beautifully)
• 1 lb (450g) boneless skinless chicken breasts, cut into bite-sized chunks
• 2 tbsp Cajun seasoning (homemade or store-bought; I love Tony Chachere’s for authentic flavor)
• 1 tbsp olive oil (for sautéing the chicken)
• 1 red bell pepper, diced (adds color and sweetness)
• 1 small yellow onion, finely chopped
• 3 cloves garlic, minced (fresh is best—don’t skimp!)
• 1 can (14 oz/400g) diced tomatoes, drained (fire-roasted if you want a smoky twist)
• 1/2 cup (120ml) chicken broth (low-sodium preferred; homemade if you have it)
• 1 cup (240ml) heavy cream (or use half-and-half for a lighter version)
• 1 cup (100g) shredded mozzarella cheese (for that gooey topping)
• 1/2 cup (50g) grated Parmesan cheese (adds salty punch)
• 2 tbsp cream cheese (softened; makes the sauce extra silky)
• 1/4 cup (15g) chopped fresh parsley (for garnish; optional but highly recommended)
• Salt and black pepper to taste
• Optional Add-Ins:
• 1/2 cup (75g) frozen peas (for a pop of color and sweetness)
• 1 cup (100g) sliced mushrooms (adds earthy depth)
• 1/2 tsp smoked paprika (for extra smokiness)
• Red pepper flakes (if you like even more heat!)

Ingredient Tips:

• For the chicken, I recommend air-chilled breasts for the best texture.
• Use whole milk mozzarella for maximum melt.
• If you need a gluten-free option, swap regular pasta for your favorite GF brand—just check the cooking time.
• Swap in turkey or even tofu for the chicken if you want a twist.
• Can’t find Cajun seasoning? Mix paprika, garlic powder, onion powder, cayenne, oregano, and thyme—easy!

Equipment Needed

• Large oven-safe skillet or 9×13-inch (23x33cm) baking dish: I use a deep ceramic casserole for even heat and easy serving.
• Medium saucepan: For boiling the pasta (if you don’t have a skillet large enough for one-pan prep).
• Cutting board and sharp knife: Chunking up chicken and veggies is much easier with a sturdy board.
• Wooden spoon or spatula: For stirring the sauce and tossing everything together.
• Measuring cups and spoons: Precision matters for seasoning and sauce!
• Colander: For draining pasta (if you par-cook separately).
• Aluminum foil: Useful to tent the bake if it browns too quickly.

If you don’t own a large skillet, a simple Pyrex or metal pan works fine. I’ve made this in a cheap nonstick pan and the crust still comes out golden. For knife care, I always dry mine right after washing (learned that the hard way after a rusty blade ruined my chopped herbs). Honestly, you don’t need anything fancy—just tools that get the job done.

Preparation Method

1. Prep the Pasta:
   
   Bring a large pot of salted water to a boil. Add 2 cups (200g) penne and cook for 6-7 minutes—just until al dente (it will finish cooking in the oven). Drain and set aside. Tip: Don’t overcook, or your pasta will get mushy after baking.
2. Season the Chicken:
   In a bowl, toss 1 lb (450g) chicken chunks with 2 tbsp Cajun seasoning, a pinch of salt, and black pepper until evenly coated. If you have time, marinate for 15 minutes for deeper flavor.
3. Sear the Chicken:
   Heat 1 tbsp olive oil in a large oven-safe skillet over medium-high. Add the chicken and cook for 4-5 minutes, stirring occasionally, until browned but not fully cooked through. Remove to a plate and set aside.
4. Sauté Vegetables:
   In the same skillet, add the diced bell pepper, chopped onion, and minced garlic. Sauté for 3-4 minutes until softened and fragrant. Watch for browning—the sugar in peppers can caramelize fast.
5. Make the Sauce:
   Lower heat to medium. Stir in drained tomatoes, chicken broth, and heavy cream. Add 2 tbsp cream cheese and whisk until smooth and creamy. Sprinkle in a little more Cajun seasoning if you like it extra spicy.
6. Combine & Layer:
   Add the chicken back to the skillet along with the cooked pasta. Toss gently to coat everything in the sauce. Fold in peas or mushrooms if using. Taste and adjust salt and pepper as needed.
7. Add Cheese:
   Sprinkle 1 cup (100g) shredded mozzarella and 1/2 cup (50g) grated Parmesan evenly over the top. You want a thick, cheesy layer for that classic pasta bake crust.
8. Bake:
   Preheat oven to 375°F (190°C). Place the skillet or baking dish uncovered on the middle rack. Bake for 20-25 minutes, until cheese is melted and bubbly, and the edges start to turn golden brown. If cheese browns too fast, tent with foil halfway through.
9. Garnish & Serve:
   Remove from oven and let it sit for 5 minutes (makes slicing easier). Sprinkle with chopped parsley and serve hot.

Preparation Notes:

• If your sauce looks thin before baking, don’t worry—it’ll thicken up as the pasta absorbs the liquid.
• If using gluten-free pasta, reduce baking time by 3-5 minutes to avoid mushiness.
• The skillet method saves on dishes, but if you prefer, mix everything in a bowl and transfer to a casserole before baking.
• The aroma as it bakes is unreal—if you’re hungry, that last 5 minutes feels like forever!

Cooking Tips & Techniques

• Layer Your Flavors: Cajun seasoning isn’t just for the chicken—add a little to the sauce and taste before baking. I learned that the hard way after my first try tasted bland.
• Watch Your Pasta: Par-cook your noodles. Overcooked pasta can turn mushy and soak up too much sauce. I’ve made that mistake a few times when distracted.
• Use Full-Fat Dairy: If you want a truly creamy finish, don’t skimp on heavy cream and real mozzarella. Low-fat versions just don’t melt or thicken the same way.
• Rest Before Serving: Let the bake sit for 5-10 minutes after removing from the oven. This keeps the sauce from running everywhere when you scoop.
• Multi-Tasking: Chop veggies while the chicken browns. Get your cheeses grated as the sauce simmers. It saves time and keeps things moving.
• Consistency Matters: If the sauce is too thick before baking, add a splash of chicken broth. If it’s too thin, toss in an extra spoonful of cream cheese.
• Common Mistakes: Don’t forget to taste before baking! Sometimes the seasoning settles and needs a final stir.

Honestly, my first bake came out dry because I underestimated how much liquid the pasta would soak up—lesson learned! Now I always add a little extra broth or cream if the mixture seems dense. Don’t be afraid to adjust on the fly; this recipe is forgiving. For best results, use a deep dish so the cheese doesn’t spill over and burn. And if you want a crispy top, broil for 2 minutes right at the end (just watch closely—cheese burns fast!).

Variations & Adaptations

• Gluten-Free: Use your favorite gluten-free pasta. I like brown rice penne for texture, but chickpea pasta works too. Just keep an eye on the bake time—GF varieties cook quicker.
• Vegetarian: Skip the chicken and load up on mushrooms, zucchini, and spinach. I’ve made this version for friends and it’s just as creamy and satisfying.
• Dairy-Free: Swap out heavy cream for coconut cream, use vegan cheese, and dairy-free cream cheese. The Cajun flavors still shine through, and the texture is surprisingly rich.
• Extra Spicy: Add sliced jalapeños or an extra pinch of cayenne. For heat lovers, a dash of hot sauce in the sauce is awesome.
• Seasonal Twists: In summer, I toss in roasted corn and fresh cherry tomatoes. In winter, I add roasted butternut squash for a sweet note.
• Personal Favorite: I once added crispy bacon bits to the cheese topping—wow, the smoky crunch was a hit at our last family dinner!

Feel free to mix and match veggies or swap in turkey or tofu for chicken. If you’re cooking for folks with allergies, double-check your Cajun seasoning for hidden gluten or MSG. There’s really no wrong way to make this creamy Cajun chicken pasta bake your own.

Serving & Storage Suggestions

This creamy Cajun chicken pasta bake is best served piping hot, straight from the oven. The cheese layer bubbles and crisps up beautifully, making it a showstopper for your dinner table. For presentation, sprinkle with fresh parsley or scallions and serve with a wedge of lemon.

• Serving: Slice into generous portions and plate with a simple green salad or garlic bread. For a fancier spread, pair it with roasted asparagus or steamed broccoli.
• Drinks: I love serving this with iced tea, a cold lager, or a crisp Sauvignon Blanc—the acidity cuts through the richness.
• Storage: Leftovers keep well in an airtight container in the refrigerator for up to 4 days. The flavors actually deepen as it sits!
• Freezing: Wrap tightly in foil or freezer-safe containers and store for up to 2 months. Thaw overnight in the fridge before reheating.
• Reheating: Microwave individual portions or reheat in the oven at 350°F (175°C), covered with foil, until warmed through. Add a splash of broth or cream if it seems dry.

Honestly, the leftovers are my favorite for lunch—just scoop, zap, and enjoy. The Cajun spices mellow a bit overnight, making it even more comforting the next day.
