Italian Baked Vegetables au Gratin
This is a classic Italian way to make everyday vegetables more flavorful: seasonal vegetables are dressed with olive oil, herbs and breadcrumbs, and baked until tender underneath and golden on top. It's an easy recipe that showcases the Italian love of letting fresh ingredients shine.
What Are Verdure Gratinate al Forno?
In Italian cooking, gratinare means creating a golden crust on the surface of food. For vegetables, this is typically achieved with a mixture of breadcrumbs, olive oil, herbs, and sometimes grated cheese. Unlike rich, cream-based gratins, Italian verdure gratinate al forno are lighter and allow the natural flavor of the vegetables to take center stage.

How to Make Italian Baked Vegetables au Gratin
Prepare the vegetables
Wash and cut the vegetables into even pieces so they cook evenly. Arrange on a parchment-lined baking sheet, slightly overlapping.
Season the vegetables
Drizzle the vegetables with olive oil, sprinkle salt, pepper, and dried oregano. Top with Italian-style breadcrumbs, fresh chopped basil and/or parsley.
Bake
Bake until the vegetables are tender and the top is golden and crispy.
Pro Tip
Make a gratin topping: combine breadcrumbs, Parmigiano, parsley, and olive oil until the mixture is lightly moistened and crumbly. Then, sprinkle the breadcrumb mixture evenly over the vegetables before baking.
Tips for Success
- Cut vegetables into similar sizes and thickness for even cooking.
- Don't skip the olive oil - it helps the breadcrumb topping become golden and flavorful.
- Add the breadcrumb topping generously but avoid making it too thick.
- If adding, use freshly grated Parmigiano for the best flavor.
- Bake uncovered so the topping can crisp.
Storage and Reheating
Store leftovers in an airtight container in the refrigerator. Reheat in the oven to help the topping crisp again.
FAQ
Can I prepare Italian Baked Vegetables au Gratin ahead of time?

How do I keep the topping crispy?
Bake uncovered and reheat in the oven rather than the microwave.
