What’s the Difference Between Yams and Sweet Potatos?
Yams and Sweet Potatoes are often used interchangeably.
While they’re similar, they look and taste different. Yams are actually a variety of sweet potatoes.
Yams have a white, cream or purple-colored flesh and the skin is usually brown, strong, and bark-like.
While sweet potatoes have orange or pale-colored flesh and can have either golden skin or red skin.
The reason people get so confused easily is because they tend to think sweet potato means orange inside.
Grocery stores don’t make it any easier either. They tend to mislabel the two or swap the labels without even realizing it. Most grocers tend to sell sweet potatoes and not yams.
Can You Make This Ahead Of Time?
What’s beautiful about this recipe is that you certainly can prep it ahead of time. You can make it all in the Instant Pot and store it in the Mason Jars. Wait for the baking and marshmallow topping until closer to when you’re ready to serve and enjoy it.
We recommend prepping this no longer than 48 hours in advance and make sure you cover and refrigerate the casserole recipe.
When you’re ready to bake this recipe and add the marshmallow topping, let the casserole warm up to room temperature before baking. Otherwise, add a few more minutes to cook time.Feel free to adjust the amount of spices you use in this recipe to suit your taste.
Can You Freeze Sweet Potato Casserole?
Making this mini sweet potato casserole is actually the perect size for freezing. Don’t add the marshmallows until you’re ready to bake and enjoy it. Just cook the sweet potatoes in the Instant Pot and then freeze in a bag or appropriate Mason Jars that are safe for freezing.
Make sure to add it to your FREEZER INVENTORY list.
Can You Use Canned Sweet Potatoes?
Yes, you sure can used canned ones. You will need quite a few cans. We recommend not including the liquid in the Instant Pot recipe.
How Do You Store This Casserole?
If you’re not going to enjoy it all at once, you can cover it and put it in the refrigerator for up to 2 days. We recommend using an air tight container to store it in.
