Step-by-Step Instructions
1. Prepare the Potatoes
Peel the potatoes and cut them into small, evenly sized cubes.
Partially cook the potato cubes in boiling salted water until they are just tender but not falling apart. Drain them well and allow them to cool slightly.
You can also steam or microwave the potatoes until partially cooked.
2. Preheat the Oven
Preheat your oven to 375°F (190°C).
Grease a large baking dish, approximately 9 × 13 inches (23 × 33 cm), with the butter.
3. Cook the Ground Beef
Heat a large skillet over medium heat.
Add the ground beef and season with salt, black pepper, garlic powder, and paprika.
Cook until the beef is thoroughly browned and no longer pink, breaking it apart with a wooden spoon as it cooks.
Drain any excess fat from the skillet.
4. Cook the Beef Bacon
Using the same skillet, cook the beef bacon until crispy.
Transfer it to a plate lined with paper towels to remove excess grease.
Once slightly cooled, crumble or chop the crispy beef bacon into small pieces.
5. Make the Casserole Mixture
Place the partially cooked potatoes in a large mixing bowl.
Add the cooked ground beef, sour cream, half of the shredded cheddar cheese, and half of the sliced green onions.
Season with a little additional salt and black pepper if needed.
Gently mix everything together until the potatoes are evenly coated and the ingredients are well distributed.
6. Assemble the Casserole
Transfer the mixture to the prepared baking dish.
Spread it evenly across the dish and gently press it into an even layer.
7. Add the Cheesy Topping
Sprinkle the remaining cheddar cheese evenly over the top.
Add the shredded mozzarella, making sure the entire surface is covered.
Finally, scatter the crispy crumbled beef bacon over the cheese.
8. Bake
Place the casserole in the preheated oven.
Bake uncovered for 20–25 minutes, or until the cheese is completely melted, bubbling, and lightly golden around the edges.
For an extra golden top, you can switch the oven to broil for the final 1–2 minutes. Watch carefully so the cheese does not burn.
9. Garnish and Serve
Remove the casserole from the oven and let it rest for about 5 minutes.
Sprinkle the remaining fresh green onions over the top.
Serve hot while the cheese is still creamy and melted.
Why You’ll Love This Recipe
This casserole combines several comforting ingredients in one easy dish.
The potatoes become tender and creamy while the seasoned ground beef adds plenty of savory flavor.
The sour cream creates a rich and creamy texture, while cheddar and mozzarella provide a deliciously cheesy topping.
Crispy beef bacon adds a smoky, savory crunch, while fresh green onions bring a bright finish.
It is also an excellent make-ahead dinner for busy families.
Best Tips for Success
Cut the potatoes into evenly sized cubes so they cook at the same rate.
Do not completely overcook the potatoes during the precooking stage. They should be tender enough to bite but firm enough to hold their shape during mixing and baking.
Drain the potatoes thoroughly before adding them to the casserole. Excess water can make the finished dish watery.
Brown the ground beef well to develop deeper flavor.
For the best melted cheese topping, shred the cheddar and mozzarella yourself if possible.
Let the casserole rest for a few minutes after baking. This allows the creamy filling to settle slightly and makes serving easier.
Best Ingredient Options
You can use russet potatoes, Yukon Gold potatoes, or another firm potato variety.
For the ground beef, an 80/20 blend provides excellent flavor, while leaner ground beef can be used for a lighter casserole.
Sharp cheddar gives the dish a stronger cheese flavor, while mild cheddar creates a softer and creamier taste.
Mozzarella adds excellent melting qualities and creates a stretchy cheese topping.
For extra flavor, you can add a small amount of chopped fresh parsley or chives before serving.
Recipe Variations
For a spicy version, add diced jalapeños, crushed red pepper flakes, or a little hot sauce to the beef mixture.
For a vegetable-loaded casserole, mix in sautéed bell peppers, mushrooms, broccoli, or corn.
For extra creaminess, stir a small amount of cream cheese into the sour cream before combining it with the potatoes.
For a smoky flavor, add a little smoked paprika to the ground beef seasoning.
For a stronger cheese flavor, replace part of the cheddar with Monterey Jack, Colby Jack, or another good melting cheese.
What to Serve With This Casserole
A fresh green salad provides a crisp contrast to the rich and cheesy casserole.
Steamed broccoli, green beans, or roasted vegetables are also excellent choices.
For a lighter meal, serve smaller portions with a large salad and fresh vegetables.
You can also serve this casserole as a hearty side dish alongside grilled beef or roasted chicken.
Make-Ahead Instructions
You can assemble the casserole several hours ahead of time.
Prepare the potatoes and beef, combine the ingredients, and transfer everything to the greased baking dish.
Cover tightly and refrigerate until ready to bake.
When ready to cook, remove the casserole from the refrigerator while the oven preheats. You may need to add a few extra minutes to the baking time if the casserole is still cold.
For best results, add the final cheese and beef bacon topping shortly before baking.
Storage
Allow leftovers to cool before transferring them to an airtight container.
Refrigerate within 2 hours and enjoy within 3–4 days.
Keep the casserole refrigerated until ready to reheat.
Reheating
For individual portions, microwave on medium power until heated through.
For larger portions, cover the casserole with foil and reheat in a 350°F (175°C) oven until hot.
Remove the foil during the final few minutes if you want the cheese topping to become bubbly again.
Freezing
This casserole can be frozen, although the texture of the potatoes and sour cream may change slightly after thawing.
For best results, cool the casserole completely, divide it into portions, and place it in freezer-safe containers.
Freeze for up to 2–3 months for the best quality.
Thaw overnight in the refrigerator before reheating.
Common Mistakes to Avoid
Do not overcook the potatoes before assembling the casserole. Very soft potatoes can break apart during mixing.
Avoid adding too much salt before tasting the mixture because the beef bacon and cheeses can already contribute significant saltiness.
Do not skip draining excess fat from the ground beef, especially when using a higher-fat blend.
Avoid baking the casserole for too long, as excessive cooking can dry out the potatoes and cause the cheese to become overly firm.
Let the casserole rest briefly before serving so the layers are easier to scoop and serve.

Frequently Asked Questions
Can I use frozen potatoes?
Yes. Frozen diced potatoes can be used, but check the package instructions and make sure they are appropriately cooked before adding them to the casserole.
Can I prepare this casserole ahead of time?
Yes. Assemble the casserole, cover it, and refrigerate it for several hours before baking.
Can I use only cheddar cheese?
Absolutely. You can replace the mozzarella with additional cheddar if you prefer a stronger cheddar flavor.
Can I make this casserole without sour cream?
Yes. Plain Greek yogurt can be used as an alternative, although it will have a slightly different flavor and texture.

How do I make the top extra crispy?
For a more golden and bubbly topping, place the casserole under the broiler for the final 1–2 minutes. Watch it carefully because the cheese can brown quickly.
