- Press: Spread the frozen hash browns evenly in the greased dish. Use a spatula to press them down firmly, creating a solid, crispy base.
- Whisk: In a large bowl, combine the beaten eggs, milk, sour cream, salt, pepper, paprika, and cayenne. Whisk until smooth and creamy, your muscles will feel that gentle mix!
- Mix: Fold in 1½ cups of shredded cheese and the sautéed vegetables from the skillet into the egg mixture, adding delicious layers to your casserole.
