Garlic Herb Roasted Potatoes, Carrots and Zucchini
Golden potatoes, sweet roasted carrots and tender zucchini make a simple side dish that works with almost any dinner. Olive oil, garlic and a handful of herbs bring everything together, while a hot oven gives the vegetables those delicious browned edges.
The trick is giving the potatoes and carrots a head start. Zucchini cooks much faster, so adding everything to the pan at once can leave you with soft zucchini before the potatoes are ready. This recipe adds the zucchini partway through and the fresh garlic near the end for better texture and flavor.

Ingredients
- 1½ pounds baby potatoes or Yukon Gold potatoes, cut into ¾-inch pieces
- 1 pound carrots, peeled and cut into ½-inch-thick diagonal slices; halve thick carrots lengthwise first
- 2 medium zucchini, about 1 pound total, cut into 1-inch chunks or thick half-moons
- 4 tablespoons olive oil, divided
- 4 garlic cloves, finely minced
- 1 teaspoon dried thyme
- 1 teaspoon dried rosemary, crushed between your fingers
- ½ teaspoon dried oregano
- 1 teaspoon fine sea salt, divided, plus more to taste
- ½ teaspoon freshly ground black pepper, divided
- 2 tablespoons chopped fresh parsley
- 1–2 teaspoons fresh lemon juice, optional
- ¼ cup freshly grated Parmesan, optional, for serving
Ingredient Notes
Potatoes: Baby gold potatoes and Yukon Gold potatoes have creamy centers and roast well. Leave the skins on after scrubbing. Cut larger potatoes down so the pieces are roughly the same size.
Carrots: Thick carrot pieces need longer in the oven. Keep them smaller than the zucchini so they become tender alongside the potatoes.
Zucchini: Choose firm, medium zucchini and cut it into substantial pieces. Thin slices soften quickly and are more likely to fall apart when tossed.
Garlic: Fresh garlic goes in near the end. Finely minced garlic can burn during a full roasting cycle at this temperature.
How to Make Garlic Herb Roasted Potatoes, Carrots and Zucchini
1. Heat the oven and prepare the pans
Preheat the oven to 425°F (220°C). Set racks in the upper and lower thirds of the oven. Lightly oil two large rimmed baking sheets, each about 13 by 18 inches.
Dry the washed vegetables thoroughly. Surface moisture encourages steaming and makes browning harder.
2. Season the potatoes and carrots
Place the potatoes and carrots in a large bowl. Toss with 2½ tablespoons olive oil, the thyme, rosemary, oregano, ¾ teaspoon salt and ¼ teaspoon pepper.
Divide between the baking sheets and spread in a single layer, leaving space between pieces. Put potato cut sides against the pan where possible.
3. Give the root vegetables a head start
Roast for 25 minutes. Flip the vegetables, swap the pans between racks and rotate them front to back.
The potatoes and carrots should be starting to brown but may still feel firm in the centers.
4. Add the zucchini
Toss the zucchini with 1 tablespoon olive oil, the remaining ¼ teaspoon salt and the remaining ¼ teaspoon pepper just before adding it to the pans.
Divide the zucchini between the pans, keeping everything in a single layer. Roast for another 10–15 minutes.
5. Add the garlic and finish roasting
Mix the minced garlic with the remaining ½ tablespoon olive oil. Gently toss it through the vegetables and roast for another 5–10 minutes.
The vegetables are ready when a fork slides easily into the potatoes and carrots, the edges are browned, and the zucchini is tender but still holds its shape. Total roasting time will be about 40–50 minutes, depending on your oven and the size of the pieces.
If one pan finishes first, take it out while the other continues cooking. If the zucchini is ready before the root vegetables, transfer it to a serving bowl and let the potatoes and carrots finish roasting.
6. Finish and serve
Sprinkle with fresh parsley. Add a small squeeze of lemon juice if you like, taste and adjust the seasoning. Finish with Parmesan if using, and serve warm.
Tips for Better Roasted Vegetables
Use enough pan space. This is a generous batch. Two large baking sheets help the vegetables roast instead of sitting in a crowded, steamy pile.
Keep the zucchini chunky. Larger pieces are easier to roast until tender without turning mushy.
Season zucchini just before roasting. Salting it far ahead draws out moisture that can collect in the bowl and on the pan.
Watch the garlic. Add it late and distribute it through the vegetables. Small bits left on bare metal can brown quickly.
Check tenderness, not just the timer. Potato variety, pan material and the accuracy of your oven all affect cooking time.
Serve soon after roasting. The edges soften as the vegetables sit, especially when covered.
Easy Variations
- Parmesan garlic vegetables: Add grated Parmesan just before serving for a salty finish.
- A little heat: Toss in a pinch of crushed red pepper with the dried herbs.
- Lemon herb vegetables: Finish with lemon zest as well as a little lemon juice.
- Fresh herbs: Replace the dried herbs with about 1 tablespoon chopped fresh rosemary and 1 tablespoon fresh thyme leaves. Stir delicate herbs such as parsley or basil in after roasting.
- Yellow squash: Substitute yellow summer squash for the zucchini and add it at the same stage.
What to Serve With Roasted Potatoes, Carrots and Zucchini
These vegetables pair well with roast chicken, pork tenderloin, baked salmon, meatloaf or grilled steak. They also work alongside a lentil loaf or chickpea patties for a meatless dinner.
Because potatoes are already included, you can keep the rest of the meal simple: add your main dish and dinner is ready. A little gravy, tzatziki or lemon yogurt sauce on the side is another easy way to change the flavor.
Make-Ahead Tips
For the best texture, roast the vegetables shortly before serving. You can peel and cut the carrots a day ahead and refrigerate them in a covered container. Cut potatoes can be kept submerged in cold water in the refrigerator overnight; drain and dry them very thoroughly before seasoning.
Keep prepped zucchini separate and season it just before it goes into the oven. Measure the dried herbs ahead to make dinner preparation quicker.
Storage and Reheating
Refrigerate leftovers in a covered container within 2 hours and use within 3–4 days.
To reheat, spread the vegetables on a baking sheet and warm at 400°F (200°C) for about 10–15 minutes, until hot throughout. A microwave works for convenience, though the vegetables will be softer.
Freezing is possible, but the zucchini will become noticeably softer after thawing. Refrigerating and enjoying the leftovers within a few days gives better texture.
Frequently Asked Questions
Can I roast all three vegetables at the same time?
You can, but they will not finish with the same texture. Potatoes and carrots need longer than zucchini. Giving the root vegetables a head start is the more reliable approach.
Do I need to peel the potatoes?
No. Scrub baby potatoes or Yukon Gold potatoes well and leave the skins on. Peel them if that is your preference.
Why are my roasted vegetables soggy?
The most common causes are crowded pans, wet vegetables and zucchini cut too thin. Dry everything well, leave space on the pans and add thick zucchini pieces later in the cooking time.
Can I use garlic powder instead of fresh garlic?
Yes. Replace the fresh garlic with 1 teaspoon garlic powder. Toss about two-thirds with the potatoes and carrots and the rest with the zucchini. Divide all 4 tablespoons of oil between those two batches, since you will not need to reserve any for fresh garlic.
Can I halve the recipe?
Yes. Halve all ingredients and use one large rimmed baking sheet on the middle rack. Keep the same oven temperature and staggered cooking method, checking for tenderness toward the earlier end of each time range.
Can I double it for a crowd?
Yes, but plan for additional baking sheets or roast in batches. Crowding twice as many vegetables onto the same two pans will make browning harder. Multiple pans may also extend the cooking time.
