Sweet Potato Casserole Boston Market Copycat

Sweet Potato Casserole Boston Market Copycat #Recipe #BostonMarket #sweetpotato @SlowRoasted

One of the most popular sides from Boston Market is waiting to be served on your table.  Our newest copycat recipe, Sweet Potato Casserole, is one for your recipe book!  Rich sweet potatoes covered in marshmallow and brown sugar streusel topping are a side dish to remember.

When Chad and I were first dating, most weekends, we would pick up a movie and head to Boston Market.  We would order our favorite meatloaf and sides for dinner and take it to go.  There is nothing quite like Boston Market meatloaf and sweet potato casserole, well except their corn bread.  That is pretty fabulous too.

On our way back to Chad's apartment we would stop and pick up a pint of ice cream.  Then we would sit down and enjoy our dinner while we watched The X-Files.  Do you remember that show?  Oh we watched it every week.  That was a great horror series!

These days it's more like Walking Dead.  That is our favorite horror series now.  But, in true form we sit down every week and enjoy that show.  Is it just me or do you enjoy staying at home?  We like going out every now and then but truth be told we are homebodies.  Being at home just fits.  Whether we are having game night, throwing parties or just cuddling up to a great movie, being at home is a good fit.

Growing up my parents never went out without us.  I could probably count on one hand the number of times we had a babysitter.  Perhaps watching my parents for the 42 years they were married, a few things rubbed off on me.

Whether its for Thanksgiving or a movie night this copycat Boston Market Sweet Potato Casserole is going to blow your mind.  Rich mashed sweet potatoes with butter, cream, brown sugar and spices are topped with marshmallow and a scrumptious crisp brown sugar streusel. The ultimate side for any meal. 

Dinner's Ready!

With love from our kitchen table to yours!  XO

  1. Can I use anything besides heavy cream in the sweet potato casseroles?

    1. You can substitute with half and half, milk, almond milk, soy milk... The flavor of each will change the casserole, but it will still be fabulous!

  2. Donna, this brings back memories of my childhood! This is just like the old fashioned sweet potato casserole my mom made for Thanksgiving every year. Sometimes old "is" better! Thanks for the memories!!

  3. Donna, this brings back memories of my childhood. This is almost exactly the sweet potato casserole that my mom would make every Thanksgiving. She didn't use rolled oats in the topping. Sometimes "old" is better! Thanks for bringing back the memories!!

  5. Donna, my husband loves Sweet Potato Casserole and, fortuntely, I found them on sale for .39/pound. Since I am going to roast and freeze them for later use, can you tell me how many cups equal 3½ - 4 pounds? Thank you.

    1. Hi LaWanda. According to this site - there are approximately 2 cups mashed in one pound. Hope that helps.

  6. I am so sorry. I am new to the sight and was not aware of that information. Thank you for pointing it out.

    1. Oh no problem at all Lawanda! I actually had no idea, so I looked it up. The information I found was from a separate site, that I why I linked you too it. Feel free to ask any questions, any time!


  7. Hi Donna! Could I use yams instead??? HUBBY bought them thinking they
    were sweet potatoes....these yams have dark skin and are orange inside.what do you think?

  8. Hi Donna! Could I use yams instead??? HUBBY bought them thinking they

    1. Yams would be fabulous! Happy Thanksgiving and let us know how it goes.

  9. This looks so good! I feel like I make the same things year after so maybe I should try this one!

  10. Totally different from mine. Pinning it and hope to try it!

  11. I have canned sweet potatoes that I need to use, have you tried this?
    Do you think it would make a big difference in taste?

  12. Do you think this would freeze well? We're going to be out of town visiting families for a few days and I'd rather make it at home to take rather than make it at their house! lol

  13. Do you remove the skin at any point?

    1. Yes, the recipe actually calls for peeled and cut sweet potatoes. Enjoy and let us know how it goes.

  14. I'm debating whether to try this recipe or just buy the Boston Market version for Friendsgiving! I've tried making sweet potato casserole before but the results weren't that great. This recipe looks easy enough! I might try it. :)

  15. Made this today ahead of time to have ready to put in the oven tomorrow for Thanksgiving. Had a couple test bites and omg I love this!!!! It's not too sweet like my sister makes and the vanilla really makes a difference. Thank you for sharing this wonderful recipe.Oh,and I used half milk and half and half and tastes yummy.

  16. Hello! This looks soooo yummy :) do you use small or large marshmallows?

    1. Mini marshmallows would work best. Enjoy and let us know how it goes.

  17. I'm not a fan of sweet potato casserole, or at least, I didn't think I was until trying this recipe. I made this for Thanksgiving this year, very delicious. Thank you for sharing!!
