Can I prepare sweet potatoes ahead of time?

The answer is simply yes! We start with roasting the sweet potatoes in their jackets for easier peeling and slicing. Plus roasting them brings out their natural flavors. You can roast the sweet potatoes earlier in the day or even the prior day. Once the sweet potatoes are cool enough to handle, peel off their jackets. It should only takes minutes as they pull off in large sections. Or place the roasted sweet potatoes in their jackets in a container storing in the refrigerator.

Assembling the Make Ahead Sweet Potato Casserole

We start with making our cream sauce. In a heavy saucepan, melt the butter. Whisk in the flour until incorporated and then add the spices. Stir in the Chicken Broth, orange zest, salt and pepper. Lastly, stir in the heavy cream and remove from the burner.  

Spray a baking casserole with a non-stick spray. Next remove the sweet potatoes from their jackets. Slice to desired thickness layering in the prepared casserole pan. Pour the cream sauce over the top of the sweet potatoes. Cover and place in refrigerator. In a small bowl combine the breadcrumbs, pistachios, and cover.

Baking Make Ahead Sweet Potato Casserole

When you are ready to bake the Sweet Potato Casserole, remove from the refrigerator while preheating the oven. Remove saran wrap or any non oven safe material used to store the casserole. Top the casserole with breadcrumbs and pistachios mixture. Drizzle olive oil over the top. Cover and bake for 20 minutes. Then remove the cover and bake until sauce is bubbling. The actual baking time may take longer than 30 minutes if the sweet potatoes are still chilled from the refrigerator. 

I forgot to drizzle the olive oil over the top before baking. But it still came out good. An alternative to the breadcrumbs is pankos for more of a crunch.
