Ingredients

  • 3 Large Zucchini, sliced into ¼ inch slices
  • 1 teaspoon Kosher salt
  • ½ cup Heavy cream
  • 2 cups shredded Monterey Jack cheese
  • ½ teaspoon Italian seasoning
  • ½ Cup Shredded parmesan

Instructions

  • Pre-heat the oven to 400F
  • Toss the zucchini slices with the salt in a large bowl and let sit for at least 30 minutes.  Pat dry with paper towels. This will pull moisture from the zucchini so your casserole will not be watery.
  • In a small sauce pan, heat the heavy cream over medium heat.  Remove from the heat and add the cheese, stirring until melted.  
  • In a pie plate, arrange the zucchini in a circular pattern.  Pour the cheese mixture over the zucchini and sprinkle with the parmesan and Italian seasoning over top.  Bake in the oven for 30 minutes until the sauce starts to brown and becomes bubbly.  

Notes

 
  1. You could use any white cheese such as gruyere or Swiss instead of the Monterey jack.
