This Ruth’s Chris Sweet Potato Casserole is everything you love about the classic steakhouse side—silky smooth sweet potatoes, just the right amount of sweetness, and that signature brown sugar–pecan topping that bakes up golden, crisp, and irresistible. It’s rich, creamy, and so delicious it practically steals the show on any holiday table.
Why this recipe is so delicious: roasting the sweet potatoes deepens their natural caramelized flavor, a hand mixer whips them into the silkiest texture, and toasted pecans add restaurant-level nuttiness. The topping melts and crisps beautifully without overbaking, and the balance of sweetness + salt is spot-on. It’s shockingly close to the real thing—maybe even better.
If you’re planning your holiday menu, this casserole pairs beautifully with my Crockpot turkey breast, roasted turkey, or either of my cozy pork favorites—pork tenderloin with caramelized pears or grilled pork tenderloin.
Here’s a quick look at how to assemble this cozy sweet potato casserole
✨ Before You Begin
✨ Roast the sweet potatoes, don’t boil. Roasting concentrates flavor, improves texture, and prevents watery filling.
✨ Use a hand mixer. This gives you that signature silky, fluffy restaurant consistency.
✨ Toast the pecans. A quick 5–7 minutes truly elevates the topping.
✨ Cool the potatoes before adding eggs. Warm is fine—hot will scramble them.
✨ Check the casserole early. The topping caramelizes fast; start checking around 28 minutes.
Ruth’s Chris Sweet Potato Casserole Ingredients + Key Notes
This is just a quick glance at what you’ll need. For exact measurements and the full ingredient list, head down to the recipe card below.
- Sweet Potatoes: Use 2 to 2½ pounds whole sweet potatoes to yield the correct 4 cups of mashed flesh. Roasting gives the best texture and flavor.
- Sugar: Granulated sugar sweetens the filling (just like the restaurant). Light brown sugar sweetens the topping and helps it caramelize.
- Eggs: Let the filling cool to “warm” before adding so the eggs incorporate smoothly without scrambling.
- Pecans: Toasting them first makes the topping taste richer and more pronounced—totally worth the extra step.
- Butter: Melted butter in both the filling and topping gives richness and helps everything bake up beautifully.
Sweet Potato Science
When sweet potatoes roast, their natural starches break down into maltose—an exceptionally sweet, caramel-like sugar. This is why roasted sweet potatoes taste deeper and richer than boiled ones. Roasting also drives off excess moisture, letting the casserole set properly without becoming loose or watery.
That perfect silky texture? It comes from whipping the cooked potatoes with a hand mixer, which incorporates tiny air bubbles and gives the filling a light, almost soufflé-like quality.
⭐ Pro Tips
⭐ Whip it longer than you think. One to two full minutes with a hand mixer makes the filling unbelievably smooth and airy. It’s the biggest “wow” upgrade.
⭐ Don’t skip the pecan toasting. It intensifies the nutty flavor and keeps the topping crisp instead of soft.
⭐ Let the topping fully cover the surface. Bare spots can lead to uneven browning.
⭐ Start checking at 28 minutes. Brown sugar caramelizes fast—your goal is golden, not dark brown.
⭐ Make ahead for holidays. Prep each component separately, refrigerate, assemble on the day of, and bake fresh.

Ruth’s Chris Sweet Potato Casserole
Ingredients
- 4 cups sweet potatoes baked and mashed (skins removed)
- 3 tablespoons olive oil
- 1 1/2 cups granulated sugar
- 1 1/4 teaspoons fine salt divided
- 1/2 teaspoon vanilla extract
- 2 large eggs room temperature
- 1/2 cup unsalted butter melted
Pecan Topping
- 1 1/2 cups light brown sugar packed
- 1/2 cup all-purpose flour
- 1 1/2 cups chopped pecans
- 1/2 cup unsalted butter melted
Instructions
Roast the Sweet Potatoes
- Preheat oven to 400°F (204ºC). Line a large baking sheet with parchment paper.
- Slice whole sweet potatoes in half lengthwise. Rub the cut surfaces with olive oil (3 tablespoons).
- Place sweet potatoes cut-side up on the baking sheet and sprinkle evenly with 1/2 teaspoon salt.
- Roast for 40 minutes, or until very tender and easily pierced with a fork (internal temp should be 205–212°F for ideal mashed texture).
- Remove from oven and reduce oven temperature to 350°F (177ºC) for baking the casserole.
- Let sweet potatoes cool until warm but not hot. Scoop flesh into a large mixing bowl; discard skins.
Mix the Sweet Potato Base
- Add the remaining 3/4 teaspoon salt, vanilla (1/2 teaspoon), melted butter (1/2 cup), and sugar (1 1/2 cups) to the bowl.
- Mix with a hand mixer on medium speed for 1–2 minutes, until very smooth, fluffy, and completely combined.
- This yields the classic silky restaurant texture.
- Add eggs (2) once the mixture is no hotter than warm to the touch (hot sweet potatoes can scramble them).
- Mix again on low for 15–20 seconds, just until incorporated.
- Transfer mixture to a lightly greased 9×13-inch casserole dish and spread evenly.
Make the Pecan Topping
- Spread chopped pecans (1 1/2 cups) on a baking sheet and toast at 350°F (177ºC) for 5–7 minutes, just until fragrant. Let cool slightly.
- In a separate bowl, stir together brown sugar (1 1/2 cups), flour (1/2 cup), toasted pecans, and melted butter (1/2 cup) until well combined.
- Sprinkle the topping evenly over the sweet potato layer.
Bake
- Bake at 350°F (177ºC) for 28–35 minutes, or until the topping is golden brown and edges are bubbling around the sides.
- Let the casserole rest 10 minutes before serving.
