How to Make Million Dollar Sweet Potatoes (Sweet Potatoes Royale) Recipe

Step 1: Prepare Your Oven and Sweet Potato Base

Start by preheating your oven to 350°F so it’s ready when you finish prepping. In a large bowl, combine the cooked and mashed sweet potatoes and stir them until perfectly smooth. This creamy base will support all the other delicious layers to come.

Step 2: Mix the Sweet Potato Filling

Add the beaten eggs, apple butter, heavy cream, vanilla extract, ground nutmeg, ¼ cup of the brown sugar, ¼ cup of melted butter, and 1 teaspoon of kosher salt to the sweet potatoes. Stir everything together until the mixture is well combined and silky smooth. This blend will create the luscious, flavorful custard inside your casserole.

Step 3: Assemble in Your Baking Dish

Spoon the filling into an ungreased 10-inch cast iron skillet or casserole dish, smoothing it evenly so the top is flat. Then, lovingly arrange the large marshmallows over the surface to make that iconic gooey topping that’s sure to delight.

Step 4: Prepare and Add the Crunchy Topping

In a medium bowl, stir together the pecan halves, coconut flakes, flour, cinnamon, the remaining ½ cup brown sugar, and ½ teaspoon kosher salt. Add the remaining ¼ cup melted butter, and mix until all the dry ingredients are evenly coated and form little clusters. Scatter this fabulous topping evenly over the marshmallows for a crunchy, sweet contrast.

Step 5: Bake to Perfection

Bake your casserole until it’s hot and bubbling around the edges, the marshmallows are delightfully golden brown, and the center is set—no longer loose or wet. This usually takes about 30 to 35 minutes. The smell alone will make your kitchen feel like home!

Side Dishes

Million Dollar Sweet Potatoes (Sweet Potatoes Royale) Recipe pairs beautifully with savory mains like roast turkey, glazed ham, or southern fried chicken. Creamy mashed potatoes or a crisp green salad also balance the sweetness and richness wonderfully.

Creative Ways to Present

For holiday dinners, try serving the casserole in individual ramekins or mini skillets for a personal touch. You could also layer the sweet potato mixture and topping in a clear glass dish for a stunning display of colors and textures that guests will admire before tasting.

Make Ahead and Storage

Storing Leftovers

Store any leftover sweet potato casserole in an airtight container in the refrigerator for up to 3 days. Covering it well helps maintain moisture and keeps those marshmallow tops just as tempting when you reheat.

Freezing

This recipe freezes beautifully. Wrap the cooled casserole tightly with plastic wrap and foil, then freeze for up to 2 months. This makes it a perfect make-ahead dish for busy times or unexpected guests.

Reheating

Reheat leftovers in the oven at 325°F until warmed through, about 20 minutes. This helps preserve the crispy topping and brings back that freshly baked flavor and texture better than a microwave could.

FAQs

Can I use canned sweet potatoes for this recipe?

While fresh sweet potatoes offer the best texture and flavor, canned sweet potatoes can be used in a pinch. Just make sure to drain and mash them thoroughly to avoid excess moisture diluting the batter.

Is there a way to make this recipe vegan?

You can swap eggs for flax eggs, use coconut cream instead of heavy cream, and replace butter with vegan margarine. For marshmallows, find vegan alternatives or omit them and add extra pecans and coconut for crunch.

Can I prepare the topping in advance?

Yes! You can mix the pecan, coconut, and flour topping a day ahead and store it in an airtight container. Then sprinkle it on just before baking to keep it fresh and crunchy.

What can I substitute for apple butter?

If you don't have apple butter, you can use pumpkin puree or apricot preserves to maintain a similar fruity sweetness and creamy texture in the filling.

How do I know when the casserole is done baking?

The casserole is ready when the edges are bubbling and the marshmallows have turned golden brown, while the center feels firm and set rather than watery. A toothpick inserted in the middle should come out mostly clean.
