Like a casserole dish in design and purpose, this cooking utensil is made of 100% food-grade silicone and has a 14-cup capacity. Keeps food moist. Lock in more vitamins & minerals by steaming food without adding water or oil. Comes with a Multipurpose Tray to separate food (cook veggies on the bottom, protein up top) or use as a spill guard to prevent from overflowing. Fewer dishes to clean up: prep, mix and cook all in one!
