Creamy Cajun Chicken Pasta (Spicy One-Pan Dinner)
Juicy cajun-spiced chicken strips tossed through penne in a rich, smoky cream sauce with peppers and a generous hit of Parmesan. One pan, 30 minutes, and genuinely restaurant-level results.
What is this dish?
Creamy Cajun chicken pasta is the kind of one-pan dinner that earns you compliments every single time. Chicken strips are coated in Cajun seasoning and seared until charred and smoky, then the same pan is used to build a cream and Parmesan sauce with peppers, garlic, and tomato paste. The pasta finishes cooking in the sauce, pasta water makes everything silky, and the whole thing comes together in 30 minutes. It's genuinely one of the best weeknight pasta dishes you can make.
Why you'll love it
It has the flavour of something you'd order at a restaurant — the smoky, spiced chicken, the sweet peppers, the tangy tomato-cream sauce — but it comes together with one pan and ingredients you likely already have. The heat is adjustable, it reheats well, and the whole family will eat it.
When to serve
Friday night dinner, date night, weeknight meal prep, or any time you want something impressive-looking with minimal fuss. Feeds 4 generously from one pan.
Quick tips
High heat for the chicken. Don't clean the pan. Reserve pasta water. Cook the tomato paste before adding liquid. Butter goes in at the end.
Cajun Seasoning
The whole flavour foundation of the dish. A good Cajun blend has smoked paprika, garlic, onion, cayenne, and dried herbs. Buy a quality blend or make your own — the difference between a good and a mediocre Cajun pasta often comes down to this single ingredient.
Tomato Paste
One tablespoon of tomato paste cooked out in the pan before the liquid goes in adds concentrated umami, slight sweetness, and a depth that makes the cream sauce taste like it's been simmering for hours.
Pasta Water
This is the chef's secret to sauces that cling perfectly to pasta. The starch leached from boiling pasta creates an emulsion with the cream and fat that no amount of extra cream can replicate. Always reserve a cup before draining.
Substitution Options
Replace chicken with prawns (shrimp) — season and sear for 2 minutes per side instead of 6–8. Use Italian sausage, andouille sausage, or even portobello mushrooms for a different version. Substitute cream with cream cheese thinned with pasta water for a tangier, slightly lighter sauce. Use gluten-free pasta and a gluten-free Cajun blend for a GF version.
Step-by-Step Instructions
Season and cook the chicken
In a bowl, toss the chicken strips with Cajun seasoning, smoked paprika, garlic powder, onion powder, cayenne, and salt until evenly coated. Heat olive oil in a large deep skillet or sauté pan over high heat. Add the chicken in a single layer and cook undisturbed for 3–4 minutes until deeply golden on one side, then flip and cook for another 2–3 minutes. The chicken should be cooked through with a charred, spiced crust. Remove to a plate and set aside.
Pro Tips:
- •Don't move the chicken for the first few minutes — you need the crust to form before flipping
- •Cook in batches if the pan is crowded — overcrowding causes steaming instead of searing
Cook the pasta
While the chicken rests, cook the pasta in a large pot of well-salted boiling water according to the packet instructions minus 2 minutes. It should be slightly underdone. Reserve at least 240ml (1 cup) of pasta water before draining — you'll need this. Drain and set aside.
Pro Tips:
- •Salty pasta water is essential — the water should taste like the sea
- •The pasta finishes cooking in the sauce so undercooking it at this stage is intentional
Sauté the peppers and garlic
In the same skillet you cooked the chicken (don't clean it — those browned bits are flavour), reduce the heat to medium-high. Add the sliced peppers and cook for 3–4 minutes until softened and slightly charred at the edges. Add the minced garlic and cook for 30 seconds until fragrant.
Pro Tips:
- •Cooking in the same unwashed pan picks up all the Cajun spice residue left by the chicken — don't waste it
- •Let the peppers sit without stirring for 60–90 seconds at a time to get some colour on them
Build the cream sauce
Add the tomato paste to the pan and stir it into the peppers and garlic. Cook for 1 minute to caramelise it slightly. Pour in the chicken stock and scrape up any browned bits from the bottom of the pan. Add the double cream, stir to combine, and bring to a gentle simmer. Cook for 3–4 minutes until the sauce reduces slightly and coats the back of a spoon.
Pro Tips:
- •Cooking the tomato paste for a full minute removes its raw, tinny flavour and adds sweetness
- •Don't boil the cream vigorously — a gentle simmer thickens it without splitting
Combine and finish
Add the drained pasta to the sauce and toss to coat. Add a ladleful of pasta water and stir — this is what makes the sauce silky and helps it cling to the pasta. Stir in the butter and Parmesan until both are fully incorporated. Slice the rested chicken and arrange over the pasta. Taste and adjust seasoning — more Cajun spice, more salt, more Parmesan.
Pro Tips:
- •The pasta water is not optional — the starch it contains is what binds the sauce to the pasta and gives it that glossy restaurant finish
- •Adding butter off the heat (or on very low heat) gives the sauce a luxurious, velvety quality
Chef's Tips
Techniques that separate good from great
Make your own Cajun blend
Store-bought Cajun seasoning varies wildly. A quick blend of 2 tsp smoked paprika, 1 tsp garlic powder, 1 tsp onion powder, ½ tsp cayenne, ½ tsp dried oregano, ½ tsp dried thyme, and ½ tsp black pepper gives you better control over the heat level.
Don't clean the pan between the chicken and the sauce
Those dark, Cajun-spiced bits stuck to the pan are pure concentrated flavour. The stock and cream deglaze them into the sauce when you add the liquid. Cleaning the pan between steps throws away the best part.
Slice the chicken on the diagonal
Slicing cooked chicken breast on a slight diagonal, against the grain, gives you longer, more visually appealing strips and a more tender texture than cutting straight across.
Nutrition Facts
Equipment Needed
- Large deep skillet or sauté pan
- Large pot for pasta
- Tongs
- Wooden spoon or spatula
Quick Tips
- Reserve the pasta water before draining — it's what makes the cream sauce silky and restaurant-quality rather than thick and heavy
- The Cajun spice crust on the chicken is everything — don't skip the high-heat sear and don't crowd the pan
- Taste at the end and adjust: more Cajun spice for heat, more Parmesan for saltiness and depth, pasta water to loosen
Recipe Variations
Different ways to make this dish your own
Cajun Shrimp Pasta
Replace the chicken with 400g of raw king prawns. Season with the same Cajun spice mix and cook for 2 minutes per side until pink. Everything else stays the same — just add them back in at the end rather than slicing.
Cajun Chicken Pasta Bake
Make the recipe up to the combining step, then pour everything into a baking dish, top with grated mozzarella and Parmesan, and bake at 190°C for 20 minutes until golden and bubbling.
Mild Cajun Chicken Pasta
Halve the cayenne and Cajun seasoning and add 1 teaspoon of smoked paprika in place of the spice. The result is a smoky, mildly spiced cream pasta suitable for anyone sensitive to heat.
Cajun Pasta with Sausage
Replace the chicken with sliced andouille or smoked sausage. Brown it in the pan first for 3–4 minutes, then proceed with the recipe as written. Andouille adds a deeper, smokier flavour than chicken.
What to Serve With
Perfect pairings to complete the meal
Garlic Bread
Thick slices of buttery garlic bread for sauce-scooping — the natural and correct accompaniment to any pasta with a cream sauce.
Simple Caesar Salad
The sharpness of a Caesar dressing cuts through the richness of the Cajun cream sauce and adds textural contrast.
Steamed Tenderstem Broccoli
Lightly steamed broccoli alongside or stirred into the pasta in the last minute of cooking adds green vegetables with no extra complexity.
Crusty Bread and Wine
A glass of chilled Chardonnay or Riesling pairs exceptionally well with creamy, spiced pasta. The slight sweetness of the wine tempers the Cajun heat.
Storage & Make-Ahead
Keep it fresh and plan ahead
Refrigerator
Store in an airtight container for up to 3 days. The pasta will absorb the sauce as it sits — add a splash of cream or stock when reheating.
Freezer
Cream-based pasta sauces can split when frozen — not recommended for freezing. The chicken can be frozen separately for up to 2 months.
Make-Ahead
Season and sear the chicken up to 2 days ahead. Make the sauce the day before and reheat gently, adding the cooked pasta fresh when serving.
Reheating
Reheat in a skillet over medium-low heat with 3–4 tablespoons of chicken stock or cream, stirring gently. Avoid high heat which can cause the cream sauce to split. The microwave works in 90-second bursts with a stir between each.
