Ingredients for sweet potato casserole recipe without milk

Sweet, creamy, and dairy-free—this casserole delivers holiday comfort without milk or butter.

The sweet potatoes are the foundation, so choose firm, vibrant orange ones—the deeper the color, the sweeter the flavor. Costco and Trader Joe's often have the best organic varieties, but any grocery store will work. For the coconut milk, full-fat canned versions (like Thai Kitchen) give the richest texture—skip the light versions. The brown sugar should be packed firmly; don't scoop it loosely or you'll end up with less sweetness. Pecans? Buy them raw and toast them yourself—store-bought toasted ones lose their crunch fast.

No vegan butter? Coconut oil or olive oil works in a pinch, though the flavor will differ slightly. Substituting maple syrup? Agave nectar at the same amount keeps it dairy-free. The cinnamon and ginger are non-negotiable for that classic casserole warmth, but if you're out of one, nutmeg or allspice at half the amount can stand in. For the pecan topping, walnuts or almonds work if pecans are pricey—just adjust the toast time. And if you can't find vegan butter, melted coconut oil in the topping adds richness without dairy.

Store leftovers covered in the fridge for up to 5 days, though it reheats beautifully—just cover with foil to prevent drying. The pecan topping stays crispy for 3 days if kept airtight. For make-ahead prep, assemble the casserole (without baking) up to 24 hours ahead—the flavors meld even better overnight. Freeze unbaked portions for 3 months; thaw in the fridge before baking. The coconut milk separates when chilled? Just whisk it back together before using—it's totally normal.

Step-by-step instructions for sweet potato casserole without milk

This dairy-free version delivers rich, velvety texture using coconut milk and a perfectly crisp pecan topping.

Preheat oven to 375°F. Toss the peeled and cubed 3 lb sweet potatoes with 2 tbsp coconut oil, 2 tsp cinnamon, and 0.5 tsp salt. Spread evenly on two rimmed baking sheets and roast for 25-30 minutes until fork-tender with slightly caramelized edges.

Here's the thing—roasting develops natural sweetness better than boiling. You'll know they're done when a knife slides in easily and the edges look golden brown. Let them cool slightly before mashing to prevent a gummy texture.

In a large mixing bowl, combine the cooked sweet potatoes with 13.5 oz full-fat coconut milk, 0.75 cup brown sugar, 0.5 cup unsalted butter, 1 tsp vanilla extract, and 1 tsp ground ginger. Mash with a potato masher until smooth but slightly textured—you want some body to hold the swirl shape.

For the swirl effect, divide the mixture into two equal portions. In one portion, stir in 0.25 cup maple syrup until fully incorporated. This extra sweetness creates the beautiful marbled pattern when swirled.

Transfer half of the plain sweet potato mixture to a greased 9x13-inch baking dish. Spread evenly with a spatula. Then take the maple-infused portion and dollop spoonfuls over the first layer. Using the tip of a knife, gently swirl the two mixtures together in a circular motion to create that classic marbled effect.

Don't overmix—just enough to create pretty patterns. The contrast between the light and dark swirls makes this casserole visually stunning. Smooth the top with the back of a spoon for an even surface.

In a small bowl, mix 1.5 cups chopped pecans, 0.25 cup all-purpose flour, 1 tbsp brown sugar, and 0.25 tsp cinnamon. Spread this mixture evenly over the top of the casserole, pressing down gently to ensure good contact with the coconut layer.

For extra crunch, toast the pecans first by spreading them on a baking sheet and baking at 350°F for 5-7 minutes until fragrant. This step makes a noticeable difference in texture and flavor. The flour helps bind the topping so it stays crispy.

Bake the assembled casserole at 375°F for 30-35 minutes until the top is deep golden brown and the edges are bubbling. The coconut milk will create a glossy sheen on top—this is your signal it's done.

I know it seems like too much time, but trust me—this ensures the topping gets properly crispy while the filling remains creamy. Let it rest for 10 minutes before serving to allow the juices to set. The contrast between the creamy filling and crispy topping is what makes this version special.

Pro cooking tips for this dish

Roasting for Sweetness

Skip boiling your sweet potatoes—roasting at 375°F for 25-30 minutes concentrates their natural sugars and creates caramelized edges. Toss them with 2 tbsp coconut oil and 2 tsp cinnamon before roasting for maximum flavor infusion. I use a baking sheet lined with parchment paper for easy cleanup. 🌟

Coconut Milk Magic

Full-fat coconut milk is your secret weapon for creaminess without dairy. Stir it into the mashed sweet potatoes while still warm to ensure smooth emulsification. For an extra-luxurious texture, whisk in 0.5 cup vegan butter until fully melted. The coconut adds subtle tropical notes that complement the sweet potatoes beautifully.

Swirl Perfection

Divide your sweet potato mixture in half—one portion gets 0.25 cup maple syrup for that signature marbled effect. Use a spoon to create a circular pattern in the baking dish, then gently swirl with a knife.

The contrast between the light and dark layers makes this casserole visually stunning. Don't overmix, or you'll lose the pretty patterns!

Crispy Pecan Topping

Toast your pecans first at 350°F for 5-7 minutes to enhance their natural oils and flavor. Mix them with 0.25 cup flour and 1 tbsp brown sugar before sprinkling on top.

The flour acts as a binder, keeping the topping crispy even after baking. Press gently to ensure good contact with the coconut layer.

Baking Time Mastery

Bake at 375°F for 30-35 minutes until the top is deep golden brown. The coconut milk will create a glossy sheen—this is your cue that it's done.

Let it rest for 10 minutes before serving to allow the juices to set. This resting time ensures the perfect creamy texture with a crispy topping.

Make-Ahead Pro Tips

Assemble the casserole (without baking) up to 24 hours ahead—the flavors meld beautifully overnight. For leftovers, store covered in the fridge for up to 5 days or freeze unbaked portions for 3 months.

To reheat, cover with foil and warm at 350°F for 15-20 minutes to maintain crispiness. 💫
