Serves 4-6

3 Tbsp. olive oil
4 small red potatoes, unpeeled and cut into wedges
1 large onion, sliced
2 medium sweet potatoes, peeled and cut into 1-inch chunks
4 carrots, cut into 2-inch long pieces (and cut in half lengthwise if thicker than your thumb)
4 green onions, trimmed and chopped into 1/2-inch pieces
Fine-grain sea salt and freshly ground black pepper
1 pear, unpeeled, cored, and cut into 6 wedges
1/2 cup panko (or bread crumbs)
2/3 cup fresh Parmesan cheese (grated or shaved)

1. Preheat oven to 375 degrees Fahrenheit and position a rack in the middle of the oven.

2. Heat olive oil in your largest ovenproof skillet over medium-high heat. In a single layer, add the potatoes, onions, sweet potato, carrots, and green onions and toss to coat. Try not to overcrowd the pan, or the vegetables will steam and not brown. If you don't have a big enough pan, split the ingredients between two skillets. Saute over medium-high heat for about 15 minutes, shaking the pan a couple of times along the way. The vegetables should start to brown a bit and be tender but not mushy.

3. Remove from heat and sprinkle with a generous dose of salt and pepper. Stir in the pear wedges.

4. If you don't have an ovenproof skillet, transfer the ingredients to an ovenproof baking dish or casserole. Sprinkle with all the panko and half of the Parmesan cheese (don't stir).

5. Place uncovered in the oven. Bake for about 40 minutes, tossing the vegetables with a metal spatula about halfway through. The potatoes and carrots should be golden, crispy, and caramelized where they touch the pan and soft and tender inside. When everything is caramelized and fragrant, remove from the oven and sprinkle with the remaining Parmesan. Serve.
