Easy Sweet Potato Casserole With Streusel Topping
This easy sweet potato casserole with streusel topping is the perfect dish for potlucks and family gatherings. This is my most requested dish for every holiday. I mainly make this for Thanksgiving but I have been known to add it to our Christmas menu.
The topping is made with pecans and shredded coconut. No marshmallows in this sweet potato casserole recipe.

One year, I decided I wasn’t going to make it. (This sweet potato casserole has lots of calories.) You should have seen the reaction from my family. Oh, my! The family was horrified. They said it is just one time a year. Make the casserole, they said. And every year, I do. It’s a splurge but so worth it.
How To Cook Sweet Potatoes In The Instant Pot
TIP: Use your Instant Pot to cook the sweet potatoes for this recipe.
I like to use my Instant Pot to cook the sweet potatoes. This is how I cook potatoes for potato salad, too.
All you have to do is peel and cube the sweet potatoes.
Place them in a steamer basket.
Add one cup of water to the inner pot of the Instant Pot. Put the steamer basket inside the inner pot.

Put the lid on the Instant Pot. Lock the lid. Point the valve to sealing. Using the manual or pressure cook button, set the timer for 10 minutes on high pressure.
When the timer is up, do a quick release to depressurize the Instant Pot. Continue with the rest of the recipe.
An advantage to cooking with an Instant Pot is that there isn’t any boil over.

Expert Tips For The Best Sweet Potato Casserole
- Make ahead.
- This is a very easy casserole to put together. To save time, this dish can be prepared the day before and stored in the refrigerator. Then baked the following day.
- Add some spice.
- If you like traditional fall spices, you could add 1/2 teaspoon of ground nutmeg, cinnamon or pumpkin pie spice to the sweet potato filling.

Sweet potato casserole has been a favorite for about 15 years now.
My question is this: The thickness of my casserole turns out very shallow in the 9×13 pan and nothing like the pictures above. If I wanted to make it taller, per say, can I use a 9×11 or 8×8? What would be the temp and baking time? If so, should I wait a little while before adding the topping?
Thanks!
I have made this in a 9 x 9 inch pan using the same time and temperature with less sweet potatoes. I always add the topping at the same time. Hope this helps.
I’m assuming you’re using less than two pounds of sweet potatoes. The casserole will puff up some due to the eggs.
