Sweet Potato Gratin

  • Prep Time 0:25
  • Cook Time 0:50
  • Estimated Cost $11.50

I cannot stand marshmallow-y sweet potatoes. I realize they’re popular, but I happen to think they’re gross. Why would you cover up already sweet sweet potatoes with goopy, sugary marshmallows? I prefer my sweet potatoes contrasted with classic Fall-y savory ingredients—rosemary, onions, Parmesan. It doesn’t get any better than that. Bring this one out at Thanksgiving this year and help your guests forget the gelatinous sludge of Thanksgivings past.


  • 1 large or 2 medium sweet potato(es), skin on, sliced thinly $1
  • 1 large tart apple, such as Granny Smith, sliced into rounds $0.50
  • 1/2 onion, sliced $0.50
  • 1 tbsp fresh rosemary leaves, chopped (roughly 1 twig) $1
  • 3/4 cup sour cream $1.50 for 6 oz
  • 2/3 cup milk $1.50 for a pint
  • 2 tbsp unsalted butter, melted $1.50 for a stick
  • 1/4 cup grated Parmesan $4 for 10 oz.
  • salt and pepper to taste Pantry

Recipe Serves 3-4


  1. Preheat oven to 400 degrees F. Use the butter wrapper or a little olive oil to grease an 8" or 9" pie plate or square pan.
  2. Bring a pot of lightly-salted water to a boil. Add sliced sweet potatoes and reduce to a simmer. Cook for 6-8 minutes or until sweet potatoes are soft. Drain and cool slightly.
  3. Whisk together the sour cream, milk, melted butter, rosemary, salt and pepper to taste. Set aside.
  4. Arrange the sliced sweet potatoes, apples and onions in circling layers in the pan. Pour the sour cream-milk mixture over the entire pan, making sure to cover completely. Sprinkle with the Parmesan. Cover tightly with foil.
  5. Bake, covered with foil for 30 minutes. Remove foil and bake uncovered for 15-20 minutes, or until cheese is bubbly and browned in spots and potatoes are fully cooked.
  6. Serve hot.

Amen! Sweet potatoes aren’t my favorite, but pairing them with something even more sweet does them no favors.
