Thanks Tiffany for sharing this recipe!
Makes an 11-in skillet or larger au gratin dish, depending on how tightly layers are arranged.
Original recipe here (doesn't include eggplant):
Ingredients
2 zucchini, sliced into rounds about ¼-inch thick
2 eggplant (ideally close to the same diameter of the zucchini), sliced into rounds about ¼-inch thick
3 or 4 smallish medium-sized potatoes (ideally, close to the diameter of the zucchini), peeled and sliced into rounds about ⅛-inch thick
2 smaller red onions, thinly sliced into rounds (if too large, cut in half)
Salt and pepper
2 tsp dried oregano
scant 1 tsp dried rosemary
½ cup chopped fresh parsley
4 garlic cloves, minced
Extra virgin olive oil
1 2 8-oz canned unsalted diced tomatoes with juice
Directions
1. Preheat oven to 400 degrees F. Place a rack in the middle.
2. Place sliced potatoes and zucchini in a large mixing bowl. Season with kosher salt, pepper, oregano, and rosemary. Add fresh parsley, garlic, and a generous drizzle extra virgin olive oil. Toss to make sure the vegetables are well coated with the EVOO and spices.
3. Grab a large round pan on skillet (An 11-inch oven safe pan, a skillet, or an au gratin dish) Pour ½ of the canned diced tomatoes in and spread to cover the bottom of the pan. Season with salt and pepper
4. Arrange the seasoned eggplant, potatoes, zucchini, and sliced onions in the pan in rows (simply going around the shape of the pan and alternating.)
5. If you have any of the extra virgin olive oil and garlic mixture left in the mixing bowl, pour that all over the veggies, then top with the remaining diced tomatoes from your can.
6. Cover the pan with foil (tent foil a bit so it is not touching the veggies). Bake in 400 degrees F heated-oven for 45 minutes. Take pan out briefly to carefully remove foil, then place back in oven, uncovered, and roast for another 30-40 minutes or until the veggies are soft and charred and most of the liquid has evaporated. (ovens do vary, so pay attention and check as needed.)
7. Remove from oven. Serve warm or at room temperature with an added generous drizzle of extra virgin olive oil. This dish goes great with feta, olives, pita, and/or rice.
