This dish is crazy easy to make and on Thanksgiving day, we need easy!

Most importantly I’m thankful my mother in law shared the recipe with me years ago. It became an instant Thanksgiving hit for our family.

recipe steps

  • while the potatoes are boiling, prepare the crumble mixture. Use gluten free rolled oats for this recipe. Place the oats, all purpose gluten free flour, brown sugar, and cinnamon in a bowl. Cut in the butter with a pastry blender. After your crumble is well mixed, separate out 1 cup and set aside.
  • next chop the cranberries; I find it fastest to use my pampered chef food chopper.  This is my kids’ favorite kitchen gadget. They beg to use it and with a fun recipe like this sweet potato bake, they can. I use my food chopper on a weekly basis for recipe projects. It’s one of my favorite kitchen gadgets and time savers!
  • when the sweet potatoes are tender, drain the water. Add the chopped cranberries and crumble mixture to the sweet potatoes. Once the mixture is well combined place it into an ungreased 1.5 quart casserole dish. Sprinkle the top of the casserole with the remaining 1 cup crumble mixture.
  • then bake uncovered at 350 F for 30 minutes. Be prepared… your house is about to smell like the most amazing Bath & Body fall candle. The smell alone will put you in a food coma. Your Thanksgiving guests all will be asking what is that amazing smell?!
  • after 30 minutes remove the dish from the oven and cover with a single layer of marshmallows. Return to the oven for 10-12 minutes. I beg you to set a timer. I have seen someone get distracted with other Thanksgiving dishes and forget the sweet potato bake in the oven. When they did open the oven door, the marshmallows were on fire, y’all. We had a great laugh, scraped off the burned marshmallows, and put on fresh ones. Just set a timer.
  • mini marshmallows–for a “free from” brand check out Dandies
  • lastly your sweet potato bake is ready to eat when it leaves the oven.

This sounds wonderful! Can you sub tapioca flour or gluten free all purpose flour in place of the almond flour? My LO has an almond allergy.

Lauren I'm so glad you reached out. Yes absolutely you can substitute fro the almond flour. I'd suggest a gluten free all purpose flour first. Enjoy and Happy Thanksgiving. Jill
