Ingredients
Vegetables
-
1.5 lbs (680g) baby Yukon Gold or red potatoes, halved (quartered if larger)
-
3 large carrots (about 1 lb / 450g), peeled and cut into 1-inch thick sticks
-
1 medium zucchini (about ¾ lb / 340g), cut into 1-inch thick half-moons
-
1 medium yellow onion, cut into 1-inch chunks
Garlic Herb Seasoning
-
3 tablespoons extra-virgin olive oil
-
4-5 large garlic cloves, minced
-
1 tablespoon fresh rosemary, finely chopped
-
1 tablespoon fresh thyme leaves (or 1 tsp dried)
-
1 teaspoon dried oregano
-
¾ teaspoon kosher salt (plus more to taste)
-
½ teaspoon freshly ground black pepper
-
¼ teaspoon red pepper flakes (optional, for a hint of heat)
For Finishing
-
Zest of ½ a lemon (optional, but recommended)
-
2 tablespoons fresh parsley, finely chopped
Instructions
1. Prep and Preheat (Time: 10 mins | Intensity: Low)
Preheat your oven to 425°F (220°C). This high heat is crucial for achieving crispy, caramelized edges. While the oven heats, prepare all vegetables as directed, ensuring they are cut to roughly uniform sizes for even cooking. Pat the zucchini pieces dry with a paper towel to remove excess moisture. In a small bowl, combine the minced garlic, rosemary, thyme, oregano, salt, black pepper, and red pepper flakes.
2. Season the Vegetables (Time: 5 mins | Intensity: Low)
On a large, rimmed baking sheet, combine the potatoes, carrots, and onions. Drizzle with 2 tablespoons of the olive oil and toss to coat evenly. Sprinkle with about two-thirds of the garlic-herb seasoning mixture and toss again until the vegetables are well-coated. Important: Spread the vegetables out in a single layer, ensuring they aren’t crowded. This allows steam to escape and promotes roasting over steaming.
3. First Roast (Time: 25 mins | Intensity: Low – Hands Off)
Place the baking sheet in the preheated oven on the center rack. Roast, undisturbed, for 25 minutes. This initial roast will start to soften the potatoes and carrots and give them a head start.
4. Add the Zucchini (Time: 5 mins | Intensity: Low)
After 25 minutes, carefully remove the pan from the oven. The potatoes and carrots should be starting to brown at the edges. Add the zucchini pieces to the hot pan. Drizzle with the remaining 1 tablespoon of olive oil and sprinkle with the rest of the garlic-herb seasoning. Gently toss everything together, rearranging into a single layer once more.
5. Final Roast (Time: 10-15 mins | Intensity: Low – Hands Off)
Return the pan to the oven and roast for an additional 10-15 minutes, or until all vegetables are fork-tender, golden brown, and perfectly crisp in spots. The zucchini will be tender but still hold its shape.
6. Serve (Time: 2 mins | Intensity: Low)
Remove the pan from the oven. Immediately sprinkle with fresh parsley and lemon zest (if using). The residual heat will awaken their aromas. Taste and adjust with an extra pinch of salt if needed. Transfer to a serving dish and enjoy hot.
Chef’s Notes & Tips for Success
-
Cutting is Key: Uniform size = uniform cooking. Don’t skip the step of drying the zucchini—it prevents sogginess.
-
Pan Matters: Use a heavy, rimmed baking sheet. Avoid glass or ceramic pans, as they don’t promote browning as well. For the best crispiness, avoid lining with parchment; roasting directly on the metal pan is ideal.
-
Don’t Crowd the Pan: If your baking sheet looks packed, use two. Overcrowding steams the vegetables, making them soft instead of crispy.
-
Herb Flexibility: No fresh rosemary or thyme? Use 1 teaspoon each of dried. Tarragon, herbes de Provence, or Italian seasoning are also excellent substitutes.
-
Make it a Meal: Toss in some pre-cooked chickpeas for the last 10 minutes of roasting, or serve alongside roasted chicken, grilled fish, or pan-seared tofu for a complete, satisfying meal.
