    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.

      Greetings! I made this recipe today adding asparagus and sweet potatoes. It turned out great and we had it over brown rice. I misted with water to keep from drying out. Next time I'll leave out the sweet potatoes - too dry. Thanks!

      I haven't made this recipe, although it looks delicious. I respect the right of vegans to avoid meat, but I found the comments made to Antoinette offensive and I won't come back to this website. For general info, some of us chose to eat meat, and still avoid fats or choose healthier options in other areas of cooking. Please respect our choices as we respect yours. Frankly, Iosune, if you had not thanked the people who made unkind comments, I would have returned to your site. Because you thanked them for their negative comments I won't be back.

      This answer might have turned up in the comments already, but did you sprinkle the balsamic vinegar over the baking sheet full of veggies, or did you toss the veggies in the vinegar before you spread them on the sheet? And would it even matter? :))

      Yum, thanks! I was planning on making a giant pasta salad to take to a picnic and these roasted veggies were fantastic in it and brought it to a whole new level, hot or cold! I tossed in some chopped tomatoes, canned black olives and water packed artichoke hearts, reserved some liquid from both, and blended it with an avocado, silken tofu, lemon and more balsamic, and some Mediterranean herbs, for a creamy no oil dressing... awesome!

      Hello! I was reading your post about starting a food website and saw that you mentioned using the Foodie theme. Are you still using that theme? I bought Foodie thinking it could look like your beautiful website but I'm wondering if you since switched to a more customized theme (as I can't achieve that look)? If so, you may consider updating that info so that clueless people like me don't purchase Foodie thinking it will look as good as yours 🙂

      I was searching for a side dish to make tonight, this looks amazing. Thank you. However, in reading the reviews I almost do not want to follow this site (not due to the author), because people are just MEAN. There was no warning or statement that says if you are not vegan you are not allowed on this site. People were leaving nice reviews and were attacked for their choices. Not cool. Everyone is on a journey, instead of berating, why not encourage them along the way! How awesome that people are making and eating this great and healthy recipe! Why chase them away from possibly finding more great and healthy recipes?? Iosune this is NOT directed at you, but the people who responded.

        I’m not trying to be mean with this comment to Loxner but this is how I feel about the comment. If you eat meat and dairy you haven’t made the connection between the cruelty and slaughter you’re financing everyday by what you’re choosing to put on your plate . To vegans and vegetarians this is highly offensive. I’m tired of explaining why I’m vegan. How difficult is it to understand? Cruelty and slaughter of animals is “not cool”. It’s indefensible!! Visit a factory farm or abattoir. Or just peer through the tiny holes on an animal transport truck. Look into the eyes of any individual animal. You’ll feel their terror and helplessness.They have miserable lives full of pain and suffering and horrific deaths. It will help you understand why vegans feel and speak the way we do. It certainly will open your eyes. Don’t get me started on the health benefits of being vegan.

      Thank you for such a delicious recipe! I was a skeptic, but no more! For years I couldn't imagine cooking without oil, but you have opened a whole new world for me. I followed the recipe as is with one addition: Coconut Aminos with Garlic! Yum!
