This Ruth’s Chris Sweet Potato Casserole is a copycat of the famous steakhouse side dish that’s become almost as legendary as the restaurant’s steaks. A silky-smooth sweet potato filling is topped with Ruth’s Chris’s signature buttery brown sugar pecan crust, creating the perfect combination of creamy, crunchy, and absolutely irresistible.
Unlike traditional sweet potato casseroles, this version skips the marshmallows in favor of an elegant pecan topping that bakes into a crisp, caramelized crust. The whipped sweet potato filling is rich, velvety, and lightly sweet, making every bite taste just like the restaurant favorite.
Whether you’re recreating your favorite Ruth’s Chris meal at home or serving it alongside Thanksgiving or Christmas dinner, this make-ahead copycat is guaranteed to impress. Pair it with Roasted Turkey, Stuffed Turkey Breast, Crockpot Turkey Breast, or a baked ham finished with my Ham Glaze for a holiday meal worthy of a special occasion.
⭐ What Makes Ruth’s Chris Sweet Potato Casserole Different?
Unlike many traditional sweet potato casseroles, the Ruth’s Chris version skips the marshmallows and lets the sweet potatoes shine. The filling is whipped until incredibly smooth and creamy, creating a light, almost soufflé-like texture that’s richer and more elegant than a rustic mashed sweet potato casserole.
Instead of a marshmallow topping, Ruth’s Chris finishes the casserole with its signature buttery pecan crust. As it bakes, the brown sugar caramelizes while the pecans become toasted and crisp, creating the perfect contrast to the silky filling underneath.
The result is a restaurant-quality side dish that’s sweet enough to feel indulgent yet balanced enough to serve alongside steak, turkey, ham, or any holiday meal.
✨ Before You Begin
✨ Bake the sweet potatoes whenever possible. Baking concentrates their natural sweetness and creates the rich, creamy texture that makes this Ruth’s Chris copycat so special.
✨ Whip the filling until silky smooth. The restaurant version is known for its velvety texture, so don’t be afraid to mix until the sweet potatoes are completely smooth and creamy.
✨ Use fresh pecans. Fresh pecans provide the best flavor and crunch. For even more nutty flavor, toast them for a few minutes before making the topping.
✨ Mix the topping separately. Stirring the pecans, brown sugar, butter, and other topping ingredients together first ensures every bite bakes up buttery, crisp, and evenly coated.
✨ Make it ahead with confidence. Assemble the casserole up to one day in advance, then bake it just before serving for an easy holiday side dish.
✨ Watch the topping during the final bake. Brown sugar and pecans can brown quickly. If the topping is getting darker than you’d like, loosely tent the casserole with foil until the filling is hot and the topping is perfectly crisp.
Ingredients + Key Notes
Sweet Potatoes – Fresh sweet potatoes create the rich, velvety filling that makes this casserole so memorable. Baking them instead of boiling helps concentrate their natural sweetness and keeps the filling thick and creamy.
Granulated Sugar – Sweetens the filling and gives it the signature dessert-like flavor that Ruth’s Chris is famous for without overpowering the sweet potatoes.
Salt – Just enough to balance the sweetness and enhance the buttery flavor throughout the casserole.
Vanilla Extract – One of the signature flavors in the filling. Vanilla adds warmth and depth, giving the casserole its unmistakable steakhouse-style taste.
Eggs – The secret to the casserole’s light, soufflé-like texture. Use room-temperature eggs and beat them lightly before mixing them into the filling for the smoothest results.
Butter – Adds richness to both the filling and the pecan topping while contributing to the luxurious flavor people expect from the Ruth’s Chris version.
For the Signature Pecan Crust
Brown Sugar – Caramelizes as the casserole bakes, creating the sweet, crisp topping that’s one of the restaurant’s defining features.
All-Purpose Flour – Combines with the butter to create a tender, crumbly topping instead of a hard candy-like crust.
Pecans – The hallmark of Ruth’s Chris Sweet Potato Casserole. They add buttery, nutty flavor and the signature crunch that contrasts beautifully with the silky filling.
🥣 How to Make Ruth’s Chris Sweet Potato Casserole
Start by cooking the sweet potatoes until they’re very tender. For the richest flavor, I recommend baking them, but boiling will also work if you drain them well. Mash the sweet potatoes until completely smooth, then let them cool slightly before mixing in the sugar, salt, vanilla, room-temperature eggs, and melted butter. Beat everything together until the filling is light, creamy, and silky, then spread it evenly into a prepared baking dish.
In a separate bowl, stir together the brown sugar, flour, chopped pecans, and melted butter until the mixture forms coarse, buttery crumbs. Sprinkle the topping evenly over the sweet potato filling, making sure every bite will have a little of that signature pecan crust.
Bake until the filling is hot and lightly puffed around the edges and the topping is golden brown and crisp. Let the casserole rest for 10–15 minutes before serving so the filling has time to set and the buttery pecan topping stays perfectly crunchy.
⭐ Pro Tips
⭐ Bake the sweet potatoes for the best flavor. Baking concentrates their natural sweetness and creates the rich, velvety filling that’s the hallmark of Ruth’s Chris Sweet Potato Casserole.
⭐ Whip the filling until completely smooth. A silky filling is one of the signature characteristics of the restaurant version, so don’t stop mixing until it’s creamy and lump-free.
⭐ Toast the pecans before making the topping. Just a few minutes in the oven deepens their flavor and gives the pecan crust an even richer, nuttier taste.
⭐ Spread the topping evenly. An even layer ensures every serving has the perfect balance of creamy sweet potatoes and crisp, buttery pecan topping.
⭐ Let the casserole rest for 10–15 minutes before serving. The filling will set slightly, making it easier to serve while keeping the topping perfectly crisp.
Make-Ahead Instructions
One of the reasons this Ruth’s Chris Sweet Potato Casserole is such a holiday favorite is that it’s incredibly make-ahead friendly.
Prepare up to 24 hours ahead: Assemble the sweet potato filling and spread it into the baking dish. Prepare the pecan topping separately and store it in an airtight container in the refrigerator.
Before baking: Remove the casserole from the refrigerator about 30 minutes before baking. Sprinkle the pecan topping evenly over the sweet potato filling, then bake as directed.
Need even more time? The sweet potato filling can be prepared up to 2 days in advance and refrigerated until you’re ready to add the topping and bake.
Holiday hosting tip: Keeping the topping separate until baking helps it stay crisp and buttery while freeing up valuable prep time on Thanksgiving or Christmas Day.
Storing + Reheating + Freezing
How to Store: Cover the casserole tightly or transfer leftovers to an airtight container. Refrigerate for up to 4 days. The flavors continue to meld as it rests, making leftovers just as delicious the next day.
How to Reheat: For the best texture, reheat the casserole in a 325°F oven until warmed through. If reheating a larger portion, loosely cover it with foil to keep the pecan topping from overbrowning. Individual servings can also be reheated in the microwave in 30-second intervals until hot.
How to Freeze: Ruth’s Chris Sweet Potato Casserole freezes well both before and after baking.
- Before baking: Assemble the sweet potato filling in a freezer-safe baking dish, but leave off the pecan topping. Wrap tightly and freeze for up to 3 months. Thaw overnight in the refrigerator, add the topping, and bake as directed.
- After baking: Let the casserole cool completely, then wrap tightly and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating. Keep in mind that the pecan topping may lose a little of its crispness after freezing, but it will still taste delicious.

Frequently Asked Questions
◆ Is Ruth’s Chris Sweet Potato Casserole served with marshmallows?
No. Unlike many traditional sweet potato casseroles, the Ruth’s Chris version is topped with a buttery brown sugar pecan crust instead of marshmallows. That crisp, caramelized topping is one of the signature features that makes this casserole so famous.
◆ Can you make Ruth’s Chris Sweet Potato Casserole ahead of time?
Yes! This casserole is perfect for holiday entertaining. Prepare the sweet potato filling up to 24 hours in advance and refrigerate it. Make the pecan topping separately, then sprinkle it over the casserole just before baking for the crispiest texture.
◆ What temperature should sweet potato casserole reach?
Because the sweet potatoes are fully cooked before baking, the casserole is done when the center reaches 165°F, the filling is hot and lightly set, and the pecan topping is golden brown and crisp.
◆ What’s the difference between sweet potato casserole and sweet potato soufflé?
Sweet potato soufflé is typically lighter and more airy, while sweet potato casserole is usually denser and topped with a streusel or pecan topping. Ruth’s Chris combines the best of both—a silky, soufflé-like filling with its famous buttery pecan crust.
◆ Can I use canned sweet potatoes?
Yes, but fresh sweet potatoes will give you the closest flavor and texture to the restaurant version. If using canned sweet potatoes, drain them well before mashing so the filling doesn’t become too soft.
◆ Why isn’t my pecan topping crunchy?
The topping may simply need a few more minutes in the oven. It should be deeply golden with toasted pecans and a crisp, buttery texture. If the filling is hot but the topping isn’t crisp enough, continue baking while watching carefully so it doesn’t overbrown.

Ruth 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.

Notes
- 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.
