How To Make Zucchini Parmesan Frittata

Here’s an overview of how to make it with the full recipe instructions at the bottom of this blog post.

  1. Prep Ingredients – Grate the zucchini with a cheese grater. Squeeze out the excess moisture from zucchini into paper towels. Whisk together eggs, milk and spices.
  2. Saute – Cook garlic, onion and zucchini in cast iron skillet for 8-10 minutes, or until juices have cooked down from zucchini.
  3. Add Eggs – Pour the egg mixture into the pan, stirring everything together. Let cook 2 minutes or until edges begin to golden.
  4. Broil – Sprinkle parmesan cheese on top of eggs. Broil for 2-5 minutes or until top is set and slightly browning.
  5. Serve – Slice and serve while still warm. This tastes great on its own or with salsa, sour cream, plain yogurt, hot sauce etc.

Storage: Leftovers should be stored in an airtight container in the fridge for 3-4 days or frozen for up to 3 months (Yes, you can freeze eggs!) Just reheat in the oven or microwave to serve.

Tips and Tricks

  • Squeeze Zucchini Before Cooking – Grated zucchini contains a lot of excess moisture. Add it to paper towels or a clean kitchen towel and squeeze out as much liquid as you can before cooking.
  • Use Fresh Parmesan – It really adds incredible flavor! I highly recommend using it instead of the jar version.
  • Eggs Cook Fast – The eggs only take a few minutes to cook so there’s no need to sautee them too long.
