Frequently Asked Questions
Can I use frozen vegetables instead of fresh?
Yes, but be sure to thaw and pat them dry first. Frozen veggies tend to release more moisture, which can prevent them from roasting properly. You may also need to adjust the cooking time slightly.
What’s the best way to reheat roasted vegetables?
For the best texture, reheat them in a 375°F oven for about 10 minutes. You can also use an air fryer for a crispier finish. Avoid microwaving, as it can make them soggy.
Can I make this recipe ahead of time?
Absolutely. You can prep the veggies and seasoning mix a day in advance. Store them separately in the fridge and combine just before roasting. This saves time and keeps everything fresh.
Is this recipe gluten-free?
Yes, this recipe is naturally gluten-free. Just double-check your balsamic vinegar and Parmesan cheese labels to ensure they don’t contain any hidden gluten ingredients.
What other seasonings can I use?
Feel free to experiment! Smoked paprika, cumin, curry powder, or even lemon zest can add a new twist. Just be sure not to overpower the natural flavors of the vegetables.
