Step-by-Step Directions

1. Preheat oven to 350°F.
2. Heat a large nonstick skillet over medium-high heat until hot.
3. Add 2 lbs ground beef and 1 cup diced yellow onion to the skillet and cook.
4. Crumble the beef thoroughly as it cooks so it breaks up evenly.
5. Once beef is fully cooked and no pink remains, drain off excess grease.
6. Reduce heat to medium-low.
7. Stir in one 10.5 oz can condensed cream of mushroom soup and ½ cup milk until the beef is fully coated.
8. Spray a 9×13-inch baking dish with cooking spray.
9. Spread the beef and soup mixture evenly into the prepared baking dish.
10. Pour ½ cup melted butter into a large bowl and whisk in ½ teaspoon salt, ½ teaspoon pepper, 1 teaspoon onion powder, and 1 teaspoon garlic powder.
11. Add 20 oz thawed shredded hashbrowns to the bowl and stir to coat with the butter and seasonings.
12. Mix in 1 cup shredded mozzarella and cheddar cheese into the hashbrowns.
13. Spoon the seasoned hashbrown mixture evenly over the beef layer in the baking dish.

14. Bake in the preheated oven for about 1 hour and 15 minutes, until the hashbrowns begin to turn golden brown and crisp.

    

15. Remove the casserole from the oven and sprinkle the remaining ½ cup shredded mozzarella and cheddar cheese on top.
16. Return the casserole to the oven and bake about 5 more minutes until the top cheese melts.
17. Let the casserole rest for a few minutes after baking to firm up before serving.

Frequently Asked Questions

• Can I use a different type of ground meat?

  Absolutely! Ground turkey, chicken, or even breakfast sausage all work well here. Just remember if you use sausage, you might want to cut back on added salt.

• Do the hashbrowns need to be thawed?

  Yes, thawed hashbrowns mix better with the melted butter and spices — plus it helps them cook evenly while baking.

• Can I make this ahead of time?

  Yes! You can fully assemble it, cover tightly, and refrigerate for up to 24 hours before baking. For longer storage, just freeze the assembled casserole (wrapped well) for up to 3 months. For another make-ahead-friendly comfort dinner, try Chili Mac and Cheese.

• How should I reheat leftovers?

  Heat single portions in the microwave until hot, or warm the whole casserole in a 325–350°F oven, covered, until warmed through. If frozen, thaw overnight in the fridge for best results before reheating.

• Can I reduce the fat or calories?

  Definitely. Using lean ground meat, reducing butter or swapping it for a substitute, choosing a low-fat condensed soup, and using reduced-fat cheese all help cut fat and calories. You can also pair it with simple Sautéed Zucchini to keep the meal lighter.

• What oven temperature and bake time should I use?

  Bake at 350°F. It takes about 1 hour and 15 minutes until the hashbrowns start to brown, plus another 5 minutes for melting the extra cheese.

• How do I avoid a soggy casserole?

  Drain the beef well after cooking and make sure your hashbrowns are fully thawed and patted dry so there’s no extra water. Avoid overloading with soup and bake until the topping is nicely golden.

• Can I change the condensed soup or cheeses?

  Yes! Any cream-of soup works here, and cheeses like Monterey Jack, provolone, or Swiss are great alternatives or additions to mozzarella and cheddar.

• Can I use a different size baking dish?

  You can if it’s close in volume. Just remember if you make a smaller casserole, reduce bake time. For larger or doubled recipes, plan for extra time to ensure everything cooks through and the top browns nicely.
