Healthy Sweet Potato Casserole With Pecans

Many sweet potato casseroles have as much sugar as a dessert, with butter, brown sugar and a full layer of marshmallows on top. This healthy sweet potato casserole with pecans lets the sweet potatoes do most of the work. Roasting them brings out their natural sweetness, so you only need a little maple syrup. On top, a crunchy cinnamon-pecan crumble adds texture and a toasty flavor.

It still feels special enough for Thanksgiving, but it's light enough for an everyday dinner.

Ingredients

Sweet potato filling

• 3½ lb (1.6 kg) sweet potatoes (about 5 medium)
• ¼ cup (60 ml) pure maple syrup
• 1 large egg
• ¼ cup (60 ml) milk (any kind)
• 2 tablespoons melted butter or coconut oil
• 1 teaspoon vanilla extract
• 1 teaspoon ground cinnamon
• ¼ teaspoon ground nutmeg
• ½ teaspoon salt

Pecan topping

• ¾ cup (75 g) chopped pecans
• ⅓ cup (30 g) old-fashioned rolled oats
• 2 tablespoons almond flour (or all-purpose flour)
• 2 tablespoons maple syrup
• 1 tablespoon melted butter or coconut oil
• ½ teaspoon cinnamon
• Pinch of salt

How to Make It

Step 1: Roast the sweet potatoes

1. Preheat the oven to 400°F (200°C). Line a baking sheet with foil (sweet potatoes drip sticky syrup).
2. Scrub the sweet potatoes and poke each one several times with a fork.
3. Roast for 45–60 minutes, until a knife slides in with no resistance.
4. Let them cool for 10 minutes, until you can handle them.

Why roast instead of boil? Roasting makes them sweeter and less watery. Boiled sweet potatoes can make a runny casserole.

Step 2: Make the filling

1. Lower the oven to 350°F (175°C). Grease a 9×9-inch or 2-quart baking dish.
2. Cut the sweet potatoes open and scoop the soft flesh into a large bowl. Throw away the skins. You should have about 4 cups.
3. Mash until smooth (a potato masher or hand mixer works).
4. Mix in the maple syrup, egg, milk, melted butter, vanilla, cinnamon, nutmeg and salt until smooth.
5. Spread evenly in the baking dish.

Step 3: Make the topping

Stir the pecans, oats, almond flour, maple syrup, melted butter, cinnamon and salt together until crumbly and coated. Sprinkle evenly over the sweet potatoes.

Step 4: Bake

Bake for 25–30 minutes, until the filling is set around the edges and the pecan topping is golden and toasty. If the topping browns too fast, cover loosely with foil.

Let it rest for 10 minutes before serving.

Tips

• Pick orange sweet potatoes. Varieties with deep orange flesh (like Garnet or Jewel) are the sweetest and creamiest.
• Taste before adding the egg. Add a bit more maple if your sweet potatoes are less sweet.
• Watch the pecans. Nuts can go from toasted to burnt quickly. Check at 20 minutes.
• For a silky texture, use a hand mixer to whip the sweet potatoes.

Common Problems

The casserole is watery. The sweet potatoes were boiled or very wet. Roast them, or cook the mash in a pan for a few minutes to dry it out.

The topping is soggy. It needs more baking time, or it was covered too long. Uncover for the last 10 minutes.

It's not sweet enough. Drizzle a little extra maple syrup on top before serving.

Variations

• Egg-free: Leave out the egg. The filling will be a little softer.
• Dairy-free: Use coconut oil and plant milk.
• Nut-free: Use pumpkin seeds instead of pecans.
• Small marshmallow touch: Add a handful of mini marshmallows over half of the dish for the kids.
• Orange zest: Add 1 teaspoon orange zest to the filling for a bright holiday flavor.

What to Serve With It

It's a classic side for roast turkey, baked ham, roast chicken or pork chops. It's also good next to green beans and stuffing for a holiday plate. For an easy everyday meal, try it with sliced homemade turkey lunch meat and a green salad.

Make Ahead, Storage and Freezing

Make ahead: Make the filling and topping up to 2 days ahead. Store them separately in the fridge. Add the topping and bake just before serving, adding 5–10 minutes to the baking time.

Fridge: Leftovers keep covered for 3–4 days.

Freezer: Freeze the baked casserole (without topping is best) for up to 3 months. Thaw overnight in the fridge, add fresh topping, and bake at 350°F for 30–35 minutes.

Reheat: Warm portions in the microwave for 1–2 minutes, or in a 350°F oven for 15–20 minutes, until hot.

FAQs

Can I use canned sweet potatoes?

Yes. Use about 4 cups drained canned sweet potatoes (not in syrup). Skip the roasting.

Can I make it without maple syrup?

Use honey or brown sugar instead. Taste first; you may need less.

Is it really healthy?

It has less sugar and fat than many traditional versions, plus fiber from the sweet potatoes and nuts. It's still a holiday side, so enjoy it in normal portions.

Can I microwave the sweet potatoes?

Yes. Microwave pierced sweet potatoes for 8–12 minutes, turning once, until soft. The flavor is a little less sweet than roasted.
