Ingredients for the Best Ruth Chris Copycat Sweet Potato Casserole

Each ingredient in this casserole plays a specific role, working together to mimic that unforgettable restaurant experience.

Milk or Heavy Cream: Adds creaminess and smooth texture to the filling.
Salt: Just a pinch elevates all the other flavors.

How To Make the Best Ruth Chris Copycat Sweet Potato Casserole

Step 1: Cook and Mash the Sweet Potatoes

Peel and boil (or roast) the sweet potatoes until fork-tender. Once cooled slightly, mash them in a large mixing bowl until smooth.

Step 2: Mix the Sweet Potato Filling

Add sugar, eggs, vanilla, melted butter, milk, and a pinch of salt to the mashed sweet potatoes. Use a hand mixer or sturdy whisk to combine until creamy and fully blended.

Step 3: Prepare the Pecan Topping

In a separate bowl, mix together the brown sugar, flour, chopped pecans, and melted butter. Stir until crumbly and evenly coated.

Step 4: Assemble the Casserole

Spread the sweet potato filling into a greased 9×13-inch casserole dish. Even out the surface with a spatula. Sprinkle the pecan topping evenly over the top.

Step 5: Bake to Perfection

Place the casserole in a preheated 350°F (175°C) oven and bake for 30-35 minutes, or until the topping is golden brown and crisp.

Step 6: Cool Slightly and Serve

Allow the casserole to rest for about 10 minutes before serving. This helps the layers set and makes slicing easier.

How to Serve and Store the Best Ruth Chris Copycat Sweet Potato Casserole

This casserole shines brightest when served warm, straight from the oven. It pairs beautifully with holiday mains like glazed ham, roasted turkey, or even grilled chicken. Serve it directly in the baking dish to showcase the gorgeous pecan topping and keep the cozy, rustic vibe. For a more elevated presentation, spoon it into ramekins and garnish with a pecan half on top.

To store leftovers, let the casserole cool completely before covering the dish with foil or transferring it to airtight containers. It will stay fresh in the refrigerator for up to 4 days. To reheat, warm it in a 300°F oven until heated through. You can also microwave individual portions for a quick leftover treat.

This dish also freezes well—just leave off the topping and add it fresh before baking after thawing.

Frequently Asked Questions

Can I make this casserole ahead of time?

Absolutely! You can prepare the sweet potato filling and topping separately, store them in the fridge, and assemble just before baking. It saves you time on busy holidays.

What’s the best way to mash sweet potatoes for a smooth texture?

Use an electric hand mixer for an ultra-smooth texture, or a potato masher for a slightly chunkier, rustic version. Avoid food processors, as they can make the mixture gummy.

Can I substitute canned sweet potatoes?

Yes, but make sure they’re packed in water, not syrup. Drain them well and mash thoroughly before using.

Is it possible to make this dairy-free?

Yes! Use plant-based butter and a non-dairy milk like almond or oat milk. The flavor may vary slightly but will still be delicious.

Can I leave out the pecans?

If you’re nut-free, you can replace pecans with rolled oats or simply make a brown sugar crumb topping without them.

Why is my topping not crunchy?

Your butter might be too soft or the ratio of flour to butter could be off. Make sure the topping is crumbly before baking and that you bake until golden and crisp.
