Cut for even cooking
Keep zucchini slices fairly thick. Very thin slices can soften before the peppers are ready, making it harder to turn everything without breaking it. Leave a little root attached to each onion wedge so the layers stay together.
Cherry tomatoes can remain whole. Use a rimmed pan because they may split and release liquid. Do not use a flat cookie sheet that lets hot juices run into the oven.
Give the pan some space
A single layer exposes more surface to the oven's heat. Vegetables piled into a deep baking dish tend to steam in their own juices. If using two pans, rotate their positions halfway through and start checking early; ovens do not heat every shelf equally.
Dry the washed vegetables before adding oil. Extra water on their surfaces increases steaming and can dilute the seasoning. The oil should lightly coat the pieces without collecting in deep pools.


Add feta after checking tenderness
Test a pepper strip and a zucchini piece with a fork before scattering the cheese. If they are still firm, give them more time first. Browning alone does not tell you whether a thick pepper is tender.
Feta softens and warms but behaves differently from mozzarella. Crumbling it over the pan distributes small salty bites; there is no need to crush the tomatoes or stir the dish into a sauce.
Save leftovers safely
Transfer leftovers to shallow covered containers and refrigerate within 2 hours, or within 1 hour above 90°F. Keep at 40°F or colder and use within 3 days. Reheat only the portion needed to 165°F. Zucchini releases more moisture during storage, so expect a softer texture when reheated.
