Cajun Chicken Pasta – Ridiculously Creamy 40-Minute Dinner

Cajun Chicken Pasta is a one-pan dinner built on three things: a hard sear on the chicken, a proper Cajun spice bloom in fat, and a cream sauce finished off the heat. Get those right and the rest is timing.

I weigh everything because volume measures lie, especially with pasta and cream. The sauce breaks when it boils hard, so the pan comes off the burner before the cheese and cream go in.

Read the whole method once before you start. The dish moves fast after the chicken hits the pan, and there is no time to hunt for the paprika.

About the Ingredients

700 g (about 3 medium) boneless, skinless chicken breasts

Slice each breast horizontally into two thin cutlets so they cook evenly. Thighs work well here too and stay juicier if you tend to overcook chicken.

300 g (3 cups) dried penne or rigatoni

Ridged, tubular shapes hold the cream sauce best. Fusilli is a fine substitute if that is what you have.

2 tbsp (30 ml) olive oil

Use a neutral oil like canola if your olive oil smokes early. You want a hot pan without bitterness.

30 g (2 tbsp) unsalted butter

Buy butter with at least 82 percent fat; cheaper butter carries water and will thin the sauce.

1 medium yellow onion, about 150 g, diced

Yellow onion gives the sweetness the spice needs. Shallots are a sweeter, milder swap.

1 red bell pepper, about 150 g, sliced thin

Slice to the same thickness as the pasta so it eats cleanly. Frozen sliced peppers work without thawing.

3 cloves garlic, about 12 g, minced

Mince fine and add last; garlic burns in seconds. Jarred garlic is acceptable but tastes flatter.

2 tbsp (16 g) Cajun seasoning, salt-free blend

Salt-free lets you control the seasoning yourself. If yours contains salt, cut the added salt in half.

240 ml (1 cup) heavy cream, 36 percent fat

Do not substitute half-and-half; it curdles at sauce temperature. Full-fat coconut milk is the dairy-free option.

60 g (2/3 cup) grated Parmesan

Grate it yourself from a block; pre-shredded cheese is coated in starch and clumps. Pecorino is sharper but works.

400 ml (1 2/3 cups) reserved pasta water

Starchy water is your thinner. Never drain the pasta without scooping this out first.

8 g (1 1/2 tsp) fine sea salt, plus more for the pot

Season the pasta water like mild seawater. Kosher salt measures differently, so weigh it.

Tips & Tricks

Do Not Boil the Cream

Keep the sauce at a bare simmer, around 85 C (185 F). A hard boil makes the fat separate and the sauce turn grainy.

Season the Chicken Early

Salt and spice the cutlets 15 minutes before searing. The surface dries slightly and browns faster.

Undercook the Pasta by Two Minutes

It finishes in the sauce and absorbs flavor instead of water.

Reserve Water Before Draining

Once the pasta is drained, the starch is gone and the sauce cannot be adjusted.

Step-by-Step Instructions

1. Boil Salted Water

Bring 4 litres (4 quarts) of water with 10 g (2 tsp) salt to a rolling boil at 100 C (212 F). [Salting now seasons the pasta from the inside.]

2. Cook the Pasta

Add the penne and cook 9 minutes at a gentle boil. [It should be firm at the center, one minute short of the package time.] Scoop out 400 ml (1 2/3 cups) pasta water, then drain.

3. Season the Chicken

Pat the cutlets dry and coat both sides with 1 tbsp Cajun seasoning and 4 g (3/4 tsp) salt. [Dry meat browns; wet meat steams.] Let them sit 10 minutes.

4. Sear the Chicken

Heat the oil in a 30 cm (12 inch) skillet over medium-high heat to 190 C (375 F). Sear the cutlets 4 minutes per side. [They are done at 74 C (165 F) internal and golden brown at the edges.] Move to a board and rest.

5. Soften the Vegetables

Lower the heat to medium, add the butter, onion, and pepper, and cook 5 minutes. [The onion turns translucent and the pan smells sweet.] Add the garlic and remaining Cajun seasoning and stir 30 seconds.

6. Build the Sauce

Pour in the cream and 240 ml (1 cup) pasta water and simmer 3 minutes at 85 C (185 F). [The sauce coats a spoon and small bubbles ring the pan edge.]

7. Melt the Cheese

Turn off the heat and stir in the Parmesan until it disappears. [No grains should remain on the spoon.] Taste and adjust salt.

8. Combine and Serve

Add the pasta and sliced chicken with any resting juices and toss 1 minute. [The sauce should cling, not pool.] Loosen with pasta water if needed and serve at once.

Delicious Variations

Smoked Sausage Swap

Replace half the chicken with 250 g sliced andouille and brown it first for a deeper, smokier base.

Dairy-Free Version

Use full-fat coconut milk and nutritional yeast in place of cream and Parmesan; add them off the heat as well.

Extra Vegetable Load

Fold in 200 g blanched broccoli or sliced zucchini in the last two minutes of sauce simmering.
