How to roast vegetables for maximum flavor - 5 steps

How do you roast vegetables? It’s a simple question with a loaded answer! 

First, roasting vegetables can be done with and without oil. For the purposes of this post, we’ll cover the former, but if you want to learn how to roast sans oil, we’ve got you covered here. 

While roasting is an incredibly simple and efficient method to cook vegetables, there are ways to take your roasting skills up a notch! From tips for coating veggies to setting the correct oven temperature, we’re here to help make your roasted veggies better than ever —every time. 

What temperature should you roast vegetables in the oven? 

Roasting at the proper temperature is crucial when it comes to flavor and texture. Generally, most vegetables are roasted between 400F and 475 F. 

Swich tip: the smaller the vegetable pieces, the higher the oven temperature needs to be. This may sound counter-intuitive. But here’s why: smaller vegetables take less time to cook throughout. On the other hand, harder and bigger vegetables are better cooked at 350-400 to prevent the vegetables from burning.

Additionally, some vegetables with high water content (like tomatoes) should be slow roasted around 250F.

How to Roast Vegetables with Oil & Salt – 5 Steps 

1. Prepare vegetables 

No matter what vegetales you choose to roast, you’ll first want to wash, dry, and, if desired, peel them. Then, cut them in even pieces to ensure they cook at the same time. Generally, if you want bite-sized vegetables, you’ll cut them to about the size of your thumb. 

Note: While it’s ideal if vegetables are relatively evenly sized – it can be harder with certain vegetables like turnips and carrots that aren’t symmetrical. So just do your best! 

2. Toss them with fat or oil 

Oil absorbs the heat from the oven and raises the temperature of the food to help vegetables brown more evenly. Plus, it provides a protective barrier that helps prevent oil within the vegetable from evaporating. 

You’ll want the vegetables to be coated evenly without swimming in liquid. Vegetables such as cauliflower or broccoli need to be tossed especially well to make sure they’re evenly coated in the crevices. 

3. Season vegetables

Salt alone brings out natural flavor in vegetables, but you can also add pepper or other spices and herbs. See below for ideas based on the flavor you’re going for:

• Earthy: Rosemary and thyme

• Sour & sweet: Vinegar 

• Sweet: Sugar – this will add caramelization to the veggies, but keep in mind that sugar can burn easily at higher temperatures 

Vinaigrettes and dressings can also add instant flavor, but don’t add too much or they’ll steam the veggies rather than roast them. 

4. Place vegetables on a pan

This step often gets overlooked! But the way you place vegetables on a pan makes a big difference. 

First, we recommend lining a prepared baking pan with oil or parchment paper to avoid sticking and make cleaning up easier. Then, put vegetables in a single layer on the pan by lifting them out of the bowl with a spoon, clean hands, etc. Don’t pour the veggies directly from the bowl to the pan! This small step helps ensure excess water and oil is left behind.

Got a few pieces that are bigger than the rest? Scootch them to the perimeter of the pan. The edges are often the hottest, so this will help them cook more evenly.

5. Roast veggies in the center of the oven

It’s best to place the rack in the center of the oven for even heat (above and below). The hot air browns the top of the veggies while the pan itself absorbs the heat from the oven and caramelizes the bottom. Also, avoid crowding the vegetables to allow hot air to circulate.

Additional tips on roasting vegetables 

• Heavy duty pans are ideal since they allow for even heat distribution and circulation.

• Because salt draws moisture out of the food, season veggies just before roasting.

• Place vegetables hot side down when applicable.

• Ideally, roast different vegetables separately since they all cook at different times. You can combine them together afterwards! 

We hope this tutorial helped you! Roasted veggies pair wonderfully with almost any dish, so this is a skill that will come in handy often in the kitchen.
