  • 10 slices bacon, chopped
  • 1 medium onion, chopped
  • 2 cups heavy whipping cream
  • 1 cup chicken broth
  • 1 tablespoon finely chopped fresh thyme leaves
  • 3 cloves garlic, finely chopped
  • 1 1/2 teaspoons salt
  • 1/2 teaspoon pepper
  • 3 1/2 lb (1.6 kg) sweet potatoes, peeled, cut into 1/4-inch slices
  • 1 cup grated Parmesan cheese
  • 2/3 cup plain panko crispy bread crumbs
  • 2 tablespoons butter, melted


  • 1
    Heat oven to 375°F. Spray 13x9-inch (3-quart) baking dish with cooking spray.
  • 2
    In 12-inch skillet, cook bacon over medium heat 18 to 22 minutes, stirring occasionally, until crisp. Drain on paper towels. Reserve 1/4 cup bacon for garnish. Reserve 1 tablespoon drippings in skillet.
  • 3
    Add onion to skillet with drippings; cook over medium heat 5 to 7 minutes or until softened.
  • 4
    In 5-quart Dutch oven, add whipping cream, broth, cooked onions, thyme, garlic, salt and pepper. Heat to boiling over medium heat. Add sweet potatoes; cook 5 minutes, stirring occasionally
  • 5
    In baking dish, layer half of the sweet potato mixture, half of the bacon and 1/2 cup of the Parmesan cheese. Repeat with remaining sweet potato mixture, bacon and Parmesan cheese. Spoon any remaining cream mixture over top. Cover with foil; bake 10 minutes
  • 6
    Meanwhile, in small bowl, mix bread crumbs and melted butter. Stir to coat.
  • 7
    Remove foil; sprinkle bread crumb mixture over top. Bake uncovered 20 to 25 minutes or until potatoes are tender, top is browned and edges are bubbly. Remove from oven; let stand 15 minutes before serving. Garnish with reserved bacon and, if desired, a light sprinkling of chopped fresh thyme.

Expert Tips

  • Tip 1
    Make sure to get the red-skinned, orange-fleshed sweet potatoes for this dish.
  • Tip 2
    Resist the urge to use half-and-half or milk in place of the cream, as it tends to break and result in a sauce with a curdled appearance.
