Method
Preheat and season
- Preheat oven to 425F and place a sheet pan in the oven to preheat as well.
- Toss potatoes and carrots on the sheet pan with 3 tablespoons olive oil, garlic, Italian seasoning, salt, and black pepper until evenly coated.
First roast
- Roast for 20 minutes at 425F, until potatoes start to brown at the edges (look for light golden spots).
Add zucchini and finish
- Toss zucchini with the remaining olive oil, then add it to the pan and stir so everything sits in a single layer.
- Roast for 15 minutes more at 425F until potatoes are crispy and zucchini is tender (watch for browned zucchini edges).
Finish and serve
- Sprinkle the roasted vegetables with grated Parmesan and chopped fresh parsley right on the hot sheet pan so the cheese melts slightly.
- Serve immediately while the potatoes are crisp and the herbs look fresh.
Notes
For maximum crisping, avoid overcrowding the sheet pan—use a large pan or roast in two batches if needed. Store leftovers in an airtight container in the fridge for up to 3 days; reheat on a hot sheet pan in a 425F oven until warmed and the potatoes re-crisp. Freezing is not recommended because zucchini can turn watery after thawing. For a dairy-free swap, replace Parmesan with a nut-based Italian-style topping or finely grated nutritional yeast-style seasoning (use to taste).
