Begin by cutting the chicken into uniform, bite-sized pieces. Mince the garlic finely and grate the Parmesan cheese if not pre-grated.
Marinating the Chicken:
In a bowl, combine chicken pieces with olive oil, minced garlic, dried thyme (or rosemary), salt, and pepper.
Let the chicken marinate for at least 30 minutes (up to 2 hours in the refrigerator) for enhanced flavor.
Cooking the Pasta:
Bring a large pot of salted water to a boil. Add the pasta and cook according to package instructions until al dente.
Reserve 1 cup of pasta water and then drain the pasta thoroughly.
Sautéing the Chicken:
In a large skillet, heat a splash of olive oil over medium-high heat.
Cook the marinated chicken in batches to avoid overcrowding. Sauté for 5-7 minutes per side until golden brown and cooked through (internal temperature should reach 165°F).
Once done, remove the chicken and keep it warm.
Creating the Creamy Garlic Parmesan Sauce:
In the same skillet, lower the heat and add the butter.
Once melted, add the remaining minced garlic and sauté briefly until fragrant.
Pour in the heavy cream and stir continuously.
Gradually add the grated Parmesan cheese, stirring to form a smooth and cohesive sauce.
If the sauce thickens too much, slowly add some of the reserved pasta water to adjust the consistency.
Season with salt, pepper, and optional red pepper flakes.
Combining the Ingredients:
Return the sautéed chicken to the skillet, then add the cooked pasta.
Toss everything together until the pasta is evenly coated with the garlic parmesan sauce and the chicken is well distributed.
Finishing Touches:
Garnish with freshly chopped basil or parsley.
For the baked variation, transfer the mixture to a baking dish, sprinkle mozzarella cheese on top, and bake in a preheated oven at 375°F for 10-15 minutes until the cheese is melted and bubbly.
Serving:
Serve immediately while hot. For added flavor, provide lemon wedges on the side for those who prefer a lemon garlic parmesan chicken twist.
