5 Ways to Reheat Roasted Vegetables

Roasted vegetables are one of my favorite ways to get in my nutrients. They’re easy to cook and, have a lovely taste, and are a great way to use up any unused food!

Chances are, you’ll have some leftovers after you’ve eaten your meal. These vegetables taste so good right out of the oven- can they taste just as good reheated?

Yes! The reheating process is pretty simple and you can easily reheat roasted vegetables in a variety of methods. Below I outline 5 methods of reheating roasted vegetables- microwave, air fryer, oven, toaster oven, and stove top- and the best practice for freezing and storing.

What’s the best way to roast vegetables?

The way I roast my veggies is my tried-and-true way. The times may differ depending on the vegetable and size, but the method is the same.

First, I preheat my oven to 400 degrees F. 400 seems to be the best temperature when I do my cooking!

Next, I chop/slice my fresh veggies of choice, making sure they’re cut into smaller pieces for more even cooking.

I put the vegetables into a large bowl and drizzle with a little oil. I usually use olive oil, but any neutral oils will work. Then I sprinkle with salt and pepper and other seasonings depending on the dish and their own unique flavor:

  • Garlic powder
  • Onion powder
  • Chili powder
  • Cumin
  • Italian seasoning

Next, I empty the bowl onto a sheet pan, spreading the vegetables into a single layer. Some people use aluminum foil on the sheet pan, but I never do.

Then I place in the hot oven and cook for 20-30 minutes, depending on the vegetable:

  • Broccoli, cauliflower, zucchini- 20 minutes
  • Potatoes, butternut squash- 25-ish minutes

So the temperature is always 400 degrees F for me. But the amount of time for cooking changes. When in doubt, start with 20 minutes and poke with a fork to see if it’s done!

How do you store leftover roasted vegetables?

Once your leftover vegetables have cooled to room temperature, put them in an airtight container and keep in the fridge. They’ll usually last 3-5 days with proper storage.

How do you reheat roasted vegetables in the microwave?

I’ll be honest- the microwave is not the best method. It’s a quick and easy way to reheat food, but you end up with soft and mushy vegetables.

If you’re in a hurry, you can open your container of roasted vegetables and microwave in 30-second increments until they’re hot. You might have a slightly soggy outcome, but honestly it’s not the end of the world for me.

How do you reheat roasted vegetables in the oven?

The oven can help your vegetables crisp back up again. It takes a little time, but has good results!

Preheat the oven to 400 degrees, then place your vegetables on a baking tray and bake in the preheated oven for about 5 minutes until the vegetables are heated through.

This method may take the longest, because you have to wait for your oven to heat up.

How do you reheat roasted vegetables in an air fryer?

I LOVE my air fryer when the temperature gets too hot for the oven. You can actually roast vegetables fully in your air fryer!

Just place your vegetables in the air fryer and cook at 400 degrees F for 3-4 minutes. You don’t have to preheat the air fryer, and the cooking time is low enough that you may not need to shake the basket for even cooking.

How do you reheat roasted vegetables in a toaster oven?

I’ve grown to love my toaster oven for reheating pancakes, waffles, and other things. You can also use it for roasted vegetables!

Honestly, it depends on your model. I usually keep mine on the Toast setting and it works pretty well. It cooks for about a minute.

How do you reheat roasted vegetables on the stovetop?

This method doesn’t give the roasted veggies a nice crispy texture like the others, but it’s a good way to reheat if you don’t have a microwave.

In a large pan, heat the vegetables on medium heat for 5-6 minutes. You can add a little olive oil to help them crisp a little.

Is it safe to reheat vegetables?

I’ve personally had no problems with it.

The cooking process is relatively quick, so the veggies don’t sit at a low temperature for long periods of time and possibly collect bacteria.

As long as you refrigerate the vegetables soon after they hit room temperature, you lower that risk of anything harmful getting into your food.

How can you tell if the vegetables have gone bad?

The easiest way to see if you have rotten veggies is to look for visible signs:

  • White and/or fuzzy mold
  • Slimy texture

You can always do the smell test, too. If they smell kind of off, then just throw them out.

I typically keep roasted vegetables in the fridge for 4-5 days. If we haven’t eaten them by then, I dispose of them.

A good rule of thumb: If you have any doubt, throw it out!

What’s the best temp to reheat?

In my experience, 400 degrees is the perfect temperature. It’s the same temp I use to roast them for the first time, but obviously I don’t reheat them as long.

Can you roast vegetables the day before and reheat them the next day?

Absolutely! This will save you so much time, and I highly recommend this for meal prep sessions. I’ll make up a ton of vegetables and eat them a couple of days later.

With about an hour of work, you can easily have a few days worth of meals which saves both time AND money in the long run.

Can you freeze roasted vegetables?

You can, but keep in mind they might be a little softer after thawing!

Start by placing some parchment paper on a baking sheet and placing the vegetables in a single layer. This will make sure the veggies don’t freeze together. Place this in the freezer overnight, then transfer to a freezer bag. For best results, use them within 6 months. Not for safety reasons, but so you don’t risk the food getting freezer burn.
