🍽️ Why 350°F Is Great for Zucchini
Zucchini contains over 90% water, so high heat helps evaporate moisture while keeping the flesh tender.
At 350°F, you get:
- Even cooking
- Soft yet firm texture
- Slight caramelization
- Less risk of burning
- Perfect base for cheese or breadcrumbs
🔪 How to Prepare Zucchini for Oven Cooking
1. Wash and dry well
Any moisture left on the surface can cause steaming instead of roasting.
2. Cut evenly
Uniform slices = even cooking.
3. Season generously
Zucchini is mild, so seasoning matters.
4. Add a little oil
Oil helps browning and prevents drying out.
5. Don’t overcrowd the pan
Zucchini needs space to roast, not steam.

- Salt & pepper
- Garlic powder

🕒 How to Tell When Zucchini Is Done
Perfectly cooked zucchini will be:
- Soft but still holding its shape
- Lightly golden on the edges
- Fork-tender (but not mushy)

If it bends or collapses easily—it’s overcooked.
📚 Tips to Stop Zucchini From Getting Mushy
Zucchini cooks fast and releases water, so follow these tips:
✔ Don’t slice too thin (½-inch is ideal)
Thin slices = soggy.
✔ Use a hot pan
Preheating the baking sheet helps.
✔ Salt the zucchini before baking
This pulls out excess water.
Dry with paper towels before baking.
✔ Leave space between pieces
Crowding = steaming.
✔ Don’t add too much oil
1–2 tbsp is enough.
✔ Broil briefly for crispiness
Just 1–2 minutes.
