    Some food just looks beautiful, the colours sing and the dish is like a picture on the plate. This balsamic onion and beetroot bake is almost that dish. When you prepare it and get it all in the roasting tin it is a glorious sight, the deep purple vegetables are flecked with greeny blue thyme. Then you add a gloss of oil and a dark brown drizzle of balsamic vinegar and it looks like a piece of modern art. I think these pictures are some of my favourite food prep photos ever. When I took them I wanted to get them framed and put it on my kitchen wall (in fact I may still do that!!!).

    Then I cooked the dish! I was so disappointed, so disappointed that I almost didn't share the recipe with you. My glorious piece of food art had turned into what looked like lumps of charcoal. At first I thought I had burnt it, but the beetroot was soft and the onions were sweet and caramelised. It wasn't burnt it just wasn't pretty.

    So I am sharing more photos of before it went into the oven 🙂 this dish is beautiful before it is cooked and delicious when it is cooked.

    The sweet beetroot and onion are roasted with balsamic vinegar, oil and fresh thyme. I like to add a drizzle of maple syrup, but that really isn't necessary. This is a delicious dish without it, but I just love maple syrup glazed veg!

      I love roasting vegetables! It gives them a glorious taste. I love the addition of the maple syrup! It's always great to have something sweet to counteract the acidic taste of the balsamic. This looks scrumptious, and I can't wait to try this!
      I recently made a cooking and baking blog, too.

      This looks so delicious and there is so much it would go with. Some Jersey Royals would be delicious with this, but then it would be amazing in a cold pasta salad or stirred through cous cous. Oh the possibilities are endless 🙂

      A delicious recipe, I found your site through #TryABiteTuesday

        Stirred through couscous is a great idea, maybe with some feta crumbled over the top. Yum!

      That really is such a pretty before photo but the 'after' is good too and sounds delicious - I love that sweet/earthy flavour combination

        Thank you Nicole, I think it was mostly disappointment that the beautiful colours has disappeared. I wanted to eat the raw picture 😉 but the cooked one was definitely delicious.

      I absolutely adore purple vegies (most of us don't eat enough of them). The colours are gorgeous and I just bet it tasted wonderful 🙂
