Method
Prepare the potatoes
- Rinse and halve potatoes as needed, bring a medium pot of salted water to a boil, add potatoes and parboil for 8 minutes; drain well in a colander and let steam-dry for 1–2 minutes.
Make the herb oil
- Whisk together 2 tablespoons olive oil, 1 tablespoon minced garlic, rosemary, thyme, 1 teaspoon kosher salt, and 1/2 teaspoon pepper in a small bowl.
Roast the heartiest pieces
- Preheat oven to 425°F; toss the drained potatoes with two-thirds of the herb oil and spread cut-side down on a lined or lightly oiled rimmed sheet pan; roast for 15 minutes.
Add sturdier vegetables
- Toss carrots and red onion with the remaining herb oil and arrange around the potatoes, return pan to oven and roast 12 minutes more.
Finish with tender vegetables
- Toss zucchini and broccoli with 1 tablespoon olive oil and a pinch of salt, add to the pan and gently toss so vegetables are in one layer; roast 8–10 minutes until potatoes are browned and vegetables have caramelized edges.
- If desired, broil 1–2 minutes to deepen color—watch constantly to avoid burning.
Serve
- Remove from oven, drizzle lemon juice if using, sprinkle optional Parmesan or red pepper flakes, and serve hot.
Notes
Parboiling the potatoes ensures tender centers and crisp exteriors; do not overcrowd the pan—use two pans if needed. Add quick-cooking vegetables like zucchini and bell peppers late in the roast to prevent sogginess. Store leftovers refrigerated up to 4 days and re-crisp in a 400°F oven for 10–12 minutes.
