SAVORY COBBLER WITH CHEDDAR BISCUIT TOPPING

Steps:

• For the vegetables: Position an oven rack in the lower third of the oven and preheat to 350 degrees F. Grease a 9-by-13-inch baking dish with 2 tablespoons olive oil.
• Stir together the Parmesan, parsley, rosemary, thyme, 2 teaspoons salt and 1/2 teaspoon pepper in a medium bowl.
• Spread the eggplant in a single layer on the bottom of the prepared baking dish, cutting rounds in half or overlapping slightly if necessary. Scatter 1/4 cup of the Parmesan mixture over the top of the eggplant. Top with a single layer of tomato slices, then scatter the corn kernels in an even layer over the tomatoes and follow with another 1/4 cup of the Parmesan mixture. Add a single layer of the yellow squash slices, then break the onions into rings and scatter over the top. Layer over the bell pepper, then another 1/4 cup of the Parmesan mixture; top with a layer of zucchini slices and finish with an even sprinkling of the remaining Parmesan mixture. Drizzle the remaining 2 tablespoons olive oil over the top.
• For the biscuit topping: Whisk together the flour, baking powder, sugar, baking soda, 1 teaspoon salt and 1/4 teaspoon pepper in a large mixing bowl. Grate the cold butter on the large holes of a box grater and stir into the flour mixture so all the butter pieces are coated with flour. Stir the Cheddar and scallions into the flour mixture. Make a well in the center, then add the sour cream and milk to the well and stir with a wooden spoon just until the ingredients are moistened. Using a cookie scoop or large serving spoon, drop scant 1/2-cup mounds evenly spaced over the top of the vegetables.
• Bake until the biscuits are deep golden brown, the filling is bubbling along the edges and the vegetables give easily when pierced with a knife, about 1 hour. Brush the tops of the biscuits with the melted butter and let rest for 20 minutes before serving.
