I didn't have any aluminum foil on hand so I put in on the lowest rack and cooked at 375 for 15 minutes *my oven is very old so it varies GREATLY from others I've used in the past. The tops are a little crispier than I'd like, but after I read some of the reviews about it being too soggy I decided to roll my meatballs in the sauce first and place 4 biscuits on bottom and 4 on top. Luckily because of this, my biscuits werent gummy or soggy! They were out of my regular beef meatballs so I decided to use turkey. (It would've been better with beef)
