Copycat Ruth’s Chris Sweet Potato Casserole (Better Than the Original)

Ruth’s Chris is known for its steaks, but the sweet potato casserole is the side many guests talk about after the meal. It is a rich, spoonable bake: a smooth, lightly sweetened sweet potato base topped with a crisp, buttery brown sugar and pecan crust. It sits somewhere between a side dish and a dessert, which is exactly why people order it for the table.

This homemade copycat approximation gets you the same layered contrast using pantry staples and a few sweet potatoes. You can make the whole dish in one baking dish, serve it alongside a steak dinner, and have enough for seconds without a reservation.

About Ruth’s Chris’s Sweet Potato Casserole

The defining feature of this dish is the contrast between the two layers. The bottom is a creamy, custardlike sweet potato mash enriched with butter, eggs and a little milk, sweetened gently so the potato flavor still comes through. The top is a thick streusel-style crust made from brown sugar, flour, butter and chopped pecans that bakes into a crunchy, caramelized lid.

The technique matters more than the ingredient list. Boil the sweet potatoes until fully tender and drain them very well so the filling is not watery, then mash or whip until smooth. Work the cold butter into the crust mixture until it looks like coarse crumbs, scatter it evenly, and bake until the top is deep golden and the edges bubble.

How Much Does It Cost to Make Ruth’s Chris’s Sweet Potato Casserole at Home?

A full batch makes 8 servings for an estimated $9.48 in ingredients, roughly $1.18 per serving. Ordering the equivalent at Ruth’s Chris runs around $13.00 (approximate menu price), so making it yourself saves an estimated $11.82 (91%). The grocery figures are estimates based on US average grocery prices (US BLS Average Price Data, May 2026) and typical store prices for the rest; the per-ingredient breakdown is in the table above. Your local store and restaurant prices will differ, but the gap stays large because you buy staple ingredients instead of a prepared, served dish, and one batch stretches across several servings.

Why Make It at Home?

Making it at home gives you a full baking dish for a fraction of what a single restaurant side would cost, and you control the sweetness, the nut level and how crisp the crust gets. It also travels well to holiday tables and potlucks, and it can be assembled ahead of time and baked just before serving.

Ingredients for Copycat Ruth’s Chris Sweet Potato Casserole

Here’s the full ingredients list you’ll need to make Ruth’s Chris Sweet Potato Casserole at home:

• 3 lb sweet potatoes, peeled and cubed
• 0.5 cup granulated sugar
• 2 each large eggs, beaten
• 0.5 cup whole milk
• 1 stick unsalted butter, melted, for the filling
• 1.5 tsp vanilla extract, plus a pinch of salt
• 0.5 cup all-purpose flour, for the crust
• 1 cup packed brown sugar, for the crust
• 1 cup chopped pecans, for the crust
• 0.5 stick unsalted butter, cold, for the crust

A few ingredient notes:

• Use orange-fleshed sweet potatoes such as Beauregard or Garnet. They mash smooth and give the deep color and moisture this casserole needs.
• Toast the pecans in a dry skillet for a few minutes before chopping. It deepens the flavor and keeps the crust from tasting flat.
• Use cold butter in the crust so it forms crumbs and bakes up crisp, and melted butter in the filling so it blends evenly.

How to Make Ruth’s Chris Sweet Potato Casserole at Home

Prep: 25 min · Cook: 60 min · Makes: 8 servings

1. Heat the oven to 350°F and butter a 9×13-inch or 2-quart baking dish.
2. Place the cubed sweet potatoes in a large pot, cover with cold water, and boil for 15 to 20 minutes until completely tender when pierced with a fork.
3. Drain the potatoes thoroughly and let them steam dry in the colander for a couple of minutes, then return them to the pot.
4. Mash the potatoes with the melted butter until mostly smooth. Beat in the granulated sugar, eggs, milk, vanilla and a pinch of salt until creamy and well combined.
5. Spread the filling evenly in the prepared baking dish.
6. In a bowl, stir together the brown sugar, flour and chopped pecans, then cut in the cold butter with a fork or your fingertips until the mixture forms coarse crumbs.
7. Sprinkle the crust mixture evenly over the filling, covering it all the way to the edges.
8. Bake for 30 to 35 minutes until the topping is golden and crisp and the filling is set. Rest for 10 minutes before serving.

Tips for the Best Results

• Drain and dry the boiled potatoes well. Excess water is the main cause of a loose, soupy filling.
• Use a hand mixer or food processor for an extra smooth, silky base.
• Spread the topping all the way to the edges so every serving gets crunch.
• Rest the casserole for 10 minutes after baking so the filling sets and slices cleanly.

Common Mistakes to Avoid

• Undercooking the sweet potatoes, which leaves lumps and a firm texture in the filling.
• Skipping the draining step, which makes the casserole watery.
• Using melted butter in the crust, which turns it greasy instead of crumbly.
• Overbaking until the topping burns, since the high sugar content browns quickly.

Variations to Try

• Swap half the pecans for walnuts, or leave the nuts out for a nut-free version with extra oat or flour crumble.
• Add a pinch of cinnamon and nutmeg to the filling for a warmer, holiday-style flavor.
• Bake in individual ramekins for single-serve portions and a higher ratio of crust.

Storage & Reheating

Cool the casserole completely, cover tightly, and refrigerate for up to four days. Reheat individual portions in a 350°F oven or toaster oven until warmed through, which keeps the topping crisp better than a microwave. You can also assemble it up to a day ahead without baking, refrigerate it, and add 10 extra minutes to the bake time.

What to Serve It With

Serve it alongside a seared steak, roast chicken or pork chops, where its sweetness balances savory, salty meat. Simple sides such as green beans, a crisp salad or creamed spinach round out the plate. It also works as a holiday side next to turkey or ham.

Frequently Asked Questions

What does Ruth’s Chris sweet potato casserole taste like?

It tastes like a rich, mildly sweet sweet potato mash topped with a crunchy brown sugar and pecan crust. It lands between a side and a dessert, with buttery, caramelized notes and a soft, creamy center.

Can I use canned sweet potatoes?

Yes. Drain canned sweet potatoes very well and mash them, then reduce the milk slightly because they hold more moisture. Fresh potatoes give a fuller flavor and better texture, but canned works in a pinch.

Can I make this casserole ahead of time?

Yes. Assemble it completely, cover, and refrigerate for up to a day, then bake it a little longer than the original time. You can also bake it fully and reheat portions when needed.

Is this the official Ruth’s Chris recipe?

No. This is a homemade copycat approximation based on the dish’s well-known layers of sweet potato filling and a brown sugar pecan topping. The restaurant’s exact recipe is not public.

Can I freeze sweet potato casserole?

You can freeze it before or after baking. Wrap it tightly and freeze for up to two months, thaw overnight in the refrigerator, and bake or reheat until hot in the center and the topping is crisp.

How do I keep the topping from getting soggy?

Use cold butter, spread the crumbs evenly, and avoid covering the dish while it bakes. When reheating, use the oven rather than a microwave so the crust stays crisp.
