These roasted root vegetables are very easy to make and can be served with meat, fish, and poultry. They also make a great addition to salads and veggie and grain bowls.

Which Root Vegetables are Good for Roasting?

There are quite a few root vegetables that a good for roasting. Here are a few examples:

  • carrots
  • beets
  • fennel
  • turnip
  • parsnip
  • rutabaga
  • potatoes
  • sweet potatoes
  • yams
  • celeriac
  • onion
  • garlic

Do You Peel Root Vegetables Before Roasting Them?

In general, it depends on the type of vegetable, the method of roasting, and whether or not its skin is edible.

For this particular recipe, I only leave the skin on potatoes and peel all the other vegetables. Even though carrot and beet skin is edible, I don’t like the texture of it.

If you prefer to leave the skin on, make sure to thoroughly scrub it to remove all dirt and sand.

Can I Roast Root Vegetables in Advance?

Roasted root vegetables taste best just out of the oven. So, if you are preparing them for Thanksgiving dinner or any other occasion, I suggest popping them into the oven just before dinner.

The good thing about roasting vegetables is that you don’t have to constantly watch over them so you can do other things while the vegetables are roasting.

Having said that, even though they might not look the best, the leftover roasted root vegetables taste just fine.

So, if you are making them for a meal-prep at the start of the week, I think it’s totally fine to prepare them in advance and reheat for dinner or add them to salads and grain bowls to take to work for lunch.

How to Store and Re-Heat Roasted Root Vegetables

Roasted root vegetables can be stored in the fridge in a glass container with a tight lid for two to three days.

There are a few ways you can reheat roasted root vegetables:

  • in an oven: to reheat the vegetables in the oven, spread them over a baking sheet in a single layer and reheat at 375F until they are warm enough to eat;
  • in a skillet: to reheat the vegetables in a skillet, heat some olive oil in a wide skillet over medium heat. Add the vegetables and reheat them, stirring occasionally until they are warm enough to eat;
  • in a microwave: small portions can also be reheated in a microwave oven.

Tips for Preparing the Best Roasted Root Vegetables

Roasted root vegetables are quite easy to make. All you need to do is peel and slice the veggies, add some aromatics such as herbs, spices, onion, and garlic, toss the vegetables in olive oil, and season with salt and pepper. Then roast them in the oven until nice a golden.

Even though this recipe is very simple, there are still a few things that will help you to take your roasted root vegetables from good to great:

1. Pat Dry the Vegetables After Washing Them

If you wash the vegetables, make sure to pat them dry. Roasting the vegetables requires them to cook in dry heat, so any excess moisture will cause them to steam instead of roasting, which will result in soft limp vegetables.

2. Cut the Vegetables into Uniformly Sized Pieces

It’s important to cut the vegetables into uniform pieces so that they cook through at the same time. Beets are denser than the other vegetables, so slice them into smaller pieces than the rest.

3. Spread the Vegetables in a Single Layer on a Baking Sheet

Spread the vegetables in a single layer on a baking sheet so that they are heated evenly. Piling the vegetables on top of each other will cause them to steam instead of roast. If you are making a big batch, you can use two baking sheets to give the vegetables more space.

4. Add Aromatics

Nobody likes bland and boring vegetables. Spice up your veggies with herbs, spices, garlic, onion, and of course, olive oil. Don’t be afraid to experiment and create your own favorite flavor combination.

5. Don’t Over-Cook or Under-Cook the Vegetables

Check on the vegetables often at the end of cooking because over-cooked roasted vegetables can become dry very quickly. But you also don’t want to under-cook them because under-cooked vegetables don’t taste very good.

The vegetables are done when they start turning golden on the outside and are soft on the inside. You might need to practice a few times to get them out of the oven at the perfect moment.

How to Make Roasted Root Vegetables

Roasted vegetables are a perfect side dish that you can prepare in just a few easy steps:

Step 1.

Separate thyme leaves from stems. You would need about one tablespoon of thyme leaves. Keep the stems because you can add them to the vegetables, too, for more flavor.

Step 2.

Cut all the vegetables into uniform pieces. Cut the beets a bit smaller than the rest because they are denser and take longer to cook.

Place the cut potatoes, carrots, and sweet potatoes into a bowl. Add the thyme leaves and 1 3/4 tablespoon of olive oil, season with salt and pepper, and mix, making sure all vegetables are covered with oil.

Step 3.

I keep the beets separate from the other vegetables so that they don’t discolor. If you don’t mind getting the beet juice on other vegetables, you can just mix them all together in one bowl.

Otherwise, place the sliced beets into another bowl and add the rest of thyme leaves and 3/4 tablespoon of olive oil, season with salt and pepper. Mix to combine, making sure all beets are covered in olive oil.

Step 4.

Preheat the oven to 400F. Transfer the vegetables onto a baking sheet. Spread the vegetables over the baking sheet in one layer. Transfer the beets to one side of the baking sheet so that the beets don’t discolor other vegetables.

Add garlic, onion, and a few thyme sprigs, and the stems that are left from Step 1.

Step 5.

Place the baking sheet onto the oven and roast the vegetables until cooked through for about 40 to 45 minutes. Make sure to mix them at least once or twice during cooking.
