The texture is silky and light underneath, with a crisp, caramelized topping that brings everything together. If you love a balance of sweet and toasty, this one’s for you.

What Makes This Recipe So Good

• Balanced sweetness: Real maple syrup and brown sugar add warmth without overpowering the sweet potatoes.
• Silky mashed base: Butter, milk, and vanilla create a smooth, custard-like texture.
• Crunchy pecan topping: Buttery, crisp, and lightly spiced, it adds contrast in every bite.
• Make-ahead friendly: Assemble in advance and bake when you’re ready.
• Works for any table: It’s cozy enough for weeknights, yet special enough for holidays.

Ingredients

• For the sweet potato base:
• 3 pounds sweet potatoes (about 4–5 medium), peeled and cubed
• 4 tablespoons unsalted butter, softened
• 1/3 cup pure maple syrup
• 1/4 cup light brown sugar, packed
• 1/3 cup whole milk (or half-and-half for richer texture)
• 2 large eggs, lightly beaten
• 1 teaspoon pure vanilla extract
• 1 teaspoon ground cinnamon
• 1/4 teaspoon ground nutmeg
• 1/2 teaspoon fine sea salt
• For the pecan crumble topping:
• 3/4 cup chopped pecans
• 1/2 cup all-purpose flour
• 1/2 cup light brown sugar, packed
• 1/2 teaspoon ground cinnamon
• 1/4 teaspoon salt
• 5 tablespoons unsalted butter, melted
• 2 tablespoons pure maple syrup
• Optional: Mini marshmallows for a half-and-half topping or a finishing layer

Instructions

1. Heat the oven: Preheat to 350°F (175°C). Grease a 9×13-inch baking dish with butter or nonstick spray.
2. Cook the sweet potatoes: Add peeled, cubed sweet potatoes to a large pot.

   Cover with cold water and add a pinch of salt. Bring to a boil, then simmer 15–20 minutes until very tender.

3. Drain well: Drain the potatoes and return them to the warm pot. Let them sit 2–3 minutes to release extra moisture.
4. Mash the base: Add butter, maple syrup, brown sugar, milk, vanilla, cinnamon, nutmeg, and salt.

   Mash until smooth and creamy. Taste and adjust sweetness or salt as needed.

5. Add the eggs: Once the mixture is warm but not hot, stir in the beaten eggs until fully combined. This helps set the casserole as it bakes.
6. Transfer to the dish: Spread the sweet potato mixture evenly in the prepared baking dish.
7. Make the topping: In a bowl, combine pecans, flour, brown sugar, cinnamon, and salt.

   Stir in melted butter and maple syrup until crumbles form.

8. Top the casserole: Sprinkle the pecan crumble evenly over the sweet potatoes. For a half-and-half look, leave one section uncovered if you plan to add marshmallows later.
9. Bake: Bake for 28–35 minutes, until the topping is golden and the edges are slightly puffed. If adding marshmallows, pull the dish out at 25 minutes, scatter them over the uncovered section, and bake 5–8 more minutes until lightly toasted.
10. Rest and serve: Let the casserole rest for 10 minutes before serving.

    This helps it set and makes cleaner scoops.

How to Store

• Refrigerate: Cool completely, then cover tightly and refrigerate for up to 4 days.
• Reheat: Warm in a 325°F oven, covered with foil, for 15–25 minutes. Uncover for the last few minutes to crisp the topping.
• Freeze: Assemble without baking, wrap well, and freeze up to 2 months. Thaw overnight in the fridge and bake as directed, adding 5–10 extra minutes.
• Make-ahead: Assemble the day before, refrigerate, and bake right before serving.

Health Benefits

• Rich in vitamins: Sweet potatoes are loaded with beta-carotene (vitamin A), which supports eye and immune health.
• Fiber and minerals: They provide fiber, potassium, and manganese, which support digestion and heart health.
• Natural sweetness: Maple syrup and the potatoes themselves allow for less refined sugar overall.
• Healthy fats option: You can swap some butter for olive oil or use milk alternatives to lighten the dish while keeping it creamy.

What Not to Do

• Don’t skip draining time: Waterlogged sweet potatoes can make the casserole runny.
• Don’t add eggs to hot potatoes: If the mixture is steaming hot, the eggs can curdle.

  Let it cool slightly first.

• Don’t overmix the topping: You want loose, chunky crumbles—not a dough.
• Don’t crank up the heat: Baking too hot can burn the topping before the center sets.
• Don’t forget salt: A bit of salt sharpens the sweetness and makes the flavors pop.

Variations You Can Try

• Bourbon maple: Add 1–2 tablespoons bourbon to the sweet potato mixture for a deeper, cozy flavor.
• Orange zest: Stir in 1 teaspoon fresh orange zest and a splash of orange juice for a bright twist.
• Spiced pecan: Add a pinch of cloves or allspice to the topping for holiday spice.
• Gluten-free: Use a 1:1 gluten-free flour in the topping or swap flour for finely ground oats.
• Dairy-free: Use coconut milk or almond milk and plant-based butter. The maple pairs beautifully with coconut.
• Nut-free: Skip pecans and use a brown sugar oat crumble instead. Toasted pumpkin seeds can add crunch.
• Extra protein: Whisk in 1/2 cup plain Greek yogurt to the base for a tangy, creamy lift.

FAQ

Can I use canned sweet potatoes?

Yes, but choose unsweetened canned sweet potatoes or yams, drain well, and reduce added sugar slightly.

You’ll need about 6 cups mashed.

What’s the difference between yams and sweet potatoes?

In most U.S. grocery stores, “yams” are actually orange-fleshed sweet potatoes. True yams are a different root, rarely sold in mainstream markets. For this recipe, the typical orange sweet potato is perfect.

Can I make it without eggs?

You can.

The casserole will be softer but still delicious. Replace eggs with 2 tablespoons cornstarch mixed into the milk, or use a flax “egg” (1 tablespoon ground flaxseed + 3 tablespoons water per egg, rested 5 minutes).

How do I keep the topping crunchy?

Bake uncovered and avoid overloading the filling with liquid. If reheating, uncover for the last few minutes to re-crisp.

Adding a touch of maple to the topping helps it caramelize.

Is this very sweet?

It’s gently sweet, not dessert-like. If you prefer a less sweet version, reduce the brown sugar in the base to 2 tablespoons and keep the maple as-is.

Can I prep parts ahead?

Absolutely. Make the mashed base and refrigerate up to 2 days.

Mix the dry topping separately and store in a container. Combine with butter and maple just before baking.

Final Thoughts

Southern Maple Sweet Potato Casserole is comfort food with a little finesse. The creamy, maple-kissed base and crisp pecan topping make it feel special without being fussy.
