It’s easy to rely on oil to bring flavor and texture, but in fact there are lots of other ways to make food taste good. If you want to prepare crispy vegetables with little or no fat for example, you can use a hot air fryer, a pan with non-stick coating, or choose to fry the vegetables with a little water instead of fat/oil.
One great tip for anyone learning how to cook without oil is to replace the flavor it brings with natural flavor-enhancers. Herbs such as rosemary and thyme, as well as spices, such as chili flakes, pepper and garlic, are a great way to make tasty oven vegetables when you’re learning how to roast vegetables without oil. These work well with whichever veggies you have already.
Another important tool when it comes to making delicious oil free roasted vegetables is seasoning. The exact mix you use will depend on personal taste but a simple mix of salt, pepper and rosemary, or something fiery with curry, coriander, chili or Cajun spice will boost the flavor of your veggies without adding calories.
