Introduction
Sweet Potato Casserole with Canned Yams is a quick and comforting dish perfect for holidays or any cozy meal. Using canned yams makes preparation simple while still delivering rich, sweet flavors topped with gooey marshmallows.

Ingredients
- 58 oz canned yams (2 cans, 29 oz each)
- ¼ cup brown sugar
- 1 tbsp pure maple syrup
- 1 tsp ground cinnamon
- 3 tbsp butter
- 2 cups mini marshmallows
Instructions
- Step 1: Preheat the oven to 350℉ and grease a casserole dish with butter or non-stick spray.
- Step 2: Drain the canned yams, reserving 2 tablespoons of the juice in case the casserole seems dry later.
- Step 3: In a large bowl, mash the yams until smooth.
- Step 4: Add the brown sugar, maple syrup, and cinnamon to the yams, mashing until well blended. Add some reserved juice if the mixture is too dry.
- Step 5: Spoon the sweet potato mixture into the prepared dish and smooth the top evenly. Dot with butter on top.
- Step 6: Bake for 30-40 minutes, or until heated through.
- Step 7: Sprinkle the mini marshmallows evenly over the casserole and bake for another 5-10 minutes, until golden brown. You can broil for 1-2 minutes at the end for extra toasting if desired.
Tips & Variations
- Use pecans or walnuts mixed into the top for added crunch and flavor.
- Substitute maple syrup with honey or molasses for a different sweet note.
- If you prefer a thicker texture, drain the yams more thoroughly or cook the mixture a few minutes longer before baking.
Storage
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350℉ until warmed through to retain the crispy marshmallow topping. Avoid microwaving to keep the texture intact.

FAQs
Can I use fresh sweet potatoes instead of canned yams?
Yes, you can substitute with cooked, mashed fresh sweet potatoes. Roast or boil them until tender before mashing and proceeding with the recipe.
How do I prevent the marshmallows from burning?
Keep a close eye during the final broiling step and remove the casserole as soon as the marshmallows turn golden brown. You can also bake them at a lower temperature for longer if preferred.

Ingredients
Sweet Potato Mixture
- 58 oz canned yams (2 cans, 29 oz each)
- ¼ cup brown sugar
- 1 tbsp pure maple syrup
- 1 tsp ground cinnamon
- 3 tbsp butter
Topping
- 2 cups mini marshmallows
Instructions
- Preheat and prepare dish: Preheat your oven to 350℉ (175℃). Grease a casserole dish with butter or non-stick spray to prevent sticking.
- Drain and reserve juice: Drain the canned yams thoroughly, reserving 2 tablespoons of the liquid in case the casserole seems dry during mixing.
- Mash yams: Transfer the yams into a large mixing bowl and mash them until smooth or your desired consistency.
- Add flavorings and blend: Mix in the brown sugar, pure maple syrup, and ground cinnamon. Continue mashing until all ingredients are thoroughly blended. If the mixture feels too dry, add some of the reserved juice gradually to soften.
- Arrange in baking dish: Spoon the sweet potato mixture evenly into the prepared casserole dish, smoothing the top with a spatula. Dot the surface with the 3 tablespoons of butter.
- Bake the casserole: Place the casserole in the preheated oven and bake for 30 to 40 minutes until the sweet potato mixture is heated through and starting to bubble.
- Add marshmallow topping: Remove the casserole from the oven and evenly sprinkle the 2 cups of mini marshmallows over the top. Return it to the oven and bake for an additional 5 to 10 minutes until the marshmallows are golden brown and melted.
- Optional broil: For an extra golden and toasted marshmallow topping, you may broil the casserole for 1 to 2 minutes watching closely to prevent burning.
Notes
- Using canned yams saves time and effort but make sure to drain thoroughly.
- If you prefer a less sweet casserole, reduce the amount of brown sugar or maple syrup.
- For a richer flavor, use real butter rather than margarine or spray.
- Broiling is optional and should be watched carefully as marshmallows can burn quickly.
- This casserole can be prepared a day ahead and reheated before serving.
