The Story & Intro of Sweet Potatoes Au Gratin
A dish that reminds me of Grandma’s table
The first time I tried Sweet Potatoes Au Gratin, I was eight years old, sitting at my grandmother’s kitchen table. She pulled the bubbling casserole out of the oven, golden cheese crisping at the edges, and the warm scent of nutmeg and cream filled the room. Unlike the usual mashed potatoes, this dish had texture, layers, and flavor that danced between sweet and savory. I remember asking for seconds—and thirds.
Grandma’s version of Sweet Potatoes Au Gratin was rich, yet not overwhelming. She sliced her sweet potatoes paper-thin, layered them like a lasagna, and poured a homemade béchamel sauce in between each tier. The top was a mix of gruyère and sharp cheddar, baked to perfection. That memory has stayed with me and inspired me to recreate—and modernize—her recipe for today’s kitchens.
Now, whenever I make Sweet Potatoes Au Gratin, I feel connected to those early food memories. It’s not just about taste—it’s about tradition.

Crafting the Perfect Sweet Potatoes Au Gratin
Choose the right potatoes
You might think any sweet potato will do—but for the best Sweet Potatoes Au Gratin, go with orange-fleshed varieties like Beauregard or Garnet. These have the perfect balance of sweetness and creaminess and hold their shape well during baking.
Slice your potatoes thinly—1/8 inch or less. A mandoline slicer works best here for even layers. Uniform slices not only look good but ensure even cooking, a crucial detail if you want your Sweet Potatoes Au Gratin to turn out perfectly every time.
Cream, cheese, and seasoning—where flavor is born
This dish is all about creamy indulgence. The sauce usually starts with heavy cream and sometimes a bit of whole milk. To this, add a touch of garlic, fresh thyme, a pinch of cayenne, and ground nutmeg. These spices balance the natural sweetness of the potatoes.
As for cheese, gruyère is a classic choice, offering a nutty sharpness. You can blend it with white cheddar or parmesan for depth. The key is melting quality. Choose cheeses that melt smoothly for that silky, luscious bite.
Before layering, lightly butter your baking dish and rub it with a clove of garlic. This subtle step infuses the base with added aroma.
Place a layer of sweet potatoes, pour a bit of cream sauce, sprinkle with cheese, and repeat until the dish is full. Cover with foil and bake for 45 minutes. Then remove the foil and bake uncovered until the top is golden brown.
Serve it warm alongside dishes like biscuit breakfast casserole or veggie breakfast casserole for a full brunch experience.
