What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and that classic creamy texture—no complicated shopping list or hard-to-find spices. Everything gets tossed together in one pot, making cleanup a breeze. Here’s exactly what you’ll need to make this One Pot Creamy Cajun Chicken Alfredo Bake shine:

• For the Chicken & Pasta:
  • 2 large boneless, skinless chicken breasts (about 1 lb/450 g), cut into bite-sized pieces
  • 2 tablespoons Cajun seasoning (homemade or store-bought; I like Slap Ya Mama or Tony Chachere’s for an authentic flavor)
  • 1 tablespoon olive oil (for sautéing)
  • 12 ounces (340 g) uncooked penne pasta (ziti, rotini, or rigatoni work too—use gluten-free pasta if needed)
• For the Creamy Alfredo Sauce:
  • 3 cups (710 ml) low-sodium chicken broth
  • 1 1/2 cups (355 ml) heavy cream (or half-and-half for a lighter version)
  • 4 cloves garlic, minced (adds major flavor—don’t skip this!)
  • 1/2 teaspoon smoked paprika (for depth and extra smokiness)
  • 1/2 teaspoon onion powder
  • 1/2 teaspoon salt (plus more to taste)
  • 1/4 teaspoon black pepper
  • 1/4 teaspoon crushed red pepper flakes (optional, for extra heat)
• For the Cheesy Topping:
  • 1 cup (100 g) freshly grated Parmesan cheese (for richness—pre-grated is okay in a pinch, but fresh melts best)
  • 2 cups (200 g) shredded mozzarella cheese
  • 2 tablespoons chopped fresh parsley (optional, for color and freshness)

Ingredient Tips & Substitutions:

• Swap chicken for shrimp or turkey sausage for a fun twist—just adjust cooking times.
• Use dairy-free cream and cheese (like Violife or Kite Hill) for a lactose-friendly version. It works surprisingly well!
• Prefer whole wheat pasta? Go for it—just check the cooking time on the box.
• If you want extra veggies, toss in a handful of spinach or bell peppers before baking. I’ve added roasted broccoli a few times, and it’s always a hit!
• Don’t have Cajun seasoning? Make your own with paprika, garlic powder, onion powder, cayenne, and dried herbs.

These ingredients keep things easy and flexible. Trust me, you can swap, add, or skip things based on what you have. That’s the beauty of this One Pot Creamy Cajun Chicken Alfredo Bake—it always comes together deliciously.

Equipment Needed

• Large Oven-Safe Pot or Dutch Oven: You’ll want something big enough to hold all the pasta and sauce (at least 5-quart/4.7L capacity). Cast iron or enameled Dutch ovens are my go-to—they bake evenly and look gorgeous on the table. If you don’t have one, a deep, oven-safe skillet works too.
• Wooden Spoon or Silicone Spatula: For stirring and scraping up those yummy bits at the bottom (don’t let ‘em go to waste!).
• Measuring Cups and Spoons: For accurate portions—especially with the cream and broth.
• Sharp Chef’s Knife and Cutting Board: Chopping chicken is way easier (and safer) with a sharp knife.
• Cheese Grater: Freshly grated cheese melts better and tastes richer—totally worth the extra minute.
• Oven Mitts: That pot gets hot coming out of the oven! Learned that one the hard way.

Equipment Tips: If you’re using a nonstick skillet, be careful with broiling (some coatings can’t take high heat). For easy cleanup, soak your pot right after dinner—baked-on cheese can be stubborn. If you’re on a budget, check thrift stores for Dutch ovens; mine cost $12 and has lasted years!

Preparation Method

1. Preheat Your Oven:
   • Set oven to 400°F (200°C). Position a rack in the center. This helps the cheesy top get nice and golden later on.
2. Season the Chicken:
   • Toss 2 large chicken breasts (about 1 lb/450 g), cut into bite-sized pieces, with 2 tablespoons Cajun seasoning. Make sure every piece gets a good coating. If you like things spicy, add a pinch of extra cayenne.
3. Sear the Chicken:
   • Heat 1 tablespoon olive oil in your large oven-safe pot over medium-high heat. Add chicken and let it cook until browned on all sides, about 4-5 minutes. Don’t worry if it’s not cooked through—it’ll finish baking later. Remove chicken to a plate and set aside.
4. Build the Sauce Base:
   • In the same pot (no need to clean out those flavorful bits!), add 4 cloves minced garlic. Sauté for 30 seconds until fragrant, then pour in 3 cups (710 ml) chicken broth and 1 1/2 cups (355 ml) heavy cream. Scrape up anything stuck to the bottom for extra flavor.
   • Stir in 1/2 teaspoon smoked paprika, 1/2 teaspoon onion powder, 1/2 teaspoon salt, 1/4 teaspoon black pepper, and 1/4 teaspoon crushed red pepper flakes if using.
5. Add the Pasta:
   • Pour in 12 ounces (340 g) uncooked penne pasta. Stir well to combine. The pasta should be mostly submerged—if not, add a splash more broth.
6. Simmer:
   • Bring to a gentle simmer over medium heat. Let it cook, uncovered, for 8-10 minutes, stirring occasionally so the pasta doesn’t stick. If it looks dry, add 1/4 cup (60 ml) extra broth. The sauce will thicken as the pasta cooks—don’t worry if it seems a bit soupy.
7. Return the Chicken & Add Cheese:
   • Stir the seared chicken (and any juices) back into the pot. Mix in 1 cup (100 g) grated Parmesan cheese until the sauce looks creamy and glossy. Taste and adjust seasoning—sometimes I sneak in a little more Cajun spice here!
8. Top & Bake:
   • Sprinkle 2 cups (200 g) shredded mozzarella evenly over the top. Transfer the pot, uncovered, to your preheated oven. Bake for 15-18 minutes, until the cheese is melted and bubbling.
   • If you crave a golden, crispy cheese crust, broil on high for 1-2 minutes at the end. Just watch closely—cheese can go from golden to burnt quickly!
9. Garnish & Serve:
   • Remove from oven (use those mitts!). Let the bake rest for 5 minutes; the sauce will thicken a bit, making serving easier.
   • Sprinkle with 2 tablespoons fresh parsley for color and freshness. Serve hot and enjoy every creamy, spicy bite!

Notes & Troubleshooting: If your sauce looks thin, it thickens as it cools. If it’s too thick, stir in a little warm broth. For extra color, add diced bell peppers with the garlic. If your chicken releases a lot of liquid while browning, drain off a bit before adding the cream—it helps keep the bake creamy, not watery.

Cooking Tips & Techniques

After making this One Pot Creamy Cajun Chicken Alfredo Bake dozens of times (and hearing feedback from friends and family), I’ve picked up a few tricks for nailing it every time.

• Brown the Chicken Well: Let those pieces get some color before removing from the pot. Browning adds so much flavor to the final dish. Don’t crowd the pan—work in batches if you need to.
• Don’t Overcook the Pasta: Since the pasta keeps cooking in the oven, aim for just barely al dente in the simmering step. Overcooked pasta turns mushy later (learned this the hard way during my third test batch!).
• Layer Flavors: Don’t skimp on the garlic, and use a bold Cajun seasoning. If you find the brand you’re using is mild, add an extra pinch.
• Keep an Eye on Liquid: Every pasta and pot combo behaves differently. If things look dry during simmering, add more broth. If it’s soupy, don’t panic—the oven thickens everything up.
• Cheese Timing: Add the mozzarella right before baking so it doesn’t dissolve into the sauce. I’ve tried mixing it in early, and you lose that melty topping.

One time, I got distracted and forgot to stir the pasta while it simmered—ended up with a layer stuck to the bottom. Now, I set a timer to remind myself to stir every 2-3 minutes. With practice, you’ll get a feel for your pot and how your stove handles simmering. The best tip? Taste as you go. If the sauce feels bland, add a pinch more Cajun seasoning or a squeeze of lemon right before serving. That little adjustment makes all the difference!

Variations & Adaptations

The beauty of this One Pot Creamy Cajun Chicken Alfredo Bake is how easy it is to make your own. Here are some of my favorite ways to switch it up:

• Low-Carb or Gluten-Free: Swap in chickpea pasta, lentil pasta, or your favorite gluten-free noodle. I’ve even tried zucchini noodles (zoodles)—just add them right before baking, since they cook fast.
• Seafood Cajun Alfredo: Use peeled shrimp instead of chicken. Sear them for just 1-2 minutes per side, then add back in at the end so they don’t overcook. You’ll get that classic New Orleans flavor in every bite.
• Veggie-Packed: Stir in a few handfuls of baby spinach, sliced mushrooms, or roasted red peppers before baking. Broccoli or asparagus work great too—just blanch them first so they stay tender.
• Dairy-Free: Use coconut cream and vegan cheese. The flavor changes a little, but it’s still rich and satisfying. My friend with a dairy allergy swears by this version!
• Spice Level: If you love heat, add extra crushed red pepper or a dash of hot sauce before serving. For a milder version, use less Cajun seasoning and skip the red pepper flakes.

One of my favorite personal twists? I sometimes use turkey sausage instead of chicken and add a handful of halved cherry tomatoes for a pop of sweetness. It’s a whole new flavor experience. Don’t be afraid to play around—this recipe is super forgiving, and you might find a new family favorite!

Serving & Storage Suggestions

This One Pot Creamy Cajun Chicken Alfredo Bake is best served piping hot, straight from the oven. The cheese pulls, the creamy sauce bubbles, and the aromas are just wild. I love bringing the pot right to the table and letting everyone scoop their own portion—family style at its finest.

If you’re looking to round out the meal, serve with a crisp green salad (I like arugula with lemon vinaigrette) or a side of garlic bread. A glass of chilled white wine or sweet iced tea pairs perfectly. For a bigger gathering, add roasted veggies or a simple fruit salad to keep things fresh.

Leftovers keep beautifully. Just let the bake cool, then cover and store in the fridge for up to 4 days. Reheat individual servings in the microwave with a splash of broth or cream to bring back the sauciness, or warm the whole pot in a low oven (covered) until hot. I’ve even frozen portions in airtight containers—they reheat best when thawed overnight in the fridge, then microwaved or baked. Honestly, I think the flavors get even better the next day as the spices mingle.
