Crispy Onion and Herb Frittata

1.In a medium bowl, whisk together the eggs, chopped parsley, grated parmesan, salt, and black pepper until well combined.

2.Heat the olive oil and butter in a 8-inch non-stick skillet over medium-high heat.

3.Add the sliced onions to the skillet and sauté for 5 to 7 minutes, stirring frequently, until they are soft and golden brown with crispy edges.

4.Reduce the heat to medium-low and spread the onions evenly across the bottom of the skillet.

5.Pour the egg mixture over the onions, ensuring it coats the entire pan evenly.

6.Cook undisturbed for 3 to 4 minutes until the edges are set and the center is mostly firm.

7.Carefully slide the frittata onto a plate or flip it if desired, cooking for an additional 1 minute until the center is fully set, then serve immediately.
