Martha Stewart Sweet Potatoes Casserole with Pecan Topping Recipe

Martha Stewart sweet potatoes casserole with pecan topping is the holiday side I make when I want something rich but not too sweet — silky, lightly spiced sweet potato mash under a crisp, buttery pecan streusel. The filling is smooth with a few small lumps for texture, and the cinnamon and nutmeg come through without taking over. The topping is the best part: clumpy, nutty, and it stays crunchy. This version is inspired by Martha Stewart’s classic American home cooking, with balanced sweetness and plenty of pecans.

It takes about 100 minutes from start to finish, and most of that is hands-off roasting and baking. The method is straightforward enough for a first-timer, so it works for a weeknight dinner, a holiday table, or a potluck where you want a side that travels well. You can also assemble it ahead and bake it later.

Why This Martha Stewart Sweet Potatoes Casserole with Pecan Topping Works

Roasting the sweet potatoes instead of boiling them is the key move. The oven pulls out extra moisture, so the mash stays creamy and holds its shape on a spoon rather than turning watery. A warm, lightly beaten egg mixture and just enough sugar let the natural sweetness lead.

The topping gets its crunch from melted butter stirred into flour, brown sugar, and cinnamon until it looks like coarse streusel, then folded with chopped pecans. Leaving the surface uneven and skipping the press-down gives you crisp peaks instead of a dense, flat crust.

What You’ll Love About It

You get a smooth, gently spiced base and a buttery pecan topping that actually stays crisp. It feeds eight generously and mostly bakes hands-off. It also travels and reheats well, which makes it a reliable potluck or holiday side.

Ingredients

Here is everything you need, with the base and topping grouped. Use the amounts below exactly.

For the Sweet Potato Base

• 4 pounds (1.8kg) sweet potatoes — scrubbed
• 1/2 cup (113g) unsalted butter — melted and slightly cooled
• 1/2 cup (120ml) whole milk — warmed
• 1/3 cup (67g) granulated sugar
• 2 large eggs — lightly beaten
• 1 teaspoon vanilla extract
• 1 teaspoon kosher salt
• 1/2 teaspoon ground cinnamon
• 1/4 teaspoon ground nutmeg

For the Pecan Topping

• 3/4 cup (94g) all-purpose flour
• 3/4 cup (158g) packed light brown sugar
• 1/2 teaspoon kosher salt
• 1/2 teaspoon ground cinnamon
• 6 tablespoons (85g) unsalted butter — melted
• 1 1/2 cups (170g) pecan halves — roughly chopped

Equipment

• Rimmed baking sheet — lined with parchment for roasting
• 9×13-inch (23x33cm) baking dish — buttered
• Large mixing bowl — for the sweet potato base
• Medium bowl — for the pecan topping
• Potato masher — a fork works too
• Wire rack — for resting the casserole

How to Make Martha Stewart Sweet Potatoes Casserole with Pecan Topping

Step 1: Roast the Sweet Potatoes

Heat the oven to 400°F (200°C). Prick the sweet potatoes all over with a fork and set them on a rimmed baking sheet lined with parchment. Roast until a knife slides in with no resistance, 50 to 60 minutes, then cool until easy to handle. Roasting rather than boiling keeps the mash from turning watery.

Step 2: Mash the Flesh

Reduce the oven to 350°F (175°C) and butter a 9×13-inch (23x33cm) baking dish. Scoop the sweet potato flesh into a large bowl and discard the skins. Mash until mostly smooth, leaving a few small lumps for texture.

Step 3: Mix the Base

Stir the melted butter, warmed milk, granulated sugar, eggs, vanilla, 1 teaspoon salt, cinnamon, and nutmeg into the sweet potatoes until evenly combined. Taste and adjust the salt. The mixture should be creamy but hold its shape on a spoon, not loose and soupy.

Step 4: Spread in the Dish

Spread the sweet potato mixture evenly in the prepared dish with a spatula, smoothing the top. Set it aside while you make the topping so the base can settle.

Step 5: Make the Pecan Topping

In a medium bowl, whisk the flour, brown sugar, 1/2 teaspoon salt, and cinnamon. Pour in the melted butter and stir with a fork until evenly moistened and clumpy, then fold in the pecans. The mixture should look like coarse, nutty streusel with no dry flour pockets.

Step 6: Add the Topping

Scatter the pecan topping in an even layer over the sweet potatoes, covering the surface but leaving some peaks for browning. Don’t press it down, or the topping will bake dense instead of crisp.

Step 7: Bake Until Golden

Bake until the filling is hot through and the topping is deep golden brown and fragrant, 35 to 40 minutes. If the pecans darken too quickly, tent the dish loosely with foil after 25 minutes.

Step 8: Rest Before Serving

Let the casserole rest on a wire rack for 10 minutes before serving so the filling sets and the topping crisps. Serve warm, spooned into portions with plenty of the crunchy pecan topping.

What to Serve With It

This fits right in next to roast turkey or roast chicken, glazed carrots, and a big green salad with a bright vinaigrette. A spoonful of cranberry sauce adds a tart contrast to the sweet topping. Keep the rest of the plate simple so the casserole stays the star.

Tips for the Best Results

• Dry the flesh — Let roasted potatoes steam off for a few minutes before mashing.
• Warm the milk — Cold milk can make the mash seize and look grainy.
• Beat eggs first — Lightly beating them keeps streaks out of the filling.
• Chop evenly — Similar-sized pecans brown at the same rate.
• Watch the nuts — Pecans go from golden to dark in a couple of minutes.
• Rest before scooping — Ten minutes helps portions hold together neatly.

Easy Variations

• Maple finish — Swap 2 tablespoons of the granulated sugar for maple syrup.
• Extra spice — Add 1/4 teaspoon ground ginger to the base for warmth.
• Toasted nuts — Toast the 1 1/2 cups (170g) pecans for 5 minutes first for deeper flavor.
• Individual portions — Bake in eight small ramekins and start checking at 20 minutes.

Storing and Reheating

Cool completely, cover tightly, and refrigerate for up to 3 days. To freeze, assemble without baking, wrap tightly, and freeze for up to 2 months, then thaw overnight in the refrigerator before baking. Reheat covered with foil at 350°F (175°C) for 20 to 25 minutes, uncover for the last 5 minutes, and check it reaches 165°F (74°C) in the center.

FAQs

Can I make this Martha Stewart sweet potatoes casserole with pecan topping recipe ahead of time?

Yes. Make the sweet potato base up to 1 day ahead and refrigerate it in the baking dish. Add the topping just before baking so the streusel stays crisp.

Can I use canned sweet potato puree instead of roasting?

You can substitute about 4 cups (roughly 1kg) of drained, plain canned puree. Skip the roasting step and mix the base directly, adding the warmed milk a splash at a time until it holds its shape.

How do I know when the casserole is done?

The filling should be hot through with no cool center, and the topping deep golden brown and fragrant. If the nuts are browning before the middle is hot, tent the dish with foil.

Why did my topping turn out soft?

Pressing the streusel down or covering the dish during baking traps steam and softens the crumbs. Scatter it loosely, leave some peaks, and only tent with foil if the pecans darken early.
