  • Parmesan cheese: nutty and salty, fresh-grated makes it melt so much better than bags
  • Heavy cream: the rich base for everything grab the best quality you can find
  • Garlic: chopped small for a kick of sharp flavor use plump, heavy cloves
  • Red and green bell peppers: sweet crunch and color find firm and shiny ones
  • Onion: diced for a sweet base solid and glossy onions work best
  • Chicken breasts: slice thin so they cook evenly bright pink and plump is what you want
  • Olive oil and unsalted butter: together they bring the flavor and creaminess use your favorite butter
  • Penne pasta: sturdy, great for holding sauce cook until just al dente for best bite
  • Black pepper and salt: use fresh-ground when you can for the biggest taste
  • Cayenne pepper: spicy heat classic Cajun goes up or down depending on how hot you like it
  • Dried oregano and dried thyme: earthy herbs crush in your hand a little for extra fragrance
  • Garlic powder and onion powder: boost that savory backbone fresher powders have the most punch
  • Paprika: smoky, red, and a must for Cajun flavor go for a deep hue

Simple Cooking Steps

Add Toppings and Serve:
Ladle the hot pasta into bowls, sprinkle with fresh chopped parsley, and a bit more cheese. Eat while it’s creamy and hot!
Bring Everything Together:
Put the chicken back in along with your drained penne. Gently toss everything so each bite gets coated with sauce. Stir in your cheese till it gets smooth. If it clumps, splash in some pasta water.
Let the Sauce Thicken:
Lower the heat and pour in your heavy cream. Scrape up the brown bits so it’s extra flavorful. Simmer on low for 5 minutes, just enough for the sauce to get creamy but not boil over.
Boost the Spicy Layer:
Scatter in your garlic, stir around for about a minute till it smells awesome. Add the extra Cajun mix and toss everything so it’s well-coated and spicy.
Soften Veggies:
Use that same pan, medium heat, and cook up onions and peppers. Give it a few stirs, about 4 minutes, until the onions look glassy and peppers are soft but still bright.
Brown Up Chicken:
In a big skillet, get the oil and butter sizzling on medium-high. Toss your sliced chicken with a heaping spoon of Cajun spice. Lay the chicken in—don’t crowd it—and let it brown 2-3 minutes a side. Move to a plate but keep the tasty pan juices.
Boil and Drain Pasta:
Get a big pot bubbling with salted water. Toss in your penne and cook per the package until just al dente. Drain and set aside.
Mix Cajun Spices:
In a small bowl, stir together the paprika, powders, herbs, cayenne, salt, and pepper. Break up lumps with your fingers so it mixes even. Set aside for later.

Freshly grated Parmesan always melts way better than the pre-bagged stuff. My kids' favorite thing is twirling up every last noodle to grab all that spicy creamy sauce after school.

How to Store Leftovers

Pop any extra pasta in a sealed container, then stash it in the fridge for up to three days. When you reheat, toss in a little milk or water and warm it gently on the stove. Keeps it nice and creamy.

Swap It Up

No penne? You can totally use rotini or fettuccine instead. No chicken? Try shrimp or turkey pieces, just keep an eye they don't overcook and dry out.

Tasty Sides

This filling pasta loves a crisp green salad with zingy dressing or some steamed broccoli. Garlic bread is always a crowd-pleaser since it picks up all the saucy goodness.

How This Pasta Got Its Kick

While Alfredo has Italian roots, mixing in Cajun seasoning gives things a deep Louisiana touch and rounds out the creamy classic with some heat. Dishes like this blend traditions and make dinnertime feel fresh and homey.

FAQs About the Recipe

→ Is this super spicy or more mild?

The heat really depends on how heavy you go with the cayenne in your Cajun mix. You can turn it up or down, whatever you like best.

→ What if I don’t have penne?

No worries! Penne’s great, but fettuccine, rigatoni, or your favorite pasta will work just fine with the creamy sauce and chicken.

→ How do I make sure the sauce stays velvety?

If you keep the cream from getting too hot and add the parmesan off the stove, your sauce should stay smooth and not clump up.

→ Besides bell pepper, what other veggies can I add?

Onions and garlic really pump up the flavor. You can toss in mushrooms or fresh spinach, too, if that’s your thing.

→ How should I warm up leftovers?

Just reheat gently on low and stir in a splash of milk or cream to bring the sauce back to life.

→ How do I do this without any dairy?

Swap the cream for your favorite dairy-free option and try vegan parmesan. You’ll get a similar creamy richness!

→ To Serve (Optional)

21 Extra grated Parmesan on top, if you want
22 A handful of chopped fresh parsley for the finish

Step-by-Step Guide

Step 01

Give it a taste and see if it needs more salt or pepper. Spoon into bowls, and if you're feeling fancy, toss on some extra Parmesan or chopped parsley.

Step 02

Put the chicken you already cooked back in and then toss in that penne you drained. Stir things up. Make sure everything's hugged by that sauce. Mix in the Parmesan until it's all melted together.

Step 03

Bring in the heavy cream and let it gently bubble. Keep it going for about 5 minutes, stirring now and then, until things get a bit thick.

Step 04

Now add your garlic and let it go for maybe a minute until it smells awesome. Sprinkle in the rest of that Cajun mix.

Step 05

Toss your onion plus both bell peppers into that same pan. Let them cook about 3 or 4 minutes until they're nice and tender.

Step 06

Heat up the butter and oil in your biggest skillet over medium-high. Drop in the chicken and cook it till it's brown and done all the way. Scoop it out and set aside for later.

Step 07

Cover your chicken slices with about 1 1/2 teaspoons of your homemade Cajun blend.

Step 08

Fill up a big pot with water, toss in plenty of salt, and get it boiling. Throw in the penne and cook by the package until it's got a little bite left. Drain the pasta and set it to the side.

Step 09

Grab a small bowl and mix together all those spices for the Cajun seasoning. When that's done, leave it nearby.

Additional Notes

  1. If you want an extra smoky kick, toss your Cajun blend in a dry skillet for a minute or two before using.
  2. You’ll get the smoothest melt if you grate your own Parmesan fresh.
