Source: Everyday Food, May 2007


  • 2 tablespoons butter
  • 2 medium zucchini (about 7 ounces each), sliced crosswise 1/4 inch thick
  • 2 medium yellow squash (about 7 ounces each), sliced crosswise 1/4 inch thick
  • 2 shallots, minced
  • 2 garlic cloves, minced
  • Coarse salt and ground pepper
  • 1/2 cup heavy cream
  • 1 cup panko
  • 1/2 cup grated Parmesan cheese


  1. Preheat oven to 450. In a large skillet, melt butter over medium heat; add zucchini, yellow squash, shallots, and garlic. Season with salt and pepper. Cook, stirring occasionally, until zucchini and squash are crisp-tender, 4 to 6 minutes.

  2. Add cream, and cook until thickened, about 5 minutes. Remove skillet from heat; stir in 1/2 cup panko and 1/4 cup Parmesan.

  3. Spoon mixture into a shallow 2-quart baking dish. Sprinkle with remaining panko and Parmesan; season with salt and pepper. Bake until top is golden, 8 to 10 minutes.
