I'm writing this review on behalf of the GreenPan Kitchen Team and I truly cannot recommend a product more than the GreenPan Ovenware. NOTHING sticks to it! And you don't need any oil or butter or even parchment paper. It's SO easy to clean too and super lightweight. I made sticky caramelized brussels sprouts and they slid right off. Truly an amazing product and definitely the best ovenware on the market. Couldn't recommend more!
