This Cajun Alfredo with a fiery touch is what I turn to when I want cozy food that doesn’t feel boring. The homemade Cajun mix gives a hot punch to a dreamy, creamy sauce. Toss in juicy chicken, colorful peppers, and perfect pasta, and you’ve got a dish that’s exciting on a hectic evening. It’s my go-to when my crew’s hungry for something with a big flavor kick.

When this hits the table, my spicy food fans dive in and even the picky types want more. Mixing your own seasoning makes it easy to pick your perfect level of heat so everyone digs in happily.

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

→ How spicy does this Cajun dish get?

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

→ Can I swap the pasta shape?

Sure thing. Penne is great, but if you’ve got rigatoni or spaghetti, that’ll work just fine too.

→ How do I keep my sauce smooth?

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

→ Which veggies go nicely here?

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.

→ Got a substitute if I’m out of chicken?

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

→ Toppings (If You Want)

21 Extra Parmesan, grated, to sprinkle on top
22 Finely chopped fresh parsley for garnish

Instructions

Step 01

Try it and toss in a bit more salt or pepper if you want. Dish it up in bowls and throw over that chopped parsley and extra Parmesan if you're feeling fancy.

Step 02

Slide the cooked chicken back into the pan, dump in your drained penne, and give it a real good mix. Add the Parmesan and let it melt down nice and smooth.

Step 03

Pour in the heavy cream, let it start bubbling gently, and keep stirring now and then for about 5 minutes so the whole thing thickens just a touch.

Step 04

Drop in that minced garlic and let it sizzle for a minute. Dust over whatever Cajun mix you've got left.

Step 05

Use the same skillet to cook up the diced onion with those red and green bell peppers. Let 'em cook around 3-4 minutes so they get soft.

Step 06

Cover your chicken slices in about 1.5 teaspoons of the Cajun mix. Heat butter and olive oil in a big skillet on medium-high. Fry the chicken until each bit is browned and totally cooked. Set it aside and keep it warm.

Step 07

In a big pot with lots of salty water, cook your penne until it’s just barely tender (check the box directions if you want). Drain it and leave it aside for now.

Step 08

Grab a small bowl, toss together the paprika, garlic powder, onion powder, dried oregano, dried thyme, cayenne, black pepper, and salt. Set that aside.

Notes

  1. Toast the Cajun spices first in a dry pan if you want them to smell way more awesome.
  2. If you can, shred your own Parmesan so it melts perfectly into the sauce and tastes best.
