Sweet Potato Casserole - Best of Both Worlds

🔑 Key to Success #1 – Making Everyone Happy

On one side, you’ve got the people who like the pecan topping.

On the other side, you’ve got the people who want marshmallows.

It’s time to bring everyone together at the table and make a Sweet Potato Casserole that has a little bit of something for everything.

Sweet Potato Casserole With Pecan Topping and Marshmallow Rows

This Sweet Potato Casserole recipe lets the pecan topping and the marshmallow topping co-exist side by side in neat little rows.

That way everyone can get what they want and nothing they don’t.

And hey, if you love both the pecan topping and marshmallows, you’re in luck because you can have both on one plate.

🔑 Key to Success #2 – Separating the Pie from the Casserole

Personally, I love sweet potato-anything but I want to make sure my Sweet Potato Pie and my Sweet Potato Casserole have a different taste and texture.

For this reason, I do not put eggs or cinnamon or other pie spices in my Sweet Potato Casserole.

Making the Sweet Potato Casserole without eggs and without cinnamon lets the sweet potato flavor really shine.

It gives a smooth, silky texture to the sweet potatoes.

🔑 Key to Success #3 – Striping the Casserole

I like to put my topping into wide diagonal stripes because that makes it easier for your guests to scoop out exactly which topping – or toppings they want without having to dig into the middle of the casserole dish.

The pecan topping needs to be baked with the casserole.

I sprinkle the pecan topping in place first before putting the casserole into the oven to bake.

Then when I have about 10 minutes left on the timer, I take the casserole out and add the marshmallows over the uncovered sweet potatoes.

Finally, put it back into the oven to finish baking.

You’ll want to watch your marshmallows closely to make sure they don’t get overly brown.

If you’d like, you can also stick them under the broiler for a minute or two instead.

But like I said, watch it very carefully so that it doesn’t burn!

A few minutes should be plenty.
