Sweet Potato Gratins

Sweet Potato Gratins


  • Author: OliviaBennett

Description

Golden, cheesy, and bubbling with creamy comfort—these individual sweet potato gratins are pure magic in a ramekin. Thinly sliced sweet potatoes are bathed in garlicky cream, layered with nutty Gruyère, and finished with a crisp Parmesan crust. Elegant enough for holidays yet simple enough for weeknights, this dish transforms humble sweet potatoes into a show-stopping side everyone will crave.


Ingredients

Scale
  • 2 lbs sweet potatoes, peeled & thinly sliced

  • 1½ cups heavy cream

  • 2 cloves garlic, minced

  • ½ tsp salt

  • ¼ tsp black pepper

  • ¼ tsp nutmeg (optional)

  • 1 cup shredded Gruyère cheese (or sharp white cheddar)

  • 2 tbsp grated Parmesan cheese

  • Butter, for greasing ramekins

  • Optional: fresh thyme or rosemary


Instructions

  1. Prep: Preheat oven to 375°F (190°C). Butter ramekins generously.

  2. Infuse Cream: Warm cream with garlic, salt, pepper, and nutmeg until fragrant (do not boil).

  3. Layer: Arrange potato slices in ramekins, overlapping like shingles. Sprinkle Gruyère between layers.

  4. Pour & Top: Ladle warm cream over potatoes until just covered. Top with remaining Gruyère, Parmesan, and herbs if using.

  5. Bake: Cover loosely with foil; bake 30 min. Remove foil, increase heat to 400°F (200°C), and bake 15–20 min more, until golden and bubbling.

  6. Rest: Let gratins sit 5–10 min before serving for a creamy, set texture.

Notes

  • Apple & Sage: Add thin apple slices and use sage instead of thyme.

  • Smoky & Spicy: Use smoked Gouda + cayenne or paprika.

  • Dairy-Free: Sub full-fat coconut milk & vegan cheese.

  • Large Dish: Use a 2-qt baking dish if not using ramekins.
