Description

A Zucchini Frittata is a great breakfast, brunch, or dinner and this recipe is about as easy as it gets. In just about 45 minutes, you can have this tasty Italian dish on your plate.


Ingredients

Units Scale
  • 3 tablespoons extra-virgin olive oil
  • 2 cups chopped zucchini (1 medium or medium-large zucchini or about 9 ounces)
  • 1/2 cup chopped onions (2 ounces)
  • 2 garlic cloves, minced
  • 1/2 teaspoon salt
  • 1/2 teaspoon pepper
  • 1 teaspoon dried thyme or 1 tablespoon fresh thyme
  • 1/2 cup whole milk
  • 8 eggs
  • 4 ounces cheddar cheese, shredded

Instructions

  1. Preheat oven: Position a rack in the top third of the oven and preheat to 350° Fahrenheit
  2. Add olive oil:  Add oil to cast iron pan and heat to medium to medium-high
  3. Add zucchini, onion, and garlic: Mix and cook zucchini, onion, and garlic.
  4. Add salt, pepper, and thyme.
  5. Cook zucchini: Cook until zucchini is glassy
  6. Whisk milk and eggs: While zucchini is cooking mix together milk and eggs. Use a hand whisk, but don’t overwhisk. Whisk only until everything is combined.
  7. Add cheese: Mix in cheese to the milk and egg mixture. 
  8. Once zucchini is glassy, add egg mixture to pan.
  9. Cook on stovetop: Cook until edges start to separate from the skillet. I stir in the middle a bit to help make sure it doesn’t burn. When done, eggs will start to look like they have some doneness, but still be mostly uncooked.
  10. Bake: Bake for 15 to 25 minutes on the upper rack, checking at 15 minutes. The frittata is ready when the center is set and reaches 160°F.
  11. Remove from oven: Remove and allow to cool for five minutes.

Notes

  • Check out the rest of the post, but there are many opportunities for substitutions in this recipe
  • To determine when to place in the oven, use the spatula to determine when the edge of eggs is easily separated from the edges of the pan.
  • You can test for doneness by placing a toothpick in the center. If it comes out mostly clean with no runny egg, it should be done.
  • Allowing to rest for 5 minutes is important to finish the bake.
