Step 1

Preheat your oven to 400℉.

Step 2

In a mixing bowl whisk together eggs, heavy cream, parmesan cheese, and 1/2 tsp salt.

Step 3

In an oven-proof skillet heat the olive oil over medium heat. Add the onions, zucchini, mushrooms, remaining 1 tsp salt, and pepper. Sauté for 5-8 minutes until soft and the moisture has come out and mostly evaporated.

Step 4

To the skillet with the sautéd veggies, add the egg mixture and spread everything into an even layer.

Step 5

Bake for 20-30 minutes until the center is set.

Step 6

Once you remove it from the oven, let it sit for at least 15 minutes before slicing. Serve with fresh chives and more parmesan cheese if desired.
