This savory pear, apple, and red onion gratin recipe is perfectly suited to a cozy supper by the fire on a chilly night. Caramelized red onions provide an intense sweetness with just the right amount of sharpness to offset the orchard-fresh flavor of the apples and pears. That combination mixed with aromatic thyme and an unexpected cheesy topping makes for a heavenly side dish. Because of its festive color and delicious versatility, it makes for an ideal holiday or special occasion side dish.


  • For the Gratin:
  • 1 tablespoon olive oil
  • 1 large red onion (thickly sliced)
  • 2 medium Bosc pears
  • 2 medium baking apples
  • 1 1/4 teaspoons thyme
  • 1/2 teaspoon salt
  • 1/8 teaspoon black pepper
  • For the Topping:
  • 1 cup breadcrumbs (thick Panko are best)
  • 1/3 cup parmesan cheese (grated)
  • 2 tablespoons butter (melted)

Steps to Make It

  1. Gather the ingredients.
  2. Preheat the oven to 400F.
  3. In a large skillet set over medium-high heat, sauté the red onions until they start to brown around the edges. Transfer them into a casserole dish and set it aside for a moment.
  4. Core the apples and pears, and cut them into thick wedges. Toss the apples and pears with the reserved onions, thyme, salt and pepper. Bake the gratin, covered, for 25 to 30 minutes.
  5. Stir together the breadcrumbs, cheese, and melted butter. Sprinkle the topping over the pear onion gratin and bake it, uncovered, for an additional 25 minutes, or until the fruit is tender, the topping is golden brown, and the gratin is bubbling hot.
