Description

A cozy, cheesy dish that cleverly uses summer squash and zucchini, perfect for those warm evenings.


Ingredients

Scale
  • 2 medium summer squash, sliced
  • 2 medium zucchini, sliced
  • 1 small onion, chopped
  • 2 to 3 cloves garlic, minced
  • 2 eggs
  • 1 cup Greek yogurt or cottage cheese
  • 1 to 1.5 cups shredded cheese (sharp cheddar or mozzarella)
  • A few spoonfuls of Parmesan cheese
  • 1 cup whole wheat breadcrumbs or panko
  • 1 to 2 tablespoons olive oil
  • Salt and pepper to taste
  • Optional: chopped basil or parsley, red pepper flakes, or a squeeze of lemon

Instructions

  1. Preheat your oven to 375°F and lightly oil a baking dish.
  2. Slice the summer squash and zucchini into thin rounds.
  3. Heat olive oil in a skillet, add the chopped onion and sauté for 3 to 5 minutes until softened.
  4. Add the minced garlic and stir for 30 seconds.
  5. Whisk the eggs in a bowl and stir in Greek yogurt or cottage cheese, most of the shredded cheese, Parmesan, salt, pepper, and herbs (if using).
  6. Add the sliced squash, zucchini, and onion-garlic mixture to the bowl and gently toss.
  7. Pour the mixture into the baking dish and spread it evenly.
  8. Mix breadcrumbs with olive oil and Parmesan for the topping, then sprinkle over the dish along with reserved shredded cheese.
  9. Bake for 30 to 40 minutes until the center is set and the top is golden.
  10. Let it rest for 10 minutes before slicing to ensure it sets firmly.

Notes

To prevent a watery casserole, salt and drain the squash before baking, and let the dish rest after cooking.
