This casserole balances silky, spiced mashed yams with a crispy, buttery topping that adds texture in every bite. Canned yams let you skip peeling and boiling, so the dish comes together fast.

A touch of brown sugar and vanilla brings warmth without making it taste like dessert. The result is familiar and nostalgic, but still light enough to sit comfortably alongside roasted meats, greens, and stuffing.

What You’ll Need

  • 2 cans (29 ounces each) of cut yams, drained well
  • 4 tablespoons unsalted butter, melted (plus more for greasing the dish)
  • 1/3 cup brown sugar (light or dark)
  • 1/4 cup granulated sugar (optional for extra sweetness)
  • 1/3 cup milk (or half-and-half for richer texture)
  • 2 large eggs, lightly beaten
  • 1 teaspoon vanilla extract
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • 1/2 teaspoon salt
  • Optional: 1/4 teaspoon ground ginger for a gentle lift

Topping options (choose one or mix):

  • Pecan streusel: 1 cup chopped pecans, 1/2 cup brown sugar, 1/2 cup all-purpose flour, 4 tablespoons melted butter, pinch of salt
  • Marshmallow topping: 3–4 cups mini marshmallows
  • Oat crumble: 3/4 cup rolled oats, 1/3 cup brown sugar, 1/3 cup flour, 4 tablespoons melted butter, pinch of cinnamon

  1. Heat the oven: Preheat to 350°F (175°C). Lightly grease a 9×13-inch baking dish with butter or nonstick spray.
  2. Drain and mash: Drain the canned yams thoroughly.

    Add them to a large bowl and mash until mostly smooth. A few small chunks are fine for texture.

  3. Blend the base: Stir in melted butter, brown sugar, granulated sugar (if using), milk, eggs, vanilla, cinnamon, nutmeg, salt, and ginger (if using). Mix until fully combined and creamy.
  4. Adjust sweetness: Taste the mixture.

    If you prefer a less sweet casserole, reduce or skip the granulated sugar. For a richer flavor, use half-and-half.

  5. Make the topping: For pecan streusel or oat crumble, combine all topping ingredients in a bowl and mix with a fork until crumbly. If using marshmallows, set them aside for now.
  6. Assemble: Spread the yam mixture evenly in the prepared baking dish.

    Sprinkle the streusel or crumble evenly over the top. If using marshmallows, you will add them later.

  7. Bake: Bake for 25–30 minutes if using a streusel or crumble topping, until the edges are bubbly and the top is lightly golden.
  8. Marshmallow method: If topping with marshmallows, bake the casserole without topping for 20–25 minutes. Remove from the oven, scatter mini marshmallows on top, and return to the oven for 8–10 minutes, until golden and puffed.
  9. Rest and serve: Let the casserole rest for 10 minutes to set.

    Serve warm.

Storage Instructions

  • Refrigerate: Cool completely, cover tightly, and refrigerate for up to 4 days.
  • Reheat: Warm in a 325°F oven, covered with foil, for 15–20 minutes. Uncover for the last 5 minutes to crisp the topping. Microwave in short bursts for single portions.
  • Make-ahead: Assemble the yam mixture and streusel separately up to 2 days ahead.

    Refrigerate both, then top and bake just before serving. If using marshmallows, add them during the last 10 minutes of baking.

  • Freezing: Freeze the baked casserole (without marshmallows) for up to 2 months. Thaw overnight in the fridge and reheat in the oven.

    Add fresh marshmallows during reheating if desired.

Why This is Good for You

Sweet potatoes are naturally rich in beta-carotene, which your body converts to vitamin A to support eye and immune health. They also provide fiber, which helps you feel satisfied and supports digestion. Using nuts or an oat topping adds healthy fats and extra texture.

You’re getting comfort food with real nutrients, not just empty sweetness.

What Not to Do

  • Don’t skip draining the yams. Excess liquid can make the casserole watery and bland.
  • Don’t overmix after adding eggs. Stir until just combined to avoid a gummy texture.
  • Don’t overload the sugar. Canned yams often contain syrup. Taste the mash before adding extra sugar.
  • Don’t add marshmallows too early. They’ll burn before the casserole sets. Add near the end.
  • Don’t bake uncovered for too long. If the topping browns too quickly, tent with foil.

Recipe Variations

  • Maple Pecan: Replace brown sugar with pure maple syrup in the mash (about 1/4 cup) and use the pecan streusel topping.
  • Orange Zest Lift: Add 1 teaspoon orange zest and 1 tablespoon orange juice to the mash for a bright, citrusy note.
  • Spice Lovers: Use pumpkin pie spice (1–1.5 teaspoons) instead of cinnamon and nutmeg.
  • Savory Twist: Reduce sugar by half, add 1/2 teaspoon smoked paprika and a pinch of cayenne, and top with toasted pecans and a light sprinkle of flaky salt.
  • Dairy-Free: Use coconut milk or almond milk and dairy-free butter.

    The coconut milk adds a subtle, creamy sweetness.

  • Gluten-Free: Use a gluten-free flour blend in the streusel or skip flour entirely and double the nuts and oats.
  • Single-Serve Cups: Bake in greased muffin tins for 15–20 minutes. Add mini marshmallows in the last few minutes for easy portioning.

FAQ

Can I use fresh sweet potatoes instead of canned yams?

Yes. Peel and cube 3 pounds of sweet potatoes, boil until tender, and mash.

You may need a touch more milk to reach a creamy consistency. The rest of the recipe stays the same.

Are canned yams and sweet potatoes the same thing?

In most U.S. grocery stores, “canned yams” are actually sweet potatoes. True yams are different, but they’re rarely used in this kind of casserole.

For this recipe, canned yams labeled in syrup or water both work.

How do I cut the sweetness?

Drain well, rinse the yams briefly if they were packed in heavy syrup, and reduce or skip the added granulated sugar. A pinch of salt and a little cinnamon helps balance the flavor.

What size pan should I use if I halve the recipe?

A 9-inch square or an 8×8-inch pan works well. Start checking for doneness around 18–22 minutes, especially if using a streusel topping.

Can I make this without eggs?

Yes.

Use 2 tablespoons cornstarch or 2 tablespoons maple syrup plus 1 tablespoon cornstarch to help the casserole set. Bake until the center looks just firm.

How do I keep the topping crunchy?

Let the casserole rest uncovered for 10 minutes after baking. If reheating, remove foil for the last few minutes to crisp it back up.

Is this good for a potluck?

Absolutely.

It travels well, reheats easily, and suits a wide range of tastes. Bake in a disposable pan, bring foil for reheating, and add marshmallows on-site if using.

In Conclusion

This Canned Yam Sweet Potato Casserole Delight is warm, creamy, and reliably delicious, with the kind of nostalgic flavor that makes people go back for seconds. It’s easy to assemble, flexible with toppings, and friendly to make ahead.

Whether it’s a holiday spread or a cozy Sunday dinner, this dish brings comfort without the stress. Keep the ingredients on hand, and you’ll always have a crowd-pleaser ready to go.
