Prep the zoodles: Spiralize the zucchinis using a spiralizer or julienne peeler.
Sprinkle lightly with salt and set aside in a colander for 10–15 minutes to draw out moisture. Pat dry before cooking.
Season the chicken: Slice chicken into cutlets or bite-size pieces. Season with salt, pepper, garlic powder, and Italian seasoning.
Sear the chicken: Heat 1 tablespoon olive oil in a large skillet over medium-high heat.
Add chicken and cook until golden and just cooked through, about 4–6 minutes total depending on size. Remove to a plate and tent loosely with foil.
Build the sauce base: Lower heat to medium. Add the remaining olive oil and the butter.
Stir in the minced garlic and cook 30–60 seconds, until fragrant but not browned.
Add the cream: Pour in the heavy cream and bring to a gentle simmer. Stir often for 2–3 minutes to slightly thicken.
Melt in the cheese: Reduce heat to low. Gradually whisk in the Parmesan until smooth and silky.
If the sauce seems too thick, add a splash of water or more cream; if too thin, simmer another minute.
Season to taste: Add a pinch of red pepper flakes, more salt and pepper as needed, and optional lemon zest for brightness.
Return the chicken: Add the cooked chicken (and any juices) back into the pan. Toss to coat and warm through for 1–2 minutes.
Cook the zoodles: In a separate skillet, quickly sauté the zoodles in a touch of butter or olive oil over medium heat for 1–2 minutes. You want them just tender, not soft.
Combine and serve: Fold the zoodles into the Alfredo and chicken, or plate zoodles first and spoon the sauce over top.
Finish with extra Parmesan and parsley.
