  • Onion Mixture
  • 3 tbsp olive oil
  • 4 large onions sliced pole to pole
  • ¼ tsp salt
  • ¼ tsp black pepper


  • 1 cup Pecorino Romano cheese finely grated
  • 3 tbsp olive oil
  • ½ cup panko bread crumbs
  • ½ tsp black pepper


  • 5 lbs Yukon Gold potatoes peeled & sliced into 1/8 inch slices
  • 2 cloves garlic minced
  • 1 tsp fresh thyme divided
  • 1 ¼ cup chicken broth divided
  • 6 tbsp olive oil
  • 1 tsp salt
  • ½ tsp black pepper


  1. Preheat oven to 400 degrees Fahrenheit.
  2. In a stainless fry pan, sauté the onion mixture on medium-low for about 40 minutes until well caramelized.
  3. Peel and slice potatoes and keep under damp paper towel or flour sack towel. This will keep them from turning brown.
  4. Create the topping mixture by combining the 4 ingredients and toss well to incorporate. Do not add any salt because the cheese is salty enough.
  5. Return to the onion mixture and add minced garlic and ½ tsp fresh thyme, cook for 30 seconds then add ¼ cup chicken stock to deglaze pan. Cook until all stock is evaporated.
  6. In a large bowl, combine potatoes, olive oil, salt, pepper and remaining ½ tsp fresh thyme.
  7. Coat a 9x13 baking dish with cooking spray or olive oil.
  8. Layer ½ of the potato mixture in baking dish.
  9. Spread all of the onion mixture on top of the potato layer, evenly.
  10. Add remaining potatoes, layered on top of onion mixture.

  11. Pour ¾ cup of chicken broth over the potato/onion mixture.
