Ingredients

  • 1 leek (rinsed and sliced)
  • 2 green zucchini (sliced diagonally)
  • 2 yellow zucchini squash (sliced diagonally)
  • 4 tablespoons olive oil
  • 1 teaspoon kosher salt
  • pepper to taste
  • 3/4 cup fresh or panko bread crumbs
  • 1/2 cup shredded parmesan cheese
  • 1/2 teaspoon garlic powder
  • fresh snipped parsley

Instructions

  • Preheat oven to 400 degrees F.
  • Spray a 9 inch round pie pan with non-stick spray. Set aside.
  • Prepare the leek by rinsing well under cold running water. Let drain. Slice thinly.
  • Cut the 4 zucchinis into diagonal slices about 3/8 inch thick.
  • In a large bowl, combine the sliced leek, sliced zucchini, 1 teaspoon salt, pepper to taste, and 4 T. olive oil.
  • Mix well with a large spoon or clean hands. Set aside.
  • In a small bowl, combine bread crumbs, parmesan, garlic powder, and parsley. Set aside.
  • In the prepared pie plate, arrange the zucchini in a circular pattern, overlapping the pieces. You will need two layers.
  • Mix the leek in and under the layers as best you can. It will not be perfect!
  • Top the zucchini layers with the bread crumb mixture.
  • Drizzle with additional olive oil.
  • Bake for 30 minutes.
  • Watch closely and if topping browns too quickly, cover with aluminum foil.
  • Remove from oven and let rest for 5 to 10 minutes.
  • Serve as a side dish with fish, beef, or chicken.
