Ingredients
- 4 large sweet potatoes
Sweet potatoes form the core of the casserole, providing a naturally sweet and creamy base, rich in vitamins and fiber. - 1/2 cup brown sugar
Brown sugar adds depth and moisture, enhancing the sweetness of the sweet potatoes while contributing to the casserole's rich flavor. - 1/3 cup milk
Milk serves to create a smooth and creamy mixture, balancing the sweetness and helping to achieve the desired consistency. - 1/2 teaspoon vanilla extract
Vanilla extract adds an aromatic element that elevates the overall flavor profile, bringing a warm, comforting essence to the dish. - 1/2 teaspoon cinnamon
Cinnamon not only adds a hint of warmth and spice, but also enhances the natural sweetness of the sweet potatoes. - 1/4 cup butter, softened
Butter enriches the mixture, providing a luscious texture while deepening the overall flavor of the casserole. - 1 cup mini marshmallows
Mini marshmallows create a sweet, gooey topping that caramelizes beautifully during baking, adding a nostalgic touch. - 1/2 cup chopped pecans
Pecans give a crunchy contrast to the soft sweet potato base, introducing a nutty flavor that rounds out the dish.
Directions & Preparation
Step 1: Preheat your oven to 350°F (175°C).
Preheating the oven ensures that your casserole bakes evenly from the start, allowing the sweet potatoes to meld with the other ingredients, creating a perfectly cooked dish.
Step 2: Peel and dice the sweet potatoes, then boil them until tender.
Boiling sweet potatoes makes them easy to mash and removes any bitterness. Make sure they are soft enough to easily break apart with a fork, which ensures a smooth texture in the final casserole.
Step 3: Drain the cooked sweet potatoes and return them to the pot.
Returning the potatoes to the pot allows residual heat to evaporate excess moisture, which helps achieve a velvety texture in the finished dish.
Step 4: Mash the sweet potatoes and mix in brown sugar, milk, vanilla extract, cinnamon, and butter until smooth.
This step is crucial for integrating all flavors. Make sure to mash thoroughly to avoid lumps, which could affect the casserole’s creaminess.
Step 5: Transfer the mixture into a greased baking dish.
Using a baking dish ensures even cooking and easy serving. Greasing prevents sticking, allowing for a clean release when ready to enjoy.
Step 6: Sprinkle mini marshmallows evenly on top of the sweet potato mixture, then finish with chopped pecans.
The topping adds visual appeal and an exciting texture contrast. The marshmallows will melt and brown, providing a delightful sweetness and gooey consistency.
Step 7: Bake for 25–30 minutes, or until the marshmallows are golden brown.
Baking allows the flavors to develop and meld together beautifully. Keeping an eye on the marshmallows ensures they achieve the perfect golden hue without burning.
Step 8: Remove from the oven and let it cool for a few minutes before serving.
Letting the casserole cool slightly will help it set, making it easier to serve. This brief resting period enhances the flavor, allowing the sweetness to fully emerge.

Elevating the Flavor with Spices
Incorporating spices like cinnamon and nutmeg can add aromatic warmth to your sweet potato casserole. These spices not only heighten the sweetness but also create a delightful contrast to the creamy texture. Experimenting with these spices allows personalization, making the dish even more special for your gatherings.
The Perfect Marshmallow Topping
Achieving the perfect golden-brown marshmallow topping is key to replicating the Ruth’s Chris experience. Ensure even coverage over the casserole so that every bite has that sweet, gooey element. For a twist, consider using different types of marshmallows or even a sprinkle of chocolate chips for a unique variation.
Crunch Factor with Pecans
Pecans add a satisfying crunch and a nutty flavor profile that balance out the dish's sweetness. Toasting the pecans before topping enhances their flavor, bringing extra richness to the casserole. This added texture makes each bite interesting, enhancing the overall tasting experience.
FAQs
What if my sweet potato mixture is too thick?
If your mixture is too thick, try adding a splash more milk to loosen it. Blend well until you achieve your desired creamy consistency.
Can I adjust the sweetness of this casserole?
Absolutely! You can reduce the brown sugar for a less sweet dish or substitute it with maple syrup for a different flavor profile.
Why is my casserole not browning on top?
If the top isn’t browning, it might need more time in the oven or a few minutes under the broiler. Be cautious, as it can burn quickly.
Is there a way to make this dish ahead of time?
You can prepare the sweet potato mixture and store it in the refrigerator for a day before baking. Just add the topping just before baking.
What alternative nuts can I use instead of pecans?
You can swap the pecans for walnuts or almonds if you prefer a different flavor or have nut allergies.
Can I make this without marshmallows?
Yes, you can replace marshmallows with a streusel topping made from oats, flour, and butter for a different yet delicious texture.
