Irresistible Ingredients
- Chopped fresh parsley and extra Parmesan: sprinkle on at the end for pops of color and a little sharpness
- Extra salt and some more black pepper: toss these in at the last step to fine-tune your flavors
- Grated Parmesan: melts in the sauce for a salty tangy kick and makes it thicker; grate it yourself for the smoothest melt
- Heavy cream: gets you that ultra-creamy texture; don’t sub in anything lighter if you want it silky
- Fresh garlic: mince it fine and add for extra punchy savory flavor
- Bell peppers and a small onion: pick out a red and a green pepper for crunch and old-school color
- Chicken breasts, boneless and skinless: slice them thin so they cook quickly and don’t dry out; look for plump, moist pieces
- Butter and olive oil: frying in a mix brings a rich, velvety base
- Penne pasta: great for holding creamy sauce; bronze-cut has the best bite
- Salt and black pepper: always finish with a grind for depth
- Cayenne pepper: this is where the fire comes in – dial it back if you like less spice
- Oregano and thyme, dried: check they smell fresh before using – just rub a pinch and give it a sniff
- Onion powder: sweetens things up; find a fresh jar for best flavor
- Garlic powder: handy to layer extra taste; use a fine one so it blends in
- Paprika: brings smoky color with a sweet finish – Spanish style is my favorite
Simple Step Guide
- Add Final Touches:
- Ladle the creamy chicken pasta into bowls and finish with more Parmesan and fresh parsley. Serve it up hot and dig in!
- Mix Everything Together:
- Dump the cooked chicken and drained pasta into your skillet. Stir to coat with that spicy cream and fold in your Parmesan so it melts down. Check for seasoning and tweak it if you like.
- Thicken the Sauce:
- Slowly pour in your heavy cream and let things simmer on low, stirring here and there so the sauce gets glossy and thick – give it about five minutes.
- Throw in Garlic and More Spice:
- Drop in minced garlic and cook for a minute so it smells amazing. Sprinkle the skillet with the rest of your Cajun blend, and keep stirring so every veggie is coated well.
- Sauté Onions and Peppers:
- Keep your skillet over medium heat and toss in diced onions, red pepper, and green pepper. Stir around for about three to four minutes so they start softening and get a little sweet.
- Brown the Chicken:
- Over medium-high heat, melt your butter and warm the oil, then toss chicken in so it cooks fast and turns golden, about four to five minutes. Set it aside when the pieces are cooked through.
- Season the Chicken:
- Lay out your thin chicken strips and sprinkle well with the Cajun seasoning. Pat the blend on so it really sticks.
- Boil the Pasta:
- Set a big pot of water on the stove. Once it’s bubbling, salt it, add your penne, and cook just till it’s got bite left, then drain and set aside.
- Blend Spices:
- Add paprika, garlic and onion powder, thyme, oregano, cayenne, salt, and pepper into a bowl. Mix them nice and even, then set aside for later.

Red bell pepper is tops here, its sweetness perks up each forkful and reminds me of lively family nights. The first time my kid chopped peppers for this, she was thrilled with the colors and had to sneak a taste raw.
Keeping It Fresh
Chill leftovers in an airtight box once cooled — they’ll last up to three days. Heat them up with a splash of milk or cream so it stays saucy. You can freeze it, but the sauce gets thicker after defrosting and reheating.
Alternatives You Can Use
No penne handy? Try rotini or fettuccine. Swap in boneless thighs if you want richer chicken. For a lighter feel, use half and half and a squeeze of lemon for brightness. If you’re out of garlic, up the garlic powder by a notch instead.
How to Serve It Up
This makes a filling meal all on its own, but it’s so good with crisp salad or warm garlic bread to soak up the goodness. Steamed broccoli works too. Or go Southern with some corn muffins on the side.

How This Dish Came Together
Cajun seasoning mixes those soulful spicy flavors from Louisiana kitchens, where families have been combining French and Southern favorites forever. This pasta is a fun shake-up of creamy Italian with the bold heat of the South. My family’s both Cajun and Italian, so making this always turns dinnertime into a happy get-together.
Frequently Asked Questions

You’ll get a nice little heat from the seasonings, but you can add less or more chili kick, whatever you prefer.

Go easy on the heat when you’re stirring in cream and cheese, and keep whisking until it’s all silky, no lumps.

Bells and onions are classic, but you can totally toss in some spinach or mushrooms for extra flavor.
- → Is it good to make ahead?
It’s best hot and fresh, but if needed, chill any leftovers and reheat gently adding a splash of milk or cream to loosen it up.

Shrimp or turkey is awesome instead—just jazz it up with the same Cajun spices.
