Sweet Potato & Sausage Gratin w/ Thyme

Typically I’m not a big fan of sweet potatoes because they’re too sweet, but this dish is successfully savory.  In fact, it’s not only a great weekday side, this dish has claimed its spot in our Thanksgiving dinner repertoire – only the second dish to be added to our traditional feast in twenty years.


  • 3/4 pound sweet Italian sausages, casings removed
  • 1 1/3 cups canned low-salt chicken broth
  • 1 1/3 cups dry white wine
  • 1 1/3 cups apricot nectar
  • 4 tablespoons (1/2 stick) butter
  • 4 cups sliced leeks (white and pale green parts only; about 4 leeks, or 2 giant Texas-sized leeks)
  • 2 1/2 pounds tan-skinned sweet potatoes, peeled, thinly sliced
  • 2 tablespoons chopped fresh thyme or 1 tablespoon dried
  • 2/3 cup grated Parmesan cheese (about 2 ounces)


  • Preheat oven to 400°.
  • Cook sausages in heavy large skillet over medium-high heat until brown and cooked through, crumbling with back of spoon, about 6 minutes.  Using slotted spoon, place sausage in small bowl.
  • Pour off any drippings in skillet.  Add broth, wine, apricot nectar and 2 tablespoons butter to same skillet; boil until liquid is reduced to 1 1/2 cups, about 15 minutes.  Pour into another bowl.
  • Melt 2 tablespoons butter in same skillet over medium heat.  Add leeks and sauté until tender, about 10 minutes.
  • Arrange half of potatoes in 13x9x2-inch glass baking dish.  Sprinkle with half of thyme.  Season with salt and pepper.  Sprinkle with 1/3 cup cheese.  Top with half of leeks and all of sausage.  Cover with remaining potatoes.  Sprinkle with remaining thyme.  Season with salt and pepper.  Cover with remaining leeks.  Top with remaining cheese.  Pour broth over.
  • Cover and bake 30 minutes.  Uncover and bake until potatoes are tender and liquid thickens, about 15 minutes.  Cool slightly.

  1. This really is good. I deviate from the recipe in two places; I don’t put all of the sausage in the middle, I split it like everything else so the top potatoes get some juicy sausage runoff and I usually grate at least twice as much cheese because Parmesan is so good.
