Why This Recipe Works

The key to this recipe is the combination of high-quality ingredients and careful cooking technique. By using a cast-iron skillet, I'm able to achieve a crispy crust on the bottom of the casserole, which adds texture and flavor to the dish.

The sausage is also an important component - I use a high-fat sausage to ensure that the casserole stays moist and flavorful. And by cooking the sausage in a skillet before adding it to the casserole, I'm able to bring out the natural flavors of the meat.

The eggs are also a crucial part of this recipe. By whisking them with salt, pepper, and a splash of cream, I'm able to create a rich and creamy texture that complements the sausage and cheese perfectly.

Finally, the cheese is the glue that holds the whole dish together. I use a combination of cheddar and parmesan to add depth and complexity to the casserole, and the result is a dish that's both familiar and exciting.

In a large bowl, whisk together the eggs, heavy cream, salt, pepper, dried parsley, and garlic powder.

Add the cooked sausage, cheddar cheese, and parmesan cheese to the bowl with the eggs and stir until well combined.

Remove the casserole from the oven and let it cool for a few minutes before serving.
