This holiday classic transforms canned yams into a creamy, spiced masterpiece. Topped with golden marshmallows, it’s the perfect side for your festive table.

Simple prep and 30 minutes in the oven deliver a dish that’s both nostalgic and effortless. The sweetness of the yams pairs beautifully with warm spices and a gooey, toasted topping.

Ingredients for Sweet Potato Casserole Recipe with Canned Yams

Pantry staples plus a few extras create this nostalgic holiday side dish.

The canned yams are non-negotiable here—Bruce’s or Del Monte work best. Look for yams packed in syrup for natural sweetness (drain well before mashing). The evaporated milk adds richness without thinning the texture. Carnation brand is reliable, but any store brand works. Butter quality matters—Kerrygold or Organic Valley if you’re splurging (worth it for holidays).

No evaporated milk? Whole milk plus a tablespoon of flour thickens it up. Swap pecans for walnuts or almonds if that’s what you’ve got. Mini marshmallows melt better than regular, but large ones cut in half work too. The spices can be adjusted—add a pinch of cloves or allspice if you’re feeling fancy. Eggs bind everything, but flax eggs (1 tbsp ground flax + 3 tbsp water per egg) work for a vegan twist.

Assemble ahead and refrigerate overnight—24 hours max. Bake straight from the fridge (add 5-10 minutes to cook time). Leftovers keep 4-5 days in the fridge, but the marshmallows soften. Reheat covered to prevent drying out.

Step-by-Step Instructions for Sweet Potato Casserole With Canned Yams

This method delivers that classic holiday texture with minimal effort and maximum flavor.

Step 1: Prepare and Season the Yam Base

Drain the 40 oz Canned Yams thoroughly in a colander, pressing gently to remove excess liquid. Transfer to a large mixing bowl and mash until smooth—I find a potato masher works best for this.

Add the 0.5 cup Unsalted Butter (melted), 0.75 cup Granulated Sugar, 2 tsp Vanilla Extract, 1 tsp Ground Cinnamon, 0.25 tsp Ground Nutmeg, and 0.5 tsp Salt. Stir until fully combined and the mixture takes on a vibrant orange hue. The spices should be evenly distributed with no visible streaks.

Step 2: Create the Creamy Binding Mixture

In a separate bowl, whisk the 2 whole Large Eggs until frothy. Slowly pour in the 12 oz Evaporated Milk while continuing to whisk—this prevents the eggs from scrambling when they meet the warm yam mixture.

Gradually incorporate the egg mixture into the yams, stirring constantly. You want a smooth, pudding-like consistency that holds its shape when scooped. If it seems too thin, let it sit for 5 minutes—the yams will absorb some of the liquid.

Step 3: Assemble and Bake the Casserole

Transfer the mixture to a greased 9×13-inch baking dish, spreading it evenly with a spatula. The surface should be smooth with no lumps. Bake in a preheated 350°F oven for 25-30 minutes until the edges start to pull away from the dish and the center is set but still slightly jiggly.

This initial bake firms up the base so it can support the topping. Don’t overbake at this stage—the casserole will continue cooking under the marshmallows.

Step 4: Add the Marshmallow-Pecan Topping

In a small bowl, toss the 10 oz Mini Marshmallows with the 0.5 cup Chopped Pecans and 0.25 cup Light Brown Sugar. The brown sugar adds a caramelized depth to the topping.

Sprinkle this mixture evenly over the baked yam layer, covering the surface completely. Return to the oven and bake for another 10-12 minutes until the marshmallows are golden brown and puffed, with some edges slightly toasted. Watch closely during this final bake—marshmallows can go from perfect to burnt quickly.

Step 5: Rest and Serve

Remove from the oven and let the casserole rest for 5-10 minutes before serving. This allows the topping to set slightly so it doesn’t slide off when portioned.

The finished dish should have a creamy, spiced yam base with a crisp, gooey marshmallow-pecan topping. Serve warm while the marshmallows are still soft and stretchy. The contrast between the smooth filling and the textured topping is what makes this casserole a holiday favorite.

Wine and Beer Pairings for This sweet potato casserole recipe with canned yams

White Wine Pairings

A slightly off-dry Riesling from Germany or Washington state balances the sweetness beautifully. Its crisp acidity cuts through the richness while complementing the cinnamon and nutmeg. I love Chateau Ste. Michelle for its consistent quality and affordability. 🍷

Dessert Wine Options

For a special occasion, try a Moscato d’Asti from Italy. The light effervescence and peach-apricot notes enhance the marshmallow topping. Saracco Moscato d’Asti is my go-to at around $15 per bottle.

Red Wine Choices

If you prefer red, opt for a fruity Pinot Noir from Oregon. The bright cherry flavors won’t overpower the casserole. Meiomi offers a reliable, food-friendly option that’s widely available.

Beer Pairings

A malty amber ale like Fat Tire from New Belgium Brewery complements the caramelized sweetness. The toasted malt notes mirror the brown sugar in the topping. For craft lovers, Bell’s Amber Ale is another excellent choice. 🍺

Non-Alcoholic Options

Sparkling apple cider provides the same effervescence as wine without alcohol. Martinelli’s is my favorite brand. For a warmer option, spiced chai tea echoes the cinnamon and nutmeg flavors perfectly.
