These oil free rainbow roasted vegetables are so delicious, healthy, low in fat and easy to make. It's one of my favorite side dish recipes!
To roast vegetables without oil is possible and they taste amazing. I used balsamic vinegar, but soy sauce, tamari and lemon or lime juice also work. If you're on a diet or just trying to avoid oils, these oil free rainbow roasted vegetables are for you.
I try to eat as many different fruits and veggies as I can, I adore them and they nourish my body. I love these colorful rainbow veggies, they're full of antioxidants and nutrients, but there's no need to use so many vegetables, it's totally up to you.
When I tried this recipe for the first time, I couldn't believe it was oil-free, the veggies were so juicy and I only added the balsamic vinegar and dried thyme, but please feel free to add your favorite herbs and spices.
This recipe is ridiculously easy to make, you just have to place the chopped vegetables onto a baking sheet, add dried thyme and balsamic vinegar to taste and bake for about 25 minutes or until they're cooked. Besides, it's the perfect side dish! I love to eat these veggies with brown rice and some tamari or soy sauce, but they're also delicious with potatoes, pasta or quinoa.

Autumn says
I'm a lie to confused with the balsamic vinegar. I thought AW, said it's on the No list as msg is actually in this and not to use any vinegar but once in awhile Braggs ACV. ?? Thank you in advance as I would appreciate hearing more.
Iosune says
Hi Autumn! I think vinegar is a healthy food if you use it in moderation 🙂
Elizabeth says
Great recipe thanks for the suggestion. I make roasted veggies a lot but never tried using balsamic vinegar before. Great taste compliment! Also for whoever asked above - these DO freeze wonderfully. I take them from freezer and pop them in hot oven for 5 - 10 minutes when ready to eat.
Iosune says
Hi Elizabeth! Thanks a lot for your comment and your kind words. Have a beautiful day!
Virginia says
Es posible en español? Gracias.

Dev says
Wow! these veggies look simply great. I usually roast veggies at least once in a week and I use only one tsp of olive oil most of the time. But now I think I can totally omit it.
Iosune says
Hi Dev! Of course you can 🙂 Hope you enjoy this recipe!
Deb says
What a great idea! I would love to stop using oil. Thanks so much! I will definitely be giving this a try 😀
Iosune says
Thanks a lot Deb 🙂 Hope you like it!
Anwar says
I was skeptical but it is absolutely delicious! Properly roasted without oil as you said (I'm on a diet). If your vegan cheese is as great as this I will be over the moon 🙂 thanks, just signed up too
Iosune says
Hi Anwar! Thanks a lot 🙂 I'm so glad you enjoy this recipe!

Made this today and it was great!

Hi Stephanie! I'm so glad you liked it 🙂
Barbara Salem says
Thank you for sharing and for the great photos. I bet adding a few garlic gloves to the roasting tray and using rosemary might be a good alternative.
Iosune says
Hi Barbara! Sounds great, I love garlic and rosemary 🙂
Muskan says
Hi. Can a batch be prepared and refrigerated to be used next day?
Also, can I replace vinegar with lemon juice?
Iosune says
Hi Muskan! You can make it and store it in the fridge the next day 🙂 Lemon juice is also a great choice. Have a nice day!
Grant Jennings says
Looks like a fantastic recipe. Will try today and make ahead for a week (time saver!!!)
You call the recipe gluten free, which it sure is, however you mention seasoning with soya sauce above, which is RIDDLED with gluten.
... how come things are never riddled with good things? Can your veggies be riddled with love?
I'll be adding some MECHANICALLY EXTRACTED oil to this recipe, because I need the calories. Oil for the win.
Iosune says
Hi Grant! I used gluten-free soy sauce (tamari) 🙂
Lauren says
You told someone if they wanted to prepare it ahead of time, they could add an oil free sauce after... Any suggestions?
Iosune says
Hi Lauren! Ketchup, bbq sauce, more tamari or soy sauce, any sauce you like! I loooove this oil-free tahini dressing: http://simpleveganblog.com/simple-salad-with-oil-free-tahini-dressing/ It's so delicious!
Charlotte q says
Hi! Just wondering if the veggies would stick to the baking sheet because there's no oil? I really want to try oil-free roasting but have a hard time getting veggies not to stick even with oil!
Iosune says
Hi Charlotte! The veggies don't stick to my baking sheet, but you can use some parchtment paper or something like that if you want 🙂
Heather @ Simple Fresh Natural says
This is such a pretty dish!! And so easy. Love it when that happens! I love roasted veggies, so I am going to have to give this recipe a try asap!!
Iosune says

Shonda says
Could I add zucchini and squash?
Iosune says
Hi Shona! You can add any veggie you want 🙂
Rina says
Hi could you tell me how much balsamic vinegar to use? I tried the recipe with 1 tbsp vinegar and the end result was very dry.
Iosune says
Hi Rina! I don’t know exactly how much I add, but probably about 3 tbsp 🙂
Denise says
That's alot for just one person in the household can this be frozen, would it taste the same?
Iosune says
Hi Denise! You could use half the ingredients or even less if you want. I've never frozen it, so I don't know. Have a nice day!
