Spiralize the zucchini. Use a spiralizer, julienne peeler, or the thin blade of a mandoline.
Aim for noodle-like strands about spaghetti thickness. If the strands are very long, cut them in half with kitchen scissors.
Salt and rest. Toss the zoodles with 1/2 teaspoon salt in a colander. Let them sit for 10–15 minutes to draw out excess water.
This step keeps them from turning watery in the pan.
Pat dry. Gently squeeze the zoodles, then lay them on a clean kitchen towel or paper towels and pat them dry. Removing moisture is the key to great texture.
Prep aromatics. Mince or thinly slice garlic. Zest the lemon first, then cut it and set aside the juice.
Have red pepper flakes ready if using.
Sauté the garlic. Heat olive oil in a large skillet over medium heat. Add garlic and cook 30–60 seconds until fragrant, not browned. Add red pepper flakes now if you like a little heat.
Cook the zoodles fast. Add the dried zucchini noodles.
Toss with tongs for 2–3 minutes until just tender with a slight bite. Do not overcook. You want them bright green and flexible, not limp.
Finish with brightness. Turn off the heat.
Add lemon zest, a squeeze of lemon juice, and black pepper. Toss. Taste and add a pinch of salt if needed.
Add extras (optional). Fold in halved cherry tomatoes for sweetness, sprinkle with Parmesan or a dairy-free alternative, and top with fresh basil or parsley.
If you’re using cooked shrimp, chicken, or chickpeas, warm them through in the last minute.
Serve immediately. Zucchini noodles are best hot from the pan. Plate and garnish with a final drizzle of olive oil and a light shower of cheese or herbs.
