Roasted Potatoes, Carrots and Onions is one of those simple side dishes I rely on when dinner needs something hearty without a lot of extra work. Potatoes, carrots, sweet onion, and garlic roast together with olive oil, thyme, parsley, salt, and pepper until the vegetables are tender and the edges turn deeply golden.
I like this combination because the vegetables cook in the same pan and each one brings something different. The potatoes become crisp around the edges, the carrots turn naturally sweet, and the onion softens and caramelizes between the other vegetables.
This is an easy side for roast chicken, pork chops, steak, meatloaf, or a holiday dinner. It also works well when I want a vegetable dish that feels more substantial than a simple salad.
Why You’ll Love These Roasted Vegetables
- Simple ingredients: The recipe uses basic vegetables, olive oil, garlic, and dried herbs.
- One-pan side dish: Everything roasts together on one sheet pan.
- Great texture: Covering the vegetables first helps them soften, then uncovering the pan lets the edges brown.
- Easy to pair: The mild garlic-and-herb seasoning works with chicken, beef, pork, or holiday mains.
- Good for meal prep: Leftovers reheat well for easy lunches and dinners.
Ingredient Notes
Potatoes: Leave the skins on if they are clean and in good condition. Cutting the potatoes into evenly sized pieces helps them roast at the same rate.
Carrots: Peel and cut them into bite-size pieces. Try to keep the pieces similar in thickness so you do not end up with some carrots soft and others still firm.
Sweet onion: Cutting the onion into larger wedges helps it hold its shape during the long roasting time.
Garlic: Minced garlic adds plenty of savory flavor. Toss it thoroughly with the olive oil so it is distributed rather than sitting in one spot on the pan.
Thyme and parsley: These dried herbs keep the seasoning simple and versatile. They add flavor without overpowering the vegetables.

How to Make Roasted Potatoes, Carrots and Onions
- Preheat the oven to 475°F.
- Peel the carrots and cut them into bite-size pieces.
- Cut the potatoes into bite-size pieces, leaving the skins on if desired.
- Cut the sweet onion into eighths and mince the garlic.
- Place the carrots, potatoes, and onion in a large bowl.
- Drizzle the olive oil over the vegetables. Add the garlic, thyme, parsley, salt, and pepper.
- Toss thoroughly until the vegetables are evenly coated with oil and seasoning.
- Arrange the vegetables in a single layer on a large sheet pan and cover the pan with foil.
- Roast for 45 minutes.
- Remove the foil and continue roasting for about 30 minutes, stirring every 10 minutes, until the vegetables are tender and golden brown.
Tips for Better Roasted Potatoes and Carrots
Cut everything evenly. Size matters more than perfect shape. Similar pieces cook more evenly and give you a better mix of tender centers and browned edges.
Use a large enough pan. The vegetables should sit mostly in one layer. If they are piled deeply on top of each other, they will steam more and brown less.
Do not skip the uncovered finish. The first part of the roasting time softens the vegetables under foil. Removing the foil is what allows moisture to escape and helps the edges develop color.
Stir during the final roasting time. Turning the vegetables exposes different surfaces to the hot pan and helps prevent the garlic or smaller pieces from getting too dark in one spot.
What to Serve with Roasted Potatoes, Carrots and Onions
I serve this side with roast chicken, baked chicken breasts, pork chops, pot roast, meatloaf, ham, or steak. Because the seasoning is simple, it also fits naturally on a Thanksgiving or Christmas dinner table.

Storage and Reheating
Store cooled leftovers in an airtight container in the refrigerator for up to 4 days. For the best texture, reheat them on a sheet pan in a hot oven or air fryer until heated through and lightly crisp again.
The microwave works when you are in a hurry, but the vegetables will be softer because they do not have a chance to re-crisp.
Frequently Asked Questions
Do I have to peel the potatoes?
No. You can leave the potato skins on as long as the potatoes are scrubbed well. The skins add texture and help the pieces hold together while roasting.
Why are my roasted vegetables not browning?
Overcrowding is one of the most common reasons. Give the vegetables enough space, remove the foil for the final part of cooking, and stir them periodically so more surfaces touch the hot pan.
Can I prepare the vegetables ahead?
You can peel and cut the carrots and onion ahead of time. Potatoes can discolor after cutting, so if you prep them early, keep them covered in cold water in the refrigerator and dry them very well before adding the oil and seasonings.
