Before you start
Before beginning the cooking process, gather and prepare all your ingredients to ensure a smooth workflow. Measure out the Cajun seasoning, heavy cream, and grated Parmesan cheese. Mince the fresh garlic cloves and chop the fresh herbs.
Trim any excess fat from the chicken breasts and pat them completely dry with paper towels so the seasoning adheres properly and creates a crispy crust. Fill a large pot with water for the spaghetti and set it on the stove.
Ingredients at a glance (7)
- 2 boneless, skinless chicken breasts
- 2 tbsp Cajun seasoning
- 8 oz spaghetti
- 4 cloves garlic, minced
- 1 cup heavy cream
- 1/2 cup grated Parmesan cheese
- 2 tbsp chopped fresh herbs
Instructions
Searing the Cajun Chicken
- Sear the Cajun ChickenSeason the chicken breasts generously on both sides with the Cajun seasoning. Heat a large skillet over medium-high heat. Add the seasoned chicken directly to the hot pan and cook for 6 to 8 minutes per side, until a deep golden-brown, blackened crust forms and the internal temperature reaches 165 degrees Fahrenheit (74 degrees Celsius). Transfer the cooked chicken to a cutting board and let it rest for 5 minutes before slicing.Look for The chicken should have a dark, crispy crust and feel firm to the touch.Safe temperature 165°F (74°C) internal temperature (poultry)Tip Do not move the chicken around too much in the pan to ensure a beautiful sear.
At the end of this phase, the chicken breasts should have a deep, golden-brown, almost blackened crust on both sides.
When pressed gently, the meat should feel firm, and a meat thermometer inserted into the thickest part must read 165 degrees Fahrenheit. The kitchen will fill with a rich, smoky, and spicy aroma from the seared Cajun spices.
Creating the Garlic Parmesan Sauce
- Boil the SpaghettiMeanwhile, bring a large pot of salted water to a boil. Add the spaghetti and cook according to the package instructions until it is al dente. Drain the pasta in a colander, reserving one cup of the starchy cooking water to help build the sauce later.Look for The pasta should be tender but still retain a slight bite in the center.Tip Salting the pasta water generously flavors the noodles from the inside out.
- Sauté the GarlicIn the same skillet used for the chicken, add the minced garlic and a splash of the reserved pasta water over medium heat. Cook for 1 minute, stirring constantly to scrape up the flavorful browned bits and spices left behind by the chicken.Look for The garlic should turn soft and highly fragrant without browning.Tip Using the pasta water lifts the caramelized spices directly into the sauce base.
- Simmer the Cream and ParmesanPour the heavy cream into the skillet and bring it to a gentle simmer. Reduce the heat to low, then gradually whisk in the grated Parmesan cheese. Stir continuously for 2 to 3 minutes until the cheese is completely melted and the sauce is smooth and slightly thickened.Look for The sauce should easily coat the back of a spoon.Tip Add the cheese slowly on low heat to prevent the sauce from separating.
The garlic should be soft and highly fragrant without being browned or burnt. Once the heavy cream and Parmesan are incorporated, the sauce will bubble gently and thicken to a smooth, velvety consistency that easily coats the back of a spoon. The aroma will transition from sharp garlic to a rich, savory, and cheesy scent.
Combining the Pasta and Plating
- Combine and ServeAdd the drained spaghetti to the skillet, tossing gently to coat the noodles thoroughly in the creamy sauce. If the sauce is too thick, stir in a few more tablespoons of the reserved pasta water. Slice the rested Cajun chicken breast and serve it alongside the creamy spaghetti, garnished with the chopped fresh herbs.Look for The pasta should be glossy and thoroughly coated in the warm sauce.Tip Slice the chicken at an angle for a beautiful restaurant-style presentation.
The spaghetti should be completely coated in the glossy, creamy sauce, with rising steam carrying the fragrance of garlic and cheese. The sliced chicken should show a beautiful contrast between the dark, seasoned exterior and the juicy, white interior. Garnish with vibrant green herbs to complete the presentation.
Common mistakes
One common mistake is burning the garlic, which introduces a bitter flavor that ruins the entire cream sauce; always keep the heat at medium-low and stir constantly during this quick step.
Another error is adding the Parmesan cheese to a boiling sauce, which causes the proteins to clump and results in a grainy texture. Finally, slicing the chicken immediately after cooking will cause all the juices to run out, leaving the meat dry; always let it rest.
How to tell it’s done
The chicken is fully cooked and safe to consume when the internal temperature reaches 165 degrees Fahrenheit (74 degrees Celsius) on an instant-read meat thermometer.
The spaghetti is perfectly cooked when it is al dente, meaning it is tender but still has a slight firmness when bitten. The sauce is ready when it is thick enough to coat the noodles beautifully without pooling at the bottom of the plate.
