Ingredients

  • 2 lbs breakfast sausage
  • 2 large packages frozen shredded potatoes around 40 oz thawed
  • ¼ C butter
  • 1 can cream of mushroom or chicken Gluten free or regular
  • 1 C milk
  • 3 C shredded cheese cheddar or colby jack work well
  • ½ t salt
  • ¼ t pepper
  • ¼ t garlic powder

Instructions

  • Preheat the oven to 325°F.
  • Brown the sausage: In a large stockpot, cook the ground sausage over medium-high heat until fully browned. Strain off any excess grease and liquid, then return the sausage to the pot.
  • Melt the butter: Add the butter to the pot with the sausage and stir until fully melted.
  • Combine the casserole ingredients: Add the thawed shredded potatoes, cream of mushroom (or chicken) soup, milk, shredded cheese, salt, pepper, and garlic powder. Stir until everything is well combined.
  • Transfer to the baking dish: Pour the mixture into a 9×13 glass baking dish and spread it into an even layer.
  • Bake: Bake uncovered for 1 hour, or until the top is lightly golden and the center is cooked through.
  • Optional: Sprinkle extra cheese on top during the last 5–10 minutes of baking for an extra cheesy finish.

Notes

Variations for This Sausage Potato Casserole

  • Add ¼ cup finely chopped onions for extra flavor while browning the sausage.
  • Swap in turkey sausage or pork sausage—both work beautifully.
  • Add diced bell peppers for color.
  • Mix in green chiles for a Tex-Mex twist.
  • Use pepper jack cheese for a spicy casserole.
  • Add 1 cup sour cream for an extra creamy finish.

Tips for Success

  • Check the sausage ingredients. If it contains added salt, consider reducing the added salt in the recipe.
  • If the sausage is greasy or too much liquid, always strain it to remove excess grease; otherwise the casserole may become too soggy.
  • Thaw hash browns fully so the casserole bakes evenly.
  • For extra browning, broil the top for 2–3 minutes at the end.
