Ingredients

Scale

Vegetables:

  • 4 medium zucchinis, chopped into bite-sized pieces
  • 1 cup cherry tomatoes, halved
  • 1 small onion, diced
  • 23 cloves garlic, minced

Cheeses:

  • 1 cup shredded mozzarella cheese
  • 1/2 cup shredded cheddar cheese
  • 1/2 cup grated Parmesan cheese

Other Ingredients:

  • 1 tbsp olive oil
  • 1 cup heavy cream or half-and-half
  • 2 large eggs
  • 1/2 tsp dried oregano
  • 1/2 tsp dried basil
  • Salt and pepper to taste
  • Fresh parsley or basil for garnish (optional)

Instructions

  1. Prepare the Oven and Dish: Preheat your oven to 375°F (190°C). Lightly grease a medium-sized baking dish to prevent sticking and ensure easy serving.
  2. Sauté the Vegetables: Heat olive oil over medium heat in a skillet. Add diced onion and cook until tender and translucent (~3-4 minutes). Add minced garlic and cook for another minute until fragrant, building a flavorful base.
  3. Add the Zucchini and Tomatoes: Stir in chopped zucchini and halved cherry tomatoes. Cook for 5-7 minutes, stirring occasionally, until zucchini softens but retains shape. Season with salt, pepper, dried oregano, and basil, then remove from heat.
  4. Mix the Cream and Eggs: In a large bowl, whisk together heavy cream (or half-and-half) and eggs until smooth. Stir in half of the mozzarella, cheddar, and Parmesan cheese to create a creamy filling.
  5. Combine Everything Together: Add the sautéed vegetables into the cream and cheese mixture. Gently stir to evenly distribute the flavors and ingredients.
  6. Assemble the Casserole: Pour the combined mixture into the prepared baking dish, spreading it evenly. Top with the remaining shredded cheeses for a cheesy crust.
  7. Bake to Perfection: Bake in the preheated oven for 25-30 minutes until bubbly and golden brown on top, filling your kitchen with a delicious aroma.
  8. Let It Cool: Remove from the oven and let the casserole rest for about 5 minutes to set, helping it hold together when served.
  9. Serve and Enjoy: Garnish with fresh parsley or basil if desired, then serve warm. Perfectly cheesy and tender, enjoy with family or friends!

  • For a lighter version, use milk or a dairy-free alternative instead of heavy cream.
  • Eggs can be substituted with a flax egg for an egg-free option.
  • Avoid overcooking zucchini during sautéing to keep the casserole from becoming soggy.
  • Leftovers store well in an airtight container in the fridge for up to 3 days.
