put a bamboo cutting board on the top of the toaster oven. heat will not transfer past the cutting board. breville sells a $$ custom board with feet. We just use whatever Home Goods sells and it's been fine for 5 years. And that Breville oven (now with air fryer function) is our most used appliance.
