Ingredients

Ingredients

  • 2 large boneless, skinless chicken breasts, sliced into thin strips
  • 12 oz spaghetti
  • 1 tbsp olive oil
  • 4 tbsp salted butter, divided
  • 5 cloves garlic, minced, divided
  • 1.5 tsp Cajun seasoning
  • 1 tsp smoked paprika
  • 1 tsp salt
  • 1/8 tsp freshly cracked black pepper or to taste
  • 0.5 cup grated Parmesan, for crusting the chicken
  • 1.5 cups heavy cream
  • 3/4 cup low-sodium chicken broth
  • 1 cup shredded mozzarella
  • 1 cup shredded sharp cheddar
  • 3/4 cup grated Parmesan, for sauce
  • 2 oz cream cheese, softened to room temperature
  • 1/2 tsp Italian seasoning
  • 1/2 tsp dried basil
  • 1/4 tsp crushed red pepper flakes optional, for extra heat
  • Fresh chopped parsley, for garnish

Instructions

  • Bring a large pot of salted water to a boil. Cook the spaghetti until just al dente (about 8–9 minutes, check package instructions). Drain, toss lightly with 1 tbsp olive oil to prevent sticking, and set aside.
  • Pat the chicken strips dry with paper towels. In a bowl, mix Cajun seasoning, smoked paprika, salt, and black pepper. Season the chicken evenly.
  • Press 1/2 cup grated Parmesan onto both sides of the seasoned chicken to form a light crust.
  • Heat a large skillet over medium-high heat. Add 1 tbsp olive oil (if using additional) and 2 tbsp butter. When butter is shimmering, add the chicken strips in a single layer. Sear until golden and cooked through, about 3–4 minutes per side depending on thickness.
  • During the last 30–60 seconds of searing, add half of the minced garlic to the skillet and sauté briefly to bloom the garlic without burning.
  • Remove the chicken to a plate and tent loosely with foil to keep warm.
  • Reduce heat to medium, add the remaining 2 tbsp butter to the skillet, and add the rest of the minced garlic. Sauté until fragrant, about 30 seconds.
  • Pour in the heavy cream and chicken broth. Bring to a gentle simmer, stirring to scrape up any browned bits from the pan.
  • Add the softened cream cheese and whisk until fully incorporated and smooth.
  • Stir in mozzarella, sharp cheddar, and 3/4 cup grated Parmesan. Continue stirring until the cheeses melt and the sauce is thick and creamy.
  • Add Italian seasoning, dried basil, and crushed red pepper flakes (if using). Taste and adjust seasoning with salt and pepper.
  • Add the cooked spaghetti to the sauce and toss gently to coat. Let the pasta sit in the sauce for 1–2 minutes to absorb flavors.
  • Plate the spaghetti, top with the Parmesan-crusted chicken strips, and sprinkle with fresh chopped parsley to finish.

Notes

Store leftovers in an airtight container for up to 3 days. Reheat gently on the stovetop over low heat with a splash of chicken broth or milk to revive the sauce.
