Add Marshmallows: For a gooey topping, sprinkle 1 cup of mini marshmallows over the casserole during the last 5 minutes of baking, then cook until golden brown.
Swap the Nuts: If you’re not a fan of pecans, try walnuts or almonds instead. You can also leave the nuts out entirely!
Add Some Spice: For a little extra warmth and flavor, mix a pinch of cinnamon or pumpkin pie spice into the sweet potatoes.
Use Canned Sweet Potatoes: If you’re short on time, drain and mash canned sweet potatoes, then measure out 3 cups.

How to Make Ruth’s Chris Sweet Potato Casserole

My favorite part of Thanksgiving is always the sides! Serve this sweet potato casserole with my roasted turkey, stuffing, and cranberry sauce. It’s a holiday meal everyone will love!

Prep: First, preheat the oven to 350°F. Then spray a 1½–2-quart casserole dish with cooking spray and set aside.
Make the Filling: In a large bowl, combine the mashed sweet potatoes, brown sugar, eggs, vanilla, milk, and melted butter. Then spread the mixture evenly in the prepared baking dish.
Make the Topping: In a separate bowl, mix the brown sugar, flour, melted butter, and chopped pecans until combined. Sprinkle the topping evenly over the sweet potatoes.
Bake: Bake for 30–40 minutes, until the casserole is set and the topping is lightly browned.

How to Prepare Sweet Potatoes for Casserole

You’ll need cooked, mashed sweet potatoes before making the casserole. Here are four ways to prepare them!

Roast: Pierce the sweet potatoes with a fork and bake at 400°F for about 1 hour, until tender. Cool, peel, and mash.
Boil: Peel and cut into 1-inch pieces. Boil for 20–30 minutes until tender, then drain and mash.
Microwave: Pierce with a fork and microwave for about 15 minutes, or until fork-tender. Cooking time varies depending on size.
Instant Pot: Place pierced, unpeeled sweet potatoes on a trivet with 1 cup of water. Pressure cook on HIGH for 15 minutes (10 for smaller potatoes). Quick release, peel, and mash.

Alyssa’s Pro Tip

Make It Extra Creamy! Use a food processor for a smooth, creamy sweet potato filling, just like you’d expect from a steakhouse! If you prefer a little more texture, a fork or potato masher works great, too.
