Cheesy Beef and Hashbrown Casserole

Preheat your oven to 400°F (200°C) and lightly grease a 9×13-inch baking dish with cooking spray.
Heat a large skillet over medium-high heat. Add the ground beef and diced onion. Cook for 6 to 8 minutes, breaking the meat up with a wooden spoon, until the beef is fully browned and the onions are soft.
Drain off any excess grease from the skillet.
Stir in the minced garlic, paprika, garlic powder, salt, and pepper. Cook for just 1 more minute until the garlic is highly fragrant.

Reduce the skillet heat to low. Stir the condensed soup, sour cream, and milk directly into the seasoned beef until completely smooth and combined.
Stir in 1 cup of the shredded cheddar cheese, allowing it to melt gently into the beef mixture. Remove from heat.
Pour this rich, creamy beef mixture into the bottom of your prepared 9×13-inch baking dish and spread it into an even layer.

In a large mixing bowl, toss the thawed shredded hashbrowns with the melted butter, onion powder, and a pinch of salt and pepper. (The butter is the secret to getting that beautiful, oven-baked crunch!).
Spread the seasoned hashbrowns evenly over the top of the beef layer. Do not press them down too firmly—keeping them slightly loose helps the heat circulate so they get extra crispy.

Bake uncovered at 400°F (200°C) for 35 to 40 minutes. You will know it’s ready when the casserole is bubbling furiously around the edges and the hashbrowns on top have turned a beautiful golden brown.
Remove the casserole from the oven and immediately sprinkle the remaining 1 cup of cheddar cheese over the hot potatoes.
Return to the oven for an additional 5 minutes until the cheese is completely melted, gooey, and slightly speckled with brown.
Let it cool for 5 to 10 minutes before slicing and serving—this lets the layers set beautifully!

💡 Pro-Tips for the Best Casserole Ever

The Thawing Trick: Make sure your frozen hashbrowns are truly thawed before they go into the oven. If they are still icy, they will release too much water as they cook, resulting in a soggy casserole instead of a crispy one. If you’re in a rush, spread them out on a baking sheet and pop them in a warm oven for a few minutes to thaw quickly!
Garnish and Contrast: Because this dish is incredibly rich and savory, a pop of fresh contrast makes a massive difference. Top the finished casserole with chopped green onions, fresh chives, or a drizzle of your favorite hot sauce or ketchup just before serving.
Make It a Freezer Meal: You can assemble this entire dish through Step 3 ahead of time. Wrap the unbaked dish tightly in plastic wrap and aluminum foil, then freeze for up to 3 months. When ready to eat, thaw it overnight in the fridge and bake at 400°F, adding about 10-15 extra minutes to the initial covered baking time
