Why We Love These Roasted Root Vegetables with Herbs

We have roasted vegetables almost once a week (if not more) and during the winter I’ll usually use a combination of root vegetables. Making them is second nature to me: Peel, cut according to density, toss with oil, salt, and pepper and roast.

When the root veggies come out of the oven, often they’ll just go onto the plate unadorned, their caramel-burnished exteriors, more than appealing enough. Though I have been known to drizzle on balsamic vinegar or toss the mixed vegetables with some defrosted pesto from last summer.

Today, I added fresh herbs and lemon zest which makes a nice contribution to the flavors of the vegetables.

Ingredients For Roasted Veggies with Herbs

  • Potatoes: We prefer thin-skinned potatoes such as red potatoes or yukon gold potatoes
  • Carrots: Peeled and cut
  • Celeriac: feel free to swap in another root veggie or kohlrabi. Check out more substitution ideas
  • Brussels sprouts: If they are large cut them in half
  • Extra virgin olive oil: for roasting. Sub in another cooking oil or ghee if desired
  • Coarse kosher salt and freshly ground pepper: to season
  • Herbs: You can choose a blend depending on your preference. We used a blend of chives, dill, tarragon and chervil for this batch
  • Zest from one lemon

How to Herb Roast Vegetables

So let’s talk about the technique. How does it work? How do you get all the veggies to cook at the same rate? How do you get them to brown on the outside and cook through perfectly? Let’s talk.

Step 1: Preheat the Oven and Cut the Veggies

I use a 400-degree oven to make root vegetables. Any hotter, and the sweeter veggies (like carrots) will over brown before the potatoes are cooked through. Any cooler and they will not brown and the potatoes will stick to the pan.

Wash and peel the veggies. Get rid of the dirt and bitter peels. I leave the skin on potatoes and sweet potatoes for added fiber.

Cut veggies mindfully: The trickiest part about mixing root vegetables and getting them to roast evenly is all in the size of the cuts. So you have to plan accordingly and cut some smaller and some larger to compensate for the different densities. Generally the harder the vegetable the longer it takes to cook through. So carrots, turnips, sweet potatoes and beets are very hard and they take the longest to soften. These you can cut slightly smaller. Celeriac, parsnips and potatoes are slightly softer and can be cut a little larger. To give you a sense of what I mean, today, I cut my potatoes into 1 1/2 inch chunks and my celeriac into 1-inch chunks.

Step 2: Mix Vegetables With Oil and Seasoning

Toss the cut vegetables with oil salt and pepper in a big bowl to coat them evenly. You have to be careful about adding herbs and garlic because they tend to burn before the vegetables are tender. Spices like smoked paprika and turmeric are okay. I save the bowl and use it again at the end to add in the flavorings (see tip #8.)

Step 3: Roast The Veggies

Don’t overcrowd: You want to allow air flow around the vegetables so that they brown. Moisture prevents caramelization. Crowded vegetables insulate each-other from the hot heat of the oven.  They end up steaming and will not brown.

If you have too many veggies to fit on a pan, just use two. Arrange your racks evenly in the oven to allow plenty of air flow, and plan to rotate your pans halfway. I’ll often use convection if I am doing two pans.

Stir only once or twice. If you try to stir the veggies too soon, they will stick to the pan. This is particularly the case with potatoes. So let them develop a nice brown bottom before turning them with a spatula.

Step 4: Finish with Herbs

How do you know when they are done? I usually try to chop a couple in half with the side of a thin spatula or test with a fork to make sure they are tender. If they seem tender, then I’ll eat one to make sure. Very scientific!

Once they come out of the oven, add on the fresh herbs and lemon zest.

Keep leftovers in a resealable storage container in the refrigerator up to three days.

How to reheat

Reheat the leftover roasted vegetables in an air fryer for 5 minutes. Heat in the microwave for 2 minutes. You can also reheat in the oven. Keep covered with foil to keep them from drying out. Heat until steaming hot.

What goes with herbed roasted vegetables?

This side dish can be paired with roasted poultry and pork as long as it is also roasted at 400 degrees. Try these roasted veggies with our healthy Baked Chicken Tenders. They’re also great with vegetarian main courses such as our Portobello Mushroom Sandwiches or Butternut Squash Macaroni and Cheese. More options include Seared Salmon or Crab Cakes.

Variations To Try

  • Instead of chopped herbs and lemon zest, add on a drizzle of high quality balsamic vinegar
  • Toss them with pesto once they come out of the oven
  • Add spices to the vegetables to roast with them

Alternative Veggies To Try

  • Instead of brussels sprouts you can use broccoli or cauliflower or chunks of green or red cabbage. Cut into florets
  • Instead of carrots use parsnips, beets or turnips. Cut into 3/4-inch chunks
  • Instead of potatoes try sweet potatoes cut into 1 inch chunks.
  • Avoid soft or watery veggies in this recipe or cut them into larger pieces. Examples are zucchini, red pepper or mushrooms.
