The first time I made this, I was honestly intimidated by the Ruth Chris name attached to it. Would it require fancy equipment or some secret technique I didn’t know about?
Turns out, no. The recipe is actually straightforward, and the magic comes from quality ingredients and a bit of patience in layering flavors. I roasted fresh sweet potatoes, whipped them smooth with butter and cream, and watched my kitchen fill with the most incredible aroma.

Ingredients for Ruth Chris Sweet Potato Casserole
- 3 pounds fresh sweet potatoes, peeled and cubed
- 6 tablespoons unsalted butter, divided
- 1/2 cup heavy cream
- 1/4 cup whole milk
- 1 teaspoon vanilla extract
- 1/2 teaspoon cinnamon
- 1/4 teaspoon nutmeg
- 1/4 teaspoon salt
- 1/4 teaspoon black pepper
- 3 tablespoons brown sugar
- 1 cup pecan pieces
- 2 tablespoons maple syrup
Ingredient Notes and Substitutions
- Fresh sweet potatoes: They provide natural sweetness and a creamy texture when roasted and mashed. You can substitute with canned sweet potato puree in a pinch, but reduce the cream slightly since canned versions are already moist.
- Heavy cream: This creates the luxurious, velvety mouthfeel that defines Ruth Chris’s version. Half-and-half works if you prefer less richness, though the texture won’t be quite as silky.
- Unsalted butter: It lets you control the salt level and prevents the dish from tasting overly salty. Salted butter is fine, just reduce the salt in the recipe by half.
- Pecans: They add crunch and nutty flavor to the topping. Walnuts or almonds can substitute, though they’ll taste slightly different and less traditional.
- Vanilla extract: It adds depth and a subtle floral note without making the dish taste vanilla-forward. Almond extract creates a different flavor profile and works well if you prefer that direction.
How to Make Ruth Chris Sweet Potato Casserole
Step 1: Prepare and Roast Your Sweet Potatoes
Preheat your oven to 400 degrees Fahrenheit. Peel your sweet potatoes with a vegetable peeler or sharp knife, then cut them into 1-inch cubes so they cook evenly and quickly.
Spread the cubes on a baking sheet, drizzle lightly with a touch of butter or oil, and roast for 25 to 30 minutes until very tender. You should be able to mash them easily with a fork.
Step 2: Mash the Sweet Potatoes
Transfer the hot roasted sweet potatoes to your large mixing bowl. Use an electric mixer on medium speed to break them down until mostly smooth, about 2 to 3 minutes.
Don’t overwork them; a few small lumps add pleasant texture. Overmixing can make the potatoes gluey and dense.
Step 3: Add the Dairy and Butter
Cut 4 tablespoons of the butter into small pieces and add it to the sweet potatoes while they’re still hot. The residual warmth helps melt the butter evenly.
Pour in the heavy cream and whole milk, then mix on medium speed until the mixture is creamy and smooth. This takes about 1 to 2 minutes.
Step 4: Season the Base
Add vanilla extract, cinnamon, nutmeg, salt, and black pepper to the sweet potato mixture. Stir everything together gently with a wooden spoon until the spices are fully incorporated.
Taste a small spoonful and adjust the seasonings if needed. The mixture should taste lightly sweet with warm spice notes, not overpowering.
Step 5: Prepare the Pecan Topping
In a medium mixing bowl, combine the pecan pieces, brown sugar, and the remaining 2 tablespoons of butter, softened. Stir together until the mixture resembles coarse breadcrumbs.
Drizzle in the maple syrup and toss until everything is moistened and clumpy. This topping adds sweetness, richness, and that signature crunch.
Step 6: Layer the Casserole
Butter or lightly spray your 9×13 inch baking dish. Pour the sweet potato mixture into the dish and spread it into an even layer using a spatula or the back of a spoon.
Smooth the top so it’s level; this helps the casserole cook evenly and look polished when you serve it.
Step 7: Top with Pecans
Spread the pecan mixture evenly over the sweet potato base in a thin, even layer. You want topping in every bite, not clumped in one corner.
Press the topping gently so it adheres to the sweet potatoes. This prevents it from sliding around during baking.
Step 8: Bake Until Golden
Lower the oven temperature to 350 degrees Fahrenheit and bake the casserole for 20 to 25 minutes until the pecan topping is golden brown and the edges of the sweet potato mixture look slightly set.
The center should jiggle very slightly when you shake the dish; it continues cooking slightly after you remove it from the oven. The carry-over heat ensures a creamy center, not a dry, overcooked mess.
Step 9: Cool and Serve
Remove the casserole from the oven and let it rest for 5 minutes. This cooling time lets the creamy base set just enough to hold its shape when you scoop it.
Serve warm directly from the dish, or transfer portions to individual plates. The casserole is best enjoyed within 30 minutes of baking when the pecan topping is crispiest.
Pro Tip: If you’re making this ahead, assemble it completely the night before, cover it with plastic wrap, and refrigerate. Add 5 to 10 minutes to the baking time since you’re starting from cold, and bake at 350 degrees until the top is golden.
Tips for the Best Ruth Chris Sweet Potato Casserole
- Use fresh sweet potatoes instead of canned when possible. They taste more vibrant and give you better control over the texture of the final dish.
- Don’t skip the roasting step for fresh potatoes. Roasting concentrates their natural sugars and deepens the flavor compared to boiling.
- Keep your ingredients close to room temperature before mixing. Cold cream and cold butter incorporate less smoothly and create lumpy spots in the base.
- Taste as you season. Sweet potatoes can vary in natural sweetness, so you may want slightly more or less cinnamon and nutmeg depending on your batch.
- Make the pecan topping while the sweet potatoes are still roasting. This saves time and ensures the topping stays fresh and crunchy.
- Cover the casserole with foil if the topping browns too quickly. Remove the foil for the final 5 minutes so it crisps up.
Common Mistakes to Avoid
- Using canned sweet potato pie filling instead of actual sweet potato puree. Pie filling has added spices and sugar that throw off the flavor balance.
- Overmixing the sweet potatoes once you add the cream. This releases starch and creates a gluey, gummy texture instead of fluffy and creamy.
- Skipping the cooling time before serving. Hot casserole falls apart when you scoop it; a few minutes of rest makes all the difference.
- Baking at too high a temperature. Temperatures above 350 degrees can cause the edges to dry out while the center stays cold.
- Adding marshmallows if you want true Ruth Chris flavor. This restaurant version focuses on pecans and spiced sweetness, not marshmallow.
Serving Suggestions
This casserole shines alongside savory mains that balance its sweetness. It’s the perfect companion to turkey, ham, chicken, or even beef.
- Serve alongside herb-roasted turkey for the ultimate holiday plate
- Pair with honey-glazed ham and cornbread dressing
- Offer as a side with herb-brined roasted chicken
- Combine with roasted Brussels sprouts and gravy for a balanced Thanksgiving spread
- Top with a dollop of whipped cinnamon cream for an extra luxe touch
Variations to Try
- Bourbon Sweet Potato Casserole: Add 2 tablespoons of bourbon to the sweet potato mixture for a deeper, slightly boozy flavor that appeals to grown-up palates. The alcohol cooks off, leaving just the rich taste.
- Marshmallow and Pecan Hybrid: Spread mini marshmallows over half the casserole and pecans over the other half so everyone gets to choose their preferred topping.
- Brown Butter Version: Brown your butter before adding it to the sweet potatoes for a nutty, caramelized depth that elevates the whole dish.
- Candied Pecan Topping: Toss the pecans with a bit more brown sugar and a pinch of cayenne before topping for sweet heat and extra crunch.
- Ginger and Orange Twist: Add 1/2 teaspoon of ground ginger and the zest of one orange to the sweet potato base for bright, warming notes.
Dietary Adaptations
- Gluten-Free: This recipe is naturally gluten-free as written. Just verify that your vanilla extract and spices are certified gluten-free if you’re feeding someone with celiac disease.
- Dairy-Free: Replace heavy cream with coconut cream and use dairy-free butter. The texture changes slightly and becomes less rich, but the flavor remains delicious and warming.
- Vegan: Swap the dairy butter for vegan butter and the cream for full-fat coconut milk. The result tastes less luxurious but still satisfying and flavorful.
- Low-Carb/Keto: This casserole is high in carbs from the sweet potatoes, making it unsuitable for strict keto without major substitutions that change the dish entirely.
Storage and Reheating
Refrigerator
Store leftover casserole in an airtight container for up to 3 days. The pecan topping stays crispy longer if you keep it in a separate container and add it just before serving.
- Cover tightly with plastic wrap to prevent the casserole from absorbing fridge odors
- Store the pecan topping separately in an airtight container
- Reheat individual portions in the microwave for 60 to 90 seconds
Freezer
You can freeze the assembled casserole, unbaked, for up to 1 month. Thaw it in the refrigerator overnight before baking as directed, adding 5 to 10 minutes to the bake time.
- Don’t freeze the assembled casserole with the pecan topping already on
- Wrap the assembled dish tightly in plastic wrap and then foil
- Label with the date so you remember when you made it
Reheating
Reheat the entire casserole covered with foil at 325 degrees for 15 to 20 minutes until warmed through. Add the pecan topping fresh from storage for the crispiest texture, or reheat it in a dry skillet over medium heat for 2 to 3 minutes.
- Reheat slowly to avoid drying out the sweet potato base
- Add a splash of cream if the casserole seems dry after storage
- Microwave individual portions for faster reheating on weeknights

Frequently Asked Questions
Can I Make This Casserole Ahead of Time?
Absolutely, and it’s one of the best features of this recipe. Prepare it completely through Step 7, cover it tightly, and refrigerate for up to 24 hours. Bake it straight from the fridge, adding 5 to 10 extra minutes to the bake time.
What’s the Difference Between This and Regular Candied Yams?
Ruth Chris uses a creamy, buttery base sweetened with the natural sugars in the potatoes rather than piling on marshmallows and brown sugar. The result feels more sophisticated and less like a dessert masquerading as a side dish.
Can I Use Yams Instead of Sweet Potatoes?
True yams are starchy and less sweet than sweet potatoes, so they’ll change the flavor profile. If you use them, add an extra tablespoon of brown sugar and a splash of honey to compensate for the loss of natural sweetness.
Why Is My Casserole Watery After Baking?
This usually happens if you added too much cream or if the sweet potatoes released excess liquid during cooking. Try using less cream next time, or drain any excess liquid from the roasted sweet potatoes before mashing.
How Do I Keep the Pecan Topping from Getting Soggy?
Store the pecan mixture separately from the sweet potato base until you’re ready to bake. If you’ve already assembled it, remove the foil cover for the final 5 to 10 minutes of baking to let the topping dry out and crisp up.
Is This Recipe Actually From Ruth Chris Steakhouse?
This is a beloved copycat recipe that captures the essence of what Ruth Chris serves, though the exact restaurant recipe remains their secret. Many versions exist online, and this one delivers that restaurant luxury to your home kitchen.
