1-First Step: Mise en Place and Pasta Prep Start by cubing 1 lb boneless chicken breasts into bite-sized pieces for even cooking. Mince 6 garlic cloves and grate 1.5 cups parmesan fresh to prevent graininess. Bring a large pot of salted water to a rolling boil. Add 12 oz fettuccine or linguine and cook until al dente, about 8-10 minutes. Drain, reserving 1/2 cup pasta water for sauce adjustment, and set pasta aside. This step ensures pasta doesn’t overcook and sticks to the chicken.

2-Second Step: Cook the Chicken Heat a large skillet over medium-high heat. Melt 4 tbsp butter until foaming. Add the cubed chicken, season with salt, pepper, and 1 tsp Italian seasoning. Cook 5-7 minutes, stirring occasionally, until chicken turns golden brown and reaches 165°F internally. Remove chicken to a plate if needed, but for one-pot ease, keep it in. Browning builds flavor through Maillard reaction, key for standout taste.

3-Third Step: Sauté Garlic and Build Sauce Base Lower heat to medium. Add minced garlic to the skillet with chicken drippings and butter. Stir 30-60 seconds until fragrant but not browned, avoiding bitterness. Pour in 1 cup chicken broth to deglaze, scraping up browned bits. This captures all flavors. Then stir in 1 cup heavy cream. Bring to a gentle simmer for 4-5 minutes, letting it reduce and thicken slightly. Medium heat prevents curdling.

4-Fourth Step: Create the Creamy Sauce Reduce heat to low. Gradually whisk in 1.5 cups grated parmesan cheese, adding in handfuls while stirring constantly. The sauce will turn silky and glossy. If too thick, add reserved pasta water 1 tbsp at a time. Simmer 2 minutes until smooth. Taste and adjust salt, pepper, or Italian seasoning. For optional add-ins like spinach, stir in 2 cups fresh spinach until wilted or 1/4 cup chopped sun-dried tomatoes for tang.

5-Fifth Step: Combine and Toss Add drained pasta directly to the skillet. Toss gently 1-2 minutes to coat every noodle in sauce. The chicken integrates fully here. If using one-pot method, cook pasta in the broth from step three: after garlic, add 4 cups broth, pasta, and simmer 8-10 minutes until absorbed.

6-Final Step: Finishing Touches and Serving Remove from heat. Garnish with chopped fresh parsley and extra parmesan shavings. Serve hot with crusty bread or a simple salad. Pairs nicely with a refreshing drink for complete meals. Pro tip: Fresh ingredients shine, so grate cheese at home.
