Marshmallow Sweet Potato Casserole (for Passover)




About: My name is Randy and I am a Community Manager in these here parts. In a previous life I had founded and run the Instructables Design Studio (RIP) @ Autodesk's Pier 9 Technology Center. I'm also the author ...

There are really only two things I like about Passover; the first thing being sitting on pillows and the second being the marshmallow sweet potato dish that someone in my family inevitably makes. Unleavened bread and brisket are really not my thing.

Any which way, being a safe 3,000 miles away from my family, when Passover rolled around this year, I took it upon myself to make my own sweet potato casserole.

Follows are steps you can take to make your own. Oh rapture!

Step 1: Go Get Stuff.


5 large sweet potatoes (or two cans of yams)
1/4 stick of unsalted butter and/or maple syrup equivalent
1 tsp brown sugar
5 shakes of ground cinnamon
2 tsp vanilla
1 bag of little marshmallows
1 bag of large marshmallows


- casserole dish
- sharp knife
- spoon
- measuring spoons
- aluminum foil

Step 2: Cook the Sweet Potatoes

Wash the sweet potatoes off if you care to do so.

Wrap them in tin foil.

Preheat the oven to 350 degrees.

Put them in the oven for an hour to an hour and a half. Take them out only when they are soft all the way through. You can tell when this is by taking one out and sticking a knife through it. If the knife slices through easily, then it is obviously soft all the way through.

Step 3: Get the Scoop.

When the sweet potatoes are done cooking, take off the tin foil, cut them in half and scoop out the insides into your casserole dish.

Step 4: Mix in Some Flava'.

Once all your sweet potatoes have been scooped out, you are going to want to mash the following ingredients into your casserole:

- ground cinnamon
- brown sugar
- butter and/or syrup (for moisture)
- vanilla

Mash them in one at a time. Continue mashing until all the big chunks of potato have been broken up. It should be relatively creamy.

Step 5: Prepare to Cook.

Start preheating the oven to 350 degrees.

Take a handful or two of small marshmallows and mix them in to the casserole until they're spread throughout (see secondary picture).

Once the casserole is ready and the oven is ready, put one inside the other. I'll let you guess which you put inside which.

Any which way, cook your casserole for a half hour or until it is heated through. You can usually tell when it's ready is because the marshmallows will be melted into the potato.

Step 6: Top It Off.

After it has been heated through, it is time for the best part.

Take it out of the oven and cover the top of the casserole with the large marshmallows. Don't worry about being stingy.

Put it back in the oven.

Crank the oven up to 450 degree and cook it until the marshmallows start to brown and swell.

Step 7: Cool and Serve.

Once melted, take your casserole out of the oven and let it cool for 5 to 10 minutes. This should enough time for the marshmallows to stop swelling and settle down.

    Wow! Coming from Sweden, mixing marshmallows with sweet potato seems totally wild!
    I was intrigued to read your recipe and I really want to try it now.

    I just have to ask. Is this meant as a dessert or something to be used as a side-dish for a main-course? Thanks in advance!

    Generally, it's considered a side dish. I know it's sweet, but it's commonly considered a "vegetable side dish". Of course, as sweet as it can be, it could be used as a dessert. The poster's use of the mini-marshmellows in the actual sweet potato mix is not common and could make it a bit sweeter, but the best part of a sweet potato casserole is the marshmellows. It's yummy!!!

    I feel that I must comment on marshmallows...the ones pictured here are made with gelatin which is made from the leavings from pork and other meat... which might be okay with a Parve meal, but not so much for Pesach. So instead, spend the extra (lots extra!) shekels and get the "kosher for Passover" marshmallows. Your right in all other ways, a GREAT way to eat your sweets! thanks.

    Oh yeah, I should have mentioned that. I think unsalted soy butter is okay though, but that is where the maple syrup comes in. You can replace the butter with the maple syrup.

    I think it's good to have a little fat- soy margerine, as you suggest- for texture.

    If it's for Passover, be sure to use kosher marshmallows. Some marshmallows are made from animal gelatine... Being only vaguely/slightly Jewish, I don't recall a lot of traditional meals from Passover celebrations, especially WRT main courses. My favorite thing was the horossis (sp? ground up apples and almonds and cinnamon...)
