Creamy Cajun Chicken Penne Pasta

The first time I made this pasta, my apartment smelled like a Cajun kitchen had taken over. I was experimenting with spice blends and ended up creating something that made my roommate abandon her homework to hover over the stove. That's when I knew this recipe was a keeper—anything that pulls people from other rooms deserves a permanent spot in the rotation.

Last winter, my friend Sarah came over feeling completely defeated by a terrible week at work. I put this pasta together while she sat at my counter, and by the time I slid that bowl in front of her, the combination of warm comfort food and spicy kick actually made her smile again. Sometimes food really is the simplest form of kindness.

Ingredients

• 2 large boneless, skinless chicken breasts: Slice them horizontally before seasoning so they cook faster and absorb more spice
• 1 tablespoon Cajun seasoning: Make your own blend if you can—store-bought varies wildly in heat level
• 350 g (12 oz) penne pasta: The ridges catch the sauce better than smooth pasta, so don't swap for spaghetti here
• 2 tablespoons unsalted butter: Use unsalted so you can control the seasoning properly
• 1 medium yellow onion: Finely diced so it melts into the sauce instead of staying chunky
• 3 cloves garlic: Fresh garlic matters—jarred stuff won't give you the same aromatic punch
• 1 red bell pepper and 1 yellow bell pepper: Thinly sliced for texture contrast against the soft pasta
• 200 ml (3/4 cup) heavy cream: Half-and-half works but won't give you that restaurant-style velvety finish
• 100 ml (1/3 cup) chicken broth: Homemade broth adds depth, but store-bought is perfectly fine
• 60 g (1/2 cup) grated Parmesan cheese: Grate it fresh from a block—pre-grated has anti-caking agents that make sauce grainy
• 2 tablespoons chopped fresh parsley: More than just garnish, it cuts through the richness with a fresh bite

Instructions

Get your pasta going first:

Cook penne in salted boiling water until al dente, then drain but reserve that pasta water—it's liquid gold for adjusting sauce consistency later

Prep the chicken while water heats:

Slice breasts horizontally through the middle, then coat both sides thoroughly with Cajun seasoning so every bite has that signature spice kick

Sear the chicken:

Heat olive oil in a large skillet over medium-high and cook chicken 4 to 5 minutes per side until golden and cooked through—let it rest 2 minutes before slicing so juices stay inside

Build the flavor base:

In the same skillet, melt butter and sauté onion 2 minutes, add garlic for 30 seconds, then toss in bell peppers and cook until slightly softened

Create the sauce:

Pour in cream and broth with that extra teaspoon of Cajun seasoning, bring to a gentle simmer, then stir in Parmesan until melted and slightly thickened

Bring it all together:

Add drained pasta and sliced chicken to the sauce, tossing to coat evenly—use reserved pasta water if sauce needs loosening

Serve it up:

Plate immediately while it's piping hot, topping with fresh parsley and extra Parmesan if you're feeling generous

Save to Pinterest

This pasta became my go-to dinner whenever life feels overwhelming or when friends need cheering up. Something about spicy comfort food just makes everything seem more manageable, even if it's just for the twenty minutes it takes to finish a bowl.

Getting the Heat Right

Cajun seasoning intensity varies wildly between brands, so taste your sauce before adding the second teaspoon. I once made a batch that had everyone reaching for milk, and learned that you can always add heat but you can't take it away.

Make-Ahead Friendly

The sauce actually develops more flavor if made ahead and reheated, but cook the pasta fresh. I've tried meal-prepping the complete dish and the pasta soaks up all the sauce, leaving you with a dry, disappointing lunch.

Pairing Ideas

The creaminess calls for something acidic to cut through—think crisp white wine or even just a simple green salad with vinaigrette. Heavy food needs light companions to feel balanced.

• A glass of Sauvignon Blanc balances the richness beautifully
• Cold beer works surprisingly well with spicy dishes
• Keep extra Parmesan at the table for those who love it extra salty

This pasta has saved countless weeknight dinners and turned ordinary Tuesdays into something worth celebrating. Hope it finds its way into your regular rotation too.

Recipe FAQs

→ How spicy is this pasta dish?

The Cajun seasoning provides a moderate kick that's flavorful without being overwhelming. If you prefer more heat, add cayenne pepper or sliced jalapeños. For a milder version, reduce the Cajun seasoning to half.

→ Can I make this dish ahead of time?

Yes, you can prepare the components ahead. Cook the pasta and chicken separately, then store in the refrigerator. Reheat gently with a splash of cream or pasta water to restore the sauce's creamy texture before serving.

→ 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 milk adds a subtle sweetness while maintaining creaminess. For a dairy-free option, use cashew cream or almond milk blended with a bit of cornstarch.

→ How do I prevent the sauce from separating?

Keep the heat at a gentle simmer rather than a rolling boil. Stir constantly when adding the cheese, and avoid overheating once combined. If reheating, do so slowly over low heat while stirring frequently.

→ Can I use different pasta shapes?

Fusilli, rotini, or rigatoni work beautifully with this sauce—their nooks and crannies capture the creamy coating. Longer shapes like fettuccine also work well. Just adjust cooking time according to package directions.

→ What vegetables can I add?

Sliced mushrooms, spinach, or diced zucchini complement the flavors nicely. Add them along with the bell peppers so they cook through. For extra crunch, toss in some broccoli florets or asparagus pieces.
