These sweet potatoes with cinnamon and brown sugar butter are a mashup of copycat recipes to our favorite steak houses’ (Longhorn and Texas Roadhouse) sweet potatoes. These Sweet potatoes are done in a super easy crockpot method and then topped with brown sugar and cinnamon butter and with the optional marshmallows, are then broiled on a cast iron skillet for a crisp and gooey topping. See below the recipe for notes and photos.

- Rinse the sweet potatoes and place into the bottom of a 6-7 quart crockpot. Add 1/4 cup water(*See note below) and cook on high for 3.5-5 hours or on low for 6-8 hours, until the sweet potatoes have softened to preference.
- Once the sweet potatoes have softened, mix the butter, cinnamon, brown sugar and salt with a hand mixer until well combined and smooth. Add confectioners sugar and mix until the brown sugar butter has a little more volume. Serve the sweet potatoes plain with the brown sugar and cinnamon butter, or complete step below.
- Optional step: cut a slit length-wise into the top of a cooked sweet potato and fill with the brown sugar and cinnamon butter, place marshmallows into the cavity and then broil at 450 degrees for 20-30 seconds, or until the marshmallows have browned to your preference. Enjoy! Keep scrolling for notes and photos.
Most recipes don’t recommend extra water in the crockpot other than the moisture left behind from rinsing the sweet potatoes. I personally found clean up to be easier if I added a splash of water. Feel free to try out the method of your choice!
The Brown sugar and cinnamon butter can be prepped ahead and left at room temperature (to keep its softness) for 1-2 days.
I prefer to add the toasted marshmallows to my sweet potatoes, but my husband prefers his plain with the brown sugar and cinnamon butter. The last step is completely optional, feel free to customize your sweet potatoes to preference!
