1 ½ cups shredded cheddar cheese
1 cup shredded mozzarella cheese

1 cup sour cream
2 large eggs
2 tablespoons all-purpose flour (or almond flour for gluten-free)
2 tablespoons chopped fresh parsley (optional, for garnish)
Salt and black pepper, to taste
1 tablespoon olive oil or butter (for sautéing)
Instructions
- Preheat oven to 375°F (190°C). Lightly grease a 9×9-inch casserole dish.

- Pour the mixture into the prepared dish and spread evenly.
- Top with reserved cheddar, mozzarella, and a sprinkle of Parmesan.
