About Boston Market

As everyone knows, Boston Market is not just in Boston. It’s a chain of fast-casual stores that specializes in rotisserie chicken and other meat dishes, along with a choice of sides. However, the founders, Arthur Cores and Steven Kolow, did reside in Boston.

Their concept was to provide food that was fresh and healthy but delivered quickly at prices closer to those of your typical fast food.

First Boston Market Locations

In 1985, the founders opened the first store which was called the Boston Chicken store. The store was a huge success, the Boston Globe wrote it up, and the line stretched well outside the door.

Following a couple of changes in ownership, by the end of 1992, there were 217 stores throughout the U.S., and in 1995 the name was changed to Boston Market to reflect the fact that the stores did not just sell chicken.

The chain went through more ownership changes, and as of the beginning of 2018, there were approximately 450 Boston Markets spread over twenty-eight states. Read more about the history of Boston Market.

Make Ahead Notes

If you want to make this ahead of time, I suggest you bake it fully and then reheat it on the 2nd day in the oven. The raw eggs in this dish make this undesirable to mix ahead one day and to bake the second day.

Ingredients

Sweet Potato Layer

  • 5 pounds sweet potatoes
  • 4 tablespoons butter
  • 2 eggs slightly beaten
  • 1 teaspoon salt
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon vanilla extract
  • 1/2 teaspoon ground nutmeg
  • 1/2 cup dark brown sugar
  • 1/4 cup heavy cream
  • Nonstick cooking spray

Cookie Crust Layer

  • 1/2 cup all-purpose flour
  • 1 cup dark brown sugar
  • 1/4 teaspoon salt
  • 1 cup quick-cooking oats
  • 1/2 teaspoon ground cinnamon
  • 1/4 pound butter
  • 2 cups miniature marshmallows

Instructions

Sweet Potato Layer

  • Preheat the oven to 350 degrees F.

  • Wrap sweet potatoes in foil, place them on a baking sheet and bake for about 1 hour. After 1 hour, test by piercing with a fork; if you can pierce them easily, they are done baking. If not, bake them a little longer and test again. Allow the sweet potatoes to cool until you can handle them, remove foil, and remove skins by simply pushing off the skins from the flesh of the potato.

  • Place the cooked potatoes into a large bowl. If using canned sweet potatoes, skip the baking. Just open the cans and drain off the syrup. Mash the sweet potatoes with the butter using a pastry blender or a potato masher until mostly smooth.

  • Add the eggs, salt, cinnamon, vanilla, and nutmeg and beat until you have a uniform mixture. Add the brown sugar and cream and mix well.

Oatmeal Cookie Crust

  • Combine the flour, brown sugar, salt, oats, and cinnamon in a medium bowl and stir together well. Stir in the 1/4 pound butter with a fork until you have a crumbly mixture.

Casserole

  • If you had turned off the oven, heat it again to 350 degrees F. Lightly coat a 9 x 13-inch baking pan with cooking spray.

  • Spread the sweet potatoes in the pan. Top with the marshmallows, then crumble the oatmeal crust on top of the marshmallows. Bake 30 to 45 minutes.

    Why is it called a cookie crust when it is put on top of the sweet potatoes

    Reply

    • Stephanie Manley

      Because it is essentially a cookie batter on top of the sweet potatoes.

    Could i use a fourth of cream cheese for the heavy cream in the sweet potato layer?

    Reply

    • Stephanie Manley

      I don’t think that would work because you need the liquid of the heavy cream. I haven’t tested any modifications, but if I was going for a reduction in calories why not swap it for half and half?

    I give this a 4.5 out of five. Delicious!! I used the canned sweet potatoes/yams so it came out a bit runny but did not affect the taste at all. Very easy to follow and a perfect replacement to the Boston Market side.

    Hi! I’ve made this many times and love it! But i started to have a sensitivity to eggs. Would it still work the same if I just omitted the eggs and still followed the rest of the recipe?

    Thanks for the recipes Stephanie! Do you think I’d be ok to freeze this dish after I make it? My brother gave me a box of sweet potatoes as a gag gift for my birthday, and my husband and I won’t be able to eat a whole box before it goes bad. I hate seeing food go bad ☹️

    I need to make this the night before and bake it before dinner… Can I refrigerate the crumb topping after I’ve mixed all the ingredients? Thanks for any advice.

    Reply

    • Stephanie

      I am not certain of the results if you do this. Flour tends to change over a long refrigeratoration.

      Reply

    • Stephanie

      Sure, this should work. You might just want to bake it, and reheat it.

    I made this for Thanksgiving. It was amazing! Everyone loved it. Even non sweet potato eaters loved it. It tastes better than Boston Markets.

    I’ve made this recipe quite a few times, and it’s always a big hit with everyone! Thanks for sharing it with us! I do have a question though, since I lost my recipe. When I looked up this one again, your recipe directions and ingredients say 4 Tbsp (1/2 stick) of butter with the potato mixture and 1 whole stick for the cookie topping, but in your comments and responses, you say 1/2 stick in the potato mixture and 1/2 stick in the crumble mixture, so I’m kind of confused of which way I should follow. I believe when I’ve made it in the past, I used 1/2 stick in the potatoes and 1 whole stick in the cookie topping, but now I’m questioning that. Can you please let us know which way is the right one and possibly update the right one? I’m going with the actual directions since that’s the way I think I made it in the past, but the other comments may confuse people. Thanks again for giving us this amazing recipe! Happy Thanksgiving!

      I noticed that too, I made it last week for an early thanksgiving gathering following the recipe, and it turned out great. I am making it again today using the 1 stick of butter in both the potatoes and the topping. I can’t see it hurting any.

      Reply

    • Stephanie

      Please use the directions as written. It’s 4 tablespoons for the potatoes and a stick for the oatmeal cookie crumb topping.

    Hey I used half a stick of butter and then used cream cheese for the rest. No particular measurements, just by taste and texture. Kept adding. I added pumpkin spice too, just a little. I also used a little bit of granulated sugar, brown sugar was a tad bland for me. ✋Great recipe, I’m here for the holidays.

    Stephanie, this recipe is absolutely fabulous!! Every year I try to make sweet potato casserole and I’m never happy. My husband’s favorite is Boston Market’s SP casserole. So, I thought, I’ll just buy them. Cost was $80. No thanks. I made 1 1/2 times this recipe to feed the group. Everyone loved it. And best of all, my husband said it was better than Boston Market’s!!! Will make every year from here on out. Kudos to you!!! Thank you so much!

    I prepared this recipe and I have to say it was very delicious. It was very easy to make as well. I loved how easy the jackets came off after baking vs boiling the potatoes.
    I will be using this recipe every year because it is easy and delicious !
    Thank you so much !
