Creamy Cajun Chicken Penne Pasta

The first time my roommate made this Cajun chicken pasta, our tiny apartment smelled so incredible that neighbors actually knocked on the door to ask what was cooking. I've been making it ever since, tweaking the sauce until it hits that perfect balance between creamy comfort and gentle heat. Something about the way the spices bloom in the cream just makes people gather around the stove.

Last winter during a terrible snowstorm, I made this with whatever I had in the pantry. My friends who got stuck at my place still text me about that meal, asking when I'll make it again. Theres something about spicy, creamy pasta that just makes everything feel better.

Ingredients

• 2 large boneless skinless chicken breasts: Slice them horizontally so they cook faster and stay juicy
• 1 tablespoon Cajun seasoning plus 1 teaspoon: Divide this amount for coating chicken and seasoning the sauce
• 1 tablespoon olive oil: Use an oil with a high smoke point since were cooking over medium-high heat
• 350 g penne pasta: The ridges catch the sauce beautifully
• 2 tablespoons unsalted butter: This creates the silky base for our cream sauce
• 1 medium yellow onion: Finely diced so it melts into the sauce
• 3 cloves garlic: Minced fresh garlic makes a noticeable difference
• 1 red bell pepper and 1 yellow bell pepper: Thinly sliced for sweetness and color contrast
• 200 ml heavy cream: This is what makes the sauce rich and luxurious
• 100 ml chicken broth: Adds depth and helps balance the heavy cream
• 60 g grated Parmesan cheese: Freshly grated melts better than pre-shredded
• 2 tablespoons chopped fresh parsley: Brightens up the rich flavors

Instructions

Get the pasta going first:

Cook penne in salted boiling water until al dente then drain but save that pasta water

Prep your chicken:

Slice each breast horizontally and coat both sides generously with 1 tablespoon Cajun seasoning

Sear the chicken:

Heat olive oil in a large skillet over medium-high heat and cook chicken 4 to 5 minutes per side until golden

Rest and slice:

Let the chicken rest for 2 minutes before slicing into strips

Build the flavor base:

Melt butter in the same skillet then sauté onion for 2 minutes before adding garlic for 30 seconds

Add the peppers:

Stir in sliced bell peppers and cook 3 to 4 minutes until slightly softened

Create the sauce:

Pour in heavy cream and chicken broth with 1 teaspoon Cajun seasoning and bring to a gentle simmer

Finish the sauce:

Stir in Parmesan until melted then season with salt and pepper to taste

Bring it all together:

Add pasta and sliced chicken to the sauce tossing to coat and use pasta water if needed

My sister-in-law usually claims she doesnt like spicy food but she went back for thirds of this pasta. Watching people hesitantly try that first bite then immediately reach for another serving never gets old.

Making It Your Own

I've started adding a splash of white wine to the sauce sometimes and it brightens everything up beautifully. The acid cuts through the richness while still keeping that comforting creaminess we all love.

Vegetable Swaps

When bell peppers are out of season or just looking sad at the grocery store I've used zucchini or spinach instead. They dont add the same sweetness but they still work wonderfully with the Cajun spices.

Serving Suggestions

A crisp green salad with lemon vinaigrette cuts through the richness perfectly and makes the meal feel complete. I also like putting out extra Parmesan at the table because some people just really love cheese.

• Crusty garlic bread for soaking up extra sauce
• A cold glass of Sauvignon Blanc balances the heat
• Serve immediately while the sauce is at its silkiest

Theres something deeply satisfying about a recipe that looks impressive but comes together on a tired Tuesday evening. This pasta has saved more weeknight dinners than I can count.

Recipe FAQs

→ How spicy is this pasta dish?

The heat level is moderate and family-friendly. Cajun seasoning provides a gentle warmth rather than intense spice. For more kick, add cayenne pepper or diced jalapeños to the sauce.

→ Can I make this dish ahead of time?

Yes, you can prepare components in advance. Cook the pasta and chicken up to a day ahead, then reheat gently while making the fresh sauce. The dish actually develops more flavor as the ingredients meld together overnight.

→ What can I substitute for heavy cream?

Half-and-half works for a lighter version, though the sauce won't be quite as thick. Coconut cream creates a dairy-free alternative with subtle sweetness. For the richest results, stick with heavy cream.

→ How do I prevent the sauce from separating?

Keep heat at a gentle simmer—never boil vigorously. Add cheese off the heat or at very low temperature, stirring constantly. If sauce does separate, whisk in a splash of pasta water while warm to re-emulsify.

→ Can I use different pasta shapes?

Absolutely. Rotini, fusilli, or rigatoni work wonderfully as they catch the creamy sauce in their ridges and curves. Short pasta with texture holds the sauce better than smooth varieties like spaghetti.

→ Is there a gluten-free option?

Simply swap regular penne for your favorite gluten-free pasta—brown rice or corn-based varieties hold up well. Ensure your Cajun seasoning is certified gluten-free, as some blends contain wheat-based thickeners.
