I have hosted Thanksgiving dinner, yes we do dinner at 7pm, every year since I got married almost 20 years ago. I wanted to start traditions for my new family that could hopefully be passed down.  My mom passed down the cornbread dressing and Ritz pie (I will get to that one later-but it is AWESOME!) and I started the tradition of Crab Cakes and Champagne as an appetizer to ring in the holiday season.  Everyone looks forward to it each year and it has become my contribution to the family traditions.
I think that traditions are so important in families.  They create memories and feelings of comfort and security.  Don’t be afraid to host Thanksgiving and actually cook Thanksgiving.  It’s not that hard-it’s just dinner.  People are there to be together and celebrate the season.  Seriously, just pour really good wine or cocktails and they will never notice the food.
Start small and come up with a menu that you can assign dishes to people to bring.  Decide on which dish you want to make and make it!  I promise it will be fabulous and you can do it!  And, the next year you can add another dish to your repertoire.
The trick to hosting Thanksgiving or any dinner party is to be organized.  I am not saying that you need to start three weeks in advance-that is just crazy and exhausting!  Once you finalize your plans of who, when and where, sit down and create a menu, a time line of the day of the event and a to-do list.  Don’t get too ambitious-just make the turkey and two side dishes. Have guests bring desserts. If someone wants or has to have a particular dish then have them bring it. You do not need 400 side dishes and desserts!
Creating a time line for the day is so important. If you are having dinner at 7pm you don’t want to chill the wine at 6:50pm.  Start with the time you want to eat and work your way back. And, keep your kitchen clean while you cook. Put dirty dishes in the dishwasher, wipe up the counter after each task, put trash in the trash can.  Stay clean and you will feel organized.
Here is a rough time line of my Thanksgiving Day/Week.
Monday-  Read through recipes and buy groceries and wine. Put frozen turkey in fridge to thaw-it takes a few days
Tuesday–  Buy flowers
