Add fettuccine and cook according to package instructions (typically 10–12 minutes).
8 oz fettuccine
Drain and set aside.
Cook the Chicken:
Heat a cast iron skillet over medium-high heat and add olive oil.
2 tbsp olive oil
Season the whole chicken breasts with salt, pepper, garlic powder, and smoked paprika on both sides.
2 lbs chicken breast, 1 tsp salt, ½ tsp black pepper, ½ tsp garlic powder, ½ tsp smoked paprika
Sear for 4–5 minutes per side, until golden brown. Reduce heat to medium-low and cover for another 5 minutes, or until the chicken reaches 165°F internal temp. You will likely need to do this in multiple batches or use multiple pans!
Remove from the skillet, let it rest for 5 minutes, then cut into cubes and set aside.
Make the Alfredo Sauce:
In a large jumbo cooker, melt butter over medium heat.
2 tbsp unsalted butter
Add minced garlic and sauté for 30 seconds until fragrant.
4 cloves garlic
Pour in heavy cream, then add salt, black pepper, Italian seasoning, and red pepper flakes (if using).
1½ cups heavy cream, ½ tsp salt, ½ tsp black pepper, ½ tsp Italian seasoning, ¼ tsp red pepper flakes
Bring to a gentle simmer, then stir in Parmesan cheese. Let cook for 2–3 minutes, stirring constantly, until the sauce is smooth and thick.
1 cup grated Parmesan cheese
Combine & Serve:
Add the cooked fettuccine to the Alfredo sauce, tossing until fully coated.
Gently stir in the cubed chicken and let everything heat through for 2 minutes.
Divide into meal prep containers. Garnish with extra Parmesan and fresh parsley before serving.
