Step-by-Step Instructions
- Prepare the Baking Dish:
- Begin by preheating your oven to exactly 375°F to ensure even cooking. Take a 9x13 inch baking dish and thoroughly grease it with butter or cooking spray, making sure to coat the corners well. This prevents any sticking and helps create crispy edges on your hashbrowns.
- Brown the Sausage:
- Place a large skillet over medium heat until it's hot enough that water droplets dance across the surface. Add the Jimmy Dean sausage, breaking it into small crumbles with a wooden spoon as it cooks. Continue cooking for 5 to 7 minutes until no pink remains and the sausage develops a golden brown color. Transfer to a paper towel lined plate to drain excess grease.
- Create the Base Layer:
- Spread the frozen hashbrowns in an even layer across the bottom of your prepared baking dish. No need to thaw them first as they'll cook perfectly from frozen. Sprinkle a pinch of salt and pepper directly onto the hashbrowns for extra flavor. Next, distribute the cooked sausage evenly over the hashbrowns, ensuring every bite will have some meat.
- Prepare the Gravy:
- In a medium mixing bowl, whisk together the gravy mix and cold milk until completely smooth with no lumps. The cold milk helps prevent lumps from forming. Pour this mixture slowly and evenly over the sausage and hashbrown layers, allowing it to seep down into all the crevices. This creates the rich, creamy foundation that will bind everything together.
- Add Cheese and Biscuits:
- Sprinkle the shredded cheddar cheese in an even layer across the top of the casserole. Take each Pillsbury biscuit and cut it into quarters using a sharp knife or kitchen scissors. Arrange the biscuit pieces across the top of the casserole, spacing them evenly but allowing some to overlap slightly. This creates the perfect biscuit to filling ratio and ensures even baking.
- Bake to Golden Perfection:
- Place the casserole on the center rack of your preheated oven. Bake for 25 to 30 minutes, checking at the 20 minute mark. The casserole is done when the biscuits have puffed up and turned a deep golden brown, the edges are bubbling, and the center is hot throughout. Allow the casserole to rest for exactly 5 minutes before serving to let the layers set up properly.

This casserole reminds me of Sunday mornings at my grandmother's house. She always said the secret to perfect gravy was patience and stirring constantly. While this recipe simplifies her technique, I still think of her every time the savory aroma fills my kitchen.
Make It Your Own
This casserole welcomes customization based on your family's preferences. For a spicier version, choose hot Italian sausage or add a few dashes of hot sauce to the gravy mixture. Vegetarians can enjoy it too by substituting plant based sausage crumbles. The texture will be slightly different, but the flavor profile remains delicious.
Storage and Reheating
Once cooled, cover any leftovers tightly with aluminum foil and refrigerate for up to 3 days. For best results when reheating, use the oven rather than the microwave. Preheat to 350°F and heat the covered casserole for about 15 minutes until warmed through. This method helps maintain the texture of the biscuits.
Pro Tips
Allow the casserole to sit for exactly 5 minutes before serving this helps the layers set properly

Enjoy this comforting casserole that brings everyone together around the breakfast table.
