Recipe FAQs

What vegetables work best for roasting in this dish?

Zucchini, red bell pepper, and red onion are ideal due to their sweetness and texture after roasting, but seasonal veggies like eggplant or mushrooms can also be used.

How do I get the bread crispy without burning the cheese?

Cook the sandwich over medium heat, allowing the bread to toast slowly while the cheese melts evenly inside.

Can I substitute mozzarella with another cheese?

Fresh mozzarella offers a creamy melt that complements the vegetables well, but mild cheeses like provolone or fontina can be alternatives.

What is the purpose of the balsamic glaze?

The balsamic glaze adds a tangy sweetness that enhances the flavors and provides a nice contrast to the creamy cheese and roasted vegetables.

How long should the vegetables be roasted?

Roast the vegetables for 18–20 minutes, flipping halfway, until they are tender and lightly caramelized.
