How To Reheat Roasted Vegetables: Simple Tips And Tricks

In summary: There are two ways to reheat roasted vegetables: (1) reheating in the oven at 450 °F by spreading them on a baking sheet and baking with a little olive oil, and (2) heating in an air fryer at 400 °F by spreading the vegetables in the fryer basket and cooking for 2 to 3 minutes.

Roasted vegetables are best when freshly grilled or taken out of the oven. Unfortunately, no subsequent warm-up can give such a perfect result and lovely taste. 

You know what we mean. Tasty, crunchy, fragrant, and delicate fresh veggies, in some cases, can be more delicious than the meat itself.

Anyone who has tried at least once in their life to reheat roasted vegetables knows that it is not a thankful task. What was initially a perfectly crispy vegetable becomes watery, gooey, and not at all crunchy.

So when reheating, you have to do it in the air fryer or an oven and at a high temperature to dry as quickly as possible and make the roasted vegetables crispy.

Reheating Roasted Vegetables In The Oven

As we mentioned, aside from an air fryer, the only way to properly reheat roasted vegetables is in the oven.

Unfortunately, other methods will not work so well, especially the microwave. Though we know you were hoping for that quick and easy solution. The microwave will only soften the vegetables and really won’t be as tasty as you want.

Since the vegetables stood for one day, you know that it has lost its shape and has become soft and slightly gooey. The key to reheating is to quickly restore its texture, extract excess moisture, and try to make it crispy. Here are the steps to take.

Step 1: Preheat the Oven to 450 °F

High temperature is necessary to reheat roasted vegetables. You have to shock it in some way with the high temperature. If you heat it over medium heat, it will only soften further and, although it will be hot, it will not be tasty and crunchy. 

Therefore, set the oven to 450 degrees Fahrenheit and let it heat up thoroughly. Do not even accidentally start reheating until the oven is completely hot.

Step 2: Spread out the Vegetables on a Baking Sheet

For this occasion, you can use a baking rack on which you will put baking paper. That way, the vegetables will be heated on all sides, which is better.

The paper will, of course, prevent the food from falling through the bars and creating a mess. However, if you do not want to, you can also use a baking tray.

Place pieces of roasted veggies on a baking sheet by spreading them over the surface. Do not throw them on top of each other as they will remain soft and gooey. Arrange them so that they have enough space to warm up on all sides and become crispy.

Step 3: Sprinkle a Little Olive Oil and Bake

When you have arranged the vegetables, sprinkle it with a little olive oil, which will give it aroma and help with baking. Place the vegetables in a preheated oven and bake for five minutes. 

It should be enough time for the vegetables to warm up, regain the texture, and become fine and tasty. 

If you estimate that you need to leave an extra minute or two to make it perfect to your taste, then you can. Just be careful not to burn it. Reheated roasted vegetables should be close to freshly made ones.

Be aware that the temperature is quite high, and some vegetables might start to burn, especially the delicate ones like zucchini. 

Heating Roasted Vegetables In An Air Fryer

If you’ve invested money in an air fryer, we’ll just say it’s well spent, especially if you want to reheat crunchy vegetables. 

This is undoubtedly a better method than the classic or toaster oven because the hot air will further dry out the moist vegetables and make them firmer and crispier. 

So if you have an air fryer, choose it instead of an oven. In addition, we do not need to mention that this method is significantly faster.

Step 1: Preheat the Air Fryer to 400 °F

Even in the case of the air fryer method, we want a high temperature and a quick, crispy result. You only have to be careful not to overdo the cooking time so as not to burn the vegetables. 

Turn on the appliance to 400 degrees and let it heat thoroughly. During this time, arrange the leftover vegetables.

Step 2: Spread out the Vegetables in a Fryer Basket

We will immediately say that separating the heating into several cycles is better than overcrowding the basket. 

Just like in the case of a toaster oven, if you overlap the vegetables and stack them, everything will remain rubbery and soft. Therefore, arrange the pieces of vegetables in the air fryer basket so that there is some space between them. 

You can cover the bottom of the basket with parchment paper or aluminum foil to make everything neater.

Step 3: Cook for 2 to 3 Minutes

When the air fryer is well heated, insert the basket with vegetables and turn it on for 2 minutes. Take it outside and check the result. If necessary, return to additional heating for a minute or two. Be careful not to burn your vegetables.

When everything is well heated, serve immediately, as the roasted veggies will become softer and less tasty once they cool down. That’s why it’s best to leave reheating vegetables as the last step in the meal preparation and serve them while they’re piping hot.



Reheating leftover vegetables is undoubtedly a big challenge for any chef if he wants to have the perfect dish with a fine crispy texture. 

Microwave won’t help because it will make the food even softer, and less tasty. If you don’t have a fryer, the only solution is preheating in the oven at a high temperature. Follow our tips, and you will get the most out of leftover roasted vegetables. If you do everything as suggested, you’ll come to a conclusion reheating roasted vegetables is not that terrifying after all.
