Expert Tips and Tricks
Here are some expert tips to make this easy side dish:
Uniform slicing - For even cooking, try to slice the zucchini into uniform thickness. Aim for slices that are about ½-inch thick. Thick slices will retain more moisture, and thin slices will be crispier.
Don't Overcrowd the Pan - Arrange the zucchini slices in a single layer on the baking sheet. Avoid overcrowding, as this can result in uneven cooking and steaming instead of baking which will make soggy zucchini.
Reduce Food Waste - This is an easy way to use up a lot of zucchini from the garden or farmer's market. Feel free to double the recipe and eat as the perfect snack over the week.

Frequently Asked Questions
Absolutely! Adding other vegetables to the baking sheet along with the zucchini slices is a fantastic idea to create a colorful and flavorful medley of roasted veggies. Some good choices would be: bell peppers, red onion, cherry tomatoes, mushrooms, broccoli, asparagus, or carrots.
Whether to peel the zucchini or not is a matter of personal preference. Zucchini skin is edible and adds a beautiful green color to the dish, making it more visually appealing. If you prefer a smoother and more tender texture, you can peel the zucchini before baking. Removing the skin will result in a softer zucchini slice without any chewiness from the skin.
These baked zucchini slices are best served fresh from the oven. This is when they will be the crispiest. However, if you choose to reheat them and eat them at a later time, reheating them in the oven or under the broiler will help to bring back some of the crispy texture.

Here are storage and reheating instructions for this simple recipe.
