Cooking Methods
🔥 Oven
Temperature: 425°F
Time: 15–20 minutes
Slice into 1/2-inch rounds or halve lengthwise. Toss with oil and seasoning. Roast until golden on the edges.
💨 Air Fryer
Temperature: 400°F
Time: 8–12 minutes
Slice into rounds or sticks. Toss with oil. Shake basket halfway. For breaded zucchini fries, use panko.
🔥 Grill
Temperature: 400°F
Time: 3–5 minutes
Halve lengthwise, brush with oil. Grill cut-side down for 3-4 minutes until marked, flip for 1-2 more.
🍳 Stovetop
Time: 4–6 minutes
Saute slices in oil or butter over medium-high heat. Do not crowd the pan or they will steam instead of sear.
Zucchini is 95% water. The number one mistake is crowding the pan, which traps steam and gives you soggy zucchini instead of golden, caramelized zucchini. Give the pieces space.

The Bottom Line
Zucchini is straightforward to cook when you know the time and temperature. Use the method that fits your equipment and schedule, and always let the food rest before cutting or serving. Resting allows juices to redistribute and carryover cooking to finish the job.
