Sweet Potato Marshmallow Casserole

A classic Thanksgiving side dish is this sweet potato casserole with apples and pecans. These candied yams are topped with mini marshmallows at the end for a toasty, gooey, and sweet treat.  The fresh apples, crunchy pecans, and savory canned yams all come together for the perfect side dish with turkey, chicken, or pork. As a child (and still today) marshmallow candied yam casserole is my favorite part of the meal at Thanksgiving. 

As someone that does not like pumpkin, this was often my dessert as well.  It is like a crustless apple sweet potato pie that you just cannot get enough of.  My mom makes it every year and often reminds me that I even dreamed about it when I was 5. In kindergarten, a cookbook was created by the teacher asking us all to tell her how to make our favorite recipe. Mine was this but back then at age 5 I called it “Goodie Casserole” and I said to cook it at 17°.  Well, rest assured I know how to cook this now and it’s not frozen at 17°.

Ingredients for Sweet Potato Casserole

For this Thanksgiving sweet potato casserole, you will need mostly pantry items but also some fresh ones.  You can shop for these items before the Thanksgiving grocery store madness begins, which is a life-saver for many who hate the crowds and lines.   For this holiday recipe, you will need apples, pecans, brown sugar, cinnamon, butter, canned yams, and of course mini marshmallows.  Use your favorite apples to make candied yams but I recommend something more on the tart side to balance the sweetness from the brown sugar and marshmallows.

Sweet potatoes and yams are actually different vegetables. Learn all about the difference between a sweet potato and a yam. However, the canned yams we find in America are often actually sweet potatoes.  So I will use the terms interchangeably here.  This is made with canned yams that have been drained and then the rest is added to the casserole before baking. The most common brands will be Bruce’s or Princella canned sweet potatoes/yams that are best to use for candied yams with marsmallows. You can use fresh sweet potatoes too that you have cooked until soft in the oven, microwave, Instant Pot, or Crock-Pot.

How to Make Sweet Potato Casserole

There is not much to prepping this quick & easy candied yam casserole recipe.  To make this, start by preheating the oven to 350°.  Also, spray an 8×8″ casserole dish with nonstick spray.

While the oven warms up, core and chop up the apples. You want chunks about 1/2″ in size. You can peel them or leave the peel on; however, you like baked apples will work in this recipe.  Now, chop the pecans if they are not already in pieces. You want big chunks and some are ok if they are in whole halves.

Drain the yams and add them to the casserole dish. There will be large & small chunks in the can. Use a knife to cut the bigger ones, you want the chunks to be about 1-2″ in size. They do not need to be all the same exact size just keep them in that range.
 
Once the yams are ready and in bite-sized chunks, sprinkle the apple chunks & pecan pieces over the yams in an even layer.  Next, sprinkle on the brown sugar and cinnamon evenly over all the ingredients. Lastly, dice the butter into smaller chunks to get about 12 small pieces. Evenly distribute the small butter pats over the top of the entire casserole dish.

How Long & Temperature to Cook Candied Yam

NOTE – **  You can also just bake the marshmallows on instead of a toasted layer as seen here. To do that, simply add the marshmallows now for the baking process, instead of broiling at the end.**

Bake on the center rack in the oven at 350° for 20-25 minutes. The apples should be soft and the brown sugar juices should be bubbling. Remove the casserole dish using an oven mitt from the oven. Now is the time for that magical marshmallow layer.  Carefully sprinkle the mini marshmallows over the top of the casserole.  Put as many as you want but at least half the bag of the 10oz size.

Toast the Marshmallows on Sweet Potato Casserole

To get that roasted marshmallow goodness, you will be broiling them.  So at this time, change the oven to broil, on low. On a top rack of the oven place the casserole to broil the marshmallows slowly. You want it to be at least 4-6″ from the top broiler element in your oven.

 

DO NOT STEP AWAY, leave the oven door ajar and watch the marshmallows as they toast. You may need to rotate the pan to get an even toast. Once they are to your desired doneness, remove using an oven mitt.  We love them well done and the marshmallows roasted to a dark brown almost burnt texture.  We are that family that loves when we are roasting marshmallows over a campfire and they catch on fire.  Oh sooo crispy on the outside and gooey marshmallow heaven on the inside.

Smoked Beef Short Ribs
The best way to make short ribs in my mind is in the smoker.  The low and slow method of smoking meat breaks down the meat and renders the fat for the most delicate fall-off-the-bone short ribs you will have ever had.

This casserole can be stored in the refrigerator or freezer easily.   To store sweet potato casserole that has already been cooked with the toasted marshmallow topping, simply cover the casserole with foil.  Place it in the refrigerator and store for up to 5 days.

You can freeze both leftover and made-ahead marshmallow sweet potato casserole. To freeze leftovers that have already been cooked, place them in an air-tight container and freeze for up to a month. To make this ahead of time to freeze and then cook later, it will be different.  Making this sweet potato casserole for meal planning is easy.  Combine all the ingredients in the casserole dish except the mini marshmallows.  Place a lid on the casserole dish or wrap in plastic wrap and then foil to make it air-tight. You can freeze this for up to 3 months.  When you want to cook frozen sweet potato casserole, defrost it in the refrigerator for 2 days.  Once thaw, bake per the recipe and top with the marshmallows.
