Tips for one pot/ one dish simple sweet potato casserole recipe

  • If you have any leftover mashed sweet potatoes, just use those in this recipe and omit all the spices, butter, honey and milk I have listed below. Just spread the sweet potato layer in a pan, top it off with marshmallows and pecans and bake.
  • Recipe can easily be doubled or halved to serve a big or small crowd.
  • Adjust the amount of spices, based on your preference.
  • Adjust the amount of honey, based on your preference. If you like your casserole very sweet, add more honey.
  • Instead of pecans, any other nuts of your choice can be used.
  • The amount of milk can be adjusted based on how thin or thick you like your mashed potatoes. Everyone has their own preference. I recommend that you start off by adding a small amount first and then add more, as necessary.
  • To make these potatoes super creamy, use half and half or a combination of whole milk and heavy cream. I don’t recommend using fat free milk or 2% milk because it doesn’t make this casserole as creamy as I would like.
