Why This Ruth Chris Sweet Potato Casserole Recipe Works
✔ Restaurant-inspired flavor: Creamy sweet potatoes and a buttery pecan topping recreate the famous Ruth’s Chris side dish at home.
✔ Perfect texture contrast: The smooth filling and crunchy topping make every bite irresistible.
✔ Make-ahead friendly: Perfect for Thanksgiving, Christmas, and holiday entertaining.
✔ A proven crowd-pleaser: This casserole always disappears fast at family gatherings and potlucks.
✨ Before You Begin
✨ Cook the sweet potatoes until very tender: Whether you boil or bake them, the sweet potatoes should mash easily with no firm pieces remaining. This creates the smooth, creamy texture Ruth’s Chris is known for.
✨ Don’t overmix the filling: Mash and mix until smooth, but avoid overworking the sweet potatoes, which can make the filling gummy instead of light and fluffy.
✨ Use fresh pecans: Fresh pecans provide the best flavor and crunch. If your pecans have been sitting in the pantry for a while, give them a quick taste before using.
✨ Prepare the topping separately: Mixing the pecan topping in a separate bowl helps ensure the butter is evenly distributed and creates that signature crumbly texture.
✨ Make it ahead if needed: This casserole is perfect for holiday entertaining because you can assemble it a day in advance and bake it just before serving.
✨ Watch the topping toward the end of baking: The brown sugar and pecans can brown quickly. If the topping is getting darker than you’d like, loosely tent the casserole with foil for the remaining bake time.
Ingredients + Key Notes
Sweet Potatoes: Sweet potatoes are the star of the show, creating the rich, creamy base that makes this casserole so memorable. Choose medium to large sweet potatoes that feel firm and heavy for their size.
Granulated Sugar: Sugar sweetens the filling and enhances the natural flavor of the sweet potatoes without making the casserole overly dessert-like.
Salt: A little salt balances the sweetness and helps all the flavors shine.
Vanilla Extract: Vanilla adds warmth and depth that gives the filling its signature sweet, comforting flavor.
Eggs: Eggs help bind the filling together and create the light, fluffy texture that sets this casserole apart from a basic mashed sweet potato dish.
Butter: Butter adds richness to both the filling and the topping while helping create that classic Ruth’s Chris flavor.
Brown Sugar: Brown sugar gives the pecan topping its caramel-like sweetness and helps create a crisp, golden crust.
All-Purpose Flour: Flour combines with the butter and brown sugar to create a crumbly topping that bakes up perfectly crisp.
Pecans: Chopped pecans provide the signature crunch that makes this copycat Ruth Chris Sweet Potato Casserole so irresistible.
Optional Variations
Extra Pecans: If you love a crunchy topping, increase the pecans slightly for even more texture.
Mini Marshmallows: While not traditional to the Ruth’s Chris version, a handful of marshmallows can be added during the last few minutes of baking for a more classic holiday sweet potato casserole.
Cinnamon: Add a pinch of cinnamon to the filling for a subtle warm spice flavor.
Orange Zest: A little fresh orange zest brightens the sweet potato filling and adds a festive touch for holiday meals.
🥣 How To Make Ruth Chris Sweet Potato Casserole
Prepare the sweet potatoes: Cook the sweet potatoes until they are fork-tender. Drain well if boiled, then mash until smooth. Allow them to cool slightly before adding the remaining filling ingredients.
Make the sweet potato filling: In a large mixing bowl, combine the mashed sweet potatoes, granulated sugar, salt, vanilla extract, eggs, and melted butter. Mix until smooth and creamy, then spread the mixture evenly into a prepared baking dish.
Prepare the pecan topping: In a separate bowl, stir together the brown sugar, flour, chopped pecans, and melted butter until the mixture resembles coarse crumbs.
Assemble the casserole: Sprinkle the pecan topping evenly over the sweet potato filling, covering the entire surface for that signature Ruth’s Chris-style crust.
Bake until golden: Bake until the filling is heated through and the topping is golden brown and crisp. The casserole should be lightly puffed around the edges and smell rich and buttery.
Rest before serving: Allow the casserole to rest for 10 to 15 minutes before serving. This gives the filling time to set slightly and makes it easier to serve neat portions.
⭐ Pro Tips
⭐ Drain the sweet potatoes well: Excess moisture can make the filling loose and prevent it from achieving that rich, creamy texture. If you boil the sweet potatoes, drain them thoroughly before mashing.
⭐ Mash until smooth: For the closest Ruth’s Chris texture, take the time to mash or whip the sweet potatoes until they’re silky smooth with no large lumps remaining.
⭐ Use room-temperature eggs: Room-temperature eggs blend more easily into the filling and help create a smoother casserole.
⭐ Toast the pecans: For even more flavor, lightly toast the pecans before adding them to the topping mixture.
⭐ Spread the topping evenly: An even layer of topping ensures every serving gets the perfect balance of creamy sweet potatoes and crunchy pecan crust.
⭐ Let it rest before serving: Allowing the casserole to sit for 10 to 15 minutes after baking helps the filling set and makes serving easier.
Troubleshooting Sweet Potato Casserole
⭐ Topping too soft? The casserole may need a few more minutes in the oven. The pecan topping should be golden brown and crisp around the edges.
⭐ Filling too loose? Sweet potatoes can vary quite a bit in size and moisture content. If your filling seems thinner than expected, make sure the sweet potatoes were fully roasted and mash them while they’re still warm so excess moisture can evaporate.
⭐ Topping browning too quickly? Loosely cover the casserole with foil and continue baking until the center is heated through.
⭐ Want extra crunch? Add a few extra chopped pecans to the topping mixture before baking.
Make-Ahead Instructions
One of the reasons this Ruth Chris Sweet Potato Casserole is so popular during the holidays 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 layer, then bake as directed.
For longer prep: The sweet potato filling can be prepared up to 2 days in advance and refrigerated until you’re ready to assemble and bake.
Holiday hosting tip: Preparing the casserole ahead of time frees up valuable oven space and makes Thanksgiving and Christmas dinner much less stressful.
Storing + Reheating + Freezing
How To Store: Cover the casserole tightly or transfer leftovers to an airtight container and refrigerate for up to 4 days. The flavors continue to develop as it sits, making leftovers especially delicious.
How To Reheat: For best results, reheat the casserole in a 325°F oven until warmed through. If you’re reheating a larger portion, cover it loosely with foil to prevent the pecan topping from becoming too dark.
- Individual servings can also be reheated in the microwave in 30-second intervals until hot.
How To Freeze: You can freeze Ruth Chris Sweet Potato Casserole either before or after baking.
Before baking: Assemble the sweet potato filling in a freezer-safe 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: Allow the casserole to cool completely, then wrap tightly and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
Frequently Asked Questions
◆ Can you make Ruth Chris Sweet Potato Casserole ahead of time?
Yes! This casserole is perfect for making ahead. Assemble the sweet potato filling up to 24 hours in advance and refrigerate it. Prepare the pecan topping separately, then add it just before baking for the best texture.
◆ What temperature should sweet potato casserole reach?
Sweet potato casserole is fully heated when the center reaches 165°F. Since the sweet potatoes are already cooked before baking, the main goal is to heat the casserole through and crisp the topping.
◆ Can I freeze sweet potato casserole?
Absolutely. You can freeze it either before or after baking. For the best results, freeze the sweet potato filling separately and add the pecan topping just before baking.
◆ What’s the difference between sweet potato casserole and sweet potato soufflé?
Sweet potato soufflé is typically lighter and fluffier, while sweet potato casserole tends to be denser and topped with a crunchy streusel or pecan topping. The Ruth’s Chris version falls somewhere in between, with a creamy filling and crisp pecan crust.
◆ Can I use canned sweet potatoes?
Fresh sweet potatoes will give you the best flavor and texture, but canned sweet potatoes can work in a pinch. Be sure to drain them well before mashing and mixing the filling.
◆ Why is my topping not crunchy?
The topping may need a few extra minutes in the oven to fully crisp. Make sure the butter is evenly distributed throughout the topping mixture and bake until the pecans are golden brown.

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.
