Preheat your oven to 375°F (190°C).
In a large bowl, whisk together the 6 large eggs, 1/4 teaspoon of salt, and 1/4 teaspoon of black pepper.
Heat 1 tablespoon of olive oil in an oven-safe skillet over medium heat.
Add the diced medium onion to the skillet and sauté until it becomes translucent, about 5 minutes.
Pour the egg mixture into the skillet, ensuring it covers the onions evenly.
Sprinkle 1 cup of shredded cheese evenly over the top of the egg mixture.
Cook on the stovetop for about 2-3 minutes, until the edges start to set.
Transfer the skillet to the preheated oven and bake for 10-12 minutes, or until the frittata is fully set and the cheese is melted and slightly golden.
Remove from the oven and let it cool for a few minutes before slicing and serving.
