Pressure Cooker Ruth’s Chris Sweet Potato Casserole is a decadent, sweet and creamy side dish, which is served at the famous Ruth’s Chris Steak House.
Ruth, a single mom, mortgaged her home and purchased a restaurant called Chris Steak House.
“When a kitchen fire destroyed Chris Steak House in 1976, Ruth was forced to relocate the restaurant to stay in business.
But the Chris Steak House name wasn’t allowed to move with it. So, with little time and a mischievous smile, Ruth added her own name to the sign, making it “Ruth’s Chris Steak House.” And it worked—that tongue-twister of a name was born.”
Ruth’s Chris Sweet Potato Casserole is very rich and delicious. It is served as a side dish at the Ruth’s Chris Steak House.
This Pressure Cooker Ruth’s Chris Sweet Potato Casserole recipe is the original recipe, which I have converted to the Instant Pot, Ninja Foodi or Pressure Cooker. It can also be made in the oven. I will show you each method.
The sweet potatoes quickly cook in the pressure cooker. A Steamer/Strainer Basket and Trivet is all you need.
If you prefer to use your stove, you can boil or steam the sweet potatoes in a sauce pan until soft.

Sweet Potatoes versus Yams
What is carried in the grocery store are mostly likely sweet potatoes. Yams are a bit harder to find in regular grocery stores, so check out an in international grocery store.
Sweet potatoes are root of a vine in the morning glory family. Sweet potatoes can be yellow, purple, brown, white or orange on the outside. The flesh inside can be orange, reddish, white or yellow inside.
Yams are starchier and drier than sweet potatoes and are not as sweet. They look similar to yuca and are very delicious. The skins of the yams are drier and have a bark like skin similar to yuca. Speaking of yuca, if you have not ever tried them, check out my Pressure Cooker Cuban Yuca Con Mojo {Cassava} or Air Fryer Yuca Fries with Creamy Curry Mustard Sauce recipes. Yuca is absolutely delicious.
Ruth’s Chris Sweet Potato Casserole is more like a soufflé, so whipping them well with a Hand Mixer will incorporate air and make them nice and fluffy.
The whipping with the eggs will also cause a nicer rise and a lighter texture to the finished casserole.
Chop up the pecans and add them to a bowl with brown sugar and flour. Mix it together well. Add melted butter and use a fork to combine until crumbly. Use your fingers to break up big clumps. The crust mixture should be crumbly and not drenched with butter.
Making Pressure Cooker Ruth Chris Sweet Potato Casserole in Advance
If you want to make the casserole in advance, keep the topping separate from the sweet potato mixture.
Assemble and cook when you are ready.
Alternatively, just the sweet potato mixture can be cooked in advance and then when almost ready to serve, add the topping and bake.
The crust can be added to the filling and cooked in the pressure cooker, or the filling can be cooked separately and then the crust added and crisped up in the oven, air fryer or using a CrispLid.
When ready to add the crust topping, place the Mealthy CrispLid (buy from Mealthy) / Mealthy CrispLid (buy from Amazon) on top and cook until the topping is nice and crisp.
Both the oven method and Instant Pot, Ninja Foodi or Pressure Cooker method is recommended to bake the filling in advance to help make Thanksgiving and Christmas a little less stressful.
Then just add the Crust, bake and your Ruth’s Chris Sweet Potato Casserole is hot and ready to eat, whether you are hosting Thanksgiving, or you have brought this with you as a guest.
If white sweet potatoes don’t seem festive enough, use the traditional orange colored ones.

My daughter is extremely allergic to nuts, but not to those that are actually seeds, like pistachios, sunflower seeds, pumpkin seeds (pepitas), etc. I’m always hesitant to substitute in something like this for fear the “nuts” will become soft. Do you think pistachios would work OK in this recipe?
Jill says
I haven’t tried pistachio nuts in this recipe. Jill
Selene Lun says
About how many sweet potatoes should I buy to make 3 cups of mashed sweet potatoes?
Peggy says
If I make it the day before, and refrigerate, how long in the oven with topping the next day? 10 minutes doesn’t seem long enough.
Jill says
If you bring it to room temperature, 10 minutes is fine. Jill
Eileen says
I’m curious about the potato type in this recipe. They aren’t orange at all, is that a special variety?
Cheryl Digman says
I was wondering the same thing myself so I looked it up and this white potato used in these pictures is just another type of sweet potato. I’ve only ever seen the orange ones. Very interesting….
