Copycat Boston Market Sweet Potato Casserole

I cannot believe it is already the week of Thanksgiving!!

Being such a big foodie Thanksgiving is naturally one of my favorite holidays! This year I am heading to my family’s house on Cape Cod and I am looking forward to spending a few days relaxing, cooking, and of course EATING! While I will splurge during the Thanksgiving meal I do plan to get my workouts in daily, drink my superfood shake each morning and make sure I drink plenty of water.

My Dad loves the sweet potato recipe from Boston Market so over the past few years I have been making him this copycat recipe. It has become a HUGE hit at the table and I get asked for the recipe repeatedly so here it is!




Since this recipe is so NOT 21 Day Fix approved here are some tips to set you up for success on Thanksgiving day as well as a video from 21 Day Fix creator Autumn Calabrese on “How to Survive Thanksgiving Dinner”.

My tip for you? Control what you can control but also enjoy the holiday time and all the yummy foods and drinks that come with it! The worst thing you can do is totally deprive yourself – if you do that you are setting yourself up for a much larger splurge in the future that may not be as easy to get back on track from after.
