Step-by-Step Instructions
- Prep Zoodles: Spiralize zucchinis. Pat with paper towels to remove extra moisture.

- Add Cheese: Stir in Parmesan, salt, and pepper until smooth and creamy.
- Cook Zoodles: Add zucchini noodles to skillet; toss 2–3 minutes until just tender but not mushy.
- Finish: Top with more Parmesan and parsley. Serve immediately (with chicken if using).
Tips for Success
- Don’t overcook zoodles—keep them slightly firm for best “pasta” texture.
- Dry zucchini noodles well to prevent a watery sauce.
- Add chicken or shrimp for a protein boost and make it a main dish.
