Ingredients

Here’s what you’ll need for 6 servings:

  • 6 large eggs
  • 1 cup milk or half and half
  • 1 cup shredded mozzarella cheese

  • 1 tablespoon olive oil
  • Salt, to taste
  • Black pepper, to taste

Ingredient Notes & Swaps

  • Milk vs. Half and Half: Half and half creates a richer texture.
  • Mozzarella: Fresh mozzarella can be used, but pat it dry first.
  • Basil: Fresh is essential for that bright flavor.
  • Onion: Optional, but adds depth.
  • Add-ins: Spinach, mushrooms, or cooked bacon make great additions.

Step-by-Step Instructions

1. Preheat

Preheat oven to 375°F (190°C). Grease a 9-inch pie or baking dish.

2. Sauté Aromatics

Heat olive oil in a skillet over medium heat. Sauté onion (if using) and garlic until softened and fragrant.

3. Mix the Egg Base

In a bowl, whisk together eggs, milk (or half and half), salt, and black pepper.

4. Add the Good Stuff

Stir in mozzarella, Parmesan, chopped basil, and the sautéed onion and garlic mixture.

5. Assemble

Pour the mixture into the prepared baking dish. Scatter halved cherry tomatoes evenly over the top.

6. Bake

Bake for 30–35 minutes, until the center is set and the top is lightly golden.

7. Rest & Serve

Let cool for about 5 minutes before slicing.

Serve warm or at room temperature.

Tips for Success

  • Don’t overbake — the center should be just set.
