There’s much to love about this dish, starting with layers of perfectly cooked squash intermingled with an irresistible herb-kissed cream cheese sauce. Adding flavor and crunch is a parmesan-pork panko topping. Together, they make an epic side dish that’s approachable for weeknight meals but worthy of special occasions

  • Servings:


  • 3 tbsp olive oil divided
  • 3 medium zucchini sliced into 1/4-inch-thick disks
  • 3 medium yellow squash sliced into 1/4-inch-thick-disks
  • 1 tsp onion powder
  • salt
  • pepper
  • 1 tsp dried thyme oregano or basil
  • 1/2 cup heavy cream
  • 4 oz cream cheese cut into small pieces

  1. Preheat the oven to 450°F (230°C). Grease a 2-quart baking dish with 2 teaspoons of the olive oil.

  4. Spoon the mixture into a shallow 2-quart baking dish.
  5. In a small bowl, combine the remaining Parmesan cheese with the pork panko and season with 1/2 teaspoon salt and 1/4 teaspoon pepper.
  6. Sprinkle the squash with the Parmesan-panko mixture and bake until the top is golden brown and bubbling, about 10 minutes. Serve right away.
