Herbed Summer Squash and Potato Torte

From Smitten Kitchen. A good use for the summer squash overflowing from our garden. Note the recipe makes 2 8" pans, not just 1.

Makes 8 servings

1 bunch green onions, thinly sliced
1 cup grated Parmesan cheese
2 tablespoons all purpose flour
1 tablespoon chopped fresh thyme
1 1/2 teaspoons salt
3/4 teaspoon ground black pepper

2 pounds Yukon Gold potatoes, peeled, cut into 1/8-inch-thick rounds
12 ounces yellow crookneck squash or regular yellow summer squash, cut into 1/8-inch-thick rounds
6 teaspoons olive oil

Preheat oven to 375°F. Grease two 8-inch-diameter cake pans. Set aside 1/4 cup sliced green onions. Toss remaining green onions, cheese, flour, thyme, salt and pepper in medium bowl to blend.

Layer 1/6 of potatoes in concentric circles in bottom of 1 prepared pan, overlapping slightly. Layer 1/4 of squash in concentric circles atop potatoes. Drizzle with 1 teaspoon oil. Sprinkle with 1/6 of cheese mixture. Repeat with 1/6 of potatoes, then 1/4 of squash and 1 teaspoon oil. Sprinkle with 1/6 of cheese mixture. Top with 1/6 of potatoes. Drizzle with 1 teaspoon oil. Sprinkle with 1/6 of cheese mixture and press gently to flatten. Repeat procedure with second cake pan and remaining potatoes, squash, oil, and cheese mixture.

Cover pans with foil. Bake until potatoes are almost tender, about 40 minutes. Remove foil; bake uncovered until tortes begin to brown and potatoes are tender, about 25 minutes longer.

Cut each torte into wedges. Sprinkle wedges with 1/4 cup green onions; serve.
