How to Oil Free Roasted Vegetables

It took me a few tries to figure out how to roast your vegetables (or even grill vegetables) without using any oil. Once you start to use less oil though, you will notice that you do not miss it, though! 

I talked about this oil free method recently in our Roasted Cauliflower with Chipotle Coconut Cream recipe – if you don’t use oil you need to use another ‘wet’ ingredient! I have found that vegetable broth works very well! And another bonus of using vegetable broth is you can cut down or omit adding salt.  

In this recipe, though, I tried a different method. I tossed the vegetables with some white wine vinegar and a splash of amino acids.   The result (drumroll please) it worked! You get flavor depth from the white wine vinegar and amino acids and it is OIL FREE!

If you are worried about your vegetables sticking to the pan, use parchment paper or a non stick silicone mat. I use these silpat mats and then I spray them lightly with cooking spray (I know that is oil, but use lightly).

Dairy Free Lemon Cream Sauce

 So why a lemon cream? It’s winter. And it’s cold and often gray skies. I felt like I needed something warm and cheery! Plus, Brussel sprouts have been on sale the last few weeks at the grocery store and lemon and Brussel sprouts pair really well together. (or at least they do to me!)  

Do you like tart? I will say I am a mild tart fan. My little girl will just eat lemon slices by themselves! WOW. A little too much tart for my taste. But everyone is different.  If you love tart like my daughter, feel free to omit the maple syrup. If you really dislike tart, add another teaspoon of maple syrup. That is a the great thing about a sauce, you can always tweak it to make it ‘your own’.  

To keep this dairy free sauce, creamy, I used a lite coconut milk. It adds a level of flavor depth while making the sauce creamy! And because I used such a small amount, you will not get an overly coconut taste.
