FAQ’s with Great Tips…

1. Do we need to turn them over while roasting? No, it is not necessary.

2. Can we make them ahead? Yes, but they will soften as they cool down. You will need to reheat them in the oven. You can “Broil” them for 1 or 2 minutes to get them crispy again.

3. Do we need to peel the skins off? No, we prefer the skins left on with this recipe.

4. How many zucchini will we need? Because zucchini tends to shrink when it’s cooked, it is best to estimate: 1 large zucchini per person.

Both pecorino and parmesan cheese offer enough salt to the zucchini. However, everyone's taste is different, and if you taste one and feel you need to add some salt, then please do so.

    1. I hear you, Sherry! This is what it means: ” Broil” or Broiling uses only the upper heating element in your oven, applying high temps to the top of dishes to cook and crisp delicate foods or brown the top of already-cooked dishes. I hope this helps! 🙂
