Merry Xmas everyone

I would like to try this recipe for Turnip Puff I heard about it today.
Looked up the recipe and it says to bake about 35 min.
My question is how can I have this ready for dinner and the turkey too at
the same time, considering they both need to use the oven? How do you all
do it?
New to cooking a Xmas dinner for 10.
Thanks in advance. Will eagerly await your replies.
