Spiralize the zucchini: Use a spiralizer or a julienne peeler to make zoodles. Pat them dry with paper towels to remove excess moisture.
Prep your protein: If using chicken or another protein, have it cooked, seasoned lightly with salt and pepper, and ready to go.
Make the garlic base: Heat olive oil in a large skillet over medium. Add minced garlic and cook 30–60 seconds until fragrant, not browned.
Add red pepper flakes if using.
Wilt the zoodles: Add zoodles to the pan, toss with the garlic oil, and cook 2–3 minutes. You want them just tender, not soggy.
Build the sauce off heat: Turn off the heat. Stir in Greek yogurt, Parmesan, lemon zest, and 1 teaspoon lemon juice.
Toss until creamy. If it looks too thick, add 1–2 tablespoons warm water.
Add protein: Fold in chicken (or your choice of protein) until warmed through. Taste and adjust salt, pepper, and lemon.
Finish and serve: Top with parsley or basil and a final sprinkle of Parmesan.
Serve immediately while it’s silky and hot.
