Ingredients

Sweet Potatoes
  • 2 medium sweet potatoes , washed, peeled and diced up to ½ inch pieces
  • 2 tablespoon butter or olive oil (for vegan)
  • 1 large shallot or 2 green onions
  • 1 teaspoon fresh Rosemary
  • 1 pinch salt and pepper
Gratin Topping
  • 1/2 cup all-purpose flour
  • ¼ cup freshly grated Parmesan cheese (skip if vegan)
  • 2 tablespoons fresh parsley minced
  • 4 Tablespoons butter or extra virgin olive oil(for vegan)
  • 1/4 cup crushed walnuts pistachios, pecans or hazelnuts

Notes

  • Cooking the sweet potatoes in the skillet without water or boiling intensifies the flavor so much.
  • You can however use leftover roast potatoes for this recipe.
  • Other veggies you can substitute are squash, potatoes, broccoli, zucchini or tomatoes for the summer!
  • The Gratin or Au Gratin is fancy for crunchy in french :) So don't feel intimidated to make this!
  • The crunchy topping can be made ahead of time and stored in the fridge for up to 5 days.
  • To make this a vegan sweet potato recipe : Simply swap the butter for olive oil, or coconut oil, and use vegan parmesan cheese.
  • To make the gratins ahead of time, you can assemble them and broil just before serving.
  • Likewise, you can prepare the whole gratin advance and warm in a 350 degree oven for 8 minutes before serving.
  • Use NUTS for an extra crunch in the topping : walnut, pecans, pistachios or hazelnut pair so well here!
  • You can make this gratin recipe into a large 2 quart dish, simply adjust broiling time.
  • Always keep an eye on the broiler because it can brown quickly!
