About This Recipe

This 15-minute Creamy Cajun Chicken Pasta is built around a simple, high-impact idea: concentrate flavor early and let starch do the thickening. Browning diced chicken and softening red bell pepper in one pot creates those browned bits that lift the whole dish, while cooking the dry penne right in savory chicken broth absorbs seasoning into the pasta instead of leaving a thin sauce clinging to the surface. A splash of heavy cream and freshly grated Parmesan finish the pan with richness and a silky coating—the heat is lowered right when the dairy goes in so the sauce stays smooth rather than breaking.

It’s the kind of recipe that thrives on small self-contained choices: a bold Cajun rub that stands up to cream, a short pasta shape that traps sauce, and quick timing so nothing overcooks. Weeknight cooks, small families, and anyone who likes restaurant-style comfort without fuss will appreciate it. The dish is forgiving—swap proteins, add vegetables, or scale the spice to taste—yet it rewards little techniques (proper browning, scraping the fond, resting the sauce) that elevate it from pantry-level to genuinely satisfying.

Ingredients for 15-Minute Creamy Cajun Chicken Pasta (One-Pot Stovetop)

  • 1 lb Boneless skinless chicken breasts, cut into 1-inch pieces
  • 2 tbsp Cajun seasoning
  • 1 tbsp Olive oil
  • 1 cup Red bell pepper, diced (about 1 small)
  • 8 oz Dry penne pasta
  • 2 1/2 cups Low-sodium chicken broth
  • 1 cup Heavy cream
  • 1/2 cup Freshly grated Parmesan cheese

How to Make 15-Minute Creamy Cajun Chicken Pasta (One-Pot Stovetop)

  1. Step 1: Season and brown the chicken with pepper

    Toss the diced chicken with the Cajun seasoning until evenly coated. Heat the olive oil in a wide, deep skillet or Dutch oven over medium-high heat and add the chicken and diced red bell pepper; cook, stirring occasionally, until the chicken is browned on the edges and the pepper is softened, about 3–4 minutes.

    For this step

    • 1 lbBoneless skinless chicken breasts, cut into 1-inch pieces
    • 2 tbspCajun seasoning
    • 1 tbspOlive oil
    • 1 cupRed bell pepper, diced (about 1 small)
    Season and brown the chicken with pepper
  2. Step 2: Add pasta and broth, bring to a simmer

    Add the dry penne and chicken broth to the pot, scraping up any browned bits from the bottom. Bring to a boil, then reduce heat to medium-low and simmer uncovered, stirring occasionally, until the pasta is al dente and most of the liquid is absorbed, about 9–11 minutes (timing depends on pasta brand).

    For this step

    • 8 ozDry penne pasta
    • 2 1/2 cupsLow-sodium chicken broth
    Add pasta and broth, bring to a simmer
  3. Step 3: Make the creamy sauce

    Stir the heavy cream into the pot and raise the heat slightly to bring the mixture to a gentle simmer. Let it cook 1–2 minutes so the sauce thickens and coats the pasta, stirring to combine and prevent sticking.

    For this step

    • 1 cupHeavy cream
    Make the creamy sauce
  4. Step 4: Add Parmesan and finish the sauce

    Remove the pan from the heat and stir in the grated Parmesan until melted and the sauce is smooth. Taste and adjust seasoning with a pinch of salt, extra Cajun seasoning, or black pepper if desired.

    For this step

    • 1/2 cupFreshly grated Parmesan cheese
    Add Parmesan and finish the sauce
  5. Step 5: Rest and serve

    Let the pasta rest for 1–2 minutes so the sauce sets slightly, then divide into bowls. Serve hot, optionally garnished with extra Parmesan or chopped parsley if you like.

15-Minute Creamy Cajun Chicken Pasta (One-Pot Stovetop) Tips

Pat chicken dry

Wipe chicken pieces with paper towel before seasoning to promote faster browning and better fond for deeper flavor.

Scrape up the fond

After adding the broth, scrape the browned bits from the bottom of the pan with a spatula — that fond is concentrated flavor that seasons the sauce.

Stir pasta occasionally

Stir every few minutes while simmering so the penne cooks evenly and doesn’t clump or stick to the pot’s bottom.

Finish off heat

Remove the pan from direct heat before stirring in Parmesan to prevent graininess and keep the sauce silky.

Adjust sauce thickness

If sauce is too thin, simmer a minute longer uncovered; if too thick, stir in 1–2 tablespoons of hot water or broth to loosen it.

15-Minute Creamy Cajun Chicken Pasta (One-Pot Stovetop) Variations and Substitutions

Shrimp swap

Replace chicken with 1 lb peeled, deveined shrimp and reduce cook time—add shrimp after the pasta is nearly done and simmer until pink, about 2–3 minutes.

Vegetarian mushroom

Use 12 oz sliced cremini or portobello mushrooms (and double the bell pepper) for a hearty vegetarian version; add a splash of soy sauce when browning for extra umami.

Lighter cream option

Use half-and-half or a 1:1 mix of milk and a tablespoon of cornstarch for a lighter finish, but simmer gently and don’t boil to avoid separation.

Gluten-free or whole grain

Swap in your favorite gluten-free or whole-wheat penne and note that cooking time and liquid absorption will vary—check for doneness and add up to 1/2 cup extra broth if needed.

How to Store and Make 15-Minute Creamy Cajun Chicken Pasta (One-Pot Stovetop) Ahead

Store leftovers in an airtight container in the refrigerator for up to 3–4 days; the pasta will absorb sauce as it sits. Reheat gently on the stovetop over low heat with a splash of broth or cream to loosen the sauce, or microwave covered in short bursts, stirring between intervals. Freezing is possible but the cream sauce may change texture — consider freezing cooked chicken separately and assembling fresh if you want best quality.

What to Serve With 15-Minute Creamy Cajun Chicken Pasta (One-Pot Stovetop)

Serve with a crisp green salad dressed in lemon vinaigrette or a simple arugula salad to cut the richness, and pass extra grated Parmesan and lemon wedges at the table for brightness. A warm crusty baguette or garlic toast is great for mopping up the sauce; pair with an unoaked Chardonnay, a citrusy IPA, or an off-dry Riesling to complement the spice.

15-Minute Creamy Cajun Chicken Pasta (One-Pot Stovetop) FAQs

Can I use chicken thighs instead of breasts?

Yes — boneless skinless thighs add more moisture and flavor; cut into similar-sized pieces and brown a bit longer to render the fat, then proceed the same way.

Is the Cajun seasoning very spicy?

Heat levels vary by blend; start with 2 tablespoons as written and reduce to 1 tablespoon if you’re sensitive, or add more at the end to taste.

My sauce separated — how do I fix it?

Gently whisk in a small splash of hot broth or a teaspoon of cornstarch slurry over low heat to bring it back together, and avoid high heat when dairy is present.

Can I use pre-cooked chicken?

Yes — add diced cooked chicken after the pasta is done and warm through in the cream for 1–2 minutes so it doesn’t dry out.

Why cook pasta in broth instead of water?

Cooking pasta in broth seasons the pasta from the inside and the released starch helps create a naturally thickened, flavorful sauce without needing extra roux.

How do I make this less rich?

Use half-and-half or a lighter milk with a cornstarch slurry for thickening, and reduce the Parmesan to cut fat while keeping a creamy texture.
