Prep the zucchini: Spiralize the zucchinis into noodles. Place them on a clean kitchen towel, sprinkle lightly with salt, and let sit 10 minutes to release moisture.
Pat dry.
Season the chicken: Slice chicken breasts in half horizontally to make cutlets. Season both sides with salt, pepper, and a pinch of Italian seasoning.
Sear the chicken: Heat 1 tablespoon butter and the olive oil in a large skillet over medium-high heat. Cook chicken 3–4 minutes per side until golden and cooked through.
Transfer to a plate to rest, then slice.
Make the Alfredo base: Reduce heat to medium. Add remaining butter and the garlic. Sauté 30–60 seconds until fragrant, not browned.
Add cream: Pour in heavy cream and bring to a gentle simmer.
Whisk in Parmesan until melted and smooth. If you want extra thickness, whisk in cream cheese.
Season the sauce: Add salt, pepper, and a pinch of red pepper flakes if using. A small squeeze of lemon can brighten the flavors.
Warm the chicken: Stir sliced chicken into the sauce and let it simmer 1–2 minutes to coat.
Cook the zoodles: Add zucchini noodles to the skillet and toss gently.
Cook 1–3 minutes until just tender. Do not overcook or they’ll get watery.
Serve: Taste and adjust seasoning. Top with extra Parmesan and a sprinkle of herbs.
