Canned Sweet Potatoes vs. Canned Yams?

What’s the difference between canned yams and canned sweet potatoes in cooking? Both are used interchangeably in most recipes. Yams are dry and starchy with white flesh and a rough, brown exterior similar to a regular potato. Sweet potatoes are moist with orange, purple, or white flesh and have smooth, thin, orange skins.

Ingredients and Variations

Easy to find ingredients are all you need to create this cozy classic!

Yams – Canned sweet potatoes need to be drained before use. Want to use fresh? Simply peel, cut up, and boil 2-3 sweet potatoes (or yams) and mash them before starting in Step 3.

Dairy – Heavy cream and real butter complement the sweet flavors of the yams. Make a dairy-free casserole using coconut oil and coconut cream, oat milk, or soy milk. Brown sugar can be replaced with maple syrup, honey, or a sugar-free alternative of your choice.

Toppings – The mini marshmallows are a must-have for sweet potato casserole, but you could simply drizzle the top with maple syrup. Pecans or walnuts bring crunch to the creamy texture, a nut-free option would be sunflower or pumpkin seeds.

Variations – For a sweeter casserole, stir in one cup of canned pumpkin or and a dash of vanilla extract (or bourbon or rum) along with a pinch of nutmeg or allspice. For a savory version, omit the marshmallow and nuts for bacon bits and chopped sage for a more savory topping.

For Added Crunch!

Toasting nuts or seeds in a dry saute pan before using keeps them extra crunchy and intensifies their flavor!

How to Make Sweet Potato Casserole

Mash drained yams with remaining ingredients (except toppings).

  1. Spread yam mixture into a casserole dish.
  2. Prepare topping and sprinkle equally over the yams.
  3. Bake (per recipe below) until heated through and the marshmallows are lightly browned.
  4. Let casserole rest 5 minutes before serving.

Quick Tips for Success!

Make ahead by assembling the casserole and baking it without the topping. Then simply add the topping and reheat before serving!

Serving and Storing Sweet Potato Casserole

Keep leftover canned sweet potato casserole in an airtight container in the refrigerator for up to 4 days. Leftovers can be frozen in a freezer-safe container for up to six months, (best enjoyed within 2 months, however). Leftovers can also be added to potato pancakes, muffins, smoothies, or a pumpkin pie for extra flavor and nutrition.
