Sure you just roast at 25* to 50* less power. I would use 250 to 275 deg. for beef ribs for 2 to 4 hrs. It will depend on the size and meatiness of the ribs. I love my convection oven. If you use the reg. power of 300 to 325, you would cut the time down by an hour. Might want to read the book with your stove for more suggestions.ross said:can you roast beef ribs in a convection oven? what temp? how long?
