Step 3: Layer the Cheese
Sprinkle the shredded cheddar cheese evenly over the top. Sharp cheddar adds a tangy contrast to the sweetness of the potatoes and creates a golden, melty crust during baking.
🔄 Variation: Try Gruyère for a nuttier, more sophisticated flavor.
Step 4: Dot with Butter
Place small pats of butter over the top of the cheese layer. As the casserole bakes, the butter will melt down into the layers, adding richness and helping to create a lightly crisped top.
Step 5: Season (Optional but Recommended)
Add a pinch of salt and freshly ground black pepper. For a cozier, autumnal flavor, sprinkle a touch of cinnamon or nutmeg over the top. Herbs like rosemary or thyme can be added now or as a garnish after baking.
Step 6: Cover and Bake
Cover the dish tightly with aluminum foil. Bake in the preheated oven at 375°F (190°C) for about 40 minutes. This allows the sweet potatoes to steam and soften in the cream.
Step 7: Uncover and Finish Baking
Remove the foil and bake uncovered for an additional 15–20 minutes. This helps the top layer of cheese and butter brown beautifully, and the cream will thicken into a silky sauce.
🧑‍🍳 Pro Tip: If you want an extra-crispy top, broil for the last 2–3 minutes—just keep a close eye to prevent burning.
Serving and Storage
Let the casserole rest for about 10 minutes before serving. This helps the sauce thicken further and allows the flavors to meld.
Serve it as a:
- Side dish with roasted meats or poultry
- Vegetarian main with a crisp salad
- Brunch item with eggs or toast
Leftovers keep well in the refrigerator for 3–4 days and reheat beautifully in the oven or microwave.
