These roasted root vegetables are hearty, flavorful, and easy to make. Roasted with olive oil and fresh herbs, they turn tender and caramelized for a comforting side dish that’s perfect for fall and winter meals.

There are some side dishes I end up making over and over again, usually without really planning to. They start out as something I make for a holiday or a special meal, and then somehow they become part of the regular dinner rotation. Roasted vegetables are one of those things for me. Once you realize how much flavor you can get out of them with very little effort, it’s hard not to keep coming back to them.

Root vegetables, in particular, are great for this. Over the years, I’ve roasted just about every root vegetable on its own. These honey roasted carrots and parsnips, maple roasted sweet potatoes, or these sweet potatoes tossed with Brussels sprouts and roasted until crisp. And not to mention, of course, baby potatoes, roasted until tender and tossed with spicy harissa, or asparagus.

This roasted root vegetables recipe is the version I reach for when I need a stunning, but simple and hearty side. The combination of carrots, parsnips, beets, sweet potatoes, and red onion makes for a beautiful jewel-toned mix that is super flexible, and works just as well for everyday dinners as it does for a holiday meal.

If you’re not sure about the beets, I get it. While beets haven’t always been my favorite vegetable, trust me when I say that there is a world of difference between those jarred marinated beets and fresh roasted beets. I promise these beets are SO delicious.

Depending on the season, I’ll sometimes swap in turnips, rutabagas, or golden beets, especially when I come home from the farmers market with more root vegetables than I planned on buying.

They all bring their own earthy flavor, but they roast in a similar way, so no need to separate them, just let them all share the same pan.

Why You’ll Love This Recipe

It’s the kind of side dish you don’t have to think about. Toss everything together, put it in the oven, and let it do its thing.

Roasting really brings these humble vegetables to life. Carrots, parsnips, beets, and sweet potatoes all get sweeter and more flavorful in a hot oven, with crisp edges and tender centers.

It fits into lots of different meals. These roasted root vegetables work just as well with a simple weeknight dinner as they do alongside a more special or holiday-style meal.

It’s easy to adapt. You can adjust the vegetables, change up the herbs, or scale it up or down without worrying too much about exact measurements.

It scales easily. This recipe doubles or triples well, which makes it a good option when you’re cooking for a crowd or adding it to a holiday menu.

Ingredient Notes

Carrots

Carrots add natural sweetness and hold their shape well when roasted. I like to cut them into larger, even pieces so they caramelize without drying out.

Parsnips

Parsnips become wonderfully sweet and slightly nutty in the oven. Make sure to peel them and cut them into pieces similar in size to the carrots so everything roasts evenly.

Beets

Beets add a deeper, earthy sweetness and a lot of color. I like to peel them before roasting so they cook up tender without any tough skins. Just keep in mind they’ll tint the other vegetables slightly, which doesn’t affect the flavor but does change the look.

Sweet Potato

Sweet potatoes bring a soft sweetness that ties all the other vegetables together. You can peel them or leave the skin on, depending on your preference. I usually do peel them. Either way, cutting them into even chunks helps them roast at the same rate as the rest.

Red Onion

Red onion softens and caramelizes as it roasts, adding a mild sweetness and a bit of contrast. Larger pieces work best here so they don’t burn before the vegetables are done.

Olive Oil

A good drizzle of olive oil helps everything roast evenly and develop that golden color. You want enough to coat the vegetables, but not so much that they feel greasy.

Fresh Rosemary & Thyme

Rosemary and thyme work especially well with root vegetables. Adding them toward the end of roasting keeps their flavor fresh and prevents them from becoming bitter.

Salt & Pepper

Simple seasoning is all you need here. A generous pinch of kosher salt helps bring out the natural flavors of the vegetables, and freshly ground black pepper adds just a bit of warmth.

Step-by-Step Instructions

1. Place an oven rack on the top 1/3 shelf and preheat the oven to 425 degrees F. Optional: line a baking sheet with parchment paper or aluminum foil for easy cleanup.

1. Add the carrots, parsnips, beets, sweet potato, and red onion to a large mixing bowl and toss with the olive oil until everything is evenly coated.

1. Spread the vegetables out in a single layer on the prepared pan and season generously with salt and pepper.

1. Roast for 20 minutes, stirring once halfway through, until the vegetables are tender and beginning to caramelize.

1. Take the pan out of the oven and toss the vegetables with the rosemary and thyme. Return the pan to the oven and roast for another 3–5 minutes, just until the herbs are fragrant.

Tips to Make The Perfect Roasted Root Vegetables

Cut the vegetables evenly. Keeping the pieces close in size helps everything roast at the same rate, so you don’t end up with some vegetables too soft while others need more time.

Choose vegetables with similar density. Carrots, parsnips, red beets, and sweet potatoes all roast at a similar pace, which is why they work so well together here. If you swap in other vegetables, keep that in mind so nothing overcooks.

Give them space on the pan. Spreading the vegetables out in a single layer allows them to roast and caramelize instead of steaming. If the pan looks crowded, it’s better to use two pans.

Roast first, add herbs later. Fresh rosemary and thyme can burn if they’re added too early. Stirring them in toward the end keeps their flavor bright and fragrant.

Season confidently. Root veggies need a good amount of salt to bring out their natural sweetness. If they taste flat at the end, a little extra seasoning usually fixes it.

Recipe Variations

Add a touch of sweetness. If you like your roasted vegetables on the sweeter side, drizzle a little maple syrup or honey over the vegetables before roasting. It works especially well with the carrots and parsnips.

Make it more savory. For a deeper, more savory flavor, add a few garlic cloves to the pan, or finish the vegetables with a sprinkle of grated Parmesan while they’re still warm.

Change up the herbs. Rosemary and thyme are classic with root vegetables, but sage or oregano work well too. Use what you have and what pairs best with the rest of your meal.

Add a bit of heat. A pinch of crushed red pepper flakes or a light sprinkle of chili powder adds warmth without overpowering the vegetables.

Add warm spices. A pinch of ground cumin adds warmth and depth and pairs especially well with beets and sweet potatoes.

Finish with a little acidity. A small splash of red wine vinegar tossed with the vegetables right after roasting helps balance their natural sweetness.

Storage Instructions

If you have leftovers, let the roasted root vegetables cool completely before storing them. Transfer them to an airtight container and keep them in the refrigerator, where they’ll hold up well for about 3 to 4 days.

When reheating, I find the oven works best. Spread the vegetables out on a sheet pan and warm them in a 375°F oven until heated through. This helps them keep some of their texture. The microwave is fine if you’re short on time, but the vegetables will be softer.

These also taste surprisingly good at room temperature, which makes leftovers easy to work into lunches the next day.
