Ruth’s Chris Sweet Potato Casserole
If you’ve ever had the sweet potato casserole from Ruth’s Chris, you already know why people talk about it.
It’s rich, buttery, perfectly sweet, and that crunchy pecan topping makes it hard to stop at one spoonful.
This is one of those side dishes that somehow steals the show every single time.
It usually starts as “I’ll just have a little,” then somehow you’re back for another scoop before dinner is even over.
The sweet potatoes are whipped until they’re smooth and creamy with butter, brown sugar, and just enough vanilla to make everything taste warm and cozy.
Then comes the best part. A buttery pecan topping that bakes into a golden, crunchy layer while the filling stays soft underneath.
I love making this for Thanksgiving, but honestly, it’s too good to save for one day a year.
It goes with turkey, ham, roast chicken, or pretty much anything you’re serving for a family dinner.
If you’re looking for a copycat that tastes incredibly close to the restaurant version, this is the one.
It has that creamy filling, the crisp pecan topping, and the kind of homemade flavor that keeps everyone coming back for seconds.

How to Make Ruth’s Chris Sweet Potato Casserole
Cook the sweet potatoes
Peel the sweet potatoes and cut them into large chunks so they cook evenly.
Place them in a large pot and cover with cold water.
Bring everything to a boil, then reduce to a gentle simmer and cook for about 15 to 20 minutes, or until the potatoes are completely fork tender.
Drain well.
Return the potatoes to the hot pot for a minute or two to let any excess moisture evaporate. This helps keep the casserole rich and fluffy instead of watery.
Mash the filling
Transfer the hot sweet potatoes to a large mixing bowl.
Add the softened butter while the potatoes are still hot so it melts into them.
Using a potato masher or hand mixer, mash until smooth.
Now add the sugar, eggs, milk, vanilla, cinnamon, nutmeg and salt.
Beat until the mixture is completely creamy and silky with no noticeable lumps.
The filling should be thick but easily spreadable.
Prepare the baking dish
Lightly butter a 9×13-inch baking dish.
Spread the sweet potato mixture evenly into the dish, smoothing the top with a spatula.
Try to create an even layer so the topping browns evenly during baking.
Make the pecan topping
In another bowl, combine the chopped pecans, brown sugar, flour, cinnamon and salt.
Pour over the melted butter.
Mix everything together until the mixture resembles coarse crumbs.
Some larger buttery clumps are perfectly fine—they’ll bake into extra crunchy bites.
Sprinkle the topping evenly across the sweet potato filling.
Don’t press it down.
Keeping it loose helps create the crunchy texture that’s so characteristic of this casserole.
Bake
Bake in a preheated 350°F (175°C) oven for 30 to 35 minutes.
The filling should be hot all the way through, and the topping should be deeply golden with toasted pecans and bubbling butter around the edges.
If you’d like the topping slightly darker, place it under the broiler for one to two minutes, watching carefully so the pecans don’t burn.
Serve
Let the casserole rest for about 10 minutes before serving.
As it cools slightly, the filling firms up just enough while staying creamy underneath.
Scoop generous portions onto each plate, making sure everyone gets plenty of that buttery pecan topping.
Tips for the Best Sweet Potato Casserole
Choose orange-fleshed sweet potatoes for the richest colour and naturally sweet flavour.
Drain the potatoes thoroughly after boiling. Too much water can make the filling loose.
Mash while the potatoes are still hot. They become much smoother and creamier this way.
Don’t overmix after adding the eggs. Mix only until everything is combined.
Leave the topping loose instead of packing it down. That’s what gives it those crisp buttery crumbles shown in the photos.
Toasting the pecans for five minutes before mixing the topping adds even more flavour if you have the extra time.
Easy Variations
Add a pinch of pumpkin pie spice for extra warmth.
Swap half the pecans for chopped walnuts if that’s what you have on hand.
A splash of maple syrup in the filling gives the casserole another layer of sweetness without overpowering the sweet potatoes.
For an even richer version, replace the milk with heavy cream.

Make Ahead
This casserole is perfect for preparing in advance.
Assemble everything except the topping, cover and refrigerate for up to two days.
Prepare the topping separately and refrigerate it as well.
When you’re ready to bake, sprinkle the topping over the casserole and bake as directed.
Storing Leftovers
Cover tightly and refrigerate for up to four days.
The topping will soften slightly in the refrigerator, but the flavour is just as delicious.
Freezing
You can freeze the casserole before or after baking.
Wrap it tightly with plastic wrap and foil, then freeze for up to three months.
Thaw overnight in the refrigerator before baking or reheating.
Reheating
Cover loosely with foil and warm in a 325°F oven for about 20 minutes until heated through.
Remove the foil during the final few minutes so the topping crisps back up.
Individual portions can also be reheated in the microwave.
Frequently Asked Questions
Is this the same sweet potato casserole served at Ruth’s Chris?
It’s a homemade version inspired by the restaurant’s famous recipe. It captures the same creamy filling and buttery pecan topping that people love.
Can I bake the sweet potatoes instead of boiling them?
Yes. Baking actually gives the sweet potatoes an even deeper flavour because it concentrates their natural sweetness. Bake at 400°F until fork tender, then scoop out the flesh.
Can I make it ahead for Thanksgiving?
Absolutely. In fact, it’s one of the easiest holiday side dishes to prepare in advance. Assemble the casserole a day or two ahead and bake just before serving.
Why is my filling watery?
Usually because the sweet potatoes weren’t drained well enough after boiling. Letting them sit in the hot pot for a minute after draining helps remove excess moisture.
Can I use canned sweet potatoes?
Fresh sweet potatoes are highly recommended. They give the casserole a much better texture and flavour than canned varieties.
Do I have to use pecans?
Pecans are traditional and match the photos perfectly, but walnuts can be substituted if needed. The topping will still bake up buttery and crisp.
