Ingredients

1 pound ground beef

1 (30 oz) bag frozen shredded hashbrowns
½ cup sour cream
1 (10.5 oz) can condensed white cheddar soup
2 cups shredded Colby Jack cheese (divided)
1 (10 oz) can Rotel, undrained (or your favorite salsa)

Instructions

In a large skillet over medium heat, cook the ground beef until fully browned and crumbled. Drain excess grease and return the meat to the skillet.
Stir in 2 tablespoons of taco seasoning until evenly combined, then remove from heat.
Lightly grease your crock pot and spread the frozen shredded hashbrowns evenly across the bottom.
Layer the seasoned ground beef over the hashbrowns.
Add the remaining taco seasoning, sour cream, condensed white cheddar soup, 1½ cups of shredded cheese, and Rotel (with juices).
Stir everything gently in the crock pot until well combined.
Cover and cook on LOW for 4 hours or HIGH for 2 hours, until the hashbrowns are tender and slightly golden around the edges.
About 15 minutes before serving, sprinkle the remaining ½ cup cheese on top. Cover again and let it melt.
Serve warm with your favorite taco toppings.

Do I need to thaw the hashbrowns?
No, they go in frozen directly into the crock pot.
