Ingredients

Directions

Prepare

  1. Preheat oven to 350°F.

  2. In a medium bowl, whisk together eggs, Parmesan cheese, salt, pepper, and chives. Set aside.

Cook the vegetables

  3. Add the remaining tablespoon of oil to the skillet and cook the onions, tomato, and garlic for 5 minutes, or until the onions are tender.

  4. Return the zucchini to the skillet, evenly distributing it.

Bake and serve

  1. Add the egg mixture, and cook for 3 minutes, or until the bottom of the frittata is just set.

  2. Place the frittata in the oven and bake for 12 to 15 minutes, or until it is completely set and golden brown.

  3. Invert it onto a plate, cut into slices and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Set into a custard that gives the frittata its structure and body.
Parmesan cheese
Adds savory, salty flavor and helps the surface brown as it bakes.
Zucchini
Contributes moisture and tender texture that softens during cooking.
Vidalia onion
Adds sweetness and aroma as it softens in the oil.
Tomato
Adds moisture and bright acidity to the vegetable base.

The step that matters

Cook the zucchini until tender before adding the eggs. Zucchini releases water as it cooks. Cooking it through first evaporates excess moisture, so the egg mixture sets firmly rather than becoming watery or loose.

Swap the onion

How well each one fits the dish's main ingredients (egg, parmesan cheese, pepper, chive, olive, tomato, garlic):
