- Whisk eggs and cream in a large bowl until the mixture is smooth and slightly frothy. Season with salt, black pepper, and smoked paprika for depth of flavor.
- Combine all ingredients: Stir the cooked sausage and sautéed vegetables gently into the egg mixture. fold in cheddar cheese, reserving a small handful for topping.
- pour mixture into the prepared baking dish, spreading evenly. Sprinkle remaining cheese over the top for a golden crust.
- Bake uncovered for 35-40 minutes or until the casserole is set and the top is lightly browned. Insert a knife in the center; it should come out clean.
- Allow the casserole to cool for 5-10 minutes before slicing to maintain structure and enhance flavors.
