Crispy Panko Broccoli and Cauliflower Gratin

Heat oven to 425°F.

Butter a 10×8-inch oval baking dish or a dish of equivalent size.

Bring a large pot of generously salted water to a boil. Add the cauliflower and broccoli florets, and boil until slightly softened but still retaining some crispness, about 3 minutes. Drain well, and then slice the florets lengthwise so the stems are about 1/4 inch thick. Arrange the slices, overlapping them tightly, in the prepared baking dish. Season with salt and black pepper; dot with thin slices of the butter. Mix the cheese and bread crumbs together in a bowl, then sprinkle them over the top of the veggies. Then sprinkle 1 Tablespoon more of cheese on top.

Bake uncovered until lightly browned on top, about 30 minutes. Serve hot.
