A savory sweet potato recipe that stands up tall at any table

This side dish is sure to wow at your next family get together! And it couldn’t be easier to pull together. To make this delicious savory sweet potato side dish you will need:

  • 3 lbs sweet potatoes peeled and thinly sliced into 1/8” rounds. THIN slices are key here. Too thick of inconsistent, and the potatoes won’t cook evenly. You can use a mandolin to cut them, or a sharp chef’s knife!
  • 2 medium red onions, thinly sliced. I like the sweetness the red onions bring, but you could use any onions you have on hand for this recipe. Just be sure they are thinly sliced.
  • Fresh rosemary. The herby flavor that this dish takes on can’t be replicated with the dry stuff (at least, for the. rosemary). Stick with fresh for this.
  • Grated smoked gouda cheese. The flavor is AMAZING, and it gets super crunchy on top on the oven. A win win.
  • Grated asiago cheese, which gives the dish a rich, nutty flavor.
  • And- some dried spices: smoked paprika ,ground sage, garlic powder, and good ol’ salt and pepper.
  • To pour over top, you’ll whisk up a mixture of heavy cream, melted butter, sour cream, milk, and cornstarch. The combo. is flavorful and rich, and the cornstarch helps the dish to thicken and set. Be sure to vigorously whisk so everything is well incorporated.

Chef’s notes:

Feel free to use lower fat milk (2%) or light sour cream in this recipe! Don’t skip the heavy cream, butter or cornstarch, though. It’s all about balance! And they are also key to the flavor and consistency of the dish.

A sweet potato casserole, made savory

I know a lot of people love a sweet potato casserole that’s well… sweet. And while those are delicious, there is something to be said about a savory sweet potato preparation. It lets the natural sweetness of the potatoes shine through. Think of this recipe as more of a cross between a sweet potato gratin and scalloped potatoes.

Can I make the sweet potatoes in advance?

Yes you can! You can bake layer them up and cover them for a few hours prior to baking, or bake the entire dish in advance and reheat. to reheat a previously baked casserole, cover it tightly with heavy duty foil, and reheat on a low temperature for about 30 minutes, until warmed through. Ideally 350 degrees or lower. Check on it periodically to make sure it isn’t overcooked.
