Ingredients for Easy Creamy Cajun Chicken Pasta Recipe in 30 Minutes
Exact amounts are in the printable recipe card below — here's what you'll need at a glance.
Main Ingredients
- 1 lb boneless skinless chicken breasts, cut into bite-size pieces
- 1 tablespoon cornstarch
- 2 tablespoons olive oil, divided
- 1 tablespoon unsalted butter
- 8 oz penne pasta
- 1 small yellow onion, finely diced
- 1 red bell pepper, sliced
- 3 cloves garlic, minced
- 1 ½ cups heavy cream
- ½ cup low-sodium chicken broth
- ½ cup grated Parmesan cheese
- 2 tablespoons tomato paste
Seasonings & Flavors
- 2 teaspoons Cajun seasoning, divided
- 1 teaspoon smoked paprika, divided
- ½ teaspoon dried oregano
- ½ teaspoon kosher salt, plus more to taste
- ¼ teaspoon black pepper
- ¼ teaspoon cayenne pepper (optional)
Optional Toppings
- (Optional) Chopped fresh parsley
- (Optional) Sliced green onions
- (Optional) Extra grated Parmesan cheese
- (Optional) A squeeze of fresh lemon juice
Ingredient Notes
- Chicken breast: Cut into even bite-size pieces so they cook at the same rate. The cornstarch coating seals in moisture and helps browning. If you use thighs, add 1–2 minutes of cooking time.
- Heavy cream: High fat content prevents the sauce from curdling under gentle heat. Half-and-half can be used but reduces richness and increases splitting risk.
- Tomato paste: Adds body and a sweet-tart base that balances the cream. It must be cooked briefly to remove raw tin flavor.
- Parmesan cheese: Use freshly grated, not pre-shredded. Pre-shredded contains cellulose that prevents smooth melting and can make the sauce gritty.
- Cajun seasoning: Different brands vary in salt and heat. Taste before adding extra salt, especially if your blend includes salt.
How to Make Easy Creamy Cajun Chicken Pasta Recipe in 30 Minutes Step by Step
Season and coat chicken
In a medium bowl, toss chicken pieces with 1 teaspoon Cajun seasoning, ½ teaspoon smoked paprika, salt, and pepper. Sprinkle cornstarch over the chicken and toss again until each piece is lightly coated. Watch for dry spots; the cornstarch should cover all surfaces.
Sear chicken
Heat 1 tablespoon olive oil in a 12-inch skillet over medium-high heat. Add chicken in a single layer, leaving space between pieces. Cook 4–5 minutes, turning once, until golden brown on both sides and internal temperature reaches 165°F. If the skillet is crowded, chicken steams instead of browning, so work in batches if needed. Transfer to a plate.
Cook pasta
Bring a large pot of salted water to a boil. Add penne and cook 8–10 minutes until just al dente. Reserve 1 cup of pasta water before draining. The pasta should still have a slight bite because it will finish in the sauce.
Sauté vegetables
In the same skillet, melt butter with remaining 1 tablespoon olive oil over medium heat. Add onion and bell pepper. Cook 4–5 minutes, stirring occasionally, until softened and edges begin to caramelize. Add garlic and cook 30 seconds, just until fragrant. Watch carefully; garlic burns quickly and turns bitter.
Build the sauce
Stir in tomato paste, remaining 1 teaspoon Cajun seasoning, remaining ½ teaspoon smoked paprika, oregano, and cayenne. Cook 1 minute to bloom the spices, stirring constantly to prevent scorching. Pour in chicken broth and scrape up any browned bits from the skillet bottom. Simmer 2–3 minutes until slightly reduced.
Finish with cream and cheese
Reduce heat to low. Stir in heavy cream. Simmer gently 3–4 minutes, do not boil, until the sauce thickens enough to coat the back of a spoon. Remove the skillet from heat. Stir in Parmesan a little at a time until melted and smooth. If the sauce gets too hot, it can split into oil and solids.
Combine and serve
Add cooked pasta and seared chicken back to the skillet. Toss to coat, adding reserved pasta water a splash at a time if the sauce is too thick. Taste and adjust salt and pepper. Serve immediately with your choice of toppings.
Pro Tips for the Best Easy Creamy Cajun Chicken Pasta Recipe in 30 Minutes
- Ingredient prep: Pat the chicken pieces completely dry with paper towels before coating with cornstarch. Any extra moisture steams the meat instead of browning it.
- Common mistake and fix: Boiling the cream sauce is the #1 mistake. High heat breaks the fat-protein emulsion, causing a greasy, curdled mess. Keep the sauce at a low simmer and remove the skillet from heat before adding Parmesan. If your sauce does split, whisk in a splash of warm chicken broth off heat to bring it back together.
- Timing: Start the pasta water before you sear the chicken. This way the pasta finishes cooking while the sauce simmers, and the entire dish comes together hot.
- Flavor enhancement: Bloom the tomato paste and spices in the skillet for a full minute before adding liquid. This releases fat-soluble flavor compounds and removes any raw metallic taste from the paste.
Storing and Reheating Easy Creamy Cajun Chicken Pasta Recipe in 30 Minutes
Refrigerator Storage
Store leftovers in an airtight glass container for up to 3 days. The sauce may thicken as it chills; add a splash of milk when reheating.
Freezing Easy Creamy Cajun Chicken Pasta Recipe in 30 Minutes
Freeze in a freezer-safe zip-top bag or container for up to 2 months. Remove as much air as possible before sealing to prevent freezer burn. The cream sauce may separate slightly after thawing, but whisking while reheating helps.
Reheating in the Oven
Preheat oven to 325°F. Place pasta in an oven-safe dish, add 2–3 tablespoons of milk or broth, cover with foil, and heat 15–20 minutes until warmed through.
Reheating in the Microwave
Microwave at 50% power in 45-second intervals, stirring between each. Add a splash of milk and cover with a damp paper towel to prevent the pasta from drying out.
Make Ahead
You can dice the chicken, chop vegetables, and measure all spices up to 24 hours ahead. Store them separately in the fridge. Do not cook the pasta or make the cream sauce ahead, as both degrade in texture when held.

Recipe Notes
- Chef tip: Always grate Parmesan fresh from a block. Pre-grated cheese contains anti-caking agents that prevent a silky sauce and can clump when melted.
- Best substitution: Swap heavy cream for full-fat canned coconut milk for a dairy-free version. The sauce will be slightly thinner, so simmer 2 extra minutes to thicken.
- Make-ahead: Prep all vegetables and measure spices up to a day in advance. Save cooking the pasta and building the sauce for just before serving to keep textures fresh.
- Scaling: Double the recipe using a 6-quart Dutch oven or wide skillet. Keep the sauce on low heat and cook chicken in two batches to avoid steaming.
- Troubleshooting: If your cream sauce curdles, remove the pan from heat immediately. Whisk in 2–3 tablespoons of warm chicken broth until the sauce comes back together, then serve right away.

Frequently Asked Questions about Easy Creamy Cajun Chicken Pasta Recipe in 30 Minutes
How do I keep Easy Creamy Cajun Chicken Pasta from getting a curdled sauce?
The sauce curdles when it boils or when Parmesan is added over high heat. Keep the burner on low once cream goes in and never let the liquid bubble rapidly. Remove the skillet from heat before stirring in cheese. If curdling happens, whisk in warm broth off heat to re-emulsify.
Can I make this creamy Cajun pasta ahead of time?
Yes, but only partially. Dice chicken and vegetables up to 24 hours ahead and store in separate containers. Do not cook the pasta or cream sauce in advance. The pasta absorbs too much sauce when refrigerated together, and the cream can separate when reheated.
What can I substitute for heavy cream in this recipe?
Full-fat coconut milk works as a dairy-free option, though the sauce will be slightly thinner. Half-and-half is acceptable but increases the risk of curdling because it has less fat. Do not use low-fat milk, as it will definitely split under heat.
Is this Cajun chicken pasta a good Mardi Gras dinner idea?
Yes, it is perfect for a Mardi Gras celebration because the spices and smoky flavor echo Louisiana cuisine. Serve it with a side of cornbread and a simple green salad. The bright bell pepper and Cajun seasoning bring festive color and heat to the table.
How do I store and reheat leftover Easy Creamy Cajun Chicken Pasta?
Refrigerate in an airtight container for up to 3 days. Reheat gently on the stove or microwave at 50% power with a splash of milk. Stir often to keep the sauce from separating. For best texture, reheat only what you will eat at one time.
