Syn Free Roast Potatoes on Slimming World

This recipe for Syn Free Roast Potatoes is perfect whether you’re following the Slimming World plan or just trying to reduce the amount of saturated fat in your diet. I’ve been making roast potatoes using low calorie cooking spray now for more than three years, and I would never go back even if I weren’t trying to be healthy!

I’m not exaggerating when I say that cooking with low cal spray makes the best ever roast potatoes – Slimming World or no Slimming World! The reason for this is that it distributes the oil around the whole potato, making sure that the whole thing ends up crispy and delicious whilst keeping the inside of the potato as gorgeously fluffy as you could want.

How To Pimp Your Slimming World Friendly Roast Potatoes

Ok, so roast potatoes are pretty epic all on their own, and if you’re enjoying them with a classic roast dinner then they’re perfect how they are. But I’ve never been one to do things by halves though, so I wanted to share one way that you can make them even better! In my opinion, anything can be improved beyond perfection by the addition of cheese and bacon and if you’re anything like me then you’ll agree.

Once you’ve made your syn free roast potatoes, you simply need to fry up some bacon (fat removed to keep it syn free) and then layer the potatoes in a small personal baking dish with your Healthy Extra portion of cheese and the crispy bacon! Bake for a further 10 minutes or until the cheese is melted and has started to crisp up on top.

    These look like some deliciously crispy roast potatoes. This is how we do ours too, with fry light.

    I don't suppose there is anything better than a crispy roasted potato! I love that you par boil them fist, sometimes, if you don't they get too browned! Can't wait to try your method!

    We make roasted potatoes all the time but I have never thought to make them with a low calorie spray. Makes perfect sense and a healthier option at that. Thanks for sharing!
