  • Total Time: 45 minutes
  • Yield: 4 servings

Ingredients

Vegetables

  • 3 cups sliced yellow squash (can also use zucchini or a combination of both)
  • 1 small onion, sliced
  • 2 cloves garlic, minced

Wet Ingredients

  • 2 tablespoons water
  • 1 large egg, lightly beaten
  • 6 tablespoons milk (1/4 cup + 2 tablespoons)
  • 3 tablespoons butter, melted and divided

Dry Ingredients

  • 18 Ritz Crackers, crumbled
  • 1/2 cup shredded cheddar cheese
  • 2 teaspoons dried parsley
  • 2 teaspoons freshly chopped basil
  • 1/2 teaspoon dried oregano
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon pepper

Instructions

  1. Preheat Oven and Prepare Dish: Preheat your oven to 400°F (204°C) and spray a 1 1/2 quart baking dish with cooking spray to prevent sticking.
  2. Sauté Vegetables: In a large skillet, combine the sliced yellow squash, onion, minced garlic, and 2 tablespoons of water. Cover and cook over medium heat for about 5 minutes until the squash and onions become slightly tender. Drain any excess liquid and transfer the vegetables to a large mixing bowl.
  3. Mix Egg and Milk: In a small bowl, whisk together the lightly beaten egg and milk until fully blended. Add this mixture to the cooked squash and onions in the large bowl.
  4. Prepare Cracker Topping Mixture: In a medium bowl, combine the crumbled Ritz crackers, shredded cheddar cheese, dried parsley, and 1 tablespoon of the melted butter. Mix well; the mixture will look somewhat dry. Add half of this cracker mixture to the bowl with the squash mixture.
  5. Combine Seasonings and Butter: Add the remaining 2 tablespoons of melted butter, freshly chopped basil, dried oregano, kosher salt, and pepper to the squash mixture. Stir until everything is well combined. Pour this filling evenly into the prepared baking dish.
  6. Top and Bake: Evenly sprinkle the remaining cheese and cracker topping mixture over the squash filling in the baking dish. Bake uncovered in the preheated oven for 25 minutes or until the topping is golden brown and the casserole is heated through.

Notes

  • You can substitute zucchini or use a combination of yellow squash and zucchini depending on availability and preference.
  • For a lighter option, you may use low-fat milk and reduce the cheese amount slightly.
  • Let the casserole rest for a few minutes after baking to set before serving.
  • Spraying the baking dish ensures easy cleanup and prevents sticking.
