Step-by-Step Instructions
Prepare the Cooking Environment
Preheat oven to 350°F and grease a 9×13-inch baking dish thoroughly with butter or cooking spray.
Brown the Sausage Foundation
In a large skillet, cook ground sausage over medium-high heat until browned and crumbly. Drain most fat, reserving 1 tablespoon. Set cooked sausage aside.
Create the Egg Custard
In a large bowl, whisk together room temperature eggs and warm milk until smooth. Add salt, pepper, and garlic powder, whisking until well combined.
Prepare the Biscuit Layer
Cut frozen biscuits into quarters. This prevents them from puffing too much and creates better integration with other ingredients.
Assemble the Layers
Layer quartered biscuits in the bottom of prepared baking dish. Sprinkle cooked sausage evenly over biscuits, followed by frozen hashbrowns and grated cheese.
Add the Binding Element
Pour egg mixture evenly over all layers, ensuring it reaches all areas of the dish. Do not stir – the layers should remain distinct.
Bake to Golden Perfection
Bake for 35-40 minutes until eggs are set, top is golden brown, and a knife inserted in center comes out clean.
Rest Before Serving
Allow casserole to rest for 10 minutes before serving. This helps layers set and makes cutting easier.
Recipe Notes & Tips
Biscuit Preparation – Keep biscuits frozen until cutting to prevent them from becoming gummy.
Egg Temperature – Room temperature eggs mix more easily and create smoother custard.
Layer Integrity – Don’t stir after adding egg mixture; distinct layers create better texture.
Doneness Testing – Check center with knife; it should come out clean when eggs are properly set.
Resting Importance – Allow cooling time for easier serving and better texture development.
