Ingredients

Scale
  • 1 lb boneless, skinless chicken breasts (cut into bite-sized pieces)
  • 23 tablespoons Cajun seasoning
  • 2 tablespoons olive oil
  • 2 tablespoons unsalted butter
  • 34 cloves garlic, minced
  • 1 cup roasted red peppers (about 2 peppers, sliced, from a jar or homemade, patted dry)
  • 3 cups low sodium chicken broth
  • 12 oz pasta (penne, fettuccine, or rigatoni)
  • 1 cup heavy cream
  • 1 cup freshly grated Parmesan cheese
  • Salt & pepper, to taste
  • Fresh parsley, chopped (for garnish, optional)

Instructions

  1. Toss chicken pieces with Cajun seasoning until evenly coated. Let sit for 5 minutes.
  2. Heat olive oil in a large, deep skillet or Dutch oven over medium-high heat. Add chicken in a single layer and cook for 3–4 minutes, stirring occasionally, until browned but not cooked through. Transfer chicken to a bowl and set aside.
  3. Reduce heat to medium. Add butter to the same pot. Once melted, stir in garlic and cook for 30 seconds until fragrant. Add roasted red peppers and sauté for another minute.
  4. Pour in chicken broth, scraping up any browned bits from the bottom. Bring to a gentle simmer.
  5. Stir in pasta, ensuring it is mostly submerged. Bring to a boil, then reduce heat to medium-low. Cover and cook for 10–12 minutes, stirring every 2–3 minutes, until pasta is al dente and most liquid is absorbed.
  6. Uncover and return chicken (plus any juices) to the pot. Pour in heavy cream and stir well. Simmer uncovered for 2–3 minutes, until chicken is cooked through and sauce starts to thicken.
  7. Turn off the heat. Gradually stir in Parmesan cheese until melted and sauce is creamy. Taste and add salt and pepper as needed.
  8. Garnish with fresh parsley and extra Parmesan if desired. Serve immediately.

Notes

For gluten-free, use gluten-free pasta. For dairy-free, substitute coconut cream and vegan Parmesan. Stir pasta frequently to prevent sticking. If sauce thickens too much, add a splash of broth or cream. Adjust Cajun seasoning to taste. Garnish with lemon juice or extra veggies for variation.
